This calculator provides general information only and does not take into account your personal objectives, financial situation, or needs. It is not intended to be financial advice.
You should consider whether the information is appropriate for you and seek advice from a licensed financial adviser before making any financial decisions. For independent guidance, visit ASIC MoneySmart.
All results are based on user-defined assumptions and simplified modelling. Actual outcomes may differ materially due to market movements, inflation, taxation changes, and personal circumstances.

This illustrates the model's sensitivity to your chosen assumptions — it is not a prediction. The outcome changes significantly with different return rates, inflation, or withdrawal levels. Consider exploring: retiring later, increasing contributions, or modelling a lower withdrawal rate.
Total portfolio balance (super + savings) projected from current age to planning horizon across three scenarios. Vertical line marks retirement age.
Compares conservative (5.5% return / 3.5% inflation), balanced (7.5% / 2.6%), and aggressive (9.5% / 2.0%) scenarios using your other inputs.

During the accumulation phase (from current age to retirement age), each year's balance is modelled as:
A(t+1) = (A(t) + C) × (1 + r)
Where A is the total balance, C is the annual contribution, and r is the annual return rate. Super and personal savings are tracked separately with their respective return assumptions.
During retirement (from retirement age to planning horizon), each year's balance is modelled as:
D(t+1) = (D(t) − W_net) × (1 + r)
Where W_net is the net withdrawal after any Age Pension supplement, and r is the return rate. Withdrawals are drawn proportionally from super and savings balances. If inflation-adjusted withdrawals are enabled, W grows by CPI each year.
The model applies a simplified asset-test taper for a single homeowner (2024-25 rules):
This is a rough approximation. The actual Age Pension calculation uses both an assets test and an income test, and thresholds vary for couples and non-homeowners. Consult Services Australia for accurate eligibility.
The modelled annual income is derived from a growing annuity present-value formula, which calculates the maximum sustainable withdrawal level such that funds last to the planning horizon, given the blended return rate and inflation assumption.
When "Display in real terms" is enabled, all projected balances and withdrawals are deflated by the cumulative CPI factor to express them in today's purchasing power (real dollars). Nominal figures are raw future amounts without adjustment.
| Scenario | Super return | Savings return | Inflation |
|---|---|---|---|
| Conservative | 5.5% | 4.5% | 3.5% |
| Balanced | 7.5% | 6.0% | 2.6% |
| Aggressive | 9.5% | 8.0% | 2.0% |
Important: All results are illustrative projections based on simplified models and user-defined assumptions. They do not account for taxation on investment returns, super contribution tax, means testing complexity, healthcare costs, aged care, estate planning, or individual circumstances. Results are highly sensitive to the return and inflation assumptions. Actual outcomes may differ materially. This tool does not constitute personal financial advice. Jurisdiction: Australia.
