What is percentage change?
Percentage change measures how much a quantity has increased or decreased relative to its original value. A positive result means an increase; a negative result means a decrease. It's used to compare prices, financial results, statistics, and any measurable quantity that changes over time.
Percentage change formula
Change % = ((New Value − Original Value) ÷ Original Value) × 100
Step-by-step examples
Example 1 – Price increase: An apartment was worth $180,000 and is now $220,000.
- Difference: 220,000 − 180,000 = $40,000
- Change: (40,000 ÷ 180,000) × 100 = +22.2%
Example 2 – Stock drop: A stock falls from $50 to $38.
- Difference: 38 − 50 = −$12
- Change: (−12 ÷ 50) × 100 = −24%
Common uses
