An emergency fund target depends on essential monthly expenses, income uncertainty, and the surprises a household could face. One common approach starts with a small buffer, builds toward a chosen number of months of essentials, and keeps the money in an accessible, insured deposit account.
What the surprise-expense survey shows
In the Federal Reserve's household survey for 2025, 63% of adults said they would cover a hypothetical $400 expense exclusively with cash, savings, or a credit card paid off at the next statement. The Fed calls these methods "cash or its equivalent."
Another finding was that 12% of all adults said they would be unable to pay the $400 expense by any means. Most adults outside the cash-or-equivalent group would still pay another way, such as carrying a card balance or borrowing from family or friends. Federal Reserve savings and investments report
The distinction matters: a question about how people would pay does not establish that everyone choosing another method lacks savings.
Why there is no universal target
The CFPB emergency-fund guide explains that the amount depends on the household's situation. Past unexpected expenses and their costs provide context for a starting goal.
Factors to weigh include variable earnings, dependents, reliance on a sole earner, likely job-search time, insurance deductibles, and essential transportation. A repair bill and an extended income interruption create different demands on a reserve.

A starter goal can be smaller
The CFPB's savings booklet states: "The target amount for emergencies depends on your needs. Consider starting with $500 as your goal." CFPB savings booklet
That is a suggested starting point, rather than a promise that every emergency will fit within it. A small buffer can absorb part of a surprise while a larger reserve develops.
The CFPB also describes automatic transfers, splitting direct deposit, and saving part of an occasional payment as possible ways to build savings. Their practicality depends on money available after bills. Using a reserve for an emergency fulfills its purpose; rebuilding it depends on the household's subsequent cash flow.
