Percentage Change Rechner — Formel

How to Calculate Percentage Change

Formula

% Change = [(New - Old) / Old] * 100

Percentage change measures the relative difference between two values. A positive result indicates an increase; negative indicates a decrease. Using the absolute value of the old value in the denominator handles cases where the old value is negative.

Lösungsbeispiel

A price changes from $80 to $100.

  1. Change = 100 - 80 = 20
  2. % Change = (20 / 80) * 100 = 25%
  3. Ratio = 100 / 80 = 1.25
  4. The price increased by 25%
