Emergency Fund Calculator
Find out how big your emergency fund should be and how long it will take to build.
How much should an emergency fund be?
Most experts suggest three to six months of essential spending. Choose six or more if your income is irregular, you are the only earner or you work in an unstable field. Only count needs, such as housing, food, transport, insurance and minimum debt payments.
Where to keep it
Use an easy-access, insured savings account. The money should be safe and available, not invested for growth.
