Just 46% of Americans Have Three Months of Emergency Savings. For a Retiree, Three Months Is the Wrong Number

Standard advice on emergency savings says to keep three to six months of expenses in cash, a rule designed for people who get a salary. A working household’s main risk is losing that salary, and three months is about how long a job search might take. Most Americans don’t meet even that bar.

In the FINRA Foundation’s National Financial Capability Study, 2024 wave, 46% of respondents said they had set aside rainy day funds covering three months of expenses. That share fell six percentage points from 2021, ending a steady rise that had run since 2009.

Older Americans Lead on Savings but Face Different Risks

To be clear, FINRA data vary by age, and among adults 55 and older, 59% have three months set aside. For those 18 to 34, it’s 36%, but results also vary by income. The figure is 22% for households making under $25,000 and 66% for those making $75,000 or more.

Older savers look better prepared on this measure, but the measure was built around a working life. Retiree spending shocks tend to come from other places: a new roof, a medical bill, a replacement car, or helping an adult child. A falling stock market can be another. If a retiree has to sell stocks to pay the bills during a downturn, those losses become permanent. Less remains to recover when prices return.

What One to Two Years of Cash Looks Like for a Retiree

A common planning approach handles this by keeping one to two years of spending needs in cash or safe short-term holdings. That means the spending left over after guaranteed income such as Social Security or a pension, and it’s a widely used framework rather than a fixed rule, with the right amount depending on the household.

Here’s how it works for a hypothetical retiree who spends $4,500 a month and gets a $500 pension. Social Security’s estimated average benefit for all retired workers is $2,071 a month after the 2026 adjustment. That leaves a monthly gap of $1,929 to be paid from savings.

One year of that gap is $23,148, and two years is $46,296. Under the traditional rule, three months of this retiree’s full spending would be $13,500. The retiree-style buffer is larger. It’s also tied to the money that must come out of investments, rather than total spending.

Inflation affects the buffer size over time. The Social Security cost-of-living adjustment for 2027 is 3.6%. The Bureau of Labor Statistics’ research price index for Americans 62 and older also rose 3.6% through September 2026, hitting its highest reading on record. That index gives more weight to housing and medical care, which tend to take up a larger share of older households’ budgets.

Medicare Gaps Can Make the Cushion Bigger

Health costs can be difficult to predict. In 2026, the standard Medicare Part B premium is $202.90 a month, and the Part B deductible is $283. A hospital stay causes a separate Part A deductible of $1,736 per benefit period.

Original Medicare has no yearly limit on out-of-pocket costs unless the retiree buys supplemental coverage, according to Medicare.gov. Medicare Advantage plans do set an annual out-of-pocket maximum, which is a key difference between the two options. Original Medicare has no ceiling on these costs. Without a Medigap policy, a retiree on Original Medicare may need a cash reserve to cover a bad year.

Where Retirees Keep Their Cash and What It Earns

Treasury bills are one option. These are short-term government debts that pay back their full face value at maturity. On October 29, 2026, the average yield was 3.99% on 4-week bills, 4.34% on 26-week bills, and 4.46% on 52-week bills. Some retirees set up a ladder, buying bills that mature on different dates so cash comes due as bills come due.

Treasury interest has a tax advantage. According to IRS Publication 550, it’s subject to federal income tax but exempt from all state and local income taxes. That helps most in high-tax states. We covered this in our recent piece, Treasury Bonds Are a Quiet State Tax Shelter for Savers in High-Tax States.

High-yield savings accounts at FDIC-insured banks are protected up to the federal insurance limit for each depositor at each bank. Their rates can change at any time. Money market funds hold short-term securities and are generally easy to access, but they aren’t bank deposits and don’t carry FDIC insurance. Recent coverage shows savings rates still competing for deposits heading into November.

One Account That Gets the Cushion Started

The first piece is a high-yield savings account. In many retirement plans, it sits at an FDIC-insured bank, linked to the checking account that receives Social Security deposits. It covers the next several months of the income gap and can be accessed within a day or two, and Treasury bills or a money market fund can then hold the rest of the one-to-two-year reserve. Rates on all three options change over time.
