I just learned something pretty interesting about investing—that is, how to practically evaluate how much my investment has grown over time.

Maybe you’ve also been confused when comparing different investments. This one increased by 50% in 2 years, that one by 30% in 1 year—so which one is better? That’s where CAGR (Annual Compound Growth Rate) comes into play.

CGAR is basically a financial metric that helps you calculate the average annual growth rate of an investment. It takes compound interest into account—that is, returns generating the next returns. This makes it more accurate than simply dividing the total gains by the number of years.

If you want to calculate the CAGR formula, here’s how: Take the final value divided by the initial value, then raise it to the power of (1 divided by the number of years), then subtract 1. Multiply by 100 to get a percentage. It sounds complicated, but it’s actually quite simple once you try it.

Why is it important? Because it gives you a single number to clearly understand how an investment has performed. Instead of watching the price go up and down and then up again, you can see a steady average growth trend. This is very useful when you want to compare which investment is truly better in the long term, or to plan your financial future.

I’ve found that understanding how the CAGR formula works is the key to making smarter investment decisions. Especially when you’re considering long-term opportunities.
