Emergency Fund
Plain-English definition of Emergency Fund — part of our saving glossary.
Definition
An emergency fund is cash set aside specifically for income interruption or unexpected major expenses — typically 3–6 months of essential outgoings, kept in an instant-access or short-notice savings account.
Worked example
If essential outgoings are £2,400/month, a 3-month emergency fund is £7,200 and a 6-month fund is £14,400. Keep this in a separate instant-access savings account — somewhere one tap removed from the current account.
Why it matters
Savings are the foundation of everything else — you cannot invest, buy a home, or weather a redundancy without a cash buffer. Even modest sums build meaningful resilience if they are parked in the right wrapper and left alone.
Common mistake
Leaving large balances in a current account earning 0–1% is one of the most expensive "default decisions" in personal finance. Over a few years, the opportunity cost versus a simple easy-access account regularly runs into the hundreds of pounds per £10,000 held.
