Purchasing power = 100 × (CPI in September 2025 ÷ CPI this quarter) = 10,000 ÷ CPI, because the CPI is referenced to September 2025 = 100. The inputs are the official series listed under Sources; the result is not published by the source in this form.

About this indicator
- What it measures
- The purchasing power of the Australian dollar with September 2025 = 100. A value of 200 means a dollar then bought twice what it buys at September 2025 prices.
- How it is calculated
- Calculated by us from the all-groups CPI index in RBA table G1: 10,000 ÷ CPI.
- How to read it
- The line falls whenever prices rise. Each 1% rise in prices lowers it by about 1%.
- Caveats
- Uses capital-city consumer prices and says nothing about whether incomes kept pace.
- Frequency
- Quarterly
- Typical release
- Quarterly with the CPI.
