How it works

An emergency fund covers the bills you can't skip if your income stops or a big surprise cost hits. The calculator adds up your essential monthly costs and multiplies them by a number of months that depends on how steady your income is.

Target = essential monthly costs × months of cover

3 months if two incomes or a very secure job make a long gap unlikely.
6 months for one steady income: the most common guideline.
9 to 12 months if your income swings, you're self-employed, or others depend on you alone.

Worked example

Essentials of $3,500 a month with one steady income: $3,500 × 6 = $21,000.

With $4,000 saved and $400 added each month, it takes 43 months without interest, or 39 months in an account paying 4% APY.

Where to keep it

Somewhere safe and quick to reach: a high-yield savings or money market account, insured by the FDIC or NCUA.
Not in stocks. Emergencies often come with market drops, the worst time to sell.
Separate from everyday spending, so it doesn't quietly become the holiday fund.

Questions people ask

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

A common approach is a starter fund of one month's essentials, then high-interest debt, then the full fund. The debt payoff planner shows how fast the debt could go.

Is $1,000 enough?

It's a good first milestone that covers many surprise bills, like a car repair or a medical copay. It won't cover a job loss, so keep building toward your full target.

What counts as an emergency?

Job loss, urgent medical or dental costs, essential car or home repairs, emergency travel. Planned costs like holidays or a new phone are better handled with their own savings.
