How To Calculate Percent Differences

Percentage difference is a simple mathematical concept that is used to compare two values and determine how much they differ from each other. It is calculated by taking the absolute difference between two values and dividing it by the average of the two values. The result is then multiplied by 100 to express it as a percentage.

Calculating Percent Difference

To calculate the percent difference between two values, we use the following formula:

(Absolute difference between values) / (Average of values) * 100

Absolute difference: The first step in calculating percent difference is to determine the absolute difference between the two values. This is done by subtracting the smaller value from the larger value. For example, if value A is 100 and value B is 110, the absolute difference would be 10.

Average of values: The next step is to determine the average of the two values. This is done by adding the two values together and dividing the result by 2. In the example above, the average of values A and B would be (100 + 110) / 2 = 105.

Multiply by 100: The final step is to multiply the result of the previous step by 100 to express it as a percentage. In the example above, the percent difference would be (10 / 105) * 100 = 9.52%.
