Why an emergency fund comes first

An emergency fund is cash set aside for the unexpected: a job loss, a medical bill, a car repair or a broken furnace. Without it, a surprise expense lands on a credit card at 20% or more, and a temporary setback becomes long-term debt. Federal Reserve surveys have repeatedly found that a sizable share of American adults could not cover a $400 emergency expense with cash or its equivalent.

How much to keep

  • Target = essential monthly expenses × months of coverage
  • Months to reach the goal = remaining amount ÷ monthly savings

Count only essentials: housing, utilities, groceries, insurance, transportation, childcare and minimum debt payments. Leave out restaurants, subscriptions and vacations, which you would cut in a real emergency.

Situation Suggested coverage
Stable job, two incomes, no dependents 3 months
Typical household 6 months
One income, dependents or a long job search in your field 9 months
Self-employed, commission or seasonal work 12 months

Worked example

Your essential expenses are $3,000 a month and you want 6 months of coverage. You already have $5,000 saved and can add $500 a month.

  1. Target = 3,000 × 6 = $18,000.
  2. Still to save = 18,000 − 5,000 = $13,000.
  3. Time to reach it = 13,000 ÷ 500 = 26 months.
  4. Today, your savings cover 1.7 months of expenses, 28% of the goal.

Where to keep it

The money must be safe and available within a day or two. Good options are high-yield savings accounts and money market deposit accounts, insured by the FDIC or NCUA up to $250,000 per depositor and bank. Money market funds and short-term Treasury bills also work for larger funds. Avoid stocks: they tend to fall during recessions, exactly when job losses are most common.

Building it faster

  • Automate a transfer on payday so the saving happens before spending.
  • Put windfalls such as tax refunds and bonuses straight into the fund.
  • Start with a $1,000 starter fund, pay off high-interest credit cards, then finish the full target.
  • Once you use the fund, rebuild it before resuming other goals.

Frequently asked questions

How big should an emergency fund be?

Most planners advise 3 to 6 months of essential expenses. With $3,000 of essential monthly costs, 6 months means $18,000.

Which expenses count?

Only the essentials you would still pay after losing your income: housing, utilities, groceries, insurance, transportation, childcare and minimum debt payments.

Where should I keep my emergency fund?

In a safe, liquid account such as a high-yield savings account or a money market account, insured by the FDIC or NCUA, not in stocks that could fall when you need the money.

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

A common approach is a starter fund of $1,000 to one month of expenses, then paying off high-interest debt, then completing 3 to 6 months of expenses.
