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 (

•

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.
