Your FIRE Number in Australia [2026]

Your FIRE number is the amount of money you need invested so that the returns cover your living expenses forever — or at least long enough that you'll never run out. The standard formula is simple: annual spending divided by your safe withdrawal rate.

If you spend $60,000 a year and use a 4% withdrawal rate, your FIRE number is $1.5 million. Spend $80,000? You need $2 million. The maths is straightforward — it's the execution that takes years.

In Australia, there's a twist that makes FIRE different from the US version: superannuation. You can't touch your super until preservation age (60 for most people), so you need enough outside super to bridge the gap from when you quit working until you can access your super balance.

This is where Australian FIRE gets complicated. If you want to retire at 40, you need 20 years of living expenses in non-super assets before you can touch your super at 60. That's $1.2 million in accessible investments just for the bridge period (at $60,000/year spending).

Meanwhile, your super keeps compounding untouched for those 20 years. A $200,000 super balance at age 40 grows to roughly $540,000 by age 60 at 5% real returns — without you adding a cent. So your FIRE plan needs two buckets: the bridge fund (accessible money) and the super fund (locked until 60).

The bridge amount is the present value of your spending from retirement until preservation age. Our FIRE Calculator models this explicitly, showing you how much needs to be outside super versus inside.

Here's what the numbers look like for different spending levels, assuming a 4% safe withdrawal rate:

$40,000/year (lean FIRE): FIRE number $1,000,000. Achievable for singles in regional areas or couples who've paid off their home.

$60,000/year (regular FIRE): FIRE number $1,500,000. Comfortable for a couple in most cities. Covers housing costs, food, transport, health insurance, and modest travel.

$80,000/year (fat FIRE): FIRE number $2,000,000. Private school for kids, regular overseas holidays, newer cars. This is roughly the median household income.

$100,000/year (premium FIRE): FIRE number $2,500,000. Top 20% spending. Requires either a very high income, a very long accumulation phase, or both.

The biggest factor isn't your income — it's your savings rate. Someone earning $100,000 who saves 50% ($50,000/year) reaches FIRE faster than someone earning $200,000 who saves 20% ($40,000/year).

At a 30% savings rate with 7% nominal returns, starting from zero at age 30 on a $100,000 salary, you'd reach a $1.5M FIRE number by around age 47. Bump that savings rate to 50% and you're there by 41. At 60%, you could be financially independent by 38.

These numbers include employer super contributions (12% SG) growing separately. The super component does heavy lifting in the background — it just isn't accessible until later.

Coast FIRE means you have enough invested right now that compound growth alone will reach your FIRE number by a traditional retirement age — without adding another dollar. If you need $1.5M at age 60 and you're 35 with $400,000 invested at 5% real returns, you're Coast FIRE. You still need to cover current expenses, but you don't need to save any more.

Barista FIRE means working part-time (enough to cover living expenses) while your investments grow. Named after the idea of working a stress-free barista job, it's popular with people who don't want to grind to full FIRE but want out of corporate life.

Both are milestones on the path to full FIRE and can dramatically change how you think about work.

The 4% rule comes from the Trinity Study, which found that a 4% initial withdrawal rate adjusted for inflation survived 30 years of US market history 95% of the time. But Australia's market is different: smaller, more concentrated, with different tax structures.

Research by Morningstar and Vanguard suggests that a 3.3-3.7% withdrawal rate is more appropriate for Australian retirees planning for 40+ years. That said, the Age Pension acts as a floor — even if investments underperform, most Australian residents will qualify for at least a partial Age Pension from age 67.

Our FIRE Calculator lets you adjust the withdrawal rate so you can see the difference between an aggressive 5% and a conservative 3.5%.
