Break-Even ROAS Calculator
Find the minimum ROAS (and maximum CPA) you can afford based on AOV, margin, fees, shipping, returns, and fixed overhead. Forecast profit across ROAS levels and export scenarios.
ROAS & CPA Break-Even Toolkit
Enter your unit economics once, then instantly see break-even ROAS, break-even CPA, and profitability at different ROAS levels.
Tip: If you track blended efficiency, compare your break-even ROAS to your MER (total revenue ÷ total marketing spend). If MER is below break-even, you’re likely losing money overall.
Enter your numbers in “Break-even ROAS” first, then use this tab to explore CPAs and implied ROAS from an expected conversion value.
Tip: If you know your target ROAS, you can reverse it into an allowable CPA: allowable CPA = AOV ÷ target ROAS.
Tip: Forecasts are only as good as inputs. If your attribution window differs from your cashflow window, consider using blended revenue or a conservative ROAS.
Generate scenarios to see how profit changes as ROAS moves up or down. Use Export CSV to copy into a spreadsheet.
