certificate of deposit (CD)

n. a document issued by a bank in return for a deposit of money which pays a fixed interest rate for a specified period (from a month to several years). Interest rates on CD's are usually higher than savings accounts because banking institutions require a commitment to leave money in the CD for a fixed period of time. Often there is a financial penalty (fee) for cashing in a CD before the pledged time runs out.
