The short answer? For many Australians on middle to higher incomes with a decade or more until retirement, salary sacrifice into super tends to win on the maths, because of the tax break on the way in. For those close to retirement, on lower marginal tax rates, or who simply sleep better without debt, extra mortgage repayments can genuinely be the better call. And the Age Pension interaction, which almost every generic calculator ignores, can swing the answer by more than the tax and returns combined.
What has changed in 2026 is the gap between the two options. With mortgage rates back around 6% and the bottom tax rate falling, the contest is closer than it has been in years. This guide runs the current numbers on both sides, the pension mechanics most people miss and the version of this decision that lands at 60, when super becomes accessible and the question turns real.
The 2026 rate environment has tightened the race
Two numbers set the stage. The Reserve Bank lifted the cash rate three times in 2026 to 4.35%, putting average owner-occupier variable rates around 5.9%, and closer to 6.5% at the big four. Meanwhile the median growth super fund returned 9.5% in the 2025-26 financial year, its fourth straight strong year, with a long-run average of about 8% a year since compulsory super began. Sources: RBA lenders’ rates via Mozo; Chant West. Current as at September 2026, and mortgage rates in particular move often.
On paper, 8% expected beats 6% owing. But they are not the same kind of number. Paying down a 6% mortgage is a guaranteed, after-tax, zero-risk return. Super’s 8% is a long-run average that included a 26% drawdown during the GFC and a negative year in 2022. The narrower the gap, the more the guarantee is worth, and right now the gap is the narrowest it has been in a while. That is the honest starting point, and it is why this decision deserves current numbers rather than a rule of thumb from the 2% mortgage era.
The case for super first
The engine here is tax. Salary sacrifice and deductible contributions go into super after 15% contributions tax instead of your marginal rate. For someone on the 30% marginal rate (plus Medicare levy), that is roughly 17 cents saved per dollar contributed. At 37%, roughly 24 cents. Every $10,000 of salary directed to super puts about $8,500 to work, where the same $10,000 taken as salary leaves closer to $6,800 to throw at the mortgage. The super dollar starts 25% ahead before it earns anything.
One 2026 wrinkle worth knowing: the bottom marginal rate fell to 15% from 1 July 2026, which means for income under roughly $45,000 the tax advantage of salary sacrifice has largely evaporated. The strategy earns its keep from the 30% bracket up.
The contribution caps for 2026-27: $32,500 in concessional contributions a year (including employer contributions), plus carry-forward of unused caps from the previous five years if your total super balance was under $500,000 at 30 June 2026. Source: ATO contribution caps. Current as at September 2026. We covered how the 50s become the power decade for this in How much super should I have at 50?
The trade-off is access. Money in super is locked until a condition of release, generally age 60. A 45-year-old choosing super over the mortgage is choosing 15 years of no access, which is exactly why the answer shifts with age.
The case for the mortgage first
Three arguments, and none of them are irrational:
The return is guaranteed. Every dollar off a 6% mortgage earns a risk-free 6% after tax. No sequencing risk, no negative years, no waiting for markets to recover.
The money stays reachable. Extra repayments in a redraw or offset remain available for emergencies, renovations or a job loss. Super does not.
Debt-free is a feeling, not just a number. Scott and Phil covered this on the podcast episode about paying off the mortgage with super, including the stat that around 40% of Australians in their late 50s still carry mortgage debt heading toward retirement. The spreadsheet regularly says keep the money invested, and plenty of people take the other path anyway, because the relief is worth more to them than the margin.
The Age Pension wildcard
Here is the part generic calculators skip, and it can outweigh everything above. The family home is exempt from the Age Pension assets test regardless of its value. Super is fully assessable from Age Pension age. So a dollar sitting in super at 67 counts against your pension. The same dollar inside your paid-off home does not.
The current settings, from 20 September 2026: a homeowner couple’s pension reduces by $3 a fortnight for every $1,000 of assessable assets above $499,000, cutting out at $1,121,000 ($333,000 and $745,750 for singles). Source: Services Australia. Current as at September 2026. These figures are set by the Australian Government and are typically updated each March, July and September.
Run that through a real scenario. A couple at 67 with a $300,000 mortgage and $800,000 in super sits in the taper zone. Using $300,000 of super to clear the mortgage moves that money from an assessed asset into an exempt one, and at the taper rate that can lift their Age Pension by up to $23,400 a year, every year, indexed. That is before counting the interest they are no longer paying.

Individual outcomes will vary based on personal circumstances, interest rates, investment returns, tax positions and current government policy. This is general information, not personal advice.
Not everyone benefits. A couple well under the assets test threshold gains no pension from the move, and a couple far above it gains nothing either. The zone where it matters is wide, though, and it is the single most common thing we find missing when people show us the mortgage-versus-super analysis they have done themselves. Structuring around these tests is the day job of our pension and Centrelink advice team.
The decision at 60: paying it off with super
At 60, this stops being theoretical. Once a condition of release is met, super withdrawals are tax-free, and clearing the mortgage in one hit becomes a live option. Scott and Phil dedicated a full episode to exactly this:
The example they worked through: a 60-year-old with a $300,000 mortgage at 6%. The spreadsheet often says keep the money in super earning more than the mortgage costs. Phil’s take on the episode: “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.” Scott pushed the other way: “I take the opposite perspective. I like to see people have a little bit of juice in the tank.” Both are right, which is the point. The maths is one input. Cash flow certainty, the pension position at 67 and how the debt feels at 3am are the others.
The mechanics of lump sum withdrawals, conditions of release and what happens to insurance held inside super are covered in our superannuation withdrawal rules guide.
A rough map by life stage
20 years or more from retirement: we generally find the tax and compounding maths favours super for surplus dollars, provided the mortgage is comfortably serviceable and there is a cash buffer. Locking money away for decades is the price.
10 to 15 years out: many people run both, splitting surplus between extra repayments and salary sacrifice, aiming to land at 60 with the mortgage near zero and the carry-forward caps used up.
Inside 5 years or at 60: the Age Pension test starts to dominate the analysis, and the emotional value of entering retirement debt-free is at its highest. This is where the decision most rewards being modelled properly rather than guessed.
Whether any of these patterns suits your situation depends on individual factors: income, balance, loan size, risk tolerance and what retirement is meant to look like. Want to see how your own numbers interact? Run them through the free Wealthlab super calculator for a quick picture.
Frequently asked questions
Is it better to pay off the mortgage or add to super? It depends mostly on your marginal tax rate, your distance from retirement and your Age Pension position at 67. Higher earners with time on their side often come out ahead in super due to the tax concession. Those close to retirement or on the 15% marginal rate often find the guaranteed saving of mortgage repayments just as strong, with none of the market risk.
Can I use my super to pay off my mortgage at 60? Generally yes, once you have met a condition of release such as retiring or ceasing an employment arrangement. Withdrawals from a taxed fund after 60 are tax-free. The trade-off is a smaller balance generating retirement income, weighed against being debt-free and potentially a higher Age Pension at 67.
Does paying off the mortgage increase the Age Pension? It can, significantly. The family home is exempt from the assets test while super is assessable, so moving money from super into the home reduces assessable assets. For a couple in the taper zone, clearing a $300,000 mortgage can lift the pension by up to around $23,400 a year at current settings.
How much tax do I save with salary sacrifice? Contributions are taxed at 15% instead of your marginal rate. On the 30% rate plus Medicare levy, that is roughly 17 cents per dollar; on 37%, roughly 24 cents. Below about $45,000 of income the marginal rate is now 15%, so the saving is minimal. The 2026-27 concessional cap is $32,500 including employer contributions.
Is a 6% mortgage worth paying off early? Paying down a 6% loan is a guaranteed after-tax return of 6%, which is competitive with the long-run average super return once risk is accounted for. Whether it beats super for you depends on the tax saving on contributions and your pension position, which is why the answer differs person to person.
What about investing outside super instead? Some people borrow against the home to invest while still working, a strategy called debt recycling. It adds risk and complexity, and Scott and Phil walked through both the upside and a GFC-era cautionary tale in the episode on borrowing to pay off your home sooner. It suits a narrower group than the two options above.
Your next step
The right answer to mortgage-versus-super is genuinely different for each household, and it depends on your income, mortgage balance, super balance, distance from retirement, and whether your partner has their own super and income. Anyone offering a universal answer without knowing those specifics is offering a generic view, not real advice.
