### How to work out percentage differences - Step by Step

To find the percent difference between two values x and y, use this formula:

 % difference = |x - y| Ã— 100% (|x| + |y|)/2

Where: x and y are two values of a give variable. Note that percent difference is not equivalent or equal to percent change. Percent change is used when comparing a new value to an old value where the old value is used as a reference. Percent difference is used just to compare two values without considering any order. It doesn't matter which of the two values is written first. That is why the absolute value(*) is often used. Percent difference is also called relative percent difference.

(*) Note: absolute value means that we must consider always a positive value as for example: |1|=1 (absolute value of 1 is 1) and |-1|= 1 (absolute value of minus 1 is also 1). See more about percent difference here.

Here are the solutions to the questions stated above:

### 1) What is the percentage difference between 3 and 39?

Use the above formula to find the percent difference between two numbers. So, replacing the given values, we have the percent difference equation

% Difference
= [(|39| - |3|) / (|3| + |39|)/2] x 100
= [(39 - 3) / (3 + 39) / 2] x 100
= [36 / 42 / 2] x 100
= (36 / 21) x 100
= 171.42857142857

Where: y = 3 and x = 39, so |y| = 3 and |x| = 39

### 2) What is the absolute difference between 3 and 39?

This problem is not about percent difference, but about absolute difference:

The absolute difference of two real numbers x, y is given by |x âˆ’ y|, the absolute value of their difference. The minus sign denotes subtraction and |z| means absolute value. Absolute difference describes the distance between the points corresponding to x and y on the real line.

Now that you know what is absolute difference, The solution is very simple:

absolute difference = |Y - X|
= |39 - 3| = |39 - 3| = 36
