How to use this calculator

Choose a known pair among cost, revenue, profit and margin to calculate the remaining pricing measures. Trading modes separately estimate stock or currency margin collateral; they do not forecast returns or liquidation risk.

Enter what do you know?, product cost, selling price / revenue and review the remaining options.
Select Calculate or change a value to update the result. Read the result label and units before copying.

Formula and method

Margin = (revenue − cost) ÷ revenue × 100

Gross profit excludes costs not entered. Trading-margin calculations are arithmetic collateral estimates, not broker approval, maintenance calls, fees or investment advice.

Worked example

Cost 60 and revenue 100 give profit 40 and margin 40%.

Questions about profit margin calculator

Is 20% margin the same as 20% markup?

No. With cost 80 and selling price 100, profit is 20, margin is 20%, and markup is 25%. Use Margin when you know revenue and cost; use Markup when setting a selling price from cost and a markup rate.
