Inflation Calculator Australia
What is your dollar actually worth? Measure the real value of Australian money across any two years since 1990, compare nominal vs inflation-adjusted salary growth, and see how bracket creep silently erodes pay rises under the current resident tax schedule.

Frequently asked questions
What CPI data does this calculator use?
Annual figures derived from the Australian Bureau of Statistics 6401.0 Consumer Price Index (weighted average of the eight capital cities, All Groups). We rebase the series to 1990 = 100 for readability — relative changes between any two years match ABS published values.
Is the latest year always up to date?
We update the series each time new ABS quarterly data is released. If you need the absolute latest figure, cross-check the ABS website (abs.gov.au) — the cumulative and annualised rates may drift by a fraction of a percent until the next update.
Why did my 'real raise' come out negative?
If your nominal pay rise is smaller than cumulative CPI between the two years, your purchasing power has actually fallen. A 3% raise in a year of 4% inflation is a ~1% real pay cut.
What is bracket creep?
Australia's resident income-tax brackets are not automatically indexed to inflation. When your pay rises only with CPI, a larger share of your income gets pushed into higher brackets even though your real purchasing power hasn't changed — so your after-tax income quietly shrinks in real terms.
Which tax brackets does the bracket-creep tab use?
The 2025–26 Australian resident brackets: 0% to $18,200 · 16% to $45,000 · 30% to $135,000 · 37% to $190,000 · 45% above. The calculator applies these same brackets across every projected year (i.e. assumes they stay frozen).
Does this include the Medicare levy?
No — to keep the bracket-creep illustration clean we only apply the income-tax schedule. Including the 2% Medicare levy would increase the gap slightly but the shape of the loss curve is the same.
How do I interpret 'equivalent value'?
$10,000 in 2000 is worth around $19,000 in 2024 — meaning you would need ~$19,000 today to buy the same basket of goods that $10,000 bought in 2000. The calculator inflates or deflates any amount between any two years in the series.
Is this calculator tax or financial advice?
No. It is an educational tool using published ABS CPI and current ATO tax schedules. Your actual situation may include Medicare levy, HELP, offsets, deductions, and super — speak to a registered tax professional before making decisions.
Tax Accuracy & Sources
CPI values are drawn from ABS 6401.0 (weighted 8 capital cities, All Groups) and rebased to 1990 = 100. Bracket-creep projections use 2025–26 AU resident brackets and exclude Medicare levy, HELP, and offsets.
