01
How to use it
Enter attributed revenue and the contribution margin before campaign costs. Add ads, software and working time for the same reporting period. All amounts must use one currency.
02
A practical example
For revenue of 5,000, margin of 60%, ads of 500, tools of 100 and 10 hours at 40, total campaign cost is 1,000. Net contribution is 2,000 and ROI is 200%.
03
Limits and interpretation
Revenue attribution is an assumption you enter. This calculator cannot decide whether social media caused a sale. Avoid counting the same cost in both margin and campaign spend.
04
Your next step
Build tagged links with the UTM builder, then compare campaigns using the same period and attribution method.
