An emergency fund is money you set aside for the things you can't plan for. The car needs a new transmission. The hot water system dies. You lose your job, or you can't work for a few weeks. It is not for a holiday or a new phone. It is the buffer that stops one bad week from turning into a debt you spend a year paying off.
How much you actually need
The government's Moneysmart guide suggests aiming for enough to cover three months of expenses (Moneysmart). Many financial advisers suggest working towards three to six months, depending on how secure your income is and how long it might take to find work again if you had to.
The important word there is expenses, not income. You are not trying to replace your whole pay. You are trying to cover the things you actually have to pay while everything else goes on hold.
Working out your number
The simplest way is to add up what you must spend in a month, then multiply.
Let's say your rent or mortgage is $2,200, food is $800, bills and rego and insurance come to $600, and the minimum on your debts is $400. That is $4,000 a month of essentials. Three months of that is $12,000, and six months is $24,000. Those are your two markers. It is a range, and where you sit in it is up to you.
Where most people are
If that number feels a long way off, you are not alone. Around 37% of Australians say they could not cover three months of essential costs from their savings (Finder, 2025), and only about 40% could live off their savings for three months or more if they suddenly lost their job (2025 survey data). So a fully stocked emergency fund is genuinely uncommon, which is exactly why having one puts you in a much stronger position than most.
Getting started
You do not need the whole amount before it starts working. The first $1,000 already covers a lot of the small disasters that would otherwise go on a credit card. From there, a set amount each payday into a separate savings account builds it quietly in the background. Keep it separate from your everyday account so you are not tempted to treat it as spending money, and keep it somewhere you can actually reach within a day or two if you need it.

- How much should I have in an emergency fund in Australia?
- The government’s Moneysmart guide suggests aiming for enough to cover three months of expenses, and many financial advisers suggest working towards three to six months depending on how secure your income is. It is based on your essential expenses, not your full income.
- How do I work out my emergency fund target?
- Add up what you must spend in a month — rent or mortgage, food, bills, insurance, rego and minimum debt repayments — then multiply. If your essentials come to $4,000 a month, three months is $12,000 and six months is $24,000. Where you sit in that range is up to you.
- Where should I keep my emergency fund?
- Keep it in a separate savings account from your everyday spending so you are not tempted to dip into it, but somewhere you can still reach within a day or two if you need it. You do not need the full amount before it helps — the first $1,000 already covers a lot of small emergencies.
