Your emergency fund target should be based on your monthly essential expenses, not your income. The standard range is 3–6 months of essential expenses, with the right amount depending on your employment type and household situation.


Step 1 — Calculate Your Monthly Essential Expenses

Add up the following costs per month:

CategoryYour amount
Rent or mortgage repayment
Groceries
Utilities (electricity, gas, water)
Internet and phone
Transport (fuel, public transport, rego monthly equivalent)
Health insurance
Home and contents / car insurance
Minimum loan repayments
Total monthly essentials

Leave out: dining out, subscriptions, entertainment, clothing (beyond basics), gym.


Step 2 — Choose Your Multiplier

Your situationMultiplierReasoning
Dual income, stable salaried jobs (government, corporate)× 3Lower risk — two incomes means one job loss doesn’t stop the household
Single income household, stable job× 4–5One income source means job loss = full financial shock
Casual, part-time, or contract work× 5–6Income can disappear quickly; gaps between contracts possible
Self-employed or freelance× 6–12Income is highly variable; slow months may follow good months

Step 3 — Your Emergency Fund Target

$$\text{Target} = \text{Monthly essentials} \times \text{Multiplier}$$

Examples:

ScenarioMonthly essentialsMultiplierTarget
DINK couple, both salaried$4,500× 3$13,500
Single person, stable job, Sydney$3,200× 4$12,800
Single parent, part-time work$2,800× 6$16,800
Freelancer, variable income$3,000× 9$27,000

What to Do Once You Know Your Target

  1. Open a separate high-interest savings account (named “Emergency Fund” — keep it psychologically separate from your everyday money)
  2. Set a starter target — $1,000–$2,000 first, as a buffer for smaller emergencies
  3. Automate a fortnightly or monthly transfer from your transaction account to the emergency fund on payday
  4. Direct windfalls (tax refunds, bonuses, gifts) to the emergency fund until the target is reached
  5. Redirect those transfers to investments or other goals once the fund is full

Starter Emergency Fund vs Full Emergency Fund

If you have high-interest debt (credit cards, personal loans), it may not make sense to save a full 6-month emergency fund before tackling that debt. A common approach:

StageAction
Stage 1Save $1,000–$2,000 starter emergency fund
Stage 2Pay off high-interest debt aggressively
Stage 3Build full 3–6 month emergency fund
Stage 4Invest for long-term goals

Where to Keep Your Emergency Fund

In Australia, a high-interest savings account (HISA) is the most appropriate home for an emergency fund. Look for:

  • A competitive interest rate (currently 4.5–5.5% p.a. at the time of writing — rates change with the RBA cash rate)
  • No monthly fees
  • Easy withdrawal without penalty
  • APRA-regulated institution (up to $250,000 per account holder is government-guaranteed under the Financial Claims Scheme)

FAQ

Can I split my emergency fund across multiple accounts? Yes — some people keep 1 month of expenses in a quick-access savings account and the rest in a slightly higher-rate account. The priority is accessibility, so keep the majority accessible within 1–2 business days.

Does super count as an emergency fund? No — superannuation is inaccessible before age 60 (with very limited exceptions). Never factor super into your emergency fund planning.

What if I can’t afford to save 3–6 months of expenses right now? Start small. Even $50–$100 per fortnight adds up. A $1,000 starter fund covers most common small emergencies and is a meaningful safety net.
