Money by Life Stage — Personal Finance Guides for Every Age

Financial priorities change significantly throughout life. The decisions that matter most in your 20s — building an emergency fund, avoiding costly debt, starting to invest — are different from the priorities of your 40s, when the focus typically shifts to maximising superannuation, accelerating mortgage repayment and planning for retirement.

Each decade brings different income levels, expense patterns, risks and opportunities. The financial mistakes you’re most likely to make in your 20s are different from those you’re most likely to make in your 50s. Understanding the typical milestones and priorities for each life stage helps you identify where to focus your energy.

Your 20s — Build the Foundation

Your 20s are the most important decade financially, even though they rarely feel that way. The reason is time: compound growth is most powerful at the start of its run. Money invested at 25 has 40 years to compound before retirement. The same money invested at 35 has only 30 years.

Key priorities in your 20s

Build a 3-month emergency fund first. Before investing, before paying extra off your HECS debt, before anything else — build a cash buffer. An emergency fund is financial insurance. Without it, any unexpected expense (car repair, medical bill, job loss) becomes a debt problem.

Understand your superannuation. Most Australians in their 20s are in their employer’s default super fund without having chosen one. Log into your super fund, check the investment option you’re in, compare the fees to the market, and consider whether consolidating multiple accounts makes sense. Even a 0.5% reduction in annual fees has a large impact over 40 years.

HECS-HELP: understand the rules before making extra repayments. HECS-HELP debt accrues at CPI (not a commercial interest rate) and repayments happen automatically through the tax system once you earn above the threshold ($54,435 in FY2025–26). Making voluntary extra repayments only makes mathematical sense if the CPI rate exceeds your expected investment return — which is rarely the case over the long term.

Start investing, even small amounts. ASX-listed ETFs allow you to invest from as little as $100 on platforms like CommSec Pocket, Raiz or Spaceship. The habit is more important than the amount at this stage. Starting at 22 instead of 32 can mean hundreds of thousands of dollars more at retirement due to compound growth.

Build a credit history. Lenders assess credit when you apply for a home loan. Using a credit card and paying it off in full each month (never carrying a balance) builds a positive credit history without accruing interest. First home buyers often underestimate how much their credit file matters.

Avoid lifestyle debt. Car loans, personal loans and credit card balances all carry interest rates that make them wealth-destroying. A $25,000 car loan at 9% costs approximately $6,500 in interest over 4 years. Buying within your means from the start — even if that means a more modest lifestyle — has an outsized long-term impact.

Your 30s — Build Wealth Deliberately

The 30s are often the most financially complex decade. Incomes tend to rise, but so do expenses — mortgages, children, and career changes frequently coincide. The challenge is maintaining savings momentum while managing significantly higher fixed expenses.

Key priorities in your 30s

If buying property, understand all the costs. Stamp duty, lenders mortgage insurance (LMI), building and pest inspections, conveyancing, and ongoing maintenance are costs many first home buyers underestimate. The total purchase costs can add 4–6% to the property price. Budget for them.

Review your superannuation — and consider salary sacrifice. By your 30s, salary sacrifice into super is likely to be tax-effective. Contributions made via salary sacrifice are taxed at 15% inside super rather than your marginal tax rate. On an income of $100,000, the marginal tax rate is 34.5% (including Medicare levy) — making salary sacrifice a 19.5 percentage point tax advantage on each dollar contributed.

The concessional contributions cap is $30,000 per year (FY2025–26), including your employer’s 11.5% contributions. The surplus capacity above employer contributions is available for salary sacrifice or personal deductible contributions.

Build an investment portfolio outside super. Super is the most tax-efficient long-term investment vehicle for most Australians, but it’s locked until preservation age (60 for those born after 1964). Building a portfolio of ETFs in your own name gives you access to capital before retirement — useful for property upgrades, school fees, or the option to reduce working hours earlier.

Review insurance. Once you have a mortgage and dependants, the risk of not being insured increases dramatically. Income protection insurance (which replaces your income if you’re unable to work due to illness or injury) becomes particularly important. Review what’s available inside your super fund and whether it’s sufficient or whether additional cover outside super is warranted.

Don’t let lifestyle inflation consume income growth. Pay rises tend to fund lifestyle upgrades — a bigger car, a nicer holiday, a more expensive suburb — rather than savings increases. Deliberately directing a proportion of every pay rise to savings before lifestyle adjusts is one of the most effective wealth-building habits.

Your 40s — Accelerate

The 40s are typically the peak earning years for most Australians, and simultaneously the most powerful wealth-acceleration window. Mortgage repayments become more manageable as the principal falls, children may be approaching or in secondary school (reducing some direct costs), and salaries are typically near their highest.

Key priorities in your 40s

Maximise superannuation contributions. At this stage, salary sacrifice to the full concessional cap ($30,000/year) is often feasible and highly effective. The tax savings compound over the remaining 20+ years to preservation age.

Use catch-up concessional contributions. If your super balance was below $500,000 at the start of the financial year, you can carry forward unused concessional cap space from up to 5 prior years and make a larger one-off contribution. This is particularly useful for people who took career breaks or reduced hours for caring responsibilities.

Review and revise your retirement income projection. At 45, you have approximately 20 years to retirement. A projection of your likely super balance at 60–65, combined with your other assets, tells you whether you’re on track — and if not, how much the gap is and what options are available to close it. ASIC’s MoneySmart retirement planner is a useful starting tool.

Mortgage strategy: offset vs invest. By the mid-40s, many Australians have sufficient equity to consider whether additional money is better directed to the mortgage or to investments. There is no universal answer — it depends on the mortgage interest rate, expected investment returns, tax position, and risk tolerance. Many people split contributions between both.

Consider financial advice. As assets and complexity increase, the value of professional financial planning advice typically increases too. A good financial adviser can optimise tax position, review insurance, structure investments effectively and model retirement scenarios. Fee-for-service advice from an AFSL-licensed adviser is the most transparent model.

Your 50s — Transition and Prepare

The 50s are a transition decade: the final stretch of peak earning, an approaching preservation age, and the need to think concretely about how retirement will actually be funded and structured.

Key priorities in your 50s

Transition to Retirement Income Stream (TRIS). From age 60 (preservation age for those born after 1964), you can access your super via a Transition to Retirement Income Stream while still working. This allows you to draw some income from super — potentially at a lower tax rate — while continuing to receive salary and make contributions. The strategy needs careful modelling.

Non-concessional contributions (after-tax contributions). If you’ve sold an asset (e.g., an investment property) and have a large lump sum, the non-concessional contributions cap of $110,000 per year (or $330,000 using the bring-forward rule) allows significant tax-advantaged retirement asset transfers.

Downsize contribution. Australians aged 55 or over who have owned their home for at least 10 years can make a downsizer contribution of up to $300,000 each ($600,000 per couple) from the proceeds of selling their home into super. This contribution does not count against the non-concessional cap.

Pension income sequencing risk. As retirement approaches, the investment risk inside super should be reviewed. A market crash shortly before or after retirement can have a disproportionate impact when you’re drawing down rather than accumulating. Many super funds offer lifecycle or capital stable options for members approaching retirement.

Frequently Asked Questions

What should I prioritise — super or paying off my mortgage? Both improve net worth, but they do so differently. Extra mortgage repayments reduce guaranteed interest costs (currently 5–7%). Super contributions via salary sacrifice save tax at your marginal rate (which may be 34.5% or higher) and invest at long-run market returns. For most people in their 40s–50s, a combination of both is sensible.

Is it too late to start investing in my 40s? No. A 45-year-old starting to invest today has a 40+ year investment horizon if they live to average life expectancy. Starting later means starting — and starting is always better than not starting.

How do I know if I’m on track for retirement? The ASFA Retirement Standard estimates that a comfortable retirement requires approximately $73,337/year for a couple and $51,630/year for a single. Your super fund and ASIC’s MoneySmart retirement calculator can project your estimated balance at retirement. The gap between the projected balance and what you need tells you how much additional saving is required.
