3: Cash Flow Worksheet 71
Example: Compute Net Present Value of Cash Flows
The cash flows for the first four months are stated as a group of
four $0 cash flows. Because the lease specifies beginning-of-
period payments, you must treat the first cash flow in this
group as the initial investment (
CFo
) and enter the remaining
three cash flows on the cash flow screens (
C01
and
F01
).
Note:
The BGN/END setting in the TVM worksheet does not affect the
Cash Flow worksheet.
Net present value (NPV) = ?
Interest (I) = 10%
C01 C02 C03 C04 C05 C06
$0 $5000 $0 $6000 $0 $7000
F01 = 3 F02 = 8 F03 = 3 F04 = 9 F05 = 2 F06 = 10
Initial investment (CFo) = $0
