Rent Price Index (CPI) — methodology

What this metric measures

ABS Consumer Price Index for rents — the cost of renting a dwelling. Published as an index number (the ABS CPI reference period = 100), not a dollar figure per week.

Why it matters: Rent levels are a key component of cost of living for the approximately 30% of Australians who rent. Rising rents reduce disposable income and can force housing trade-offs.

How the score is computed

The score is a 0–100 normalisation of the latest observation, compared to a baseline window. The traffic-light rating (RAG) reflects both the absolute level and the recent trend.
