CALC VARS
1: Ú				Total number of payment periods
2: æ				Annual interest rate
3: PV				Present value
4: PMT				Payment amount
5: FV				Future value
6: P/Y				Number of payment periods per year
7: C/Y				Number of compounding periods/year

N, I%, PV, PMT, FV

Ú, æ, PV, PMT, and FV are the five TVM variables. They represent the elements of common financial transactions, as described in the table above. æ 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.
