In the News

CD rates reached higher in 2023 than we’d seen in more than 20 years, pushed up by the Federal Reserve’s rate-hike campaign that began in March 2022 to tame decades-high inflation. For its last four meetings, however, the Fed has held the federal funds rate steady, and signaled on Jan. 31 that the committee’s rate-hike cycle has almost certainly ended. While most Fed members expect two to four rate decreases will occur in 2024, the Fed has cautioned that it could be some time before the first cut is implemented. CD yields closely follow the fed funds rate, so the Fed’s holding pattern has caused CD rates to plateau. But once it appears the Fed is ready to make a rate cut, CD rates are expected to fall.

Where more than one institution pays the same top rate, our rankings prioritize CDs by the shortest term, then the CD requiring the smallest minimum deposit. If there is still a tie, we then rank alphabetically by institution name.

What Is an 18-Month CD and How Does It Work?

Certificates of deposit (CDs) are bank or credit union accounts in which you agree to hold your funds on deposit without withdrawals for a prearranged period. Thus, an 18-month CD requires you to keep the funds untouched for about a year and a half. For our rankings, we consider 18-month CDs to be anything with a term of 15 to 20 months.

In exchange for giving up access to your funds, you'll generally be rewarded with a higher interest rate than the bank pays on savings and money market accounts that allow flexible withdrawals.

When opening a CD, you deposit a lump sum of funds into the account at or above the minimum required deposit for that CD. The funds will then sit in the account for 18 months, earning interest along the way. When the CD hits its maturity date, you can take the funds plus their earned interest out of the account with no penalty.

Fast Fact

When asked in January what they would invest in if they had an extra $10,000, 9% of Investopedia readers said they would open a CD, in fourth place behind individual stocks, ETFs, and stock index funds. That’s down from 11% in December.

Pros and Cons of 18-Month CDs

Pros

  • Offers a guaranteed rate for 18 months: No matter what happens with the Federal Reserve and interest rates, the bank cannot change the APY you secure when you sign your CD agreement and make your deposit.
  • May pay a higher APY than other terms: Shopping around is critical, as rates can vary widely across institutions and also across different CD lengths.
  • Pays reliable and predictable earnings: Because your CD rate is fixed and your term is known, you can calculate exactly how much your earnings will amount to once the CD matures.
  • Is safe and virtually risk-free: CDs opened at an FDIC bank or NCUA credit union are federally insured, protecting up to $250,000 of your deposits in the unlikely event that the institution fails.
  • Can deter the temptation to spend since funds are tied up: Withdrawing your funds before the CD matures will trigger an early withdrawal penalty, which may be enough to stop you from pulling the funds out for unplanned spending.

Cons

  • Incurs a penalty if you withdraw early: Every bank and credit union specifies their policy on how they'll calculate your penalty if you don't keep your CD funds deposited until maturity. Typically, the penalty is a number of months' interest that you'll forfeit.
  • Allows only one deposit amount: With most CDs, you get one chance to decide how much you want to invest in the certificate. Additional deposits are generally not allowed.
  • If rates fall, you may wish you'd opted for a longer term: Investing in a longer CD would have allowed you to retain a good rate for a longer period of time
  • If rates rise, you'll be locked at a lower rate until maturity: If you lock into an 18-month CD and then rates rise, you'll be stuck with your current rate until you can withdraw your funds.

Important

Though consumers tend to think about CD maturity terms in nice round numbers, be sure to consider odd-term CDs, such as 15-month, 18-month, or 21-month certificates. It's not uncommon for promotional rate CDs to have unusual durations, so don't limit yourself to only the conventional terms.

Factors to Consider When Choosing a CD

When choosing a CD, consider the following factors:

  • Your goals: Both short-term financial goals and long-term financial goals are important.
  • How much money you can deposit: CDs have minimums, so if you only have $500 to deposit, you'll need to find a CD with that minimum balance requirement.
  • How long you can leave that money in the CD without touching it: This will help you determine the right term—whether that's a one-year CD or a three-year CD.
  • Interest rates offered for your term and minimum deposit: The higher the rate, the more you will earn on your deposit during the CD term.
  • CD type: Is it a bump-up CD or a regular CD? This will ensure you're choosing one that meets your needs and goals.

Once you choose a CD, open the account, and deposit your money to start earning interest.

Hilarey Gould, Editorial Director for Financial Products and Services at Investopedia

When choosing an 18-month CD, be sure to review the early withdrawal penalty. If you think you might need to withdraw your money before the CD matures, look for a CD with a lower penalty so that you end up with the most money possible when you withdraw. If you are positive that you won't touch the money in the CD until maturity, you may feel comfortable opening a CD with a more expensive penalty.

How to Find the Best 18-Month CD Rates

This list includes the best 18-month CD rates, meaning that they are the highest 18-month CD rates nationwide. To find you the top 18-month CD rates, we look at hundreds of banks, credit unions, and other financial institutions every day and gather the CDs with the highest rates that are available nationwide, including CDs with terms of 15 to 20 months.

When choosing an 18-month CD, consider the amount of money you want to deposit, the interest rate on the CD, and the early withdrawal penalty. For example, if a 20-month CD offers a 5.00% interest rate on a $25,000 deposit, but a 12-month withdrawal penalty, you may want to compare it with a 15-month CD with the same deposit but a 6-month withdrawal penalty. This comparison is important to think about because if you need that money back sooner than maturity, you need to know what amount of interest you'll lose by withdrawing early. With that in mind, you'll need to first compare your options based on your deposit amount, then look at the rate and early withdrawal penalty.

Alternatives to 18-Month CDs

18-Month CDs vs. Other CD Terms

Anytime you're choosing a CD, a decision on the length of term is one of the most critical considerations. You'll want to select a term that you feel reasonably confident you can stick with, so that you won't incur a penalty for withdrawing early.

Instead of an 18-month CD, you could choose a shorter certificate to limit the amount of time your funds are tied up, but you may have to settle for a slightly lower rate. The same is true if you go with a longer-term CD: rates could be lower than what you can earn on 18 months. It all depends on the current rate environment, so it's important that you shop around.

For example, if rates are higher now than you think they will be in the future, locking in one of today's rates for as long as possible can be a smart move, so that you'll retain your APY for a longer period than if you chose a shorter-term CD.

CDs vs. Savings and Money Market Accounts

Instead of locking up your money in an 18-month CD, you can instead keep it in one of several types of liquid accounts. Keeping it in a checking account is one option, providing ultimate convenience and flexibility. But since checking accounts generally pay zero interest, it's a poor choice for your savings.

Opening a top-paying high-yield savings account or a money market account is a better option, enabling you to earn a competitive return on your funds. The downside compared to a CD, however, is that savings and money market accounts pay a variable rate, which means that if interest rates go down in the future, so will the rate you're earning in these accounts.

The same is true for cash reserve and money market funds at brokerage firms. Many of these pay much lower rates than you can earn with a high-yield savings account at a top-paying bank. But even when the APY on a brokerage cash account is competitive, it too is a variable rate that you can't lock in like you can with a CD.

CDs vs. U.S. Savings Bonds & Treasuries

You could alternatively put your funds in U.S. savings bonds or Treasuries. The U.S. government offers two types of savings bonds: EE bonds and I bonds. EE bonds offer a fixed interest rate that you'll know at the time of making your deposit decision, while I bonds offer a rate that changes every six months based on current inflation levels (hence, the name I bonds). These investments are exceptionally safe, but they do not allow a withdrawal within the first 12 months for any reason.

You can also lend money to the U.S. government by purchasing Treasury bonds. These are called T-bills for durations of four weeks to one year, and Treasury notes for durations of two to 10 years. Treasuries are considered one of the safest investments in the world, but their rates are not always as high as the best CDs or high-yield savings accounts.

Where Are CD Rates Headed in 2024?

CD rates took off in 2023. In 2024, there's no sure answer as to what CD rates will do. CD rates are closely tied to the fed funds rate. In December 2023, the Federal Reserve held interest rates steady, keeping it at a 22-year high for the third meeting in a row. The Fed's December 2023 dot plot shows that no members of the rate-setting committee predict another rate increase in 2024. Instead, expectations are for three rate cuts in 2024, for a total drop of 0.75%. If those rate cuts happen, then CD rates will likely follow suit. Of course, nothing is certain. But in anticipation, CD rates softened at the end of 2023 and the start of 2024, and so there may be more CD rate drops coming.

Frequently Asked Questions

  • What Are the Best CD Rates for 18 Months?

    The best CD rates for an 18-month term will be anything over 5.10%. The best 18-month CD will come with a high rate, low early withdrawal penalty, and low minimum deposit required. Most of the top 18-month CDs have an early withdrawal penalty of 3 to 6 months and a minimum deposit of $500 or more.

  • What if I Need My Money Before the CD Matures?

    When you open a CD, you know the precise date that the funds will be ready for penalty-free withdrawal. But sometimes emergencies crop up, or your financial situation changes. If you find you need to access your money before the CD matures, the good news is that withdrawing it is almost always possible.

    The catch is that doing so before maturity will trigger the institution's early-withdrawal penalty. Each bank and credit union has a policy for how that penalty is calculated, and the most common method is for the bank to keep a certain number of months' worth of interest. For instance, if you break an 18-month CD early, you will typically lose three to six months of the interest you earned.

  • When Is an 18-Month CD a Good Choice?

    An 18-month CD is a suitable option for money you won't need in the coming year or longer. For those with a specific plan for the money, such as a down payment on a house or paying college tuition bills for a child, an 18-month CD might provide just the time frame you need to keep funds safe and reliably earning interest.

    Another appeal of 18-month CDs is to provide one rung of a shortened CD ladder. A CD ladder is a strategy for investing your funds in five CDs of differing terms rather than all at once. For a yearly ladder, you would own a one-year, two-year, three-year, four-year, and five-year CD. But you can also create a shorter ladder, with six-month increments between the CDs (e.g., six-month, 12-month, 18-month, etc.).

  • Are Online Bank CDs Safe?

    Many of the highest deposit rates, whether for CDs, savings accounts, or money market accounts, are offered by online banks. Some of these are online-only banks, meaning they operate solely on the Internet, while others are brick-and-mortar banks with a separate online banking arm. Sometimes the online operations of physical banks even have an entirely different name and brand identity.

    Though you may feel nervous depositing your funds into an Internet bank instead of at a physical branch, online accounts and institutions are just as safe as their more traditional counterparts. That's because FDIC insurance doesn't discriminate—the $250,000 in deposit insurance it provides consumers in case of bank failure applies equally to online and brick-and-mortar banks.

  • Why Do Shorter CDs Sometimes Pay More Than Longer CDs?

    Generally speaking, the shorter the CD term, the lower the interest rate paid by the bank, and vice versa. That's because the bank recognizes you need to be rewarded more substantially the longer you're being asked to leave the money on deposit.

    However, not all institutions use a perfectly linear scale of interest rates that increase with the CD terms. A common strategy is offering one or more promotional CDs that pay a significantly higher interest rate to entice customers to the institution. To limit how long the bank is paying the boosted rate, promotional CDs are often shorter in duration, such as less than two years.

    Another factor is that banks and credit unions decide their CD yields based on where they think the federal funds rate will be in the future. So when it's expected that future interest rates will be lower than today's rates, it's common to see short- or mid-term CDs paying the best rates.

  • How Do You Build a CD Ladder?

    CD ladder enables you to access the higher rates typically offered on 5-year CDs, but with the twist that a portion of your money becomes available every year, rather than every five years. Here's how to do it.

    1. Take the amount of money you want to invest in CDs and divide it by five.
    2. Put one-fifth of the funds into a top-earning 1-year CD, another fifth into a top 2-year CD, another into a 3-year CD, and so forth through a 5-year CD. Let’s say you have $25,000 available. That would give you five CDs of varying lengths, each with a value of $5,000.
    3. When the first CD matures in a year, you take the resulting funds and open a top-rate 5-year CD.
    4. One year later, your initial 2-year CD will mature, and you'll invest those funds into another 5-year CD.
    5. Continue doing this every year with whichever CD is maturing until you end up with a portfolio of five CDs all earning 5-year APYs, but with one of them maturing every 12 months, keeping your money a bit more accessible than if all of it were locked up for a full five years.


  • Can You Lose Money in a CD?

    You can't lose your principal when you deposit it in a CD. But you can lose out on interest in the CD if you withdraw it early. Most CDs come with an early withdrawal penalty (but not all CDs have penalties) so if you take your money out of the account before the term is up, you may pay a price. CDs are federally insured though, so if you're worried about losing money in a CD due to a bank failure, you can rest assured that your money is backed by the FDIC or NCUA up to $250,000 per institution.

How We Find the Best 18-Month CD Rates

Every business day, Investopedia tracks the rate data of more than 200 banks and credit unions that offer CDs to customers nationwide, and determines daily rankings of the top-paying certificates in every major term. To qualify for our lists, the institution must be federally insured (FDIC for banks, NCUA for credit unions), and the CD's minimum initial deposit must not exceed $25,000.

Banks must be available in at least 40 states.
