Super or ETFs First? How to Decide When to Stop Topping Up Super
Super gives you the best tax deal in Australia, but you can't touch it until 60. Here is a simple way to decide how much goes into super and how much into ETFs.

It is one of the most common questions in Australian FIRE circles: "Should my extra savings go into super or into ETFs?" Both are good homes for long-term money. Super has the better tax deal. ETFs have the better access. The right answer for you depends mostly on one thing: when you want to stop working.
This guide walks through the trade-off, shows the tax maths, and gives you a simple way to decide how to split your savings between the two.
Why this question matters
Every dollar you invest for the long term has to live somewhere. For most Australians, that means one of two buckets:
- Super, your superannuation fund. Contributions and earnings are taxed lightly, but the money is locked away until you reach your preservation age (60 for anyone born after 30 June 1964) and meet a condition of release, such as retiring.
- Outside super, usually a brokerage account holding ASX-listed ETFs such as VGS, VAS, VDHG or DHHF. Earnings are taxed at your normal marginal rate, but you can sell and spend the money any time.
If you plan to work until 65, putting more into super is usually a straightforward win. If you want to retire at 45, money locked in super until 60 can't pay your rent for fifteen years. That gap is the heart of the question.
The case for super: tax
Your employer already pays the Super Guarantee (12% of your ordinary earnings) into super. You can add more yourself, most commonly through salary sacrifice, where part of your pre-tax pay goes straight into super.
Salary-sacrificed contributions are called concessional contributions. They are taxed at 15% going in instead of your marginal rate. For the 2026–27 financial year, the concessional cap is $32,500 a year, and that includes your employer's Super Guarantee payments. If your income is above $250,000, an extra 15% (called Division 293 tax) applies, so the benefit shrinks.
Here is what that looks like for someone on a 32% marginal rate (30% plus the 2% Medicare levy) choosing where $10,000 of pre-tax salary goes.
Tax = $10,000 × 32%
Tax = $3,200
Invested in ETFs = $6,800
# Option B: salary sacrifice into super
Tax = $10,000 × 15%
Tax = $1,500
Invested in super = $8,500
Super starts you off with $1,700 more invested, a 25% head start. And it keeps going. Earnings inside super are taxed at up to 15% while you are working, and generally 0% once you move the money into the retirement phase (up to the transfer balance cap, which is $2.1 million from 1 July 2026). Outside super, dividends are taxed at your marginal rate every year.
The gap is also widening. From 1 July 2027 the 50% capital gains tax discount for investments held outside super is being replaced by cost base indexation and a 30% minimum tax on capital gains. Our guide to the 2026 Budget CGT changes runs the numbers. In short: future gains outside super will be taxed a little more heavily than they are today.
The case for ETFs: access and flexibility
Tax isn't everything. Money outside super has advantages super can't match:
- You can spend it before 60. This is the big one for early retirees.
- Rules can't lock it up further. Super rules, caps and taxes change regularly. Money outside super is yours to use on your own terms.
- It works for life events. A house deposit, a career break, starting a business or helping family are all things super can't fund.
- It gives you options. Even if you never retire early, having the choice to step back from work at 50 has real value.
Our guide to the ultimate guide to ETFs covers how ETFs work if you are just getting started.
The real constraint: bridging to 60
For an early retiree, the question isn't really "super or ETFs". It's "how much do I need in each bucket so that both stages of retirement are covered?"
Think of retirement in two stages:
- The bridge: from the day you stop work until 60. Only money outside super can pay for this.
- Super age: from 60 onwards. Super takes over, and any ETFs left over are a bonus.
A rough way to size each bucket, in today's dollars:
Bridge amount ≈
Annual spending × Years until 60
# Stage 2: super at 60
Super target ≈
Annual spending × 25
The "× 25" comes from the 4% rule, which we explain in FIRE 101. The bridge formula is deliberately conservative: it assumes you spend the bridge money down to zero and ignores the growth it earns along the way. If you want a tighter number, you can use a 4% to 5% withdrawal rate on the bridge instead.
A worked example
Say you spend $60,000 a year and want to retire at 45.
Bridge ≈ $60,000 × 15
Bridge ≈ $900,000
# Super at 60
Super target ≈ $60,000 × 25
Super target ≈ $1,500,000
Now look at what you already have. If you're 30 with $80,000 in super and your employer keeps contributing 12%, compound growth may get that close to the super target on its own by 60. In that case, extra salary sacrifice adds little, and nearly all of your extra savings should go into ETFs to build the bridge.
If you're 45 with a small super balance and no plan to stop working early, the opposite is true. Super's tax advantage wins, and topping it up makes sense.
A simple way to decide the split
Here is a practical order of operations most people can follow:
- Get the basics sorted. An emergency fund, no high-interest debt, and your employer's Super Guarantee going into a low-fee, diversified option.
- Estimate your two targets. Use the formulas above for your bridge and your super target.
- Project your super. Most super funds have a calculator. Check whether your current balance plus employer contributions is on track to reach the super target by 60.
- If super is on track, prioritise ETFs. Put extra savings outside super to build the bridge.
- If super is behind, salary sacrifice the gap. Contribute enough to get back on track, staying under the $32,500 concessional cap.
- Revisit every year or two. Pay rises, market returns and life changes all shift the numbers.
| Your situation | Lean towards |
|---|---|
| Retiring at 60 or later | Super, up to the concessional cap |
| Retiring early, super already on track | ETFs, to build the bridge |
| Retiring early, super behind | A mix: enough super to get on track, the rest ETFs |
| Income above $250,000 | Still often super, but the gap is smaller |
| Need the money for a house or a big goal | ETFs, or the First Home Super Saver scheme |
| Very low income | Check the government co-contribution before choosing |
Common mistakes to avoid
- Ignoring super because it feels far away. It is still the most tax-effective investment most Australians have. Don't stop employer contributions or choose a high-fee option.
- Overfilling super and starving the bridge. If you want to retire at 45, a large super balance and no ETFs means working until 60 anyway.
- Going over the cap. Remember the $32,500 concessional cap includes your employer's contributions. Check your total before adding more.
- Forgetting carry-forward contributions. If your super balance is under $500,000, you can use unused concessional cap amounts from the previous five years. This can help in a high-income year.
- Choosing a different strategy in each bucket. The investments inside super and outside it should work together. Our model portfolios guide is a good starting point for the outside-super side.
Conclusion
Super and ETFs aren't rivals. They're two tools for two stages of life. Super wins on tax, and ETFs win on access. For anyone planning to work until 60 or beyond, super deserves most of your extra savings. For anyone planning to retire early, the goal is to get super on track, then build your outside-super bridge as fast as you can.
Your next step: work out your annual spending, pick a target retirement age, and run the two formulas above. Then log in to your super fund's calculator and see whether your balance is on track. That one hour of maths will tell you where your next dollar should go.
