How this calculator works
Enter the revenue your reporting attributes to marketing and the total cost of generating it. The calculator returns the percentage return above that cost, plus the net gain in dollars.
The formula
Marketing ROI = (Revenue attributable to marketing − Marketing cost) ÷ Marketing cost × 100. Because it subtracts the cost first, a 0% ROI means you exactly broke even, not that you made nothing back.
Worked example
Attribute $120,000 of revenue to marketing that cost $30,000 all in, and ROI is 300% — three dollars of gain for every dollar invested.
How to read your result
Note this uses revenue, not gross profit. At a 30% margin, a 300% revenue ROI is a much thinner result than it appears. If your margins are slim, run the same calculation on gross profit for the truer figure.
Questions
What should I include in marketing cost?
Media spend, agency or staff cost, software, and production. If you would not spend it when marketing stops, include it.
How is this different from ROAS?
ROAS divides revenue by media spend only and does not subtract the cost. ROI includes every cost and reports the gain above it.
What counts as attributable revenue?
Revenue your analytics or CRM can connect to marketing activity. Be conservative — inflating attribution is the fastest way to a flattering, useless number.
