About the Profit Margin Calculator

The Profit Margin Calculator finds your profit and expresses it in two useful ways: profit margin and markup.

Profit is revenue minus cost. Profit margin is profit as a percentage of revenue, while markup is profit as a percentage of cost.

Margin and markup are often confused but always differ. For the same sale, margin is the smaller percentage. All maths runs in your browser.
