Inflation calculator Australia
Prices change over time. This calculator tells you what an amount from the past is worth in today's dollars, using the official Consumer Price Index (CPI).
Enter the amount and the two dates. The calculator uses the CPI of each quarter, from the March quarter 2000 to the latest one published.
How it's calculated
- Each date is matched to its quarter of the year.
- The amount is multiplied by the CPI of the final quarter and divided by the CPI of the starting quarter.
- If the final date is after the latest CPI release, the calculation stops at the latest quarter available.
An example
$1,000 in the June quarter 2015 is worth about $1,370 in the June quarter 2026, an increase of about 37%.

Why does it work by quarter?
The ABS publishes this CPI series once per quarter, so every date inside a quarter uses the same index.
