About this helper
Percentage change uses the original value as the base, so it answers how much a value increased or decreased from the starting point. Percentage difference compares both values symmetrically by dividing the absolute change by the average magnitude of the two values.
What is the difference between percentage change and percentage difference?
Percentage change uses the original value as the base. Percentage difference treats both values equally and uses their average as the base.
Can the original value be zero?
