The TVM Solver displays the time-value-of-money (TVM) variables. Given four variable
values, the TVM Solver solves for the fifth variable.
The
FINANCE VARS
menu section describes the five TVM variables (
Ú
,
æ
,
PV
,
PMT
, and
FV
) and
P/Y
and
C/Y
.
PMT: END BEGIN
in the TVM Solver corresponds to the
FINANCE CALC
menu items
Pmt_End
(payment at the end of each period) and
Pmt_Bgn
(payment at the beginning of
each period).
To solve for an unknown
TVM
variable, follow these steps.
1. Press
Œ Í Í
to display the TVM Solver. The screen below shows the
default values with the fixed-decimal mode set to two decimal places.
2. Enter the known values for four
TVM
variables.
Note:
Enter cash inflows as positive numbers and cash outflows as negative
numbers.
