Inflation Rate Calculator – Track the Real Value of Money in 2026

About this Real Value Of Money Calculator

This real value of money calculator converts an amount from one year into its equivalent value in another, using official consumer price index data. Enter the amount and the two years, and the result shows the equivalent figure, the total cumulative inflation between them, and the average annual rate that produces the same change.

How the calculation works

The equivalent value equals your original amount multiplied by the ending year price index, then divided by the starting year index. Because inflation compounds, the average annual rate is always lower than the total change divided by the number of years.

Reading the result correctly

Prices rising is not the same as money losing value

If prices rise 25%, money does not lose 25% of its value, it loses 20%. Purchasing power is the starting index divided by the ending index, which is not the mirror image of the inflation percentage.

Averages are not personal

A consumer price index measures a fixed national basket. Your own experience depends on what you buy and where you live, so your personal rate can differ from the published figure.
