How Much Emergency Fund Do I Need?
The usual guideline is three to six months of essential spending. Not three to six months of salary, and not three to six months of everything you spend, just the stuff you'd still have to pay if your income stopped tomorrow. For many households that's a smaller number than they fear. And if even that feels out of reach, a starter fund of $1,000 or £1,000 covers most of the small emergencies that otherwise end up on a credit card.
Work out your essential monthly spending
Go through the last couple of months of bank statements and add up only what you couldn't easily cut:
- Rent or mortgage
- Utilities, council tax or property tax, phone and internet
- Groceries (basic ones, not takeaways)
- Insurance premiums
- Minimum debt payments
- Transport to work
- Childcare and any other non-negotiables
Leave out subscriptions, eating out, holidays and savings contributions. In a real emergency, those pause. Say your essentials come to $2,800 a month. Three months is $8,400; six months is $16,800.
Three months or six?
Lean towards three months if you have a stable job, two incomes in the household, good sick pay, and skills that are in demand. Lean towards six months, or more, if:
- You're self-employed or on commission, so income is lumpy anyway
- You're the only earner, or you have dependants
- Your industry has frequent layoffs or long hiring cycles
- You own a home or an older car, both of which break in expensive ways
How long will it take to build?
Using the $2,800 example and a savings account paying 4%:
- A $1,000 starter fund at $150 a month takes about 7 months.
- Three months ($8,400) at $400 a month takes about 21 months.
- Six months ($16,800) at $400 a month takes about 40 months.
That can feel slow. It's fine. Every month you add to it, the chances of a surprise bill turning into debt go down. The savings goal calculator shows the monthly amount for any target and deadline.
Where to keep it
Your emergency fund needs to be safe and easy to reach, in that order. Earning interest is a nice bonus, not the goal.
- A high-yield or easy-access savings account is the usual home. Keep it at a different bank from your current account if you're tempted to dip into it.
- Protection: in the US, FDIC insurance covers up to $250,000 per depositor, per bank, per ownership category. In the UK, the FSCS protects up to £120,000 per person, per banking licence, following the increase that took effect on 1 December 2025.
- Not in the stock market. Emergencies and market crashes have a habit of arriving together, often because of the same recession.
Emergency fund vs paying off debt
If you have credit card debt at 20%+, it's tempting to throw everything at the debt and skip the emergency fund. The problem is the next flat tyre goes straight back on the card. A common approach is to build the $1,000 starter fund first, then attack high-interest debt, then come back and finish the full three to six months. We cover the trade-off in should I pay off debt or save first?
What counts as an emergency?
Job loss, urgent medical or dental bills, essential car or home repairs, emergency travel for family. Things that are both unexpected and necessary. Christmas, annual insurance premiums and car tax aren't emergencies; they're predictable bills that happen to come once a year. Those are better handled with a sinking fund, so they don't drain your safety net.
Refill it after you use it
Using your emergency fund means it worked. Just make topping it back up the next priority, before you restart extra debt payments or saving for fun things.
Frequently asked questions
How much should I have in an emergency fund?
Three to six months of essential expenses, such as housing, utilities, food, insurance, transport and minimum debt payments. Start with $1,000 or £1,000 if the full amount feels far off.
Should my emergency fund be 3 or 6 months?
Three months can work with stable income and two earners. Aim for six or more if you're self-employed, the only earner, or work in an unstable industry.
Where should I keep my emergency fund?
In an easy-access, insured savings account, separate from your everyday account. Avoid investing it in stocks, which can fall just when you need the money.
Is the FSCS limit £85,000 or £120,000?
The FSCS deposit protection limit rose from £85,000 to £120,000 per person, per banking licence, on 1 December 2025.
