The best CD rates come from online banks, credit unions, and a few brick-and-mortar institutions, and they change weekly based on what the Federal Reserve does with interest rates.

Right now, the banks offering the highest rates are mostly online-only: Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank regularly appear at the top of rate comparison lists. Credit unions often match or beat these rates for their members, especially if you belong to a larger institution or a credit union network. A few traditional banks like Vanguard and Schwab also offer competitive CDs, though their rates tend to lag behind online competitors.

The catch is that "best" changes constantly. A bank that leads this week may drop next week. The Federal Reserve's interest rate decisions drive the whole market, so when the Fed moves, all CD rates move within days. This means the rate you see today might be different by the time you open an account tomorrow.

Key Takeaways

  • Online banks consistently offer higher CD rates than traditional banks because they have lower overhead costs and pass savings to depositors.
  • Credit unions can match or exceed online bank rates for members, so check your own credit union first before comparing elsewhere.
  • CD rates shift weekly in response to Federal Reserve decisions, so a rate that is highest today may not be highest next month.
  • Rate comparison sites like Bankrate, DepositAccounts, and NerdWallet update daily and let you filter by CD term length and minimum deposit.
  • The difference between the highest and lowest rates on a five-year CD can mean hundreds of dollars in extra interest, so comparing before you commit matters.

How to compare CD rates across banks

Start with a rate comparison site rather than visiting banks one by one. Bankrate, DepositAccounts, and NerdWallet all update their listings daily and let you sort by CD term (three months, six months, one year, five years, and so on) and by minimum deposit required. These sites do not sell your information or push you toward any particular bank—they make money from referral fees, so they benefit when you find what you need and leave.

When you find a rate that interests you, visit the bank's website directly to confirm the rate is still current and to read the fine print. Some banks advertise a promotional rate that applies only to new customers or only for the first deposit. Others require you to maintain a minimum balance or set up automatic transfers to may have access to. The comparison site will usually note these conditions, but the bank's own terms page is the source of truth.

Pay attention to the annual percentage yield (APY), not just the interest rate. APY accounts for how often the bank compounds your interest—daily, monthly, or quarterly—so it shows you the actual return you will earn. Two banks might advertise the same rate, but the one that compounds daily will pay you slightly more.

Why online banks lead on rates

Online banks have no physical branches, no tellers, and no real estate costs. They pass those savings to depositors by offering higher rates on savings accounts and CDs. They also compete fiercely for deposits because they cannot rely on local customers walking in the door—they have to win you over with rate and service.

Traditional banks with branch networks can afford to offer lower rates because they attract customers for other reasons: convenience, the ability to speak to someone in person, or existing relationships. If you value that convenience, you may accept a lower rate. If you are purely chasing the highest return, online banks are usually the answer.

Credit unions operate on a membership model and return profits to members rather than shareholders. This structure often allows them to offer rates that match or beat online banks. The downside is that you must be a member—usually by working for a specific employer, belonging to a certain organization, or living in a specific geographic area. If you may have access to, check your credit union's CD rates before looking elsewhere.

Understanding CD terms and how they affect your rate

A CD term is how long you agree to lock your money away. Common terms are three months, six months, one year, two years, three years, and five years. Longer terms almost always pay higher rates because the bank gets to hold your money for longer and lend it out at a profit. A five-year CD might pay 4.50% APY while a one-year CD pays 4.00% APY at the same bank.

The tradeoff is flexibility. If you lock money in a five-year CD and need it after two years, you will pay an early withdrawal penalty—usually three to six months of interest. That penalty can wipe out your gains if rates have risen in the meantime. If you think you might need the money sooner, a shorter-term CD or a high-yield savings account (which has no withdrawal penalty) may be safer.

Some banks offer "no-penalty" CDs that let you withdraw your money early without a penalty, but they pay lower rates to offset that risk. These make sense if you want CD-like returns but need flexibility. Compare the no-penalty rate against a regular CD rate and a high-yield savings account rate to see which fits your situation.

Minimum deposits and account requirements

Most online banks require a minimum deposit of $500 to $2,500 to open a CD, though some have no minimum at all. A few banks require higher minimums—$10,000 or more—in exchange for slightly higher rates. Check the minimum before you start the application process so you do not waste time on a bank you cannot fund.

Some banks also require you to have a checking account with them or to set up automatic transfers from another account. These requirements are usually stated clearly on the CD product page. If you do not want to open a checking account, filter those banks out and move on.

A few banks offer "bump-up" CDs that let you request a rate increase once during the term if rates rise. This feature costs you a slightly lower starting rate, but it can pay off if the Fed raises rates while your CD is open. Weigh whether you think rates will rise and whether the starting rate difference is worth the potential upside.

When to lock in a rate versus waiting

You cannot predict what the Federal Reserve will do, so do not try. If the current rate is acceptable to you and you have money you will not need for the CD term, lock it in. Waiting for rates to rise is a form of market timing, and it usually backfires—you miss months of interest while rates stay flat or fall.

The only exception is if you are certain rates will fall soon. If the Fed has signaled rate cuts and economic data supports that signal, waiting a few weeks might make sense. But if you are uncertain, the may provide return of locking in a rate today beats the hope of a higher rate tomorrow.

One strategy is to "ladder" your CDs: open several CDs with different terms at the same time. A one-year, a two-year, and a three-year CD all maturing at different times give you flexibility. When the one-year matures, you can decide whether to renew it at the new rate or move the money elsewhere. This approach lets you take advantage of rate changes without locking all your money away for years.

How FDIC insurance protects your CD

The Federal Deposit Insurance Corporation (FDIC) insures deposits at member banks up to $250,000 per depositor, per bank, per account category. This means if the bank fails, you get your money back up to that limit. Most people with CDs under $250,000 are fully protected.

If you have more than $250,000 to invest in CDs, you can spread it across multiple banks to stay within the insurance limit at each one. For example, $500,000 split between two banks ($250,000 at each) is fully insured. Some people use this strategy to earn high rates on large sums while keeping everything protected.

Credit unions are insured by the National Credit Union Administration (NCUA) under the same $250,000 limit. The protection works the same way, so you can feel equally confident in a credit union CD as a bank CD.

Frequently Asked Questions

Do I have to pay taxes on CD interest?

Yes. CD interest is taxable income in the year you earn it, even if you do not withdraw the money until the CD matures. Your bank will send you a 1099-INT form showing how much interest you earned, and you report that on your tax return. If the CD is in a retirement account like an IRA, the interest is tax-deferred.

What happens when my CD matures?

Most banks automatically renew your CD at the current rate for the same term unless you tell them otherwise. You usually have a grace period (often 7 to 10 days) to withdraw the money or move it elsewhere without penalty. Check your bank's renewal policy so you know what to expect and can act if you want to move your money.

Can I open multiple CDs at the same bank?

Yes. You can open as many CDs as you want at the same bank, and each one is insured separately up to $250,000. Many people open multiple CDs with different terms to create a ladder, or open several CDs with the same term to spread a large deposit across the insurance limit.

Is a CD better than a high-yield savings account?

CDs usually pay slightly higher rates, but you cannot touch the money without paying a penalty. High-yield savings accounts pay less but let you withdraw anytime. Choose a CD if you have money you will not need for a set period; choose a savings account if you want flexibility or might need the money sooner.

How often do CD rates change?

Banks can change their CD rates at any time, and most do so weekly or even daily in response to market conditions and Federal Reserve decisions. The rate you lock in when you open the CD is may provide for the full term, but new CDs opened later will reflect the new rates.
