How to Calculate Percent Change
Percent change measures the relative change between an old value and a new value.
Percent Change = ((New − Old) / |Old|) × 100
Divide the difference by the absolute value of the old number, then multiply by 100.
((120 − 100) / 100) × 100 = 20%
Example
Price increased from $50 to $65. What is the percent change?
((65 − 50) / 50) × 100 = 30%
