The Marketing ROI Calculator measures campaign economics after gross margin instead of stopping at revenue ROAS.
Marketing ROI formula used here
The calculator estimates attributable gross profit as revenue multiplied by gross margin. It then subtracts marketing spend and divides the remaining contribution by marketing spend. That produces a gross-profit ROI rather than a revenue-only return.
ROI, ROAS, CPL and CAC answer different questions
ROAS compares revenue with ad or marketing spend. CPL shows what each lead cost. CAC shows what each acquired customer cost. Gross-profit ROI asks whether the gross profit generated by the attributed revenue actually exceeded the marketing investment.
Why gross margin changes the answer
A campaign can show a strong revenue ROAS and still lose money when the business has thin margins. The break-even revenue result shows how much attributed revenue is required, at the supplied margin, simply to cover the marketing spend.
Use attribution with discipline
The calculator only knows the revenue you enter. If attribution double-counts customers, ignores offline sales, or gives all credit to the final click, the economics will inherit that error. Use the cleanest attribution window your business can support.

Frequently asked questions
Is ROAS the same as ROI?
No. ROAS is usually revenue divided by advertising spend. ROI considers profit or contribution after cost.
What if my campaign has zero tracked customers?
CAC and close rate cannot be meaningful until customer conversions are tracked. Fix measurement before drawing performance conclusions.
