Here in this program, we will calculate Compound Interest using the formula: CI = p(1+r/100) t Here CI = compound interest p= principal r= rate t= time

## C++ Program to Calculate Compound Interest

``````#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 Program to Calculate Compound Interest

``````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``````
