The best CD rates change weekly, and they're almost never at the big national banks
The banks you see on every corner—Chase, Bank of America, Wells Fargo—typically offer CD rates well below what's available elsewhere. As of now, online banks and credit unions consistently offer rates 4 to 5 times higher than traditional brick-and-mortar banks for the same term length. A one-year CD at a major national bank might pay 0.5% annual percentage yield (APY), while an online bank offers 4.5% to 5.2% APY for the same one-year term.
The reason is straightforward: online banks have lower overhead costs. They don't maintain physical branches, so they pass savings to depositors through higher rates. Credit unions, which are member-owned rather than shareholder-owned, also tend to offer competitive rates because they're not trying to maximize profit.
Rate shopping matters because the difference compounds. On a $10,000 CD, the gap between 0.5% and 5% over one year is roughly $450 in your pocket. Over longer terms, that gap widens significantly.
Key Takeaways
- Online banks and credit unions consistently offer CD rates 4 to 5 times higher than national chain banks for identical term lengths.
- CD rates change weekly or even daily, so the "best" rate today may not be the best next week—check current rates before opening an account.
- Your deposits are protected up to $250,000 per account holder at any FDIC-insured bank, whether it's online or in-person.
- Shorter terms (3 to 6 months) sometimes offer nearly the same rate as longer terms, so comparing across different lengths helps you find the real best deal for your timeline.
Where rates are highest right now
Online banks hold most of the top positions. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank regularly appear in the top tier. These institutions update rates frequently—sometimes daily—so a rate that's highest on Monday may shift by Wednesday. You'll need to check their websites directly or use a rate comparison tool to see current offerings.
Credit unions are the second major source of competitive rates. The best rates are usually at credit unions you can actually join—many have membership requirements based on where you work, where you live, or what organizations you belong to. Navy Federal Credit Union, for example, offers strong CD rates but requires military affiliation or family connection to someone in the military. Pentagon Federal Credit Union has similar restrictions. Local credit unions in your area may also offer competitive rates; call or visit their websites to check.
A few regional banks—smaller institutions that operate in specific states or regions—occasionally offer rates competitive with online banks. These vary by location and change frequently, so they're worth checking if you bank locally already.
How to compare rates across different CD terms
Banks offer CDs in many lengths: 3 months, 6 months, 1 year, 2 years, 3 years, 5 years, and sometimes longer. The rate you get depends on the term you choose. Right now, a 1-year CD might pay 4.75% APY while a 5-year CD at the same bank pays 4.25% APY—or the reverse, depending on what the bank expects interest rates to do.
To find the best deal for your situation, decide first how long you can lock your money away without needing it. Then check rates across multiple banks for that specific term. Don't compare a 1-year rate at Bank A to a 5-year rate at Bank B; they're different products with different risk profiles.
Some banks offer "CD ladders"—opening multiple CDs with different maturity dates so money becomes available at regular intervals. This strategy lets you lock in current rates while keeping some cash accessible. If you're considering this approach, calculate the total interest across all the CDs you're planning to open, since the rates may differ by term.
What to check before opening a CD
FDIC insurance is your first verification. Every bank you consider should display its FDIC insurance status clearly on its website. This protection covers up to $250,000 per depositor per bank, so if you're opening a CD for more than that amount, you'll need to split it across multiple banks or find a credit union with different insurance rules. Online banks are FDIC-insured just like physical banks; the online format doesn't change the protection.
Check the early withdrawal penalty before you commit. If you need the money before the CD matures, the bank will charge a penalty—usually a certain number of months of interest. A 1-year CD might have a 6-month interest penalty, meaning if you withdraw at 8 months, you lose 6 months of the interest you've earned. Some banks offer "no-penalty" CDs with lower rates but more flexibility; these make sense if you're uncertain about your timeline.
Confirm the minimum deposit. Most online banks require $500 to $2,500 to open a CD. Some credit unions have lower minimums; others have higher ones. A few banks offer CDs with no minimum, though these are less common.
Look at how the bank compounds and credits interest. Most CDs compound daily and credit interest monthly or at maturity. This detail matters less for short-term CDs but becomes more significant over longer periods. The APY figure already accounts for compounding, so you can compare APY across banks directly without doing additional math.
Why the "best" rate today won't stay best for long
CD rates move in response to Federal Reserve decisions and broader economic conditions. When the Fed raises its benchmark rate, banks typically raise CD rates within days or weeks. When the Fed cuts rates, CD rates fall. This means a bank offering the highest 1-year rate this week might drop to middle-of-the-pack next week if rates shift.
This doesn't mean you should wait endlessly for rates to rise. If you need to lock in money for a specific period and rates are reasonable, opening a CD now is usually better than holding cash in a savings account earning 0.01% while you wait for rates that may never come. But it does mean checking rates from multiple sources before you decide, rather than assuming one bank will always be the best.
Comparing online banks, credit unions, and traditional banks
| Type | Typical Rate Range (1-Year) | Minimum Deposit | FDIC/Insurance | When to Choose |
|---|---|---|---|---|
| Online Banks | 4.5% to 5.2% APY | $500–$2,500 | FDIC-insured | You want the highest rates and don't need in-person service |
| Credit Unions | 4.0% to 5.0% APY | $500–$5,000 | NCUA-insured (similar to FDIC) | You're a member or can join, and want competitive rates with local service |
| National Banks | 0.3% to 1.0% APY | $1,000–$10,000 | FDIC-insured | You already bank there and value convenience over rate |
The rate differences are real and substantial. Moving $25,000 from a national bank CD at 0.5% to an online bank CD at 5.0% means earning roughly $1,125 more per year on the same money. That's not a small difference.
Red flags when shopping for CDs
Avoid any bank that doesn't clearly state its FDIC or NCUA insurance status. If you have to hunt for this information, move on. Legitimate banks display it prominently.
Be skeptical of promotional rates that explore only to new customers or only for the first few months. Some banks offer a high rate for the first 3 months, then drop it significantly. Read the terms carefully to see whether the rate you're seeing applies to the entire CD term or just part of it.
Don't assume a bank offering the highest rate is the safest choice. Rate leadership changes frequently. A bank offering 5.5% this month might offer 4.2% next month if rates shift. The safest approach is to check rates at multiple banks each time you're ready to open a CD, rather than assuming one bank will always be best.
Frequently Asked Questions
Can I move a CD from one bank to another if rates drop?
Not without a penalty. If you withdraw before maturity, you'll pay an early withdrawal penalty—usually several months of interest. It's rarely worth it unless the rate difference is enormous and you're early in the CD term. When your CD matures, you can move the money to a different bank offering a better rate without penalty.
Is an online bank CD as safe as a CD at my local bank?
Yes, if it's FDIC-insured. The FDIC protection applies to any bank, online or physical. Check the bank's website to confirm FDIC insurance status. Your $250,000 per account is protected the same way whether you visit a branch or manage everything online.
What's the difference between APY and interest rate on a CD?
APY (annual percentage yield) includes the effect of compounding—interest earned on interest. The stated interest rate does not. Banks are required to show you the APY, so compare APY figures across banks. A CD showing 5.0% APY will earn you more than one showing 5.0% interest rate, though the difference is usually small.
Should I open multiple CDs at different banks?
Only if you have more than $250,000 to deposit. Each bank's FDIC insurance covers up to $250,000 per depositor, so splitting large amounts across banks protects the full amount. If you have less than $250,000, opening multiple CDs at the same bank doesn't add protection, but it may make sense if you want different maturity dates or terms.
What happens to my CD if the bank fails?
The FDIC takes over and ensures you receive your full balance up to $250,000, plus any interest earned up to the date of failure. You don't lose money on an FDIC-insured CD due to bank failure. This protection is why checking FDIC status before opening any CD matters.
