I noticed that many people confuse the different ways to measure investment performance. So, I decided to clarify a super useful concept: the CAGR.

So, what exactly is it? The CAGR, or Compound Annual Growth Rate, is essentially a tool to measure how your investment has truly performed over a given period. Unlike other methods that can be misleading, the CAGR accounts for the effect of compounding, that thing where your gains generate their own gains. It’s really the most honest way to see if your money has worked well for you.

To calculate the CAGR, you use this formula: (Final value divided by initial value) raised to the power of (1 divided by the number of years), then subtract 1. Essentially, it gives you a percentage representing the average annual growth rate of your investment. Step by step: divide the final value by the initial value, raise this result to the power of one over the number of years, subtract 1 from the result, and multiply by 100 to get a percentage.

Why is it important? Well, the CAGR isn’t a true rate of return; it’s more of a representative figure that shows how quickly your investment would have had to grow each year if the growth had been steady and you had reinvested your profits. It’s super useful for comparing different investments over the same period and seeing which one really gave you the best return. With this single number, you can evaluate the actual performance of your holdings and better plan your long-term investment strategy. It’s really the key to making better financial decisions.
