Calculate Growth Now →The Basic Growth Percentage Formula
The most common method for calculating growth percentage involves comparing an initial value to a final value. Here's the formula:
Growth Percentage = [(Final Value - Initial Value) / Initial Value] * 100
Let's break down this formula with an example:
- Identify the Initial and Final Values: Suppose your company's revenue was $100,000 at the start of the year (Initial Value) and grew to $120,000 by year-end (Final Value).
- Apply the Formula: Insert these values into the formula: [($120,000 - $100,000) / $100,000] * 100.
- Calculate: This simplifies to ($20,000 / $100,000) * 100 = 0.20 * 100 = 20%.
Therefore, the growth percentage for your company's revenue is 20%.
Growth Percentage Over Time
Often, you'll want to determine the average growth percentage over multiple periods. Here's how to calculate it:
- Collect Data: Gather data for each period you want to analyze (e.g., monthly sales figures for a year).
- Use the Compound Annual Growth Rate (CAGR) Formula: While not strictly a "percentage," CAGR provides an annualized growth rate:
CAGR = [(Ending Value / Beginning Value)^(1 / Number of Years)] - 1
For example, if a business's revenue grew from $50,000 to $75,000 over 5 years, the CAGR is: [($75,000 / $50,000)^(1/5)] - 1 = (1.5)^(0.2) - 1 = 1.0845 - 1 = 0.0845, or 8.45%.
Real-World Applications of Growth Percentage

Tips for Accurate Growth Percentage Calculations
