Method & formula
ROAS divides revenue attributed to advertising by the ad spend for the same scope and period. A ROAS of 5× means five units of revenue were attributed for every one unit spent on advertising.
- ROAS = attributed revenue ÷ ad spend
Example
5,000 of attributed revenue from 1,000 of ad spend gives a ROAS of 5.00×.
FAQ
Is ROAS the same as profit?
No. ROAS ignores product cost, fulfilment, payment fees, returns and other costs. Use Break-even ROAS when you need to connect advertising performance to unit economics.
What happens when ad spend is zero?
ROAS cannot be calculated because there is no non-zero spend denominator.
