How to Calculate Percent Change?

Understanding how to calculate percentage change is essential for analyzing financial growth, population statistics, and discount savings. Our Percentage Change Calculator simplifies this process using the standard formula.

The Percent Change Formula

((New Value - Original Value) ÷ |Original Value|) × 100

For example, if a price increases from $50 to $75:

  • Step 1: 75 - 50 = 25 (Difference)
  • Step 2: 25 ÷ 50 = 0.5
  • Step 3: 0.5 × 100 = 50% Increase
