How To Calculate Percent Difference?

Percent difference = (frac{|A – B|}{frac{A + B}{2}} times 100%)

Percent difference = (frac{2|A – B|}{A + B} times 100%)

Let (A) = first value and (B) = second value

Compute absolute difference: (|A – B|)

Compute average: (frac{A + B}{2})

Divide: (frac{|A – B|}{frac{A + B}{2}})

Multiply by 100 to get percent difference
