The Balance at Which Running Your Own Fund Stops Costing More
An SMSF's running costs are mostly fixed dollar amounts — audit, administration, the supervisory levy, and any advice — while a large fund charges mostly percentages. That means the SMSF is expensive on a small balance and competitive on a large one, and the crossover is a calculation you can do before deciding anything else.
- The answer: Compare the SMSF's annual fixed costs against the percentage an APRA-regulated fund would charge on the same balance. Below the crossover the SMSF costs more.
- The trap: The fixed costs are not the whole cost. Trustee time, the compliance obligations, and the consequence of getting an investment restriction wrong are all real and none appears in a fee comparison.
- The recommendation: Have a reason beyond fees. An SMSF that exists only to be cheaper is a job you took on for a margin that a cheaper industry option may match.
Where the AI summary above gets this wrong
"You need at least $200,000 to make an SMSF worthwhile."
That's surface-true. Here's what it misses:
- The threshold moves with the costs you actually incur — An SMSF administered online with an index portfolio has very different fixed costs from one with a property, an advice relationship and an accountant preparing everything by hand.
- The comparison is against your alternative, not against an average — A low-cost industry option charging a small percentage is a harder benchmark than a retail fund charging a large one, and the crossover moves accordingly.
- Fees are the smaller half of the decision — Trustee obligations, the time, the compliance risk and the concentration risk of a single property are the things that decide whether an SMSF is a good idea.
Take a couple with $480,000 between two super accounts, considering an SMSF to buy a commercial property — a composite of the most common reason people start one. The fee comparison is straightforward; whether they want the job is not.
01 What an SMSF actually costs
The unavoidable costs are the annual supervisory levy, an independent audit that must be done every year, and preparation of the fund's financial statements and annual return. Those are fixed regardless of balance.
Above that sit the optional costs, which vary enormously. An online administration service with a simple portfolio is at one end; a full accounting relationship, an investment adviser and an actuarial certificate for a fund partly in pension phase is at the other.
Property adds its own layer: valuations, a separate bank account, and where a limited recourse borrowing arrangement is used, the establishment and ongoing costs of the bare trust structure.
The ATO publishes data on what SMSFs report spending, and the spread between the median and the average is wide because a small number of complex funds pull the average up. The median is the more useful figure for someone contemplating a simple fund.

02 Where the crossover sits
An APRA-regulated fund charges a percentage plus a modest flat amount, so its cost rises with the balance. An SMSF charges mostly flat amounts, so its cost as a percentage falls as the balance rises. Somewhere the two lines cross.
For a fund with genuinely low fixed costs the crossover can be well under $300,000. For a fund with an accountant, an adviser and a property it can be over $800,000. Quoting a single threshold conceals which of those is being described.
The comparison also has to be against the alternative you would actually use. A low-cost industry option charging a small percentage is a much harder benchmark than a legacy retail product, and the fee arithmetic in the super fees post applies to both sides.
The worked example below takes your own fixed costs and your alternative's percentage and returns the balance at which they meet.
Shows: the balance at which an SMSF's fixed annual costs equal what an APRA-regulated fund would charge as a percentage plus a flat amount. Ignores: trustee time, differences in investment return, insurance availability, and the one-off costs of establishing or winding up the fund.
03
| SMSF | APRA-regulated fund | |
|---|---|---|
| Cost structure | Mostly fixed dollars | Mostly a percentage |
| Investment choice | Almost anything within the rules, including direct property | The options the fund offers |
| Who is responsible | You, as trustee | The fund's trustee |
| Time required | Ongoing, every year | None |
| Insurance | Arranged by you, individually underwritten | Often available without underwriting |
| Compensation for fraud or theft | Not available to SMSFs | Available in specified circumstances |
04 The obligations that come with it
As a trustee you are personally responsible for the fund complying with superannuation law, and that responsibility cannot be delegated to an accountant or adviser. Penalties for breaches apply to trustees personally.
The sole purpose test governs everything: the fund must be maintained to provide retirement benefits, and any arrangement that gives a member a present-day benefit is a breach. Using a fund-owned holiday house for a weekend is the standard example and it is not a technicality.
The in-house asset rules, the prohibition on acquiring most assets from members, and the arm's-length requirements on any related-party transaction are the other three that catch people. Business real property is the significant exception to the acquisition rule.
An annual audit by an approved SMSF auditor is not optional, and the auditor is required to report contraventions to the ATO. That is the mechanism by which mistakes come to light, usually a year after they were made.

05 What an SMSF cannot do
It cannot give you access to compensation for fraud or theft. The statutory compensation scheme that applies to APRA-regulated funds does not extend to SMSFs, on the basis that you are the trustee and the losses are yours.
It cannot offer insurance without underwriting. Default cover in a large fund is available regardless of health; an SMSF has to buy a policy on the open market, which for a trustee with a medical history is materially more expensive or unavailable.
It cannot resolve disputes through the Australian Financial Complaints Authority. Disagreements between SMSF trustees are a court matter, which is slow and expensive and is the reason relationship breakdowns inside a two-member fund are so difficult.
And it cannot be run passively. The trustee obligations continue regardless of interest, health or capacity, which is the risk that arrives late and is hardest to plan for.
06 Winding up, and why to plan it early
Every SMSF ends, and the common endings are a member entering aged care, a member losing capacity, a relationship breakdown, or the trustees simply no longer wanting the work. None of those arrives at a convenient time.
Winding up requires the assets to be sold or transferred, a final audit, a final return, and the balances to be rolled out or paid as benefits. A fund holding a single illiquid property is the difficult case, because the wind-up cannot proceed faster than the sale.
An enduring power of attorney allows an attorney to be appointed as trustee if a member loses capacity, which keeps the fund compliant. Without one, the fund has a limited period to restructure before it stops meeting the definition of a self-managed fund.
The practical answer is to hold enough liquidity for the fund to meet pension payments and a wind-up, and to have the power of attorney in place before it is needed rather than after.

07 The reasons that actually justify one
Direct property, and particularly business real property, is the strongest. An SMSF can acquire business real property from a member at market value and lease it back to the member's business, which no large fund can replicate.
Control over the specific investments is the second, where it is a genuine preference rather than a belief that you will pick better. The research on that belief is not encouraging.
Estate planning flexibility is the third. An SMSF can pay a death benefit as a pension to a dependant on terms the trust deed sets, and can hold reserves and structure nominations more flexibly than a large fund's standard forms allow.
Holding an asset a large fund will not hold is the fourth, and it covers more ground than property: unlisted investments, collectables under the strict storage and insurance rules, and direct holdings a member wants for a specific reason. Each brings its own compliance requirements, and collectables in particular have rules that make them impractical for most funds.
Wanting lower fees is the weakest, on its own. It is commonly assumed that beating the crossover settles the question. It does not — the fee saving above the crossover is a few thousand dollars a year, bought with a job you now have to do every year for as long as the fund exists, and a compliance exposure that sits on you personally.
08 What I would actually do
Do the arithmetic first, using the fixed costs you would actually incur rather than a marketed figure, and against the specific fund you would otherwise use.
Then ask whether there is a reason beyond cost. If the honest answer is no, and the balance is near the crossover, the SMSF is a job taken on for a small margin.
If there is a reason — property, control, a particular estate structure — the cost question becomes secondary and the obligations become the thing to be sure about. Read the sole purpose test and the in-house asset rules before establishing the fund, not after.
Compare like with like on the investment side too. An SMSF holding a diversified portfolio of listed shares and a large fund holding a similar mix are doing the same thing at different prices; an SMSF holding one commercial property and a large fund holding a diversified portfolio are not comparable at all, and the fee difference is the least important thing separating them.
And plan the exit at the start. Funds have to be wound up eventually, usually when a trustee can no longer manage it, and a fund holding an illiquid property with a member in aged care is the hardest version of that problem.

The fee crossover is the easy half and it is the half everyone argues about. The question I would sit with is whether you want to be a trustee — filing an annual return, arranging an audit, and being personally responsible for the rules — every year for the next thirty. Plenty of people do and enjoy it. Nobody should discover they do not after establishing the fund.
FAQ
What super balance do I need to make an SMSF cost-effective versus an industry fund?
The balance where the SMSF's fixed annual costs equal the percentage the alternative charges. That is under $300,000 for a simple, cheaply administered fund and can be over $800,000 for one with an accountant, an adviser and a property.
What are the typical annual administration and audit costs of running an SMSF?
The unavoidable items are the supervisory levy, an annual independent audit and preparation of the financial statements and annual return. Beyond that, costs vary widely depending on whether administration is online or through an accountant.
Is an SMSF worth setting up for my super balance?
Only where there is a reason beyond fees — direct property, a specific estate structure, or a genuine preference for control. On cost alone, at a balance near the crossover, it is a job taken on for a small margin.
What are my obligations as an SMSF trustee?
Personal responsibility for the fund's compliance with superannuation law, including the sole purpose test, the in-house asset limits, the restrictions on acquiring assets from members and the arm's-length requirements. Penalties apply to trustees personally.
Can an SMSF own my business premises?
Yes. Business real property is the significant exception to the rule against acquiring assets from members, and it can be leased back to a member's business on arm's-length terms.
What happens if my SMSF breaches the rules?
The approved auditor is required to report contraventions to the ATO, which can apply administrative penalties, require rectification or education, or in serious cases make the fund non-complying — which has a severe tax consequence.
