What is Compound Growth?

May 11, 2023

Compound growth is a fundamental concept in investing that has the power to significantly impact the growth of investments over time. It's a simple but powerful idea that may help investors pursue their financial goals and build long-term wealth. Interestingly, this is also a large part of many investment strategies that focus on multi-generational wealth. 

At its most basic level, compound growth refers to earning interest not just on your original investment, but also on the interest that your investment earns over time. This means that as your investment grows, the amount of interest it earns also grows, leading to a compounding effect that may accelerate the growth of your investment. How fun is that!


Quick disclaimer: these figures are mathematical, but do not demonstrate exactly what will happen with your needs as an investor. Always speak to a financial professional before making decisions. This post is made to inform, not instruct. While the mathematical concept of compound interest occurs, this post in no way suggests it will occur with every investment or investor.

Ok, let's say someone invests $10,000 in a mutual fund that earns an annual return of 5%. After one year, your investment would be worth $10,500. But if you leave that money in the mutual fund and earn another 5% the next year, your investment would be worth $11,025. Over time, the growth would compound, and your investment could grow significantly larger. 

The power of compound growth is particularly pronounced over longer time horizons. Even a small difference in annual returns usually has a big impact over time. For example, if you invested $10,000 in a mutual fund that earned 5% per year over 30 years, your investment would be worth $43,219. But if you earned a slightly higher return of 6%, your investment would be worth $57,435. That's a difference of over $14,000, just from a 1% difference in annual returns.

Compound growth is important for investors because it allows them to achieve their financial goals more quickly and efficiently. By earning interest on their interest, investors may grow their wealth faster and more consistently over time. This may help them achieve important financial milestones, such as buying a home, funding their children's education, or saving for retirement.

The power of compound growth is particularly pronounced when investing in the stock market. Over the long term, stocks have historically outperformed other asset classes, such as bonds and cash. By investing in a diversified portfolio of stocks, investors may take advantage of the power of compound growth to build long-term wealth.

It's important to note that compound growth works both ways. While it may help investors grow their wealth, it may also work against them if they have debt with a high interest rate. The interest on their debt may compound over time, making it harder and harder to pay off. That's why it's important to not only focus on growing your investments, but also managing your debt effectively.


As an investor, it's important to understand the power of compound growth and how it can impact your financial future. Here are some key points to keep in mind:

  1. Start investing early - The earlier you start investing, the more time you have for compound growth to work its magic.
  2. Stay invested for the long term - The longer you stay invested, the more time your investments have to potentially grow through compound growth.
  3. Focus on consistent, long-term growth - Consistent, long-term growth can have a bigger impact than short-term gains or losses.
  4. Avoid high fees and taxes - High fees and taxes can eat into your investment returns and reduce the power of compound growth.


By keeping these key points in mind, you may harness the power of compound growth to build long-term wealth and pursue your financial goals.
