Work out margin, markup, profit & selling price instantly
Our free profit margin calculator works out your gross margin, markup percentage, profit and recommended selling price. Enter any two of cost, revenue or margin and it calculates the rest — essential for pricing products, running a business, or working out your profit on a sale. Includes a clear explanation of margin vs markup.
Enter cost and selling price → see margin & markup. Or fill cost + a target below to find the price.

They use the same profit but a different base. Margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost. Example: buy at £40, sell at £100 → profit is £60. That's a 60% margin (£60 ÷ £100) but a 150% markup (£60 ÷ £40).
Gross margin % = ((Selling price − Cost) ÷ Selling price) × 100. Enter your cost and selling price above and the calculator shows margin, markup and profit instantly.
To achieve a target margin, divide your cost by (1 − margin). For a 50% margin on a £40 item: £40 ÷ (1 − 0.5) = £80. Use the "Find the Selling Price" section above and set Type to Margin.
No — margin can never reach 100% (that would mean zero cost) since it's profit as a share of the selling price. Markup, however, can exceed 100% easily — a 150% markup just means you're selling for 2.5× what it cost you.
