What is Inflation?
Inflation measures the increase in prices over time, reducing the purchasing power of money. Australia's inflation is measured by the Consumer Price Index (CPI), published quarterly by the ABS.
How this calculator works
This calculator uses official ABS CPI data from 2000 to 2025 to show how the value of money has changed. It applies each year's actual inflation rate sequentially to calculate the cumulative effect. The year-by-year table shows each annual rate and the running value, with high-inflation years (like 2022's 7.8%) highlighted. The purchasing power figure tells you what percentage of buying power a dollar has lost over your chosen period.
Australian CPI History
RBA target band: 2-3% over the cycle. Long-run average (1991-2024) ~2.6%. Major spikes: 2008 GFC year (4.4%), 2022 post-COVID (7.8% peak), 1990 (8.0%). Long flat period 1993-2007 averaged ~2.5%. Inflation cooled from 2022 peak to ~3.5% by mid-2024. RBA cash rate rose from 0.1% to 4.35% (2022-2024) to fight inflation.
What CPI Measures
ABS-tracked basket of 87 product categories representing typical urban household spending. Weighted by household expenditure: housing (~22%), food (~17%), transport (~11%), recreation (~13%), insurance/financial (~5%), etc. Updated quarterly. Headline CPI vs Trimmed Mean (RBA's preferred 'core' measure): trimmed mean strips volatile items (fuel, fresh food) to show underlying trend.
Why Inflation Matters
$100 in 2000 had the purchasing power of ~$50 in 2024 (CPI roughly doubled). $1M today buys what $500k bought in 2000. For retirement planning: a 25-year retirement at 3% inflation halves your purchasing power. Salary increases must beat inflation to be 'real' raises. Investments below inflation rate (high-interest savings at 4.5% vs CPI 3%) earn negative REAL returns after tax.
Inflation-Linked Items in Australia
Centrelink payments indexed to CPI 2x/yr (March/September). Tax thresholds indexed annually (Stage 3 tax cuts). Super contribution caps indexed in $2,500 increments. Transfer Balance Cap indexed in $100k increments. HECS-HELP balance indexed to CPI on 1 June. Property prices/rent often outpace CPI long-term.
