How to Calculate Year-on-Year Growth: English SEO Article

Year-on-year growth, commonly used in financial analysis, refers to the growth rate compared to the same period last year. Through year-on-year analysis, businesses can gain insights into the changes in their operations over different time periods, providing strong support for decision-making.

1. Method of Calculating Year-on-Year Growth

The formula for calculating year-on-year growth is: Year-on-year growth rate = (Current period value - Same period value last year) / Same period value last year × 100%. In this formula, the "current period value" refers to the numerical value for the current time period, while the "same period value last year" refers to the numerical value for the same time period in the previous year. By calculating the difference between the two and dividing it by the value from the same period last year, followed by multiplying by 100%, one can obtain the year-on-year growth rate.

2. Significance of Year-on-Year Growth

Year-on-year analysis helps businesses understand the development trends and changes in their operations over different years. By comparing numerical values for the same time period, the impact of seasonal and cyclical factors on the data can be eliminated, revealing a more accurate picture of the business's true growth. Additionally, year-on-year analysis allows for comparisons and analysis with historical data.
