numpy.mirr() function

The mirr() function is used to modify internal rate of return.

Syntax:

numpy.mirr(values, finance_rate, reinvest_rate)

Version: 1.15.0

Parameter:

Name	Description	Required / Optional
values	Cash flows (must contain at least one positive and one negative value) or nan is returned. The first value is considered a sunk cost at time zero. array_like	Required
finance_rate	Interest rate paid on the cash flows scalar	Required
reinvest_rate	Interest rate received on the cash flows upon reinvestment scalar	Required

Modified internal rate of return

NumPy.mirr() method Example:

If you investment $1000 and withdrawals at regular interval $100, $50, $10 and $15. Here finance_rate .34 and reinvest_rate .21, Then the calculate modified internal rate of return (mirr)?

>>> import numpy as np
>>> np.mirr([-1000, 100, 50, 10, 15], .34, .21)

Output:

-0.2742274708267268
