Interest rates change weekly, so the highest-paying bank today may not be the highest next month
There is no single answer to which bank pays the most interest, because rates shift constantly and depend on the type of account you open. A bank offering 4.50% on a savings account this week might drop to 4.35% the next week. The bank paying the best rate on a money market account is often different from the one paying best on a certificate of deposit. What matters is knowing where to look and how to check the current rates yourself, rather than relying on a snapshot that will be outdated in days.
The banks offering the highest rates are typically online banks and credit unions, not the large national banks you see on every corner. Online banks have lower overhead costs, which means they can pass higher rates to customers. Credit unions are member-owned and often prioritize competitive rates. Traditional banks like Chase, Bank of America, and Wells Fargo usually offer rates well below what online competitors pay — sometimes by 3% or more on the same account type.
Key Takeaways
- Online banks and credit unions consistently offer higher interest rates than traditional national banks, sometimes by 3% or more on savings accounts.
- Interest rates change weekly or even daily, so you need to check current rates directly rather than relying on articles or comparisons from weeks ago.
- The highest rate for a savings account is different from the highest rate for a money market account or CD, so compare within the account type you want.
- Rate comparison sites like Bankrate, DepositAccounts, and the FDIC's BankFind tool let you filter by account type and see rates updated frequently.
- Moving money to a higher-rate account costs nothing, but confirm the new bank is FDIC-insured before you transfer your funds.
Where online banks and credit unions publish their current rates
Online banks post their rates on their own websites, usually on the savings or deposit account page. You can visit them directly: Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, Discover Bank, and Synchrony Bank are common names in this space, but new banks enter and rates shift constantly. The rate you see on their homepage is the current rate for new deposits, and it applies to your account when ready once you open it.
Credit unions work differently. Your rate depends on which credit union you join, and you must be a member to open an account. Many credit unions are open to anyone in a geographic area or anyone who works in a certain industry. You can search for credit unions near you using the CO-OP Network locator or the Credit Union Locator on the National Credit Union Administration website. Once you find one, call or visit their website to ask about current savings rates.
If you want to compare rates across many banks at once, use Bankrate, DepositAccounts, or the FDIC's BankFind tool. These sites pull rates from multiple banks and update them frequently — though not always in real time. Bankrate and DepositAccounts let you filter by account type (savings, money market, CD) and sort by rate. The FDIC's BankFind is slower to update but shows you which banks are insured and their exact institution names, which matters when you're about to move money.
How to read the rate and understand what it actually means
The number you see — say, 4.50% — is the Annual Percentage Yield, or APY. This is the total interest you earn in a year, including the effect of compounding (interest earning interest). It is always shown as a percentage. The APY is what matters for comparing banks, not the interest rate alone, because APY accounts for how often the bank compounds your interest.
When you see a rate listed, check whether it has any conditions attached. Some banks offer a high rate for the first three months, then drop it. Others offer the high rate only if you set up automatic deposits or keep a minimum balance. Read the fine print on the bank's website or call and ask directly. A 4.50% rate with a $25,000 minimum balance is not the same as a 4.50% rate with no minimum.
Also confirm the account is FDIC-insured if it is a bank, or NCUA-insured if it is a credit union. This insurance protects your money up to $250,000 per account type per institution if the bank fails. Every legitimate online bank and credit union displays this information on their website. If you cannot find it, do not open an account there.
The difference between savings accounts, money market accounts, and CDs
The highest rate for a savings account is not the same as the highest rate for a money market account or a CD, because banks price them differently. A savings account lets you withdraw money anytime without penalty. A money market account is similar but usually requires a higher minimum balance and may offer a slightly higher rate. A CD locks your money for a set term — three months, one year, five years — and pays a higher rate in exchange for that commitment.
If you need access to your money, compare savings account rates. If you have a large lump sum you will not touch for a year or more, a CD might pay 0.25% to 0.50% more. Money market accounts fall in between: they pay more than savings but less than CDs, and you can withdraw money, though some banks limit how many withdrawals you can make per month.
When you use a comparison site, filter by the account type you actually want. Searching for "highest interest rate" without specifying the account type will show you CD rates, which are not useful if you need a savings account.
Why national banks pay less and what that costs you
Chase, Bank of America, Wells Fargo, and Citibank typically pay between 0.01% and 0.50% APY on savings accounts. An online bank might pay 4.00% to 4.75% on the same account. On $10,000, the difference is roughly $400 per year. On $50,000, it is roughly $2,000 per year. The gap exists because national banks have thousands of branches, millions of customers, and high operating costs. They do not need to compete on interest rates because customers stay for convenience and brand recognition.
If you have money sitting in a national bank savings account earning less than 1%, moving it to an online bank or credit union costs nothing and takes a few days. You can set up a transfer from your old bank to your new bank online, or ask the new bank to pull the money for you. There is no fee, and your money is insured the entire time.
How to move money to a higher-rate account without losing access
You do not have to close your old account to open a new one. Many people keep their checking account at a national bank for convenience (ATMs, branches, bill pay) and move their savings to an online bank for the higher rate. You can transfer money between them as often as you want, and the transfer usually takes one to three business days.
To move money, log into your new bank's website and look for "transfer funds" or "link an external account." You will enter your old bank's routing number and your account number. The new bank will send two small deposits to your old account to verify you own it, then you confirm those amounts and the transfer is authorized. After that, you can move money back and forth whenever you want.
Alternatively, you can ask your old bank to send a wire transfer or cashier's check to your new bank. This is slower and may cost a small fee, but it works if you prefer not to link accounts online.
What happens to your rate if the bank lowers it
Banks can lower the interest rate on your savings account at any time, and they do not need your permission. When rates drop across the industry — which happens when the Federal Reserve lowers its benchmark rate — most banks lower their savings rates within weeks. You will not lose the money you already have, but new deposits and existing balances will earn the lower rate going forward.
This is why checking rates periodically matters. If you opened an account at 4.75% and the bank drops it to 3.50%, you can move your money to a different bank offering 4.50% without any penalty. There is no lock-in period on savings accounts, so you are free to leave whenever the rate no longer makes sense.
CDs are different: your rate is locked in for the entire term. If you open a one-year CD at 5.00% and rates drop to 3.00%, you keep earning 5.00% until the CD matures. This is one reason CDs appeal to people who want certainty, even if the rate is not the absolute highest available right now.
Frequently Asked Questions
How often do banks change their interest rates?
Banks can change rates daily, though most change weekly or monthly. Online banks tend to adjust faster than traditional banks. You should check the rate on any account you are considering opening within a day or two of actually opening it, because the rate you saw a week ago may have changed.
Is my money safe in an online bank if it pays higher interest?
Yes, as long as the bank is FDIC-insured. The FDIC insurance limit is $250,000 per account type per bank, regardless of whether the bank has physical branches. An online bank with FDIC insurance is just as safe as a national bank with thousands of branches.
Can I move my money to a higher-rate bank and then move it again if rates change?
Yes. There is no penalty for moving money between banks, and transfers are free. You can move your savings as many times as you want to chase higher rates. The only exception is CDs: if you withdraw money before the term ends, you pay an early withdrawal penalty, usually equal to a few months of interest.
What is the difference between APY and interest rate?
The interest rate is the percentage the bank pays on your balance. The APY is the total you earn in a year after accounting for compounding. Banks are required to show you the APY, which is why that is the number to compare when choosing between banks.
Do I need a minimum balance to get the advertised rate?
It depends on the bank and account. Some banks advertise a rate with no minimum. Others require $1,000, $10,000, or more. Always read the terms on the bank's website or call and ask before you open an account. A high rate with a high minimum may not be worth it if you do not have that much to deposit.
