Calculate how inflation has affected the value of money over time using official Australian CPI data.
The Consumer Price Index (CPI) measures the percentage change in the price of a basket of goods and services consumed by households. In Australia, the CPI is calculated by the Australian Bureau of Statistics (ABS) and released quarterly.
The CPI is widely used as a measure of inflation and is an important indicator for economic policy decisions, including those made by the Reserve Bank of Australia (RBA).
This calculator uses official ABS data (Series ID: A2325846C) to calculate how prices have changed over time.
