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 (page 14.14) describes the
five
TVM variables (Ú
ÚÚ
Ú, æ
ææ
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 y [FINANCE] 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.
3. Enter a value for P/Y, which automatically enters the same
value for
C/Y; if P/Y ƒ C/Y, enter a unique value for C/Y.
4. Select END or BEGIN to specify the payment method.
5. Place the cursor on the TVM variable for which you want to
solve.
6. Press ƒ [
SOLVE]. The answer is computed, displayed in
the
TVM Solver, and stored to the appropriate TVM variable.
An indicator square in the left column designates the solution
variable.
