UNDERSTAND BEFORE YOU DECIDE

What the number can—and cannot—tell you.

01

ROAS measures revenue efficiency

A 4.2× ROAS means the attribution method assigned 4.2 currency units of revenue for each currency unit of advertising spend.

02

ROAS is not profit or ROI

It does not automatically account for product cost, salaries, fees, returns, overhead or the reliability of attribution.

This educational calculation depends on the spend and attributed revenue you enter and is not business or financial advice.
