What is a CD Calculator?
A CD Calculator (Certificate of Deposit Calculator) is a financial tool that helps investors calculate the interest they will earn on a Certificate of Deposit over a fixed period. CDs are time-bound savings accounts that offer a fixed interest rate in exchange for keeping a lump-sum deposit untouched for a set period. A CD calculator can help to project what the investment will be worth at maturity, taking into account variables such as the initial deposit, interest rate, and term length.
