An emergency fund is cash you set aside for job loss, medical bills, car repairs and other surprises, so they do not end up on a credit card. The right size depends on your essential expenses and how secure your income is. This emergency fund calculator turns your bills into a target, shows how many months you are covered today and how long it will take to get there.

Counts essential expenses only, the bills you would still pay after losing your income. Interest compounds monthly at the monthly equivalent of the APY; deposits at the end of each month.
Key takeaways
- Target = essential monthly expenses × months. Essentials of $3,100 a month and a six-month goal mean a $18,600 fund.
- With $2,000 saved and $300 a month at 4% APY, the example reaches the goal in 50 months; at $500 a month it takes 32 months.
- Three months is a common minimum with stable income; six months or more makes sense with one income or dependents, and up to a year for the self-employed.
- In the Federal Reserve's 2025 survey, 63% of adults said they would cover a $400 emergency with cash or its equivalent.
Step 1: Count only essential expenses
An emergency fund has to cover the bills you could not stop if your income disappeared: rent or mortgage, utilities, groceries, transportation, insurance, minimum debt payments and child care. Leave out savings contributions, dining out, travel and subscriptions you would cancel. This keeps the target realistic.
Step 2: Choose how many months
| Your situation | Months to consider |
|---|---|
| Two stable incomes, no dependents | 3 months |
| One income, or children or other dependents | 6 months |
| Commission, seasonal or gig income | 6 to 9 months |
| Self-employed or a small business owner | 9 to 12 months, plus a separate tax reserve |
| Close to retirement or a single earner with a mortgage | 6 to 12 months |
These are guidelines, not rules. A job in a field with long hiring times, a health condition or an older car are good reasons to aim higher. More on sizing in how much to keep in an emergency fund.
The example
| Months of expenses | Target with $3,100 a month |
|---|---|
| 3 months | $9,300 |
| 6 months | $18,600 |
| 9 months | $27,900 |
| 12 months | $37,200 |
The $2,000 already saved covers 0.6 months. Saving $300 a month in an account paying 4% APY, the fund reaches $18,600 in 50 months and earns about $1,624 in interest along the way. Raising the monthly amount to $500 shortens that to 32 months.
Where to keep your emergency fund
- High-yield savings account: the usual choice, liquid and FDIC or NCUA insured; see high-yield savings accounts.
- Money market account: similar, sometimes with check writing; see money market vs. savings.
- No-penalty CD or Treasury bills for the part you are unlikely to need quickly.
- Not in stocks: an emergency often coincides with a falling market.
How to build it faster
- Start with a mini goal of $500 to $1,000 to handle small surprises.
- Automate a transfer on payday; the budget calculator helps you find the amount.
- Send windfalls such as tax refunds and bonuses straight to the fund.
- Refill it after you use it, before resuming other goals.
Frequently asked questions
Is $10,000 a good emergency fund?
It depends on your expenses. With essentials of $3,100 a month, $10,000 covers about three months. Divide your fund by your monthly essentials to see your coverage.
Should I pay off debt or build an emergency fund first?
A common approach is a small starter fund first, then high-interest debt, then the full emergency fund, so a surprise does not push you back into debt.
Does my emergency fund count toward retirement savings?
No. Keep them separate so you never have to withdraw retirement money, which can trigger taxes and penalties.
What counts as an emergency?
Job loss, urgent medical or dental bills, essential car or home repairs and emergency travel. Planned costs such as vacations or holiday gifts belong in their own savings goal.
Is interest on an emergency fund taxable?
Yes, interest is taxed as ordinary income in the year it is credited.
