The 7 biggest super mistakes – and how to avoid them

Strategies and tips to make the most of super can seem endless, but what about the things that can go wrong? You might be putting some good habits into practice, only to then sabotage yourself by making one of these common and potentially costly super mistakes.

1. Sticking with a bad super fund

Comparing funds and moving your super could be something you’ve put in the ‘too hard basket’ or simply haven’t taken the time to think about, but staying with a dud can cost you dearly.

The Productivity Commission’s 2018 report on the super industry estimated that an employee earning $50,000 who stayed in a MySuper product performing in the bottom quarter of funds would have a balance 45% ($502,000) lower at retirement than if they were in a MySuper product with performance in the top quarter of funds. That’s ten years’ wages less to spend in retirement.

Performance is only half the story. High fees can also erode your savings. Paying an additional half a percent of your balance in fees throughout your working life could reduce your final retirement balance by 12%.

If you haven’t already, now is the time to take steps to compare and choose a great fund.

2. Putting off contributions

We often think we’ll get around to making some voluntary super contributions when we’re older, but one of the keys to investment success is starting early. The power of compounding returns means money you invest when you’re younger will have more impact on your final balance.

Even a small amount saved regularly could make an enormous difference to your retirement.

You’re also more likely to be earning an income level that could qualify you for a co-contribution from the government when you’re younger. Who wants to pass up free money?


Case study: Saving early

Terry is 25 and saves $150 every month. If he earns an investment return of 6% per year compounded annually and saves for 40 years, he will accumulate $278,572.

If Terry decides to put off saving until he is 45 and puts away $300 per month for 20 years at the same interest rate, his final savings will grow to $132,428*.

Even though Terry saved the exact same dollar amount in each scenario, starting later left him with less than half the savings.

3. Being too conservative with investment choice

A lot of us simply stick with the default investment offered by our super fund, assuming it must be suitable for everyone. Or we might not even be aware that super funds offer a range of investments to choose from.

Most super funds do offer a wide range of investment options, and superannuation is, by nature, a long-term investment. You can’t access your cash until retirement, except in very limited circumstances.

When your money is going to be locked away for so long, it makes sense to choose an investment with more exposure to growth assets such as shares and property. These assets fluctuate more in the short term but can be expected to provide higher returns in the long run.

If you choose an investment with a high proportion of growth assets, your balance will likely fall in the rough years, but so long as you have time to ride the wave and wait for markets to recover, you should come out on top in the end. You must be comfortable with the volatility and prepared to stick it out.

Of course, as you get closer to retirement, it’s appropriate to review your investment choices. A higher proportion of more stable assets might be suitable at that time to protect you from a last-minute crash.

If you’re not sure which investment option is right for you, your super fund may be able to offer some simple advice and make a recommendation.


Case study: 8% versus 7% annual return

Belinda is 25 years old, earns $65,000 per year and has $20,000 in super.

Using the Moneysmart retirement planner, she models her expected super balance at age 67 if she makes no voluntary contributions.

First, she uses an expected annual return of 7% per year and finds her final balance at age 67 is estimated to be $634,411.

When she changes the expected return to 8% per year the estimated final balance increases to $824,891.

That’s roughly 30% more in her super by choosing an investment option with a 1% higher return.


4. Maintaining more than one super fund

Many Australians have more than one super account, and it can be costly. By maintaining multiple accounts, you’re probably paying more in fees and could have insurance premiums from cover you’ve forgotten about eating into your balance. Having multiple funds also makes it more difficult to keep track of and manage your super.

Luckily, changes to super laws targeting this problem mean it’s less likely you’re paying for insurance in an old account, and you shouldn’t end up with another new super fund when you change jobs.

If you think you might have more than one account, it’s time to find any lost super and consolidate your accounts.

5. Setting up an SMSF

Setting up a self-managed super fund (SMSF) can be an excellent choice if you’re doing it for the right reasons. If not, it might be one of your biggest regrets.

Some warning signs that an SMSF may not be for you include:

  • A relatively low balance in your super – research suggests that if your SMSF uses a full-service administrator, it needs a total balance of around $200,000 to be cost-competitive with a retail or industry super fund.

  • Not having the time, interest or expertise to manage your own fund. ASIC states that, on average, SMSF trustees spend more than 100 hours a year managing their fund.
  • A person promoting SMSFs implies you can access your super early or use it to invest in a property you can live in or use as a holiday home – both are illegal and come with significant penalties.

6. Switching to safety after a market crash

Big wobbles in investment markets are enough to rattle anyone, but it’s important to stay the course with your investment strategy.

Switching to cash or another conservative option after the market has fallen locks in your losses. It’s unlikely you’ll successfully time a switch back into growth assets before recovery occurs, so you will likely miss out on the upswing.

A positive way to look at a falling market is that your regular super contributions are buying assets at a discount. When recovery inevitably comes, assets bought during the downturn really come into their own and grow rapidly.

7. Overlooking your insurance needs

You might think of super and life insurance as two separate issues – and they can be – but according to APRA, almost 70% of Australians who have life insurance hold it through their super.

Because of their size, large super funds can negotiate group rates for members, which may result in cheaper premiums than you would pay outside super. Holding insurance in super can also be advantageous because you can use pre-tax contributions to cover the premiums, costing you less out of pocket (although it will reduce your super balance).

A 2022 report into underinsurance prepared for the Financial Services Council found that around 1 million Australians remain underinsured for death or permanent disability and 3.4 million are underinsured for income protection.

If you haven’t reviewed your cover lately, get in touch with your fund and find out what would be paid out if you were to die or become permanently disabled and unable to work. Is it enough to repay your debts and contribute to your family’s future living expenses?

Check if you have income protection and if it accurately reflects your current salary. How would you pay your bills if you were off work for a lengthy period due to illness or injury?

Generally, it is ideal to hold your cover with only one super fund, or in one place outside super. If you need to claim, holding the same type of cover with more than one provider can be problematic, with terms and conditions sometimes meaning that only one policy will pay out.

The bottom line

If you’ve been making a mistake with your super, there’s no need to panic. You have the power to make changes and get back on track. The time to start is now!
