How many months do you actually need?
Match the cushion to how fragile your income is. 3 months suits dual-income households with stable jobs; 6 months is the standard for most single earners; 12 months fits freelancers, commission earners, single-income families, and anyone in a niche field where job hunts run long. Base it on essential expenses — rent, food, utilities, insurance, minimum debt payments — not your full lifestyle burn, which typically shrinks the target by 25-40%.
Where to keep it
A high-yield savings account at an online bank — earning 4%+ as of 2026 versus roughly 0.01% at big brick-and-mortar banks. It should be liquid within a day or two, FDIC-insured, and slightly inconvenient to spend (a separate bank from your checking works wonders). Not stocks — a layoff and a market crash arrive together often enough that 2008 and 2020 both proved the point. On $20,000, the high-yield difference alone is ~$800/year for zero extra risk.
Building it without misery
Automate a transfer on payday — savings that require monthly willpower fail. Start with a $1,000 starter fund if you carry high-interest debt, then split extra money between debt payoff and the fund until you reach one month of expenses, then finish the fund. Windfalls (tax refunds average ~$3,000, bonuses, side-gig income) are the fast-forward button: one refund can fund a month or two of cover instantly.
How to use this calculator
Add up your genuinely essential monthly costs — housing, utilities, groceries, insurance, transportation, and minimum debt payments — and enter that figure, not your full lifestyle spending. Choose a coverage target (3, 6, or 12 months) that matches how stable and replaceable your income is, then enter what you've already saved and what you can add monthly. The calculator shows your target, your current progress, and the date you'll reach full funding. If that date feels far off, remember windfalls are the fast-forward button: routing a tax refund or bonus straight to the fund can add a month or two of cover in a single deposit, without touching your monthly budget.
