numpy.nper() in Python Last Updated : 28 Nov, 2018 Comments Improve Suggest changes Like Article Like Report numpy.pmt(rate, pmt, pv, fv, when = ‘end’) : This financial function helps user to compute number of periodic payments. Parameters : rate : [scalar or (M, )array] Rate of interest as decimal (not per cent) per period pmt : [scalar or (M, )array] Payment value 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 : Number of periodic payments. 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 # pmt() function import numpy as np ''' Question : how much time would it take to pay-off a loan of $10, 000 at 10 % annual rate of interest, if we had $100 to pay each month ? ''' # rate pmt pv Solution = np.nper(0.1 / 12, -100, 10000) # Here fv = 0 ; Also Default value of fv = 0 print("Solution - No. of periods : % f months" %(Solution)) Output: Solution - No. of periods : 215.905777 months Create Quiz Comment M mohit gupta_omg :) Follow 0 Improve M mohit gupta_omg :) Follow 0 Improve Article Tags : Python Python-numpy Python numpy-Financial Functions Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
