How Much Should You Keep in an Emergency Fund?

An emergency fund is cash set aside for surprises, like a car repair, a medical bill or a gap in income. How much you need depends on your life, but there is a simple way to set a target and a realistic way to reach it.

What an emergency fund is for

The Consumer Financial Protection Bureau (CFPB) describes it as a cash reserve set aside for unplanned expenses or financial emergencies. Without one, even a minor shock can turn into debt. If you cover a surprise with a credit card or a loan, the original bill can grow because of interest and fees, and debt tends to be harder to pay off than the surprise was to cover.

How much do you need?

You will often see "three to six months of essential expenses" as a rule of thumb. It is a reasonable place to start, but it's not an official standard. The CFPB says the right amount depends on your situation. It suggests thinking about the most common unexpected expenses you've had before and what they cost, and it points out that even a small amount can provide some security.

A practical way to set your target:

Essential expenses are the ones you can't skip: housing, utilities, food, transportation, insurance and minimum debt payments. Choose more months if your income is irregular, if you have dependents, or if your job would be hard to replace quickly. Choose fewer if you have a stable income and other safety nets.

A worked example

Suppose essential expenses are $2,500 a month, you have $1,500 saved and you can put away $250 a month:

How to build it

The CFPB describes several strategies. You can use more than one:

• Make saving a habit. Set a specific goal, contribute a set amount on a schedule and check progress regularly.
• Automate it. A recurring transfer from checking to savings makes contributions consistent. Watch your balance so an automatic transfer doesn't cause an overdraft.
• Save through work. If you get paid by direct deposit, ask your employer whether you can split your paycheck between two accounts.
• Use windfalls. A tax refund or a cash gift can kick-start the fund.
• Manage cash flow. Adjusting bill due dates or tracking when money comes in and goes out can free up small amounts to save.

If a full target feels out of reach, start smaller. A first goal of one month of essentials, or even one common surprise expense, is still progress. Build your budget first if needed with the 50/30/20 rule.

Where to keep it

The CFPB suggests keeping the money safe, accessible and somewhere you're not tempted to spend it. Options include a bank or credit union account, a prepaid card or cash. Cash can be lost or stolen. Money you may need quickly is usually not a good fit for investments that can lose value.

Deposits at an FDIC-insured bank are insured up to at least $250,000 per depositor, per insured bank, per ownership category. Credit unions are insured separately by the NCUA. See the FDIC's deposit insurance FAQ. A savings account that pays a higher rate helps your fund grow, so compare accounts using APY. See APR vs. APY.

When to use it

Decide in advance what counts as an emergency, so the fund doesn't slowly disappear into everyday spending. A car repair, an uninsured medical bill or a loss of income qualify. A sale doesn't. And don't be afraid to use it when you need it. If you spend it down, rebuild it.
