Understanding CAGR in Investing
Compound Annual Growth Rate (CAGR) is one of the most accurate ways to calculate and determine returns for anything that can rise or fall in value over time.
Unlike absolute returns, CAGR accounts for the time factor, making it the gold standard for comparing the performance of stocks, mutual funds, and real estate.
