This is a module of compound interest factors which includes single payment, uniform payment series, and arithmetic gradient calculations

By Zaafirrahman

Installation

This library can be installed by the pip command, open your terminal and type in the following command...

pip install compoundinterest

Functions of this library

First import the library using this command

import compoundinterest as ci

and then proceed to call the functions

Single Payment

ci.fp()

This function can be used to calculate compound interest factor of future value based on present value

ci.pf()

This function can be used to calculate compound interest factor of present value based on future value

Uniform Payment Series

ci.fa()

This function can be used to calculate compound interest factor of future value based on annual value

ci.af()

This function can be used to calculate compound interest factor of annual value based on future value

ci.pa()

This function can be used to calculate compound interest factor of present value based on annual value

ci.ap()

This function can be used to calculate compound interest factor of annual value based on present value

Arithmetic Gradient

ci.pg()

This function can be used to calculate compound interest factor of present value based on gradient value

ci.ag()

This function can be used to calculate compound interest factor of annual value based on gradient value

The parameters

i (interest rate) - Interest rate (without percent) used in the calculation

n (time period) - Investment time period (in year/s) used in the calculation

Example :

You are saving $ 30,000 USD in the bank at an interest rate of 10% annually. How much will it be worth when you take it in 5 years?

In this case, the variables that you already know are present value ($ 30,000 USD), interest rate (10%), and investment period (5 years). Whereas the variable that you are looking for is the future value. So you will need the ci.fp() function with the following calculations:

>>> import compoundinterest as ci
>>> ci.fp(10,5)*30000

48315.30000000002

So, your money in the next 5 years is $ 48,315.3 USD
