RangeNPV - script function

RangeNPV() returns the net present value of an investment based on a discount rate and a series of future payments (negative values) and incomes (positive values). The result has a default number format of money.

For cash flows that are not necessarily periodic, see RangeXNPV - script function.

Syntax:  

RangeNPV(discount_rate, value[,value][, Expression]) 

Return data type: numeric

Arguments:

• value: A payment or income occurring at the end of each period. Each value may be a single value or a range of values as returned by an inter-record function with a third optional parameter.
• Expression: Optional expressions or fields containing the range of data to be measured.

Limitations:  

Text values, NULL values and missing values are disregarded.

Example 1:  

RangeNPV(0.1,-10000,3000,4200,6800) returns 1188.44.

Example 2:  

Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in your document to see the result.

RangeTab3:

LOAD *,

recno() as RangeID,

RangeNPV(Field1,Field2,Field3) as RangeNPV;

LOAD * INLINE [
