How Much Should You Have in an Emergency Fund?
Three to six months of essential expenses is the usual guideline — here's how to work out your number and where to keep it.
An emergency fund is money set aside purely to cover the unexpected — a boiler breaking, a job loss, an emergency vet bill — so you're not reaching for a credit card or a loan when life throws a curveball.
The standard guideline: 3–6 months of essential expenses. Essential expenses means rent or mortgage, bills, food, and transport — not your full lifestyle spend. If your essential outgoings are £1,200 a month, you're aiming for roughly £3,600–£7,200.
Where you sit on that range depends on your situation:
- Stable employment, dual income household → closer to 3 months.
- Self-employed, variable income, or sole earner → closer to 6 months (or more).
Where to keep it. An emergency fund needs to be accessible, not locked away or invested in the stock market where it could drop in value right when you need it. An easy-access savings account or easy-access Cash ISA is the usual home for it.
Building it from nothing. Don't wait until you can save the full 3–6 months in one go. Start with a smaller milestone — £500 or £1,000 — then build from there with automatic transfers on payday.
The psychological win. Beyond the maths, an emergency fund reduces financial stress significantly — knowing a surprise bill won't derail your month is worth more than the interest it earns.
