Multiple Super Accounts: How a Forgotten Fund Costs $125,000 🇦🇺
An average worker who unknowingly keeps just one extra super account charging $100 in annual fees and $315 in insurance premiums from age 27 to 67 can end up with around $125,000 less at retirement, purely from duplicated costs and missed compounding.
The number that matters
$100M — extra system-wide cost per year — ASFA, 2023
The Association of Superannuation Funds of Australia (ASFA) estimates that unwanted multiple super accounts cost the system about $40 per extra account per year, adding up to roughly $100 million in additional costs annually based on around 2.5 million unwanted accounts by 2022.
How it quietly costs you
Mechanism: duplicated fees on multiple accounts
- According to the ATO, around 4 million Australians held two or more super accounts as at June 2025.
- Each extra account typically charges its own administration and investment fees, even if the balance is small.
- ASFA estimates each unwanted extra account adds about $40 per year in marginal costs to the system, which translates to extra fees and lower net returns for members overall.
Personal impact example
- UniSuper models that paying an additional $100 admin fee per year on a second account from age 27 to 67 (40 years), with 2.5% fee inflation and net investment returns of 6.3% p.a., can reduce a member’s retirement balance by up to $25,000.
- This assumes:
- Admin fee = $100 per year, increasing with inflation at 2.5% p.a.
- Net investment return = 6.3% p.a. in a roughly balanced option.
Old vs better comparison
-
Old/typical behaviour:
-
A worker changes jobs and is defaulted into their new employer’s fund.
-
They leave a small balance in the old fund (e.g. $5,000) paying, say, $100 in admin fees per year and percentage-based investment fees.
-
Over decades, that account remains open, charging fees and possibly insurance premiums, even if they never look at it.
-
Better behaviour:
-
The worker consolidates that $5,000 into their main fund using ATO online services in myGov and closes the duplicate account.
-
They now pay one set of admin and investment fees, so the entire balance compounds at the net investment rate instead of being eroded by duplicated fees.
The key loss mechanism is simple: every extra account means another standing fee line item that compounds against you instead of for you.
The second, compounding trap
Mechanism: duplicated and often unwanted insurance premiums
- It is common for super funds to automatically include default insurance, usually life and TPD (total and permanent disability), sometimes income protection.
- If you have multiple accounts, you may be paying insurance premiums in each fund, often without realising and without needing multiple overlapping cover amounts.
- UniSuper’s modelling shows that adding insurance premiums of $315 per year on a second account from age 27 to 67, increasing with wage inflation at 4.0% p.a., on top of duplicated admin fees, can reduce retirement savings by a further $100,000 depending on investment returns.
- Combined, their scenario of $100 admin fee + $315 insurance premium per year on a second account for 40 years at 6.3% net returns leads to a total impact of roughly $125,000 less at retirement.
Why it compounds so much
- Every dollar of premium taken out of super is a dollar that does not earn investment returns for decades.
- With 6.3% net returns p.a., a $315 annual premium from age 27 to 67, escalating with wage inflation, becomes a substantial opportunity cost; UniSuper’s modelling quantifies this as roughly $100,000 in lost retirement balance for a second unnecessary cover over 40 years.
Contrast vs doing one review and rationalising cover
- If you keep only one well-chosen policy through a single super fund:
- You pay premiums once, not twice or three times.
- You can tailor cover amounts to your needs instead of accepting small default cover in multiple funds.
- This eliminates the duplicated $315+ per year in the example, protecting around $100,000 of retirement savings over a working life.
What this looks like in practice
Persona
- Name: Jess
- Age: 32
- Job: Marketing manager
- Income: $95,000 per year (taxable salary; typical mid-career professional)
- Super:
- Main fund: $55,000 balance in a balanced option.
- Old fund from a previous job: $8,000 balance.
- Account type: Industry super funds with default insurance in both.
- Years to retirement: Planning to retire at 67, so 35 years to go.
Jess has no idea she has two accounts; she only checks the main fund and assumes “the ATO and my employer sort the rest out”.
Discovery 1 — Duplicate admin fees
- By logging into myGov > ATO > Super > Manage, Jess sees two eligible super accounts under her TFN.
- The old fund’s Product Disclosure Statement reveals an admin fee of $104 per year (example consistent with “around $100” cited in UniSuper’s modelling).
- Using UniSuper’s modelling basis (admin fee of $100 p.a., 2.5% fee inflation, 6.3% net returns), Jess realises that keeping this second account from age 32 to 67 could cost her around $16,000–$20,000 in retirement savings (slightly less than the full 40-year $25,000 figure, because her period is 35 years instead of 40).
Comparison: vs consolidating now and paying one admin fee, freeing that $8,000 to compound without duplicated fixed fees.
Discovery 2 — Duplicate insurance premiums
- Jess notices she is being charged default life and TPD premiums in both funds, totalling about $340 per year across the two accounts (consistent with UniSuper’s modelling of $315 p.a. for the second account).
- Applying UniSuper’s scenario (second-account premiums of $315 p.a. escalating with 4% wage inflation, earning 6.3% net return over 35 years), Jess sees she could lose roughly $80,000–$90,000 in retirement savings from unnecessary duplicate insurance alone (proportionally less than the 40-year $100,000 figure).
Comparison: vs holding a single, appropriately sized cover in one fund and investing the saved premiums, preserving tens of thousands for retirement.
Discovery 3 — System-wide trap scale
- Reading ASFA’s analysis, Jess learns that unwanted multiple accounts fell from about 11.5 million in June 2015 to around 4.5 million in June 2020, with further reduction to around 2.5 million by 2022 due to consolidation and “Your Future, Your Super” reforms.
- ASFA estimates the additional marginal cost per unwanted account is about $40 per year, which totals around $100 million per year system-wide.
- Given around 4 million Australians had two or more super accounts in 2025, Jess realises she is part of a large group quietly subsidising these extra costs through duplicated fees.
Comparison: vs the ideal of one well-managed super account per person for most workers, significantly reducing aggregate system costs and increasing average balances.
The full cost of doing nothing
Using Jess’s profile and the UniSuper assumptions:
-
Admin fee impact:
-
Second account admin fee: $100 per year, 2.5% inflation, 6.3% net returns.
-
From age 32 to 67 (35 years), this models to roughly $16,000–$20,000 loss, based on scaling down the $25,000 loss over 40 years that UniSuper calculates for ages 27–67.
-
Insurance impact:
-
Second account insurance premiums: $315 per year, 4% wage inflation, 6.3% net returns.
-
Over 35 years, proportionally scaled from UniSuper’s $100,000 loss over 40 years, this implies roughly $80,000–$90,000 in lost retirement balance.
-
Combined lifetime cost for Jess (admin + insurance on the second account):
-
Approximate range: $96,000–$110,000 by age 67.
-
Central illustrative figure: about $100,000 lost, purely from keeping an unnecessary second account with default insurance and fixed admin fees, under the given assumptions.
Modelling basis
- Second account charges:
- $100 admin fee p.a., inflation 2.5%.
- $315 insurance premium p.a., wage inflation 4.0%.
- Net investment return: 6.3% p.a. balanced option.
- Time horizon: 35 years (age 32–67).
- Estimates are extrapolated from UniSuper’s 40-year projections; exact outcomes vary with market returns and actual fee structures.
What to do about it
Move 1 — Check for multiple super accounts
-
Action: Log into myGov and use ATO Online Services to see all super accounts in your name.
-
Tool/portal:
- myGov linked to ATO Online Services.
- Navigate: myGov > ATO > Super > Manage.
- Steps (under 30 minutes):
- Create or sign in to your myGov account.
- Link your account to the ATO if not already linked.
- Go to Super, then Manage to view all eligible super accounts listed against your TFN.
- What “good” looks like:
- For a typical employee, seeing one primary accumulation super account with a sensible balance and contributions flowing in from your current employer.
- Multiple small, inactive accounts are a red flag for consolidation.
Move 2 — Compare fees and insurance across your funds
-
Action: Download each fund’s fee and insurance details and compare total yearly costs.
-
Tool/portal:
- Fund Product Disclosure Statement (PDS) and annual statement (accessible via each fund’s online portal).
- Use ASIC’s Moneysmart guidance to understand fee types and insurance through super.
- Steps:
- Log in to each super fund’s online account and download the latest statement and PDS.
- Identify:
- Admin fee (e.g. $100 p.a.),
- investment fees (% of balance),
- insurance premiums (e.g. $315 p.a.).
- Add up total yearly costs per account and highlight any duplicated insurance or fixed fees for small balances.
- What “good” looks like:
- One fund with transparent admin fees, competitive investment fees, and a single, appropriate insurance package.
- No small “forgotten” account paying extra fixed admin fees and default insurance premiums.
Move 3 — Consolidate your super into your chosen main fund
-
Action: Use ATO’s “Transfer super” function to consolidate extra accounts into your preferred fund.
-
Tool/portal:
- ATO Online Services via myGov, using the Transfer super function.
- Steps:
- In myGov, go to ATO > Super > Manage.
- Select “Transfer super” — this option appears only if you have more than one eligible super account.
- Choose the fund you want to keep as your main account and authorise the transfer of balances from other accounts into that fund.
- What “good” looks like:
- After processing (usually within a few days), you see a single active super account with the combined balance.
- Your employer contributions are directed to that account, and you have one set of admin fees and one insurance arrangement to manage.
A myth worth clearing up
Myth: “Having multiple super funds is safer because if one performs badly or collapses, I’ve got another one as backup.”
Fact:
- Super investments are already diversified within a single fund’s investment option, and super funds are regulated by ASIC, APRA and the ATO; spreading small balances across multiple accounts mostly increases duplicated fees and insurance premiums, not safety.
- ASFA finds that unwanted multiple accounts add around $40 per account per year in extra system costs, totalling around $100 million annually, which ultimately reduces members’ net returns.
- UniSuper’s modelling shows one extra account with $100 admin fee and $315 insurance premium per year over 40 years can cut your retirement balance by around $125,000, demonstrating that the “safety” of extra accounts is an expensive illusion.
