- Java program to find the Compound interest.

In this java program to calculate compound interest, we first take amount, rate of interest and duration in year as input from user and use following equation to calculate compound interest.

**How to Calculate Compound Interest ?**

Amount = P x (1 + R/100)T

Compound Interest = Amount - P

Where P, R and T are Principle, Rate of Interest and Time respectively.

## Java program to calculate compound interest

package com.tcc.java.programs; import java.util.Scanner; /** * Java Program to calculate Compound Interest */ class CompoundInterest { public static void main(String[] args) { double principal, time, rate, CI; Scanner scanner = new Scanner(System.in); // Taking input from user System.out.println("Enter Amount"); principal = scanner.nextDouble(); System.out.println("Enter Duration in Years"); time = scanner.nextDouble(); System.out.println("Enter Rate of Interest"); rate = scanner.nextDouble(); // Calculate Compound Interest CI = principal * Math.pow(1.0 + rate / 100.0, time) - principal; System.out.format("Compound Interest = %f", CI); } }Output

Enter Amount 10000 Enter Duration in Years 3 Enter Rate of Interest 10 Compound Interest = 3310.000000
