The five questions that matter more than any retirement number
Last week we looked at the retirement gap — the distance between what most Australians have saved and what a comfortable retirement actually requires.
This week I want to talk about the tool most people reach for when they start thinking about that gap: the retirement calculator.
Retirement calculators are useful. They give you a starting point, a rough projection, a way to visualise the numbers. Used well, they can prompt important conversations and decisions.
But there is something a calculator cannot do.
It cannot account for the fact that your life will change.
A retirement calculator takes the information you give it today — your current balance, your contribution rate, an assumed investment return — and projects it forward to a single number at a single point in time.
That number feels authoritative. It feels like an answer.
But it is built on assumptions. And assumptions have a way of not surviving contact with reality.
Investment returns vary. Inflation behaves unpredictably. Careers take unexpected turns. Health changes. Family circumstances shift. The retirement you picture at 45 will look quite different from the one you actually want at 60.
A number calculated once and never revisited is not a plan. It is a snapshot of a single moment in time.
Rather than anchoring to a single figure, the most useful retirement planning begins with questions.
What does my ideal retirement actually look like? Not a vague sense of "comfortable" — but specifically. Where will you live? What will a typical week feel like? How much will you travel? How will you spend your time?
When would I like to retire, and is that realistic? Retiring at 60 versus 67 is not simply a matter of preference. It changes the amount you need to save, the length of time your savings must last, and your Age Pension eligibility.
How long might my savings need to last? A woman retiring at 65 in Australia has a life expectancy of approximately 87 years. Planning for 20 years of retirement may leave you significantly short.
What happens if returns are lower than expected? Most calculators use optimistic long-term averages. What does your position look like if returns are 1–2% lower than projected for a decade?
What is my buffer for the unexpected? Healthcare costs, aged care, supporting adult children, major home repairs — these are not unusual. They are simply the texture of a real life lived over decades.
Use a retirement calculator not to find an answer, but to test your assumptions.
Run it at the expected return. Then run it 2% lower. See what changes. Run it assuming you retire at 65. Then at 60. Then at 67.
The number is less important than your understanding of how sensitive your plan is to the variables that life will inevitably change.
The people who retire well are rarely the ones who found the right number. They are the ones who built a flexible plan and returned to it regularly.
