I've long noticed that many investors don't understand what CAGR is and how it affects the valuation of their portfolio. Honestly, it's one of the most underrated tools for investment analysis.

CAGR is not just some mathematical indicator — it's a way to truly see how your money works. The compound annual growth rate shows how quickly your investment would grow if it increased evenly each year. The key point: it accounts for reinvested profits, meaning the effect of compound interest. This seriously changes the picture.

Why do I consider this important? Because when you look at an investment that has fluctuated up and down over several years, CAGR gives you a single clear number that shows the real result. No need to guess whether you invested well or not.

The formula is simple: (final value divided by initial value) raised to the power of (one divided by the number of years), minus one. It sounds complicated, but in practice, it works like this: take the investment value at the end of the period, divide by the value at the beginning, raise to the power (where the exponent is one divided by the number of years), then subtract one and multiply by 100 for a percentage.

I often use this to compare different assets. For example, crypto assets over several years show wild fluctuations, but when you calculate CAGR, it gives you an honest picture of how well or poorly you earned on average per year. It helps filter out the noise of short-term volatility.

An important point: CAGR is not the actual return in each specific year. It’s a representative figure that shows the average. But that’s exactly why it’s so useful for long-term planning. If you're thinking about where to invest money for several years, CAGR is what you should primarily consider.

Now, when I look at my portfolio on Gate, I always check the CAGR for different periods. It helps understand which assets are truly working for my money and which just create the illusion of growth. If you take investing seriously, get to know this indicator — it will change your approach to evaluating investments.
