Best CD Rates of September 2024

A CD is a “time deposit” that pays a fixed interest rate for a specific length of time. For most people, a CD is an account that you use at a bank or credit union, but you can also purchase CDs through brokerage accounts. Either way, you select a length of time to invest in the CD, and you earn interest during that time.

A CD holds your money for a specified length of time (such as six months or two years), and your bank or credit union pays you interest based on the amount of your deposit and the length of the term. 

When you use a CD, you typically commit to leaving your money in the account. In return for that commitment, banks usually pay higher interest rates than they do in more liquid savings accounts. But if you need your money before the term ends, you may have to pay an early withdrawal penalty.

Banks and credit unions often penalize you for withdrawing funds from a CD before the term is up. In many cases, they calculate the penalty as a certain number of months’ worth of interest. For example, Discover Bank charges six months’ worth of interest if you pull out of a 1-year CD early. That penalty increases to 18 months’ worth of interest on 5-year CDs.

Paying a penalty is never fun, and it can be particularly problematic when you cash out early in the term. Depending on how long your money stays in a CD, you might even receive less back than you originally deposited.

CDs often pay higher interest rates than you can earn in a savings account. Banks and credit unions tend to pay more when you agree to lock up your money for a specific length of time. Plus, if interest rates fall and the bank pays new customers lower rates, you keep earning the same higher APY throughout the term of your CD.

To earn a higher rate, however, you need to commit to leaving your money with the bank. Pulling out early may result in early-withdrawal penalties, which can wipe out your earnings. Also, if interest rates rise, you may be stuck with a comparatively low rate until your CD matures.

To help reduce your risk, some banks offer liquid CDs that allow you to withdraw funds early or request a rate increase. But there’s no such thing as a free lunch. Those products might start with lower rates than standard CDs, which is only fair, considering you can get out easily. More on that in the No-Penalty CD section below. You can also use a laddering strategy to manage some of the challenges that come with investing in CDs.

A CD ladder is a set of multiple CDs you purchase with different maturity dates, which helps you avoid locking up all of your money at once. With that approach, you might purchase a series of CDs with maturities in six-month increments. As a result, you periodically have cash available for planned (and unplanned) needs, or you can buy a new CD at the going rate. For example, if you have $10,000 to put into CDs, you might invest the following:

• 6-month CD: $2,500 
• 12-month CD $2,500 
• 18-month CD $2,500 
• 24-month CD: $2,500 

Ideally, every time one of these CDs matures, you would buy a new 24-month CD with the proceeds to begin the cycle again.

When your funds are federally insured, they’re safe from bank and credit union failures. There may be a brief delay in receiving your money (or no delay at all) immediately following a bank failure, but when you’re using CDs, you’re probably weren’t planning to use the funds immediately anyway. To verify that your cash is protected, look for the following types of coverage:

• FDIC insurance at banks
• NCUA coverage at federally-insured credit unions

Both of these programs insure your money up to $250,000 per depositor, per institution, so it’s critical to keep your balances below the insured limits. You might be able to have more than $250,000 insured at one place, depending on how your accounts are titled.

Several factors affect how much you earn from a CD. For starters, banks decide how competitive they want to be. If they have an appetite for new customers, they may nudge rates higher. Economic factors also influence CD rates. As rates rise or fall in financial markets, savings and CD rates tend to move in synchrony, although they might not react immediately (especially when it’s time to pay you more).

The length of your CD is critical. In general, you might expect longer-term CDs to pay more because you’re taking more risk—you’re committing to more months or years of unknowns. But the relationship is not always as direct as you might think. For example, if banks think rates might fall in the next several years, long-term CDs might pay rates that are similar to (or lower than) 1-year and 2-year CDs.

As you shop among banks, find a CD that’s the best fit for your finances. Pay careful attention to the features below.

• Interest rate: The higher the rate, the faster your money grows. The easiest way to compare rates is to use the annual percentage yield (APY), which banks typically provide for you. That quote takes compounding frequency into account and helps you make an apples-to-apples comparison.
• Minimum deposit: How much do you need to invest to use a CD? Some banks do not set any minimum, while others might require more than $1,000 to get started.
• Fees: Monthly fees in CD accounts are rare, but it's smart to verify that you won't pay additional charges to use a CD. Anything you pay will reduce your earnings.
• Joining fees: All of the credit unions we include on our best CD lists are available nationwide, but sometimes you’re required to make a donation to an organization in order to join the credit union. This fee is usually small, but it’s one more hoop you have to jump through to get the CD.
• Penalties: Examine the early-withdrawal penalties, and evaluate how likely it is that you’ll need to cash out early. Weigh the pros and cons of liquid CDs.

Calculate how much extra you can earn by getting the highest rate available, and decide if that’s what you really need. If you have a relatively small account balance, a difference of a few tenths of a percent may not make much difference and there may be other factors that are more important to you.

As you compare banks, you may notice language about compounding frequency (daily or monthly compounding, for example). All other things being equal, more frequent compounding is best. But you can ignore those details by simply comparing each bank’s APY, which includes compounding.

Some CDs allow you to withdraw money before maturity. These “no-penalty” or “liquid” CDs can provide flexibility for unexpected expenses and other situations. For example, you might be allowed to withdraw 100% of the money you deposit after six days, but the account pays a guaranteed rate of interest for 11 months. 

What’s the catch? In many cases, no-penalty CDs start at a lower rate than standard, inflexible CDs. You enjoy the benefit of flexibility, and the bank has less certainty about how long it can use your money. As a result, you earn slightly less.

You typically have to pay tax on the interest you earn from CDs in taxable accounts, including joint accounts, individual accounts, and other types of accounts. If you use CDs in a retirement account, such as an IRA, you generally would not pay taxes on the earnings each year—but you might owe taxes when you take distributions from that account.

CDs are excellent tools for growing your money, but other products from banks and credit unions might also do the job.

Savings accounts provide more flexibility when you need money, but they don’t have fixed rates. That can work in your favor when rates rise. But if rates fall or remain stagnant, you might be better off in a CD.

Money market accounts are similar to savings accounts, but they may make it easier to spend money from your account. Some money market accounts provide a debit card or checkbook for spending, while others may require you to move your savings to a checking account before you spend.
