To access the TVM variables, follow these steps.

1. Select the Finance icon and press =.

2. Press right arrow key › to VARS. Note: the list of available VARS is listed:

N, I%, PV, PMT, FV

N, I%, PV, PMT, and FV are the five TVM variables. They represent the elements of common financial transactions, as described in the table above. I% is an annual interest rate that is converted to a per-period rate based on the values of P/Y and C/Y.

P/Y and C/Y

P/Y is the number of payment periods per year in a financial transaction.

C/Y is the number of compounding periods per year in the same transaction.

When you store a value to P/Y, the value for C/Y automatically changes to the same value. To store a unique value to C/Y, you must store the value to C/Y after you have stored a value to P/Y.
