numpy.ipmt(rate, nper, pv, fv, when = ‘end’)
: This financial function helps user to compute payment value as per the interest only. i.e. returns the interest part.
Parameters :
rate : [scalar or (M, )array] Rate of interest as decimal (not per cent) per period
nper : [scalar or (M, )array] total compounding periods
fv : [scalar or (M, )array] Future value
pv : [scalar or (M, )array] present value
when : at the beginning (when = {‘begin’, 1}) or the end (when = {‘end’, 0}) of each period.Default is {‘end’, 0}
Return : Payment value ie. the interest part of it.
Equation being solved :
fv + pv*(1+rate)**nper + pmt*(1 + rate*when)/rate*((1 + rate)**nper – 1) == 0
or when rate == 0
fv + pv + pmt * nper == 0
Code:
import numpy as np
Solution = np.ipmt( 0.6 / 12 , 2 * 12 , 1 * 12 , 10000 )
print ( "Solution - ipmt value : " , Solution)
|
Output:
Solution - ipmt value : 801.4432933339593
