How it works
Adjust a nominal return for inflation over the same time period. Both rates are entered by you, not retrieved live.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Nominal return | 10 % | Enter the percentage as a number: for 15%, enter 15. Allowed range: -99–10,000. |
| Inflation | 4 % | Enter the percentage as a number: for 15%, enter 15. Allowed range: -99–10,000. |

Match the rate period to the payment period. Fees and taxes absent from the inputs are not added automatically; compare totals with the same cost coverage.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
