YoY Growth Formula


YoY Growth = (Current Year Value / Previous Year Value) - 1


  • Current Year Value = the most recently reported annual financial metric value

  • Previous Year Value = the previously reported annual financial metric value

Year-over-Year Growth Calculation Example

As an example, a company has $30 million in earnings, according to their most recent annual financial report, whereas, the previous year, the company reported $25 million in earnings.

Given the following:

  • Current Year Value = $30 million

  • Previous Year Value = $25 million

We then plug the values into the formula to get the YoY growth rate:

  • YoY Growth = (Current Year Value / Previous Year Value) - 1

  • YoY Growth = ($30 million / $25 million) - 1 = 0.2 or 20.0%

The result of a 20% year-over-year growth rate indicates that the company grew their earnings by 20% in one year.
