Discover offers consumers an IRA certificate of deposit that allows them to grow their balance with high APYs until the account reaches maturity. It is possible to open the CD as a Roth IRA or a Traditional IRA, which changes the customer's tax responsibilities. With a Discover IRA CD, customers can roll over balances or transfer IRAs from other banks. APY rates vary by account term length. There is minimum deposit requirement to open an account.

Discover Financial Services is accredited and rated A+ by the Better Business Bureau. On Trustpilot.com, they hold a middling 6 out of 10 rating, while the Consumer Financial Protection Board has logged over 6,000 complaints—mostly related to their credit card business. However, seeing as Discover is one of the principal financial companies in the United States, this high number of complaints is to be expected. On the financial side, Discover holds strong credit ratings from three of the major credit bureaus, which indicates they are in a stable position to continue meeting their obligations and rendering services.
