ROAS is only good news above break-even.
A 3x return sounds healthy until your margin says you needed 4x to stand still. This works out your break-even ROAS first, then tells you whether the campaign actually made money.

Reading the number honestly.

01
Break-even ROAS is 1 divided by your margin
At a 45% gross margin you need 1 ÷ 0.45 = 2.22x just to get your money back. At a 25% margin you need 4x. This is why one advertiser celebrates a 3x return and another is quietly losing money on the same number — the margin, not the ROAS, decides which.

02
ROAS ignores every cost that is not media
Platform fees, creative production, agency retainers, shipping and returns all sit outside the ROAS calculation. A campaign at exactly break-even ROAS has, in reality, lost money once those land. Treat break-even as the floor you must clear comfortably, not the target.

03
Attribution decides the revenue number, so question it
The revenue figure comes from whichever attribution window the platform used, and platforms are graded on their own homework. If Meta, Google and your own analytics all claim the same sale, the honest total is lower than the sum of the three dashboards.
