Enter your orders and average order value, or load the sample data, to see your profit breakdown.

An estimate for planning, not accounting advice. Product and fulfilment costs are applied to every order, including refunded ones.

Gross sales = orders × AOV. Net sales = gross − returns. Contribution before ads = net − product − fulfilment − fees. Operating profit = contribution after ads − other costs. Break-even ROAS = gross sales ÷ contribution before ads, because ad platforms report gross attributed revenue.
