An emergency fund is the money that keeps a flat tire, a surprise medical bill, or a lost job from becoming a financial disaster. This shows how big yours should be, how far along you are, and how soon you can finish it.

Enter your essential monthly costs, choose a cushion, and you've got a plan.

The 2-minute guide

Why 3 to 6 months?

The classic target is 3–6 months of essential expenses, enough to cover rent, food, utilities and insurance if your income suddenly stops. Lean toward 3 if your job is very stable and you have a partner's income; lean toward 6–12 if you're self-employed, a single earner, or your income is unpredictable.

Count essentials, not everything

Your emergency number is built on needs, not your whole lifestyle. Include rent or mortgage, groceries, utilities, transportation, insurance and minimum debt payments. Leave out restaurants, vacations and subscriptions. In a real emergency, those pause.

Keep it separate and boring

Park this money in a high-yield savings account that's easy to reach in a day or two but annoying enough to access that you won't raid it for a sale. Keeping it out of your main checking account is what stops it from quietly disappearing.

Start before it's perfect

Don't wait until you can save the whole thing. A starter fund of even $1,000 covers most everyday surprises, and every month you add buys more peace of mind. Progress beats perfection here.

Frequently asked questions

How much should I have in an emergency fund?

Most guidance says 3–6 months of essential living expenses. If your monthly essentials are $3,500, that's roughly $10,500–$21,000. Freelancers and single-income households often aim higher, toward 6–12 months.

Where should I keep my emergency fund?

In a separate, FDIC-insured high-yield savings account, safe, earning some interest, and reachable within a day or two. Avoid tying it up in investments that can drop in value right when you need the cash.

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

A common approach is to save a small starter fund (around $1,000) first, then attack high-interest debt aggressively, then finish building the full 3–6 month fund. That starter cushion keeps a surprise from pushing you deeper into debt.
