Usage at a Glance

• The discount rate is stated as a decimal percent. For example, 10% is stated as 0.1.

• valueArray is a one-dimensional array that must contain at least one negative

value (a payment) and one positive value (a receipt).

• The

NPV investment begins one period before the date of the first cash-flow value

and ends with the last cash-flow value in the array.

•

NPV requires future cash flows. If the first cash-flow occurs at the beginning of the

first period, the first value must be added to the value returned by

NPV and must

not be included in

valueArray.

• NPV is like the PV function, except that PV allows cash flows to begin either at the

beginning or the end of a period and requires that cash flows be fixed throughout

the investment.
