Marketing ROI Calculator
Measure campaign return from spend and attributed revenue. Optionally add gross margin to see margin-based ROMI alongside revenue ROI, and compare your revenue : spend ratio to the brief’s good (5:1) and excellent (10:1) thresholds.

Optional. One click generates a short plain-English summary. The calculator and exports still work if this fails.
Formula (suite brief § C3): ROI = (revenue − spend) / spend; ROMI = (revenue × margin − spend) / spend when margin is provided. Benchmark line: 5:1 revenue ratio = good; 10:1 = excellent — cited from the suite brief, not invented third-party statistics.
Frequently asked questions
- How is marketing ROI calculated?
- Revenue ROI = (attributed revenue − campaign spend) ÷ campaign spend. The revenue : spend ratio is revenue ÷ spend (for example 5 means 5:1).
- What is ROMI?
- ROMI (return on marketing investment) here applies your gross margin: (revenue × margin − spend) ÷ spend. Enable the margin input to see both revenue ROI and ROMI side by side.
- What revenue : spend ratio is considered good?
- The Marketing & AEO Tool Suite brief (§ C3) treats 5:1 as good and 10:1 as excellent. These are brief rule-of-thumb thresholds, not a guarantee for your channel mix. Source: https://docs.google.com/document/d/1qo2OTZnD_qlI-MrLuNjeiW6QaNXmBScoGpN6ruCjMlc/edit
