Emergency Fund Calculator: Your Real Target

Use this emergency fund calculator to size your safety net based on monthly essentials. The standard target is 3–6 months of expenses; high-volatility incomes should aim for more.

How this calculator works

An emergency fund is sized by months of essential expenses, not income. Essentials are the bills you can't cancel quickly — rent or mortgage, utilities, food, insurance, and minimum debt payments. Discretionary spending (subscriptions, dining out, gym memberships) is excluded because those are the first things you'd cut in an actual emergency.

The target formula

target = monthly_essentials × months_of_buffer

How many months you need

3 months — dual-income household with one stable salaried job. The second income covers the gap if one earner loses work.
6 months — single-income household with stable employment. The standard CFPB and FDIC recommendation.
9 months — variable income (sales commission, tipped, partial 1099). Smooths out lumpy earnings.
12 months — self-employed, single-income, or in a high-volatility industry. Job-search timelines are longer at senior levels and in narrow specialties.

Where to keep it

Park the fund in an FDIC-insured high-yield savings account — fully liquid, government-insured up to $250,000 per depositor, and currently earning 4–5% APY. Not a CD (early-withdrawal penalty), not in stocks (could be down 30% the day you need it), not in checking (0% APY).

FAQ

How much should an emergency fund be?

Three to six months of essential monthly expenses for a stable single-earner household. Dual-income with one stable job can get away with 3 months. Self-employed, freelance, or single-income high-volatility workers should target 9–12 months. Calculate from your essentials, not from your full lifestyle spending.

Where should I keep my emergency fund?

A high-yield savings account is the standard — fully liquid, FDIC-insured up to $250,000, and earning 4–5% APY in 2026. NOT in a CD (penalties for early withdrawal), NOT in stocks (could be down 30% the moment you need it), and NOT in checking (0% APY).

Should I build an emergency fund before paying off debt?

Most planners recommend a small starter fund of $1,000–$2,000 first, then aggressive debt payoff, then build the full 3–6 months once high-rate debt is cleared. The starter fund prevents new credit-card debt when an emergency hits during the payoff phase.

How long will it take to build a 6-month emergency fund?

At a $300/month contribution against a $21,000 target (6 × $3,500), you'll hit it in 70 months — roughly 5.8 years. Doubling the contribution to $600 cuts that to 35 months. The calculator above gives you the exact timeline once you enter your numbers.
