The best rate depends on what you're saving and how much you have

There is no single "best" bank because interest rates change weekly, vary by account type, and depend on your balance. A high-yield savings account at an online bank might pay 4.50% APY one month and 4.25% the next. A money market account at a credit union might beat that by 0.10% but require a $10,000 minimum. A traditional bank's savings account might pay 0.01%. You need to know what you're comparing: savings accounts, money market accounts, certificates of deposit (CDs), or checking accounts.

The rate you actually receive also depends on your balance size. Some banks offer their highest rate only on balances above $100,000. Others tier their rates—you might earn 4.00% on the first $25,000 and 3.50% on anything above that. A few banks pay the same rate on all balances. Before you move money, check whether the rate applies to your balance amount.

Key Takeaways

  • Online banks and credit unions typically offer higher rates than traditional brick-and-mortar banks because they have lower overhead costs.
  • Interest rates change frequently—sometimes weekly—so the highest rate today may not be the highest rate next month.
  • You need to compare the same account type across institutions: high-yield savings to high-yield savings, not savings to money market.
  • Check whether the rate you see applies to your balance size, because many banks offer different rates for different balance tiers.
  • FDIC insurance covers up to $250,000 per depositor per bank, so splitting money across multiple banks protects larger amounts.

Where to find current rates for different account types

High-yield savings accounts are the most common place people look for rate comparisons. Online banks like Marcus, Ally, American Express Personal Savings, and Discover typically offer rates between 4.00% and 4.75% APY, though this changes. Credit unions often match or beat these rates. Traditional banks—Chase, Bank of America, Wells Fargo—usually pay under 0.50% on savings accounts.

Money market accounts function like savings accounts but may require higher minimum balances and offer slightly different rates. Some pay more than high-yield savings; others pay less. You have to check each institution separately.

Certificates of deposit (CDs) lock your money away for a set term—3 months, 6 months, 1 year, 5 years—in exchange for a may provide rate. Longer terms usually pay more. A 1-year CD might pay 4.50%, while a 5-year CD might pay 4.75%. If you withdraw early, you pay a penalty. Online banks and credit unions typically offer higher CD rates than traditional banks.

Checking accounts rarely pay meaningful interest. A few online banks and credit unions offer checking accounts with rates between 2.00% and 5.00%, but these usually require direct deposit, a minimum number of debit card transactions per month, or a high balance. Read the fine print carefully.

How to compare rates across banks

Use a rate comparison site like Bankrate, DepositAccounts, or DepositRate to see current rates across multiple banks at once. These sites update daily or weekly and let you filter by account type, minimum balance, and whether you want FDIC insurance. The rates shown are accurate as of the date listed, but they change frequently.

After you find a few options, visit each bank's website directly to confirm the rate and check the terms. Some banks advertise a promotional rate for new customers only—after 3 or 6 months, the rate drops. Others have no promotional period and pay the same rate to all customers. The website should state this clearly.

Call the bank if the website is unclear. Ask: What is the current APY? Does it apply to my balance size? Is this a promotional rate, and if so, for how long? What happens after the promotional period ends? Are there monthly fees? Is there a minimum balance requirement?

Why online banks and credit unions usually pay more

Online banks have no physical branches, so they spend less on rent, staff, and overhead. They pass some of that savings to customers in the form of higher interest rates. They also tend to have lower loan loss rates because they can be more selective about who they lend to. Ally, Marcus, and American Express Personal Savings are examples of online banks that consistently rank high on rate comparison sites.

Credit unions are member-owned cooperatives, not shareholder-owned corporations. They exist to serve their members, not to maximize profit. Many credit unions pay rates as high as or higher than online banks. However, you must be a member to open an account, and membership requirements vary. Some credit unions are open to anyone in a geographic area; others require you to work for a specific employer or belong to a specific organization.

Traditional banks pay lower rates because they have higher costs and because they rely on brand recognition and branch convenience to attract deposits. They do not need to compete on rate alone.

What happens when rates drop

When the Federal Reserve lowers interest rates, banks lower the rates they pay on savings accounts within days or weeks. Your rate will not stay at 4.50% forever. If you lock money into a CD, your rate is may provide for the term. If you keep money in a savings account, the rate can drop at any time, and the bank will notify you by email or mail before the change takes effect.

This is why some people move money between banks chasing the highest rate. If your current bank drops its rate to 3.50% and another bank is paying 4.25%, you can withdraw your money and move it. There is no penalty for moving money out of a savings account (only out of a CD before the term ends). The process takes 3 to 5 business days via ACH transfer.

FDIC insurance and how it protects your money

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, you get your money back up to that limit. If you have $500,000 and want full coverage, you can split it: $250,000 at Bank A and $250,000 at Bank B. Both are fully insured.

Credit unions are insured by the National Credit Union Administration (NCUA), which works the same way: $250,000 per member per credit union. If you belong to multiple credit unions, each account is insured separately.

Check whether a bank is FDIC-insured before you open an account. The bank's website will state this. If it is not insured and the bank fails, you have no protection.

Frequently Asked Questions

Can I move my money to a higher-rate bank without losing interest?

Yes. When you transfer money out of a savings account, you do not pay a penalty. The transfer takes 3 to 5 business days via ACH. Interest accrues daily and is paid monthly, so you will earn interest up to the day you withdraw. You will not earn interest at the new bank until the money arrives and posts to your account.

What if I withdraw money from a CD early?

You pay an early withdrawal penalty, which the bank deducts from your balance. The penalty varies by bank and CD term—it might be 3 months of interest or 1% of the balance. Check the CD's terms before you open it. If rates rise significantly, the penalty might be worth paying, but calculate it first.

Do I need a minimum balance to get the advertised rate?

Many banks do. Check the account details on the bank's website. If the rate requires a $25,000 minimum and you only have $10,000, you may earn a lower rate or no interest at all. Some banks have no minimum; others tier rates by balance.

How often do banks change their interest rates?

Banks can change rates at any time without notice, though they usually notify customers before the change takes effect. Rates typically move when the Federal Reserve changes its benchmark rate, but banks may also adjust independently. Check your bank's website or rate comparison sites weekly if you want to stay current.

Is a promotional rate worth switching banks for?

Only if the promotional period is long enough to make the move worthwhile. If a bank offers 5.00% for 3 months and then drops to 2.00%, you earn extra interest for 3 months but then earn less than you would elsewhere. Calculate the total interest you will earn during the promotional period and compare it to the hassle of moving money. If it is under $100, it probably is not worth it.
