Career breaks are a normal part of working life — raising children, caring for parents, studying, travelling, or recovering from illness. But in Australia’s superannuation system, time out of the workforce has a price that is much larger than most people expect. You do not just lose the super contributions for the years you are away. You lose decades of compounding on those contributions, which is why a break taken in your thirties can cost six figures by retirement.
This guide puts real numbers on that cost, explains why the timing of your break matters so much, and sets out the practical ways to claw the money back — including some that only work if you act within a few years. Model your own situation with our free super calculator.
Why a career break costs more than the missing contributions
Employers pay superannuation guarantee (SG) at 12% of ordinary time earnings (since 1 July 2025). When you stop working, those contributions stop too. That part is obvious. What is less obvious is that each missed contribution would have grown for every remaining year until retirement — so a dollar of super missed at age 35 is worth far more at age 67 than a dollar missed at age 60.
The formula is simple compound growth: future value = contribution × (1 + return) raised to the power of years remaining. At a 5% net annual return, $1 contributed at age 35 is worth about $4.76 at age 67. At age 30, it is worth about $6.08. This is why early breaks are so expensive, and why catching up later — even with larger contributions — never fully replaces early money.
Worked example: a 3-year break at 35 on $70,000
Take an employee earning $70,000 who takes three years out of the workforce at ages 35, 36 and 37, then returns to work. Employer SG at 12% would have been $8,400 a year, or $25,200 across the three years.
| Missed year (age) | Missed SG contribution | Years to age 67 | Value at 67 (5% net return) |
|---|---|---|---|
| 35 | $8,400 | 32 | $39,985 |
| 36 | $8,400 | 31 | $38,081 |
| 37 | $8,400 | 30 | $36,268 |
| Total | $25,200 | — | $114,334 |
The headline: $25,200 in missed contributions becomes roughly $114,000 missing at retirement. The compounding — about $89,000 — is more than three times the contributions themselves. And this model is conservative: it assumes no wage growth, no increase in the SG rate, and no catch-up contributions. With wage growth, the real cost is higher.
How the cost changes with age and length
Two things drive the cost: how long you are out, and how young you are when it happens.
| Scenario (salary $70,000, SG 12%, 5% net return) | Missed contributions | Approximate cost at 67 |
|---|---|---|
| 1 year out at age 30 | $8,400 | $51,100 |
| 3 years out at age 35 | $25,200 | $114,300 |
| 5 years out at age 30 | $42,000 | $232,000 |
| 5 years out at age 45 | $42,000 | $111,700 |
| 5 years out at age 55 | $42,000 | $68,600 |
The pattern is stark: five years out at 30 costs roughly three times as much at retirement as five years out at 55, even though the missed contributions are identical. This is not an argument against taking a break — it is an argument for planning the recovery, especially for younger workers who have the most to lose and the most time to fix it.
Note that these figures are illustrative: actual returns vary, fees apply, and wages usually grow over a career. But the direction and scale are robust — industry and government modelling consistently finds that multi-year breaks in early career reduce retirement balances by six figures for middle-income earners.
What softens the blow (and what does not)
Super on government Paid Parental Leave
Since 1 July 2025, the government pays a 12% superannuation contribution on government-funded Paid Parental Leave, paid by the ATO into your fund after the end of the financial year. For a child born or adopted on or after that date, this covers the paid parental leave period (26 weeks from 1 July 2026) — but not any additional unpaid leave you take beyond it. See our guide to super on parental leave pay for the details.
Employer-paid parental leave
Many employers continue to pay SG on employer-funded paid parental leave, because those payments are ordinary time earnings. Check your agreement: if your employer pays 12 weeks of paid parental leave, SG should normally continue during those 12 weeks.
Part-time return
Returning part-time softens the blow proportionally: SG is paid on your actual ordinary time earnings, so three days a week still earns 60% of full-time SG. A part-time return beats a longer full break on super, even though the cash pay is lower.
What does not help
Unpaid parental leave beyond the paid period attracts no SG from anyone — not your employer, not the government. Career breaks for study, travel or caring for adult relatives similarly attract no SG unless you make voluntary contributions yourself. And the age pension does not compensate for a lower super balance dollar-for-dollar: it is means-tested, so a smaller balance may increase your part-pension, but you still end up with less total retirement income.
How to claw it back: five strategies
1. Carry-forward concessional contributions
If your total super balance is under $500,000, you can carry forward unused concessional cap amounts for up to five years. The annual concessional cap is $30,000 (2025–26), which includes your employer’s SG. After a break, you may have several years of unused cap banked — allowing you to make large deductible contributions in the years after you return, when your income is higher. This is the single most powerful catch-up tool, but the five-year expiry means you cannot leave it indefinitely.
2. Salary sacrifice on your return
Sacrificing part of your salary into super is taxed at 15% in the fund instead of your marginal rate. On a $90,000 salary (marginal rate 30% + 2% Medicare levy), sacrificing $10,000 a year saves about $1,700 in tax while adding $8,500 net to super. Sacrificing consistently for a few years after a break can close a large part of the gap.
3. Spouse contributions and super splitting
If your partner keeps working while you are on a break, they can split up to 85% of their concessional contributions to your fund each year, keeping your balance growing even while you earn nothing. A spouse contribution of up to $3,000 a year can also attract a tax offset of up to $540 if your income is below $37,000 — a small but real boost during low-income years.
4. Voluntary contributions during the break
Even small contributions during a break are disproportionately valuable because they compound for the longest. $100 a month during a three-year break is $3,600 in contributions — worth roughly $16,000 at retirement if started at 35. If your income is low, the government co-contribution may add up to $500 a year on top of your own after-tax contributions.
5. Check your fund and insurance
During a break, super fund fees continue and insurance premiums may keep being deducted — sometimes eroding a small balance. Check whether your insurance cover remains appropriate and whether contributions have stopped triggering any account changes. Also confirm your fund has your current details so statements and ATO correspondence reach you.
The gender gap connection
Career breaks are the largest single driver of the gender super gap in Australia: women retire with substantially less super than men on average, largely because they take more time out for caring responsibilities and return part-time more often. The introduction of super on government Paid Parental Leave from 1 July 2025 is a genuine step towards closing that gap, but it covers only the paid leave period — the longer unpaid period and subsequent part-time years remain uncovered. For couples, planning the break together — including super splitting and spouse contributions — is one of the highest-value financial conversations a household can have.
Frequently asked questions
Does my employer have to keep paying super during unpaid leave?
No. SG is payable on ordinary time earnings actually paid. During unpaid leave there are no earnings, so no SG is due — unless your agreement or contract promises otherwise.
Can I make super contributions while on a break with no income?
Yes. Anyone under 75 can make voluntary contributions to their fund, subject to caps. You can also be eligible for the government co-contribution if you meet the income and work tests, and your spouse can make spouse contributions for you.
How long do I have to use carry-forward cap amounts?
Unused concessional cap amounts expire after five years, and you can only use them if your total super balance is under $500,000 at the end of the previous financial year. Check your available cap in myGov before making large contributions.
Is it better to contribute during the break or after I return?
Every year earlier is worth more because of compounding, so contributing during the break wins if you can afford it. But contributing after you return — especially via tax-deductible salary sacrifice at a higher marginal rate — is still highly effective and far better than not catching up at all.
Does a career break affect my age pension?
Indirectly. A lower super balance may increase any part age pension you receive, because the pension is means-tested on assets and income. But total retirement income is still lower than it would have been with the extra super, so the pension only partly offsets the loss.
What if I never return to full-time work?
Part-time SG still accumulates, and voluntary contributions, spouse contributions and catch-up concessional contributions all remain available. The key is to keep contributing something — a part-time balance that keeps growing beats a frozen balance being eroded by fees.
The bottom line
A career break is not free in super terms: three years out at 35 on $70,000 costs roughly $114,000 by retirement, and five years out at 30 costs roughly double that. The damage comes mostly from lost compounding, not lost contributions — which is why early action matters more than large action later. If a break is ahead of you, plan the recovery now: check your carry-forward cap, talk to your partner about splitting, and consider even small voluntary contributions during the break. If the break is behind you, the same tools still work — just start sooner. Run your own numbers through our super calculator to see what your break is worth and what catching up would take.
