CD rates change weekly, so the "best" rate today belongs to whichever bank is offering the highest yield on the term you want

There is no single bank that always offers the best CD rates. Banks compete by raising and lowering their rates based on what the Federal Reserve does, how much cash they need to attract, and what their competitors are offering. A bank offering 5.25% this week might drop to 4.75% next week. The bank offering 4.50% might jump to 5.40% the week after.

The practical approach is to check rates across multiple banks before you deposit money, then move quickly if you find what you want. The highest rates are almost never at the big national banks—they are at online banks, credit unions, and smaller regional banks that need to attract deposits to grow.

Rate-comparison sites like Bankrate, DepositAccounts, and the FDIC's own rate search tool let you filter by CD term (3 months, 6 months, 1 year, 5 years, and so on) and see what each institution is currently paying. These sites update daily or multiple times per day, so the rates you see are current.

Key Takeaways

  • Online banks and credit unions typically offer higher CD rates than traditional brick-and-mortar banks because they have lower overhead costs.
  • The highest rate available changes weekly or even daily, so you should compare rates across at least three to five institutions before depositing.
  • Shorter-term CDs (3 to 6 months) and longer-term CDs (4 to 5 years) sometimes offer different rates, so check the specific term you want.
  • All deposits up to $250,000 per depositor per bank are protected by FDIC insurance, so a smaller bank with a higher rate carries the same deposit protection as a large national bank.

Online banks usually have the highest rates

Online banks have no physical branches, no tellers, and no building leases. That lower cost structure means they can pass higher rates to depositors. Banks like Marcus (owned by Goldman Sachs), Ally, American Express Personal Savings, and Vanguard Bank have consistently offered CD rates in the top tier for the past two years.

The trade-off is that you cannot walk into a branch or speak to someone in person. You open the account online, fund it by wire transfer or ACH, and manage everything through their website or app. If you need to withdraw money early, you call or email customer service. Most online banks charge an early withdrawal penalty if you break the CD before maturity—typically three to six months of interest, though this varies by term.

Online banks are FDIC-insured the same way traditional banks are. Your $250,000 per account type (savings, checking, CD, money market) is protected even if the bank fails.

Credit unions often match or beat online bank rates

Credit unions are member-owned cooperatives, not profit-driven corporations. Many use their earnings to offer better rates to members. If you belong to a credit union, check their CD rates before you look elsewhere—they may already be competitive or better than what online banks are offering.

You must be a member to open a CD at a credit union, and membership rules vary. Some credit unions are open to anyone in a certain geographic area or profession. Others require you to work for a specific employer or belong to a specific organization. A few allow you to join by making a small donation to a nonprofit partner.

Credit union deposits are insured by the National Credit Union Administration (NCUA), not the FDIC, but the coverage is identical: $250,000 per account type per member per institution. If you already have a savings account at a credit union, opening a CD there takes minutes.

Regional and smaller national banks sometimes offer competitive rates

Banks like Connexus Credit Union, Connexus Bank, Discover Bank, and some regional institutions (Sallie Mae Bank, Investors Bank, Flagstone Bank) periodically offer rates that compete with or exceed online banks. These banks are smaller than Chase or Bank of America but larger than a single-branch community bank.

The advantage is that some have customer service by phone or chat, and a few have limited branch access. The disadvantage is that their rates are less consistent—they may offer a top-tier rate for one month and then drop significantly the next month as their deposit needs change.

Check these banks on the same rate-comparison sites you use for online banks. They appear in the same search results, so you can compare them side by side with online options.

How to compare rates across different CD terms

CD rates vary by term length. A 6-month CD might pay 4.50%, while a 1-year CD pays 5.10%, and a 5-year CD pays 4.80%. The relationship between term and rate is not consistent—sometimes longer terms pay more, sometimes shorter terms pay more, depending on what the Federal Reserve is expected to do.

When you search for rates, filter by the specific term you want. If you plan to lock up money for 2 years, do not compare 5-year rates. If you want to revisit your money in 6 months, search for 6-month CDs only. The highest rate on a 5-year CD means nothing if you need access sooner.

Write down the top three to five rates you find for your chosen term, note which bank offers each, and check the early withdrawal penalty for each one. Then open the account at the bank with the highest rate, as long as the early withdrawal penalty is not so steep that it would wipe out your gains if you had to break the CD.

What to watch for when comparing rates

The advertised rate is the Annual Percentage Yield (APY), which includes compounding. This is the number you should compare across banks—it is the actual return you will earn. Do not confuse it with the interest rate, which is slightly lower and does not account for how often interest is compounded.

Check the minimum deposit required. Most online banks require $500 to $1,000 to open a CD. Some credit unions require $500 or less. A few banks have no minimum. If you have only $250, you may not be able to open a CD at every bank offering the highest rate.

Read the early withdrawal penalty before you deposit. If a bank offers 5.50% but charges six months of interest as a penalty, and you think you might need the money in 8 months, the penalty could eat into your gains. Some banks charge a flat fee ($25 or $50) instead of interest-based penalties, which may be better or worse depending on how much you are depositing.

Frequently Asked Questions

Do I have to use a big bank to get FDIC protection?

No. FDIC insurance is not based on bank size. Any bank that displays the FDIC logo and is listed on the FDIC's bank search tool is insured up to $250,000 per account type. Online banks, regional banks, and small banks are all FDIC-insured if they are members of the FDIC.

What if I find a rate that looks too good to be true?

Check the bank's name on the FDIC website or the NCUA website (for credit unions). Verify the rate on the bank's official website, not just on a comparison site. If a rate is significantly higher than competitors and the bank is not FDIC or NCUA-insured, it is likely a scam or the bank is taking on excessive risk.

Can I move money between CDs at different banks to chase higher rates?

Yes, but only when your current CD matures. If you break a CD early to move to a higher rate elsewhere, the early withdrawal penalty will reduce or eliminate your gain. Wait for maturity, then deposit the full amount (principal plus interest) into a new CD at the bank offering the best rate at that time.

Do online banks ever offer promotional rates higher than their regular rates?

Yes. Some banks offer a higher rate for a limited time to attract new customers, or a bonus rate for the first few months of a CD. Read the terms carefully—the promotional rate may apply only to new customers, only to deposits above a certain amount, or only for the first 3 months. After the promotion ends, the rate drops to the standard rate.

Should I split my money across multiple CDs to get higher rates?

Only if different banks are offering different rates for different terms. If you have $10,000 and want to lock it up for 2 years, putting it all in one 2-year CD at the highest-rate bank is simpler than splitting it across multiple banks. However, if you want flexibility—some money available in 6 months, some in 1 year, some in 2 years—splitting across CDs with different maturity dates makes sense, and you can choose the bank with the best rate for each term.
