InterestRate function

Declaration

function InterestRate(NPeriods: Integer; APayment: Float; 
 APresentValue: Float; AFutureValue: Float; 
 APaymentTime: TPaymentTime): Float

Description

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.
