How to use this tool
- Enter nominal return, inflation.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Real return = [(1 + nominal return/100) ÷ (1 + inflation/100) − 1] × 100.
An 8% nominal return with 3% inflation corresponds to approximately 4.8544% real return.
What to keep in mind
Use return and inflation covering the same period. Taxes and fees are excluded unless reflected in nominal return; the inflation rate is user supplied.
Common questions
Can I just subtract inflation?
That is an approximation. The ratio formula accounts for compounding between the two percentage changes.
Can real return be negative?
Yes. Purchasing power falls when the nominal result does not keep pace with inflation.
