24 Time-Value-of-Money and Amortization Worksheets
Entering Values for I/Y, P/Y, and C/Y
• Enter I/Y as the nominal interest rate. The TVM worksheet
automatically converts I/Y to a per period rate based on the values of
P/Y and C/Y .
• Entering a value for P/Y automatically enters the same value for C/Y .
(You can change C/Y .)
Specifying Payments Due With Annuities
Use END / BGN to specify whether the transaction is an ordinary annuity
or an annuity due.
• Set END for ordinary annuities, in which payments occur at the end
of each payment period. (This category includes most loans.)
• Set BGN for annuities due, in which payments occur at the beginning
of each payment period. (This category includes most leases.)
Note: When you select beginning-of-period payments, the BGN indicator
appears. (No indicator appears for END payments.)
Updating P1 and P2
To update P1 and P2 for a next range of payments, press % with P1 or
P2 displayed.
Different Values for BAL and FV
The computed value for BAL following a specified number of payments
might be different than the computed value for FV following the same
number of payments.
• When solving for BAL , PRN , and INT , the calculator uses the PMT
value rounded to the number of decimal places specified by the
decimal format.
• When solving for FV , the calculator uses the unrounded value for
PMT .
Entering, Recalling, and Computing TVM Values
• To enter a TVM value, key in the value and store it by pressing a TVM
key (
,, -, ., /, 0).
• To display a stored TVM value, press J and a TVM key.
You can enter or recall a value for any of the five TVM variables ( N , I/Y ,
PV , PMT , or FV ) in either the standard calculator mode or a worksheet
mode. The information displayed depends on which mode is selected.
• In standard calculator mode, the calculator displays the variable
label, the = sign, and the value entered or recalled.
