PRODUCT INFORMATION

18 Month CDs - Online Banks 2021

Eighteen-month CDs are offered by many online banks. They are a medium-term CD product that often provide a slightly higher yield than a 12-month CD in return for the extra six months of commitment to keep the money on deposit at the issuing bank. All eighteen-month CDs offered by online banks on BestCashCow are FDIC insured.

Opening an eighteen-month CD online is an easy process. Applications generally take between 10-15 minutes to complete. Funding the CD can usually be done electronically by making a ACH transfer from a checking or savings account to the bank opening the CD. The CD rate is usually locked once the application has been received and approved. Funds transfers can take between 1-5 days depending on the process used by the opening bank.

In some cases, branch-based banks and credit unions will offer higher rates on 18-month CDs than online banks. You should check the rates available in your area using the tabs above.

Jumbo CDs refer to those CDs with minimum deposits of $100,000. While some banks still reserve their best CD rates for those customers opening jumbo products with deposits of $100,000 or more, the table above indicates that many online banks now offer their highest yielding CD rates to those depositing much less.

The advantages of an eighteen month online CD are:

  • 18-month CDs offer a higher rate than 12-month CDs in return for leaving the money in the bank longer.
  • A fixed rate during the 18 month period.
  • FDIC insurance.
  • Convenience of opening and managing the CD without needed to visit a local branch.

The disadvantages of an eighteen month online CD are:

  • Rates are generally not significantly higher than the top online savings and money market accounts, and may not compensate you adequately for your loss of liquidity.
  • Money is tied up for 18 months. It may not always be possible to remove your money early, and, where possible, removing it early may result in penalties and the penalties may be significant (including a loss of principal).

All banks listed on BestCashCow are FDIC insured; BestCashCow.com strongly recommends that you stay within FDIC insurance limits and that if you are unsure of how the limits affect you, please visit the FDIC website.
