How Much Should Be in Your Emergency Fund?
An emergency fund is money set aside specifically to cover essential living costs if something unexpected happens — job loss, a medical emergency, urgent home or car repairs. The standard guideline is to save enough to cover 3 to 6 months of essential expenses, though the right target depends on your personal circumstances.
The calculator above works this out instantly — just enter your monthly essential expenses and choose your target number of months.
What Counts as an "Essential Expense"?
The key to an accurate emergency fund target is using only essential expenses — the costs you absolutely must cover even with no income. Do not include discretionary spending like entertainment or dining out.
- Housing. Rent or mortgage payment, plus essential utilities like electricity, water and heating.
- Food. Groceries — a realistic, basic amount, not including takeaways or dining out.
- Transport. Fuel, public transport costs, or minimum car payment if you rely on a vehicle for work.
- Insurance. Health insurance, car insurance and any other essential insurance premiums.
- Minimum debt payments. The minimum required payment on any loans, credit cards or other debt.
- Essential subscriptions. Phone and internet, if needed for work or basic life admin.
How Many Months Should You Target?
| Situation | Recommended Target | Why |
|---|---|---|
| Stable job, dual income household | 3 months | Lower risk of both incomes stopping at once |
| Single income household | 6 months | No second income to fall back on if job is lost |
| Self-employed / freelance | 6-12 months | Income can be irregular or seasonal |
| Unstable industry or job market | 9-12 months | Higher risk of extended unemployment |
| Dependents (children, family) to support | 6-12 months | Higher fixed essential costs, less flexibility |
Where to Keep Your Emergency Fund
Your emergency fund should be kept somewhere safe and easily accessible — not invested in the stock market, where the value could drop right when you need the money most.
- Easy access savings account. The most common choice — funds are available within a day or two, with no penalty for withdrawal.
- High-yield savings account. Some banks offer better interest rates on easy-access accounts than standard current accounts, letting your emergency fund earn a little interest while it sits ready.
- Avoid locking it away. Fixed-term deposits or investment accounts aren't suitable for emergency funds since you may face penalties or losses if you need to withdraw at short notice.
Building Your Emergency Fund Alongside Other Goals
Most financial guidance suggests building a small starter emergency fund first (even just enough to cover a month), then prioritising any high-interest debt repayment, then building the rest of your emergency fund up to the full 3-6 month target. Once that's in place, other savings and investment goals can take priority. Our Budget Calculator can help you find room in your monthly budget to build this up consistently.
