A HYSA holds your money in a bank account and pays you interest at a rate that changes with the market

A high-yield savings account is a regular savings account offered by a bank or credit union, but with one key difference: the interest rate is much higher than what you get at most traditional banks. When you deposit money, the bank pays you interest on that balance. The rate fluctuates based on what the Federal Reserve does with its benchmark rate — when the Fed raises rates, HYSAs typically raise theirs too. When the Fed cuts rates, HYSA rates fall.

The money stays yours at all times. You can withdraw it whenever you want, usually within one or two business days. There is no lock-in period, no penalty for taking your money out early, and no minimum balance requirement at most providers. The tradeoff is that the interest rate is not may provide to stay the same — it can go down, and it will, if the Fed lowers rates.

HYSAs are offered by online banks (like Marcus, Ally, or American Express Bank), some credit unions, and a few brick-and-mortar banks. They are FDIC-insured up to $250,000 per account holder per bank, which means if the bank fails, your money is protected by the federal government.

Key Takeaways

  • You earn interest on the money you deposit, and that rate changes when the Federal Reserve changes its benchmark rate.
  • You can withdraw your money anytime without penalty, and it usually arrives in your account within one or two business days.
  • Your deposits are protected up to $250,000 by FDIC insurance, so your money is safe even if the bank fails.
  • The interest rate is not locked in — it can drop if the Fed lowers rates or if the bank decides to reduce its rate.
  • You pay no monthly fees at most HYSA providers, though some charge a fee if your balance falls below a certain amount.

How interest is calculated and paid to you

Interest on a HYSA is calculated daily based on your account balance and the annual percentage yield (APY). The APY tells you what percentage of your balance you will earn in a year if the rate stays the same. For example, if you have $10,000 in an account with a 4.50% APY, you will earn roughly $450 over the course of a year — though the actual amount depends on how often interest is compounded and paid out.

Most HYSAs compound interest daily, which means the bank calculates interest on your balance each day, and then adds that interest to your account. Some banks pay interest monthly, others weekly. The more often interest is compounded, the slightly more you earn, because you earn interest on the interest that was already added.

You do not have to do anything to receive the interest — it is deposited automatically into your account on the schedule the bank sets. You can then withdraw it, leave it to earn more interest, or transfer it to another account.

Why rates change and how to track them

HYSA rates move because banks compete for deposits and because the Federal Reserve sets a benchmark rate that influences what banks pay. When the Fed raises its benchmark rate, banks typically raise HYSA rates to attract more customers. When the Fed cuts rates, banks lower HYSA rates — sometimes quickly, sometimes over several weeks.

The rate you see advertised today may not be the rate you earn next month. Banks are required to notify you before they lower your rate, usually by email or through your online account. You can then decide whether to move your money to a bank offering a higher rate, or stay put.

To track current HYSA rates, you can visit comparison websites like Bankrate, DepositAccounts, or NerdWallet, which update rates daily. You can also check the websites of individual banks directly. Rates vary widely — at any given time, the highest-paying accounts may offer 1% or more than the lowest-paying ones.

Deposits, withdrawals, and how long transfers take

Depositing money into a HYSA is straightforward. You can transfer money from another bank account you own using the HYSA provider's website or app. You provide your other bank's routing number and account number, and the transfer usually takes one to two business days. Some banks offer faster transfers for an extra fee, or instant transfers if you link a debit card.

You can also deposit money by mailing a check, using direct deposit from your employer, or transferring money from a mobile payment app like Venmo or PayPal, depending on what the bank offers. Some online banks do not accept checks by mail, so check the bank's deposit methods before you open an account.

Withdrawals work the same way in reverse. You request a transfer to another bank account, and the money arrives in one to two business days. You can also withdraw cash by transferring to a linked debit card account, though some banks charge a fee for this. There is no limit on how many times you can withdraw per month — that rule was eliminated in 2020.

Fees and what to watch for

Most online banks that offer HYSAs charge no monthly maintenance fee, no overdraft fees, and no fees for transfers or withdrawals. However, some banks do charge fees in specific situations. A few charge a fee if your balance drops below a certain minimum (often $25,000 or $100,000). Some charge a fee if you make more than a certain number of transfers per month, though this is rare.

Read the fee schedule before you open an account. The bank is required to provide this information, usually in a document called the "Deposit Account Agreement" or "Schedule of Fees." If a bank advertises no fees but charges them under certain conditions, that is still a fee — just a conditional one.

You will also owe income tax on the interest you earn. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you must report that on your tax return. This is true even if the interest is small.

HYSA versus money market accounts and regular savings accounts

A money market account is similar to a HYSA but usually requires a higher minimum balance and may offer check-writing privileges. The interest rate is often comparable to a HYSA, sometimes slightly higher, sometimes lower. Money market accounts are also FDIC-insured.

A regular savings account at a traditional bank typically pays much less interest — often 0.01% to 0.05% APY, compared to 4% to 5% at a HYSA. The tradeoff is that traditional banks have physical branches where you can deposit cash or speak to someone in person. If you need to deposit cash regularly, a traditional bank or credit union may be more convenient than an online HYSA.

A certificate of deposit (CD) is different: you agree to leave your money untouched for a set period (three months, one year, five years), and in exchange the bank locks in a higher rate. If you withdraw before the term ends, you pay a penalty. CDs are useful if you know you will not need the money for a specific period, but they are less flexible than a HYSA.

How to choose a HYSA and what to consider

Start by comparing current rates on a rate-tracking website. The highest-paying accounts change frequently, so do not assume the same bank will be the best next month. Look for a bank that offers a rate at least 4% or higher if possible, though rates vary based on market conditions.

Next, check the deposit methods. If you need to deposit cash, make sure the bank accepts checks or has a way for you to deposit cash. If you only transfer money electronically, this matters less. Look at how long transfers take — most take one to two business days, but some offer faster options.

Read the fee schedule and the account terms. Make sure there are no surprise fees for low balances or frequent transfers. Check whether the bank offers customer support by phone or email, in case you have questions. Finally, confirm that the bank is FDIC-insured — this information is usually displayed prominently on the bank's website.

Frequently Asked Questions

Can I lose money in a HYSA?

No. Your principal — the money you deposit — is protected by FDIC insurance up to $250,000. The interest rate can go down, which means you earn less, but you will not lose the money you put in. The only exception is if you withdraw money and then the rate drops — you will have earned less interest on the smaller balance.

What happens if the bank fails?

The FDIC takes over and protects your deposits up to $250,000 per account holder per bank. You will be able to access your money, though it may take a few days. If you have more than $250,000 at one bank, only the first $250,000 is protected, so some people spread large amounts across multiple banks.

Can I use a HYSA like a checking account?

Most HYSAs do not come with a debit card or checkbook, so you cannot use them for everyday purchases. They are designed for saving, not spending. Some banks offer a linked checking account, but you would need to transfer money to it first. A few money market accounts offer check-writing, but most HYSAs do not.

What if I need my money before the transfer arrives?

Transfers usually take one to two business days. If you need cash immediately, you cannot get it from a HYSA without waiting. This is why many people keep a small emergency fund in a checking account and use a HYSA for money they will not need right away.

Do I have to report HYSA interest on my taxes?

Yes. The bank sends you a 1099-INT form at the end of the year showing the interest you earned, and you must report it as income on your tax return. Even small amounts of interest must be reported. This is true for all savings accounts and investment accounts that earn interest or dividends.
