How It Works

How to Calculate Growth Rate

Formula

Growth Rate (%) = [(Final - Initial) / Initial] * 100

The growth rate measures the relative change between two values as a percentage. A positive rate indicates growth; negative indicates decline. The growth factor (Final/Initial) gives the multiplier: 1.30 means a 30% increase.

Worked Example

Revenue grew from $500 to $650.

initial = 500final_val = 650
  1. 01Absolute change = 650 - 500 = 150
  2. 02Growth rate = (150 / 500) * 100 = 30%
  3. 03Growth factor = 650 / 500 = 1.30
