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

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.
