What CPI data does this use?
This calculator uses the ABS Consumer Price Index (CPI) All Groups, weighted average of 8 capital cities. Base year is 2013 = 100.0. Data covers 2000 to 2025.
How is the inflation rate calculated?
We calculate cumulative inflation as the percentage change in CPI between your start and end years, and annualized rate as the constant yearly rate that would produce the same cumulative change.
Why does my money lose purchasing power?
Inflation means prices rise over time. If CPI doubles, the same dollar buys half as much. A negative purchasing power change means you need more dollars to buy the same goods.
