Comments on points, First payment up front, and Last payment up front These entities affect the calculations as follows: Calculation of FV, payment amount, or number of payments is independent of these three Calculation of PV: The number of payments is reduced by 1 for each of the two 'up front' payments. Next, the PV is calculated and then reduced by the amount of the points and 1 payment amount for each of the 'up front' payments. Calculation of I: These amounts are deducted from the PV and the number of payments is reduced by 1 for each of the 'up front' payments. Next, the interest rate is calculated.

public static function getAmt(pv: Number,
 fv: Number,
 i: Number,
 n: Number): Number

getEffectiveRate

public static function getEffectiveRate(pv,
 n,
 a,
 points,
 FirstPmtAtBegin,
 LastPmtAtBegin)

getFV

public static function getFV(pv: Number,

 a: Number): Number

getI

public static function getI(fv: Number,
 pv: Number,
 n: Number,
 a: Number,
 PmtFreq: String): Number

getN

public static function getN(pv: Number,
 fv: Number,
 i: Number,
 a: Number): Number

getPV

public static function getPV(fv: Number,
 i: Number,
 n: Number,
 a: Number): Number

payment

public static function payment(pv: Number,
 i: Number,
 n: Number): Number
Calculates loan repayments Formula: PAY = pv x i / (1 – (1 + i)–n) This formula means that the payment (PAY) is equal to the present value of the loan (pv) multiplied by the interest rate (i) divided by 1 minus 1 plus the interest rate raised at the power of the number of periods (n) To convert to monthly payments use PeriodI(i,"monthly") and years*12

Parameters:
pv
present value or principal amount
i
interest rate
n
number of periods
Returns:
Repayment Installement

PeriodI

public static function PeriodI(i: Number,
 PmtFreq: String): Number

RoundToDigits

public static function RoundToDigits(nbr,
 dig)
returns nbr rounded to dig digits; dig > 0 gives dig decimal places; dig < 0 rounds to the left of the decimal point

slope

public static function slope(fv: Number,
 estI: Number,
 n: Number,
 a: Number): Number
