Write a Program in C++ & Python to Calculate Compound Interest

By | July 2, 2019

Here in this program, we will calculate the compound interest using the formula:

CI = p(1+r/100)t

Here

CI = compound interest
p= principal
r= rate
t= time

C++:

#include<iostream.h>
#include< conio.h>
#include<math.h>
void main()
{
clrscr();
float CI,p,r,t;
cout<<"Enter the Principal value: ";
cin>>p;
cout<<"Enter the rate value: ";
cin>>r;
cout<<"Enter the time: ";
cin>>t;
CI = p*pow((1+(r/100)),t);
cout<<"The compound interest is: "<<CI;
getch();
}

Output:

Enter the Principal value: 30000
Enter the rate value: 20
Enter the time: 10
The compound interest is: 185752.0926719999

Python

p = float(input("Enter the Principal value: "))
r= float(input("Enter the rate value: "))
t= float(input("Enter the time: "))
CI =p*((1+(r/100))**t)
print("The compound interest is:",CI)

Output:

Enter the Principal value: 20000
Enter the rate value: 3
Enter the time: 4
The compound interest is: 22510.1762
