18-month CD FAQs
How much do you make on an 18-month CD?
The amount of interest you can expect to earn from an 18-month CD depends on how much you deposit, your CD’s interest rate, and how frequently the interest on your CD compounds.
Right now, the most competitive CD rates on the market are as high as 4%. So, say you deposit $1,000 into an 18-month CD at a rate of 4% APY. If interest compounds monthly, you’d earn about $60 in interest by the end of your CD’s term.
Is an 18-month CD a good idea?
An 18-month CD can be a worthwhile investment if you can secure a favorable rate and know you won’t need to access the funds for that period of time. If you have a specific goal and timeline in mind, using a CD to boost your savings can be a smart strategy.

Best 18-month CDs methodology
Our grading system, collected and carefully reviewed by our personal finance experts, comprised over 300 data points for federally insured CDs with 18-month terms. We used this data to develop our list of the best CDs.
We evaluated these accounts according to several key metrics, including annual percentage yield, minimum opening deposit, compounding frequency, and more.
The accounts on our list could earn a maximum of 25 points across all metrics. Here’s a closer look at the categories we considered:
-
Annual percentage yield (APY): Accounts with higher APYs were rewarded with more points than those with lower APYs. Note that rates on our list are current at the time of publishing, but are subject to change at any time.
-
Minimum opening deposit: Many CDs require a minimum deposit to open an account. Accounts with no or low minimum deposit requirements ranked more favorably than those with higher opening deposit requirements.
-
Compounding frequency: Compounding can occur daily, monthly, quarterly, or even annually. We awarded more points to accounts that compound interest frequently.
-
Customer service contact methods: Our team awarded one point for every contact method available to customers (phone, email, chat).
