Real Return = (1 + Nominal) / (1 + Inflation) - 1

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter your nominal (stated) investment return rate.
2Enter the inflation rate over the same period.
3Optionally enter a principal amount and time period to see dollar impacts.
4The calculator applies the Fisher equation to find the real return.

Examples

10% return with 3% inflation over 5 years on $10,000

1.Real return = (1.10/1.03) - 1 = 6.80%
2.Nominal FV = $10,000(1.10)^5 = $16,105
3.Real FV = $10,000(1.068)^5 = $13,896
4.Inflation ate $2,209 of purchasing power

Result: 6.80%
