It is used to measure the difference between two related values and is expressed as a percentage. For example, you can compare the price of a laptop this year versus the price of a laptop from last year.

How do you find percent difference?

When the difference between two values is divided by the average of the same values, a percentage difference calculation has occurred. The formula for percentage difference looks like this: Percentage difference = Absolute difference / Average x 100.

Why is my percent difference so high?

How much percent difference is acceptable?

How do I find the percentage difference between 3 numbers?

Let’s go step-by-step and determine the percentage difference between 20 and 30:

  1. Compute the absolute difference between our numbers: |20 – 30| = |-10| = 10.
  2. Compute also their average: (20 + 30) / 2 = 50 / 2 = 25.
  3. Divide the difference by the average: 10 / 25 = 0.4.
  4. Express the result as a percentage: 0.4 * 100 = 40\%

When to use percent difference?

Percent difference is calculated as the difference between two values, divided by the average of the two values, expressed in terms of percentage.
