DiffThe order-independent difference percentage
AFirst value
BSecond value
Step-by-Step Worked Example
1. Mapped Variables
Value A
A40
Value B
B50
2. Equation Substitution
Equation with standard inputs
% Difference =
|40 - 50|(40 + 50) ÷ 2
× 100
3. Calculation Steps
Step 1: Calculate absolute difference between values

|A - B| = |40 - 50| = 10

Step 2: Calculate average value of A and B

Average = (A + B) ÷ 2 = (40 + 50) ÷ 2 = 45

Step 3: Divide absolute difference by average and scale

Difference % = (Difference ÷ Average) × 100 = (10 ÷ 45) × 100 = 22.22%

Final Resolved Percentage Difference22.22%
