How to calculate percentage change
Percentage change measures the difference between two values as a percentage of the original. The formula is: ((New − Original) / Original) × 100.
A positive result is a percentage increase, a negative result is a percentage decrease. For example, going from 100 to 125 is a 25% increase.
