How to choose a high-yield savings account.

What an HYSA is

A high-yield savings account (HYSA) is a regular savings account that pays meaningfully more interest than a traditional one. As of 2026, traditional brick-and-mortar bank savings accounts pay 0.01%–0.05%; online HYSAs pay 4%–4.5%. On a $20,000 balance, that’s the difference between $4 and $850 per year of interest — for the same level of access and the same FDIC protection.

The reason online banks can pay more is straightforward: they don’t run physical branches. The savings get passed through to depositors as higher yield.

The rate is the obvious thing

Every comparison site leads with the rate, and rate matters. But the rate banks advertise is a snapshot. Most banks reserve the right to change the rate at any time, with no notice. A bank that’s a market leader in March can be twenty basis points behind the market by November without sending you so much as an email.

The corollary: don’t pick an HYSA and forget about it for five years. Once a year — at the same time you do anything else annual, like the W-4 — pull up the current rate at three or four competitive banks and confirm yours is still in range. If it’s materially behind, moving an HYSA takes about twenty minutes.

What actually matters over time

Beyond the headline rate, the features that matter over years:

• FDIC insurance, in your name. Confirm the bank itself is FDIC-insured (or NCUA-insured if it’s a credit union) and that your deposits are titled in a way that qualifies. Standard coverage is $250,000 per depositor per insured bank.
• No monthly fees, no minimum balance. Either of these on an HYSA in 2026 is a sign you should be at a different bank. The competitive market has eliminated both.
• Transfer speed to your primary checking. Some online banks settle ACH transfers to outside accounts the same day; others take 2–3 business days. For an emergency fund especially, the faster option matters.
• No transfer limits beyond the federal default. Federal Regulation D used to cap savings withdrawals at 6 per month; the cap was suspended in 2020. Some banks still enforce a private version of it. Check.
• Joint-ownership and beneficiary support. If you’re married or want a payable-on-death designation, confirm the bank supports it during account opening, not after.
• A clean web interface and a working app. This sounds trivial. It is not. You will interact with the bank’s software dozens of times a year for the rest of your life.

How to build a shortlist

Three questions to ask a candidate bank, in order:

1. Is the bank or credit union FDIC- or NCUA-insured? (Confirm at fdic.gov or ncua.gov.)
2. What’s the current APY on the savings account, and what’s the bank’s 12-month rate history? (Sites like DepositAccounts publish this.)
3. How long does an outbound ACH transfer to an external bank actually take?

If a bank passes those three, the rest is preference. Open the account, set up a recurring transfer from your checking, and revisit the rate once a year. Our piece on where to keep money you’ll need within a year covers when an HYSA is the right account and when something else (CDs, money-market funds, T-bills) fits better.
