This is one of the most common questions Australians in their 50s bring to a financial planner. You’ve got some extra money each month, retirement is getting closer, and you’re staring down two very different directions. Put more into super and let compound growth do its thing. Or hammer the mortgage and walk into retirement debt-free.
The honest answer is: it depends. And the reason it depends is not wishy-washy fence-sitting. It’s because the right answer genuinely shifts based on your income, your interest rate, how far you are from retirement, and frankly, how you sleep at night.
Here’s how to actually think through it.
The Numbers Case for Super
On a pure spreadsheet basis, super usually wins for anyone on a decent income. Here’s why.
When you make an extra mortgage repayment, you’re using after-tax dollars. If you earn $100,000 and want to put $10,000 extra toward your home loan, you’ve already paid roughly $3,200 in income tax on that $10,000 to have it in your hands. You’re paying down debt with money that’s already been taxed.
When you salary sacrifice into super, that same $10,000 goes in before tax. It’s taxed at 15% inside the fund instead of your marginal rate. At $100,000, your marginal rate is 34.5% (including the Medicare levy). So salary sacrificing $10,000 costs you about $6,550 in take-home pay, versus $10,000 out of pocket for the mortgage repayment. You’re putting more to work for less.
That gap compounds over years, particularly for higher income earners. At $120,000 or above, the tax saving on salary sacrifice is significant enough that super comes out well ahead mathematically, even before you account for investment returns.
As Scott and Phil covered in Episode 5 of the Wealthlab Podcast: “Should You Pay Off Your Mortgage With Super at 60?”, the spreadsheet answer is often to keep super, not pay off the mortgage. But the spreadsheet doesn’t live in your house, and the emotional side of this decision is completely real.

The Numbers Case for the Mortgage
The case for paying down the mortgage is simpler than people think: it’s a guaranteed return.
If your mortgage rate is 6%, every extra dollar you put on the loan saves you 6% interest. That’s a certain, risk-free, after-tax return. Super returns are not guaranteed. A growth fund averaging 7 to 8% long-term is reasonable to expect, but those returns come with volatility. In a bad year or two before retirement, a market downturn can hit your balance hard in a way that paying off debt never can.
Phil put it plainly on the podcast: “Financial planning is a funny thing. You’ve got one answer on a spreadsheet, but you’ve got the other answer that takes into account living, breathing people with emotions.”
The closer you are to retirement, the more that matters. A 58-year-old with a $150,000 mortgage balance and eight years on the loan is in a different position to a 42-year-old with a $450,000 mortgage and 22 years left. For the person close to retirement, the certainty of being debt-free by 60 or 62 may be worth more than the theoretical super advantage.
There’s also an access issue that most calculators ignore. If you put extra money into super at 48 and then face an emergency, that money is locked away until you’re 60. Extra mortgage repayments in a redraw account or offset are accessible. That liquidity matters, particularly when you have kids, a variable income, or unexpected costs ahead.
The Factor Most Australians Completely Miss: The Age Pension
Here’s something the generic mortgage-vs-super calculators almost never include, and it changes the picture significantly.
Your family home is completely exempt from the Age Pension assets test, regardless of its value. Your super is not.
This means that money sitting inside super at 67 is assessed by Centrelink under both the assets test and the income test (via deeming). Money you’ve used to pay off your home sits inside an exempt asset.
For some Australians, particularly those with moderate super balances near the Age Pension thresholds, having more home equity and less super can actually increase their Age Pension entitlement. The extra pension income can more than offset the lower super balance over time.
This is a nuanced calculation that genuinely requires someone to look at your specific numbers. But it’s a real factor, and it’s one reason why “always max out super, the spreadsheet says so” isn’t always the right answer for someone in their mid-50s approaching retirement age.
Phil and Dan walked through exactly this kind of Age Pension interaction with real case studies in Episode 10 of the Wealthlab Podcast: “How the Age Pension Really Works”. If you’re within 10 years of retirement and still have a mortgage, it’s worth understanding this before you make the call.
A Simple Framework: Where Are You?
Rather than one universal answer, think about it by life stage.
In your 30s and early 40s with a large mortgage:
Super is likely the better use of extra money if your income is above $60,000, because the tax saving on salary sacrifice is meaningful and you have decades of compounding ahead. That said, if you’re stretched thin with a large loan, young children, and no emergency buffer, the liquidity argument for keeping accessible funds in an offset account is strong. An offset account is not paying off the mortgage outright but it achieves a similar interest saving while keeping the cash accessible.
In your mid to late 40s:
This is often the sweet spot for balancing both. The mortgage is smaller, income is often at or near its peak, and the kids are becoming more financially independent. Maximising the concessional contributions cap ($30,000 per year including your employer’s 12%) while making regular mortgage repayments tends to work well here. If you haven’t been maximising contributions in previous years and your balance is under $500,000, catch-up concessional contributions let you use unused cap space from the past five years, potentially putting a meaningful lump sum into super while still chipping away at the loan.
In your 50s with retirement in sight:
The calculus changes. Two things become more important: being debt-free before you stop earning, and understanding how your assets will interact with the Age Pension. Many Australians in this position are better served by a specific strategy: use salary sacrifice to fill the concessional cap each year for the tax saving, while directing other extra cash toward the mortgage to clear it before retirement. The goal is entering retirement with no debt and a meaningful super balance, not sacrificing one entirely for the other.
At 60 with a mortgage remaining:
As Scott said in Episode 5, this is where it gets genuinely personal: “I take the opposite perspective. I like to see people have a little bit of juice in the tank.” The spreadsheet might say keep super at 8% while the mortgage is at 6%. But walking into retirement with a $200,000 debt on a fixed income is a different kind of stress. For many people, the emotional value of being debt-free at 60 is worth a lot. If paying off the mortgage at 60 means drawing from super to do it, that needs careful modelling to avoid unintended tax consequences or Age Pension impacts. But it’s a legitimate choice.
The Offset Account: The Middle Path
One option that gets too little attention in this debate is the offset account.
An offset account attached to your mortgage saves you interest at your full mortgage rate, just like an extra repayment. But the money stays accessible. You haven’t locked it away in super, and you haven’t permanently reduced your loan balance in a way that’s hard to reverse.
For Australians in their 40s who want the interest saving of paying down the mortgage but are worried about locking cash away, a well-funded offset account can be an excellent middle path. It’s not as tax-effective as salary sacrifice into super for high earners, but it’s flexible, it reduces interest daily, and it’s there if you need it.
Frequently Asked Questions
Is it better to pay off my mortgage or contribute extra to super?
For higher income earners (above $60,000), salary sacrifice into super usually wins mathematically because of the tax saving on concessional contributions. For people close to retirement or with interest rates near or above likely super returns, paying off the mortgage becomes more attractive. The Age Pension interaction also matters: your home is exempt from Centrelink’s assets test but super is not, which can affect Age Pension eligibility.
At what age should I prioritise super over my mortgage?
There’s no universal age, but the mid-to-late 40s is typically when super starts to make more sense as the priority, because the mortgage is smaller, retirement is closer, and the super lock-in period is less of a concern. In your 50s, the goal is often to do both: use salary sacrifice for the concessional cap and direct remaining extra cash to clear the mortgage before retirement.
Can I use my super to pay off my mortgage?
Yes, once you meet a condition of release (typically retiring after age 60 or turning 65). Withdrawals from a taxed super fund after age 60 are tax-free. But drawing super specifically to pay off the mortgage at or near retirement needs careful planning, as it can affect Age Pension eligibility depending on the timing and the assets involved.
Does an offset account count as paying off the mortgage?
Not technically, but it achieves the same interest saving. Every dollar in an offset account reduces the loan balance on which interest is calculated, saving you interest at your mortgage rate. Unlike an extra repayment, the money stays accessible. For people who want the interest saving but prefer to keep cash available, an offset account is often the best of both options.
Does paying off my mortgage help my Age Pension?
It can. Your principal home is completely exempt from the Centrelink assets test regardless of its value. Super, once you reach Age Pension age, is assessed under both the assets and income tests. For some Australians near the Age Pension thresholds, having more equity in a paid-off home and less in super can actually increase their pension entitlement. This is one of the most overlooked factors in the mortgage-vs-super debate.
What is the concessional contributions cap for 2025/26?
$30,000 per year, including your employer’s 12% Superannuation Guarantee. If your employer pays $9,600 SG (12% of $80,000), you have $20,400 of concessional cap remaining for salary sacrifice. If you’ve had unused cap space in the past five years and your total super balance is under $500,000, you may be able to use catch-up contributions on top of this.

What’s the Right Answer for You?
There’s no universal answer here, and anyone who gives you one without knowing your income, your mortgage balance, your super balance, how far you are from retirement, and whether your partner has their own super isn’t giving you real advice.
What there is, is a way to think about it that actually fits your situation rather than a generic spreadsheet.
