Enter your profit margin and see the exact ROAS your ads need to break even, plus the target to actually profit. No signup, instant answer.
Break-even ROAS
2.50x
Below this, every sale loses money.
Target ROAS
4x
To keep 15% of revenue as profit.
At a 40% margin, your ads must clear 2.50x just to break even.
Break-even ROAS = 1 / gross margin. Target ROAS = 1 / (margin minus target profit). This is order-level math and excludes returns, shipping, and fixed overhead. See ROAS and AOV for definitions.
How break-even ROAS works
ROAS (return on ad spend) is revenue divided by ad spend. Break-even ROAS is the point where the revenue an ad drives exactly covers the product cost plus the ad cost. The formula is simple: break-even ROAS equals 1 divided by your gross profit margin. A 40% margin breaks even at 2.5, a 50% margin at 2.0, a 25% margin at 4.0.
To actually make money you need ROAS above break-even. To net a target profit margin on revenue, the required ROAS is 1 divided by (your gross margin minus that target). The calculator does both, so you know the floor to stay alive and the number to hit your goal.
Cheaper creative lowers the ROAS you need, because more of every sale stays as profit. Testing more ad variants at a low cost per video is how ecom teams find creative that clears these targets. See the 2026 creative testing framework.
Frequently asked questions
What is break-even ROAS?
Break-even ROAS is the return on ad spend at which a campaign neither makes nor loses money on the order it drives. It equals 1 divided by your gross profit margin. At a 40% margin, break-even ROAS is 2.5, meaning every $1 of ad spend must return $2.50 in revenue to cover the product cost and the ad cost.
How do you calculate break-even ROAS?
Break-even ROAS equals 1 divided by gross margin. If your gross margin is 50% (0.5), break-even ROAS is 1 / 0.5 = 2.0. To profit, you need ROAS above break-even. To net a target profit margin p on revenue, the required ROAS is 1 divided by (gross margin minus p).
Why does a higher margin mean a lower break-even ROAS?
The more profit you keep per sale, the less revenue each ad dollar has to generate to cover costs. A 70% margin product breaks even at a ROAS of about 1.43, while a 25% margin product needs a ROAS of 4.0. High-margin products can sustain far more aggressive ad spend.
