A $100,000 retirement income is well above what most superannuation benchmarks assume you will actually need.
But it is also the number a lot of Australians aim towards.
So what balance gets you there?
The answer is more encouraging than you might expect, though it does demand some planning.

What the superannuation benchmarks actually say
The Association of Superannuation Funds of Australia publishes the country's most widely used retirement budgets.
For the March quarter of 2026, its comfortable standard sits at $55,923 a year for a single person and $78,566 for a couple.
The modest standard is much lower, at $36,434 and $52,473 respectively.
ASFA estimates a single homeowner needs a lump sum of $630,000 to fund a comfortable retirement, while a couple needs $730,000.
Those figures assume a 6% investment return alongside some Age Pension support.
A $100,000 income is therefore roughly 80% above the comfortable benchmark for a single retiree.
It also sits well beyond the point where the Age Pension assets test offers any assistance at all.
The maths behind $100,000 a year
Once you retire and convert your balance into an account-based pension, the government sets minimum withdrawal rates.
For anyone aged between 65 and 74, that minimum is 5% of the balance each year.
Running that calculation in reverse gives you the following figures.
A balance of $2 million drawn at 5% produces exactly $100,000 a year.
That is the headline answer.
For a couple the burden is shared, so around $1 million each achieves the same household income.
It is worth remembering that earnings inside a retirement phase pension are generally tax free, and so are the withdrawals for anyone over 60.
A $100,000 pension income is consequently worth a great deal more than a $100,000 salary.
Where the transfer balance cap fits in
There is a ceiling on how much you can move into that tax-free environment.
From 1 July 2026, the general transfer balance cap rose to $2.1 million per person.
This means that at the 5% minimum drawdown rate, a fully used $2.1 million cap generates $105,000 a year.
The system is effectively designed to support roughly this level of income for one retiree.
How much superannuation you would realistically need
The honest answer is around $2 million in superannuation for a single retiree.
A couple targeting the same household income needs a similar amount between them.
That may seem like a daunting figure against the average balance, which sits closer to $308,600 for Australians aged 70 to 74.
Getting there with ASX shares
This is where growth assets do the heavy lifting.
The Vanguard Australian Shares Index ETF (ASX: VAS) is the most popular way Australians own the local market.
It tracks the S&P/ASX 300 Index (ASX: XKO) across more than 300 holdings and charges just 0.07% a year.
Since inception the fund has returned an average of roughly 9.22% annually.
At that rate, $500,000 invested at age 45 would grow to about $2 million by age 61 without a single extra contribution.
Compounding, rather than the size of your contributions, does most of the work.
Foolish takeaway
Retiring on $100,000 a year is achievable, but it takes roughly $2 million and a long runway.
The good news is that superannuation remains one of the most tax-effective structures available to Australian investors.
Start early, keep your fees low, and let the market do the compounding for you.
The difference between a modest retirement and a comfortable one is usually decided decades before you stop working.
