Emergency Fund: Why Three Months of Bills Is a Good Target
Short answer
Start with a first goal of $500 to $1,000, then build to three months of your essential bills: rent, utilities, insurance, transportation and minimum debt payments. Save automatically from every paycheck into a separate account at an FDIC- or NCUA-insured bank or credit union, and use it only for real emergencies.
An emergency fund is money set aside for the things you can’t plan: a car repair, a medical bill, a week without pay. The hard part is choosing a target. A practical answer is to base it on your bills. Three months of essential bills means your home keeps running even if your income stops for a while.
Start with a first goal
A big target can feel out of reach, so start small. Washington State’s Department of Financial Institutions suggests setting “a first goal of $500 to $1,000,” which it says covers many common emergencies, such as a vehicle repair.
Hitting that first goal changes how an emergency feels: a surprise bill becomes an inconvenience instead of a crisis.
Then build to three months of bills
Washington DFI notes that many experts suggest saving 3 to 6 months of basic living costs, such as housing, utilities, food and transportation. Three months of your essential bills is a practical first version of that.
Work out one month of essential bills
List the bills you’d keep paying even in a hard month. A worked example, with made-up amounts:
| Essential bill | Monthly |
|---|---|
| Rent | $1,350 |
| Electric, gas and water | $200 |
| Phone and internet | $120 |
| Car insurance ($1,080 ÷ 12) | $90 |
| Car payment | $320 |
| Minimum debt payments | $100 |
| One month of essential bills | $2,180 |
Your full target is three times that: $6,540 in this example. Use your own numbers, and leave out spending you could cut quickly, like streaming.
Build it automatically
Saving works best when it happens before you can spend the money. Washington DFI recommends setting up a recurring transfer from each paycheck and notes that “even $10 to $25 adds up.”
- Set an automatic transfer for the day after each payday.
- Start with what you can. Raise it when a bill goes down or your pay goes up.
- Add windfalls. Tax refunds, bonuses, and extra paychecks if you’re paid weekly or biweekly. Our guide to weekly pay explains the five-paycheck months.
While you’re building it
Until your fund reaches its first goal, a few habits lower the chance of needing it:
- Know your due dates. A missed payment can bring late fees. Our guide to avoiding late fees covers grace periods and due-date changes.
- Plan for the bills you can see coming, so they don’t become emergencies.
- Call before you miss a payment. Contact the company before the due date and ask what options it has.
Where to keep it
Washington DFI recommends a bank or credit union insured by the FDIC or NCUA, and keeping the fund in its own account, apart from everyday checking, so you’re less likely to spend it.
At an FDIC-insured bank, the FDIC says deposit insurance covers $250,000 per depositor, per bank, for each account ownership category, and savings accounts are covered.
Keep it easy to reach. An emergency fund needs to be available within a day or two.
Emergencies vs. bills you can see coming
The fund works best when it’s only for emergencies. Bills you know about, like car registration or a yearly insurance premium, are better covered by saving a little each month in a separate pot. Our guide to annual and irregular bills shows the sinking-fund method.
If you use it, rebuild it
When you take money out for an emergency, restart your automatic transfer right away, even at a lower amount. The fund only helps if it’s there next time.
An emergency fund also protects against fees
A cushion helps with everyday bills too. The CFPB warns that if your balance is too low when an automatic payment is due, both the bank and the company might charge a fee. Even a small emergency fund in a linked account can keep one late paycheck from turning into a string of fees.
Keep your target current
Your target moves when rent, insurance or other bills change. A bill tracker like Billo keeps all your bills in one list and shows what’s due before payday and what’s left after bills, which makes it easy to recalculate your three-month number and see how much you can save.
Summary
- First goal: $500 to $1,000.
- Full target: three months of essential bills.
- Save automatically from every paycheck.
- Keep it separate, insured and easy to reach.
