Coast FIRE and Barista FIRE in Australia: Do You Need to Retire Fully?

By Mitchell Shad  ·  8 October 2026  ·  7 min read

A full FIRE number can feel out of reach. If you spend $80,000 a year, the usual "× 25" rule points at $2 million, and that is a long way from where most people start. Two variations exist for exactly that reason: Coast FIRE and Barista FIRE. Both lower the number you need to hit by letting work, or time, do part of the job.

Both are estimates built on assumptions, not promises. Returns are not guaranteed and nothing here is financial advice. See how to work out the full number first in how to calculate your FIRE number in Australia.

Coast FIRE: let compounding finish the job

You have reached Coast FIRE when the money you have already invested would, left alone, grow to your full freedom number by a normal retirement age. You still work, but only to pay today's bills. You no longer need to save for the future.

The arithmetic is a discount, run backwards:

Coast number = freedom number ÷ (1 + real return) ^ years until retirement

An illustration, using round numbers and a 5% real (after inflation) return:

• Freedom number: $2,000,000
• Years until a retirement age of 60: 25
• Coast number: $2,000,000 ÷ 1.05^25 ≈ $590,000

So someone with roughly $590,000 invested, who then adds nothing, would be on track for $2 million in 25 years under that assumption. Change the return to 4% and the coast number climbs to about $750,000. The answer is very sensitive to the return you assume, which is why you should test a few.

The Australian twist: super counts, but only on one timeline

Much of an Australian's Coast FIRE money is already in superannuation, and super compounds with employer contributions you do not have to think about. That helps. But it is locked until preservation age (60 for anyone born after 30 June 1964), so it can only fund the part of life after that.

Which means there are really two pots to coast:

• Super coasts toward age 60 and beyond.
• Money outside super has to carry you from the day you stop working until super opens up.

If your whole coast number is in super, you can legitimately coast, but you cannot retire early on it.

Barista FIRE: part-time work covers the gap

Barista FIRE means leaving a demanding full-time career for lower-pressure, lower-paid work (the name comes from the café job) while your investments cover the rest of your costs.

Barista number = (annual spending − part-time income) × 25

Using the same $80,000 spend:

• Part-time income: $35,000
• Gap the portfolio must cover: $45,000
• Barista number: $45,000 × 25 = $1,125,000

Compared with $2 million, that is a lot closer. Part-time income also tends to be taxed lightly, and many people find the structure good for their wellbeing. The risk is that the income has to genuinely continue. If it dries up, your real number is the larger one.

The bridge: the gap Australians cannot ignore

Whichever style you pick, if you stop full-time work before 60, you need accessible wealth to bridge until super unlocks. A simple check:

1. Work out your annual spending until 60.
2. Multiply by the number of years until 60.
3. Compare it to the wealth you hold outside super (shares, ETFs, cash, investment property equity you can actually use).

The family home usually does not count, and equity is only useful if you can access it, which is why we separate net worth from usable equity. From the Age Pension age onward (67), the Age Pension may reduce how much your own investments need to carry, subject to the income and assets tests.

Which one fits you?

Work out your own numbers

Generic calculators ask you to guess a single "investments" figure. The harder, more useful job is to know what you actually hold: what is in super, what is outside it, what is usable equity and what is not.

That is what Compound is built for. It brings property, super, shares and ETFs, cash and crypto into one view across every entity you own them in, then projects the year your investments could fund your life, modelled for Australian tax, capital gains and super staying locked until 60. You can try the engine in the FIRE calculator, see how it works on the Freedom Year feature page, or track the whole picture with the net worth tracker.
