An emergency fund is the foundation of financial security—money set aside for unexpected expenses or income loss. This calculator helps you determine the right emergency fund size and creates a plan to build it.
How This Calculator Works
This calculator builds your emergency fund plan:
- Monthly Expenses: Your essential monthly costs
- Months of Coverage: How many months you want covered (typically 3-6)
- Current Savings: What you've already saved
- Target Amount: Your emergency fund goal
- Monthly Savings: How much to save each month
- Timeline: When you'll reach your goal
The Formula Explained
Emergency Fund = Monthly Essential Expenses × Months of Coverage
Remaining to Save = Target - Current Savings
Months to Goal = Remaining / Monthly Savings Amount

Frequently Asked Questions
What is an emergency fund?
An emergency fund is money set aside for unexpected expenses or income disruption—not a vacation fund or down payment savings. It protects you from going into debt when life happens: job loss, medical emergencies, car repairs, or home issues. It's your financial safety net.
How much should I have in an emergency fund?
Standard advice: 3-6 months of essential living expenses. Single income household or unstable job? Aim for 6+ months. Dual income, stable employment? 3 months may suffice. Self-employed or commission-based? Consider 6-12 months. The right amount lets you sleep at night.
Should I include all expenses or just essentials?
Calculate based on essential survival expenses only: housing, utilities, food, transportation, insurance, minimum debt payments. Entertainment, dining out, and subscriptions would be cut in a real emergency. This keeps your target realistic and achievable.
Where should I keep my emergency fund?
Keep it in a high-yield savings account—liquid, FDIC insured, and earning interest. Don't invest emergency funds in stocks (too volatile when you might need them). Don't lock them in CDs (withdrawal penalties). Balance accessibility with earning some return.
Should I build an emergency fund before paying off debt?
Yes—at least a starter emergency fund of $1,000-2,000. Without any cushion, every unexpected expense goes on credit cards, perpetuating debt cycles. Build the starter fund, then attack high-interest debt, then complete the full 3-6 month fund.
How long should it take to build an emergency fund?
Depends on your savings capacity and goal. Aim for 12-24 months to complete a full fund. Save faster by treating it as a bill (automatic transfers), using windfalls (tax refunds, bonuses), and temporarily reducing discretionary spending. Slow and steady wins.
When should I use my emergency fund?
Use it for true financial emergencies: job loss, medical emergencies, essential home/car repairs, unexpected essential travel (family emergency). Don't use it for: vacations, wants, predictable annual expenses (those need separate sinking funds), or things you just forgot to budget.
How do I rebuild my emergency fund after using it?
Treat replenishment as priority one—before extra debt payments or new savings goals. You're now vulnerable without the fund. Cut discretionary spending temporarily, redirect any extra income, and rebuild as quickly as reasonably possible. The peace of mind is worth accelerating this.
Key Points to Remember
- 3-6 months minimum: More for single income, self-employed, or unstable jobs
- Essential expenses only: Calculate what you'd actually spend in an emergency
- High-yield savings: Liquid, safe, earning interest
- Build before debt payoff: At least a starter fund first
- Replenish quickly: Rebuilding after use is priority one
