How Much Do I Need to Retire on $100,000 Per Year?
Most of us would be quite comfortable living on $100,000 per year in retirement. It is enough to cover living expenses, enjoy travel and spend quality time with family and friends—which is what retirement is all about, isn’t it?
But how much money do you actually need to retire on $100,000 a year?
In this article, we’re going to answer that exact question. We’ll also look at one of the most common reasons that people work years longer than they need to and potentially miss out on some of their best retirement years.
This article is general information only and does not constitute financial advice.
What standard of living could $100,000 provide?
Before looking at how much you need to retire on $100,000 per year, let’s consider the type of lifestyle that income might provide.
To give us some perspective, the Association of Superannuation Funds of Australia publishes quarterly retirement-standard figures. These are designed to help retirees estimate the income they may need to achieve their desired lifestyle.
For homeowners aged 65 to 84, the June 2026 figures indicate that a comfortable lifestyle costs approximately $56,166 per year for a single person and $78,998 per year for a couple.
Factors affecting the amount required
The amount you need will depend on:
– The age at which you retire.
– How long you want your money to last.
– Whether you are assessed as a single person or as a member of a couple.
– Whether you are a homeowner or non-homeowner for Age Pension purposes.
Let’s look at a range of retirement ages and how much you may need at each age to cover retirement expenses of $100,000 per year.
Retirement ages and the amount required
The following figures are illustrative estimates prepared in September 2026. They assume:
– A net investment return, after fees and taxes, of 5% per annum.
– Inflation of 2.5% per annum which is conservative.
– Spending of $100,000 per year in today’s dollars, increasing with inflation.
– All starting capital is assessable financial wealth.
– The retiree owns their home outright, with the principal residence excluded from the assets test.
– Age Pension eligibility begins at age 67.
– Age Pension rates, thresholds, taper rates and deeming rules effective from 20 September 2026 continue in real terms.
– Capital is progressively drawn down to approximately zero at the end of the selected period.
Actual outcomes will depend on investment returns, inflation, tax, fees, asset ownership, spending patterns, future government policy and longevity. Note that the modelling assumes smooth returns and capital being exhausted, with no allowance for sequencing risk, a bequest or living beyond the selected period.
Under these assumptions, if you are single and want to retire at age 60 on an income of $100,000 per year, you would need approximately:
– $1.41 million for your money to last 20 years.
– $1.99 million for your money to last 30 years.
– $2.45 million for your money to last 40 years.
For a single person retiring at age 65 or 67, the estimates are approximately the same under this model. This is because the starting balances are above the Age Pension cut-off and the Age Pension does not begin to contribute until the portfolio has reduced later in retirement.
For a homeowner couple retiring at age 60 and wanting a combined income of $100,000 per year, you would need approximately:
– $1.14 million for your money to last 20 years.
– $1.64 million for your money to last 30 years.
– $2.17 million for your money to last 40 years.
For a couple retiring at age 65, the corresponding estimates are approximately $999,000, $1.64 million and $2.17 million.
For a couple retiring at age 67, they are approximately $966,000, $1.64 million and $2.17 million.
Why does a couple need less than a single person?
It may seem counterintuitive that a couple needs less capital than a single person, but there is a reason.
A couple may be eligible to receive more in combined Age Pension payments than a single person. Remember, we are solving for a total income of $100,000. It does not matter whether that supports one person, two people or six people … the target is still $100,000.
However, more people may receive more Age Pension in total, meaning they require less from their investments.
Why is there little difference between retiring at 60 and 65?
For single retirees, there is little difference between retiring at age 60, 65 or 67 under this model.
For couples, retirement age makes a noticeable difference to the 20-year estimate, because a couple beginning at age 65 or 67 can access a part Age Pension sooner as their assessable assets reduce.
For the 30 and 40 year estimates, the starting capital is high enough that the portfolio initially exceeds the Age Pension assets-test cut-off. Age Pension payments only become relevant later, after the balance has fallen. That is why the estimated starting capital is similar across the different retirement ages for those longer periods.
There would generally be a more noticeable interaction with the Age Pension if the target income were lower.
What if the Age Pension is excluded?
What if you are not eligible for Age Pension payments or you simply want to exclude them from your calculations? How much would you need to fund an income of $100,000 per year?
If you were not eligible for the Age Pension, the calculations below assume a net investment return of 5% per annum and inflation of 2.5% per annum, with spending increasing in line with inflation.
The amount is the same for single people and couples, regardless of retirement age, because the Age Pension is not included.
You would need:
– $1.59 million for your money to last 20 years.
– $2.13 million for your money to last 30 years.
– $2.56 million for your money to last 40 years.
Why some people work longer than necessary
$100,000 would provide most people with more than a comfortable retirement income … often more than they actually need.
This brings me to one of the most common reasons people work years longer than necessary and miss out on some of their best retirement years: they aim for a retirement income that is higher than they actually need.
People will often say, “I want $100,000 per year,” without relating that amount to their personal circumstances.
But are you sure you really need $100,000?
I’m not saying you don’t. I could spend $100,000 without any trouble (we love camping so splash out on camping items!) … But there is a catch.
The difference between funding expenses of $100,000 per year and $70,000 per year can amount to hundreds of thousands of dollars in additional starting capital. In some longer-term scenarios it can exceed $1 million, but it is not automatically a $1 million difference.
How many additional years might you need to work to accumulate that extra capital … and would the additional spending materially improve the retirement you want?
The problem with targeting a retirement income higher than you actually need is that you may miss out on your best retirement years.
Your retirement-income objective should be based on your personal goals, the lifestyle you want and the amount required to achieve those objectives. That is what matters.
This is where working with a financial adviser is ideal to create and optimise your personal retirement plan.
The important point is that your retirement-income target should reflect the life you genuinely want to fund … not an arbitrary number. A clear, personalised plan can help you understand when you have enough and make your retirement decision with greater confidence.
