How big should an emergency fund be?
The standard advice is 3–6 months of essential expenses. Three months suits stable dual-income households; six is the common default; 9–12 months makes sense for freelancers, single-income families, commission-based earners, or volatile industries. The right number is the one that lets you sleep during a job loss.
What counts as "essential expenses"?
What you would still have to pay if income stopped: housing, utilities, groceries, insurance, transport, minimum debt payments, and essential childcare or medical costs. Not restaurants, subscriptions, or travel — in a real emergency those pause. This usually lands at 60–75% of normal monthly spending.
Where should I keep an emergency fund?
Somewhere instantly accessible and boring: a high-yield savings account, ideally at a separate bank from your spending account so it is out of sight. Not stocks (they may be down exactly when you need the money), not CDs with penalties, not mixed into checking where it will quietly erode.
Should I build the fund before paying off debt?
A common approach: first build a small starter fund ($1,000–2,000) so surprises do not create new debt, then attack high-interest debt hard, then build the full 3–6 month fund. High-interest credit card debt usually outranks a full emergency fund, since the card itself is (expensive) emergency liquidity in the interim.
Should the target be based on my income or my expenses?
Expenses, and specifically essential ones. Income-based targets overstate the fund for anyone who saves a meaningful share of their pay, because the money you were investing is not money you must replace to keep the lights on. The point of the fund is to cover the months where income stops, and what has to keep being paid in those months is rent or mortgage, food, utilities, insurance and minimum debt payments — not your usual spending. Sizing on essentials makes the target smaller and reachable.
Does keeping this much in cash lose money to inflation?
Yes, in real terms, and that is the cost of the insurance rather than a flaw in the plan. Cash held at a rate below inflation loses a little purchasing power each year. What it buys is the ability to absorb a job loss or a broken boiler without selling investments at a bad moment or borrowing at credit-card rates — either of which typically costs far more than the inflation drag. Keep it in the highest-yield instant-access account you can find, and stop at your target rather than over-funding it.
