What is the percentage difference between V1 and V2?
What is the percentage change (increase / decrease) from V1 to V2 ?
Now, if we want to talk about % difference, we will need a difference or two numbers that aren't the same. Take the numbers 15 and 25 as an example; the difference between them is 10. So now we must convert 10 to a percentage.
We will need to represent the absolute difference as a percentage by dividing it by the average of those two integers. The following is the computation method:
- Determine the absolute difference between two numbers: 15 25 = -10
- Take the average of those two figures: (15 + 25)/ 2 = 20
- Calculate the difference by dividing it by the average: 10/20 = 0.5
- Transform this decimal number form into percentages. 0.5 x 100= 50 which is 50 %.
That is how you calculate the percentage difference. Therefore, the percentage difference formula can be derived from these equations.
The formula we employ to arrive at this value is as follows:
Percent difference formula
Excel/ Spreadsheet Formula
=(abs(cell1-cell2)/((cell1+cell2)/2))*100
Steps:
- Replace cell1 with the initial value or Value 1
- And cell2 with the final value or Value 2
Example:
Let's look at a few scenarios when discussing percentage differences is important. Assume you wish to compare the size of two businesses in terms of employees.
