In this tutorial you will learn about the c program to calculate simple interest and its application with practical example.
In this tutorial, we will learn to create a C program that Find Simple Interest using C programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C programming topics:
- Basic C programming.
- Operators.
- Basic input/output.
- Basic mathematics calculation.
What Is Simple interest ?
Simple interest is the interest amount given by the bank within a year to consumer or taken by bank from consumer for a particular principal amount of money at some rate of interest. Simple Interest is a method of calculating the interest for a loan/principal amount.
Where:=>
SI = simple interest.
P = principal
R = interest rate (in percentage).
T = time duration (in years).

// Online C compiler to run C program online #include <stdio.h> int main() { float si,p,r,t; // declaring varibales printf("enter principal.\t"); // taking input scanf("%f",&p); printf("enter rate \t"); scanf("%f",&r); printf("enter time in year.\t"); scanf("%f",&t); si=(p*r*t)/100; // caluclating si printf("Simple Intrest=%.2f",si); // printing si. return 0; } |
Output
In the above program, we have first declared and initialized a set variables required in the program.
- si = For calculating si.
- p= for principal.
- r= for rate of interest.
- t= for time interval in a year.
First of all we declare 4 variable si,p,r and t then by prompting user to give principal rate and time . Here in this program we get principal rate and time from user.
After accepting values of principle, rate and time from user , we apply the formula to calculate simple interest is which is si= (principle x rate x time) / 100. and after calculating si we will print the Simple Interest.
Simple Interest is a method used by mostly in Banking and Economic sectors to calculate the interest charges on loans or in saving account by Bank or Economic Sectors.
