Expert Advice on Choosing the Best 18-month CD

To learn more about what makes a good CD and how to choose the best fit, four experts weighed in:

PFI Banking Expert Panel that includes: Tania Brown, Roger Ma, Sophia Acevedo, and Mykail James

Insider



Here’s what they had to say about CDs. (Some text may be lightly edited for clarity.)

How can someone determine whether a bank is the right fit for them?

Tania Brown, certified financial planner at SaverLife:

“Obviously, you want to make sure it’s FDIC insured. Also, your banking experience — do you like walking into a bank? Well, then you need someone local. Do you just not care if you ever see your bank? Then you’re okay online. Do you write checks? Do you not write checks? So it’s thinking through how your experience with it is going to be before you make that decision.”

Sophia Acevedo, certified educator in personal finance, banking reporter, Personal Finance Insider:

“I would create a list of what I prioritize most in a bank account. For example, some banks have accounts that charge monthly service fees. I would look to see what the requirements are for waiving the monthly service fee and whether I think I could feasibly meet those requirements each month. If I’m searching for an interest-earning bank account I’ll pay attention to interest rates. I would make sure the account pays a higher interest rate than the average bank account.”

How should someone choose a CD term length?

Roger Ma, certified financial planner with lifelaidout® and author of “Work Your Money, Not Your Life”:

“I would think about when you need the money and then compare that with what the prevailing CD rates are, and then what makes sense from a financial perspective, but also from your own personal timing perspective.”

Mykail James, MBA, certified financial education instructor, BoujieBudgets.com:

“I believe in having a plan for whatever the funds are. If it’s supposed to be a house fund, and you want to wait for another two years to buy a house, that’s what you should be thinking of when you want to have this money.”

How should someone decide whether to put their money in a high-yield savings account, money market account, or CD?

Tania Brown, CFP:

“So I guess we’ll start off with how much money you want to put in and … the level of transactions you want to have. If you want to have any transactions, that automatically takes out CDs. Then you’re stuck between the high-yield savings and the money market account.”

Sophia Acevedo, Personal Finance Insider:

“Generally, I think a high-yield savings account or money market account could be good options for an emergency fund or short-term savings goals. A high-yield savings account offers a higher interest rate than traditional savings accounts at brick-and-mortar banks. Meanwhile, money market accounts might be worth considering if you want more account accessibility — several offer paper checks, ATM cards, or debit cards. CDs could be worthwhile if you don’t need access to some of your money, since they have a fixed interest rate for a specific term.”

Our Methodology

At Personal Finance Insider, our goal is to create helpful reviews, guides, and explainers so that you can make good decisions about your money. We recognize every person has distinct preferences, so we provide ample options to help you find the most suitable financial product or account.

First, we researched to find over two dozen banks and credit unions that offered 18-month CDs. Then, we reviewed each institution to find the most-well rounded banking options. For each account, we compared the minimum opening deposits, early withdrawal penalties, and interest rates. We also considered the overall banking experience at each bank by assessing customer support availability, mobile app ratings, and ethics. Read more about how we rate CDs.

18-month CD Frequently Asked Questions 

An 18-month CD is a type of savings account. You make a one-time deposit and keep money in the account for 18 months. In return, banks offer a fixed interest rate so you can earn a little extra on your savings. You’ll have the option to renew your CD at the end of the 18-month period or close the account and pocket the money.

CDs do not charge monthly service fees, but you may have to pay an early withdrawal penalty if you decide to take out money before the end of your term. You also typically won’t be able to deposit more money before the CD matures.

Traditional CDs lock in your rate for a specific term. Let’s say, for example, you want to open an 18-month CD that pays 5.00% APY.  You’ll earn 5.00% APY for 18 months — the rate won’t fluctuate until your term ends. If you choose the renew your CD after it matures, you’ll earn the new rate that is currently offered by your bank. 

The best rate for an 18-month CD is 6.167% APY. Credit Union One of Oklahoma is paying this rate, but keep in mind that you must live or work in certain parts of Oklahoma to open an account. The next-highest rate is on the Crescent Bank 18 Month CD, which offers 5.20% APY to the general public.

Typically, your choice will likely depend on how soon you plan to need the money.

For example, if you want the money to buy a house in less than a year, a longer term isn’t the best idea. If you don’t need access to your money soon and you’re searching for a low-risk option, a CD might be a worthwhile option.

Many experts recommend CD laddering. With this strategy, you open multiple CDs with different term lengths so you can take advantage of higher rates with longer terms, but also access some of your money earlier. For instance, you might open 6-month, 18-month, and 5-year CDs at the same time, which means you’ll get some of your money back in six months, then more in 18 months, then more in five years.

Choosing between an 18-month CD or a high-yield savings account may ultimately depend on your goals and preferences.

You may prefer a high-yield saving account over a CD if you want quick access to your money. If you need access to money from your 18-month CD before it matures, then you’ll usually have to pay a fee. In comparison, you should be able to access funds from your savings account regularly.

A CD also locks in your rate for the entire term. If rates are dropping, this could make the CD a better choice, because the interest rate on your saving account could decrease over the next few months. If rates are rising, the savings account might be a better fit, because your rate could go up. Either way, there’s a good chance rates will fluctuate over an 18-month period.

Like with a high-yield savings account, you may prefer a money market account over a CD if you want quick access to your money. Money market accounts often come with debit cards or paper checks so you can use your account for spending. With a traditional CD, you usually face a penalty if you want to take out money from an account before the end of its term.

Money market account rates also fluctuate, so you may prefer a money market account if rates are rising, but a CD if rates are dropping. Still, remember that rates will likely go up or down over a 6-month term.

CDs are generally viewed as a savings account. CDs are a low-risk option since you’re guaranteed fixed returns as long as you keep your money in an account for an entire time. Your potential gains, however, are limited.

If you’re comfortable parting with your money for longer and want to take more risk with your money, then you may want to invest in the stock market. One way to do this is through tax-advantaged retirement accounts, like a 401(k) or IRA, which grows your money over decades. Another is through brokerage accounts, which are useful tools to build long-term wealth, but can’t guarantee a given return like a CD can.

Bank Trustworthiness and BBB Ratings

We’ve compared each company’s Better Business Bureau score. The BBB grades businesses based on factors like responses to customer complaints, honesty in advertising, and transparency about business practices. Here is each company’s score:

Credit Union One of Oklahoma has an NR (No Rating) because the BBB doesn’t have enough information to give it a score yet. CFG Bank currently doesn’t have a rating because its profile is being updated on the BBB website. Ally received an A rating from the Better Business Bureau because it has a few unresolved customer complaints.

The BBB gave CIBC Bank USA an A+ rating. However, its parent company CIBC has an F rating because the BBB has received numerous complaints, and the bank hasn’t responded to or resolved some complaints. 

A good BBB rating doesn’t necessarily mean that your relationship with the bank will be perfect. Talk to current customers or read online customer reviews to get a more well-rounded perspective about whether the bank may be ideal for you.

CIBC Bank has been involved in a recent public controversy. In 2021, CIBC agreed to pay $125 million in a settlement when accused of misrepresenting financial information regarding CIBC investments and US residential mortgage-backed securities.
