How it works

Profit = revenue − cost. Profit margin = profit ÷ revenue × 100 (share of the selling price kept as profit). Markup = profit ÷ cost × 100 (profit relative to what you paid).

Profit, margin, and markup

Profit is the money left after costs. Margin measures that profit against the selling price, while markup measures it against the cost. They answer different questions, and confusing them is a common pricing mistake — a 50% markup is only a 33% margin. This calculator shows all three together.

Frequently Asked Questions

Margin vs. markup — what's the difference?

Margin is profit divided by the selling price; markup is profit divided by the cost. The same profit gives a higher markup percentage than margin.

What if revenue is below cost?

Then the result is a net loss — the profit shown will be negative, signalling the sale lost money.
