Time Value of Money solver
This is a solver for problems involving the time value of money (TVM). It emulates the TVM solver on the TI-83+ and TI-84 graphing calculators.
The seven TVM variables are as follows.
N The number of payments
I% The interest rate, as a percentage. It should not be divided by 100.
PV Present value
PMT Periodic payment
FV Future value
P/Y Payments per year
C/Y Times per year that interest is compounded
You must press Enter or Tab after entering a value in the input box, or the value will not be updated. Note that inflows of cash are considered positive and outflows are negative.
This is a preliminary version, and it may have bugs. In particular, solving for I% may give incorrect values if the inputs are extreme.
