How long your retirement savings last in Australia depends primarily on three variables: your starting balance, your annual spending rate, and whether you keep the balance invested through an account-based pension rather than holding it as cash. At a 3.5% sustainable annual drawdown appropriate for a 30-year Australian retirement a $700,000 balance generates $24,500 per year from the portfolio alone, supplemented by the Age Pension as assets reduce below the means test thresholds. The ASFA comfortable retirement standard (February 2026) is $54,840/year for a single homeowner and $77,375/year for a couple meaning most retirees need both super drawdowns and eventual Age Pension support, not one or the other.
This guide walks through exactly how to calculate your personal retirement savings timeline, the factors that make the biggest difference to longevity, and the strategies that extend your savings materially.
How to Calculate How Long Your Retirement Savings Will Last: Step by Step
Step 1: Establish Your Total Retirement Assets
List every financial asset you can draw on in retirement:
- Superannuation balance (all funds)
- Non-super investment accounts (shares, ETFs, managed funds)
- Term deposits, savings accounts, and cash holdings
- Investment property net equity (if you’re planning to sell or can draw rental income)
Do not include your principal home unless you’re planning to downsize it’s your residence, not an income-producing asset (though selling it triggers downsizer contribution opportunities and affects the Age Pension assets test).
Step 2: Establish Your Annual Spending Target
This is the most important number in the calculation. Use the ASFA Retirement Standard as a benchmark, but build your own line-by-line estimate. ASFA’s February 2026 benchmarks for homeowners:
| Lifestyle | Single (Homeowner) | Couple (Homeowners) |
|---|---|---|
| Comfortable | $54,840/year | $77,375/year |
| Modest | $32,915/year | $47,387/year |
If you’re a renter, add $15,000–$20,000 per year. If you’re planning significant early-retirement travel, add $10,000–$20,000 in the first decade. If you have chronic health conditions, add a healthcare buffer. Don’t use a benchmark as your budget use it as a sanity check against your own estimate.
Step 3: Determine Your Withdrawal Rate
The withdrawal rate is the annual amount you’ll draw from your portfolio, expressed as a percentage of the starting balance. This is the single most important variable in longevity calculations more important than the starting balance itself.
| Withdrawal Rate | What It Means | Approximate Portfolio Longevity (balanced portfolio, 6% gross return) | Australian Context |
|---|---|---|---|
| 3% | Very conservative; portfolio likely grows over time | Indefinite likely outlasts the retiree | Appropriate for large balances ($1.5M+) or where Age Pension is not available |
| 3.5% | Conservative; recommended for 30-year horizons | 35–40+ years | Standard recommendation for Australian retirees aged 60–67 |
| 4% | Moderate; US-origin “safe withdrawal rate” | 25–30 years | Acceptable for 67+ retirees with Age Pension supplement from mid-retirement |
| 5% | Aggressive; meaningful depletion risk | 18–22 years | Generally only appropriate if Age Pension is expected to cover most income by 80s |
| 6%+ | Very aggressive; high depletion risk | 14–16 years | Only sustainable with a clear transition to full Age Pension support in the 70s |
A note on the 4% rule: this guideline was derived from US stock and bond market data covering 1926–1994 and was designed for 30-year retirements. For Australians planning 35+ year retirements with different market characteristics, 3.5% is more appropriate as a sustainable starting rate. The ASIC Moneysmart retirement planner allows you to model your specific situation with Australian market assumptions.
Step 4: Factor in Investment Returns
Whether your savings are in cash or invested makes an enormous difference to longevity. Cash earns 4–5% in 2026 market conditions but historically lags inflation over long periods. A balanced 60/40 investment portfolio (60% growth assets, 40% defensive) has historically returned 6.5–7.5% gross per year over 10-year periods before fees and tax and in super’s pension phase, that return is tax-free.
| Starting Balance | Annual Spending | Returns: 0% (Cash) | Returns: 4% (Conservative Portfolio) | Returns: 6% (Balanced Portfolio) |
|---|---|---|---|---|
| $500,000 | $40,000/year | 12.5 years | 17 years | 23 years |
| $700,000 | $50,000/year | 14 years | 20 years | 30+ years |
| $700,000 | $40,000/year | 17.5 years | 26 years | 35+ years |
| $1,000,000 | $54,840/year (ASFA comfortable, single) | 18 years | 28 years | 38+ years |
| $1,000,000 | $77,375/year (ASFA comfortable, couple) | 13 years | 18 years | 25 years |
Estimates are illustrative. They assume constant real returns and spending (no inflation adjustment shown separately). In practice, Age Pension support from mid-to-late retirement extends all of these timelines significantly. These projections do not include the Age Pension see Step 5.
The difference between 0% (all cash) and 6% (balanced portfolio) on a $700,000 balance with $50,000/year spending is the difference between running out at age 81 and running out at around age 97 a 16-year difference from a single investment decision. This is why keeping your retirement savings invested through an account-based pension is one of the highest-impact decisions in retirement planning.
Step 5: Add the Age Pension as a Dynamic Floor
Most longevity calculations stop at the portfolio level. The critical additional step for Australian retirees is modelling when and how the Age Pension supplements the portfolio drawdown.
As of March 2026:
- Full single pension: $1,178.70/fortnight (~$30,647/year)
- Full couple pension: $1,777.00/fortnight combined (~$46,202/year)
As you draw down your super, your assessable assets reduce and at some point, you begin qualifying for a part pension, then eventually the full pension. This progressive pension entitlement effectively provides an income floor that prevents total asset depletion for homeowning Australians who reach 67.
The practical impact: a $700,000 retiree who would otherwise exhaust their savings in 23 years at 6% returns and $50,000/year spending will instead begin receiving a part pension around year 12–15 as their balance falls below the full pension threshold (~$674,000 for single homeowners). The pension supplement reduces their super drawdown requirement, extending the portfolio life materially beyond the uninflected 23-year estimate.
The Factor Most Retirement Calculators Miss: Sequence of Returns Risk
Standard longevity calculations assume a constant annual return say, 6% every year. In reality, investment returns are highly variable, and the order in which returns occur has an enormous effect on how long savings last. This is called sequence of returns risk, and it’s one of the most important concepts in retirement planning.
Here’s the core insight: a significant market downturn in the first 3–5 years of retirement, when you’re simultaneously drawing income, causes permanent damage to your portfolio that a later recovery cannot fully repair. Because you’re selling units at low prices to fund living expenses, you permanently reduce the base from which future returns compound. The same total return over 20 years produces very different outcomes depending on whether the bad years come first or last.
Example: Two retirees, both with $700,000, both drawing $50,000/year, both averaging 6% returns over 20 years:
- Retiree A experiences strong returns in years 1–5, then a crash in years 10–15: portfolio may last 30+ years
- Retiree B experiences a 30% crash in years 1–2, then strong recovery: portfolio may deplete by year 22
Same average return. Same starting balance. Same spending. The order of returns determines the outcome.
The primary protection against sequence of returns risk is a cash buffer of 12–24 months’ living expenses held separately from your growth portfolio. When markets fall, you draw from cash rather than selling growth assets at the bottom. When markets recover, you replenish the buffer. This strategy a core part of the bucket approach is specifically designed to prevent sequence risk from permanently impairing your retirement income.
How Long Will Common Retirement Balances Last? Quick Reference
The following table combines all factors: balanced portfolio returns (6% gross, tax-free in pension phase), 3.5% withdrawal rate as a sustainable baseline, and the approximate point at which Age Pension support begins:
| Starting Balance | Annual Spending (ASFA Comfortable, Single) | Withdrawal Rate | Approx. When Part Pension Begins | Estimated Portfolio Longevity* |
|---|---|---|---|---|
| $300,000 | $54,840 | 18.3% | Immediately (already below threshold) | ~6–8 years as primary income; full pension takes over |
| $500,000 | $54,840 | 11% | ~5–7 years (assets fall below ~$674k) | ~10–13 years primary; part pension growing from year 5 |
| $700,000 | $54,840 | 7.8% | ~10–12 years | ~18–22 years primary; pension from year 10 |
| $1,000,000 | $54,840 | 5.5% | ~18–22 years | ~28–35 years; modest part pension in late retirement |
| $1,400,000 | $54,840 | 3.9% | 25–30 years or not at all | 35–40+ years; largely self-funded throughout |
* Assumes 6% gross annual return in tax-free pension phase (account-based pension); 3.5% net withdrawal after notional returns offset. Single homeowner. Age Pension assessed from age 67. Figures are illustrative individual outcomes depend significantly on actual investment performance, especially in early retirement years. Couple scenarios require approximately 40% higher balances for the same longevity outcome.
In our experience advising 500+ Australian families, the most consistent finding is that people significantly underestimate how long their savings will last when properly managed and overestimate it when poorly managed. The difference is almost always investment strategy (staying invested vs going to cash) and withdrawal discipline (drawing at a planned rate vs ad hoc large withdrawals in early retirement).
The Five Biggest Mistakes That Shorten Retirement Savings
- Moving to cash at retirement the most common and most damaging mistake. Moving the entire super balance to cash at retirement eliminates the investment returns that are essential to longevity. At $50,000/year spending on $700,000 in cash at 4% interest, the money lasts about 20 years. In a balanced portfolio at 6%, it lasts 30+ years
- Large lump sum withdrawals in the first 5 years renovations, luxury purchases, or large gifts in the first 5 years permanently reduce the base from which future returns compound. A $100,000 lump sum at year 3 doesn’t just cost $100,000; it costs the lost compounding on $100,000 for the next 25 years potentially $250,000–$400,000 in foregone portfolio value
- Ignoring the Age Pension transition treating the Age Pension as a distant contingency rather than planning the transition deliberately. Retirees who model when they’ll qualify for part pension can optimize their drawdown rate and lifestyle accordingly, rather than discovering the transition reactively
- Not adjusting withdrawals in bad years drawing the same amount in a year when markets are down 20% as in a year when they’re up 10% destroys significantly more portfolio value. A flexible withdrawal strategy drawing 10–20% less in significant down years materially improves long-term longevity
- Underestimating healthcare costs in the 70s and 80s the AIHW data shows per-capita health spending roughly doubles between ages 65–74 and 85+. A retirement budget that assumes flat spending overestimates longevity in the later years when healthcare costs spike. Build a healthcare buffer or plan for an explicit increase in spending from your mid-70s

Frequently Asked Questions
For a single homeowner drawing $40,000/year from a balanced portfolio earning 6% gross (tax-free in pension phase), $500,000 lasts approximately 21–23 years. At $50,000/year, it lasts around 14–17 years before Age Pension support begins to supplement income. The critical variable is investment returns the same $500,000 held in cash at 4% lasting the same $40,000/year drawdown runs out in about 16 years rather than 23. Age Pension support begins once assets fall below the full pension threshold (~$314,000 for single homeowners), which at a $40,000/year drawdown from $500,000 would occur around retirement year 10–12.
For a single homeowner spending at the ASFA comfortable standard ($54,840/year, February 2026) from a balanced portfolio at 6% gross return, $700,000 lasts approximately 18–22 years without Age Pension support. Once the balance falls below the full pension assets test threshold (~$674,000 for single homeowners), a part pension begins supplementing income extending the effective total income timeline well into the late 80s. For a couple spending $77,375/year from a combined $700,000 balance, the timeline is shorter (approximately 10–14 years) because the higher spending rate draws the balance down faster.
For a single homeowner targeting the ASFA comfortable standard ($54,840/year), $1 million in a balanced portfolio at 6% gross return (tax-free in pension phase) lasts approximately 28–35 years. A couple targeting $77,375/year from a combined $1 million balance will see approximately 18–24 years of full self-funding before Age Pension support begins. The detailed analysis across different scenarios is covered in our guide on whether $1 million is enough to retire in Australia.
For a 30-year retirement starting at age 60–67, 3.5% is the generally recommended sustainable withdrawal rate for Australian retirees more conservative than the US-derived 4% rule, which was designed for 30-year retirements using American market data from 1926–1994. At 3.5%, a $700,000 portfolio withdraws $24,500/year from the portfolio alone; the Age Pension supplements this as the balance reduces over time. For those retiring later (67+) with full Age Pension access from the outset, a 4–4.5% rate may be appropriate. The ASIC Moneysmart retirement planner allows you to model different withdrawal rates against your specific balance.
Sequence of returns risk is the risk that a significant market downturn in the early years of retirement, when you’re simultaneously drawing income, permanently impairs your portfolio more than the same downturn later would. If markets fall 30% in year two of your retirement and you’re drawing $50,000/year, you’re forced to sell more units at low prices, permanently reducing the base from which future returns compound. The primary protection is a cash buffer of 12–24 months’ living expenses held outside your growth portfolio so you draw from cash during downturns rather than selling investments at the bottom. For a full explanation with worked examples, see our guide on whether to keep investing after retirement.
The most impactful strategies are: (1) Keep the majority of your balance invested in a balanced portfolio through an account-based pension the investment return is the most powerful longevity lever; (2) Draw at a sustainable rate of 3.5% and avoid large lump sum withdrawals in the first 5 years; (3) Hold 12–24 months of living expenses in cash to protect against sequence of returns risk; (4) Plan deliberately for the Age Pension transition rather than treating it as a fallback; (5) Adjust withdrawals in poor market years reducing by even 10–15% in a significant down year can materially extend longevity. For the full strategy framework, see our guide on whether you can live off super alone after retirement.
Both, in that order. Free calculators like the ASIC Moneysmart retirement planner give you a reasonable first estimate and help you understand which variables matter most for your situation. But they can’t account for: your full asset picture across super and non-super, the optimal drawdown sequencing for your tax and pension position, the interaction between your super structure and your estate planning, or the specific investment strategy appropriate for your risk profile and income needs. A financial adviser models all of these simultaneously and identifies optimisations — in fees, tax, withdrawal rate, pension timing that typically add far more value than they cost.
Model Your Retirement Timeline With Confidence
Estimating how long your retirement savings will last is not a one-time calculation it’s an ongoing assessment that gets more precise as you get closer to retirement and more specific to your actual circumstances once you’re in it. The five variables that matter most are: starting balance, annual spending, investment returns, withdrawal rate discipline, and Age Pension timing. Get these right and your money will last; get them wrong and even a large balance can deplete surprisingly quickly.
