Find the absolute difference between the two values: |A – B|
Find the average of the two values: (A + B) / 2
Divide the absolute difference by the average: |A – B| / ((A + B) / 2)
Multiply the result by 100 to get the percentage difference: [|A – B| / ((A + B) / 2)] × 100
Use the formula: Percentage Difference = |A – B| / ((A + B) / 2) × 100
