How big should your emergency fund be, and where should you keep it?
An emergency fund is money set aside for surprises, like a car repair, a doctor bill or losing your job. It keeps you from using a credit card or selling investments at a bad time.
Key points
- Most people aim for 3 to 6 months of needed bills.
- A high-yield savings account is a good place to keep it.
- Start small. Even $500 helps.
How much do you need?
Add up your must-pay bills for one month: rent or mortgage, food, utilities, insurance, phone, car and minimum debt payments. Then multiply.
| Your situation | Common target |
|---|---|
| Steady job, two incomes | 3 months |
| One income or kids | 6 months |
| Self-employed or commission pay | 6 to 12 months |
| Planning to retire early | 1 to 2 years of spending in cash |
If your bills are $2,500 a month, 3 months is $7,500 and 6 months is $15,000.
Where to keep it
Your emergency fund should be safe and easy to reach. That's why many people use a high-yield savings account.
In September 2026, the average savings account paid 0.37%. Many high-yield accounts paid about 3.5%. On $15,000, that's about $525 a year instead of about $56.
- Good: high-yield savings, money market accounts.
- Okay for part of it: short CDs, if you keep enough in savings for quick needs.
- Not a good fit: stocks. They can be down right when you need the money.
How to build it step by step
- Save your first $500 to $1,000.
- Set up an automatic transfer every payday, even $25.
- Add surprise money, like tax refunds or bonuses.
- Keep going until you reach one month, then three, then six.
Should I invest or build my emergency fund first?
A common plan: build a starter fund, get your full 401(k) match, pay off high-interest debt, then finish your emergency fund. After that, invest more for the long term.
