Returns are applied to revenue and to recoverable goods cost, which is why a high return rate moves the break-even point so sharply. This is arithmetic, not advice — your accountant has the final word on what counts as a cost.

How to read the result

Break-even ROAS is where ad spend exactly equals gross profit. Below it you are buying customers at a loss; above it you are making money, before fixed costs.

If your break-even is above 4x, paid traffic is going to be hard. That is not a bidding problem — it is a pricing, cost or product problem, and no agency can fix it with a target.

Returns move this more than people expect. A 30% return rate on a fashion product can push a comfortable 2.5x break-even to something you will struggle to hit consistently.

The "max CPA" line is often the more useful number day to day: it is what one order may cost you in ad spend before you stop making money, and it translates directly into a bidding target.
