How it Works

The percent difference calculator finds the percent difference between two positive numbers greater than zero. The percentage difference is usually calculated when you want to know the difference in percentage between two numbers.

Note that percentage difference is quite different from percentage change. For this calculator, the order of the numbers does not matter as we are simply dividing the difference between two numbers by the average of the two numbers.

For percentage change, the order matters. It is used to relatively calculate the difference between an old number and a new one. If you would like to check our percentage change calculator, click here.

Percentage Difference is used when both values mean the same kind of thing. For example, the population of two countries. Also, in Percentage Difference we ignore any minus sign because we cannot say which value is more important, “up” (positive) or “down” (negative). We just say the difference in numbers.

The tool makes use of the absolute value of the difference between the two values and divides the result by the average of the two values to calculate the percent difference of two values.

Here is it in a simpler form:

The good thing about this calculator is that you don’t have to watch all of that happen. Its efficiency also allows for easy use.
