numpy.fv(rate, nper, pmt, pv, when = 'end') : This financial function helps user to compute future values.
Parameters :
Python
Output :
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 periodsEquation being solved :
fv + pv*(1+rate)**nper + pmt*(1 + rate*when)/rate*((1 + rate)**nper - 1) == 0or when rate == 0
fv + pv + pmt * nper == 0Code 1 : Working

Assume the interest rate is 5% (annually)
compounded monthly ?
