RoAS stands for Return on Ad Spend.
Last updated: June 2026
- RoAS — Return on Ad Spend
- RoAS (Return on Ad Spend) = ad revenue ÷ ad spend. It is the inverse of ACoS: a 4× RoAS is the same as a 25% ACoS. RoAS expresses ad efficiency as a multiple (“₹4 back for every ₹1 spent”) rather than a percentage.
In depth
RoAS and ACoS describe the same thing from opposite directions. RoAS = 1 ÷ ACoS. Many sellers and most non-Amazon ad platforms use RoAS; Amazon’s console defaults to ACoS. A higher RoAS is better (more revenue per ad rupee); a lower ACoS is better. Convert with: RoAS = 100 ÷ ACoS%.
