Is your ad spend actually profitable?
ROAS measures revenue, not profit, so a "good" ROAS can still lose money once margin and incrementality are accounted for. Enter three numbers to see your real break-even ROAS and what's actually left after ad spend. No email, no signup.
How to read these numbers
Break-even ROAS = 1 ÷ gross margin. At a 60% margin, you need a 1.67× return on every ad dollar just to cover the cost of the goods you sold. Anything above that contributes profit; anything below quietly loses money even if the dashboard shows a "positive" ROAS.
Why ROAS alone misleads
ROAS is a revenue ratio, so it ignores margin entirely. A 4× ROAS on a 20% margin product is underwater (break-even is 5×), while a 2× ROAS on an 80% margin product is comfortably profitable (break-even 1.25×). Always compare current ROAS to your break-even, not a generic benchmark.
The incrementality gap
Ad platforms count conversions they touched, including buyers who'd have purchased anyway. If 20–40% of "attributed" revenue isn't incremental, your true break-even ROAS is meaningfully higher than the textbook formula. The advanced slider lets you stress-test that, and it's the single biggest reason rising ad spend stops turning into revenue, covered in Why your ad spend isn't turning into revenue.
Fixing this is core to paid media management and attribution & reporting, making the reported number match the real one.
Common questions
What is break-even ROAS?
Break-even ROAS is the return on ad spend at which your gross profit from advertising exactly equals what you spent, so you neither make nor lose money on the marginal sale. The formula is 1 ÷ gross margin. At a 60% gross margin, break-even ROAS is about 1.67, meaning every $1 of spend must return at least $1.67 in revenue just to break even.
Why is a 3x ROAS sometimes still unprofitable?
ROAS measures revenue, not profit. If your gross margin is thin, a high ROAS can still lose money once you account for cost of goods, and platform-reported ROAS often over-credits sales that would have happened anyway. The honest number is contribution after ad spend: revenue × margin − ad spend, ideally adjusted for incrementality.
What is the incrementality adjustment?
Some of the revenue an ad platform reports would have happened anyway (existing demand, brand searches, returning customers). The incrementality adjustment lets you discount that baseline so you measure the revenue the ads actually caused, which raises your true break-even ROAS.
