Funding it without pain

Common questions

How big should an emergency fund be?
The standard ladder: 3 months of essential expenses for dual-income stability, 6 months for single earners and homeowners, 8–12 for freelancers and lumpy income. A 3-month fund is the sensible minimum for dual-income households in stable fields, renters without dependents, and anyone also carrying strong unemployment insurance or family backstop. Below 3 months isn't a fund — it's a buffer.
What counts as 'essential expenses' for an emergency fund?
The survival budget: housing, utilities, groceries, transport to work, insurance, minimum debt payments, and medications. Everything cancellable — subscriptions, eating out, holidays — stays out. The fund covers the lean version of your life, so it lasts longer than you fear.
Where should I keep my emergency fund?
Instant-access high-yield savings or a money-market account — same-day withdrawal, no market risk, no lock-ups. A fund in stocks is a bet, not a buffer: emergencies correlate with downturns, exactly when selling hurts most.
Should I build the fund or pay off debt first?
A $1,000–2,000 starter fund first (so the next surprise doesn't go on the card), then high-APR debt, then the full 3-month fund. Minimum payments on cheap debt can wait; 25% card debt cannot.

How we calculate

What is included

The target is essential monthly expenses × 3. Progress uses your current savings against that target; the timeline divides the gap by your monthly contribution. No interest on the fund is assumed — conservative, and closer to how people actually fund these.

What is estimated or left out

Interest earned in a high-yield account would shorten the timeline slightly; inflation would lengthen it. The page assumes your essentials estimate is the lean budget — if you entered your full lifestyle spend, the target is overstated and you'll quit before funding it.

The formula, in plain words
target = monthly essentials × 3 gap = target − saved months = gap ÷ monthly contribution
