In summary, to enter the cash flow amounts:

1.Press fCLEARHto clear the financial and storage registers.

2.Key in the amount of the initial investment, press Þ if that cash flow is negative, then press gJ.

3.Key in the amount of the next cash flow, press Þ if the cash flow is negative, then press gK. If the cash flow amount is zero in the next period, press 0 gK.

4.Repeat step 3 for each cash flow until all have been entered.

With the amounts of the cash flows stored in the calculator’s registers, you can calculate NPV as follows:

1.Enter the interest rate, using ¼or gC.

2.Press fl.

The calculated value of NPV appears in the display and also is automatically stored in the PV register.

Example: An investor has an opportunity to buy a duplex for $80,000 and would like a return of at least 13%. He expects to keep the duplex 5 years and then sell it for $130,000; and he anticipates the cash flows shown in the diagram below. Calculate NPV to determine whether the investment would result in a return or a loss.

Note that although a cash flow amount ($4,500) occurs twice, these cash flows are not consecutive. Therefore, these cash flows must be entered using the method described above.
