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 profit 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 figures are related, but they are not the same, which is why many businesses use both when reviewing pricing.

By including quantity sold, this calculator also estimates total cost, total revenue, and total profit. That makes it useful for retail, ecommerce, wholesale, freelancing, and service pricing decisions.

It can also help when checking whether a current selling price is sustainable, testing a new price point, or comparing how pricing changes affect overall profitability.

Profit Margin Calculator FAQs

Margin is based on selling price, while markup is based on cost price. They measure profitability from different starting points, so the percentages are usually different.
Profit margin is calculated by dividing profit per unit by selling price and 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, ecommerce sellers, freelancers, service businesses, and anyone setting prices or reviewing product profitability.
A 50% markup means your profit is equal to half of your cost price. For example, if something costs £100 and you apply a 50% markup, the selling price becomes £150.
