Retirement Calculator Australia 2026-27

How the retirement calculator works

The core logic rests on a simple principle: if your investment portfolio is large enough, the returns it generates each year can cover your living expenses without depleting the balance. The question is how large "large enough" actually is.

The default 4% withdrawal rate is a starting point derived from historical US portfolio research, not an Australian guarantee. At 4%, the target is 25 times annual spending. The calculator lets you lower or raise the rate so you can see how that assumption changes the target and timeline.

The calculator projects your invested assets forward year by year. It converts the nominal return to a real return after inflation, compounds the existing portfolio, and adds the annual amount you actually invest. Retirement age is the first year the portfolio reaches the selected target. Coast FIRE is the earliest point when that accumulated balance could reach the target by your chosen Coast age without further contributions.

Inputs include current age, invested assets, annual after-tax contributions, retirement spending, nominal return, inflation, withdrawal rate and Coast target age. The calculator does not infer savings from gross income because tax, super, debt repayments and household cash flow differ too much between users.

Retirement targets by annual spending

The table below shows the portfolio target at different spending levels using the default 4% withdrawal rate. If you include super, remember this simple total does not enforce when that super becomes accessible.

These are starting points. Your actual requirement may be lower if you expect Age Pension income after 67, or higher if you want a larger safety margin. Adjust spending in the calculator above to see how each $10,000 change shifts the target and timeline.

What the simple portfolio model leaves out

This calculator deliberately asks for the amount you invest after tax rather than estimating it from salary. Australian tax, super access, Age Pension eligibility and the tax treatment of each investment still affect a real retirement plan, but they are not silently approximated inside the result.

Progressive income tax. Australia taxes personal income at progressive rates. In 2026-27, the first $18,200 is tax-free, income from $18,201 to $45,000 is taxed at 16%, $45,001 to $135,000 at 30%, $135,001 to $190,000 at 37%, and everything above $190,000 at 45%. On top of this, the 2% Medicare levy applies to most taxable income. The marginal rate determines how much of each additional dollar you keep — and therefore how fast extra income converts into savings.

Capital gains tax (CGT) discount. If you hold an investment for more than 12 months before selling, only 50% of the capital gain is added to your taxable income. This makes long-term investing significantly more tax-efficient than short-term trading. For an investor in the 30% marginal bracket, the effective tax rate on a long-term capital gain drops to 15%.

Franking credits. Australian companies pay 25% or 30% corporate tax before distributing dividends. Shareholders receive a franking credit for the tax already paid. If your marginal tax rate is below the corporate rate, you receive a refund of the difference. In early retirement with low taxable income, fully franked dividends can effectively be tax-free or even generate a refund — boosting after-tax returns from Australian equities.

Medicare levy. The 2% Medicare levy applies to most taxable income above the low-income threshold. It is a flat percentage, not progressive, and it adds to your effective tax rate at every income level above the threshold.

Superannuation preservation age. For anyone born after 1 July 1964, preservation age is 60. Early retirees need enough accessible assets to bridge the years before super becomes available. This calculator combines the balance you enter into one portfolio; use the Super Planning tool when the accessible and super buckets need to be modelled separately.

The two-bucket approach: super and non-super

Australian retirement planning is fundamentally different from countries without a compulsory superannuation system. You effectively have two pools of money growing in parallel: your super fund (tax-advantaged but locked until 60) and your non-super investments (fully accessible but taxed at higher rates).

If you plan to retire before 60, you need enough in your non-super portfolio to cover every year of spending between your retirement date and the day you can access super. For someone retiring at 50, that is 10 years of living expenses — at $60,000 per year, roughly $600,000 in accessible investments, assuming no investment growth during drawdown (or less if you stay invested).

Once you reach 60 and access super, you switch to drawing from the tax-advantaged pool. Withdrawals from a taxed super fund are entirely tax-free after 60, making it the most efficient source of retirement income. The strategy is to deplete the non-super bridge first, then transition to super.

The split between super and non-super depends on your target retirement age. The earlier you want to retire, the larger the accessible bridge generally needs to be. Use the Super Planning tool to model that split; use this page for a quick combined-portfolio sensitivity check.

Worked example: $100,000 invested, $55,000 spending

Consider a 32-year-old with $100,000 already invested who adds $15,000 after tax each year. They want $55,000 a year of retirement spending, use a 7% nominal return, 2.5% inflation, a 4% withdrawal rate and age 67 as the Coast target.

The selected target is $1,375,000 in today's dollars. The nominal and inflation assumptions imply a 4.39% real return: (1.07 ÷ 1.025) − 1.

Under the calculator's steady-return model, the portfolio first passes the target at age 64, reaching about $1.41 million. The Coast FIRE milestone occurs at age 54: at that point, the accumulated balance could compound to the target by 67 without further contributions.

Changing only the withdrawal rate moves the target materially: 3.5% requires about $1.57 million, while 4.5% requires about $1.22 million. That is why the result shows a sensitivity range rather than presenting 25× spending as a fact.

This example uses one combined portfolio. If some of the $100,000 is super and retirement could happen before preservation age, the accessible bridge must be checked separately.

Common retirement planning mistakes

• Ignoring inflation. A $1 million target sounds large today, but in 20 years it buys significantly less. Always plan in real (inflation-adjusted) terms — this calculator does that automatically.
• Assuming constant returns. Markets do not return 7% every year. Sequence-of-returns risk means poor early returns can derail a plan even if the long-run average holds. Build a buffer above your minimum target.
• Forgetting the super access age. You cannot touch superannuation until preservation age (60 for most people). If you plan to retire at 45, you need 15 years of living expenses in accessible investments before super kicks in.
• Not stress-testing the plan. Run the calculator with lower returns (5% instead of 7%) and higher spending to see how sensitive your timeline is. A plan that only works under optimistic assumptions is not a plan.
• Treating the target as exact. Any withdrawal-rate target is a guideline, not a guarantee. Health costs, market crashes, and lifestyle changes all create variance. Use the sensitivity range and revisit the plan annually.

When to use a retirement calculator

A retirement calculator is not something you use once and forget. Certain life events should prompt a re-check to make sure your plan still holds:

• Pay rise or job change. If your investable surplus changes, update the annual amount invested to see how the timeline moves.
• Major expense change. Moving house, having children, or paying off a mortgage all shift your annual spending. Recalculate the target using the withdrawal rate you are testing.
• Market drawdown. After a significant market fall, re-run the calculator with your current portfolio balance to see the new timeline. Avoid panic — the compounding years ahead often make up the difference.
• Reaching a milestone. When you hit Coast FIRE or a specific savings target, check whether your assumptions still hold and whether you want to adjust your strategy.
• Annual review. At minimum, revisit once a year with updated balances, spending and annual contributions. Retirement planning is iterative, not a one-time exercise.
• Approaching preservation age. As you get closer to 60, model how super drawdowns interact with your non-super portfolio and potential Age Pension eligibility.
