What This Calculator Does

An emergency fund is the cash cushion that keeps a job loss, medical bill, or surprise repair from turning into long-term debt. This calculator sizes that cushion based on your essential monthly expenses and how many months of coverage you want.

Enter what you already have saved and how much you can add each month, and it shows your funding progress, how many months you're currently covered, and a realistic timeline to reach your full target.

Formula

Target = Monthly Essentials × Months of Coverage

Most households target 3-6 months. The calculator then divides the remaining gap by your monthly contribution to estimate a funding timeline.

  • EssentialsNon-discretionary monthly costs you can't cut
  • CoverageMonths you want the fund to last (3-6 typical)
  • ContributionAmount you add to the fund each month

Examples

Example: $3,200/month essentials, 6 months of coverage

Target = 3,200 × 6 = $19,200. You have $4,000 saved and add $400/month.

Gap = $15,200; covered ~1.3 months today; fully funded in about 38 months (3y 2m) of $400 contributions.

Example: leaner 3-month target

Same $3,200 essentials but a 3-month goal = $9,600, with $4,000 saved and $400/month.

Gap = $5,600; fully funded in about 14 months — a faster, lower starting target for stable dual-income households.

Methodology

Target = monthly essential expenses × months of coverage. Months covered = current savings ÷ monthly essentials. Time to goal = remaining gap ÷ monthly contribution (contributions only; interest is treated as a buffer).

Frequently Asked Questions

How much should I have in an emergency fund?+

3 to 6 months of essential expenses. Dual-income, stable jobs → 3 months may suffice; single income, variable pay, or self-employed → aim for 6 months or more.

Where should I keep it?+

Somewhere safe and liquid — usually a high-yield savings account (4-5% APY in 2026). Don't invest emergency money in stocks or lock it in CDs you can't access without penalty.

Emergency fund or debt payoff first?+

Build a ~$1,000 starter fund, then attack high-interest debt, then finish the full 3-6 month fund. The starter fund stops a surprise expense from adding new debt.

What counts as essential expenses?+

Housing, utilities, groceries, insurance, transportation, minimum debt payments, childcare. Exclude dining out, subscriptions, travel, and shopping.
