What is Emergency Fund?
Easy-access savings covering 3 to 6 months of essential spending for unexpected events.
Full Definition
An emergency fund is a pot of readily accessible cash set aside to cover essential costs if income stops or an unexpected bill lands, such as job loss, illness or a major repair. The usual guidance is to hold 3 to 6 months of essential outgoings (rent or mortgage, bills, food, minimum debt payments), leaning towards six months if your income is irregular or you are self-employed. It is kept in instant-access savings rather than invested, so the money is there when needed even if returns are modest. Building it before investing is a cornerstone of personal finance.
How Emergency Fund is calculated
Target = Monthly essential expenses x months (3 to 6)
Shortfall = max(0, Target - Current savings)- Monthly essential expenses
- Rent/mortgage, bills, food and minimum debt payments only.
- months
- Desired coverage, typically 3 to 6.
Worked example: With GBP 1,800 of essential monthly costs and a 6-month goal, the target is 1,800 x 6 = GBP 10,800. With GBP 4,000 already saved, the shortfall is GBP 6,800.
