Emergency Fund Calculator
Calculate how much you need in an emergency fund based on your monthly expenses, and how long it'll take to reach the goal.
3-6 months is typical; higher for unstable income
How to use this calculator
Enter your true monthly expenses (rent/mortgage, utilities, food, insurance, minimums on any debt — not lifestyle extras you could cut). Pick how many months of coverage you want. Enter what you already have saved and what you can realistically contribute each month. The calculator shows your target, shortfall, and how long to reach full funding.
Why "3-6 months of expenses"
The median US job search takes 2-4 months. Adding a cushion for setup time (unemployment paperwork, finding temporary work, or simply time to breathe) pushes the target to 3-6 months for most people. If your role is specialized or you're in a field with longer hiring cycles, err toward 6-9 months.
Starting from zero
If you have no emergency fund today, don't be intimidated by the full target. Start with $1,000 as a short-term goal — usually 1-3 paychecks of focused saving. That covers most common emergencies and gets you out of the constant paycheck-to-paycheck-to-credit-card cycle. Then pay down high-interest debt, then finish building to the full 3-6 months.
Where to park it
High-yield savings accounts currently yield 4-5% APY — keeping pace with typical inflation and earning you a few hundred dollars per year on a modest balance. Good choices: Ally, Marcus, Capital One 360, Discover, SoFi, Wealthfront (cash account). Avoid: checking accounts (often 0% or near-zero), long CDs (liquidity matters), stocks or crypto (volatility defeats the purpose).
When to replenish
After you use the fund (car repair, medical, job loss), rebuilding is the top financial priority until you're back to full coverage. Cut extras and divert the savings there. Treat an empty emergency fund like a fire in the kitchen — everything else waits.
Frequently asked questions
How many months should my emergency fund cover?▾
The common rule is 3-6 months of expenses. Stick with 3 months if your income is very stable (government job, tenured position, dual high earners). Aim for 6 months for most W-2 roles. Go 9-12 months for commission sales, freelance/self-employment, or single-income households with dependents.
Should emergency fund track expenses or income?▾
Expenses, not income. If you earn $8,000/month but only spend $4,500, you need 3-6× $4,500 ($13,500-$27,000) — not 3-6× your income. The fund covers what you'd need to keep the lights on during a job gap, not your total lifestyle.
Where should I keep an emergency fund?▾
High-yield savings account (HYSA) or money market account. Target 4-5% APY currently. The key properties: FDIC-insured, available within 1-3 business days, no penalty for withdrawal, not subject to market volatility. Never put emergency money in stocks.
What counts as an 'emergency'?▾
Unexpected and necessary. Job loss, medical bills not covered by insurance, major car or home repairs required to maintain function, emergency travel for a family crisis. NOT: vacations, a deal on a new TV, a birthday gift, normal car maintenance, tax bills you knew were coming.
Should I pay off debt first or build the fund?▾
Build a starter fund of $1,000-$2,000 first, then throw everything at high-interest debt (over 10% APR), then finish building the full 3-6 month fund. Without the starter buffer, any minor surprise sends you back into debt — the classic debt-payoff trap.
