Profit Margin Calculator
Margin and markup from revenue and cost, both shown.

Gross profit

Margin (of revenue)
—
Markup (of cost)
Margin is profit ÷ revenue; markup is profit ÷ cost — two common-scaling ratios that give different numbers for the same deal (a 30% margin is a ~43% markup). Use the Markup Calculator for the reverse direction.
How to use the Profit Margin tool
- Enter your profit margin in the fields above.
- Adjust any slider or type an exact number — the answer updates as you go.

About the Profit Margin tool
Enter revenue and cost to see gross profit, margin (relative to revenue) and the equivalent markup (relative to cost) side by side.
Margin and markup are two names that get swapped constantly; showing both at once ends the confusion before it hits a pricing decision.
