CD rates change daily, so the "best" rate depends on your bank, the CD term you choose, and when you lock in your money
There is no single bank that always has the highest CD rates. Banks adjust their rates based on what the Federal Reserve does, how much cash they need to attract, and competition from other banks. A bank offering 5.25% on a one-year CD might offer only 4.80% on a five-year CD, while a different bank does the opposite. The rate you see today will not be the rate you see next week.
The practical approach is to check rates across three categories: online banks (which usually offer higher rates than brick-and-mortar branches), credit unions, and your current bank. Then compare the specific term you want—three months, one year, three years, five years—because the best rate for one term is rarely the best for another.
Key Takeaways
- Online banks typically offer higher CD rates than traditional banks because they have lower overhead costs, though you cannot walk into a branch to make deposits or withdrawals.
- Credit unions sometimes match or beat online bank rates, especially for members, so checking your own credit union before comparing online options saves time.
- CD rates vary by term length—a bank's best one-year rate may be lower than its five-year rate or vice versa, so compare the specific term you need.
- Rate comparison sites like Bankrate, DepositAccounts, and NerdWallet update daily and let you filter by term and minimum deposit, which is faster than visiting each bank's website.
- The difference between the highest and lowest rates on the same term can be 0.5% to 1.5%, which adds up to real money over the CD's life.
Online banks usually offer the highest rates
Online banks like Marcus, Ally, American Express Personal Savings, and Discover typically post the highest CD rates because they do not maintain physical branches. That lower cost structure means they can pass higher rates to depositors. As of the time this guide was written, online banks were offering rates in the 4.5% to 5.5% range depending on the term, though these rates shift weekly.
The trade-off is access. You cannot deposit cash at a branch or speak to someone in person. All deposits and withdrawals happen online or by mail. If you need to add money to a CD before it matures, you cannot—CDs are locked-in products. If you need to withdraw early, you pay a penalty (usually three to six months of interest). For people who are comfortable with online banking and do not need to touch the money, online banks are the fastest way to find competitive rates.
Credit unions may match online rates for members
Credit unions are member-owned, not shareholder-owned, so they sometimes offer CD rates that rival online banks. Your rate depends on which credit union you join and whether you meet their membership requirements. Some credit unions are open to anyone in a geographic area; others require you to work for a specific employer, belong to an organization, or have a family member who is already a member.
If you already belong to a credit union, call or log in to check their CD rates before comparing online banks. If you do not belong to one, search the CO-OP Network or Shared Branch locator to find credit unions near you and learn their membership rules. Joining often takes 15 minutes online, and some credit unions waive membership fees.
Traditional banks offer lower rates but more convenience
Banks with physical branches—Chase, Bank of America, Wells Fargo, Citibank—typically offer lower CD rates than online banks or credit unions. A traditional bank might offer 3.5% to 4.5% on a one-year CD while an online bank offers 5.0% to 5.5% for the same term. The difference compounds over time: a $10,000 CD earning 3.5% for one year yields $350 in interest, while the same CD at 5.5% yields $550.
The advantage of a traditional bank is convenience. You can deposit cash in person, speak to someone if something goes wrong, and access your account at thousands of branches. If you already bank there and value that access, the lower rate might be worth it. But if you are willing to bank online, you will earn significantly more.
How to compare rates across banks and terms
Rate comparison sites update daily and let you filter by CD term, minimum deposit, and account type. Bankrate, DepositAccounts, and NerdWallet all show rates from dozens of banks in one place. Enter the term you want (three months, one year, five years) and the minimum amount you plan to deposit, and the site will rank banks by rate.
After you find the highest rate for your term, visit that bank's website directly to confirm the rate has not changed and to check the early withdrawal penalty. Penalties vary widely—some banks charge three months of interest, others charge six months or a flat fee. Read the CD's terms before you commit. If the rate has dropped since the comparison site updated, check the second-highest option.
Keep in mind that some banks offer promotional rates for new customers only, or rates that apply only to CDs opened through a specific channel (like a mobile app). The comparison site should note these restrictions, but confirm on the bank's website.
What happens when rates drop after you lock in
Once your CD matures, you have a window—usually seven to ten days—to decide what to do with the money. If rates have dropped, you can renew the CD at the lower rate, move the money to a savings account, or shop for a better rate elsewhere. If rates have risen, you can move to a higher-paying CD at another bank.
Some banks automatically renew your CD at their current rate if you do not tell them otherwise. Read your CD agreement to see whether your bank does this. If it does and you want to shop around when the CD matures, set a calendar reminder for a few days before the maturity date so you have time to move the money.
The difference between APY and interest rate
Banks advertise CD rates as APY (annual percentage yield), which includes the effect of compounding. The APY is the number you should compare across banks because it reflects what you actually earn. Some banks compound interest daily, others monthly or quarterly, but the APY accounts for that difference. You do not need to do any math—just compare the APY numbers directly.
The early withdrawal penalty is separate from the rate. If you withdraw before the CD matures, the bank deducts the penalty from your interest earnings or principal. A $10,000 CD earning 5% for one year yields $500 in interest, but if you withdraw after six months and the penalty is three months of interest, you lose $125 and walk away with $10,375 instead of $10,500.
Frequently Asked Questions
Do I have to use my current bank for a CD?
No. You can open a CD at any bank or credit union that accepts deposits from your state. Many people open CDs at online banks they have never visited in person. The FDIC insures up to $250,000 per depositor per bank, so your money is protected regardless of whether the bank has branches.
What if I need the money before the CD matures?
You can withdraw it, but you will pay an early withdrawal penalty. The penalty is usually three to six months of interest, though some banks charge a flat fee. Calculate whether the penalty is worth it before you withdraw. If you think you might need the money, a high-yield savings account with no withdrawal penalty might be a better choice than a CD.
Can I ladder CDs to get higher rates and access to money sooner?
Yes. CD laddering means buying multiple CDs with different maturity dates—for example, one-year, two-year, and three-year CDs all at once. As each one matures, you can renew it at the longest term to keep the ladder going, or withdraw the money. This strategy lets you access some of your money each year while keeping the rest locked in at higher rates.
Are online bank CDs as safe as CDs at traditional banks?
Yes. Online banks are FDIC-insured just like traditional banks. Your $250,000 per account is protected if the bank fails. The only difference is that you cannot walk into a branch, but your money is equally safe.
How often do CD rates change?
Banks change CD rates weekly or even daily, depending on Federal Reserve decisions and market conditions. If you see a rate you like, locking it in immediately is usually better than waiting, because rates can drop overnight. Comparison sites show when rates were last updated, so you can see how current the information is.
