How much should be in an emergency fund?

Target = Essential monthly costs Γ— months of cover Each month: Fund = Fund Γ— (1 + monthly interest) + amount you save

Only count costs you'd still have if you lost your income: housing, utilities, food, transportation, insurance and minimum debt payments. Leave out dining out, subscriptions you'd cancel and savings contributions.

Example: essentials of $3,000 a month ($1,500 rent, $250 utilities, $500 groceries, $350 transportation, $200 insurance and $200 of minimum payments) and 6 months of cover means a target of $18,000. With $5,000 saved and $500 a month going into a 4% savings account, you'd reach it in 25 months.

Choosing 3, 6 or 12 months

Three months can be enough for a household with two stable incomes and good job security. Six months is the usual advice. Single-income households, commission or seasonal workers, and anyone in a field where job searches take longer should aim higher, and the self-employed often keep 9 to 12 months because income can stop without notice.

Keep the money somewhere safe and easy to reach, like a high-yield savings or money market account, not in stocks that might be down when you need them. If the full target feels far off, start with a $1,000 starter fund so a car repair doesn't go on a credit card, then build from there.

Frequently asked questions

How much should I have in my emergency fund?

Three to six months of essential expenses for most people, and more if your income is irregular or you're the only earner. With $3,000 of monthly essentials, that's $9,000 to $18,000.

Where should I keep my emergency fund?

In a federally insured high-yield savings or money market account that you can reach in a day or two, separate from your everyday checking so it isn't spent by accident.

Should I save an emergency fund or pay off debt first?

Many planners suggest a small starter fund of about $1,000 first, then paying off high-interest debt, then building the full fund. Without any cushion, a surprise bill usually ends up back on a credit card.
