What this means

Inflation means the same money buys less over time. Savings earning less interest than prices rise lose buying power, even as the balance grows, so it’s worth checking your rate against inflation.

The consumer price index tracks the cost of a typical basket of goods and services. Your own costs can rise faster or slower, depending on what you spend on.

How the calculator works

Pick an amount and two years. The years run from 1988 to the September quarter of 2026.
The change in prices: the price index in the second year divided by the index in the first. Each year uses its yearly average, and the latest year its most recent figure.
The result: your amount multiplied by that change, with the average yearly rate that compounds to the same rise.

You can also go backwards, to see what today’s money would have bought in an earlier year.
