66.7%
- Revenue
- $5,000

- $3,000

ROI = (Revenue − Cost) ÷ Cost
- Revenue and cost are measured over the same time window.
- Cost includes all incremental costs you attribute to the initiative.
FAQ
Is ROI the same as ROAS?
No. ROAS is typically revenue divided by ad spend, while ROI uses profit (revenue minus cost) divided by cost.
How to interpret
How to interpret ROI
- ROI focuses on profit relative to cost; it’s stricter than ROAS.
- Use a consistent cost definition (include tools/labor if you decide to).
- Compare ROI across initiatives using the same timeframe.
Common pitfalls
- Leaving out ‘hidden’ costs like agency fees or salaries.
- Using lifetime revenue for some campaigns but not others.
- Comparing ROI with different attribution rules.
