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.

Worked example

With $2,750 of essential monthly costs, 6 months of cover is $16,500. With $3,000 saved and $400 added a month, you get there in 34 months.
