How This Mortgage Calculator Works

This mortgage calculator estimates your monthly mortgage payments using the property price, deposit, interest rate, and mortgage term you enter.

It first works out your loan amount by subtracting your deposit from the total property price. It then applies a standard repayment mortgage formula to estimate how much you would pay each month over the full term of the mortgage.

The calculator also shows the total amount repaid, the total interest paid, and your loan-to-value ratio, giving you a quick view of the overall cost of borrowing.

Property priceThe total value of the home you want to buy.
DepositThe amount you pay upfront, which reduces how much you need to borrow.
Interest rateThe annual percentage rate applied to your mortgage balance.
Mortgage termThe number of years over which you repay the mortgage.

Mortgage Calculator FAQs

This mortgage calculator provides an estimate based on the values you enter. Actual mortgage payments may vary depending on lender fees, taxes, insurance, and the specific mortgage product you choose.
Most UK lenders require a deposit of at least 5% to 10% of the property value. However, putting down 20% or more can help you qualify for better mortgage interest rates.
You may reduce your monthly mortgage payment by increasing your deposit, securing a lower interest rate, or extending the loan term. Keep in mind that longer terms increase total interest paid.
Loan-to-value (LTV) is the percentage of the property price you borrow. For example, borrowing £240,000 on a £300,000 home means an LTV of 80%.

How This Stamp Duty Calculator Works

This stamp duty calculator estimates the Stamp Duty Land Tax due on a residential property purchase in England or Northern Ireland using the price and buyer details you enter.

It works by splitting the purchase price into tax bands and applying the correct rate to each portion, rather than charging one single rate across the whole property price.

The calculator also adjusts the result if first-time buyer relief applies, or if higher rates such as additional property or non-UK resident surcharges need to be included.

Buyer typeSelect first-time buyer only if the purchase qualifies for first-time buyer relief.

Stamp Duty Calculator FAQs

Stamp Duty Land Tax is a tax charged on many residential property purchases in England and Northern Ireland. The amount due depends on the purchase price and whether any reliefs or surcharges apply.
Eligible first-time buyers can pay less SDLT than standard buyers. Relief is only available if the property price and the buyer both meet the first-time buyer rules.
In many cases, if buying the new property means you will own more than one residential property, the higher additional-property rates may apply. Some replacement-of-main-home situations are treated differently.
Yes. If you enable the non-UK resident option, the calculator includes the residential non-UK resident surcharge in the estimate shown.
This calculator is useful for estimating SDLT, but some real purchases involve special rules, reliefs, lease treatment, mixed-use classifications, or linked transactions, so the final amount can differ.

How This Borrowing Calculator Works

This borrowing calculator estimates how much you may be able to borrow based on your income, a second applicant’s income, your monthly financial commitments, and the income multiple selected.

It starts by adding together both annual incomes, then applies an income multiple such as 4.0x, 4.5x, or 5.0x to estimate a lender-style borrowing range.

It then makes a simple adjustment for monthly commitments and combines the result with your available deposit to show an estimated overall property budget.

Borrowing Calculator FAQs

Many lenders use income multiples as a starting point, often somewhere around 4 to 4.5 times annual income, although some borrowers may be offered more or less depending on their situation.
Your deposit does not always increase the maximum loan amount directly, but it does improve your overall buying power by increasing your total property budget and potentially helping you access better mortgage rates.
Yes. Existing monthly commitments such as loans, car finance, credit cards, or childcare costs can reduce how much a lender is willing to offer because they affect affordability.
No. This calculator is only a guide. Real lenders will also look at your credit file, spending, dependants, employment type, deposit size, and interest rate stress testing before making an offer.
This calculator is designed to use gross annual income, which means your income before tax and other deductions are taken off.

Mortgage Overpayment FAQs

A mortgage overpayment is any extra money you pay on top of your normal monthly mortgage repayment. This can reduce your mortgage balance faster and lower the total interest paid.
Yes. Overpaying reduces the outstanding mortgage balance more quickly, which means less interest is charged over the life of the mortgage.
Many lenders allow regular overpayments, but some mortgages have limits or early repayment charges. Always check your lender’s terms before making large or frequent overpayments.
That depends on your goals, mortgage rate, and available savings options. Overpaying can reduce interest, but some people may prefer to keep cash accessible in savings or investments.
This calculator is an estimate only. Real results can differ depending on how your lender applies overpayments, whether your monthly payment changes, and any fees or restrictions in your mortgage agreement.

Remortgage Calculator FAQs

A remortgage is when you switch your existing mortgage to a new deal, either with your current lender or a different one, usually to get a better rate or lower monthly payments.
Remortgaging can be worth it if the new deal reduces your monthly payment or total borrowing cost enough to outweigh any arrangement fees, legal fees, or early repayment charges.
Yes. Fees can make a big difference to the real value of a new mortgage deal, especially if the monthly saving is small or the deal period is short.
The break-even point is how long it takes for your monthly savings to recover the upfront remortgage costs. After that point, any further savings are effectively net savings.
No. This calculator is a guide only. Actual remortgage costs and savings can vary depending on lender fees, legal costs, valuation charges, early repayment charges, and whether your term changes.

Compound Interest Calculator FAQs

Compound interest is interest earned not only on the original investment but also on the accumulated interest from previous periods.
Over long periods of time, compounding can significantly increase investment growth because returns continuously generate additional returns.
Compounding frequency depends on the investment or account type. Some accounts compound annually, quarterly, monthly, or even daily.
No. This calculator estimates nominal growth only and does not adjust for inflation, taxes, or investment fees.

How This Loan Repayment Calculator Works

This loan repayment calculator estimates your monthly loan payments based on the loan amount, interest rate, and repayment period.

The calculation uses a standard amortisation formula that spreads repayments across the entire loan term. Each monthly payment includes both interest and a portion of the original loan balance.

Over time, the interest portion of each payment gradually decreases while the amount applied to the loan balance increases.

Loan amountThe total amount borrowed from the lender.
Interest rateThe annual percentage rate applied to the loan balance.
Loan termThe length of time over which the loan will be repaid.
Monthly paymentsRegular repayments that gradually reduce the outstanding balance.

Loan Calculator FAQs

A loan repayment is the regular payment made to a lender to pay back borrowed money plus interest over a set period of time.
Most loans use amortised payments, meaning each monthly payment covers both interest and part of the loan principal until the balance is fully repaid.
Yes. Extending the loan term spreads repayments over a longer period, which reduces monthly payments but increases total interest paid.
No. This calculator provides an estimate only. Actual repayments may differ depending on lender fees, compounding methods, and repayment structures.

Salary After Tax FAQs

Salary after tax is the amount you keep from your gross pay after deductions such as income tax, National Insurance, pension contributions, and student loan repayments have been taken off.
Not necessarily. This calculator gives an estimate. Your actual payslip can differ depending on your tax code, salary sacrifice arrangements, benefits, bonuses, and other payroll adjustments.
Different UK regions can use different income tax bands, so selecting the correct region helps produce a more realistic take-home pay estimate.
Yes, pension contributions reduce your immediate take-home pay, but they can also reduce taxable income depending on how the contribution is handled.
Yes. If your earnings are above the repayment threshold for your plan, student loan deductions can reduce your take-home pay.

Savings Calculator FAQs

A savings calculator estimates how much money you could build up over time using a starting balance, regular contributions, and interest.
Yes. This calculator estimates savings growth using compounding, which means interest can be earned on both your original balance and previously earned interest.
The more often interest is added, the sooner it starts earning interest itself. Over longer periods, this can make a noticeable difference to your final balance.
No. It is an estimate only. Actual savings growth may differ depending on changing rates, account terms, fees, tax, and when contributions are made.
Yes, as a rough estimate. For investments, real returns can vary each year, so this works best as a simplified projection rather than a guaranteed result.

It applies interest to the remaining card balance each month, then reduces the balance by your chosen monthly payment and any extra overpayment you add.

The calculator shows the estimated repayment time, the total interest that could be charged, and the total amount you may repay before the balance is cleared.

Current balanceThe amount currently outstanding on the credit card.
APRThe annual percentage rate used to estimate monthly card interest.
Monthly paymentYour regular monthly repayment amount before any extra overpayments.
Extra paymentAn optional additional monthly amount to reduce the card balance faster.

Credit Card Interest FAQs

Credit card interest is the charge added to your outstanding balance when the full amount is not repaid by the due date. It is usually expressed as an APR.
A higher APR means interest is added more aggressively, which can make balances take longer to clear and increase the total amount repaid.
Yes. Paying extra each month reduces the balance faster, which means less interest is charged over time.
If your payment does not cover the monthly interest, the balance may not fall at all. In some cases it can effectively become impossible to clear without increasing payments.
No. It is an estimate only. Real card charges can differ depending on statement timing, fees, promotional periods, cash withdrawals, and how the provider applies interest.

How This Inflation Calculator Works

This inflation calculator estimates how the value of money changes over time when prices rise each year.

It works by applying an annual inflation rate across the number of years you enter, showing how much more money may be needed in future to buy the same thing.

The calculator also shows the reverse view by estimating the present-day buying power of a future amount, helping you understand how inflation can reduce purchasing power over time.

Current amountThe amount of money you want to project forward through inflation.
Inflation rateThe annual percentage increase used to estimate rising prices.
YearsThe number of years over which inflation is applied.

Inflation Calculator FAQs

Inflation is the rate at which prices rise over time. When inflation increases, the same amount of money generally buys less than it did before.
Inflation matters because it affects the real buying power of money. Even if the number in your bank account stays the same, what that money can actually buy may fall over time.
Future cost is the amount of money that may be needed in the future to buy something that costs a certain amount today, assuming inflation continues at the chosen rate.
This shows what a future amount is worth in today’s money. It helps explain how inflation reduces purchasing power over time.
No. This calculator is only a simple estimate. Real inflation changes year by year, so actual future price changes may be higher or lower.

How This VAT Calculator Works

This VAT calculator helps you quickly work out VAT on a price by either adding VAT to a net amount or removing VAT from a gross amount.

If you choose to add VAT, the calculator starts with the base price and adds the selected VAT rate to produce the total including VAT.

If you choose to remove VAT, the calculator starts with a VAT-inclusive amount and works backwards to estimate the net amount and the VAT portion.

AmountThe number you want to calculate VAT from, either net or gross depending on the mode selected.
VAT rateThe percentage used to calculate the VAT amount, such as 20%, 5%, or 0%.
Add VAT modeUse this when you have a net price and want the total including VAT.

VAT Calculator FAQs

VAT stands for Value Added Tax. It is a consumption tax added to many goods and services.
To add VAT, take the net amount and multiply it by the VAT rate, then add that VAT amount back onto the original price.
To remove VAT, divide the VAT-inclusive amount by 1 plus the VAT rate. This gives the net amount before VAT.
This calculator includes common rates such as 20%, 5%, and 0%, which are useful for many quick VAT calculations.
It is accurate for basic VAT maths, but it does not account for more complex VAT rules, sector-specific treatment, or invoicing edge cases.

How This Percentage Calculator Works

This percentage calculator helps you solve several common percentage problems in one place, including finding a percentage of a number, working out percentage increases and decreases, reversing a percentage increase, and comparing two values.

Depending on the mode you choose, the calculator uses the two input boxes in slightly different ways. For example, in percentage of mode, the first box is the percentage and the second is the number you want to apply it to.

For increase and decrease calculations, the tool compares an original value with a new value to show the percentage change. For reverse percentage mode, it works backwards from a final figure to estimate the original number before a percentage increase was applied.

Calculation modeSelect the type of percentage calculation you want to perform, such as percentage of a number or percentage increase.

Percentage Calculator FAQs

This calculator helps you solve common percentage questions, including finding a percentage of a number, percentage increases, decreases, reverse percentages, and percentage differences.
To find a percentage of a number, divide the percentage by 100 and multiply it by the base number. For example, 20% of 200 is 40.
Subtract the original number from the new number, divide the difference by the original number, and then multiply by 100 to get the percentage increase.
Reverse percentage means working backwards from a final number to find the original value before a percentage increase was added.
It is accurate for standard percentage calculations and quick estimates, although it does not replace professional financial or mathematical advice for more advanced use cases.

How This Discount Calculator Works

This discount calculator helps you work out how much money you save when a percentage discount is applied to a price. It shows the discount amount, the final sale price, and the total saving in a simple breakdown.

You start by entering the original price and the discount percentage. The calculator then multiplies the original price by the discount rate to find the amount taken off, before subtracting that from the original price to give the discounted total.

There is also an optional VAT setting so you can estimate the final amount when VAT is involved. This can be useful for comparing net and gross discount scenarios.

Original priceThe starting price before any discount is applied.
Discount rateThe percentage reduction you want to apply, such as 10%, 20%, or 50%.
VAT optionsYou can ignore VAT or estimate how the final price changes when VAT is applied before or after the discount.
Final priceThe calculator shows the new price after the discount and any VAT treatment selected.

Discount Calculator FAQs

This calculator works out the discount amount and final sale price after a percentage reduction has been applied to the original price.
To calculate a discount, multiply the original price by the discount percentage, then subtract that amount from the original price.
The sale price is the original price minus the discount amount. For example, if something costs £100 and has a 20% discount, the sale price is £80.
Yes. This calculator includes optional VAT settings so you can estimate outcomes when VAT is involved, although it is still designed as a simple discount tool.
It is accurate for standard discount maths and quick pricing estimates, but it does not account for retailer-specific pricing rules, multi-buy offers, or advanced tax scenarios.

How This ROI Calculator Works

This ROI calculator helps you measure the return on an investment by comparing how much you put in with the final value you got back. It gives you the profit, the ROI percentage, and the return multiple in one simple view.

ROI stands for return on investment. The basic formula is profit divided by the original investment, multiplied by 100. Profit is simply the final value minus the amount originally invested.

This makes ROI useful for comparing investments, business projects, marketing campaigns, property deals, or anything else where you want to understand how efficiently money has generated a return.

Investment amountThe amount of money originally invested or spent at the start.
Final valueThe total value received back from the investment, including the original amount and any gain or loss.
ProfitThis is the difference between the final value and the original investment amount.
ROI percentageThis shows the return as a percentage of the original investment, making different investments easier to compare.

ROI Calculator FAQs

ROI stands for return on investment. It measures how much profit or loss you made compared with the amount originally invested.
ROI is calculated by subtracting the investment amount from the final value to get profit, then dividing that profit by the original investment and multiplying by 100.
A good ROI depends on the type of investment, the risk involved, and the time period. A higher ROI is generally better, but it should always be judged in context.
Yes. If the final value is lower than the original investment, the profit becomes a loss and the ROI will be negative.
Basic ROI does not include time. It only compares the amount invested with the final value returned. For time-based comparisons, annualised return measures are more useful.

How This Break-Even Calculator Works

This break-even calculator helps you estimate how many units you need to sell before your business covers its costs. It compares fixed costs with the contribution made on each sale, which is the selling price minus the variable cost per unit.

A break-even point is reached when total revenue exactly matches total costs. At that stage, you are not making a profit, but you are not making a loss either.

This calculator also includes an optional target profit input, so you can estimate how many units and how much revenue you would need not just to break even, but to hit a chosen profit goal as well.

Fixed costsThese are costs that stay the same regardless of how many units you sell, such as rent, salaries, insurance, or software subscriptions.
Selling price per unitThis is the amount you charge customers for each product or service unit sold.
Variable cost per unitThese are the costs directly tied to each sale, such as materials, packaging, delivery, or transaction fees.
Contribution per unitThis is the amount each sale contributes towards covering fixed costs and then generating profit.

Example Break-Even Calculations

Simple Product Business
Fixed costs£5,000
Price per unit£50

Service-Based Business
Fixed costs£2,500
Price per job£200
Variable cost£50
Break-even = 17 jobs

Break-Even Calculator FAQs

The break-even point is the level of sales where total revenue equals total costs. At that point, the business has covered its expenses but has not yet made a profit.
Break-even units are calculated by dividing fixed costs by contribution per unit. Contribution per unit is the selling price per unit minus the variable cost per unit.
Fixed costs stay the same regardless of sales volume, while variable costs change depending on how many units you sell or deliver.
Contribution per unit shows how much each sale contributes towards covering fixed costs. Once fixed costs are covered, further contribution becomes profit.
If your selling price is equal to or lower than your variable cost per unit, you cannot break even because each sale does not contribute enough to cover fixed costs.

How This Profit Margin Calculator Works

This profit margin calculator helps you work out how much profit you make on each unit sold and how profitable your pricing is overall. It compares your cost price with your selling price and then calculates margin, markup, and total profit.

Profit margin shows profit as a percentage of the selling price. Markup shows profit as a percentage of the cost price. These two figures are related, but they are not the same, which is why many businesses find it useful to see both.

By including quantity sold, this calculator also estimates total cost, total revenue, and total profit, making it useful for ecommerce, retail, freelancing, and small business pricing decisions.

Cost price per unitThis is how much it costs you to produce, buy, or deliver one unit of your product or service.
Selling price per unitThis is the price charged to the customer for one unit sold.

Profit Margin Calculator FAQs

Profit margin is the percentage of the selling price that remains as profit after the cost price has been deducted.
Margin is based on selling price, while markup is based on cost price. They measure profitability in different ways, so the percentages are not usually the same.
Profit margin is calculated by dividing profit per unit by selling price, then multiplying by 100.
Yes. If your selling price is lower than your cost price, you are making a loss and the profit margin will be negative.
This calculator is useful for retailers, freelancers, ecommerce sellers, service businesses, and anyone setting prices or checking product profitability.

How This House Affordability Calculator Works

This house affordability calculator gives a rough estimate of how much property you may be able to afford based on your annual income, monthly financial commitments, deposit, mortgage rate, and term.

The calculator starts with a simple income multiple to estimate the size of mortgage you may be able to borrow. It then reduces that figure to reflect any ongoing monthly debts or commitments, which can affect affordability in real mortgage assessments.

Once the estimated mortgage is calculated, the calculator adds your deposit to estimate a maximum property price and uses the interest rate and term to show an estimated monthly mortgage payment.

Annual household incomeThis is the total yearly income used to estimate how much a lender may be willing to offer.
Monthly commitmentsThese include debts and regular obligations such as loans, car finance, credit cards, or maintenance payments.
DepositYour deposit reduces the mortgage needed and increases the maximum property price you may be able to buy.
Affordability multipleThis is the income multiplier used to estimate borrowing, such as 4x, 4.5x, or 5x income.

House Affordability Calculator FAQs

This calculator estimates how much property you may be able to afford based on income, debts, deposit, and mortgage assumptions. It is designed as a guide rather than a lender decision tool.
An affordability multiple is the number used to estimate borrowing based on income. For example, borrowing at 4.5 times income means a household earning £60,000 may be estimated to borrow around £270,000 before other adjustments.
Yes. Existing monthly commitments can reduce how much you may be able to borrow because lenders usually consider your other financial obligations when assessing affordability.
No. This is only a general estimate. Actual lender decisions depend on credit history, income type, deposit size, property details, outgoings, and lender-specific rules.
The monthly payment estimate helps give context to the borrowing figure, so you can see how the estimated mortgage might translate into an approximate repayment amount.

How This Unit Price Calculator Works

This unit price calculator helps you compare two products to see which one offers better value for money. Instead of only looking at the shelf price, it works out the cost per unit so you can compare items fairly.

You enter the price and size of each product, then choose the unit type such as grams, kilograms, millilitres, litres, or items. The calculator then works out the price per unit for both options.

This makes it easier to compare different pack sizes, multipacks, and promotional offers when shopping for groceries, household goods, drinks, toiletries, and other everyday products.

Product priceEnter the total shelf price or purchase price for each product you want to compare.
Product sizeEnter the size, weight, volume, or quantity of each product using the same measurement type for both.
Unit typeChoose the unit that matches the products, such as grams, kilograms, millilitres, litres, or items.
Best valueThe calculator shows which product has the lower price per unit and therefore offers better value.

Unit Price Calculator FAQs

A unit price calculator works out the price per unit for each product, making it easier to compare different sizes and see which option offers better value.
Unit price helps you compare products fairly, especially when pack sizes are different. A bigger item is not always better value unless the price per unit is lower.
Yes. For the comparison to be meaningful, both products should be entered using the same measurement type, such as both in grams or both in litres.
Yes. This calculator is useful for groceries, drinks, toiletries, cleaning products, bulk purchases, and any items sold by size, weight, volume, or count.
No. A lower total price does not always mean better value. The better-value option is the one with the lower price per unit.
const unitFaq = document.querySelectorAll(".unit-content .faq-item"); unitFaq.forEach(item => { const btn = item.querySelector(".faq-question"); btn.addEventListener("click", () => { const open = item.classList.contains("active"); unitFaq.forEach(i => { i.classList.remove("active"); i.querySelector(".faq-answer").style.maxHeight = null; }); if (!open) { item.classList.add("active"); const answer = item.querySelector(".faq-answer"); answer.style.maxHeight = answer.scrollHeight + "px"; } }); });

How This Fuel Cost Calculator Works

This fuel cost calculator estimates how much fuel a journey will use and how much that trip is likely to cost based on distance, fuel price, and your vehicle’s fuel efficiency.

You can use either miles with MPG or kilometres with litres per 100km, depending on which format is more familiar. The calculator converts the figures into an estimated fuel usage in litres and then multiplies that by the fuel price.

It also shows extra context like return trip cost, cost per mile or kilometre, and a monthly estimate based on how many times you make that trip.

Trip distanceEnter the one-way distance for the journey you want to estimate.
Fuel priceUse the current cost per litre of fuel so the estimate reflects recent prices.
Fuel efficiencyChoose MPG if using miles, or litres per 100km if using kilometres.
Monthly tripsAdd how many times you make the journey each month to estimate regular fuel spending.

Fuel Cost Calculator FAQs

This calculator estimates how much fuel a trip will use and how much that fuel is likely to cost based on the distance, price per litre, and fuel efficiency entered.
Yes. You can switch to miles plus MPG mode if that matches how you normally measure distance and economy.
Yes. The calculator also supports kilometres and litres per 100km, which is common in many vehicles and countries.
The main trip cost is one way, but the calculator also shows an estimated return trip cost separately for convenience.
It is a useful estimate, but actual fuel use can vary based on traffic, weather, driving style, load, terrain, and the real-world efficiency of the vehicle.

BMI Calculator FAQs

BMI stands for body mass index. It is a simple calculation that uses height and weight to estimate a body size category.
In metric units, BMI is calculated by dividing weight in kilograms by height in metres squared.
No. BMI is a screening measure based on height and weight. It does not directly measure body fat, muscle mass, or overall health.
Yes. People with higher muscle mass can sometimes have a higher BMI without that reflecting body fat in the same way.
BMI is a general screening tool and may not reflect every individual equally. It is best interpreted with wider context rather than on its own.

How This Image Tools Hub Works

This Image Tools Hub groups together several browser-based file tools inside one clean section. Instead of scattering lots of separate image tools across the page, the hub uses top tabs so users can switch between image conversion, resizing, compression, and image to PDF without leaving the same tool area.

The current setup is designed to be practical for quick everyday tasks. You can convert image formats, resize images to new dimensions, reduce file sizes with compression, and combine multiple images into a single PDF file. All of these tools are built to feel like part of one connected interface rather than a loose collection of unrelated widgets.

This structure also makes the site easier to scale. More visual tools can be added later, such as crop, rotate, watermark, or PDF to image, while keeping the menu clean and the user experience consistent.

One hub, multiple image toolsConvert, resize, compress, and image to PDF all sit inside one shared image tools section.
Browser-based workflowThese tools are designed for lightweight image tasks directly in the browser, which keeps them fast and simple for everyday use.
Expandable structureThe hub layout makes it easy to add future tools like crop, rotate, watermark, and PDF to JPG later.

How this date difference calculator works

This calculator measures the difference between two calendar dates and shows the result in several useful formats. You can see the total number of days, the total number of weeks, and a calendar-style breakdown in years, months, and days.

It is useful for planning trips, measuring time between important milestones, checking contract dates, counting down to events, and working out exact date spans for personal or business use.

Total daysTotal weeksCalendar monthsCalendar yearsInclusive option

When the inclusive option is turned on, the calculator counts both the start date and the end date. When it is turned off, it shows the standard difference between the two dates.

What “total days” means

Total days is the full number of days between the two dates. This is often the most useful result for countdowns, project timelines, booking windows, and deadline planning.

Why months and days can look different

Calendar months are not all the same length, so a date span can have one total day count and a different calendar-style result in years, months, and days. Both are correct, just shown in different ways.

Reversed dates are handled automatically

If you enter the later date first, the calculator automatically reorders the dates and still gives you the correct result.

Works for leap years too

The calculator uses real calendar dates, so leap years and varying month lengths are taken into account automatically.

Example date differences

Here are a few common examples showing how the calculator can be used for everyday date calculations.

Date difference calculator FAQs

It calculates the time between two dates and shows the result as total days, total weeks, and a calendar breakdown in years, months, and days.
When inclusive mode is turned on, both the start date and the end date are counted in the final total. This is useful for event schedules, bookings, and date ranges where both days should be included.
The calculator automatically swaps the dates and still gives you the correct difference, so you do not need to re-enter them.
Months do not all contain the same number of days, so a result shown as calendar months and days will not always map neatly to a fixed number of days per month. Both formats are valid and useful for different situations.
Yes. The calculator uses actual calendar dates, so leap years and varying month lengths are included automatically in the result.
It is accurate for standard calendar date calculations. It is designed for everyday use such as planning, countdowns, age spans, timelines, and date checks.

How this work hours calculator works

This calculator helps you work out how long a shift lasts, how much unpaid break time to subtract, how many paid hours remain, and what those paid hours are worth at your chosen hourly rate.

It is useful for employees, freelancers, shift workers, managers, and anyone who needs to estimate hours worked or calculate expected pay from start and end times.

Shift lengthUnpaid breakPaid hoursHourly payOvernight shifts

The calculator first measures the total shift length between your start time and end time. It then subtracts your unpaid break to show paid hours. If you enter an hourly rate, it also estimates total pay for that shift.

What counts as paid hours

Paid hours are the time left after subtracting any unpaid break. For example, an 8 hour shift with a 30 minute unpaid break results in 7 hours and 30 minutes of paid time.

Overnight shift support

If your shift ends after midnight, turn on overnight mode. This tells the calculator that the end time falls on the next day instead of the same day.

Decimal hours and hours plus minutes

The calculator shows paid time in both formats. This helps if you need a simple hours-and-minutes answer or a decimal value for payroll and invoicing.

Pay estimate

The total pay estimate is based on your hourly rate multiplied by paid hours only. It does not include overtime rules, bonuses, tax, or deductions.

Work hours calculator FAQs

It calculates the total length of a shift, subtracts any unpaid break, shows paid hours, and estimates total pay using your hourly rate.
Paid hours are calculated by taking the total shift length and subtracting the unpaid break. The result is shown in both hours and minutes, and decimal hours.
Overnight shift means your end time falls on the next day rather than the same day. For example, a shift from 22:00 to 06:00 should use overnight mode.
Yes. Enter an hourly rate and the calculator will estimate total pay based on paid hours after subtracting the unpaid break.
No. This version uses a single hourly rate for the whole shift. It does not apply separate overtime rules, multipliers, or different rates for different time periods.
The calculator will still show total shift length and paid hours. The pay result will simply be based on the rate entered, so a blank or zero rate gives a zero pay estimate.
In this calculator, break time is treated as unpaid and is deducted from the total shift length before pay is estimated.
It is accurate for standard shift-length and pay estimates based on the values you enter. It is designed for everyday scheduling, planning, and quick payroll-style calculations.

How this currency converter works

This currency converter lets you compare one currency against another using live reference exchange rates. Enter an amount, choose the source currency, choose the target currency, and the tool calculates the converted amount automatically.

It is useful for travel planning, budgeting, pricing comparisons, online shopping, invoicing estimates, and quick exchange-rate checks.

Live ratesMajor currenciesInstant conversionSwap currenciesRate date shown

The calculator fetches the latest available reference rate for the selected currency pair, then applies that rate to the amount you enter. After the rate is loaded, the result can update live while you change the amount.

What the exchange rate means

The exchange rate shows how much one unit of the source currency is worth in the target currency. For example, if 1 GBP equals 1.27 USD, then every pound converts at that reference rate.

Why final rates can differ

Banks, cards, travel money providers, and transfer services often add margins or fees. That means your final transaction rate may differ from the reference rate shown here.

Why the date matters

Exchange rates move over time, so the rate date helps you understand when the quoted reference rate was published and how current the result is.

Who this tool is for

This tool is useful for everyday users, travellers, freelancers, small businesses, online shoppers, and anyone who wants a quick reference conversion without using a banking app.

Yes. It is useful for budgeting and comparing prices when travelling, especially when you want a quick reference estimate in your home currency.
The inverse rate shows the opposite direction of the conversion. For example, if 1 GBP equals 1.27 USD, the inverse tells you how many GBP 1 USD is worth.
The rate date shows when the reference exchange rate was published, which helps you understand how recent the conversion data is.
Yes. You can swap the source and target currencies instantly using the swap button to compare the reverse conversion.
It is accurate for reference-rate conversions based on the latest available data from the selected source. For actual transactions, your provider’s rate and fees may change the final amount.

How this password generator works

This password generator lets you create either a strong random password or a more memorable passphrase. Random password mode is best when you want maximum unpredictability, while passphrase mode is useful when you want something easier to read, type, and remember.

You can choose the password length and character types in random mode, or switch to passphrase mode and generate a phrase using real words with optional separators, capital letters, numbers, and symbols.

Random passwordsMemorable passphrasesAdjustable lengthNumbers and symbolsCopy instantly

This makes the tool useful for a wide range of situations, from secure account logins to memorable phrases for apps, devices, and password managers.

Random password mode

Random password mode builds a password from the character types you select, such as uppercase letters, lowercase letters, numbers, and symbols. This is a strong choice when you want maximum randomness.

Passphrase mode

Passphrase mode creates a string of real words, such as words joined by hyphens or underscores. This can make the result easier to type and remember while still staying strong when enough words are used.

Why length matters

Whether you use a password or a passphrase, length is one of the biggest factors in strength. Longer results are generally much harder to guess or brute-force.

Best practice for security

The safest approach is to use a unique password or passphrase for every account and store it in a trusted password manager so you do not need to memorise everything yourself.

Example password generator settings

Here are a few common ways to use random password mode and passphrase mode for different types of accounts.

Password generator FAQs

It creates either a random password or a memorable passphrase based on the settings you choose, so you can generate stronger login credentials quickly.
A random password usually uses mixed characters such as letters, numbers, and symbols. A passphrase uses several real words joined together, which can make it easier to read, type, and remember.
A passphrase can be very strong when it is long enough and uses enough words. Adding capital letters, numbers, or symbols can make it even stronger.
Use random password mode when you want maximum unpredictability and do not need to remember the result manually. Use passphrase mode when you want something easier to type or remember.
Longer results are generally stronger. A random password of 12 to 16 characters is a solid starting point, and a passphrase with 4 or more words is usually much stronger than a short simple password.
They can increase variety and strength, especially in random password mode. In passphrase mode, adding a number or symbol can provide an extra layer while keeping the phrase readable.
It is much safer to use a different password or passphrase for every account. Reusing the same one increases the risk that a single breach could affect several accounts.
This tool generates results in your browser and is designed for everyday password creation. For best security, use the result immediately and store it safely in a trusted password manager.
The strength label is a quick estimate based on factors such as length and character variety. It is useful as a guide, but the best overall security still comes from using long, unique passwords for every account.

How this random number generator works

This random number generator lets you create one or more random values within a range you choose. You can set a minimum number, a maximum number, how many results you want, and whether duplicates are allowed.

It is useful for classroom activities, games, raffles, prize draws, lucky numbers, random selections, practice exercises, and quick everyday decisions.

Random resultsCustom rangeSingle or multiple numbersDuplicates on/offWhole numbers or decimals

The calculator generates random values between your minimum and maximum settings. If whole-number mode is turned on, the results are integers. If it is turned off, the tool can generate decimal values instead.

How the range works

The minimum number is the lowest possible result and the maximum number is the highest possible result. Every generated value will fall inside that chosen range.

What duplicates means

If duplicates are allowed, the same number can appear more than once in the results. If duplicates are turned off, each result will be unique within the selected range.

Whole numbers and decimals

Whole-number mode is best for draws, games, and simple picks. Decimal mode is useful when you want a random value that includes fractional numbers.

When unique results matter

Unique results are useful for raffle numbers, team picks, classroom selection, and other situations where the same result should not repeat.

It is useful for website design, social graphics, branding ideas, presentations, product mockups, mood boards, and any creative project where you want colours that feel balanced.

HEX pickerPalette generatorRGB and HSLIntensity controlCopy colours instantly

The palette generator starts with one base colour and creates related colours using common colour relationships such as analogous, complementary, split complementary, triadic, and monochromatic. The intensity slider changes how subtle or bold the resulting palette feels.

What the palette types mean

Analogous palettes stay close together on the colour wheel, complementary palettes use opposite colours for contrast, and triadic palettes spread colour more evenly for a brighter look. Monochromatic palettes keep the same hue and vary lightness and saturation.

What the intensity slider does

Lower intensity creates softer and safer palettes, while higher intensity creates stronger contrast and more vivid colour combinations. It gives you a quick way to move from subtle to bold.

Why HEX, RGB, and HSL matter

HEX is common in design tools and CSS, RGB is useful for digital colour values, and HSL makes it easier to understand hue, saturation, and lightness when adjusting colours creatively.

Who this tool is for

This tool is useful for designers, marketers, content creators, developers, students, and anyone who wants a fast way to build colour combinations without opening heavy design software.

Colour picker FAQs

It lets you pick a base colour, view its HEX, RGB, and HSL values, and generate matching palettes that work well together for design and creative projects.
A colour palette is a set of colours chosen to work together visually. A good palette helps create consistency, contrast, and balance across websites, graphics, brands, and interfaces.
The intensity slider changes how gentle or bold the generated palette feels. Lower settings create more subtle colour variation, while higher settings create stronger contrast and more vivid combinations.
Analogous colours sit close together on the colour wheel and usually feel harmonious and calm. Complementary colours sit opposite each other and create stronger contrast.
Yes. You can copy individual HEX values for single swatches or copy the whole generated palette to use in design tools, code, or content workflows.
Different tools and workflows use different colour formats. HEX is common for web and design tools, RGB is useful for digital display values, and HSL makes colour relationships easier to understand and adjust.
Yes. It is useful for choosing a primary brand colour, accent colours, highlight colours, and contrast colours for websites, apps, dashboards, and landing pages.
It is accurate for colour selection, palette generation, and value conversion in normal design use. Final appearance can still vary slightly depending on screens, devices, and editing software.

It is useful for websites, buttons, forms, apps, dashboards, banners, slides, and any design where text needs to stay readable against a coloured background.

Contrast ratioLive previewText and backgroundPass / fail checksAccessible design

The tool measures the brightness difference between your foreground and background colours. Stronger contrast usually makes text easier to read, while weak contrast can make body text hard to see, especially on smaller screens or in bright light.

What contrast ratio means

The contrast ratio shows how different two colours are in perceived brightness. A higher ratio means the colours are easier to distinguish, which usually improves readability for text and interface elements.

Why normal text needs more contrast

Small body text is harder to read than large bold text, so it usually needs stronger contrast. A combination that works for a headline may still be too weak for paragraphs or captions.

Why this matters in design

Good contrast helps more people read and use your content comfortably. It improves clarity on websites, apps, forms, calls to action, and any design where text appears over colour.

Best use with your colour picker

A palette can look attractive but still fail for readability. This is why a contrast checker works so well after choosing colours: it helps validate whether the combination is practical for real text and UI use.

Example contrast checker scenarios

Here are a few common examples showing how contrast checking helps with websites, interfaces, and marketing graphics.

Contrast checker FAQs

It checks how readable a text colour is against a background colour by calculating the contrast ratio and showing whether that combination is likely to work for different text sizes and interface uses.
A contrast ratio measures the visual difference in brightness between two colours. Higher contrast usually makes text easier to read, especially for smaller body text.
Large text is easier to read than small body text, so it can still work with slightly lower contrast. Small text usually needs a stronger colour difference to stay readable.
Yes. This tool is useful for buttons, links, labels, icons, panels, cards, navigation, and any interface where text or graphics appear on top of a background colour.
Yes. Swapping colours is useful because a design may use one colour as text in one place and as a background in another. The tool helps you compare both directions quickly.
Good contrast helps more people read and use digital content comfortably, including users viewing screens in bright light and people who find faint colour combinations harder to distinguish.
No. Two colours can look attractive together and still be difficult to read when used for text and background. That is why contrast checking is important after palette selection.
It is accurate for normal colour contrast calculations and practical design checking. Final appearance can still vary slightly depending on screens, device settings, and the size or weight of the text in your design.

How this gradient generator works

This gradient generator helps you build smooth colour blends for websites, backgrounds, graphics, buttons, banners, and other design work. You can choose a linear or radial gradient, set the angle, pick multiple colour stops, and copy the final CSS code instantly.

It is useful for designers, developers, marketers, creators, and anyone who wants visually appealing gradients without opening heavier design software.

Linear gradientsRadial gradients2 to 4 colour stopsCustom anglesCopy CSS

The tool combines your chosen colours and positions into a CSS gradient string. You can adjust the direction, spacing, and number of stops to create everything from subtle backgrounds to bright, multi-colour hero sections.

What a colour stop does

A colour stop tells the gradient where one colour should appear and how it should blend into the next one. More stops let you create more layered, detailed gradients.

Linear vs radial gradients

Linear gradients move in a direction, such as top to bottom or corner to corner. Radial gradients spread outward from a centre point, which makes them useful for glows, spotlight effects, and soft background shapes.

Why angle matters

The angle controls the direction of a linear gradient. Small changes can completely change the feel of a design, especially for headers, overlays, hero sections, and cards.

Why copyable CSS is useful

The CSS output lets you move quickly from design idea to implementation. This is especially useful for websites, landing pages, dashboards, email banners, and front-end mockups.

Gradient generator FAQs

It helps you create linear or radial gradients using multiple colour stops, custom angles, and live preview, then gives you CSS code you can copy and use in your own projects.
A linear gradient blends colours in a direction, such as top to bottom or corner to corner. A radial gradient spreads colours outward from a centre point in a circular pattern.
A colour stop defines where a colour appears in the gradient. Changing the position of each stop changes how quickly one colour blends into another.
Yes. This tool lets you create gradients with 2, 3, or 4 colour stops, which is useful for more detailed or expressive visual styles.
The angle changes the direction of a linear gradient. For example, 90 degrees creates a horizontal gradient, while 180 degrees creates a vertical downward gradient.
Yes. The tool gives you a CSS gradient string that you can copy directly into websites, landing pages, apps, templates, and front-end projects.
Yes. The random option is useful when you want quick inspiration, visual exploration, or a starting point for a new design direction.
It is accurate for creating CSS gradient values and previewing how the result should look in standard digital design use. Final appearance can still vary slightly depending on screens and rendering context.

How this box shadow generator works

This box shadow generator helps you build CSS shadows for cards, buttons, panels, modals, images, and other interface elements. You can control the horizontal offset, vertical offset, blur, spread, opacity, colour, and whether the shadow sits outside or inside the element.

It is useful for web design, app interfaces, landing pages, dashboard UI, and any visual layout where you want to add depth, separation, or focus.

Horizontal offsetVertical offsetBlur and spreadInset toggleCopy CSS

The tool generates a live preview and a copy-ready CSS box-shadow value. Small changes can make a box feel softer, stronger, flatter, more elevated, or more pressed into the surface.

What horizontal and vertical offset do

The horizontal offset moves the shadow left or right, while the vertical offset moves it up or down. Together, they change the apparent direction of the light source.

What blur and spread do

Blur controls how soft the edge of the shadow feels. Spread changes the size of the shadow before blur is applied, which can make the result feel tighter or more dramatic.

What an inset shadow is

Inset shadows appear inside the element rather than outside it. They are useful for pressed buttons, input fields, inner depth effects, and subtle surface styling.

Why box shadows matter in UI

Shadows help create visual hierarchy and separation. Used well, they can make interfaces feel clearer and more polished by helping important elements stand out from the background.

Box shadow generator FAQs

It helps you create CSS box shadows by adjusting offset, blur, spread, opacity, colour, and inset settings, then shows the result in a live preview and gives you copy-ready CSS.
A box shadow is a visual effect that adds depth around or inside an element. It is commonly used on cards, buttons, images, forms, panels, and pop-ups to help them stand out.
Blur softens the edges of the shadow. Lower blur makes the shadow feel tighter and sharper, while higher blur creates a softer and more diffused look.
Spread changes the size of the shadow area before blur is applied. Positive spread makes the shadow larger, while negative spread pulls it inward for a tighter effect.
An inset shadow appears inside the element instead of outside it. This is useful for creating pressed buttons, input depth, or inner shading effects.
Yes. It is useful for buttons, cards, modals, menus, input fields, images, banners, and many other interface components where depth helps improve visual hierarchy.
Yes. The generator gives you a CSS box-shadow value that you can copy directly into websites, apps, components, templates, and design systems.
It is accurate for CSS shadow generation and live visual preview in normal design use. Final appearance can still vary slightly depending on background colour, screen settings, and surrounding layout context.

Damage rollsRoll 2d6 for heavier hits, weapon effects, and spell bursts.
Character generationUse 4d6 drop lowest to create classic RPG stat lines.
Percentile outcomesUse d100 for loot tables, event odds, and random encounter checks.
Back to calculator

FAQ

Dice Roller questions

Does the roller support dropping the lowest die?

Yes. Turn on Drop lowest and the lowest result is visually dimmed, excluded from the total, and listed separately in the dropped rolls area.

Can I use it for D&D-style stat generation?

Yes. The built-in 4d6 drop lowest preset is designed for that exact use case and keeps the workflow quick on both desktop and mobile.

What does the staged total build-up do?

Instead of jumping straight to the final result, the total adds up in sequence using the kept rolls. That makes multi-die rolls easier to verify at a glance.

Why do dropped dice look faded?

Dropped dice are intentionally dimmed so it is immediately obvious which values counted and which ones were excluded from the final total.

Can I restyle the back link destination?

Yes. The included link returns to the Dice Roller section using the tool anchor. If your calculator hub uses a different Carrd anchor, swap the href to match that section.

How this wheel of names works

This wheel of names lets you paste in a list of names, spin a visual wheel, and select one result at random. It is designed to be both practical and enjoyable to use, combining a polished wheel animation with options like spin intensity, pointer style, colour scheme, duplicate removal, and winner removal.

It works well for classrooms, giveaways, raffle-style picks, team selection, random decisions, and any situation where you want a fair visual picker instead of a plain list-based random result.

Name wheelSpin intensityArrow stylesColour themesWinner removal

Each name becomes a segment on the wheel. When you spin, the wheel rotates under the fixed arrow and lands on a final winning segment. You can also remove winners after each spin if you want no-repeat results for raffles, draft order, or group selection.

Great for visual selection

A wheel adds excitement and makes the random choice easier to follow. This is especially useful when you want the process to feel fair, transparent, and engaging for everyone watching.

Useful beyond games

It works well for classroom participation, giveaway winners, meeting order, chores, names in a hat, team picks, and many other quick decision-making tasks.

Remove winner for no-repeat spins

The remove winner option makes the tool more useful for raffles, team assignment, and any multi-round selection where the same name should not be picked again.

Styles change the feel, not the result

The colourway and arrow style settings are visual only. They help the wheel feel more premium and themed, while the actual result stays random.

Wheel of names FAQs

It creates a spinning name wheel from your list and picks one result at random when the wheel stops. It is a visual alternative to a plain random name picker.
You can add a long list of names, one per line. Very large lists may make the labels smaller, but the wheel can still be used for bigger groups and entry pools.
It removes repeated names so each unique name only appears once on the wheel. This is useful if you want every person or item to have the same chance regardless of accidental duplicates.
It removes the selected winner from the wheel after each spin. That makes it useful for raffles, no-repeat selection, multiple rounds, and team allocation.
No. Spin intensity changes the feel of the animation, such as how long or dramatic the spin appears, but it does not make any name more or less likely to win.
No. These are visual customisation options only. They help the tool feel more themed and polished, but they do not change the random outcome.
Yes. It is especially useful for classroom selection, giveaway winners, raffle draws, meeting order, random turn order, and group activities where a visual random picker is more engaging.
Yes. The selected result is random within the list on the wheel, and each remaining name has an equal chance of being chosen.

How this meme generator works

This meme generator lets you upload an image, add top and bottom captions, preview the result live, and export the final meme as an image. It is designed for fast browser-based meme creation without needing any design software.

It also includes auto caption ideas. These are suggestion-based caption prompts created from your chosen tone, caption format, and optional image context. They are meant to help with meme writing rather than automatically understanding the image.

Image uploadTop and bottom captionsAuto caption ideasStyle presetsDownloadable result

The preview updates as you type, so you can quickly test different caption ideas, styles, and text sizes. This makes it useful both for quick jokes and for more polished meme-style posts.

Good for fast meme making

You can upload an image, add text, and generate a simple finished meme quickly without leaving the page or using a separate graphics app.

Auto caption ideas help when you are stuck

If you know the vibe but not the exact wording, the suggestion tool can generate caption ideas based on tone and format so you can start with something and tweak it.

Style presets change the feel

Classic, clean, poster, and subtitle-style captions give the meme a different look depending on whether you want an old-school meme feel or a cleaner social style.

Context improves caption suggestions

The optional image context box makes the caption ideas feel more relevant. Even a short description like “shocked cat” or “tired office worker” helps the suggestions feel better.
