How to use the profit margin calculator.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. Profit = sale − cost. Margin = profit ÷ sale. Markup = profit ÷ cost. Cost ratio = cost ÷ sale.

Try a worked example

A £60 cost sold for £100 produces £40 profit, 40% margin and 66.67% markup.

Check the assumptions

This is gross profit before overheads, tax, payment fees, returns and other costs.
