Product overview

This component implements few functions for financial calculation. These functions are available in MS Visual Basic 6 but are missing in VBScript: DDB, FV, IPmt, NPer, Pmt, PPmt, PV, Rate, SLN, SYD. To be honest, three functions of VB6 are not implemented in this component: IRR, MIRR, and NPV. This component can be useful for those developers whose activity is related to a re-implementation of some existing VB application using VBScript or any other scripting technology, including ASP, WSH, and etc.

Features

This component provides few functions that are identical to the original MS Visual Basic functions listed above. The only difference between this component and original functions is a trailing underscore sign "_" in the end of name of each function implemented in this component. For instance, the function DDB_ of this component references to the original DDB function.

Functions

DDB( cost, salvage, life, period [, factor] ) - Returns a Double specifying the depreciation of an asset for a specific time period using the double-declining balance method or some other method you specify

FV( rate, nper, pmt [, pv [, type]] ) - Returns a Double specifying the future value of an annuity based on periodic, fixed payments and a fixed interest rate

IPmt( rate, per, nper, pv [, fv [, type]] ) - Returns a Double specifying the interest payment for a given period of an annuity based on periodic, fixed payments and a fixed interest rate

NPer( rate, pmt, pv [, fv [, type]] ) - Returns a Double specifying the number of periods for an annuity based on periodic, fixed payments and a fixed interest rate

Pmt( rate, nper, pv [, fv [, type]] ) - Returns a Double specifying the payment for an annuity based on periodic, fixed payments and a fixed interest rate

PPmt( rate, per, nper, pv [, fv [, type]] ) - Returns a Double specifying the principal payment for a given period of an annuity based on periodic, fixed payments and a fixed interest rate

PV( rate, nper, pmt [, fv [, type]] ) - Returns a Double specifying the present value of an annuity based on periodic, fixed payments to be paid in the future and a fixed interest rate

Rate( nper, pmt, pv [, fv [, type [, guess]]] ) - Returns a Double specifying the interest rate per period for an annuity

SLN( cost, salvage, life ) - Returns a Double specifying the straight-line depreciation of an asset for a single period

SYD( cost, salvage, life, period ) - Returns a Double specifying the sum-of-years' digits depreciation of an asset for a specified period
