numpy.ipmt() in Python Last Updated : 29 Nov, 2018 Comments Improve Suggest changes Like Article Like Report 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: Python3 1== # 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 Comment More infoAdvertise with us Next Article numpy.ipmt() in Python mohit gupta_omg :) Follow Improve Article Tags : Python Python-numpy Python numpy-Financial Functions Practice Tags : python Similar Reads numpy.i0() function | Python numpy.i0() function is the modified Bessel function of the first kind, order 0. it's usually denoted by I0.
