What Is an Emergency Fund?
An emergency fund is money set aside specifically to cover unplanned expenses or income gaps, kept separate from your everyday spending.
The traditional guidance is 3 to 6 months of essential expenses, but the right number depends on how stable your income is and how much cash flow cushion you actually need. A salaried household with dual income needs less buffer than a commission-based earner with irregular income.
An emergency fund’s job is not to grow. It is to be there. That is why it typically lives in a high-yield savings account, not invested in the market, where it could lose value right when you need to use it.
The fund does not have to be built all at once. Even a small buffer, enough to cover one bad week of timing, removes most of the cost of living paycheck to paycheck.
