Your emergency fund is the shock-absorber for life. Use the calculator to size your fund, see how long it’ll take to build, and learn the smart order of operations so you know exactly when to move from saving to investing.
High-Yield Savings or Short T-Bills
Keep emergency money liquid and backed by FDIC/Treasury. Aim for a solid rate with no lockups.

Cash first, then invest
- 3–6 months of essential expenses is a common baseline.

We start from a 3–6 month baseline, then nudge up/down based on your selections.
Why funding your EF first keeps you invested longer
A small Emergency Fund prevents panic selling during dips. This chart contrasts two investors: one with no EF (forced selling), one with a funded EF (stays invested).

Build your EF in 90 days (step-by-step)
Phase 1: Week 1–2
- Open a High-Yield Savings and nickname it “Emergency Fund.”
- Set an auto-transfer for the day after payday.
- Sell clutter; route windfalls (tax refund, bonus) to EF.
Phase 2: Week 3–6
- Cut 2–3 non-essentials temporarily; add side income if possible.
- Build a short T-Bill ladder for part of EF.
Phase 3: Week 7–12
- Re-check your recommended months in the calculator above.
- When target is hit, shift the auto-transfer to investing (ETF basics).

Where to keep an emergency fund?
High-Yield Savings (HYSA)
FDIC-insured up to applicable limits, daily liquidity, and rates that track short-term markets. Great default. (FDIC basics)
Short T-Bills (4–26 weeks)
Backed by the U.S. Treasury; set a simple ladder. Buy via brokerage or TreasuryDirect.
Money Market Funds
Convenient inside brokerages; check expense ratio, holdings, and settlement features.
Set your monthly auto-transfer, then revisit once a year or after major life changes.

FAQs
Is 3–6 months always right?
No. Use ~3 months for stable dual incomes and strong insurance; 6–12+ months if income is variable, you have dependents, or work in a niche job market.
Should any emergency fund be invested in stocks?
Generally no—equity volatility risks forced selling during emergencies. Keep EF safe and liquid; invest surplus in diversified ETFs.
HYSA vs. Money Market Fund vs. T-Bills?
HYSA = simplicity + FDIC. T-Bills = treasury-backed with short ladders. Money market = brokerage convenience; check expense ratios.
What if I have high-interest debt?
Keep a small starter EF ($1k–$2.5k) while attacking >8–9% debt, then finish the EF and shift to investing.
What if I’m also building retirement?
Capture your employer match while funding the EF; after the EF is set, increase contributions to IRA/401(k) and taxable investing.
