numpy.fv() in Python

Last Updated : 29 Nov, 2018

numpy.fv(rate, nper, pmt, pv, when = 'end') : This financial function helps user to compute future values. Parameters :

rate : [scalar or (M, )array] Rate of interest as decimal (not per cent) per period nper : [scalar or (M, )array] total compounding periods pmt : [scalar or (M, )array] fixed payment 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 :

 value at the end of nper periods

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 1 : Working

Python

# Python program explaining fv() function import numpy as np ''' Question :  Future value after 10 years of saving $100 now,  with an additional monthly savings of $100.  Assume the interest rate is 5% (annually)  compounded monthly ? ''' # rate np pmt pv Solution = np.fv(0.05/12, 10*12, -100, -100) print("Solution : ", Solution)

Output :

 Solution : 15692.9288943
