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 = ???

The keystrokes are:

2nd FIN
12 N
0.5 %i
50 +/- PMT
500 PV
CPT FV

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