Compound interest is the secret ingredient to building long-term wealth, yet many people don't fully understand how it works. It's a simple concept with profound effects: compound interest is the interest you earn on your initial investment, plus all the interest that has accumulated over time. In short, it's "interest on your interest."
Simple vs. Compound Interest: What's the Difference?
Imagine you invest $1,000 at a 10% annual interest rate.
- With simple interest, you'd earn $100 every year. After 10 years, you'd have your original $1,000 plus $1,000 in interest, for a total of $2,000.
- With compound interest, in the first year you earn $100. The next year, you earn 10% on $1,100, which is $110. The year after that, you earn 10% on $1,210, which is $121. This snowball effect continues, and after 10 years, you'd have over $2,593!
The Two Key Ingredients: Time and Consistency
The magic of compounding is fueled by two main factors:
- Time: The longer your money has to grow, the more powerful compounding becomes. The growth isn't linear; it's exponential. This is why starting to save and invest early is the single most important thing you can do for your financial future.
- Consistency: Regularly adding to your investments (like making monthly contributions) supercharges the process. Each new contribution begins its own compounding journey, adding to the overall snowball effect.

It can be hard to grasp the power of compounding just by reading about it. The best way to see the impact is with a compound interest calculator. You can input your own numbers—initial investment, monthly contributions, interest rate, and time—and watch how the growth accelerates dramatically in the later years.
