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:
# Python program explaining # ipmt() function import numpy as np ''' Question : monthly payment needed to pay off a $10, 000 loan in 12 years at an annual interest rate of 60 % ''' Solution = np.ipmt(0.6 / 12, 2 * 12, 1 * 12, 10000) # Here fv = 0 ; Also Default value of fv = 0 print("Solution - ipmt value : ", Solution) |
Output:
Solution - ipmt value : 801.4432933339593
