Example:
Tom's account begins with \$500, and earns 6% per year, compounded monthly. He deposits an additional \$50 at the end of each month. What will the balance be at the end of one year?

The variables are:
 N = 12 I = 6/12 = 0.5 PMT = 50 increasing PV = 500 FV = ???

To begin, the keystrokes are:
2nd MATH MORE
Press the F key corresponding to the program FIN
Press the F key corresponding to TVM
Then for each variable, enter the following value and press ENTER:
N = 12
I% = 6
PV = 500
PMT = 50
FV =
Then press the F key corresponding to FORMT, enter the following, and press ENTER:
P/Y = 12
If END is not highlighted, move the cursor to END and press ENTER.  Then press the F1 key (TVM), move the cursor to FV, and press F5 (to SOLVE).

The answer is \$1,147.62, rounded to the nearest cent.
