## How to Find the Percent Difference Calculator?

The **percent difference** of any two numbers is the absolute value of the ratio of their difference and their average multiplied by 100. The percent difference is calculated using the formula:

**Percent Difference = |Difference / Average| × 100%**, | | indicates "mod value"

**Solved Example:**

Find percent difference if the given values are 100 and 200?

**Solution: **

Given: Intial value(a) = 100, final value(b) = 200

Percent Difference = |Difference / Average| × 100%

= |(a − b) / ((a + b)/2)| × 100%

= |(100 − 200) / ((100 + 200)/2)| × 100%

= |-100 / 150| × 100%

= |-0.666| × 100%

= 0.666 × 100%

= 66.666%

Therefore, the percent difference of two values = 66.666%

Similarly, you can try the calculator to find the percent difference for the following values.

a) Initial value = 80, Final value = 280

b) Initial value = 220, Final value = 120
