Emergency Funds: The Data on Cash Buffers and Financial Resilience
Federal Reserve survey data shows 63 percent of US adults in 2024 said they could cover a hypothetical $400 emergency expense using cash, savings, or a credit card paid off at the next statement. Bank-account research finds households holding dedicated cash savings fare better than similarly liquid households relying on cutting spending.
The national picture
The Federal Reserve Board's Report on the Economic Well-Being of U.S. Households in 2024, published in 2025 from a survey fielded in October 2024, reports that 63 percent of all adults said they would have covered a hypothetical $400 emergency expense exclusively using cash, savings, or a credit card paid off at the next statement. That figure was unchanged from 2022 and 2023. Thirteen percent of adults said they would be unable to pay a $400 expense by any means, also unchanged from 2022 and 2023 but up from 11 percent in 2021.
Longer-horizon savings
The same report finds that 55 percent of adults said they had rainy-day savings sufficient to cover three months of expenses in 2024, slightly up from 54 percent in 2023 but below the 59 percent recorded in 2021. Sixty-nine percent said they could handle an unexpected expense of at least $500 using only current savings. These are self-reported survey measures, which is worth keeping in mind when comparing them to bank-data studies.
Dedicated savings beat 'I'll just cut back'
Chris Wheat, Daniel M. Sullivan, and Erica Deadman of the JPMorganChase Institute published research in 2025 on cash savings and resilience to unexpected expenses. Among low-income households with similar total liquidity of roughly $1,000, those relying on discretionary spending they could cut showed greater financial distress: nearly 20 percent missed a payment obligation, compared with 7 percent among those holding substantial cash savings. The two groups had comparable resources available. What differed was whether those resources were already set aside.
How thin the typical buffer is
Chris Wheat and George Eckerd's 2023 JPMorganChase Institute analysis of household cash buffers reports that in the period from 2008 to 2019, median cash buffers averaged roughly 13, 16, 19, and 26 days of spending for income quartiles one through four respectively, and that median cash buffers for the bottom income quartile averaged about half those of the top quartile. They also report persistent racial gaps, with Black individuals holding roughly 11 buffer days versus 19 for White individuals from 2009 to 2020, and note mean reversion toward pre-pandemic levels by early 2023 after a pandemic peak.
What this means for budgeting practice
The JPMorganChase Institute finding is the most directly relevant to envelope-style budgeting, and also the one most easily overstated. It compares outcomes for households with similar liquidity but different savings composition; it is observational analysis of account data, not a randomized experiment, so it establishes a strong association rather than proof that moving money into a savings envelope causes fewer missed payments. Read at that level, it still makes a real point: money already designated as savings appears to function differently than money you plan to free up later.

From 2008 to 2019, median cash buffers averaged roughly 13, 16, 19, and 26 days of spending across income quartiles one through four; median buffers for the bottom quartile averaged about half those of the top quartile, and racial gaps persisted (about 11 buffer days for Black individuals versus 19 for White individuals, 2009 to 2020).
Common questions
How many Americans can cover a $400 emergency?
In the Federal Reserve's 2024 survey, 63 percent of adults said they would cover it exclusively using cash, savings, or a credit card paid off at the next statement, unchanged from 2022 and 2023. Thirteen percent said they could not pay it by any means.
Is an emergency fund better than just planning to cut spending?
JPMorganChase Institute research found that among low-income households with roughly $1,000 in total liquidity, nearly 20 percent of those relying on cuttable discretionary spending missed a payment obligation, versus 7 percent of those with substantial cash savings. This is an observational comparison of account data, so it shows a strong association rather than proven causation.
How large is a typical household cash buffer?
For 2008 to 2019, median cash buffers averaged about 13, 16, 19, and 26 days of spending across income quartiles one through four, according to JPMorganChase Institute analysis of account data.
