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 :

Example 1: 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.  Example 2: Input: P = 3000        R = 7        T = 1 Output: 210

Recommended PracticeSimple InterestTry It!

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.

Below is the implementation of the above example:

C++

// C++ program to find simple interest  // for given principal amount, time  // and rate of interest. #include<iostream> using namespace std;  // 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 the resultant value of SI      cout << "Simple Interest = " << SI;      return 0; }

Output:

Simple Interest: 0.01

Time complexity: O(1).
Auxiliary space: O(1).
