Free ROAS calculator
Calculate reported return on ad spend as a multiple and percentage, with the value definition kept clear.
Try your own numbers.
The starting values are illustrative. Replace them with compatible numbers from your report.
This calculator divides attributed conversion value by advertising spend. Use the same currency for both inputs and describe what the value represents. The result can verify report arithmetic, but it cannot determine profit or the incremental effect of the advertising.
Work through it, step by step.
Check whether value represents order revenue, estimated lead value or another configured measure. Do not silently rename an estimated value as sales.
Enter compatible value and spend for the same account scope and period. Keep cross-platform attribution claims separate.
Read the multiple and percentage as two formats of the same ratio. Review broader business costs separately when evaluating commercial performance.
Make it concrete.
With 7,500 in attributed value and 2,500 in spend, reported ROAS is 3×, also expressed as 300%. A 3× ratio is not a 300% profit margin.
What to keep in mind.
Zero spend makes the ratio undefined. Refunds, fulfilment costs and overlapping platform credit can materially change the business interpretation.
Your next useful step.
Use the ROAS-versus-ROI comparison to choose the right calculation for the decision. Preserve the underlying value definition in every exported or shared summary.
