ROAS Calculator Frequently Asked Questions
It divides attributed revenue or conversion value by advertising cost. The tool also shows the same ROAS as a percentage, revenue per $1 spent, and optional target-revenue outputs.
Enter advertising cost and attributed revenue from the same reporting scope. For example, $15,000 of attributed revenue divided by $5,000 of ad spend equals 3.0x ROAS, or 300%.
Yes. A 4.0x return on ad spend means $4 of attributed value for every $1 of advertising cost. Multiplying 4.0 by 100 expresses the same ratio as 400%.
This calculator accepts the target as a multiple. Enter 5.0x for a Google Ads target shown as 500%, 3.5x for 350%, and so on.
No. The revenue-less-spend output excludes product costs, service delivery, payment fees, refunds, overhead and other expenses. Use ROAS as an advertising value-efficiency ratio, then use the appropriate ROI or break-even calculator for profit context.
Use the closest metric for the decision you are making instead of combining every advertising ratio into one number.
