Age Pension Indexation: Why Your Payment Jumps Every March and September
Your Age Pension rises on 20 March and 20 September each year because the law forces it to keep pace with the cost of living and wages. Centrelink runs three separate indexes — the CPI, the PBLCI and the MTAWE benchmark — and applies whichever produces the larger pension. On 20 March 2026 that mechanism lifted the single maximum rate to $1,200.90 a fortnight, up $22.20.
If you have ever watched your pension nudge up twice a year and wondered who decides the amount — nobody decides it. There is no minister sitting down each March picking a number. The increase is the output of a formula written into the Social Security Act 1991, applied mechanically to data published by the Australian Bureau of Statistics (ABS). Once you understand the three moving parts, you can estimate your own next increase weeks before Services Australia announces it.
This guide walks through all three indexes, works a full example of the 20 March 2026 uplift, explains why the income and assets thresholds move on a different day to the payment rate, and shows you the back-of-the-envelope method I use with clients to forecast the September rise.
The three indexes Centrelink uses
The maximum basic rate of pension is indexed twice a year. The process happens in two stages: first the rate is adjusted by a price measure, then it is checked against a wages benchmark. Three figures are involved.
| Measure | What it tracks | Role in the formula |
|---|---|---|
| CPI | The general Consumer Price Index — the price of a standard basket of household goods and services across all Australian households. | One of the two price measures. The pension is moved by the higher of CPI and PBLCI growth. |
| PBLCI | The Pensioner and Beneficiary Living Cost Index — a cost-of-living index built specifically around the spending patterns of pensioner and benefit-recipient households. | The second price measure. Because pensioners spend more on essentials, PBLCI sometimes rises faster than CPI — so it can win. |
| MTAWE benchmark | Male Total Average Weekly Earnings, published by the ABS. The single pension is benchmarked to 27.7% of MTAWE and the combined couple rate to 41.76% of MTAWE. | The wages safety net. After the price adjustment, the rate is topped up if needed so it never falls below the benchmark. |
The 27.7% single figure is derived from the legislated combined-couple benchmark of 41.76% of MTAWE, with the single rate set at 66.33% of the couple combined rate (0.6633 × 41.76% ≈ 27.7%). This is set out in the Department of Social Services Social Security Guide 5.1.8.50.
Australia uses a "best of" design on purpose. CPI alone can understate pensioner inflation (pensioners spend a bigger share on rent, food, power and health). PBLCI fixes that. But in years of strong wage growth, both price indexes can lag the broader economy — the MTAWE benchmark stops pensioners falling behind working Australians. Layering all three means the pension keeps pace with whichever pressure is strongest at the time.
What "whichever is higher" actually means
This is the part that confuses most people, so let's be precise. The phrase covers two separate "higher of" tests, applied in sequence:
Step 1 — the price step (higher of CPI vs PBLCI)
The combined couple rate is first multiplied by an indexation factor based on the greater of CPI growth and PBLCI growth over the relevant six-month reference period. If PBLCI grew 1.9% and CPI grew 1.6%, the pension is lifted by the PBLCI figure. The price index can never reduce the rate — if both measures fell, the rate simply stays flat.
Step 2 — the benchmark check (against MTAWE)
After the price step, Centrelink checks the new combined couple rate against 41.76% of the latest MTAWE figure. If the price-adjusted rate is below that benchmark, it is topped up to the benchmark. If it is already at or above the benchmark, no further increase applies. So the final increase you receive is effectively the larger of (a) the price-driven uplift and (b) whatever it takes to reach the wages benchmark.
In short: prices set the floor, wages set the catch-up, and you always get the bigger of the two. The single rate is then calculated as 66.33% of the resulting couple combined rate.
Pat, 68, single, on the full Age Pension. Pat wants to understand exactly where the 20 March 2026 increase came from.
Before (20 Sep 2025 – 19 Mar 2026): Pat received the single maximum of $1,178.70 per fortnight (base rate plus the pension supplement and energy supplement).
The indexation run for 20 March 2026:
- Price step: Centrelink took the greater of CPI and PBLCI growth over the six months to the December 2025 quarter and applied it to the combined couple base rate.
- Benchmark check: the price-adjusted couple rate was then compared to 41.76% of the latest MTAWE figure and topped up if it fell short.
- Single rate: the new single base rate is 66.33% of the new couple combined base rate.
After (20 Mar 2026 – 19 Sep 2026), Pat's single maximum became:
| Component | Single fortnightly |
|---|---|
| Maximum base rate | $1,100.30 |
| Pension supplement | $86.50 |
| Energy supplement | $14.10 |
| Total per fortnight | $1,200.90 |
The increase: $1,200.90 − $1,178.70 = $22.20 per fortnight, or about $577 extra per year ($22.20 × 26 fortnights). On an annualised basis Pat now receives roughly $31,223 per year. For couples, the combined rate rose by $33.40 a fortnight, each member receiving $905.20 a fortnight.
Figures verified against SuperGuide's published 20 Mar 2026 rate table and the Services Australia "How much Age Pension you can get" page. The $22.20 single / $33.40 couple increase is confirmed by SUPERCentral.
The current rates after the 20 March 2026 indexation
Here is the full breakdown applying from 20 March 2026 to 19 September 2026. Each total is the sum of the base rate plus the pension supplement plus the energy supplement.
| Component (per fortnight) | Single | Couple (each) |
|---|---|---|
| Maximum base rate | $1,100.30 | $829.40 |
| Maximum pension supplement | $86.50 | $65.20 |
| Energy supplement | $14.10 | $10.60 |
| Total maximum per fortnight | $1,200.90 | $905.20 |
| Approximate annual | ~$31,223 | ~$23,535 each |

Why thresholds index on a different cycle (1 July)
Here is a trap that catches even experienced retirees: your payment rate and your income and assets test thresholds do not move on the same day.
- Payment rates (the maximum pension, supplements) index on 20 March and 20 September using CPI / PBLCI / MTAWE, as described above.
- Test thresholds — the income test "free area", the deeming thresholds, and the assets test limits — index on 1 July each year, with reference to CPI only.
That is why you might see your fortnightly payment rise in March, then see the amount of income you can earn before your pension reduces rise separately in July. They are governed by different provisions in the legislation and tied to different reference periods. The income test reduces your pension by 50 cents for every dollar of fortnightly income above the free area, so a July lift in the free area can be worth more than the March rate rise for part-pensioners.
If you are a part-pensioner near a threshold, watch two dates, not one. A March rate rise increases your maximum entitlement, but a July threshold rise can increase your actual payment by reducing how much of your income or assets counts against you. Note too that the deeming rates (the percentages applied to your financial assets) are a separate lever the government can change at any indexation point — distinct from the 1 July threshold indexation. Confirm both on the income test and deeming pages.
How to estimate the next September increase before it's announced
You do not have to wait for Services Australia. The price step relies on ABS data that is published well before each indexation day, so you can build a reasonable estimate yourself. Here's the method I use.
Step 1 — find the reference quarters
The 20 September indexation is driven by growth over the six months to the June quarter (versus the prior December quarter). The 20 March indexation uses the six months to the December quarter. The ABS releases the relevant CPI and PBLCI figures in late July (for the June quarter), giving you weeks of lead time.
Step 2 — take the higher of CPI and PBLCI
Pull both index numbers from the ABS price indexes for the two reference quarters. Calculate the percentage growth for each, then keep the larger one. That is your provisional price-step factor.
Step 3 — apply it and sanity-check against MTAWE
Multiply the current combined couple base rate by your price-step factor to get a draft new rate, then convert to the single rate (66.33%). If wage growth has been strong, check the result is not below 41.76% of the latest MTAWE figure — if it is, the real increase will be larger.
Suppose, ahead of September 2026, the June-quarter ABS data shows PBLCI grew 1.4% over six months and CPI grew 1.1%. You take the higher figure, 1.4%.
Apply it to the current single total of $1,200.90: $1,200.90 × 1.014 ≈ $1,217.70, an estimated rise of about $16.80 a fortnight. (In practice the factor is applied to the base rate and supplements separately, and rounded to the nearest 10 cents, so treat this as a ballpark.) If MTAWE had surged, the actual figure could come in higher after the benchmark check. This is exactly how seniors' organisations such as National Seniors Australia's indexation estimator produce their pre-announcement forecasts.
- Two indexation days: payment rates rise on 20 March and 20 September every year — automatically, by formula, not by ministerial choice.
- Three indexes: CPI and PBLCI are the price measures (higher of the two wins); the MTAWE benchmark (27.7% of MTAWE for singles, 41.76% combined for couples) is the wages safety net.
- "Whichever is higher" means you get the larger of the price-driven uplift and the top-up needed to reach the wages benchmark.
- 20 March 2026: the single maximum rose $22.20 to $1,200.90 a fortnight; couples rose $33.40 to $905.20 each.
- Different cycle for thresholds: income/assets free areas and deeming thresholds index on 1 July (CPI), not in March/September — watch both dates.
- You can forecast September using ABS June-quarter CPI/PBLCI data released in late July, before the official announcement.
Frequently asked questions
Does the Age Pension ever go down at indexation?
No. The price step can only increase the rate or leave it unchanged — if both CPI and PBLCI fell, the rate stays flat rather than dropping. The MTAWE benchmark check can only add to the rate. Your maximum entitlement never reduces at an indexation event.
What's the difference between CPI and PBLCI?
CPI tracks prices across all Australian households. PBLCI (Pensioner and Beneficiary Living Cost Index) is built around the spending patterns of pensioner and benefit households specifically — who spend proportionally more on essentials like food, rent and power. When those costs rise faster than the general basket, PBLCI can grow faster than CPI, and the pension is moved by the higher of the two.
What is the MTAWE benchmark and why 27.7%?
MTAWE is Male Total Average Weekly Earnings, published by the ABS. The combined couple maximum base rate is legislated to sit at 41.76% of MTAWE; the single rate is 66.33% of the couple combined rate, which works out to about 27.7% of MTAWE. It acts as a floor so pensioners keep pace with wage growth, not just prices. See the DSS Social Security Guide 5.1.8.50.
Why didn't my income test free area change in March?
Because the income test free area, the deeming thresholds and the assets test limits index on 1 July each year (using CPI), not on the March/September payment-rate cycle. They are governed by separate provisions. So your maximum payment can rise in March while your thresholds wait until July.
How much was the 20 March 2026 increase?
The single maximum rate rose by $22.20 a fortnight, from $1,178.70 to $1,200.90 (about $577 more a year). The combined couple rate rose by $33.40 a fortnight, to $905.20 each. Figures confirmed against Services Australia and SuperGuide.
Can I estimate the next increase myself?
Yes. For the September rise, take the higher of CPI and PBLCI growth over the six months to the June quarter (ABS publishes this in late July), apply it to the current rate, then sanity-check against the MTAWE benchmark. It will be close, though final rounding and the benchmark top-up can shift it slightly.
