Mastering the Art of Calculating Year-on-Year Growth Percentage- A Comprehensive Guide

How to Calculate Year on Year Growth Percentage

Calculating year on year growth percentage is a fundamental skill in financial analysis, business planning, and economic forecasting. It allows you to compare the performance of a company, investment, or any other metric over two consecutive years. This article will guide you through the process of calculating year on year growth percentage, providing you with a clear understanding of the steps involved.

Understanding the Concept

Year on year growth percentage is the percentage increase or decrease in a particular metric from one year to the next. It is commonly used to analyze trends, compare performance, and make informed decisions. To calculate this percentage, you need to have the values of the metric for two consecutive years.

Step-by-Step Guide to Calculating Year on Year Growth Percentage

1. Identify the Values: Obtain the values of the metric for the two consecutive years you want to compare. For example, if you are analyzing a company’s revenue, you will need the revenue figures for both the current year and the previous year.

2. Calculate the Difference: Subtract the value of the metric in the previous year from the value in the current year. This will give you the absolute change in the metric.

3. Divide by the Previous Year’s Value: Divide the absolute change by the value of the metric in the previous year. This step is crucial as it normalizes the change by the starting point.

4. Multiply by 100: Multiply the result from step 3 by 100 to convert it into a percentage. This will give you the year on year growth percentage.

5. Round the Result: Round the percentage to an appropriate number of decimal places, depending on the level of precision required for your analysis.

Example

Let’s say you want to calculate the year on year growth percentage of a company’s revenue. The revenue for the previous year was $1,000,000, and the revenue for the current year is $1,200,000.

1. Identify the Values: Previous Year’s Revenue: $1,000,000; Current Year’s Revenue: $1,200,000.
2. Calculate the Difference: $1,200,000 – $1,000,000 = $200,000.
3. Divide by the Previous Year’s Value: $200,000 / $1,000,000 = 0.2.
4. Multiply by 100: 0.2 100 = 20%.
5. Round the Result: The year on year growth percentage is 20%.

Conclusion

Calculating year on year growth percentage is a straightforward process that can provide valuable insights into the performance and trends of a company, investment, or any other metric. By following the steps outlined in this article, you can accurately determine the percentage increase or decrease from one year to the next and make informed decisions based on the data.
