🚀 ROAS Calculator
ROAS tells you how much revenue each dollar of advertising brings back. Comparing it with your break-even ROAS shows whether ads actually make a profit.
How the ROAS Calculator works
Revenue from ads is divided by ad spend. Break-even ROAS is 1 ÷ gross margin: below it, the gross profit from ad sales does not cover the ads.
Step-by-step calculation
- 1Enter revenue from ads.
- 2Enter ad spend.
- 3Divide revenue by spend; compare with break-even ROAS.
Worked example
$12,000 of revenue from $3,000 of ads is a 4.0x ROAS (400%). With a 40% margin, break-even ROAS is 2.5x and profit after ads is $1,800.
