What is the marketing ROI formula?

Marketing ROI % = ((revenue - ad spend) / ad spend) x 100. For example, 5,000 spent on ads that generated 20,000 in attributed revenue gives a net of 15,000 and a marketing ROI of 300%. The return multiplier (ROAS) is 4x.

What is the difference between ROI and ROAS?

Return on ad spend (ROAS) is revenue divided by ad spend, expressed as a multiplier. ROI subtracts the spend first and expresses the net as a percentage of spend. A ROAS of 4x corresponds to an ROI of 300%.

Should I include other costs besides ad spend?

For a true profit ROI, include all campaign-related costs in the spend field: ad budget, creative production, agency fees, and any platform tooling. If you only include ad spend, the result is technically a media ROI.

Formula: Marketing ROI % = ((revenue - ad spend) / ad spend) x 100

How it works

Simple ROI uses the formula ROI % = ((gain - cost) / cost) x 100. Annualized ROI uses ((gain / cost)^(1 / years) - 1) x 100, which expresses total return as an equivalent constant per-year rate. Marketing ROI applies the same simple-ROI arithmetic to ad spend and attributed revenue, with the additional ROAS multiplier shown alongside the percentage.
