|||A certificate of deposit is a promissory note issued by a bank. It is a time deposit that restricts holders from withdrawing funds on demand. Although it is still possible to withdraw the money, this action will often incur a penalty. For example, let's say that you purchase a $10,000 CD with an interest rate of 5% compounded annually and a term of one year. At year's end,  the CD will have grown to $10,500 ($10,000 * 1.05).CDs of less than $100,000 are called "small CDs"; CDs for more than $100,000 are called "large CDs" or "jumbo CDs". Almost all large CDs, as well as some small CDs, are negotiable.
