12-4 Using the Finance Solver
Performing TVM calculations
1. Launch the Financial Solver as indicated at the 
beginning of this section.
2. Use the arrow keys to highlight the different fields and 
enter the known variables in the TVM calculations, 
pressing the   soft-menu key after entering each 
known value. Be sure that values are entered for at 
least four of the five TVM variables (namely, N, I%YR, 
PV, PMT, and FV).
3. If necessary, enter a different value for P/YR (default 
value is 12, i.e., monthly payments).
4. Press the key   to change the Payment mode (Beg 
or End) as required. 
5. Use the arrow keys to highlight the TVM variable you 
wish to solve for and press the   soft-menu key.
PMT
The periodic payment amount. The 
payments are the same amount each 
period and the TVM calculation assumes 
that no payments are skipped. Payments 
can occur at the beginning or the end of 
each compounding period -- an option 
you control by setting the Payment mode 
to Beg or End.
FV
 The future value of the transaction: the 
amount of the final cash flow or the 
compounded value of the series of 
previous cash flows.  For a loan, this is the 
size of the final balloon payment (beyond 
any regular payment due).  For an 
investment this is the cash value of an 
investment at the end of the investment 
period.
