About ROAS
What is ROAS?
Return on Ad Spend. Revenue divided by ad spend, usually written as 4.0x or 4:1. Higher = more revenue per ad dollar.
ROAS vs ACOS
They’re inverses of each other. 4× ROAS = 25% ACOS. Amazon uses ACOS by convention; Meta and Google use ROAS. Same number, different angle.
Break-even ROAS
The minimum ROAS where you stop losing money on ad-driven sales. Calculated as 1 / gross margin. If your gross margin is 40%, you need 2.5x ROAS to break even. Anything below that and you’re subsidizing sales.
