  • Useful for comparing the growth rates of different companies or investments over varying time periods
  • Helps investors assess a company's long-term growth potential and sustainability
    • High CAGR in sales and earnings may indicate a rapidly growing company (Amazon's revenue CAGR of 27% from 2010-2020)
