How many months should you keep?
Three months of essential expenses is the classic floor for someone with a steady paycheck and no one depending on them. Variable income pushes the floor to six months because slow months arrive without warning, and each extra mouth adds time you would need to keep a household running. The tiers land between three and nine months; the goal is a cushion that lets you make decisions from a position of strength, not panic.
Where to keep the money
An emergency fund belongs somewhere safe and boring: a high-yield savings account or money market fund you can reach within a day or two. You are trading some return for certainty, and that is the point. Keep it separate from checking so it is not casually spent, but not locked away where a real emergency turns into a payday loan.

Questions fréquentes
What counts as an essential expense?
Housing, utilities, groceries, insurance, transportation, and minimum debt payments — the bills that keep a household standing. Dining out, subscriptions, and vacations do not make the list, which is why the target is usually smaller than a full month of spending.
Should I save for emergencies or pay off debt first?
Most planners suggest a small starter fund (about one month of essentials) even while tackling high-interest debt, then building toward the full target once the expensive debt is gone. That way a flat tire does not become new credit card debt.
