Sometimes you need a shorter-term CD, but the rate of return on a 12-month CD just isn’t quite enough. Thankfully, many institutions offer 18-month CD or 19-month CD options. They typically have higher rates than a 12-month account, while remaining a viable choice for near-term savings goals when a 24-month CD would be too long a commitment.

The key is to find the right 18-month CD to maximize your savings. If you look around, you can find rates just around 1.10% APY, compared to the average 18-month CD rate of 0.58%. To make the search process easier for you, we’ve uncovered the best 18-month CDs using data from DepositAccounts.com to find the highest APY. We also took each account’s minimum deposit requirement into consideration.

The 10 best 18-month CD rates in August 2020

1. Pen Air Federal Credit Union — 1.05% APY, $500 minimum deposit

You’ll need at least $500 to open an 18-month Pen Air Certificate. Then you can start earning at its 1.05% APY. The early withdrawal penalty for this term will equal 180 days’ dividends.

Founded in 1936, Pen Air Federal Credit Union is based in Pensacola, Fla., and maintains locations in Northwest Florida and Southeast Alabama. Pen Air membership is open to you if you’re active duty or retired military, a civil service employee, an employee at a partnering Select Employer Group or an immediate family member of eligible members.

2. CommunityWide Federal Credit Union — 1.10% APY, $1,000 minimum deposit

Open a CommunityWide Federal Credit Union term share certificate with at least $1,000 to start saving at its competitive rate. Note that CW does not automatically renew your certificate at maturity, leaving that choice up to you. CW calculates its early withdrawal penalty a little differently than other institutions. It will equal the amount of the withdrawal times the remaining term (in days) of the certificate at the rate of two times the certificate’s current APR (divided by 365). The penalty will be deducted from the amount withdrawn.

CommunityWide FCU was founded in 1967 as the West Washington Association Federal Credit Union, gaining its current name in 1985. You can join CW if you’re a member, employee or retiree of select organizations, a spouse of someone who died while a member or an immediate family member of qualified members.

7. Primary Bank — 1.00% APY, no minimum deposit

There are no minimum balance requirements on Primary Bank’s 18-month CD, but you may incur a penalty if you withdraw your money early, as is the case with all CDs. If you’re not sure you can commit to parting with that money for 18 months, you could consider one of the bank’s shorter terms of 12 or 15 months, which will still earn you an APY that would just miss this list by a few spots.

Primary Bank was founded in New Hampshire as a means of supporting small- and medium-sized businesses, but it also offers plenty of personal banking products.

Is it worth getting an 18-month CD over a 1-year CD?

When we discuss CD rates, we tend to center the conversation on 1-year CDs. They’re helpful to look at when assessing changes in rates over time, typically compared to long-term CDs. They also the general starting point when creating a CD ladder. So where do the slightly longer 18-month CDs fit in?

18-month CDs are only six months longer than 1-year CDs. It might seem like too little of a difference, especially when you’re squirreling away cash. However, because of this extra time a bank gets to hold your money, banks are willing to pay higher rates on your 18-month deposits, thus boosting your savings a little bit more.

Let’s say you deposit $1,000 into a bank’s 3% APY 18-month CD. At maturity, you’ll have earned around $46. Making that same deposit into the same bank’s 1-year CD at 2% APY, would earn just a little over $20. Of course, rates vary from bank to bank. That’s why it’s important to look for the best CD rates for each term to make locking your money away more worthwhile.
