How much emergency savings do you need?

An emergency fund is cash set aside for unplanned expenses and income interruptions — a job loss, a medical bill, a car repair. This calculator adds up your essential monthly costs, multiplies them by the number of months you want covered and compares the target with what you have already saved.

It also estimates how long it will take to reach the goal with regular monthly deposits, including the interest your savings account pays along the way.

Choosing your number of months

Suggested emergency fund size by situation
Situation	Suggested coverage
Two stable incomes, no dependents	3 months
One stable income or dependents	4–6 months
Self-employed, commission or seasonal income	6–12 months
Homeowner with older home or vehicle	Add a separate repair fund

How to build it faster

Automate a transfer to savings on every payday.
Send windfalls — tax refunds, bonuses, gifts — straight to the fund.
Keep the money in a high-yield savings account so it earns a competitive rate.
Pause extra spending categories until you hit your first milestone.

Frequently asked questions

How many months of expenses should an emergency fund cover?

Three to six months of essential expenses is the most common guideline. Aim toward six months or more if you are self-employed, have an irregular income, are the only earner in your household or work in an industry with frequent layoffs.

Which expenses count as essential?

Count what you must pay even in a crisis: housing, utilities, groceries, insurance, transportation, minimum debt payments and childcare. Leave out dining out, vacations and other spending you would cut in an emergency.

Where should I keep an emergency fund?

In a separate, federally insured savings account that is easy to reach but not linked to your everyday debit card — a high-yield savings account is a common choice because it pays more interest while keeping the money available.

Should I save for emergencies or pay off debt first?

Many people build a small starter fund (for example, one month of expenses) first, then focus on high-interest debt, then finish the full emergency fund. Without any cushion, a surprise bill often ends up back on a credit card.
