Add-On Certificate of Deposit(redirected from Add-On CDs)
Add-On Certificate of Deposit
Money deposited into a certificate of deposit after the initial deposit. Suppose one places $1,000 in a certificate of deposit and places a further $500 into the same account later. One refers to the $500 as an add-on. Only some financial institutions allow add-on certificates of deposit because they receive the same interest rate as the previous deposit, a fact that would be disadvantageous to the financial institution when interest rates are declining.
