You will receive both principal and interest at maturity.
CDs are popular among people who like their investments low-risk and straightforward.
Many advisors also consider them to be safe investments suitable for diversifying portfolios. Because your money is expected to stay on deposit until maturity, you may be assessed a penalty if you withdraw your money from it early. Usually, the penalty is three to six month's interest. Banks sell most CDs. Brokerage firms also sell CDs and typically look for ones with the highest rates and make them available to their clients.
