Math

Percentage Difference Calculator

Calculate the percentage difference between two non-zero positive numbers where neither is the initial reference.

Formula & Calculation Rule

How It Is Calculated

Diff (%) = (|V1 - V2| / ((V1 + V2) / 2)) × 100

Divide the absolute difference between the two numbers by their arithmetic mean, and multiply by 100.

Step-by-Step Example

Difference between 40 and 50

1Absolute diff: |40 - 50| = 10

2Average: (40 + 50) / 2 = 45

3Divide & multiply: (10 / 45) × 100 = 22.22%

Result: 22.22%
