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 at or a bit under 1.00% APY, double the average 18-month CD rate of 0.43%. 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.

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.
