Method Detail

fv

public static double fv(double r,
                        double n,
                        double y,
                        double p,
                        boolean t)

Future value of an amount given the number of payments, rate, amount of individual payment, present value and boolean value indicating whether payments are due at the beginning of period (false => payments are due at end of period)

Parameters:

r - rate

n - num of periods

y - pmt per period

p - future value

t - type (true=pmt at end of period, false=pmt at begining of period)

pv

public static double pv(double r,
                        double n,
                        double y,
                        double f,
                        boolean t)

Present value of an amount given the number of future payments, rate, amount of individual payment, future value and boolean value indicating whether payments are due at the beginning of period (false => payments are due at end of period)

Parameters:

r -

n -

y -

f -

t -

npv

public static double npv(double r,
                         double[] cfs)

calculates the Net Present Value of a principal amount given the discount rate and a sequence of cash flows (supplied as an array). If the amounts are income the value should be positive, else if they are payments and not income, the value should be negative.

Parameters:

r -

cfs - cashflow amounts

pmt

public static double pmt(double r,
                         double n,
                         double p,
                         double f,
                         boolean t)

Parameters:

r -

n -

p -

f -

t -

nper

public static double nper(double r,
                          double y,
                          double p,
                          double f,
                          boolean t)

Parameters:

r -

y -

p -
