Emergency Fund Calculator
Calculate your ideal emergency fund size based on your monthly expenses and see how long it will take to reach your goal. Track your progress toward 3, 6, 9, or 12 months of savings.
How This Calculator Works
Two simple calculations here. First, your target: monthly essential expenses times your months of coverage. Second, your timeline: how many months of steady saving it takes to close the gap between what you’ve got and that target.
Target = monthly essential expenses × months of coverageMonths to fully funded = (target − current savings) ÷ monthly contribution. “Essential” means the bills that don’t stop in an emergency: housing, food, utilities, insurance, and minimum debt payments — not your full lifestyle spending.
Assumptions baked into the math
- Only essential expenses count toward the target, so your emergency number is smaller than your normal monthly budget.
- Interest earned along the way is ignored — in a high-yield savings account it’s a bonus that gets you there a bit sooner.
- You contribute the same amount every month.
A worked example
With $4,000/month in essential expenses and a 6-month cushion, your target is $24,000. If you’ve saved $6,000 and add $500/month, you’re 25% funded today and fully funded in 36 months. Bump the contribution to $750/month and that drops to 24 months.
Frequently Asked Questions
How much should I have in my emergency fund?
Most financial experts recommend 3-6 months of essential expenses. If you have a variable income, are self-employed, or have dependents, aim for 6-12 months. Your emergency fund should cover housing, food, utilities, insurance, and minimum debt payments.
Where should I keep my emergency fund?
Keep your emergency fund in a high-yield savings account (HYSA) where it earns interest but remains instantly accessible. Avoid investing it in stocks or locking it in CDs — the whole point is liquidity when you need it most.
What counts as a financial emergency?
True emergencies include job loss, major medical bills, urgent home or car repairs, and unexpected family obligations. Planned expenses (vacations, holidays, annual insurance premiums) should be saved for separately in a sinking fund.
Should I pay off debt or build an emergency fund first?
Start with a $1,000-$2,000 starter emergency fund to avoid going deeper into debt when surprises hit. Then aggressively pay off high-interest debt. Once high-interest debt is gone, build your full emergency fund.
