TVM and Amortization Worksheet Variables
Note: This guidebook categorizes calculator variables by the method of
entry. (See “Types of Worksheet Variables” on page 17.)
Using the TVM and Amortization Variables
Because the calculator stores values assigned to the TVM variables until
you clear or change them, you should not have to perform all steps each
time you work a problem.
• To assign a value to a TVM variable, key in a number and press a TVM
key (,, -, ., /, 0).
• To change the number of payments (
P/Y), press &[, key in a
number, and press !. To change the compounding periods (C/Y),
press &[ #, key in a number, and press !.
• To change the payment period (END/BGN), press & ], and then
press & V.
• To compute a value for the unknown variable, press %, and then
press the key for the unknown variable.
