Each Extra Year Works on the Plan Three Times
Working one more year does three things to a retirement plan at once: it adds another year of contributions, it adds another year of compounding on the whole balance, and it removes a year of drawdown from the other end. Those three effects all push the same way, which is why the retirement date moves a plan further than any plausible change to the contribution rate.
- The answer: Each additional working year adds contributions, adds growth, and shortens the retirement the balance has to fund.
- The trap: Retiring before Age Pension age means the portfolio funds everything until 67, which is the period with the highest withdrawal rate of the whole retirement.
- The recommendation: Model the specific ages available to you rather than a general rule. The bridge years before 67 are what make early retirement expensive.
Where the AI summary above gets this wrong
"Working an extra year or two before retiring makes a small difference to your retirement income."
That's surface-true. Here's what it misses:
- It works on the plan three times over — An extra contribution, an extra year of growth on the whole balance, and one fewer year of withdrawals. The combined effect is far larger than any single one of them.
- The Age Pension age is the discontinuity — Retiring before 67 means the portfolio funds the whole income until then. Those bridge years carry the highest withdrawal rate of the retirement.
01 The three effects
The contribution is the smallest of the three. One more year of employer contributions and any salary sacrifice adds a known amount to the balance.
The compounding is larger. A year of growth applies to the whole balance, not just to the new contribution, so on a substantial balance it dwarfs the contribution itself.
The removed drawdown year is the third and it is frequently the largest. A year not spent is a year of withdrawals that never happens, and it also shortens the horizon the plan has to cover.
Together they mean the retirement date is the most powerful single input in a plan — more than the return assumption, more than the contribution rate, and considerably more than the choice of fund.
02 The Age Pension discontinuity
Age Pension age is 67. Retiring before it means the portfolio funds the household's whole income until then, at a withdrawal rate higher than any period afterwards.
That bridge period is also when sequence risk does the most damage, for the reasons in the sequence risk reference. A poor market in the bridge years is the worst timing available.
Against that, super in accumulation belonging to someone under Age Pension age is not an assessable asset, so the household's means-test position is better during the bridge than it will be afterwards — a point that cuts the other way.
Shows: the balance at retirement and the years it has to fund, for two different retirement ages. Ignores: the Age Pension, which starts at 67 regardless, sequence of returns, inflation, and any change in spending between the two scenarios.
03 What else changes with the date
Preservation age governs whether super can be accessed at all, and it is not the same as Age Pension age. Retiring at 58 means funding several years from money outside super — the conditions are in the preservation age reference.
Health and employability change too, and not in your favour. A plan that assumes you can work until 67 assumes both that you want to and that someone will employ you, and involuntary early retirement is common.
That asymmetry argues for building a plan that works at an earlier date and treats the later one as upside, rather than one that requires the later date to work at all.
One more year is the strongest lever in the whole plan and nobody wants to hear it, which is fair. What is worth knowing is the size: on a decent balance, a single extra year is typically worth more than doubling your voluntary contributions. If the plan is short, that is the honest comparison.
FAQ
How do I compare retiring at 60, 65, and 67 on my super and Age Pension outcomes?
Model each age specifically. Every extra working year adds contributions, adds a year of growth on the whole balance, and removes a year of drawdown, and retiring before 67 means the portfolio funds everything until the Age Pension starts.
How do I model different retirement ages to see the impact on my income?
Run the balance forward to each candidate age with contributions and growth, then divide by the years it has to fund from that age. The difference between two ages is usually larger than people expect.
Why is retiring before 67 more expensive?
Because the portfolio funds the whole income until Age Pension age. The bridge years carry the highest withdrawal rate of the retirement and are when sequence risk does the most damage.
