Marketing ROI calculator
Calculate attributed return with and without baseline revenue.
Compare standard marketing ROI with an incremental view that removes revenue the business expected without the selected spend.
Where the work changes.
Treat the output as a decision input
A calculator makes assumptions visible. It does not replace attribution quality, margin context or direct account review.
Questions before the audit.
- What is baseline revenue?
- It is the revenue expected without the selected marketing spend. Use a documented method rather than inserting a number only to improve the result.
- Can incremental ROI be negative?
- Yes. A negative result means the selected attributed revenue did not cover baseline revenue plus marketing spend under this definition.
- How is marketing ROI different from ROAS?
- ROAS compares attributed revenue with ad spend. Marketing ROI subtracts spend and can include a baseline adjustment.
Calculate from your numbers.
Standard ROI subtracts spend from attributed revenue, then divides by spend. Incremental ROI also subtracts baseline revenue. Revenue per dollar divides attributed revenue by spend.
Review the return model behind budget decisions.
We will compare the attributed result with the measurement and baseline evidence available today.
