A high-yield savings account pays you more interest than a regular savings account at a bank

A high-yield savings account (HYSA) works like a regular savings account — you deposit money, the bank holds it, and you can withdraw it whenever you need it — except the bank pays you a much higher annual percentage yield (APY) on the balance you keep there. Regular bank savings accounts currently pay between 0.01% and 0.05% APY. High-yield accounts at online banks and credit unions typically pay between 4% and 5.35% APY, though the exact rate changes when the Federal Reserve changes interest rates.

The money you earn is real interest, not a promotional bonus. If you keep $10,000 in an account paying 5% APY for one year, you earn roughly $500 in interest (the exact amount depends on how often the bank compounds interest — usually daily or monthly). That interest gets added to your account balance, and you can withdraw it along with your original deposit at any time.

Key Takeaways

  • High-yield savings accounts pay 4% to 5.35% APY, compared to 0.01% to 0.05% at traditional banks, because online banks have lower overhead costs.
  • Your money is not locked in — you can withdraw the full balance whenever you want, unlike certificates of deposit or money market accounts with withdrawal restrictions.
  • The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, so your money is protected even if the bank fails.
  • Interest compounds daily or monthly depending on the bank, meaning you earn interest on the interest you already earned.
  • The APY rate you see today may drop if the Federal Reserve lowers interest rates, which happens periodically based on economic conditions.

Why online banks pay more than traditional banks

Online banks offer higher APY because they have far lower operating costs than brick-and-mortar banks. They do not maintain physical branches, pay tellers, or cover the rent and utilities of a building in every neighborhood. Instead of passing those savings to shareholders, they pass them to depositors in the form of higher interest rates. This is their main way to attract customers.

Credit unions also often pay higher rates than traditional banks because they are member-owned cooperatives, not profit-driven corporations. They return earnings to members rather than shareholders. However, credit unions typically require you to live or work in a specific area or belong to a particular organization to open an account.

How interest compounds and grows your balance

Interest compounds when the bank adds earned interest to your account balance, and then calculates next period's interest on the larger amount. Most high-yield savings accounts compound interest daily, meaning the bank calculates and adds interest every single day.

Here is how it works in practice: if you have $10,000 in an account paying 5% APY with daily compounding, the bank divides 5% by 365 days to get a daily rate of about 0.0137%. On day one, you earn roughly $1.37. On day two, the bank calculates interest on $10,001.37, so you earn slightly more than $1.37. This continues every day. Over a full year, daily compounding means you earn about $512.68 instead of exactly $500 — the difference comes from earning interest on interest.

Monthly compounding works the same way but happens only 12 times per year instead of 365 times. The difference between daily and monthly compounding is small — usually a few dollars per year on a $10,000 balance — but daily compounding is always better.

What happens when interest rates change

The APY you see advertised is not may provide forever. When the Federal Reserve raises or lowers its benchmark interest rate, banks adjust the rates they pay on savings accounts. These changes usually happen within days or weeks of a Fed announcement.

If rates go up, your APY goes up and you earn more interest. If rates go down, your APY goes down and you earn less. During the period from 2020 to 2023, the Federal Reserve raised rates aggressively, and high-yield savings accounts went from paying 0.5% to over 5%. If the Fed lowers rates in the future, those accounts will pay less. You can move your money to a different bank if rates drop significantly, but there is no penalty for doing so — high-yield savings accounts have no withdrawal restrictions.

FDIC insurance protects your deposit

The Federal Deposit Insurance Corporation (FDIC) insures deposits at member banks up to $250,000 per depositor per bank. This means if the bank fails, the FDIC will return your money up to that limit. This protection covers the principal you deposited plus any interest you earned.

If you have more than $250,000 to save, you can open accounts at multiple FDIC-insured banks and keep $250,000 at each one. Each account is insured separately. Credit unions are insured by the National Credit Union Administration (NCUA) with the same $250,000 limit. Online banks are FDIC-insured just like traditional banks — the lack of a physical location does not affect insurance coverage.

How to move money in and out

Most high-yield savings accounts let you transfer money in and out using ACH transfers (Automated Clearing House), which typically take one to three business days. You can also deposit money by wire transfer, which is faster but may cost a fee. Some online banks let you link your account to an external checking account so you can move money back and forth without visiting a branch.

Withdrawals are not restricted — you can take out your full balance whenever you want. There is no penalty for closing the account or moving your money elsewhere. Some banks offer debit cards linked to the savings account, which lets you withdraw cash at ATMs, though this is less common than it used to be.

Comparing high-yield savings to other places to keep money

A high-yield savings account is different from a certificate of deposit (CD), which locks your money away for a set period (three months to five years) in exchange for a may provide rate. CDs typically pay slightly more than high-yield savings accounts, but you cannot withdraw the money early without paying a penalty. High-yield savings accounts are better if you might need the money soon.

Money market accounts are another option. They work like savings accounts but often require a higher minimum balance and may limit how many times you can withdraw per month. They sometimes pay slightly higher rates than high-yield savings accounts, but the difference is usually small and the restrictions are not worth it for most people.

Regular savings accounts at traditional banks pay so little interest (often under 0.05% APY) that they are only useful if you need to access your money in person or have a relationship with that bank. For money you are not spending right away, a high-yield savings account is almost always the better choice.

Frequently Asked Questions

Can I lose money in a high-yield savings account?

No. Your principal deposit is protected by FDIC or NCUA insurance, and interest only adds to your balance. The only way your balance goes down is if you withdraw money yourself. Interest rates can drop, so you earn less interest than before, but you do not lose what you already earned.

Do I have to pay taxes on the interest I earn?

Yes. Interest earned in a high-yield savings account is taxable income. The bank will send you a Form 1099-INT at the end of the year showing how much interest you earned, and you report that on your tax return. The interest is taxed as ordinary income at your regular tax rate.

What is the minimum balance required to open a high-yield savings account?

Most online banks have no minimum balance requirement — you can open an account with $1 or $0. Some banks require a small opening deposit like $25, but this is rare. Once the account is open, you can keep any balance you want, and some banks pay the same APY whether you have $100 or $100,000.

How often does interest get added to my account?

Interest is calculated daily at most high-yield savings accounts, but it is usually added to your balance monthly. This means you see the interest deposit hit your account once a month, even though the bank was calculating it every day. The timing does not affect how much you earn — daily calculation with monthly deposits still gives you the benefit of daily compounding.

Can I use a high-yield savings account as an emergency fund?

Yes. High-yield savings accounts are ideal for emergency funds because your money is accessible within one to three business days via ACH transfer, and some banks offer ATM cards for faster access. The interest you earn while waiting for an emergency is a bonus. Keep three to six months of expenses in the account so you have a cushion without tying the money up.
