A traditional savings account at a big bank pays you about 0.01% APY. A high-yield savings account (HYSA) pays 4–5%. On a $10,000 emergency fund, that's the difference between earning $1 a year and earning $450. There is no good reason to leave money in a low-rate account.

What is a HYSA?

A high-yield savings account is a regular FDIC-insured savings account, usually offered by online banks that don't pay for branches. Your money is just as safe as at a brick-and-mortar bank — up to $250,000 per depositor, per bank.

Features that actually matter

  • APY (Annual Percentage Yield). The headline number. Currently the best are around 4.25–4.75%.
  • FDIC insurance. Non-negotiable. Always check the bank's name on FDIC.gov.
  • No monthly fees, no minimum balance. If a "high-yield" account charges $5/month, walk away.
  • Easy ACH transfers. 1–3 business day transfers to your checking should be free and unlimited.
  • Mobile check deposit. Useful if you ever receive paper checks.

Marketing fluff to ignore

  • Promotional teaser rates. Some banks offer 6% for 3 months and then drop to 2%. Read the fine print.
  • "Up to" rates that require linked accounts or balance tiers. Look for a single, clean APY.
  • Cute bonuses. A $200 sign-up bonus is nice but irrelevant if the long-term APY is low.

Solid options as of 2026

Always verify rates before opening — they change. As of this writing, well-reviewed HYSAs include:

  • Ally Bank Online Savings
  • Marcus by Goldman Sachs
  • SoFi Checking & Savings (rate requires direct deposit)
  • Discover Online Savings
  • Capital One 360 Performance Savings

HYSA vs. money market vs. CD vs. T-bill

  • HYSA: liquid, variable rate, FDIC insured.
  • Money market: similar to HYSA, sometimes with check-writing.
  • CD (Certificate of Deposit): locks money for a term (3, 6, 12 months) at a fixed rate. Penalty for early withdrawal.
  • Treasury bills: short-term U.S. government debt, exempt from state income tax. Buy through TreasuryDirect or a brokerage.

How to use a HYSA

Best uses: emergency fund (3–6 months of expenses), short-term savings goals (vacation, car down payment, wedding), and a place to park cash you might need within 1–2 years. For longer-term goals, look at investing instead.

The bottom line

Switching from a 0.01% account to a 4.5% account takes about 15 minutes and earns you free money for the rest of your life. There's no excuse.
