UniSuper Balanced: $38,687 ahead of retail funds over 15 years 🇦🇺

▶

A 30-year-old Australian worker on an average balance can lose tens of thousands of dollars by staying in a weaker super option instead of a better-performing one, even before you add insurance differences or extra fees.

The number that matters

UniSuper’s Balanced option was shown as $21,688 better off over 15 years than the industry median and $38,687 better off than the retail master trust median, based on net outcomes to 31 December 2025.

How it quietly costs you

The first quiet cost is net underperformance: fees matter, but the bigger drag is often a fund or option that compounds at a lower net return over decades.

UniSuper’s own comparison tool defines the key metric as net benefit — investment returns minus fees and costs — and says to compare similar investment options over 5 to 10 years, because short-term snapshots can mislead. In its example, UniSuper’s Balanced option delivered a 15-year net outcome of $180,635, which was $21,688 better than the industry median and $38,687 better than the retail master trust median.

Old vs better: the “old” approach is picking a fund by brand or default alone; the better approach is comparing the same style of option on long-term net outcomes, not just headline fees.

The second, compounding trap

The second layer is fee drag inside the account, especially administration and investment fees that are charged every year and compound against the balance.

Rest’s comparison guide warns that if fees are too high, they can eat into your super balance over time, and recommends comparing net return rather than fees in isolation. The ATO’s YourSuper tool exists because people need a simple way to compare funds on performance, which reflects the policy concern that even small annual differences compound into large retirement differences over time.

A practical way to frame the long-run cost is this: if a member stays in a weaker option that compounds below a comparable option by even a modest amount, the gap can widen to five figures over 15 years and far more over a full working life.

What this looks like in practice

Mia, 34, hospital nurse, $82,000 salary, $64,000 in HESTA default Balanced, 31 years to retirement. She is comparing HESTA, Cbus, UniSuper, and REST because her role is covered by HESTA, but she has heard that other industry funds may have better returns or lower fees.

She would likely discover:

• Discovery 1: On UniSuper’s own comparison example, the 15-year net outcome gap versus the industry median is $21,688 and versus the retail master trust median is $38,687. That is the difference between a fund that compounds better and one that does not.

• Discovery 2: The ATO’s YourSuper tool is designed to compare funds on performance, which matters because a seemingly small annual edge becomes a large retirement-dollar difference over decades. In other words, doing nothing can be much more expensive than switching after checking the numbers.

• Discovery 3: Rest’s guide says to compare net return, not just fees, because fees alone do not tell you which fund leaves you with more money at retirement. That means a “cheap” fund with weaker returns can still leave you worse off than a slightly more expensive fund with better investment performance.

The full cost of doing nothing

For Mia, the combined effect of weaker performance plus fee drag can plausibly reach $20K–$40K+ over 15 years if she remains in a materially inferior option, using UniSuper’s published example as the benchmark for a comparable balanced portfolio.

That figure is a modelling guide, not a guarantee: the exact outcome depends on contribution rate, balance, insurance costs, and which investment option she chooses across HESTA, Cbus, UniSuper, or REST.

What to do about it

• Compare the fund options in the ATO YourSuper comparison tool and check the personalised or non-personalised result for performance, then identify which MySuper product is on top for your situation.

1. Open YourSuper comparison tool.
2. Enter your details or use the non-personalised view.
3. Compare the MySuper option, fees, and returns. Good looks like: your current fund is competitive on long-term performance and not materially behind the better MySuper options.

• Check HESTA’s RateMySuper comparison tool to benchmark HESTA against other funds on performance, fees, insurance, member services, administration, and governance.

1. Open RateMySuper.
2. Select HESTA and compare it with peers.
3. Review fee and performance differences on a like-for-like basis. Good looks like: HESTA’s relevant option is competitive on both returns and fees versus the peer set.

• Use UniSuper’s Compare super funds tool to compare “apples with apples” on similar investment options and net outcomes, then match the option style to your risk profile.

1. Open the comparison tool.
2. Select similar investment options across funds.
3. Compare 5-, 10-, and 15-year net outcomes. Good looks like: the option you hold sits near the top on long-term net outcome for the same risk bucket.

A myth worth clearing up

Myth: The lowest-fee fund is always the best choice. Fact: The better comparison is net outcome — returns after fees and costs — because a slightly higher-fee fund can still leave you with more money if its investment performance is stronger.
