Why Percentage Change Is Important

Percentage change is used to understand how a value has increased or decreased compared to its original value. It helps learners compare changes clearly, regardless of the size of the numbers involved.

Understanding the Concept

Percentage change measures the difference between an old value and a new value, expressed as a percentage of the original value. A positive result indicates an increase, while a negative result indicates a decrease.

Formula Used

Step-by-Step Example

• Original Value = 200
• New Value = 260
• Change = 260 − 200 = 60
• Percentage Change = (60 ÷ 200) × 100 = 30%
