TOOLS / MARKETING ROI CALCULATOR
Marketing ROI Calculator
A transparent working model for planning. It does not replace reliable business data or an individual analysis.
How to interpret the result
ROI = (attributable contribution − marketing cost) / marketing cost × 100. Enter contribution before deducting the marketing costs used here.
Use the result as a starting point for discussion. Check assumptions and turn data gaps into explicit tasks. This tool does not send your entries to a server.
Frequently asked questions
How does this marketing ROI calculator work?
The formula is (value minus cost) divided by cost, multiplied by 100. Define whether value means revenue, contribution margin or another measure. The result is meaningful only with consistent assumptions.
Are my inputs stored or transmitted?
No. This tool calculates the result locally in your browser and does not persist your inputs.
Does the result replace expert review?
No. Review inputs, period and assumptions. The result is a starting point. Individual interpretation can form part of the relevant marketing consulting service.
How do I assess whether a marketing calculator or self-check is meaningful?
First check whether inputs, time period and calculation logic fit your decision. Record estimates and missing information, then test how different assumptions change the result. A calculated number or score is a starting point, not an industry benchmark or proof of impact.
What should I do after an unexpected result?
Review the inputs and stated assumptions before deciding what to change. Work with the relevant owners to distinguish a data error, an incomplete baseline and an actual bottleneck. Then prioritise a next task that can be checked.
