How do I calculate ROAS across campaigns?
Enter total ad spend and total attributed revenue instead of averaging individual ROAS percentages. This example assumes the same period and currency, with no duplicated revenue between campaigns.
| Campaign | Ad spend (USD) | Attributed revenue (USD) | ROAS |
|---|---|---|---|
| A | 100 | 500 | 500% |
| B | 900 | 900 | 100% |
| Total | 1,000 | 1,400 | 140% |
Enter spend 1000 and revenue 1400 to get 140%, or 1.4×. The simple average (500% + 100%) ÷ 2 = 300% is not the combined ROAS because spend differs. This tool has no campaign-list aggregation feature; total the inputs first. Check that the same revenue is not counted in multiple advertising reports. ROAS is not a profit margin and does not deduct product costs or fees.
Compare relative changes with the percentage calculatorHow 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.
How it works
ROAS (%) = ad-attributed revenue ÷ ad spend × 100. The ratio is revenue ÷ spend. ROAS is undefined when spend is zero.
Common questions
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.
Can revenue be zero?
Yes. Positive spend with zero attributed revenue gives 0% ROAS. Zero spend cannot be used as the denominator.
Does changing currency convert the amounts?
No. The currency selector is for display only. Convert spend and revenue to the same currency before entering them; dividing amounts in different currencies does not produce a comparable ROAS.
