Translation: Compound Annual Growth Rate (CAGR) = Compound annual growth rate.

Simplified Definition: It is a mathematical measure that shows the annual growth rate of an investment or specific revenue over a defined time period (more than one year), assuming that profits are reinvested each year and that growth proceeds at a steady pace. It simply tells you: "What would the average annual growth rate be if the investment had grown at a constant and smooth rate?"

What Does It Mean for You?

  • It is the best tool for comparing historical returns between different investment options (such as comparing the growth of a particular stock with real estate sector growth over 5 years).
  • It gives you a clear and simplified picture of growth, because it ignores violent annual fluctuations and focuses on the "final result" from the starting point to the end point.
  • It is widely used when reading company reports to understand the growth rate of their sales or earnings over past years.

Common Question: Does "Compound Annual Growth Rate" reflect the true and complete picture of investment performance? Answer: No, and this is its main weakness. Because it "smooths" the numbers and converts them to a straight line, it hides the amount of "risk and volatility". Your investment may have fallen 50% in the first year and then risen dramatically in the second year; the CAGR metric will show you a pleasant positive average, hiding the fact that the investment was highly risky and volatile.
