Learning how to build an emergency fund starts with a simple idea: set aside cash now so that a car repair, a medical bill or a lost paycheck does not push you into debt later. The Consumer Financial Protection Bureau (CFPB) describes an emergency fund as cash kept specifically for unplanned expenses and financial emergencies.
This guide turns official guidance from the CFPB, the Federal Deposit Insurance Corporation (FDIC), the IRS and the SEC’s Investor.gov into a step-by-step plan. It covers setting a target, where to keep the money, automating your savings, using tax refunds and other windfalls, and rebuilding after you use the fund.
Key takeaways
- There is no single right amount. The CFPB says your target depends on your situation, and its Rainy Day Fund tool suggests $500 as a starting goal.
- Keep the fund somewhere safe and easy to reach, such as a federally insured bank or credit union account, ideally separate from your everyday spending.
- Automatic transfers and a split direct deposit can make saving a regular habit.
- A tax refund can be direct deposited into up to three accounts, which makes it easier to send part of it straight to savings.
- Decide in advance what counts as an emergency, and make a plan to rebuild the fund after you use it.
Why an emergency fund matters
According to the CFPB’s essential guide to building an emergency fund, even a small financial shock can set you back if you have no savings. Common examples include car repairs, home repairs, medical bills and a loss of income. Without a cushion, people may turn to credit cards or loans, which can become harder to repay, or take money out of retirement savings.
Investor.gov, the SEC’s investor education site, makes a similar point. It describes “rainy day” savings as money that keeps you from borrowing when something unexpected comes up. It also warns that interest charges on a credit card balance may far exceed what you could earn on savings or investments.
Step 1: Set a realistic savings target
The CFPB does not set one dollar amount or a fixed number of months of expenses for everyone. It says the amount depends on your situation. A practical way to start is to think about the unexpected costs you have faced in the past and what they cost.
If you are starting from zero, a smaller first goal can help. The CFPB’s “Building your savings? Start with small goals” booklet includes a Rainy Day Fund tool that suggests $500 as a starting emergency target. You can adjust it to fit your needs. Once you reach your first goal, the CFPB suggests celebrating and then setting a new one.
Turn your goal into a weekly amount
The CFPB booklet suggests a simple formula: divide your total goal by the number of weeks you want to save. That gives you a weekly amount to aim for.
| Hypothetical goal | Weeks to save | Amount per week |
|---|---|---|
| $400 | 20 | $20 |
| $500 | 25 | $20 |
| $500 | 50 | $10 |
| $1,000 | 40 | $25 |
These figures are examples only. The first row is the example the CFPB uses, and the others apply the same arithmetic. The CFPB also offers a savings planning tool, linked from its emergency fund guide, to estimate how long reaching your goal may take.
Step 2: Find money to save
Before you can automate savings, you need to know where the money will come from. The CFPB suggests:
- Track your spending for a week to see where you could cut back.
- Map your cash flow. Note when money comes in and when bills go out, since a timing mismatch can leave you short even when your monthly income covers your bills.
- Ask about due dates. Some creditors, such as landlords, utilities and card issuers, may agree to move a due date so bills line up better with paydays.
- Save extra in better weeks. In weeks when you have more left over, move the extra into savings.
The CFPB booklet gives a cash-flow example: splitting a $700 rent payment into two $350 payments on the 1st and 15th, if your landlord agrees, can free up money early in the month.
Step 3: Choose where to keep your emergency fund
The CFPB says an emergency fund should be safe and easy to reach, but not so easy to spend that you use it for things that are not emergencies. It describes a bank or credit union account as generally one of the safest options, and it notes that a dedicated account just for emergencies can help. The CFPB booklet compares common choices:
| Option | Advantages | Drawbacks |
|---|---|---|
| Bank account | Federally insured, easy to access | May have fees |
| Credit union account | Federally insured, often lower fees | May have fewer branches |
| Prepaid card | Convenient, PIN-protected, you can only spend what is loaded | Fees, no branches |
| Cash at home | No account costs | Not protected from loss, fire or theft |
Investor.gov notes that bank and credit union savings accounts are typically federally insured and usually pay some interest. It also mentions high-yield savings accounts as a place for money you may need to reach quickly.
Check that your deposits are insured
According to the FDIC’s “Deposit Insurance At A Glance”, the standard insurance amount is $250,000 per depositor, per insured bank, for each account ownership category. FDIC insurance covers deposit products such as checking accounts, savings accounts, money market deposit accounts and certificates of deposit (CDs) at insured banks. It does not cover stocks, bonds, mutual funds, crypto assets, life insurance policies or annuities.
You can check whether a bank is insured with the FDIC’s BankFind tool at fdic.gov or by calling 1-877-ASK-FDIC (1-877-275-3342). For a full explanation of ownership categories and coverage, read our guide to FDIC insurance.
Step 4: Automate your savings
Automation means you save before you have a chance to spend. The CFPB suggests these approaches:
- Set up a recurring transfer. Ask your bank or credit union to move a fixed amount from checking to savings on a schedule, such as each payday.
- Split your direct deposit. If your employer allows it, send part of each paycheck straight to your savings account.
- Keep an eye on your checking balance. Use balance alerts or calendar reminders so an automatic transfer does not cause an overdraft fee.
- Track your progress. Balance alerts or a running total can keep you motivated.
The CFPB recommends making consistent contributions, such as a fixed amount per day, week or payday, and saving more when you are able.
Step 5: Put tax refunds and windfalls to work
Money that arrives outside your regular paycheck can give your fund a boost. The CFPB suggests saving all or part of a tax refund, holiday money or a birthday gift.
For federal tax refunds, the IRS says direct deposit can send your refund to one, two or three accounts. You can split it in tax software, or on Form 8888 if you file a paper return. For example, if a hypothetical refund were $1,200, you could direct $400 to your emergency savings account and the remaining $800 to checking. The CFPB booklet suggests dividing a refund among savings, current expenses and something for yourself.
The CFPB booklet also mentions Series I savings bonds as a government-backed savings option. The IRS notes that paper I bonds could be bought with a refund only until January 1, 2025. Electronic I bonds are now bought through TreasuryDirect. Read our guide to I bonds and TreasuryDirect before deciding whether they suit any part of your savings.
Step 6: Know when to use the fund, and rebuild it
The CFPB suggests setting your own rules for what counts as an emergency and applying them consistently. The fund can also cover costs that are not true emergencies but would otherwise go on a credit card, such as a medical bill that insurance does not cover. The CFPB notes that the interest and fees on credit cards or loans can make a bill grow significantly.
The CFPB booklet treats using your fund for an unexpected expense as a success, since that is its purpose. After you use it, make a plan to refill it. A simple approach is to restart or increase your automatic transfer until the balance is back to your target.
If the emergency is a job loss, your savings may need to stretch while you look for new work. Our guide on how to file for unemployment benefits explains how to apply in your state. While job hunting, watch for postings that ask you to pay upfront or share bank details. Our guide on how to spot a fake job offer covers the warning signs.

Frequently asked questions
How much should I keep in an emergency fund?
The CFPB does not set a single figure. It says the right amount depends on your situation and suggests looking at the unexpected expenses you have had before. Its Rainy Day Fund tool suggests $500 as a starting goal, which you can raise once you reach it.
Where is the safest place to keep emergency savings?
The CFPB describes a bank or credit union account as generally one of the safest options. Deposits at FDIC-insured banks are covered up to $250,000 per depositor, per insured bank, for each account ownership category. Cash at home has no account costs but is not protected from loss, fire or theft.
Can I send part of my tax refund straight to savings?
Yes. The IRS says you can direct deposit a federal refund into one, two or three accounts using tax software, or Form 8888 if you file on paper. This lets you send part of your refund directly to your emergency savings account.
Should I keep my emergency fund in investments like stocks?
The FDIC says stocks, bonds and mutual funds are not covered by FDIC insurance. The CFPB and Investor.gov both point to bank or credit union savings accounts for money you may need quickly. Investor.gov mentions high-yield savings accounts as one option for that money.
What should I do after I use my emergency fund?
Rebuild it. The CFPB suggests making a plan to replenish the fund, and practicing your savings habits makes this easier over time. Restarting or increasing an automatic transfer is one way to do this.
