# Program to find the Depreciation of Value

The value of any article or item subject to wear and tear, decreases with time. This decrease is called its Depreciation. Given three variable **V1**, **R** and **T** where **V1** is the initial value, **R** is the rate of depreciation and **T** is the time in years. The task is to find the value of the item after **T** years.**Examples:**

Input:V1 = 200, R = 10, T = 2Output:162Input:V1 = 560, R = 5, T = 3Output:480.13

**Approach:** As in **Compound Interest**, interest is regularly added to the principal at the end of the agreed intervals of time to generate a new and fresh principal. Similarly, Depreciated value is the decreased value from the amount at the end of agreed intervals of time to generate a new Value.

Thus if **V1** is the value at a certain time and **R%** per annum is the rate (the rate can not be more than 100%) of depreciation per year, then the value **V2** at the end of **T** years is:

Below is the implementation of the above approach :

## C++

`// CPP program to find depreciation of the value` `// initial value, rate and time are given` `#include <bits/stdc++.h>` `using` `namespace` `std;` `// Function to return the depreciation of value` `float` `Depreciation(` `float` `v, ` `float` `r, ` `float` `t)` `{` ` ` `float` `D = v * ` `pow` `((1 - r / 100), t);` ` ` `return` `D;` `}` `// Driver Code` `int` `main()` `{` ` ` `float` `V1 = 200, R = 10, T = 2;` ` ` `cout << Depreciation(V1, R, T);` ` ` `return` `0;` `}` |

## Java

`// Java program to find depreciation of the value` `// initial value, rate and time are given` `import` `java.io.*;` `class` `GFG` `{` `// Function to return the depreciation of value` `static` `float` `Depreciation(` `float` `v,` ` ` `float` `r, ` `float` `t)` `{` ` ` `float` `D = (` `float` `)(v * Math.pow((` `1` `- r / ` `100` `), t));` ` ` `return` `D;` `}` `// Driver code` `public` `static` `void` `main(String[] args)` `{` ` ` `float` `V1 = ` `200` `, R = ` `10` `, T = ` `2` `;` ` ` ` ` `System.out.print(Depreciation(V1, R, T));` `}` `}` `// This code is contributed by anuj_67..` |

## Python3

`# Python 3 program to find depreciation of the value` `# initial value, rate and time are given` `from` `math ` `import` `pow` `# Function to return the depreciation of value` `def` `Depreciation(v, r, t):` ` ` `D ` `=` `v ` `*` `pow` `((` `1` `-` `r ` `/` `100` `), t)` ` ` `return` `D` `# Driver Code` `if` `__name__ ` `=` `=` `'__main__'` `:` ` ` `V1 ` `=` `200` ` ` `R ` `=` `10` ` ` `T ` `=` `2` ` ` `print` `(` `int` `(Depreciation(V1, R, T)))` `# This code is contributed by` `# Surendra_Gangwar` |

## C#

`// C# program to find depreciation of the value` `// initial value, rate and time are given` `using` `System;` `class` `GFG` `{` `// Function to return the depreciation of value` `static` `float` `Depreciation(` `float` `v, ` `float` `r, ` `float` `t)` `{` ` ` `float` `D = (` `float` `) (v * Math.Pow((1 - r / 100), t));` ` ` `return` `D;` `}` `// Driver code` `public` `static` `void` `Main()` `{` ` ` `float` `V1 = 200, R = 10, T = 2;` ` ` ` ` `Console.WriteLine(Depreciation(V1, R, T));` `}` `}` `// This code is contributed by nidhiva` |
