Emergency Fund Calculator UK
An emergency fund protects you from the unexpected — job loss, a broken boiler, car repairs, or a sudden expense. Without one, even a small shock can push people into debt. This calculator shows how large your fund should be and how long it will take to build it.
How much emergency fund should you have in the UK?
Most financial planners suggest saving between three and six months of essential living expenses — the amount that covers rent or mortgage, food, utilities, and transport if your income stopped suddenly.
- 3 months may be enough for dual-income households in stable employment, where the risk of both incomes stopping at once is lower.
- 6 months is a commonly cited figure for most households — it covers the average time it takes to find new employment and handle a significant unexpected cost.
- 9–12 months is often suggested for self-employed workers, freelancers, or single-income families where income is less predictable or a gap could last longer.
An emergency fund is generally kept in an easy-access savings account, so it remains available immediately without penalties for withdrawal. The right amount depends on your personal situation — job security, income type, dependants, and existing financial commitments.
The figures above are general guidance for illustration only and do not constitute financial advice. Your own circumstances will determine the right level of cover for you.
