Money that is invested in an interest bearing account such as a savings account or certificate of deposit earns interest. The rate at which interest is paid varies, but it will be a small percentage of the balance in the account. Rates may be either variable or fixed.
A certificate of deposit, or CD, is an extremely safe investment, earning a guaranteed rate of interest and insured by the Federal Deposit Insurance Corporation, or FDIC, or the National Credit Union Administration. However, dispensing with risk, the guaranteed return and safety also means dispensing with any potential for large reward. CDs earn a comparatively very low rate of return on investments. About the only investment that a CD outperforms in regard to rate of return is a standard passbook savings account or an interest-earning checking account.
