Emergency Fund
Cash reserved for genuine surprises — job loss, medical bills, urgent repairs — typically sized at 3–6 months of essential expenses.
An emergency fund is cash held in reserve for genuine surprises — job loss, medical bills, urgent home or car repairs — so that a bad month becomes an inconvenience instead of a debt spiral. The standard sizing is 3 to 6 months of essential expenses: lean toward three with stable income and low fixed costs, toward six or more with variable income, dependents, or a specialized job market.
Two definitional points do most of the work. First, it’s sized on expenses, not income — the stripped-down monthly cost of running your life (housing, food, utilities, insurance, minimum debt payments). Second, it lives in boring, instantly accessible accounts — high-yield savings with FDIC insurance — because its job is liquidity, not growth. Money that might be down 20% in a market crash, or locked behind a CD penalty, isn’t emergency money.
The fund’s real product is behavioral: households with a buffer can decline high-interest debt at exactly the moments lenders profit most. The Federal Reserve’s well-being surveys repeatedly find a large share of adults unable to cover even a $400 surprise in cash — the gap between that and a funded reserve is a monthly plan, which the emergency fund calculator will build from your actual numbers.
