Is this a historical CPI calculator?

No. It compounds the constant annual rate entered. Historical inflation varies by month and year, so use the ABS CPI index when comparing two actual dates.

Does the RBA target mean inflation will be 2 to 3% every year?

No. The target applies over time. Actual inflation can be above or below the target range, sometimes materially.

What is CPI and how is it measured?

The ABS Consumer Price Index measures changes in the price of a basket of goods and services purchased by metropolitan households. A complete CPI has been published monthly since October 2025, with quarterly tables retained.

Does CPI predict property prices?

No. CPI is a consumer-price measure. Property prices are affected by credit, income, supply, location and other factors and can move differently from CPI.
