How to Calculate the Mean Value

If the company wants to compare this season’s growth compared to last season, it will use YoY reports.

Arguably, the biggest advantage of year-over-year comparisons is that they minimize the effect of seasonality. Both the pageviews and sales have increased YOY by 20% and 50% respectively, resulting in an overall 25% YOY increase in conversion rate.

By comparing a company’s performance to its performance in the same period of the previous year, you can see how its operations have changed over 12 months. It often fails to account for extraordinary or one-time events that distort comparisons. For example, a major acquisition or divestiture in the previous year might skew YOY figures, making it difficult to assess organic growth. External factors such as regulatory changes, natural disasters, or global disruptions—like the COVID-19 pandemic—can also affect YOY results, requiring analysts to contextualize the data.
