Emergency Fund Calculator
Calculate the right size for your emergency fund based on monthly expenses, family situation, and job security.
What this calculates
An emergency fund is the financial cushion that keeps a job loss, medical bill, or major repair from turning into debt. The standard advice — 3–6 months of expenses — is a rough average. Your real target depends on income stability, dependents, insurance coverage, and how easily you could replace your job. This calculator dials in a specific number.
Formula & how it works
Base = monthly_expenses × months_target. Months target varies: 3 months for single, dual-income, stable job. 6 months for primary breadwinner or family. 9–12 months for self-employed, commission-based, or volatile industry. This calculator lets you set the multiplier directly.
Worked example
Monthly expenses $4,500, single income, stable corporate job. Standard 6-month target = $27,000. Self-employed with same expenses: 9-month target = $40,500. Cut to bone-minimum expenses ($3,000/mo): same job, $18,000 target.
Frequently asked questions
Where should I keep this money?
High-yield savings account at an FDIC-insured (US) or equivalent bank. 4–5 % APY is currently available. Not in stocks, not in a 401k, not somewhere with withdrawal friction.
Build before paying off debt?
Build a small $1,000–$2,000 starter fund first to avoid putting emergencies back on the cards. Then attack high-interest debt aggressively. After the debt is gone, build the full 3–6 month fund.
Does retirement count?
No. Withdrawing from a 401k pre-59 hits a 10 % penalty plus tax. Even a Roth IRA's contributions (which are penalty-free) shouldn't be a planned emergency source — they're the very lowest of last resorts.
What counts as monthly expenses?
Everything you can't avoid for 6 months: rent/mortgage, food, transport, insurance, minimum debt payments, utilities, basic medical. Not vacations, restaurants, subscriptions you'd cut, or new clothes.
