The buffer that turns a crisis into an inconvenience.
Before investing, before optimizing — a real cushion of cash. Punch in your monthly essentials and what you can save; the calculator shows your target, where you are now, and roughly when you'll cross the finish line.
Estimates only. Monthly compounding at the APY you enter; assumes the rate holds steady (real APYs change). "Essentials" excludes discretionary spending — the point is what survival costs if income stops, not your full lifestyle. Park the fund in a high-yield savings account, not investments.
Three tiers, depending on your life stage.
The right number isn't fixed — it scales with how stable your income is and how many people depend on it. Start at the smallest milestone and climb. Each tier buys you a different kind of calm.
- $1,000 starter. Stops a flat tire, a copay, or a phone screen from becoming credit-card debt. Aim for this in months, not years.
- 1 month of essentials. Covers a missed paycheck, a slow freelance month, or a job change with a brief gap. The first real safety net.
- 3 months of essentials. The default for most stable W-2 jobs. Enough to absorb a layoff while you take a careful — not desperate — job search.
- 6 months of essentials. For variable income, single-earner households, or specialized roles with longer hiring cycles. Also a good ceiling once you're investing aggressively.
"Essentials" means what survival costs if income stops — rent, groceries, utilities, insurance, minimum debt payments. Not concerts, not subscriptions, not new clothes.
Liquid and boring is the whole point.
An emergency fund's job is to be there on the worst day of the year, not to grow. The right home is a high-yield savings account at an FDIC-insured bank. Don't park it in stocks — emergencies have a habit of arriving on the same day the market drops 20%.
- High-yield savings (HYSA). Currently ~4–5% APY at most online banks. Liquid in 1–2 business days. The default answer.
- Money market account. Similar APY, sometimes with check-writing. Fine alternative — same tier of safety.
- Checking account. Only the first $500–1,000 lives here for instant access. The rest earns more in HYSA.
- Not for the emergency fund: brokerage accounts, crypto, CDs longer than 3 months, anything that could be down the day you need it.
Where the fund fits in the full sequence.
Building this isn't all-or-nothing. Most people layer: hit the $1,000 starter first, then capture any 401(k) match (it's free money you can't replace), then finish the 3–6 month cushion, then open a Roth IRA. Skipping the match while you build the fund leaves real dollars on the table.
- Step 1. Save $1,000 starter — fast, even if it means temporarily pausing other goals.
- Step 2. Capture the full 401(k) employer match — see the employer-match calculator for what skipping it costs.
- Step 3. Finish the 3–6 month emergency fund.
- Step 4. Open a Roth IRA and contribute up to the annual limit.
- Step 5. Increase 401(k) contributions beyond the match.
Where this estimate is rough.
- APY drifts. Savings rates move with the Fed. The number you enter is today's rate, not a 5-year guarantee.
- Essentials change. A move, a kid, a new car payment — re-run this whenever your fixed costs shift.
- "Emergency" is narrow. A vacation isn't an emergency. A new couch isn't an emergency. Replenish the fund every time you actually use it.
- Healthcare is a wildcard. A high-deductible health plan with a pending deductible may justify a slightly bigger fund — or a separate HSA buffer.
