CD Calculator Definitions

Initial CD deposit
The starting balance for your certificate of deposit (CD) account.
CD Term
The total number of years for this certificate of deposit (CD) to mature.
Interest rate (CD Rate)
The CD interest rate on your CD. This field is for the actual CD rate, not Annual Percentage Yield (APY).
Annual percentage yield (APY)
This is the effective annual interest rate earned for this CD. The CD's APY is determined on the frequency of compounding and the CD rate. Since APY measures your actual CD interest earned per year, you can use it to compare CD's of different interest rates and compounding frequencies.
Compounding (Interest Compounding)
Interest earned on your accumulated interest. This CD calculator allows you to choose the frequency that your CD's interest income is added to your account. The more frequently this occurs, the sooner your accumulated interest income will generate additional interest. You may wish to check with your financial institution to find out how often interest is being compounded on your particular CD.
