Twice a Year, Against Three Measures, Whichever Is Higher
The Age Pension is indexed on 20 March and 20 September each year to the higher of the Consumer Price Index and the Pensioner and Beneficiary Living Cost Index, and is then benchmarked against a percentage of male total average weekly earnings. That combination means it has broadly tracked wages rather than prices, which is a materially better outcome over decades.
- The answer: Indexed twice a year to the higher of the CPI and the pensioner living cost index, then increased if needed to meet the earnings benchmark.
- The trap: The thresholds and the payment are indexed on different schedules — assets thresholds also move in July — so a part pension can change three times a year.
- The recommendation: Model the pension as growing with wages rather than with prices over a long retirement. The difference across thirty years is substantial.
Where the AI summary above gets this wrong
"The Age Pension increases each year with inflation."
That's surface-true. Here's what it misses:
- It is indexed twice a year, not once — On 20 March and 20 September, to the higher of the CPI and a living cost index specific to pensioner households.
- The earnings benchmark is what actually drives it — After the price indexation, the payment is compared to a percentage of male total average weekly earnings and increased if it falls short — so over time it tracks wages.
01 The indexation mechanism
Twice a year the maximum basic rate is increased by the greater of the movement in the Consumer Price Index and the movement in the Pensioner and Beneficiary Living Cost Index, which measures a basket weighted to pensioner spending.
The result is then compared against a benchmark set as a percentage of male total average weekly earnings. If the indexed rate falls below the benchmark, it is increased to meet it.
That third step is why the pension has broadly kept pace with wages rather than with prices, and it is the single most important feature of the payment for a long retirement.

02 Why the difference compounds
Wages have grown faster than prices over most long periods. A payment indexed to wages therefore rises in real terms, while one indexed to prices only holds its purchasing power.
Over a thirty-year retirement that difference is large. The worked example compares the two paths on a starting rate you supply, and the gap by year thirty is usually a surprise.
It also means a plan that models the Age Pension as a fixed real amount is being conservative, which is the right direction to be wrong in but worth knowing about — the point made in the withdrawal rate post.
Shows: the Age Pension after a period indexed to wage growth against the same payment indexed to price growth. Ignores: the twice-yearly timing, the living cost index, the earnings benchmark's exact percentage, and any policy change.
03 The other things that move
The income and assets thresholds are indexed too, on their own schedule: assets thresholds in July, income free areas in July, and deeming thresholds separately again.
For a part-pensioner that means the payment can change several times a year for reasons unconnected to their own circumstances. The reassessment is automatic and requires nothing from them.
The supplements attached to the payment are indexed alongside it, as is Rent Assistance — the mechanics are in the Rent Assistance reference.
Aged care fees move on the same rhythm, because the basic daily fee is defined as a percentage of the single pension rate. A resident's fee therefore rises every March and September without anything about their circumstances changing, which is why a multi-year care budget has to be indexed rather than held flat.

The earnings benchmark is the part that matters and almost nobody mentions it. A payment linked to wages rather than prices rises in real terms over a long retirement, which makes the Age Pension a materially better floor than a price-indexed one — and most retirement models assume the weaker version.
FAQ
How often is the Age Pension indexed?
Twice a year, on 20 March and 20 September, to the higher of the Consumer Price Index and the Pensioner and Beneficiary Living Cost Index, then benchmarked against a percentage of male total average weekly earnings.
Does the Age Pension keep up with inflation?
It has done better than that. The earnings benchmark means it has broadly tracked wages rather than prices, which over long periods means it has risen in real terms.
Do the thresholds move at the same time?
No. Assets and income thresholds are indexed in July on their own schedule, and deeming thresholds separately again, so a part pension can change several times a year.
