Marketing ROI Calculator

Quick answer: Marketing ROI compares profit from attributed revenue to media spend. Pair it with cash-flow timing when campaigns pay back over uneven periods.

How this differs from blended ROAS

Return on ad spend (ROAS) divides revenue by spend without subtracting cost of goods. This tool uses simple profit (revenue minus spend) for a ROAS vs ROI-style lens before overhead.

Frequently asked questions

What does this marketing ROI calculator measure?

It divides profit (attributed revenue minus ad spend) by ad spend and expresses the result as a percentage. It is a single-period snapshot—use the same definition of “revenue” across campaigns when comparing results.

How should I treat revenue attribution?

Use the revenue your team agrees is driven by the spend in question (last-touch, modeled, or holdout—be consistent). Mixing attribution rules across rows makes ROI incomparable even when the math is correct.

When is marketing ROI misleading?

When lifetime value is omitted, when organic and paid overlap is ignored, or when returns arrive quarters later—simple ROI ignores timing. In those cases pair with payback or NPV-style thinking.
