An employee in their late 30s wants to know if they are on track for a comfortable retirement. They have $85,000 in super already and want to see what they will have at 67 before deciding whether to make voluntary contributions.

1 What this calculator does
Projects superannuation balance at retirement from current balance, salary, age and investment return. Compounds employer SGC contributions (11.5% in 2024-25) plus any voluntary additional contributions annually at the chosen return rate. Shows total contributed, growth component and final balance.
2 Formula & professional reasoning
Annual SGC contribution = Salary x 11.5%
Annual total contribution = SGC + Extra voluntary contributions
Balance each year = (Balance + Annual contributions) x (1 + Return rate)
Final balance = Compound growth over (Retirement age - Current age) years
The compound growth calculation applies the investment return to both the existing balance and new contributions each year. The employer SGC rate is 11.5% in 2024-25 and rises to 12% from 1 July 2025. The long-run average return for a balanced super fund is approximately 7% after fees -- a reasonable default for projections. The final balance is compared to ASFA's comfortable retirement standard ($690,000 for couples, $595,000 for singles as at 2024).

5 Common errors
| Error | Cause | Consequence | Fix |
|---|---|---|---|
| Forgetting that the return shown is before fees and inflation | Treating the gross return as the real return | Projected balance overstated -- purchasing power of the balance is lower after inflation | For inflation-adjusted projections, subtract 2-3% from the nominal return (e.g. use 4-5% instead of 7%). This gives the real (purchasing power) value of the final balance. |
| Not checking that your employer is paying the correct SGC rate | Assuming the payslip is correct | Missing super contributions -- compounding effect of underpayment is severe over 20-30 years | Check your super fund statement against your payslip. SGC must be 11.5% of ordinary time earnings in 2024-25. If not being paid correctly, contact the ATO's unpaid super hotline. |
| Using the same return rate for the growth phase and retirement phase | Single-rate planning | Unrealistic retirement income projections -- different funds and products in retirement | The accumulation phase (building super) uses your working years return. In retirement, many people shift to a more conservative allocation with lower expected returns. Use separate projections for each phase. |
| Not considering the super tax concession on voluntary contributions | Comparing extra super contributions to take-home saving at the same gross amount | Under-valuing salary sacrifice -- it is more efficient than post-tax saving | Before-tax salary sacrifice contributions are taxed at 15% in super instead of your marginal rate. At 32.5% marginal rate, every $1,000 sacrificed costs only $850 after the 17.5% saving vs $672.50 from take-home pay. |
