Emergency Fund Calculator

Enter your essential outgoings and target buffer to size your emergency fund.

Estimate for general information only — not financial, tax or legal advice. Always check the official figures (GOV.UK / HMRC) or speak to a qualified adviser before making decisions.

An emergency fund is easy-access cash to cover life's surprises — a job loss, a boiler breakdown, a car repair — without reaching for credit. A common target is three to six months of essential outgoings (rent or mortgage, bills, food, transport). This tool sizes your target and shows how much further you have to go.

Frequently asked questions

How many months should I save?

Three months is a solid start; six is safer, especially with a single income or variable earnings. Self-employed people often aim higher.

Where should I keep it?

In an easy-access savings account — safe, separate from your current account, and reachable within a day or two when you need it.
