The banks offering the best CD rates change weekly, and online banks consistently beat brick-and-mortar branches

The highest CD rates come from online banks and credit unions, not from the bank where you keep your checking account. As of now, online institutions are paying between 4.5% and 5.3% APY on one-year CDs, while traditional banks with physical branches typically offer 0.5% to 1.5% APY on the same term. The gap exists because online banks have lower overhead costs and compete directly on rate to attract deposits.

Rates shift constantly—sometimes daily—so the "best" rate today may not be the best next week. What matters more than chasing the single highest rate is understanding which institutions are reliable, what terms they offer, and whether the rate difference is worth moving your money. A 0.5% difference on a $10,000 CD over one year is $50. A 2% difference is $200. The math changes based on your deposit size and how long you lock the money away.

The institutions that consistently rank at the top of rate lists include online banks like Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank. Credit unions like Pentagon Federal Credit Union and Connexus Credit Union also compete for top rates. None of these are new or risky—they all carry FDIC or NCUA insurance up to $250,000 per account holder, per institution.

Key Takeaways

  • Online banks and credit unions offer CD rates two to four times higher than traditional brick-and-mortar banks because they have lower operating costs.
  • The highest rates change weekly, so comparing rates across multiple institutions on the day you plan to deposit is more useful than reading a static list.
  • Your money is protected up to $250,000 through FDIC insurance at banks or NCUA insurance at credit unions, regardless of whether the institution is online or physical.
  • A CD ladder—splitting your deposit across multiple terms—lets you access some of your money sooner while keeping other portions locked at higher rates.
  • Early withdrawal penalties vary widely; some institutions charge three months of interest, others charge six months or more, so read the terms before you commit.

How to compare rates across institutions in real time

Rate comparison sites like Bankrate, DepositAccounts, and DepositAccounts.com pull current rates from hundreds of banks and credit unions and update them multiple times daily. These sites let you filter by CD term (three months, six months, one year, five years, and so on) and sort by APY. The rates shown are real—you can click through to the institution's website and see the same number.

When you find a rate that interests you, visit the bank's website directly to confirm the rate is still live and to read the full terms. Rates can change between the time a comparison site updates and the time you open the account. The bank's website is the source of truth.

Pay attention to the minimum deposit required. Some institutions require $500 to open a CD; others require $25,000 or more. If you have $5,000 to deposit, a bank requiring $25,000 minimum is not an option for you, even if it shows the highest rate.

What early withdrawal penalties actually cost you

Every CD has an early withdrawal penalty—the fee you pay if you need the money before the term ends. The penalty is usually stated as a number of months of interest. A CD with a three-month penalty means you lose three months' worth of the interest you would have earned. A six-month penalty costs more.

The math matters. If you have a one-year CD at 5% APY with a six-month penalty, and you withdraw after six months, you lose six months of interest (roughly 2.5% of your deposit). If your deposit was $10,000, that penalty is about $250. You still come out ahead of a savings account, but the penalty is real.

Some online banks offer "no-penalty CDs" that let you withdraw early without losing interest, though the rate on these is usually lower than on traditional CDs. If you think you might need the money, a no-penalty CD at 4.5% might be smarter than a traditional CD at 5.2% with a six-month penalty.

Online banks versus credit unions: which offers better rates

Both online banks and credit unions can offer competitive rates. The difference is in how they operate. Online banks are for-profit institutions that compete on rate to attract deposits. Credit unions are member-owned nonprofits that often pass savings back to members through higher rates and lower fees.

Credit unions sometimes offer higher rates than online banks, but you have to be a member to open an account. 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. Pentagon Federal Credit Union, for example, is open to military members and their families. Connexus Credit Union is open to anyone.

If you already belong to a credit union, check their CD rates first. If you don't, you can search for credit unions you're may be able to access to join using the CO-OP network locator or by searching "credit unions near me." If none are available to you or their rates are lower, online banks are your next stop.

CD ladders: how to access your money sooner while keeping rates high

A CD ladder is a strategy where you split your deposit across multiple CDs with different maturity dates. Instead of putting $10,000 into a single five-year CD, you might put $2,000 each into one-year, two-year, three-year, four-year, and five-year CDs. As each CD matures, you can withdraw the money or roll it into a new CD at whatever the current rate is.

The advantage is liquidity. With a single five-year CD, your money is locked away for five years. With a ladder, $2,000 becomes available every year. If you need cash in an emergency, you have access without paying an early withdrawal penalty. If rates rise, you can reinvest maturing CDs at the new higher rate.

The disadvantage is that you lock in lower rates on the longer-term CDs. If you ladder into a five-year CD at 4.5% and rates jump to 5.5% the next year, you're stuck at 4.5% for five years. But if rates fall, you're protected on the longer-term portion of your ladder.

FDIC and NCUA insurance: what actually protects your deposit

Every dollar you deposit in a CD at an FDIC-insured bank is protected up to $250,000 if the bank fails. Every dollar at an NCUA-insured credit union is protected up to $250,000 if the credit union fails. This protection is real and has been tested many times—during the 2008 financial crisis, depositors at failed banks got their money back.

The $250,000 limit applies per depositor, per institution. If you have $250,000 in CDs at Marcus and another $250,000 at Ally, both are fully protected. If you have $400,000 at Marcus, only $250,000 is protected. You can verify that a bank is FDIC-insured by searching the FDIC's Bank Find tool. You can verify credit union insurance through the NCUA's Credit Union Locator.

This insurance applies regardless of the interest rate the institution offers. A bank offering 5% APY is just as safe as one offering 1% APY, as long as both are FDIC-insured.

When a lower rate might actually be the right choice

The highest rate is not always the best option. If the highest-rate bank requires a $25,000 minimum and you have $5,000, you cannot use it. If the highest-rate CD has a six-month early withdrawal penalty and you might need the money in four months, the penalty could wipe out your gains. If the highest-rate bank is unfamiliar and you're uncomfortable with it, a slightly lower rate at an institution you trust is reasonable.

You should also consider how long you plan to keep the money locked away. If you're saving for something specific that happens in two years, a two-year CD locks in a rate for exactly that period. If you choose a five-year CD instead, you're betting that rates won't rise significantly over the next three years after your money matures. That bet might not be worth an extra 0.3% APY.

The practical approach: find the top three or four rates for your desired term, check the minimum deposit and early withdrawal penalty for each, and pick the one that fits your situation. A 0.2% difference in rate is not worth switching to an institution with worse terms or one you don't trust.

Frequently Asked Questions

Do I have to keep my CD at the same bank where I have my checking account?

No. You can open a CD at any FDIC-insured bank or NCUA-insured credit union, regardless of where you bank. Many people open CDs at online banks specifically because those banks offer higher rates, then keep their checking account at a local branch for convenience.

What happens when my CD matures?

When the term ends, the bank deposits your principal plus interest into the account you specified during setup. You then have a grace period—usually seven to ten days—to decide whether to roll the money into a new CD or withdraw it. If you do nothing, most banks automatically roll it into a new CD at the current rate. Check your bank's policy before the maturity date if you want to avoid automatic renewal.

Can I add money to a CD after I open it?

No. CDs are fixed-term, fixed-amount products. Once you open a CD, you cannot add more money to it. If you want to deposit additional funds, you open a separate CD. This is another reason CD ladders are useful—you can open multiple CDs at different times and terms.

Is the interest on a CD taxable?

Yes. CD interest is ordinary income and is taxed at your regular income tax rate. The bank will send you a 1099-INT form at the end of the year showing the interest you earned. You report this on your tax return. This is true even if you don't withdraw the money—you owe tax on the interest in the year it was earned.

What if I need the money before the CD matures?

You can withdraw it, but you'll pay the early withdrawal penalty stated in the CD's terms. The penalty is deducted from your deposit or interest. If the penalty is larger than the interest you've earned, you'll get back less than you deposited. This is why understanding the penalty before you commit is important.
