About this calculator
Profit Margin is easiest to get wrong in the setup, not the arithmetic. It computes profit margin = (selling price − cost) ÷ selling price × 100. It matters whenever pay, prices or filings depend on getting the arithmetic right before the paperwork does. The worked example on this page (Selling at 250 with a 180 cost: profit 70, margin = 70 ÷ 250 × 100 = 28% .) shows the full substitution; the calculator above runs the same working on your own numbers, in your browser, with nothing uploaded.
How to use
- Enter the revenue or selling price.
- Enter the cost of the product or service.

FAQ
How does this profit margin calculator define margin?
Margin is profit divided by revenue, expressed as a percentage. Profit is revenue minus cost, so margin shows the share of revenue you keep.
Does the Profit Margin Calculator send my data to a server?
No. The Profit Margin Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Is margin the same as markup?
No. Margin is profit over revenue, while markup is profit over cost. The same profit gives a smaller margin than markup.
What is a healthy margin?
It varies widely by industry, so compare against typical figures for your sector rather than a single universal target.
