Estimate your monthly payment, total interest, and overall loan cost.
This calculator uses the standard repayment mortgage formula and gives an estimate only. It does not include fees, insurance, or taxes.
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.
Estimate your Stamp Duty Land Tax for residential purchases in England and Northern Ireland.
This calculator gives an estimate for residential SDLT only and does not cover every special case or relief.
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.
Estimate your borrowing power based on income, commitments, and lender income multiples.
This is a rough borrowing estimate only. Real lenders also consider credit history, dependants, deposit size, expenses, and affordability stress testing.
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.
See how overpaying your mortgage could reduce your term and save interest.
This is an estimate for a repayment mortgage. Real mortgages can include fees, overpayment limits, and lender-specific conditions.
This mortgage overpayment calculator estimates how making extra monthly payments could reduce your mortgage term and lower the total interest you pay over time.
It first works out your standard monthly repayment using your loan amount, interest rate, and mortgage term. It then adds your chosen monthly overpayment and simulates how much faster the loan balance would be cleared.
The calculator shows the difference between the original mortgage and the overpayment scenario, including the estimated interest saved and the amount of time taken off the mortgage.
Compare your current mortgage with a new deal and estimate your potential savings.
This is an estimate only. Actual remortgage savings can vary depending on fees, early repayment charges, lender criteria, and whether a new term is taken.
This remortgage calculator helps you compare your current mortgage deal with a new interest rate to estimate whether switching could reduce your monthly payment.
It calculates your current monthly repayment and compares it against a new repayment based on the same remaining balance and term, but using your proposed new rate.
The calculator also factors in remortgage fees and estimates how much you could save over your chosen deal period, along with how long it may take to recover the upfront costs.
Estimate how your savings or investments could grow over time with compound interest.
This calculator is an estimate only and does not include tax, fees, inflation, or investment risk.
This compound interest calculator estimates how savings or investments could grow over time when interest is earned on both the original amount and previously earned interest.
The calculation includes your starting balance, monthly contributions, annual interest rate, investment period, and how often interest is compounded.
Over time, compounding allows investment growth to accelerate because each period's interest is added to the balance before the next interest calculation.
Estimate your monthly loan repayments, total interest, and full repayment cost.
This calculator gives an estimate using a standard fixed monthly repayment formula. It does not include fees, penalties, or variable rate changes.
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.
Estimate your annual and monthly take-home pay for the 2025/26 UK tax year.
This is a simple payroll-style estimate for 2025/26. Pension is treated as a pre-tax deduction for this calculator, and it does not include benefits, tax code changes, or salary sacrifice edge cases.
This salary after tax calculator estimates your take-home pay by starting with your gross annual salary and subtracting deductions such as income tax, National Insurance, pension contributions, and student loan repayments where applicable.
It is designed to give you a quick estimate of how much of your salary you may actually keep after the most common payroll deductions are taken off.
The calculator also breaks the result down into annual, monthly, and weekly take-home figures so you can get a clearer picture of your income.
Estimate how your savings could grow over time with regular contributions and interest.
This is an estimate only. Real savings growth can differ due to changing interest rates, tax, fees, and account rules.
This savings calculator estimates how your money could grow over time based on a starting balance, regular monthly contributions, interest rate, and savings period.
It works by adding your monthly savings contributions and applying compound interest over the number of years you enter.
The calculator shows your estimated final balance, how much you personally contributed, and how much of the total comes from interest earned over time.
Estimate how long it could take to clear your credit card and how much interest you may pay.
This calculator gives an estimate only. Real card interest can vary depending on how your provider calculates interest, fees, promotional rates, and statement timing.
This credit card interest calculator estimates how long it could take to clear a balance based on your current balance, APR, and monthly repayment amount.
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.
Estimate how inflation could affect the future buying power of your money over time.
This is an estimate only. Real inflation changes over time, so this calculator is best used as a simple projection rather than a forecast.
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.
Quickly add VAT, remove VAT, and calculate the VAT amount from a price.
This calculator gives a simple VAT estimate based on the amount and rate you enter.
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.
Quickly work out percentages, percentage increases, decreases, and reverse percentages.
Use this calculator to find what percentage one number is of another, or to work out percentage changes.
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.
Quickly work out sale prices, discount amounts, and how much you save on a purchase.
Enter the original price and discount percentage to see the sale price and total saving.
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.
Calculate return on investment, profit, and ROI percentage from your investment.
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.
Work out how many units you need to sell to cover costs and reach a target profit.
Enter your fixed costs, selling price, and variable cost per unit to see your break-even point.
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.
Work out profit, profit margin, markup, and total profit from your cost and selling price.
Enter your cost price, selling price, and quantity to calculate profit margin, markup, and total profit.
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.
Estimate your new salary and see how much a pay rise adds per year, month, and week.
Enter your current salary and pay rise percentage to see your new salary and how much extra you could earn.
This pay rise calculator estimates how much your salary could increase after a percentage pay rise, a fixed annual increase, or a combination of both. It shows your new annual salary along with the extra amount per year, month, and week.
The percentage increase is calculated from your current salary. Any optional fixed increase is then added on top, giving you a total annual uplift and a new salary estimate.
This makes the calculator useful for checking job offers, annual reviews, promotion increases, union deals, and general salary planning.
Estimate how much house you may be able to afford based on income, debts, deposit, and mortgage assumptions.
This estimate combines an income-based borrowing approach with a simple mortgage payment stress check.
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.
A simple free online calculator for quick everyday maths.
You can also use your keyboard to type numbers and operators.
This calculator is a simple online tool for quick everyday maths. You can use it for addition, subtraction, multiplication, division, percentages, and decimal calculations.
Type numbers and operators using the on-screen buttons or your keyboard. The calculator updates as you go and gives you a quick result when you press equals.
It is designed to be fast, clear, and easy to use on desktop and mobile, making it useful for shopping, budgeting, homework, work tasks, and general number checking.
Work out tips, split bills, and adjust your tip based on service satisfaction.
Use the satisfaction slider for a suggested tip, or enter your own custom tip percentage.
This tip calculator helps you work out how much tip to leave on a bill, how much the total comes to, and how much each person should pay when splitting the cost.
You can use the service satisfaction slider to choose a suggested tip level, or type your own tip percentage manually if you already know what you want to leave.
There is also an optional round-up feature, which increases the tip slightly so the final bill becomes a neat whole-pound total.
Calculate exact age in years, months, days, hours, and time until the next birthday.
Enter a date of birth and comparison date to calculate exact age and time until the next birthday.
This age calculator works out exact age from a date of birth to a chosen comparison date. It can show age in years, months, and days, along with totals like months, weeks, days, and hours.
You can also include an optional birth time and comparison time for a more precise calculation. That makes it useful for babies, official records, milestones, and exact age checks at specific times of day.
In addition to the main age result, the calculator also shows the day of the week you were born, your next birthday date, and how many days remain until that birthday.
Compare products to see which one gives the best value per unit.
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.
Split a bill between friends and include tip or service charge.
This split bill calculator helps you divide a bill between multiple people quickly and clearly. It can also include an optional tip and service charge, so everyone can see what they owe once extras have been added.
You start by entering the original bill amount and the number of people sharing the cost. You can then add a tip percentage, a service charge percentage, or both.
The calculator adds those amounts onto the bill, works out the final total, and then divides everything equally to show the amount each person should pay.
Estimate fuel used, trip cost, and running costs based on distance, fuel price, and efficiency.
Choose miles + MPG or kilometres + litres per 100km to match your vehicle and trip details.
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.
Calculate running or walking pace, speed, and projected race times from distance and time.
Enter a distance and time to calculate average pace, speed, and estimated race times.
This pace calculator helps you work out your average pace, average speed, and projected race times based on the distance you covered and how long it took.
You can enter distance in either kilometres or miles, then add the total time in hours, minutes, and seconds. The calculator uses that information to estimate your pace per kilometre and per mile.
It also projects what the same pace would look like over standard distances like 5K, 10K, a half marathon, and a marathon, which makes it useful for training, goal setting, and race planning.
Calculate BMI using metric, imperial, or mixed measurements and view the standard BMI category range.
BMI is a simple screening measure based on height and weight. It does not directly measure body fat, health, or fitness.
This BMI calculator estimates body mass index using height and weight. BMI is a simple formula that compares weight with height to place the result into a standard category range.
You can use either metric or imperial measurements. In metric mode, enter height in centimetres and weight in kilograms. In imperial mode, enter height in feet and inches, and weight in stones and pounds.
The calculator also estimates a standard healthy weight range for the height entered. BMI can be a useful screening tool, but it does not directly measure body fat, muscle mass, or overall health.
Convert length, weight, temperature, volume, speed, time, height, body weight, and fuel economy in one place.
Choose a converter type, enter a value, and select the units you want to convert between.
This unit converter hub brings multiple everyday converters into one place. Instead of creating separate sections for each measurement type, the converter uses top buttons and a dropdown menu to switch between different categories like length, weight, temperature, volume, speed, time, height, body weight, and fuel economy.
You choose the converter type, enter a value, and then select the unit you want to convert from and the unit you want to convert to. The result updates inside the same converter section, which keeps the page cleaner and easier to navigate.
This converter also supports deep links, so menu items can point straight to a specific converter state such as length, weight, or temperature while still using one shared section on the page.
Convert image formats now, with resize, compress, and image to PDF tools ready to expand inside the same hub.
Upload a JPG, PNG, or WebP image and choose the format you want to convert it into.
Upload an image, enter new dimensions, and keep aspect ratio locked if you want the image proportions to stay consistent.
Compress an image by lowering quality and exporting it as JPG or WebP for smaller file sizes.
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.
Calculate the exact difference between two dates in days, weeks, months, and years.
This calculator gives the calendar difference between two dates and also shows the total number of days and weeks.
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.
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.
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.
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.
If you enter the later date first, the calculator automatically reorders the dates and still gives you the correct result.
The calculator uses real calendar dates, so leap years and varying month lengths are taken into account automatically.
Here are a few common examples showing how the calculator can be used for everyday date calculations.
Count working days between two dates or add business days, with UK bank holiday support.
This calculator can use weekends only, or weekends plus official UK bank holidays, depending on your settings.
This calculator helps you count working days between two dates or calculate a future date by adding a number of business days. It can exclude weekends and, if you choose, official UK bank holidays for England and Wales, Scotland, or Northern Ireland.
It is useful for contracts, payroll, project planning, shipping estimates, HR timelines, notice periods, and any situation where only working days should be counted.
In count mode, the calculator works out how many qualifying working days fall between the start date and end date. In add mode, it finds the resulting future date after adding a chosen number of business days to the start date.
A business day is normally a weekday. If you switch on bank holiday exclusion, official UK bank holidays for the selected region are also removed from the count.
With “Skip weekends” turned on, Saturdays and Sundays are excluded. If you turn it off, all seven days of the week can be counted unless excluded by another setting.
Different parts of the UK have different holiday calendars. This calculator lets you choose England and Wales, Scotland, or Northern Ireland for more accurate results.
Use count mode to measure the number of working days between two dates. Use add mode to calculate the final date after a set number of business days has passed.
Here are some common examples showing how the calculator can be used for work schedules, deadlines, and date planning.
Calculate hours worked, paid hours, and estimated pay for a shift.
This calculator estimates worked time and pay based on your shift times, unpaid break, and hourly rate.
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.
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.
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.
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.
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.
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.
Here are a few common examples showing how the calculator can be used for shifts, breaks, and pay estimates.
Count words, characters, sentences, paragraphs, and estimated reading time.
This tool updates live as you type and gives quick text statistics for writing, editing, study, and SEO work.
This word counter quickly analyses your text and shows useful writing statistics such as word count, character count, sentence count, paragraph count, and estimated reading and speaking time.
It is useful for essays, blog posts, SEO content, social captions, application forms, product descriptions, and any writing task where text length matters.
The calculator updates live as you type or paste text. It counts visible text content, removes spaces when needed for the “characters without spaces” result, and estimates reading and speaking time using standard average speeds.
Words are counted from normal text content, including most contractions and standard punctuation patterns. This makes the result useful for everyday writing and editing tasks.
Character count includes everything in the text box. Characters without spaces removes whitespace so you can measure the length of the actual text content more precisely.
Reading time is estimated from a typical silent reading speed, while speaking time is based on a slower spoken pace. These are practical estimates rather than exact timings.
Writers, students, marketers, and editors often need quick text stats without opening a document editor. This tool gives those numbers instantly in one place.
Here are a few common examples showing how a word counter can help with writing, editing, and content planning.
Count characters, words, sentences, and text length instantly.
This character counter measures the total length of your text and shows useful related statistics such as characters without spaces, words, sentences, paragraphs, and line count.
It is especially useful when you need to stay within text limits for social posts, forms, ads, meta descriptions, titles, captions, product descriptions, and other short-form writing.
The calculator updates live as you type or paste text. It counts all characters in the text box, and it also gives a separate count that ignores spaces so you can measure only the visible text content.
This count includes letters, numbers, punctuation, spaces, and line breaks. It is useful when a platform or form has a total character limit for everything entered.
This count removes spaces and other whitespace. It is helpful when you want to measure the actual text content only, without formatting gaps.
Line count can be useful for poetry, song lyrics, scripts, notes, code snippets, and any text where the number of lines matters as much as total length.
Although this tool focuses on characters first, it also shows word count and estimated reading time so you can understand both the size and readability of the text.
Here are a few common examples showing how a character counter can help with everyday writing and editing.
Convert live reference exchange rates between major currencies.
Reference-rate converter for planning and comparison. Final bank, card, or transfer rates may differ.
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.
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.
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.
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.
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.
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.
Here are a few common examples showing how a currency converter can be used for travel, budgeting, and price comparisons.
Create strong random passwords or memorable passphrases instantly.
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.
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 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 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.
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.
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.
Here are a few common ways to use random password mode and passphrase mode for different types of accounts.
Generate one or more random numbers instantly for games, draws, decisions, and everyday use.
Use this tool for random picks, prize draws, classroom activities, games, and quick number selection.
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.
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.
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.
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-number mode is best for draws, games, and simple picks. Decimal mode is useful when you want a random value that includes fractional numbers.
Unique results are useful for raffle numbers, team picks, classroom selection, and other situations where the same result should not repeat.
Here are a few common examples showing how a random number generator can be used in everyday situations.
Choose a base colour and generate matching palettes with adjustable intensity.
The intensity slider controls how bold or subtle the generated palette feels.
This tool lets you choose a base colour, then generate matching colour sets that work well together. You can pick the palette type, adjust the intensity, and copy individual HEX values or the full palette.
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.
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.
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.
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.
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.
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.
Here are a few common examples showing how different palette styles can be used for branding, interfaces, and creative projects.
Check whether text and background colours have enough contrast for readable, accessible design.
Use this to test body text, headings, buttons, links, and interface colours before publishing a design.
This sample text helps you see whether your chosen colour combination is easy to read for body copy and interface content.
This contrast checker compares a text colour against a background colour and calculates how easy that combination is to read. It shows the contrast ratio and tells you whether the colour pair is likely to work for normal text, large text, and interface elements.
It is useful for websites, buttons, forms, apps, dashboards, banners, slides, and any design where text needs to stay readable against a coloured background.
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.
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.
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.
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.
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.
Here are a few common examples showing how contrast checking helps with websites, interfaces, and marketing graphics.
Create CSS gradients with multiple colour stops, custom angles, and quick presets.
Use this for backgrounds, hero sections, buttons, cards, posters, and CSS design work.
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.
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.
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 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.
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.
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.
Here are a few common examples showing how gradients can be used in websites, graphics, and interface design.
Create custom CSS box shadows with live preview, presets, and copy-ready code.
Use this for cards, buttons, modals, panels, images, and interface elements that need more depth.
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.
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.
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.
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.
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.
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.
Here are a few common examples showing how box shadows can be used in modern interfaces and visual layouts.
Paste a list of names and pick one or more at random for classrooms, teams, giveaways, and quick decisions.
Great for classroom calls, team assignments, raffles, giveaways, and choosing who goes first.
The random name picker selects one or more names from a list completely at random. You simply paste names into the list, choose how many to pick, and the tool will select names instantly.
It is useful for classrooms, raffles, giveaways, team assignments, group work, and any situation where you want a fair and unbiased random choice.
The picker works by shuffling the list and selecting names randomly. If no-repeat mode is enabled, each selected name will only appear once in the result set.

Generate breakfast, lunch, or dinner ideas with ingredients, quick method steps, and realistic meal variations.
Built for quick inspiration with realistic meal combinations like soups, sandwiches, bowls, pasta, traybakes, and more.
This healthy meal generator creates breakfast, lunch, and dinner ideas based on the preferences you choose. It combines meal type, dietary preference, goal, cook time, cuisine style, meal format, and protein preference to generate a realistic meal idea with ingredients and a simple method.
It is designed for quick inspiration rather than rigid meal plans. That makes it useful when you want to decide what to eat, use ingredient ideas, or find a healthier meal direction without scrolling through long recipes.
Instead of pulling from just a short fixed list, the generator works with meal formats such as bowls, wraps, soups, salads, pasta dishes, and traybakes. It also uses realistic ingredient variations like broccoli, broccolini, rice, potatoes, roasted potatoes, chicken, tofu, lentils, and more.
Breakfast ideas stay breakfast-like, lunch ideas include things like soups, sandwiches, wraps, and salads, and dinner ideas lean toward bowls, roasts, pasta, and warmer cooked meals.
You can use the controls to push the generator toward high protein, lower calorie, quick meals, vegetarian options, vegan meals, or a preferred cuisine direction.
The include and avoid fields help guide the result further. This is useful when you want meals built around ingredients you already have or when you want to avoid something specific.
This tool is best for fast ideas, simple combinations, and meal inspiration. It is especially useful when you want a healthy direction without overcomplicating the decision.
Here are a few examples showing the kinds of meals this generator can create when different preferences are selected.

How it works
The Jack Tools Dice Roller is built for quick checks, combat turns, stat generation, encounter prep, and solo play. Pick the die, choose how many to roll, optionally drop the lowest result, and get a clear total with kept and dropped values separated automatically.
Each roll also generates a breakdown pill view and a staged total build-up so the result feels readable instead of abrupt. The result panel is especially useful for repeated dice checks on mobile, where the visual roll stage appears before the stats for a more natural scan order.

FAQ
Yes. Turn on Drop lowest and the lowest result is visually dimmed, excluded from the total, and listed separately in the dropped rolls area.
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.
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.
Dropped dice are intentionally dimmed so it is immediately obvious which values counted and which ones were excluded from the final total.
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.
Spin a premium name wheel with custom names, themed colourways, arrow styles, and controllable spin intensity.
Great for classrooms, giveaways, team picks, lucky draws, and fun visual decision making.
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.
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.
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.
It works well for classroom participation, giveaway winners, meeting order, chores, names in a hat, team picks, and many other quick decision-making tasks.
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.
The colourway and arrow style settings are visual only. They help the wheel feel more premium and themed, while the actual result stays random.
Here are a few common ways this tool can be used for selection, games, classrooms, and giveaways.
Upload an image, add captions, generate auto caption ideas, and export a meme-style image.
Auto caption ideas use your selected tone, caption format, and optional image context. They are suggestion-based, not image-reading AI.
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.
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.
You can upload an image, add text, and generate a simple finished meme quickly without leaving the page or using a separate graphics app.
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.
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.
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.
Here are a few common ways this meme generator can be used for jokes, reaction images, social posts, and quick visual captions.
