Superannuation Calculator: Estimate Your Retirement Balance

A superannuation calculator answers one question: based on what you earn, what you have saved and how long you will keep working, roughly how much super will you have when you stop working, and how long will it last? It does that by compounding your current balance forward, adding employer and voluntary contributions, subtracting fees, tax and insurance premiums, and applying an assumed investment return each year.

This guide is for working Australians who want to sanity-check a projection rather than accept it. That includes employees covered by the Superannuation Guarantee, sole traders and small business owners who pay their own contributions, people returning from a career break, and anyone within ten years of preservation age who needs to know whether their balance supports the income they have in mind.

The important thing to understand before you start is that a superannuation calculator is a model of assumptions, not a statement of your account. Two tools can produce results tens of thousands of dollars apart from identical personal details, simply because one assumes a 6% net return and the other assumes 5%, or because one reports the result in today's dollars and the other does not. The numbers you feed in are worth more attention than the number that comes out.

What you need before you start:

• Your current total super balance across every fund, taken from your latest member statement or your myGov account linked to ATO online services.
• Your gross annual salary, and whether your employer pays super on top of it or includes it in a total package figure.
• Your employer contribution rate. The Superannuation Guarantee is 12% of ordinary time earnings from 1 July 2025, though some employers and awards pay more.
• Any salary sacrifice or personal contributions you already make, plus the annual amount.
• Your fund's investment option, its published long-term return objective, and the total annual fee and insurance premium cost.
• Your intended retirement age and a rough target annual income in today's dollars.

Gather those six inputs and the projection takes a few minutes. Skip them and the output is guesswork dressed up as a projection. The Australian Taxation Office is the authority for superannuation guarantee rates, contribution caps and eligibility rules, so check every contribution figure you enter against current ATO guidance rather than an older article or a fund brochure.

The sections below explain how the mechanics work, which assumptions drive the result, why projections run from 1 July, how fees and insurance quietly reduce a balance, how career breaks and salary sacrifice change the picture, and how to stretch a balance across a long retirement.

• A superannuation calculator projects a future balance and retirement income from your current balance, salary, contributions, investment return, fees and the years left until you retire. It is an estimate, not a promise.
• The Superannuation Guarantee rate is 12% of ordinary time earnings from 1 July 2025, and the ATO publishes the concessional contributions cap ($30,000 in 2024-25 and 2025-26) that limits how much you can add at the 15% contributions tax rate.
• Small assumption changes matter more than most people expect. A one percentage point difference in net investment return, sustained over 25 years, can move a projected balance by tens of thousands of dollars.
• Fees, insurance premiums inside the fund and years out of paid work usually matter more across 30 years than a single year of extra contributions.
• Most projection tools run from the start of the financial year, so a result you generate in April still assumes a full 12 months of contributions and earnings for that year.
• Most calculators exclude the Age Pension, insurance premiums, career breaks and partner assets unless you add them, so read the assumptions page before trusting the number.
• Keep contribution statements, notices of intent to claim a personal deduction and annual member statements. The ATO requires an acknowledged notice of intent before you can deduct a personal contribution.

A superannuation calculator is a projection model, not an account statement. It takes what you have today and rolls it forward, running the same loop once for each year between now and your retirement age. It takes the opening balance, adds contributions net of the 15% contributions tax that applies to concessional amounts, applies the assumed investment return, then deducts administration fees, investment fees and any insurance premiums. The closing balance becomes next year's opening balance. Most tools then express the final figure in today's dollars by discounting for inflation, which is why the projection often looks smaller than a raw compounding sum.

Different tools answer different questions, so check what you are actually looking at before you act on the number.

None of these outputs is a forecast. They show the arithmetic consequence of the assumptions you accept.

The inputs a projection asks for are not equally reliable. Some are known figures you can read off a statement, and others are assumptions dressed as data.

Four of those assumptions do most of the work in any projection:

• Net investment return. Usually stated after investment fees and tax. A one percentage point difference compounds heavily across 30 years.
• Inflation and wage growth. These decide whether the result is shown in today's dollars or future dollars. Today's dollars is the more useful figure for planning.
• Contribution rate. Employer contributions are calculated on ordinary time earnings at the superannuation guarantee rate set by the ATO.
• Retirement age. Each extra working year adds contributions and removes a drawdown year.

Change one assumption at a time and note the effect. That tells you which lever in your own situation is worth pulling.

The detail most tools bury is sequencing. Two people with identical average returns can finish with different balances if one suffers a poor return in the final years before retirement, when the balance is largest. A single-line growth assumption cannot show that risk, which is why a projection should be treated as a central estimate with a wide band around it.

Three settings sit inside almost every projection, and each is something you can usually change.

The fund. Most employees can choose their fund. If you do not choose, your employer generally pays into your existing stapled fund identified through the ATO, which is why many people hold one account rather than several. Multiple accounts mean multiple sets of fixed fees and premiums.

The investment option. Growth, balanced, conservative and cash options have different expected returns and different volatility. A superannuation calculator asks you to pick a return assumption that matches your option. Entering a growth-style return while sitting in a cash option will overstate your projected balance for decades.

The contribution settings. These include the compulsory employer amount, any salary sacrifice, personal after-tax contributions and personal deductible contributions. Only the concessional amounts reduce your taxable income, and they count towards the concessional cap published by the ATO.

Of the three, the investment option has the largest long-run effect, and it is also the one people most often leave on default. The arithmetic is unforgiving. On a $150,000 balance with $14,400 in annual contributions, a net return of 5% compared with 7% over 25 years produces a difference well into six figures. Model at least three options rather than one, and note the gap. That gap is the price of caution, and it is only worth paying if the volatility would otherwise push you into selling at the wrong time.

Two trade-offs are usually left out:

• Time horizon beats risk tolerance. Retirement does not end the investment period. A 65 year old may still have a 25 year horizon, so shifting entirely to cash at retirement can lock in inflation risk instead of removing risk.
• Fees compound against you the same way returns compound for you. A 0.5 percentage point fee difference has roughly the same effect over decades as a 0.5 percentage point return difference, but it is certain rather than uncertain.

Most tools model whole financial years rather than part years. When you use a superannuation calculator in March, the projection generally treats the current year as running from 1 July and assumes a full 12 months of contributions, fees and earnings.

That design choice exists for good reasons. Contribution caps, the superannuation guarantee rate and the low income super tax offset are all measured across a full financial year, and the ATO applies them on that basis. Modelling half years would require the tool to know exactly when each contribution was received by your fund.

The practical consequences are worth knowing:

• If you started work part way through the year, the tool may overstate this year's contributions.
• If you have already made a large voluntary contribution, entering it as an annual amount may double count it.
• A mid-year balance combined with full-year contributions can inflate the first projected year.

Enter your balance as at 1 July where the tool asks for it, then check the first year output against your statement.

Fees and insurance premiums are deducted from your account before compounding does its work, which is why a superannuation calculator that ignores them will always look optimistic.

Typical deductions inside a super account include a flat weekly or monthly administration fee, a percentage-based administration or investment fee, premiums for death, total and permanent disability and income protection cover, and any advice fees you have agreed to have deducted from the account.

Two points most projection tools rarely spell out:

• Flat fees hurt small balances most. A fixed annual fee is a far larger percentage drag on a $30,000 balance than on a $300,000 balance, which is one reason duplicate accounts are expensive.
• Premiums usually rise with age. Many tools hold insurance costs flat for the whole projection, understating the deduction in your fifties and sixties.

Take the fee and premium figures from your annual statement rather than accepting a tool's default, and re-run the projection with the real numbers.

Salary sacrifice redirects part of your pre-tax pay into super. The sacrificed amount is generally taxed at 15 per cent inside the fund rather than at your marginal rate, which is the source of the benefit for most people above the lowest tax bracket.

Three practical rules apply:

• Salary sacrifice, employer superannuation guarantee amounts and personal contributions you claim as a deduction all count towards the same concessional contributions cap set by the ATO. Exceeding it creates an excess contributions assessment.
• Unused cap amounts can be carried forward for up to five years if your total super balance is under the ATO threshold.
• Higher income earners may pay an additional 15 per cent Division 293 tax on concessional contributions once income plus contributions exceed the ATO threshold.

To see how a sacrifice arrangement changes your take-home pay before you commit, model the gross to net effect with a pay calculator, and check contribution deduction rules through the giving and super deductions library.

The ATO recognises several routes to a larger balance, each with its own eligibility rules and caps:

• Salary sacrifice. Pre-tax contributions taxed at 15% inside the fund, counted against the concessional cap of $30,000 for 2024-25 and 2025-26 alongside employer contributions.
• Personal deductible contributions. You must lodge a notice of intent to claim with your fund and receive an acknowledgement before you claim the deduction and before you lodge your return.
• Carry-forward concessional contributions. If your total super balance was under $500,000 at 30 June of the previous year, you can use unused cap amounts from the previous five financial years.
• Non-concessional contributions. After-tax amounts within the annual cap, with a bring-forward option for eligible people under 75.
• Government co-contribution and spouse contribution offset. Income-tested support for lower income earners and their partners.

The tax treatment of contributions sits alongside the other claims you make at lodgement, and our giving and super tax deductions guide covers where personal contributions fit in a return.

Time out of paid work is the single largest cause of gaps between projected and actual balances, and most default projections assume unbroken employment to retirement.

The effect is compounding, not linear. Contributions missed at 30 have three decades to grow; contributions missed at 58 do not. A five year break in your thirties can cost far more at retirement than the contributions themselves were worth.

Points worth modelling:

• Unpaid parental leave. Employer superannuation guarantee contributions generally stop while there are no ordinary time earnings.
• Part-time return. Contributions fall with hours, so model reduced salary years rather than a clean on or off switch.
• Fees keep running. Administration fees and insurance premiums continue to be deducted during a break.

Enter the break as reduced or zero salary years, then test whether higher contributions before or after the break close the gap more efficiently.

Read the assumptions page before you trust the output. Most projection tools assume continuous full-time employment to retirement, no periods of unpaid leave, a flat real salary growth rate, a constant investment return, and no change of fund. They usually exclude the Age Pension, insurance premiums, government co-contributions, spouse contributions and divorce or illness events. Any one of those omissions can move a projection materially.

Tips and common mistakes:

• Do not enter a total package salary as if super were paid on top of it.
• Include every fund. Lost accounts can be found through ATO online services.
• Do not ignore insurance premiums, which are deducted from your balance monthly.
• Re-run the projection after any pay rise, career break or change of fund.

Work backwards from the income you want rather than forwards from the balance you have. Decide on an annual retirement income in today's dollars, then test what balance supports it.

A workable method:

1. Write down your expected annual spending in retirement, separating essentials from discretionary items.
2. Subtract any Age Pension you may be eligible for, keeping in mind that eligibility depends on the income and assets tests administered by Services Australia.
3. The remainder is what your super needs to fund each year.
4. Test how long the balance lasts at that drawdown rate, allowing for investment returns continuing during retirement.

Run three scenarios: a lower return, your central assumption, and a higher return. If the plan only works in the optimistic case, the plan needs changing, not the assumption.

Review the projection annually, ideally when your fund statement arrives.

Longevity is a drawdown question, not an accumulation question. Once you move into a retirement phase income stream, investment earnings in that account are generally tax free, and the ATO sets minimum annual drawdown percentages that rise with age, starting at 4% for people under 65 and increasing in bands through to 14% at 95 and over. You can withdraw more than the minimum, and that decision is what determines how long the balance lasts.

How long will $1,000,000 in super last? If you draw $60,000 a year from a $1,000,000 balance earning 5% net after fees, the balance runs for roughly 25 years before exhausting. Draw $80,000 a year on the same return and it lasts closer to 16 years. Draw $50,000 and the earnings largely cover the withdrawal, so the balance can persist for 30 years or more. The relationship between drawdown rate and duration is not linear, which is why a 10% change in spending shifts the end date by years rather than months.

How long could my super savings last? Run the same three drawdown scenarios on your own balance, then add two adjustments most tools ignore. First, spending is rarely flat. Travel and renovation spending is front-loaded in the first decade, while health costs rise later. Second, part Age Pension entitlement typically begins as your assets fall below the relevant thresholds, so the amount you need to draw from super often reduces in later years.

Practical levers that extend the balance:

• Delay full retirement by two or three years, which adds contributions and removes drawdown years at the same time.
• Keep a growth allocation on the portion of the balance you will not touch for a decade.
• Hold two to three years of planned withdrawals in a defensive option so you are not forced to sell growth assets in a downturn.
• Review fees, because in drawdown they are paid out of a shrinking balance.

Re-run a superannuation calculator every year or two in drawdown, because each actual return, fee change and spending decision shifts the projected end date more than any single assumption you set at the start.

Benchmarking is useful for direction, not for grading. Median balances published by the Australian Bureau of Statistics and the ATO's taxation statistics show a wide spread at every age, largely driven by income, time out of the workforce and whether someone made voluntary contributions early. Women's median balances sit consistently below men's at most age brackets, mainly reflecting career breaks and part-time years rather than different investment choices.

A more useful comparison than the national median is your own trajectory. Take your current balance, project it to your intended retirement age, then convert that figure into an annual income using a sustainable drawdown rate. If the resulting income falls short of what you want to spend, the gap tells you how much extra to contribute each year. That is a concrete number you can act on, unlike a percentile ranking.

Projection tools give general information. They do not know your debts, your partner's balance, your health, your Age Pension position or your estate planning intentions. Consider licensed personal advice when the decision is hard to reverse or has tax consequences you cannot easily model.

Common trigger points include:

• Consolidating accounts where one holds insurance cover you may not be able to replace.
• Making large concessional contributions near the cap, including catch-up contributions from unused cap amounts.
• Planning a transition to retirement income stream or a retirement date within five years.
• Receiving an inheritance, redundancy payment or business sale proceeds.
• Deciding on binding death benefit nominations.

Financial advisers must be licensed and listed on the ASIC financial advisers register. For tax questions arising from contributions, a registered tax agent or the ATO is the right source.

Eligibility for employer super rests on the Superannuation Guarantee, which is 12% of ordinary time earnings from 1 July 2025, while eligibility to claim a personal contribution depends on lodging a notice of intent and receiving your fund's acknowledgement. The calculation itself compounds your balance forward with contributions net of the 15% contributions tax, then subtracts fees and premiums and applies an assumed return, so the investment option and the fee level drive most of the variance in the result. On records, keep member statements, contribution confirmations and acknowledged notices of intent. Deductit publishes plain-language deduction guides and tax deduction calculators you can use alongside your fund's figures. This is general information, not personal tax advice, and Deductit does not lodge returns.

How do the tools work?

These tools work by projecting your balance forward one financial year at a time: they add contributions, deduct contributions tax, fees and insurance premiums, then apply an assumed net investment return. Most fund and government tools work from standardised default assumptions you can override, which is why two calculators can produce different results from identical details.

In practical terms, a superannuation calculator can show you a projected retirement balance, an estimated annual retirement income, how long your savings might last, and the lifetime cost of fees and insurance premiums deducted from your account.

How can I calculate how much super I will have?

Start with four inputs from your most recent member statement: your balance as at 1 July, your annual employer and voluntary contributions, your total fees and insurance premiums, and your investment option. Enter your gross salary and intended retirement age, then choose a net return assumption that matches your investment option rather than the tool's default. Run the projection in today's dollars so the result is comparable to your current spending. Repeat with a return one percentage point lower to see the downside case, and check the first projected year against your statement to confirm the tool has not double counted a contribution.

How much super do I need to retire on $70,000 a year?

There is no single figure, because the answer depends on your other assets, your Age Pension eligibility and whether you own your home outright. As a method rather than a number, take $70,000, subtract any Age Pension you expect to receive under the Services Australia income and assets tests, and treat the remainder as the amount your super must fund each year. With no Age Pension at all, most projections point to roughly $1.1 million to $1.4 million, depending on your assumed net return and how long the money must last. Homeowners generally need less than renters, and couples generally need less per person than singles.

How long will $1,000,000 in super last?

At $60,000 a year and a 5% net return, $1,000,000 lasts roughly 25 years. At $80,000 a year it lasts about 16 years, and at $50,000 a year earnings nearly cover withdrawals, so it can run 30 years or more. Fees and poor returns in the early years shorten these estimates, and a part Age Pension in later years can extend them.

Can I retire at 60 with $500,000 in super?

It depends on the income you need and how long the money must last. Preservation age is 60 for anyone born on or after 1 July 1964, so access at 60 follows a condition of release. $500,000 drawn down at $40,000 a year with modest investment earnings runs for about 17 years, while $30,000 a year stretches past 25 years with a part Age Pension. The same balance supporting $70,000 a year will run down much faster. Many people at 60 also remain outside Age Pension age, so the early years must be funded entirely from savings. Model those pre-pension years separately.

How much super do I need for $100,000 a year?

Again, work backwards. Subtract any Age Pension entitlement, though at that income level most people receive little or none, then calculate the balance required to sustain the remainder across your expected retirement length at a conservative net return. Because $100,000 a year sits well above the pension threshold, the projection is far more sensitive to investment returns and to sequencing risk in the first few years of retirement. Test a poor return in year one and see whether the plan still holds. If it does not, extending your working life or lifting concessional contributions within the ATO cap are the two most effective adjustments.

How can I estimate my Age Pension eligibility?

You can estimate your Age Pension eligibility using the Services Australia payment and income estimators, which apply the current age, residency, income test and assets test rules to your own figures. Because thresholds are indexed twice a year, check the published rates at the date you run the estimate, and remember that super in accumulation phase is excluded from the assets test until you reach Age Pension age.

Which professional should I talk to about my super?

The relevant people are a licensed financial adviser for personal retirement strategy, a registered tax agent for the tax treatment of contributions, and your fund for balance and insurance details. Financial advisers must be licensed and listed on the ASIC financial advisers register. A medical practitioner has no role in super projections; medical evidence only becomes relevant for early release of super on compassionate or permanent incapacity grounds, where the ATO and your fund set the conditions and require supporting documentation.

Is there a cost to use these tools?

No. The ATO, Moneysmart and Services Australia calculators referenced in this guide are free, and Deductit's deduction guides and calculators are free to use as well. Paid personal advice is a separate service from a free projection tool.
