Understanding Percentage Change

How to Calculate Percentage Change?

Percentage change measures the relative difference between an original value and a new value. It's commonly used to track growth or decline in various contexts like business, finance, and academics.

Percentage Change = ((New Value – Original Value) / Original Value) × 100

Follow these steps:

  1. Subtract the original value from the new value
  2. Divide the result by the original value
  3. Multiply by 100 to convert to a percentage

Practical Example

Let's say your monthly revenue increased from $5,000 to $6,500. Here's how to calculate the percentage change:

Step 1: Subtract original value from new value: 6,500 - 5,000 = 1,500

Step 2: Divide by original value: 1,500 ÷ 5,000 = 0.3

Step 3: Multiply by 100: 0.3 × 100 = 30%

Result: You experienced a 30% increase in revenue.
