Emergency Fund Calculator
An emergency fund is cash set aside for unexpected expenses or loss of income. This calculator helps you determine the appropriate size of your emergency fund based on your monthly expenses and chosen coverage period. Enter your average monthly expenses and select how many months of coverage you want (3, 6, 9, or 12 months). The calculator shows your target amount and can estimate monthly savings needed to reach it over a chosen timeline.
Emergency fund formula
Emergency Fund = Monthly Expenses × Months of Coverage
Amount to Save = Target Amount - Current Savings
This simple formula multiplies your essential monthly expenses by your desired number of months of coverage.
How to use this calculator
- Calculate your essential monthly expenses: rent, utilities, food, insurance, minimum debt payments, and basic necessities only.
- Enter this amount in the "Monthly expenses" field.
- Select your desired months of coverage (3, 6, 9, or 12 months). 6 months is a typical recommendation.

Emergency fund calculator: frequently asked questions
How many months of expenses should I have?
Financial advisors typically recommend 3 to 6 months of living expenses. If you have a stable job, 3 months may be adequate. If you are self-employed, have variable income, or dependent on a single income, 6 to 12 months is more prudent.
What counts as an emergency expense?
Emergency fund covers essential expenses only: rent or mortgage, utilities, food, insurance, minimum debt payments, and medical costs. It does not include vacation, entertainment, or non-essential shopping.
Should I include debt payments in my monthly expenses?
Include only minimum debt payments (e.g., credit card minimums, loan payments) in your emergency fund calculation. This allows you to meet basic obligations if income stops. After the emergency, pay down debt aggressively.
Where should I keep my emergency fund?
Keep it in a liquid, low-risk account: high-yield savings account, money market account, or short-term CD. Avoid investments that can lose value when you need cash quickly.
How do I build an emergency fund if I have no savings?
Start small: save 1,000 dollars first, then build toward 1 month of expenses, then 3 months. Use the savings-goal-calculator to plan automatic monthly deposits.
