Compound Interest Keys In compound interest calculations, the following keys are used to enter or calculate the values listed below. C-Total number of compounding periods. I-Percent interest per compounding period. K-Present value of a future amount. With a savings account, for example, PV represents what your money is worth today. L-Future value of a present amount.
