Rates & sources
Compound growth assumes reinvested returns and no platform fees. Past performance is not a guide to future returns.

When to use this calculator
- Before choosing between saving, investing, or increasing your monthly contribution.
- When you want to compare best-case, base-case, and cautious return assumptions.
- When you need a quick projection before making a longer-term portfolio decision.
- When you are deciding how many more years of contributions are needed to reach a specific target balance.
- When you want to see whether starting earlier versus contributing more each month produces a bigger outcome.
A realistic Australia planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Your Current Age
35
Retirement Age
35
Current Super Balance (A$)
A$1,400
Annual Salary (A$)
A$80,000
After entering these figures, review projected super balance, your contributions and investment growth together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
Projected Super Balance
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Your Contributions
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Investment Growth
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Estimated Annual Drawdown (4%)
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Annual SGC
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Method & assumptionsAuthoritative sources
This calculator projects your superannuation balance at retirement using Australia’s 2024/25 rules. Employer contributions are calculated at the Superannuation Guarantee Contribution rate (defaulting to 11.5%), combined with any voluntary salary sacrifice, and capped at the concessional contributions limit of $30,000. A flat 15% contributions tax is deducted before crediting the net amount to your balance each year, replicating how complying super funds handle concessional contributions. Your existing balance and annual net contributions are then compounded at the expected growth rate for the remaining years to retirement.
Important caveats: this model uses end-of-year compounding and does not account for fund fees, insurance premiums inside super, the Division 293 tax on high earners, or the impact of investment market volatility. It also excludes the Age Pension, which remains a meaningful income supplement for many retirees. The 4% annual drawdown figure is illustrative only. For personalised advice, consult a licensed financial adviser or use the MoneySmart Retirement Planner provided by ASIC.
Common mistakes
- !Assuming a constant return without checking a more conservative growth rate.
- !Forgetting to include ongoing contributions, fees, or tax wrappers where relevant.
- !Focusing only on the final balance instead of the path required to reach it.
- !Ignoring the drag of platform fees or fund charges, which can reduce the real compounded return significantly over ten or more years.
- !Comparing ISA and general investment account projections without adjusting for the tax treatment of interest, dividends, or capital gains.
What to do next
- Test a cautious, expected, and optimistic growth rate instead of relying on a single projection.
- Compare this result with related savings or retirement tools before committing more money.
- Use the linked guides to understand which assumptions matter most over longer periods.
- Consider running the same figures in an ISA and a general account scenario to see how the tax treatment changes the outcome over ten or more years.
- If the projected balance falls short of your target, use the tool to work backwards — increase the monthly contribution until the result meets your goal.
