Hello Friends,

In this blog, I will show you how to calculate simple interest using python. I am going learn you python find simple interest example. We will talk about find simple interest in python.

We will use the simple interest formula Si = (P * R * T)/100 where P is the principle amount, R is the rate of interest, and T is the time period.

Here i will give you two example for how to calculate simple interest using python So let's see below example:

Formula

• P is the principle amount
• T is the time and
• R is the rate

```si = (P x T x R)/100
```

Example 1 :

```# Python program to find simple interest
p = input("Enter Principal: ")
t = input("Enter Time Period: ")
r = input("Enter Rate Of Interest: ")

# find simple interest
si = (p * t * r)/100

print('The Simple Interest is', si)
```

Example 2 :

```# Python program to find simple interest

def findSimpleInterest(p,t,r):
print('The principal is', p)
print('The time period is', t)
print('The rate of interest is',r)

si = (p * t * r)/100

print('The Simple Interest is', si)
return si

findSimpleInterest(8, 6, 8)
```
