An 18-month CD bridges the gap between short-term flexibility and longer-term yields. It locks in a competitive rate for a year and a half — ideal for savers who want more than a 12-month commitment without tying up funds for two or more years. We display Safety Grades, Star Ratings, and Texas Ratios so you can choose institutions with confidence.
The APYs displayed reflect actual verified offers. Rates are subject to change at the institution’s discretion without notice. A substantial penalty may be imposed for early withdrawal. 18-Month CD Rates Last Updated and Verified: October 12, 2026

How to Find the Best 18-Month CD Rates
What to compare when shopping for an 18-month CD
To find the best APYs on an 18-month CD, start with credit unions and online-only banks — they consistently offer the highest yields because they have lower overhead than traditional brick-and-mortar banks and compete aggressively for deposits.
Always compare the APY (Annual Percentage Yield), not just the interest rate. The APY reflects compounding and is the true measure of what you’ll earn. A CD advertised at 4.75% interest compounding monthly is worth more than one at 4.80% compounding annually.
Also compare the early withdrawal penalty. On a 18-month CD, common penalties range from 30 to 90 days of interest. If you’re unsure whether you’ll need the funds early, a penalty-free no-penalty CD or a high-yield savings account may be a better fit.
When an 18-Month CD Makes Sense
- You have a planned purchase or expense in ~18 months and want to earn while you wait
- You expect interest rates to fall and want to lock in today’s rate short-term
- You want a mid-range commitment — the 18-month term earns more than a 1-year CD while maturing before a 2-year term
- You want FDIC/NCUA protection with a guaranteed fixed return
Consider an Alternative If…
- You may need funds before 3 months → High-yield savings
- Rates are rising and you want to benefit → Variable-rate savings or MMA
- You want check-writing or debit access → Money market account
