How many months do you actually need?
The classic advice is three to six months of essential expenses. The right number tracks your income risk: a dual-income household of civil servants can hold less; a single-income freelancer in a cyclical industry should hold more. Two questions cut through it: how long would a realistic job search take? and how many people depend on this income?
Essential expenses, not total spending
Fund the survival version of your life, not the current version: housing, utilities, groceries, insurance, transport, minimum debt payments. Most households find essentials are 60–75% of normal spending. Using total spending inflates the target and delays the moment the fund actually protects you.
Where to keep it
- High-yield savings account — the default answer: instant access, deposit-insured, currently earning meaningful interest.
- Not the stock market — the one guarantee about emergencies is bad timing; a 30% drawdown the month you lose your job defeats the purpose.
- Not your checking account — visible money gets spent. A separate account at a separate bank adds useful friction.
Building it without stalling other goals
A practical sequence: save a starter $1,000–$2,000 first (covers most single emergencies), then split spare cash between high-interest debt and the fund until you hit one month of expenses, then grind to the full target. Windfalls — tax refunds, bonuses, side income — are emergency-fund rocket fuel precisely because they were never in the monthly budget.
