Frequently asked questions
What does the calculation include?
Cost per conversion divides spend by the conversion count; return on ad spend divides attributed revenue by ad spend. Revenue minus ad spend is before product, fulfilment, tax, and other costs, so it is not profit. Use a consistent campaign definition, attribution, reporting period, and currency.
Which values should I enter?
Calculate cost per conversion and return on ad spend from campaign totals. Use consistent amounts, units, and time periods.
Is the result definitive?
No. Check the assumptions and rules that apply to your situation; this is an illustrative calculation, not professional advice.
