How to use this calculator
Enter visitors, a baseline rate, a scenario rate, revenue per conversion and contribution margin for the same period.
Formula and method
Expected incremental conversions = visitors×(scenario rate−baseline rate). Relative uplift = (scenario−baseline)/baseline.
Worked example
10,000 visitors moving from 2% to 2.5% gives 50 extra expected conversions, a 0.5 percentage-point or 25% relative increase.
Assumptions and supported scope
Scenario arithmetic, not an experiment or forecast. Relative uplift is undefined at zero baseline.
