How much super will you have at retirement?
What drives your final balance — contributions, time and returns — and the levers that move it most.
Last updated 3 November 2026
Your super balance at retirement isn’t really about luck — it comes down to four levers you can mostly see and, for some of them, pull. Understanding what moves the number most is how you make decades of small decisions add up.
The four things that decide your final balance
- Contributions in. The 12% employer super guarantee is the base. Extra contributions — salary sacrifice or after-tax — add directly on top.
- Time. Super compounds over your whole working life, so years in the market matter more than almost anything else.
- Investment return. Your fund’s option (growth, balanced, conservative) sets the long-run return, after fees. Small differences compound into large gaps over 30+ years.
- Fees and insurance. Admin fees, investment fees and insurance premiums are a drag that also compounds — a percentage point of fees can cost tens of thousands over a career.
Why time dominates
Because super compounds, when money goes in matters as much as how much. A dollar added in your 30s has three decades to grow; the same dollar added in your late 50s has only a few years. That’s why the single most powerful move is usually just letting it run — and adding a little early rather than a lot late.
An illustration
Take someone on $90,000 with the 12% guarantee — about $10,800 a year going in. Over a long career, with typical long-run returns and the balance reinvested, the compounding on those contributions ends up dwarfing the contributions themselves: most of a final balance is growth, not the amounts paid in. The exact figure depends heavily on return and fee assumptions, which is why it’s worth projecting with your own numbers rather than relying on a rule of thumb.
Accessing it
You can generally access super once you reach preservation age and retire — for everyone born from 1 July 1964, that’s age 60. From 1 July 2026, Payday Super means your employer pays super alongside each payday, so it starts compounding a little sooner than the old quarterly system.
Project your own balance
Our superannuation calculator projects your balance from your salary, contributions and assumptions, and the compound interest calculator shows how extra contributions grow over time.

Frequently asked questions
What determines how much super I'll have at retirement?
Four things: how much goes in (the 12% employer guarantee plus any extra contributions), how long it compounds, the investment return after fees, and the fees and insurance premiums charged. Time and returns do most of the heavy lifting because super compounds over decades.
How much super does the employer have to pay?
Employers must pay the super guarantee — 12% of your ordinary earnings from 1 July 2025. From 1 July 2026, Payday Super requires that super to be paid at the same time as your wages rather than quarterly, which means it starts compounding sooner.
When can I access my super?
Generally once you reach your preservation age and retire. For everyone born from 1 July 1964 onwards, preservation age is 60. You can usually access it fully from 65 even if still working. There are limited early-access exceptions.
Do small extra contributions really make a difference?
Yes — a lot, because of compounding. An extra contribution in your 30s has decades to grow, so it can add far more to your final balance than the same contribution made close to retirement. Concessional (before-tax) contributions can also reduce your income tax.
