How it works

Target = monthly essential expenses × months chosen. Time to goal uses your monthly deposit with deposits at the end of each month and no interest: (target − already saved) ÷ deposit, rounded up to a whole month.

Worked example

Essentials of $2,500 a month and 3 months chosen: $2,500 × 3 = $7,500. With $1,500 saved and $250 deposited each month, ($7,500 − $1,500) ÷ $250 =24 months . Choosing 6 months instead makes the target $15,000.

About “how many months”

You may have seen a rule of thumb for how many months to save. We do not repeat one here, because we have not found an official source (CFPB, FDIC or the Federal Reserve) that states a single number. The CFPB’s own guide says the right amount depends on your situation.

Frequently asked questions

How many months should I save?

We do not recommend a number. The CFPB says the amount you need in an emergency fund “depends on your situation.” Pick the number of months that fits yours: how steady your income is, who depends on you, and how much your essentials cost.

What counts as an essential expense?

Costs you would still have to pay if your income stopped: typically housing, utilities, groceries, transportation to work, insurance and minimum debt payments. You decide what belongs on your list.

What is an emergency fund for?

The CFPB describes it as savings for unplanned bills outside your routine monthly spending. Its examples include car repairs, home repairs, medical bills and a loss of income.

What if I can only save a little each month?

A small amount still helps. The CFPB says even a small amount can provide some financial security, and that saving consistently is the key. The tool shows how long your amount takes.

Does this count interest?

No. It uses deposits only, which keeps the answer cautious. To include interest, use the high-yield savings calculator.

Where should I keep it?

Somewhere you can reach quickly and that is not exposed to market swings. Deposits are insured to at least $250,000 at each FDIC-insured bank; see the FDIC page.
