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| 
  × 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 540 and 230?

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

% Difference
= [(|230| - |540|) / (|540| + |230|)/2] x 100
= [(230 - 540) / (540 + 230) / 2] x 100
= [-310 / 770 / 2] x 100
= (-310 / 385) x 100
= -80.519480519481

Where: y = 540 and x = 230, so |y| = 540 and |x| = 230

2) What is the absolute difference between 540 and 230?

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

The absolute difference of two real numbers x, y is given by |x − 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|  = |230 - 540| = |230 - 540| = 310
