In this post, we are going to make a Python Program to Calculate Simple Interest and Compound Interest. To make this program, we need three variables "Principle", "Rate", "Time".

We will use the following basic formulas of mathematics to make Python Program to Calculate Simple Interest and Compound Interest.

- Simple Interest = (Principle * Rate * Time) / 100
- Amount = Principle * (1 + Rate / 100)^Time.
- Compound Interest = Amount - Principle

## Python Program to Calculate Simple Interest and Compound Interest

Principle = float(input("Enter Principle:")) Rate = float(input("Enter Rate:")) Time = float(input("Enter Time(n Years):")) Simple_interest = (Principle * Rate * Time) / 100 Amount = Principle * (pow((1 + Rate / 100), Time)) Compound_interest = Amount - Principle print("Simple Interest:", Simple_interest) print("Compound Interest:", Compound_interest)

Output:

Principle:8000

Rate:7

Time(n Years):2

Simple Interest: 1120.0

Compound Interest: 1159.2000000000007

However, This is a very simple python program for beginners. On the other hand, You should also try to make a menu-driven program in python using a while loop for a simple calculator.

It is also an important program for class 11th students. In addition, we can make this program using functions.

## Python Program for Simple Interest using Functions

def Simple_interest(P, R, T): SI = (P * R * T) / 100 print("Simple Interest:", SI) Principle = float(input("Enter Principle:")) Rate = float(input("Enter Rate:")) Time = float(input("Enter Time(n Years):")) Simple_interest(Principle, Rate, Time)

Output:

Principle:9000

Rate:2

Time(n Years):2

Simple Interest: 360.0

## Algorithm to Calculate Simple Interest

- Take input from the user for principle, rate, and time.
- Now, we know the formula to calculate simple interest: Simple Interest = (Principle * Rate * Time) / 100
- Print the simple interest.

## Quick Algorithm to Calculate Compound Interest

- Assign the formula for the amount i.e., Amount = Principle * (1 + Rate / 100)^Time.
- Print "Amount - Principle", which is compound interest.
