An emergency fund is money set aside strictly for the unplanned: a job loss, a medical bill, a car repair, a broken furnace. It is not a savings goal for something you're looking forward to — it's the buffer that keeps a bad month from becoming bad debt.
How big should it be?
The common rule of thumb is three to six months of essential expenses — rent or mortgage, utilities, groceries, insurance, minimum debt payments. Where you land in that range depends on how stable your income is:
- More stable income (salaried, dual-income household, low layoff risk): three months is often enough.
- Less stable income (commission-based, single income, contractor, high layoff risk in your industry): lean toward six months or more.
The number is essential expenses, not your full current spending — an emergency fund is there to keep the lights on, not to maintain your normal lifestyle indefinitely.
Where to keep it
An emergency fund needs to be:
- Liquid — available within a day or two, no penalty for withdrawing.
- Stable — not exposed to market swings, since you may need it exactly when markets are down.
- Separate — in its own account, so it doesn't quietly get spent as part of everyday checking-account balance.
A high-yield savings account is the usual answer: FDIC-insured, no market risk, and it pays some interest while it waits. It should not be invested in stocks or funds — the point of this money is that it's there when everything else is going wrong, not that it grows the fastest.
Building it
If three to six months feels out of reach right now, that's normal — treat it as a target to grow toward, not a bar you need to clear before doing anything else. A starter goal of one month of essential expenses closes off the most common source of new debt: a single unexpected bill turning into a credit card balance. Build from there.
