Let's try a sample problem. Suppose you deposit $$100$ in an account with an annual interest rate of $6\%.$ What is the future value of this $$100$ in five years?

Enter the data into your calculator:

N $=5$

I$/$Y $=6$

PV $=-100$

PMT $=0$

Solve for FV by pressing CPT FV$.$

FV $=$

Notice two things about this calculation:

$1.$ You enter the PV as $-100\mathrm{.}00.$ The calculator distinguishes which direction the cash flows move. You began by taking $$100$ out of your pocket today $($negative cash flow$)$ and invested it so you can put money back in your pocket five years from now $($positive cash flow$).$ Different signs reflect different directions that the cash flows are traveling.

$2.$ You enter the interest rate as a whole number $(6),$ not as a decimal $(0\mathrm{.}06)$
