How the Calculation Works
Calculates the relative difference divided by original baseline.
Formula: Change % = [(Final - Initial) / |Initial|] × 100
Practical Worked Example
Given Inputs: 100 to 125
Calculated Output: +25.00% increase
- (125 - 100) / 100 = 0.25 = 25%.
Pro Tip: Be careful when the initial value is zero, as percentage change is undefined in that case.
