How to use this calculator
- Enter the known values in the units shown. Results update as you type.
- Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
- Use the worked example to check the method. Reset restores the starting fields.
Use the result with context
Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.
Formula and method
In the one-year example, modeled benefit of 5,000 against cost of 1,000 gives net ROI of 400%.
ROI (%) = 100 × (total modeled benefits − total modeled cost) / total modeled cost.
Worked example
Enter these known values and leave the other values blank.

Assumptions and limitations
- Productivity benefit assumes the entered fraction of employee cost is recoverable value. Time saved does not automatically become cash savings.
- Churn improvement and profit-margin improvement inputs are relative percentage reductions or increases, not percentage-point changes. Include only attributable benefits and avoid double counting.
- Annual ROI divides cumulative ROI by years; it is a simple arithmetic average, not a compounded annual return or discounted cash-flow result.
- Enter all money amounts in one currency. The retained currency conversion menu uses captured historical conversion factors, not current exchange quotes.
- Clear an unknown editable field before solving an inverse; fixed selections and output-only fields cannot be inferred.
Common questions
What does this calculation assume?
Productivity benefit assumes the entered fraction of employee cost is recoverable value. Time saved does not automatically become cash savings.
Are these current exchange rates?
No. Use one currency consistently; currency menu factors are a historical snapshot.
