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 as high as 1.00% APY, almost triple the average 18-month CD rate of 0.36%. 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.

4. Lafayette Federal Credit Union — 0.75% APY, $50 minimum deposit

The $50 minimum deposit on Lafayette Federal Credit Union’s 18-month certificate is tempting, but keep in mind that it’s a variable rate, which means the certificate rate is subject to change without notice. You can also make additional deposits into the certificate at any time. Dividends are compounded and paid quarterly, and the certificate automatically renews upon maturity. Withdrawing money early will cost you 180 days’ dividends.

Membership to Lafayette Federal Credit Union is open to people who live, work or attend school in the Maryland, Virginia and Washington, D.C. area, but if you live elsewhere in the country, you’re also eligible for membership by joining the Home Ownership Financial Literacy Council, which will only set you back $10.

5. NexBank — 0.75% APY, $10,000 minimum deposit

NexBank’s 18-month certificate of deposit earns you this high rate, but you’ll need to part with a minimum of $10,000.

They may impose a substantial penalty for money withdrawn before then.

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.
