An Australia Superannuation and retirement calculator that projects how large your Super balance could grow and the annual retirement income it can sustainably provide. It is built around Australia’s mandatory system: the Super Guarantee (SG), currently 11.5% of salary, paid by your employer, plus any voluntary contributions you add.
How it works
The tool runs a year-by-year simulation from your current age to retirement. Each year:
contribution = salary * (SG% + voluntary%)
balance = (balance + contribution) * (1 + return%)
salary = salary * (1 + salaryGrowth%)
Contributions land in the fund and the whole balance compounds at your expected after-fee return. Because salary grows over time, contributions rise too, and decades of compounding do most of the heavy lifting.
To estimate retirement income, the projected balance keeps earning a return in retirement and is drawn down as a sustainable annuity over the years between your retirement age and your planned end age:
annualIncome = balance * r / (1 - (1 + r)^-yearsInRetirement)
where r is the in-retirement return. This is the level annual amount that exhausts the balance over that period.
Example and notes
A 30-year-old earning 90,000 AUD with a 50,000 AUD Super balance, an 11.5% SG, a 6% after-fee return and retirement at 67 could project a balance well into the high six figures, supporting a meaningful annual income through to age 90.
