Inflation & buying power

Inflation reduces the goods and services a fixed amount of money can buy. This calculator expresses a future amount in today’s purchasing power by dividing the starting amount by (1 + inflation rate)^years. It keeps the nominal cash balance fixed and changes only its purchasing power.

For example, at 10% annual inflation, 110 units of money one year from now have the purchasing power of 100 units today. An inflation rate of zero leaves purchasing power unchanged. The rate is constant in this illustration; it is not a forecast or a live economic reading.

Personal spending can differ from a national consumer price index, especially when housing, education or healthcare make up a large share of expenses. A nominal investment return should not be confused with a real return after inflation. For comparable annual rates, the exact real-return relationship is (1 + nominal return) / (1 + inflation) − 1. This page illustrates purchasing power only and does not combine an investment portfolio with inflation.
