Percentage Change & Difference Calculator

Calculate percentage increase, decrease, percentage difference, and percentage modifier additions

Percentage Increase Result
+25.00%
Step-by-Step Mathematical Calculation:
  • Original Value V1 = 80
  • New Value V2 = 100
  • Absolute Change = V2 - V1 = 100 - 80 = 20
  • Percentage Change = (Change / |V1|) × 100 = (20 / 80) × 100 = 25.0000%

Mathematical Formulas & Calculation Methods

Percentage Change Formula (V1 to V2)

Measures relative shift from initial value V1 to final value V2.

Percentage Change = [ (V2 - V1) / |V1| ] × 100

Percentage Difference Formula

Compares two numbers V1 and V2 relative to their average.

Percentage Difference = [ |V1 - V2| / ((V1 + V2) / 2) ] × 100

Worked Step-by-Step Examples

Example 1: Percentage Increase from 80 to 100

"Find percentage change when a value increases from 80 to 100."

Steps:

  • Change = V2 - V1 = 100 - 80 = 20.
  • Percentage Change = (20 / 80) × 100 = 0.25 × 100 = +25.0%.
Result: +25.0% Increase
