# Write a Python Program to Calculate Compound Interest

In this tutorial, we will discuss Write a Python Program to Calculate Compound Interest and this python program we are going to learn the concept of Calculate Compound Interest in the python language. ## Python Program to Calculate Compound Interest.

Let’s begin by writing a Python program to determine compound interest. In the below example, we have provided both future-value (the principal + interest accumulated) and the number of years as arguments.

let me show you the formula behind this Compound Interest:

Future CI = Principal Amount * ( 1 + ROI ) Number of years)

``````import math

princ_amount = float(input(" Please Enter the Principal Amount : "))
rate_of_int = float(input(" Please Enter the Rate Of Interest   : "))
time_period = float(input(" Please Enter Time period in Years   : "))

ci_future = princ_amount * (math.pow((1 + rate_of_int / 100), time_period))
compound_int = ci_future - princ_amount

print("Future Compound Interest for Principal Amount {0} = {1}".format(princ_amount, ci_future))
print("Compound Interest for Principal Amount {0} = {1}".format(princ_amount, compound_int))``````

Here the OutPut of this program.

``````Please Enter the Principal Amount : 600
Please Enter the Rate Of Interest   : 5
Please Enter Time period in Years   : 5
Future Compound Interest for Principal Amount 600.0 = 765.7689375000002
Compound Interest for Principal Amount 600.0 = 165.76893750000022``````
