Year-over-year (YOY) is a financial comparison method used to analyze data or measure performance over a 12-month period. It refers to comparing data or metrics from the same time period in consecutive years to identify trends, changes, or growth rates.
YOY analysis is particularly useful in identifying long-term trends and patterns that may occur within a specific industry or market. It helps highlight seasonality effects by comparing data for corresponding periods in different years and takeing into account the natural fluctuations in business cycles that may affect performance. This allows for a more comprehensive assessment of how a business or market has performed relative to previous years, considering both positive and negative impacts.
YOY analysis enables the calculation of growth rates or changes in percentages. By comparing data over a full year, it provides a broader perspective on the rate of change and helps evaluate the effectiveness of strategies or initiatives implemented over time
