Year-over-year growth analysis can offer a comprehensive portrayal of a company’s financial development. To compare the growth of a company over the last year, we have to apply a formula. In this tutorial, we will show you how to use the growth over last year formula in Excel.

## Introduction to Year-Over-Year Growth

Year-on-Year (YoY) Growth compares the change in an annualized statistic over two similar periods, often the current and preceding years as of the fiscal year’s close date. This study is commonly used to compare the pace of revenue increase over the last year. Businesses can also use the YOY growth formula, which displays commercial success as a percentage over the last year.
