Given principle amount, rate and time and we have to find the compound interest in Python.

Calculate compound interest

To calculate compound interest, we use the following formula,

    P(1 + R / 100)T

Where,

  • P – Principle amount
  • R – Rate of the interest, and
  • T – Time in the years

Example:

    Input:
    p = 250000
    r = 36
    t = 1

    # formula
    ci =  p * (pow((1 + r / 100), t)) 
    print(ci)

    Output:
    339999.99999999994

Python program to find compound interest

# Python program to find compound interest 

p = float(input("Enter the principle amount : "))
r = float(input("Enter the rate of interest : "))
t = float(input("Enter the time in the years: "))

# calculating compound interest
ci =  p * (pow((1 + r / 100), t)) 

# printing the values
print("Principle amount  : ", p)
print("Interest rate     : ", r)
print("Time in years     : ", t)
print("compound Interest : ", ci)

Output

First run:
Enter the principle amount : 10000
Enter the rate of interest : 3.5
Enter the time in the years: 1
Principle amount  :  10000.0
Interest rate     :  3.5
Time in years     :  1.0
compound Interest :  10350.0

Second run:
Enter the principle amount : 250000
Enter the rate of interest : 36
Enter the time in the years: 1
Principle amount  :  250000.0
Interest rate     :  36.0
Time in years     :  1.0
compound Interest :  339999.99999999994
