Emergency Fund Calculator
Find your target emergency fund reserve based on your actual essential expenses, then see how long it will take to close the gap -- this calculator does the math for you.
Housing, food, utilities, insurance, transportation, minimum debt payments. Not your full lifestyle spending.
We'll suggest a coverage target below based on your answers -- you can always change it.
Common guidance: 3 months for stable dual-income households, 6 months as a general default or with dependents, 9 for self-employed or single-income, 12 for business owners.
Emergency funds are typically kept in a high-yield savings account for liquidity, not a CD.
| Savings gap remaining | $0.00 |

How to Use This Calculator
Enter your essential monthly expenses (not full lifestyle spending -- see the note below the field), then pick a coverage target of 3, 6, 9, or 12 months. Enter what you've already saved and how much you're contributing monthly, plus an expected APY. The result shows your target, the gap remaining, and how many months it will take to close it at your current pace.
How the Target Is Calculated
The core formula is simple: Target = Essential Monthly Expenses × Coverage Months. What takes more thought is the inputs -- essential expenses means what you'd actually spend in preservation mode if income stopped, not your current full lifestyle spending, and most people's essential floor runs 60-75% of their actual monthly spending. Time to goal is calculated the same way as the Savings Interest Calculator, applying your monthly contribution and APY until the balance reaches your target.
Frequently Asked Questions
How many months of expenses should I save?
3 months is common for stable dual-income households with no dependents, 6 months is the general default or if you have dependents, 9 months if self-employed or single-income, and 12 months for business owners. It depends on your risk tolerance and job stability.
Where should I keep my emergency fund?
Most guidance points to a high-yield savings account: FDIC-insured, liquid, and earning meaningfully more than a traditional account. See High-Yield Savings vs. CDs for why a CD's early withdrawal penalty makes it a weaker fit for money you might need on short notice.
Should I use my full monthly spending or just essentials?
Essentials only -- what you'd need in preservation mode if income stopped. This is typically 60-75% of full monthly spending for most households.
What if I can't hit my target quickly?
A partial emergency fund is still meaningful protection. Adjust the monthly contribution field above to see how a larger or smaller amount changes your timeline.
