Emergency funds: how much, and why

An emergency fund is money set aside for genuine emergencies — job loss, a medical bill, an urgent repair — and nothing else. Not a vacation, not an investment opportunity, not a "good deal." Its entire job is to be there, boring and unspent, until the day you actually need it. How much is enough is a range, not a fixed rule: a common starting target is 3 to 6 months of essential expenses (not your full income — just rent, food, utilities, minimum debt payments, the things you can't skip). If your income is unpredictable — freelance work, a founder's income, commission-based pay — leaning toward 6 to 12 months is more honest, since you can't count on the next paycheck landing on schedule. Where you keep it matters as much as how much: a savings account or a liquid fund, something stable and accessible within a day or two — not the stock market, not a mutual fund tied to equities, not anything that could lose 20% of its value in the exact month you need to withdraw it. The point of this money isn't to grow, it's to be there. Growth is what the rest of your savings are for. Why it's worth building before almost anything else: without it, an unexpected expense usually gets paid for with a credit card or a personal loan at a high interest rate, turning a one-time problem into a recurring one. An emergency fund's real return isn't the (small) interest it earns sitting in a savings account — it's every high-interest debt it lets you avoid taking on in the first place.
