# C Program To Find Simple Interest

What is ‘Simple Interest’?
Simple interest is a quick method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Simple Interest formula:

Simple interest formula is given by:
Simple Interest = (P x T x R)/100
Where,
P is the principal amount
T is the time and
R is the rate

Examples :

```EXAMPLE1:
Input: P = 10000
R = 5
T = 5
Output: 2500
We need to find simple interest on
Rs. 10,000 at the rate of 5% for 5
units of time.

EXAMPLE2:
Input: P = 3000
R = 7
T = 1
Output: 210```

The formula to calculate the simple interest is: simple_interest = (P * T * R) / 100 where P is the principal amount, T is time & R is the rate of interest.

## C

 `// C program to implement``// the above approach``#include ` `// Driver code``int` `main()``{``    ``// We can change values here for``    ``// different inputs``    ``float` `P = 1, R = 1, T = 1;` `    ``// Calculate simple interest``    ``float` `SI = (P * T * R) / 100;` `    ``// Print Simple Interest``    ``printf``(``"Simple Interest = %f\n"``, SI);` `    ``return` `0;``}` `// This code is contributed by agarwalsajal19.`

Output

```Simple Interest = 0.010000
```
