Tool details and privacy
ROAS is revenue divided by spend. The margin is optional: it is taken from revenue, then the spend is subtracted.
It separates the ratio from profit after ads when you enter a margin.
Options
- The margin is a percentage of revenue, not of the spend. Leave it blank to show only the ratio.
Limits
- Amounts use two decimal places and up to 12 digits before the decimal point. Rounding is half up.
- 1,250 is rejected. Write 1250 or 1250.50.
- It does not fetch figures from an ad platform.

The numbers are calculated in your browser and are not sent to any server.
