1: ÚTotal number of payment periods
2: æAnnual 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
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 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.
