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.

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 to build 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. But before you purchase one, it’s important to know what you’re getting yourself into.

Ask if you’ll have to maintain a certain balance to earn the APY. While you’re at it, find out how often you’ll receive the interest you’re earning from your bank or credit union. That way, it’ll be easier to hit your savings target or another financial goal.

Don’t assume that the best 18-month CD rates are found at your current bank. Instead, compare CDs online.

Finding the best 18-month CD may take some time. Besides the interest rate, you’ll need to compare early withdrawal penalties and minimum deposit requirements. Also, find out whether you’ll be responsible for any fees.
