What is a Percentage difference?

Percentage difference measures how much two numbers differ, expressed as a percentage. It is calculated by dividing the absolute difference between |a-b| the two numbers by the average of the two numbers and multiplying by 100.

Percentage difference formula

The formula for calculating the percentage difference is as follows:

PD = |A – B| / ((A + B)/2) * 100

  • PD = percentage difference
  • A = first value
  • B = second value

Solved Example

Example – Suppose you have two values: First value = 80, Second value = 60
To find the percentage difference between these two values

Given,

  • A = first value = 80
  • B = second value = 60

Step 1: Values to compare are 80 and 60.
Step 2: Difference = A – B = 80 – 60 = 20
Step 3: Absolute value of the difference = |A – B| = |20| = 20
Step 4: Average of the two values = (A + B) /2 = (80 + 60) / 2 = 140 / 2 = 70
Step 5: Percentage difference = |A – B| / ((A + B)/2) = 20 / 70 = 0.2857
Step 6: Percentage difference = |A – B| / ((A + B)/2) * 100 = 0.2857 * 100 = 28.57%

So, the percentage difference between 80 and 60 is approximately 28.57%.
