Superannuation Strategies in Your 30s and 40s: What Most People Miss

“You could have saved around $500,000.”

I’ve had to say this more times than I’d like. Often it’s when a client sits across from me later in life, wishing they had extra money for their home loan or to help the kids into their first property.

The reality is that the choices made 10 or 20 years earlier have massive consequences today.

The conversation about money usually focuses on what to invest in, property versus shares. But the bigger question is often how you invest, and what structure you use.

Superannuation: More Than Just an Investment

Many people think of superannuation as just another investment. They glance at their statement once a year to see if the balance has gone up or down.

But super isn’t an investment. It’s a tax structure, and it’s one of the most generous ones in Australia.

For higher-income earners, this makes a huge difference. Take someone earning above $190,000. Every extra dollar they earn is taxed at 49%. Put that same dollar into super and the tax rate drops to 15% (or 30% if you’re above $250,000).

That’s a 34% saving on tax.

Over time, the investment earnings inside super are also taxed at that concessional rate, and when you retire, you can even move a lot of it into a tax-free pension account. That could mean sidestepping capital gains tax entirely, potentially saving hundreds of thousands of dollars.

Why Not Put Everything Into Super?

This is where it gets personal.

Super comes with a big trade-off: once it’s in, you can’t touch it until you hit retirement age. That lack of flexibility can be a problem if life changes suddenly, like job loss, illness, or even the chance to buy a dream family home.

That’s why I always remind clients: before you add more to super, you need a buffer. Think about your cash flow, emergency savings and short-term plans. Only then should you decide how much you can afford to lock away.

The Classic Dilemma: Super vs Home Loan

If you’ve got spare cash, a common question is whether to pay off the home loan or top up super. Both can be smart moves. The right option depends on your goals, tax rate and need for flexibility.

Paying down the loan is straightforward. Extra repayments give you a risk-free return equal to your interest rate. If your home loan is 6.5% and you put in $1,000, you save $65 in interest every year. Simple and guaranteed.

Putting money into super is trickier but often more powerful. That same $1,000, if salary-sacrificed, becomes $1,960 gross. After the 15% contributions tax, you’ve got $1,666 invested. If it earns 8.6% (the 10-year average for a balanced option), you make $143. After tax, that’s $121.

That’s an after-tax return of around 12.1%. A lot stronger than 6.5%.

But Remember, Returns Depend on You

Superannuation returns aren’t one-size-fits-all. They depend on the option you choose, your tolerance for risk, and whether you stick with it when markets move around.

For example, the high-growth option in AustralianSuper has delivered 9.62% over 10 years. But it’s been bumpier than the balanced option. If you panic and switch out during a downturn, your personal return may be much worse than the headline number.

This is why super strategies in your 30s and 40s need to reflect your personal circumstances. For some, maximising tax savings makes sense. For others, reducing debt and keeping flexibility matters more. The best plan usually blends both.

Superannuation is not just a retirement fund, it’s a tax strategy. Done right, it can supercharge your long-term wealth. But locking money away comes with trade-offs.

For ambitious families in their 30s and 40s, the real win is finding the balance. Make sure you’ve got flexibility for the short-term, while also using the power of super for the long-term.

That balance is different for everyone. Which is why the smartest strategy isn’t just about chasing returns, it’s about matching money decisions to your life today and your goals for tomorrow.
