GrapeCity.CalcEngine.Functions Namespace / CalcIpmtFunction Class / Evaluate Method / Evaluate(Object[]) Method

The args contains 4 - 6 items: rate, per, nper, pv, [fv], [type].

Rate is the interest rate per period.

Per is the period for which you want to find the interest and must be in the range 1 to nper.

Nper is the total number of payment periods in an annuity.

Pv is the present value, or the lump-sum amount that a series of future payments is worth right now.

Fv is the future value, or a cash balance you want to attain after the last payment is made. If fv is omitted, it is assumed to be 0 (the future value of a loan, for example, is 0).

Type is the number 0 or 1 and indicates when payments are due. If type is omitted, it is assumed to be 0.
