How much should an emergency fund be?

A common UK suggestion is three to six months of essential costs, for example in NS&I's emergency fund guide, which cites MoneyHelper. There's no single right figure, and it doesn't have to be your first goal if you're just starting out. A smaller cushion built now is better than a perfect one you never begin.

What counts as essential spending

Count what you'd have to keep paying if your income stopped: housing, utilities, food, transport to work, insurance, minimum debt payments and childcare. Leave out holidays, eating out and subscriptions you could cancel. Using essentials rather than your usual spending makes the target smaller and more realistic.

Where to keep it

Somewhere you can reach quickly without risking the value, such as an easy-access savings account. Compare the interest rate, and check how the account is protected before you choose.
