The compound annual growth rate (CAGR) is a financial metric used to determine the annualized rate of return or growth of an investment, assuming that any profits or returns generated are reinvested at the end of each investment period throughout its entire lifespan. CAGR provides a smoothed and standardized way to assess the performance of an investment or asset over time, taking into account the compounding effect of returns.
CAGR is particularly valuable when evaluating investments with varying annual returns or when comparing the growth of different investments over the same time frame. It provides a single, easily digestible percentage figure that represents the average annual growth rate required for an initial investment to reach its final value, considering the reinvestment of any gains.
Investors and analysts use CAGR to better understand and compare the growth potential of various investments, as it eliminates the impact of volatility and provides a more consistent measure of performance.
