How to use

Gather ad spend and ad-attributed revenue for the same period.
Enter both amounts in the same currency, then calculate.
Read the percentage and revenue multiple. Currency selection changes the label; it does not convert money.

ROAS (%) = ad-attributed revenue ÷ ad spend × 100. The ratio is revenue ÷ spend. ROAS is undefined when spend is zero.

Does 1× ROAS mean I broke even?

Only revenue and ad spend are equal. Product costs, shipping and fees can still result in a loss.

Which revenue should I enter?

Use attributed revenue for the same reporting period and attribution window. Keep tax treatment consistent.

What is a good ROAS?

It depends on your costs and target profit. This calculator does not prescribe a universal profitable threshold.
