How Much Should You Keep in an Emergency Fund in 2026?

A common rule is three to six months of essential expenses in cash. For where to hold it, the four online savings accounts below printed APYs between 3.2% and 3.50% on October 23 to 25, 2026, and the FDIC's national savings deposit rate was 0.38% on October 19, 2026. This table covers four online banks, not every provider.

Financeradar data: Figures read between August 11 and October 22, 2026 put our catalog average at 3.21% APY across 50 high-yield savings accounts with a published rate, and all 52 accounts we track state FDIC insurance on their own pages (high-yield savings statistics, computed October 25, 2026).

What the three to six months covers

The three to six month range is a common rule of thumb, not a figure set by a regulator. The rule counts essential expenses, not total spending. Rent or mortgage, utilities, groceries, insurance premiums, transportation, minimum debt payments and childcare usually make the list. Dining out, streaming and vacation savings usually stay off it.

The Consumer Financial Protection Bureau's guide to building an emergency fund says the amount you need "depends on your situation." It suggests starting from the unexpected costs you have already had and what they cost (CFPB, An essential guide to building an emergency fund, last modified October 29, 2025). That is why the examples below use different totals.

One way to size the fund is to weigh two questions: how long a job search might take, and how many people depend on the income. On that basis, one income with a dependent usually lands nearer the top of the range, while two steady earners can often sit nearer the bottom.

Three worked examples

The households below are invented for the arithmetic. They are examples, not survey results or a description of anyone's budget.

The freelancer row fits a household whose pay arrives unevenly, where the six-month figure covers the stretch of slow months. The single renter's six-month figure earns about $504 over a year at the 3.50% APY Marcus printed on October 25, 2026, if that rate held for the full year. At 3.20%, the same balance would earn about $461. The rates are variable, so those numbers are arithmetic on one day's printed APY, not a forecast.

Saving toward the target takes time. For the single renter's six-month target, saving $400 a month takes 36 months, and saving $600 a month takes 24 months. Those counts ignore interest, which would shorten the time slightly.

Four online savings accounts, dated

Each row gives the APY date that the bank prints beside its rate. Rates are variable and can change after the account opens, so the printed date is the only fixed reference in the table.

Ally fits savers who want one online bank with no monthly fee and few outgoing moves. Its page counts online and mobile banking transfers toward the 10-per-cycle limit, so a fund that gets tapped for small bills reaches the limit sooner than one left alone.

Marcus fits savers whose emergency fund stays under $1,000,000 in one Online Savings Account and who want the highest of the four printed rates. Marcus's FAQ also caps one owner at $3,000,000 across all deposit accounts.

Capital One fits savers who can withdraw online or at a branch and do not need ATM access. Its page also says a Capital One or Discover Bank deposit account opened on or after May 18, 2025 counts with other Capital One deposits for FDIC coverage, so a newer Discover account and a Capital One account share one limit.

American Express fits savers who want no minimum and can start transfers before 7:00 PM Eastern Time on a business day. Its account page also notes that deposits may be subject to holds.

For scale, the FDIC's national savings deposit rate was 0.38% as of October 19, 2026 (FDIC national rates and rate caps). Each printed APY in the table is more than eight times that average.

Insurance: the per-depositor limit

The FDIC's deposit insurance page says it covers $250,000 per depositor, per FDIC-insured bank, for each account ownership category (FDIC deposit insurance, last updated April 1, 2024). Checking and savings at one bank in one ownership category share a single limit. An account at a second insured bank gets its own limit, which is why two banks can cover a balance one bank cannot.

All three worked examples sit under the limit at one bank. The couple's six-month target of $33,600 is about 13% of that limit, so one bank can hold the whole fund for those households. A balance above the limit needs a second bank, or a different ownership category such as a joint account, and each of those has its own cap.

The insurance covers the deposit if a bank fails. It does not lock the APY, and none of the four pages promises a rate for the life of the account.

How common a cash cushion is

The Federal Reserve's 2025 household survey found that 63% of adults would cover a $400 emergency expense with cash or its equivalent, unchanged from 2024 (Federal Reserve press release, May 13, 2026). The same report says 55% of adults had set aside money for three months of expenses, unchanged from 2024 but down from a high of 59% in 2021 (Federal Reserve, savings chapter of the 2025 report). Those are survey shares. They describe the population, not a target for any one household. The survey asks what adults would do, so it measures readiness, not how long a cushion would last.

Where to go next

The account list with more products is in the high-yield savings guide and the savings accounts ranking. Product pages for the four accounts above are Ally Online Savings, Marcus Online Savings, Capital One 360 Performance Savings and American Express High Yield Savings. The checking vs savings account comparison covers where the two account types differ, and how much interest a high-yield savings account earns shows the dollar math at other balances. Money-market accounts are a separate product, covered in money market account vs money market fund. Money beyond the emergency fund is a different job, covered in cheapest S&P 500 index funds.

Bottom line

The three to six month range is a common rule, and the dollar target is your essential monthly costs times the months you pick. For the cash itself, the four accounts above fit different savers. Ally fits a low-fee online bank that accepts a 10-withdrawal limit. Marcus fits savers who want the highest of the four printed rates on October 25, 2026, under its $1,000,000 cap. Capital One fits savers who want branch access and do not need an ATM. American Express fits savers who want no minimum and can plan transfers before the evening cutoff.

FAQ

How much should I keep in an emergency fund?

A common rule is three to six months of essential expenses. The CFPB's guide says the amount depends on your situation, so the three examples on this page use different totals (CFPB guide, last modified October 29, 2025).

Is a high-yield savings account a good place for the fund?

It fits savers who want cash they can reach on short notice at an FDIC-insured bank. The four accounts in the table printed their rates on October 23 to 25, 2026. The rate is variable, and the FDIC insurance covers the deposit, not the rate.

Does the $250,000 limit apply per account or per bank?

Per depositor, per insured bank, per ownership category. Checking and savings at one bank in one category share one limit, and a second bank gets its own.

Are the APYs guaranteed?

No. Ally's page says its rates are variable and may change after the account is open, and Capital One's page says advertised rates are subject to change before or after account opening.

What counts as an essential expense?

Costs you would still pay in a bad month: housing, utilities, food at home, insurance premiums, transportation to work, minimum debt payments and childcare. Discretionary spending such as dining out and subscriptions is left out of the monthly figure, so each example uses only the bills that keep running.

How much would a balance earn at these rates?

At the 3.50% APY Marcus printed on October 25, 2026, $14,400 earns about $504 over a year if the rate held. At 3.20%, the same balance earns about $461. That is arithmetic on printed rates, not a projection.
