NumberOfPeriods calculates the number of periods (n) needed to obtain future value of an investment in the cash flow formula (see CashFlowFunctions). The function result is the number of periods a payment APayment (PMT) must be paid in order to obtain a future value AFutureValue for an investment of a start value APresentValue (PV), where APayment (PMT) is invested at a rate ARate (q).
The APaymentTime parameter determines whether the investment (payment) is an ordinary annuity or an annuity due: ptEndOfPeriod NumberOfPeriodsmust be used if payments are at the end of each period. If the payments are at the beginning of the periode, ptStartOfPeriod must be used.
