How it works

Three things ROAS tells you

01
What ROAS measures

ROAS is the revenue returned for every unit of currency spent on ads. A 4x ROAS means four dollars back for every dollar in. It says nothing about profitability on its own.

02
How break-even ROAS works

Break-even ROAS is the minimum return needed to cover product cost and ad spend. It is calculated from your margin: 1 divided by your margin percentage. Below it, ads are losing money.

03
Why margin changes everything

A 4x ROAS is profitable at 40% margin but unprofitable at 20%. The same campaign number means different things for different businesses. Margin is the context that makes ROAS meaningful.
