Should You Put Your Extra Money Into Your Super or Your Mortgage?

For many Perth homeowners, the question of what to do with surplus income often boils down to a fundamental financial dilemma: should you put your extra money into your super or your mortgage? Both paths offer significant long-term financial benefits, but they serve different purposes and come with distinct trade-offs. Making the right choice is not a matter of a one-size-fits-all answer; rather, it is a deeply personal decision that hinges on individual circumstances, including age, income, debt level, and retirement goals.

At Approved Financial Planning, we understand the complexity of this decision. Our role is to provide clear, unbiased guidance, helping you weigh the pros and cons of each strategy against your unique financial landscape. We are well-positioned to discuss both sides of this critical choice, ensuring your decision aligns perfectly with your long-term wealth creation and retirement objectives.

The Case for Superannuation: A Tax-Advantaged Powerhouse

Superannuation, Australia’s compulsory retirement savings system, is often described as the most tax-effective investment vehicle available. For homeowners looking to maximise their retirement nest egg, extra contributions to super can be a powerful strategy.

Pros of Contributing Extra to Super

Benefit	Description	Key Advantage
Significant Tax Concessions	Concessional contributions (e.g., salary sacrifice or personal contributions claimed as a tax deduction) are generally taxed at a flat rate of 15% 1. For most Australians, this is substantially lower than their marginal income tax rate, which can be as high as 45% (plus the Medicare levy). This immediate tax saving is a major drawcard.	Immediate Tax Savings: Reduces current taxable income, putting more money to work.
Compounding Returns	Super funds invest in a diversified portfolio of assets. Over the long term, these investments benefit from compounding growth. The median growth super fund has historically delivered strong returns, with the median growth fund returning approximately 10.5% in the financial year ending June 2025 2.	Accelerated Wealth Growth: Higher potential returns than the guaranteed "return" of paying down a mortgage (which is equal to the interest rate saved).
Tax-Free Retirement Income	Once you reach age 60 and meet a condition of release (like retirement), all withdrawals from your super are generally tax-free 3. This is a massive advantage over drawing down on non-super investments.	Ultimate Tax Efficiency: Zero tax on income and capital gains in retirement.
Protection from Creditors	In most circumstances, superannuation assets are protected from creditors, offering a layer of financial security that other personal assets may not have.	Asset Protection: Safeguards retirement savings against financial distress.

Cons of Contributing Extra to Super

Drawback	Description	Implication for Homeowners
Access Restrictions (Preservation Age)	Superannuation is a long-term savings vehicle. Funds are generally "preserved" until you reach your preservation age (currently between 55 and 60, depending on your date of birth) and meet a condition of release 4.	Illiquidity: Money is locked away and cannot be used for emergencies or other investments until retirement.
Contribution Caps	The government imposes strict annual limits on how much you can contribute. The concessional contributions cap (before-tax) is currently $30,000 per financial year (FY25/26) 5. Exceeding these caps can result in additional tax penalties.	Limited Flexibility: You cannot simply inject a large, one-off windfall without careful planning.
Division 293 Tax	High-income earners (those with income and concessional contributions over $250,000) pay an additional 15% tax on some or all of their concessional contributions, effectively taxing them at 30% 6.	Reduced Tax Advantage: The benefit is lessened for very high earners.

The Case for Mortgage Paydown: Guaranteed Return and Financial Freedom

For many Perth homeowners, the mortgage is their largest and most significant debt. Aggressively paying it down offers a tangible, risk-free return that can provide immense peace of mind and financial flexibility.

Pros of Paying Down Your Mortgage

Benefit	Description	Key Advantage
Guaranteed, Risk-Free Return	Every dollar you pay off your mortgage is a dollar you don't pay interest on. This "return" is guaranteed and is equivalent to your home loan interest rate. With average variable interest rates for owner-occupiers currently around 6.44% p.a. 7, this is a substantial, risk-free saving.	Certainty: A guaranteed return that is not subject to market volatility.
Reduced Interest Costs	By making extra repayments, you reduce the principal amount faster, which means less interest is charged over the life of the loan. This can shave years off your mortgage term and save tens of thousands of dollars in interest.	Accelerated Debt Reduction: Builds equity faster and achieves debt-free status sooner.
Increased Financial Flexibility (Offset/Redraw)	Most Australian home loans offer an offset account or a redraw facility. Extra funds placed in an offset account are held in a separate transaction account and reduce the interest charged on the loan balance daily, while remaining fully accessible 8. A redraw facility allows you to withdraw extra payments you've made, offering a readily available emergency fund 9.	Liquidity and Safety Net: Provides a highly liquid, tax-free emergency fund.
Psychological Benefit	The feeling of reducing a large debt and moving closer to outright home ownership is a powerful motivator. This "sleep-at-night factor" is an intangible but valuable benefit.	Peace of Mind: Reduces financial stress and improves overall well-being.

Cons of Paying Down Your Mortgage

Drawback	Description	Implication for Homeowners
No Tax Deduction	Unlike super contributions, extra mortgage repayments are made with after-tax dollars and offer no immediate tax deduction.	Less Tax Efficient: You miss out on the immediate tax saving offered by concessional super contributions.
Lower Potential Return	While the return is guaranteed (equal to the interest rate), it is often lower than the long-term, tax-advantaged returns generated by a well-performing super fund. If your super fund is consistently returning 8-10% and your mortgage rate is 6.44%, you are missing out on potential growth.	Opportunity Cost: Sacrifices potentially higher market returns for a guaranteed, lower return.
Illiquidity (Redraw vs. Offset)	While offset accounts offer excellent liquidity, funds paid into a redraw facility are technically a reduction of the loan principal. If the bank fails or the loan terms change, accessing these funds can sometimes be more complex than accessing an offset account.	Varying Liquidity: Depends on the specific loan feature (offset is superior for liquidity).

The Approved Financial Planning Framework: Which Path is Right for You?

The optimal strategy is rarely a simple choice between one or the other. Instead, it involves a balanced approach tailored to your specific life stage and financial metrics. Approved Financial Planning uses a structured framework to guide Perth homeowners through this decision.

1. The Foundation: Debt and Liquidity

Before considering super, we always recommend establishing a solid financial foundation.

•Emergency Fund: Ensure you have at least three to six months of living expenses readily accessible. An offset account is the ideal place for this, as it reduces your mortgage interest while keeping the funds liquid and tax-free.

•High-Interest Debt: Pay off all high-interest consumer debt (credit cards, personal loans) before tackling the mortgage or super. The interest rate on these debts will almost certainly exceed both your mortgage rate and your expected super returns.

2. The Tipping Point: Comparing Rates

The decision often comes down to a simple comparison of rates:

For most people, the tax advantage of superannuation (15% tax on contributions) means that even a moderate super return can outperform the guaranteed saving from the mortgage interest rate. However, if you are a high-income earner subject to Division 293 tax, or if your super fund is underperforming, the guaranteed return of paying down a mortgage becomes more compelling.

3. The Life Stage Factor

Your age and proximity to retirement are the most critical factors in this equation.

Life Stage	Recommended Focus	Rationale
Early Career (20s-30s)	Superannuation & Mortgage Offset	Maximise the power of compounding growth in super. Use an offset account to build an emergency fund and maintain liquidity for future life events (e.g., children, career change).
Mid-Career (40s-50s)	Balanced Approach (Super to Cap & Mortgage Paydown)	Prioritise contributing to super up to the concessional cap to maximise tax benefits. Simultaneously increase mortgage repayments to ensure the home is paid off before retirement.
Pre-Retirement (Late 50s-60s)	Mortgage Paydown & Non-Concessional Super	Focus on eliminating the mortgage entirely to reduce fixed expenses in retirement. Use non-concessional (after-tax) super contributions if you have unused caps, as withdrawals are tax-free after age 60.

4. The Perth Property Context

As Perth house prices continue to climb, with the median sale price for houses in Greater Perth reaching approximately $820,000 in October 2025 10, building equity is a key goal. Aggressive mortgage paydown directly increases your equity, which can be crucial if you plan to use that equity for future investments or property upgrades within the Perth market.

Conclusion: Your Super or Your Mortgage

The choice between paying down your mortgage and contributing extra to superannuation is a classic financial planning puzzle. It pits the guaranteed, risk-free return and liquidity of mortgage reduction against the tax-advantaged, higher-growth potential of superannuation.

There is no single correct answer, but there is a best answer for you.

We will analyse your current tax position, assess your risk tolerance, project your long-term super returns, and model the impact of accelerated mortgage payments to determine the optimal allocation of your surplus funds.

I started seeking financial advice about 10 years ago. Been through a couple of companies in that time, and AFP is the latest iteration. The previous companies were not bad, but they morphed or changed & like anyone I want a little stability. AFP have given me that stability, even if individual advisors have moved on! Tracey is my latest advisor & I could not be more comfortable. She's thorough, professional, quick with a personal anecdote to emphasise a point & not condescending about my lack of financial knowledge. Now that my retirement is looming she is taking care of all the paperwork & intricacies that go with switching to a new income stream.
What more could you ask for???

My meeting with Daniel was very positive as we discussed a range of issues in relation to my superannuation and my financial and personal health which were pertinent to me. Also looked at what if cash flow scenarios in regard to bookkeeping opportunities and creating a new super fund if matters come to pass. Also the coffee and biscuits were great.

Thanks Dan and Staff for the annual review. The forecasting for retirement and the software used was very illustrative and useful to understand. Growth in funds and super has been robust in the last 12 months and advice for the next 12 months taken on board. Look fwd to making a few tweaks to the portfolio once the report is completed.
