Understanding how to find percentage difference is important for making accurate comparisons. The percentage difference formula measures the relative difference between two values compared to their average:
Percentage Difference = (|Value 1 - Value 2| ÷ ((Value 1 + Value 2) ÷ 2)) × 100
Value 1 = 80
Value 2 = 100
Percentage Difference = (|80 - 100| ÷ ((80 + 100) ÷ 2)) × 100
= (20 ÷ 90) × 100
= 0.222... × 100
= 22.22%
The percentage difference is 22.22%, indicating how far apart the two values are relative to their average.
Our percentage change calculator uses these fundamental relationships:
Using this percent increase calculator, you can easily solve for any unknown value when you have any two other values.
