# numpy.pmt () in Python

` numpy.pmt (rate, nper, pv, fv, when = & # 39; end & # 39;) `: this financial function helps the user to calculate the payment amount in principal and percentage.

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

Solving the equation:

fv + pv * (1 + rate) ** nper + pmt * (1 + rate * when) / rate * ((1 + rate) ** nper – 1) == 0

or when rate == 0
fv + pv + pmt * nper == 0
