A generation ago, retiring with the mortgage still owing was unusual. It is now common. People buy later, upgrade mid-career, redraw for renovations or to help adult children, and arrive at 65 with a balance still outstanding.
The obvious solution is to take a lump sum from super and clear it. Whether that is the right move is genuinely arguable, but most of the argument you will read online is focused on the wrong variable.
The usual framing compares your mortgage interest rate against the return you expect inside super. That comparison is reasonable in your forties. At retirement, for most Australians, something else matters considerably more.
First, can you actually access it?
Superannuation is preserved until you meet a condition of release. Preservation age is now 60 for everyone.
From 60, you can access your super if you have genuinely retired, or if you cease an employment arrangement. From 65 you have full access regardless of whether you are still working.
Once you are over 60 and drawing from a taxed source, which covers the overwhelming majority of Australians, withdrawals are tax free. There is no tax cost to taking a lump sum and putting it into the mortgage.
That absence of a tax bill is exactly why people assume the decision is simple. It is not, because the cost of this decision shows up somewhere else entirely. Our article on what happens to your super when you retire covers the access rules in more detail.
The factor that usually decides it
The Age Pension is assessed under an assets test and an income test, and Services Australia applies whichever produces the lower payment.
Two features of the assets test matter enormously here. Your family home is exempt from the assets test regardless of its value. Your superannuation, once you reach Age Pension age, is assessable.
Between the full-pension threshold and the cut-off, the pension reduces by $3 per fortnight for every $1,000 of assessable assets above the threshold. Annualised, that is $78 a year for each $1,000.
Read that as a rate and it becomes striking. It is an effective 7.8% per year. Every $1,000 you hold above the threshold costs you $78 of pension, every year, for as long as you remain in that zone.
Now apply it to the mortgage question. Using $100,000 of super to pay down the home loan removes $100,000 from your assessable assets and adds it to an asset that is not assessed at all. If you sit inside the taper zone, that transaction is worth roughly $7,800 a year in additional Age Pension.
No conservative investment produces a reliable 7.8%. That is why, for households positioned in the taper zone, clearing the mortgage frequently wins by a wide margin, and why the interest rate comparison is close to a side issue.
You also stop paying the mortgage, which is a separate benefit on top.
When the taper argument does not apply
This is the part that generic articles omit, and getting it wrong is expensive.
The 7.8% only exists inside the taper zone. Three positions produce three different answers.
If your assessable assets are below the full-pension threshold, you are already receiving the full pension and reducing your assets further gains you nothing in pension terms. Clearing the mortgage may still be right for cash flow or peace of mind, but the pension argument is absent, and depleting your liquid savings when you are already on a full pension can leave you dangerously short of reserves.
If your assessable assets are well above the cut-off, currently $733,500 for a single homeowner and $1,102,500 for a couple as at 1 July 2026, you receive no pension and clearing the mortgage will not create one unless the paydown is large enough to bring you back under the cut-off. For someone with $1.6 million in super, using $200,000 to clear the mortgage changes nothing on the pension front. The decision reverts to the ordinary comparison between the loan rate and the tax-free earnings you give up inside a pension account.
If you are inside the taper zone, or a paydown would bring you into or under it, the arithmetic above applies with full force. This is where the largest gains sit, and it is also where precision matters, because paying down more than necessary can push you below the full-pension threshold where the extra dollars stop working for you.
The thresholds shift each 20 March and 20 September, so check current figures rather than relying on any published example, including this one.
The cash flow effect people undercount
Clearing the mortgage does more than change a balance sheet. It removes a fixed obligation from a household whose income has just become far less flexible.
If your repayments are $2,500 a month, extinguishing the loan reduces your required annual income by $30,000. That means drawing less from your remaining super each year, which means the balance lasts longer, which compounds over a retirement that may run thirty years.
There is a risk dimension too. A retiree carrying fixed repayments is forced to draw a set amount from their pension account regardless of what markets have done. Drawing that amount after a sharp fall crystallises losses at the worst time, which is the sequencing risk that does the most damage in the early years of retirement. Removing the fixed obligation removes some of that pressure.
The estate consideration
Here is a point rarely made, and it can be worth a great deal to families with adult children.
The taxable component of superannuation paid to an adult child on death attracts tax, because adult children are generally not dependants for tax purposes. The family home passes through the estate under different rules entirely.
Converting assessable, eventually-taxable super into home equity therefore tends to improve the after-tax position of adult beneficiaries, not just your own pension entitlement. For someone weighing a paydown who also wants to leave something behind, that is a second argument pointing the same way.
It cuts differently if your beneficiary is your spouse, since a spouse receives super death benefits tax free.
The case against
None of the above makes this automatic. There are real reasons to hesitate.
It is close to a one-way door. Once the money is in the house, extracting it requires selling, downsizing, or a reverse mortgage. None of those is quick, and all carry costs.
You cannot simply put it back. Contribution caps limit what can go into super, the rules tighten with age, and after 75 most voluntary contributions are not permitted. Money withdrawn from super at 66 may not be replaceable at 72.
You lose the tax-free earnings environment. Inside a retirement phase pension, investment earnings are untaxed. That is a genuinely valuable place for money to sit, and every dollar withdrawn leaves it.
Liquidity matters more than people expect. Aged care costs, health expenses, home modifications, a car replacement and helping family all arrive in lump sums. A retiree with a paid-off house and very little accessible money is asset rich and cash poor, which is a stressful way to live.
Timing risk. Withdrawing a large sum shortly after a market fall converts a paper loss into a permanent one. If the plan is to clear the mortgage, the timing of that withdrawal deserves thought rather than being executed on the day you retire.
The middle grounds
The decision is rarely all or nothing, and the partial options are often better than either extreme.
Pay down to a target rather than to zero. Where the goal is to enter or optimise your position in the taper zone, the right paydown is a calculated figure, not the full balance. This is the single most valuable piece of modelling an adviser does on this question.
Keep a deliberate cash buffer. Clearing the loan while retaining two to three years of living expenses in accessible form addresses the liquidity objection without giving up the pension benefit.
Reduce and refinance rather than clear. Cutting the balance and extending the term lowers the repayment without exhausting your super, which suits people who want breathing room rather than a clean slate.
Consider the downsizer contribution instead. If selling the home is on the table, downsizer contributions allow eligible people aged 55 and over to contribute up to $300,000 each, or $600,000 per couple, from the proceeds. That runs in the opposite direction, moving money into super rather than out, and it suits different households. If you are weighing whether to keep the home at all, our article on renting versus owning in retirement works through that comparison.
The Home Equity Access Scheme. The government’s own reverse mortgage lets eligible older Australians draw against home equity at a rate generally below commercial equivalents. It is not a solution to a mortgage, but it is worth knowing about as a later-life liquidity option if you do put most of your money into the house.
Traps worth avoiding
Assuming tax free means free. The withdrawal costs no tax. It costs you the tax-free earnings environment, the liquidity, and the ability to put the money back.
Ignoring the income test. Reducing super also reduces deemed income, which can help under the income test as well. But the two tests interact, and whichever produces the lower payment applies. Modelling only one of them gives an unreliable answer.
Forgetting the partner’s position. Where one member of a couple is under Age Pension age, their accumulation super is generally not assessed while it stays in accumulation and is not paying an income stream. That timing can materially change when a paydown makes sense.
Doing it on the day you retire. There is rarely a reason to rush. The thresholds, your income needs and your market position are all worth assessing before a large irreversible withdrawal.
Treating an online calculator as advice. Assets test calculators handle the arithmetic. They do not handle the interaction between the two tests, your partner’s age, your liquidity needs, your beneficiaries and your time horizon.
A way to think it through
Work out your assessable assets first, then find where you sit relative to the current thresholds. That single fact determines whether the 7.8% argument applies to you at all, and it is the step most people skip.
Then ask what your income needs look like with and without the repayment, how much accessible money you want to keep, and what you want to happen to whatever is left.
If you land inside the taper zone, model the specific paydown amount rather than defaulting to clearing the loan entirely. If you land well above or well below it, the decision comes back to interest rates, liquidity and how you want to feel about the debt, which are legitimate considerations in their own right.
Getting it modelled
This is one of the highest-value pieces of advice available to Australians approaching retirement, because the sums involved are large, the transaction is difficult to reverse, and the correct answer varies enormously between two households that look similar from the outside.

Frequently asked questions
Can I use my super to pay off my mortgage?
Yes, once you meet a condition of release. Preservation age is 60, so from 60 you can access super if you have genuinely retired or ceased an employment arrangement, and from 65 you have full access regardless of your work status. For most Australians over 60 drawing from a taxed source, the withdrawal itself is tax free.
Does paying off my mortgage increase my Age Pension?
It can, significantly. The family home is exempt from the assets test while superannuation is assessable, so moving money from super into the home reduces your assessable assets. If you sit between the full-pension threshold and the cut-off, the pension reduces by $3 per fortnight for every $1,000 above the threshold, which is $78 a year, an effective 7.8%. Removing $100,000 from assessable assets in that zone is worth roughly $7,800 a year in additional pension.
When does paying off the mortgage not help my pension?
If your assessable assets are already below the full-pension threshold, you are receiving the full pension and further reductions gain nothing. If your assets are well above the cut-off, currently $733,500 for a single homeowner and $1,102,500 for a couple as at 1 July 2026, clearing the mortgage will not create an entitlement unless it brings you under that cut-off.
Is it a mistake to use all my super on the mortgage?
It can be. Money moved into the home is difficult to access again, contribution caps limit what you can put back into super, and after 75 most voluntary contributions are not permitted. Retaining two to three years of living expenses in accessible form is a common approach that addresses liquidity without giving up the pension benefit.
Should I pay off the mortgage or keep the money in super?
It depends primarily on where your assessable assets sit relative to the Age Pension thresholds, not on the interest rate comparison that dominates most discussion of this question. Inside the taper zone, the pension effect usually outweighs everything else. Outside it, the decision comes back to the loan rate, the tax-free earnings you give up inside a pension account, and how much liquidity you want.
Does using super to clear the mortgage affect what my children inherit?
Often favourably. The taxable component of super paid to an adult child attracts tax, because adult children are generally not dependants for tax purposes, while the family home passes through the estate under different rules. Converting super into home equity can therefore improve the after-tax position of adult beneficiaries. This does not apply where your beneficiary is your spouse, who receives super death benefits tax free.
What about downsizing instead?
Downsizer contributions allow eligible people aged 55 and over to contribute up to $300,000 each, or $600,000 per couple, from the proceeds of selling a qualifying home. That moves money into super rather than out of it, and it suits different circumstances. Note that selling converts exempt home value into assessable assets, which can reduce your pension, so it needs modelling in the same way.
General advice warning. This article contains general information only and does not take into account your objectives, financial situation or needs. Using superannuation to repay a mortgage is a large and largely irreversible decision, and money withdrawn from super often cannot be recontributed. Age Pension thresholds change each 20 March and 20 September, and figures quoted are current from 1 July 2026. You should confirm current rates with Services Australia and seek personal financial advice before acting on any of it.
