What is the Growth Percentage Formula?

The growth percentage formula helps you quantify the change in a value over a specific period. It's expressed as a percentage, making it easy to understand and compare growth across different datasets. The basic formula is:

Growth Percentage = [(Current Value - Previous Value) / Previous Value] * 100

This formula calculates the difference between the current and previous values, divides it by the previous value (the starting point), and then multiplies by 100 to express the result as a percentage.

How to Calculate Growth Percentage: A Step-by-Step Guide

  1. Identify the Current and Previous Values: Determine the values you want to compare. For example, this could be this month's revenue and last month's revenue, or this year's customer base compared to last year's.
  2. Calculate the Difference: Subtract the previous value from the current value.
  3. Divide by the Previous Value: Divide the difference you calculated in step 2 by the previous value. This result shows the growth relative to the starting point.
  4. Multiply by 100: Multiply the result from step 3 by 100 to convert it into a percentage.

For example, if your website had 500 visitors last month and 650 visitors this month, the growth percentage is calculated as follows:

[(650 - 500) / 500] * 100 = 30%

This means your website traffic grew by 30% from last month to this month.

Different Types of Growth Rates

Growth rates can be applied to various metrics across different contexts. Here are a few common types:

  • Revenue Growth Rate: Measures the percentage change in revenue over a period.
  • User Growth Rate: Tracks the percentage change in the number of users or customers.
  • Sales Growth Rate: Indicates the percentage change in sales volume or value.
  • Compound Annual Growth Rate (CAGR): Calculates the average annual growth rate of an investment over a specified period, assuming profits are reinvested during the term.

Beyond the Formula: Interpreting Growth Percentage

While the growth percentage formula provides a number, it's important to understand what that number means in the context of your specific situation. Consider the following factors:

  • Industry Benchmarks: Compare your growth percentage to industry averages to see how you stack up against competitors.
  • Market Conditions: Economic factors and seasonal trends can influence growth rates.
  • Business Goals: Align your growth targets with your overall business objectives. What is a sustainable growth rate for your organization?
