InterestRate calculates the future value of an investment (q) in the cash flow formula (see CashFlowFunctions). The function result is the interest rate value in case of a future value AFutureValue for an investment of a start value APresentValue (PV), where APayment (PMT) is invested for NPeriods (n).
The APaymentTime parameter determines whether the investment (payment) is an ordinary annuity or an annuity due: ptEndOfPeriod must 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.
