Average growth rate is a financial term used to describe a method of projecting the rate of return on a given investment over a period of time. By factoring the present and future value of a particular investment in relationship to the periods per year, you can calculate an annualized yield rate, which can be useful in the development of an investment strategy. An average growth rate calculator can be created in a Microsoft Excel spreadsheet that can accurately determine the annualized rate of return of any given investment. This article provides step-by-step instructions on how to use Excel to accurately calculate the average growth rate of an investment.
