ROAS Calculator
Turn campaign spend and attributed revenue into a decision-ready ROAS. Add gross margin to see whether a campaign that looks efficient is actually above its break-even point.
iCurrency-neutral: use the same currency for spend and revenue.
Use it without guessing.
- 01Enter ad spend and attributed revenue.
- 02Add your gross margin for a break-even check.
- 03Compare actual ROAS with break-even ROAS before scaling.
What the number means
ROAS equals attributed revenue divided by ad spend. A 4.0× ROAS means every $1 of media spend generated $4 in attributed revenue.
Revenue is not profit. If your gross margin is 25%, your break-even ROAS is 4.0× before overhead, returns and payment fees. Attribution settings also change the reported revenue, so compare campaigns using the same window and model.
Before you rely on the output
What is a good ROAS?+
There is no universal target. Your break-even point depends on gross margin, fulfilment costs, overhead and the share of sales that would have happened without advertising.
How is break-even ROAS calculated?+
The simplified formula is 1 divided by gross margin expressed as a decimal. At a 40% margin, break-even ROAS is 1 / 0.40 = 2.5× before other variable costs.
