What is the Break-even ROAS Calculator?
Break-even ROAS is the return on ad spend at which advertising neither makes nor loses money. Formula: break-even ROAS = 1 ÷ contribution margin, where contribution margin = (order value − product, shipping, fees and other variable costs) ÷ order value. A product with a 40% contribution margin needs a ROAS of at least 2.5×.

Frequently asked questions
Is break-even ROAS the same as target ROAS?
No. Break-even is the minimum; target ROAS is higher so you also make the profit you want.
Why is my ROAS positive but I still lose money?
Because ROAS counts revenue, not profit. With a 30% margin, a 2× ROAS still loses money.
