What is an 18-month CD?

With a CD, you agree to leave your money in the account for a set period of time — in this case, 18 months. In return for your commitment to leave the money alone, you receive a higher yield than you would earn in a savings account.

With an 18-month CD, your annual percentage yield (APY) is locked in, so you don’t have to worry about your bank potentially lowering the rate on your account before the term ends.

An 18-month CD can be ideal for setting aside money for short-term goals, such as going on vacation or saving for a car down payment. You can also use an 18-month CD as a rung in a CD ladder.

Here are the top widely available 18-month CD rates. Compare these offers, then calculate how much interest you would earn when your CD matures.

How to find the best 18-month CD rates

An 18-month CD is a low-risk investment, although not all CDs are created alike when it comes to APY. But before you purchase an 18-month CD, it’s important to do some research before committing your funds to one.

Taking the time to find the best CD rate can translate to significantly higher interest earnings. “It’s advised that you shop around when searching for CDs,” says Christopher Stroup, CFP, founder and president of Silicon Beach Financial. “For example, online banks tend to offer much higher rates than traditional brick-and-mortar banks. If you’re okay with an online banking relationship, this could be a great opportunity to lock in a better rate.”

Before opening an 18-month CD, it’s also important to make sure you won’t need access to the money before the CD matures. “When considering 18-month CDs, first understand what this lockup period could mean for your personal finances,” Stroup says. “If this money is meant for a future expense or set aside as your emergency reserve, be careful to read the fine print surrounding early withdrawals and penalties should you need the funds prior to the end of the CD term.”
