It’s one of the most common questions we hear.
When you’ve got a bit of extra money to work with, deciding whether to direct it into your mortgage or top up your super can feel like a tough financial question. Both options are sensible. Both offer long-term benefits. But the right choice depends on a few key factors.
Let’s unpack the considerations.
The case for paying down your mortgage
For many Australians, the mortgage is the single largest debt they’ll carry in their lifetime. Paying it off faster can:
- Save significant interest over time
- Build equity in your home
- Reduce financial stress
- Improve flexibility for future borrowing or downsizing
In a higher-rate environment, the interest savings alone can be compelling. Extra repayments provide a guaranteed return – equivalent to your mortgage rate but without the investment risk.
There’s also a psychological benefit to owning your home outright. For those approaching retirement, the prospect of being debt-free can bring real peace of mind.
The case for investing in super
On the other hand, contributing more to super can offer a powerful combination of tax savings and long-term compounding.
Salary sacrificing or making personal concessional contributions (up to the $30,000 cap for 2025–26) allows you to invest pre-tax dollars into super, typically taxed at just 15%. For high-income earners, this can be significantly lower than your marginal tax rate.
Over time, even modest additional contributions can grow meaningfully particularly if you have time on your side and a well-structured investment strategy in place.
Super also enjoys tax-friendly treatment in retirement, with investment earnings and withdrawals often tax-free once you’re in the pension phase.
A few questions to ask yourself
Rather than viewing this as an either/or decision, we encourage clients to consider the bigger picture.
How many years until you plan to retire? If you’re 10 or more years out, your super has time to grow and benefit from compound returns. If you’re closer to retirement, clearing your mortgage might provide more immediate benefits and improve your cash flow once you stop working.
What’s your marginal tax rate? The higher your income, the more value you may get from salary sacrificing or making deductible super contributions. The tax savings can amplify the long-term benefit.
How comfortable are you with investment risk? Super is invested, so it comes with market volatility. If you’re conservative or nearing retirement, you may prefer the certainty of a guaranteed return by reducing your home loan.
Do you have access to the funds if needed? Super is preserved until you meet a condition of release, usually retirement. Extra mortgage repayments, especially into an offset account or redraw facility, may offer more flexibility in the short term.
Are you nearing key thresholds? If your total super balance is approaching $3 million, the proposed Division 296 changes could impact your strategy. Similarly, those nearing retirement should be conscious of how contributions interact with transfer balance caps and pension planning.
A blended strategy often works best
For many of our clients, the smartest approach isn’t all or nothing, it’s a bit of both.
You might use salary sacrifice to make tax-effective super contributions up to your cap, while also directing surplus cash or bonuses to reduce your mortgage. Or prioritise mortgage repayments now, knowing you’ll have room to catch up on super contributions in the coming years, particularly using catch-up concessional rules if eligible.
It’s not just about maximising returns. It’s about managing risk, creating flexibility and making sure your financial decisions support the life you want now and in the future.
Final word: tailor the plan to you
Financial advice isn’t about choosing between two good options. It’s about structuring your decisions in a way that aligns with your goals, timeframe and values.
At Empire, we help clients take a step back and look at the whole picture. Whether you’re five years out from retirement or still building your wealth, we’ll guide you through.
