ROAS and break-even calculator for your numbers.

Find your break-even ROAS, your actual ROAS and whether your ads make or lose money after product cost, shipping, fees and returns.

What it does

Break-even ROAS equals 1 divided by your contribution margin. This calculator works it out from your selling price, product cost, shipping and fees and return rate, then compares it with the ROAS your ads actually deliver. Enter your own figures; the defaults are illustrations, not benchmarks, and nothing is sent anywhere.

Profit after ads, before overheads–

Fill in all six numbers.

How this is worked out
  • Revenue = orders × order value. Returned orders earn nothing and still cost shipping.
  • Contribution = kept orders × (order value − product cost − shipping and fees) − returned orders × shipping and fees.
  • Break-even ROAS = revenue ÷ contribution (the ROAS at which profit after ads is zero).
  • Overheads, the agency fee and tax are not included.

Illustrative arithmetic, not a forecast. Meta-reported purchase value can differ from store revenue.
