**1. What is compound interest?**

Compound interest is a powerful concept that can help you grow your wealth over time. It works by adding interest to your principal, and then calculating interest on the new total. This means that your money has the potential to grow at an exponential rate, rather than a linear one.

Essentially Compound Interest is your money growing on itself!

**2. Examples of Compounding in action**

Below we'll explore the power of compound interest by looking at examples of how a one-time $10,000 investment can grow over 10, 20, 30, and 40-year time periods, with an interest rate of 8% which is a conservative rate of return for an S & P Index Fund. We'll also add one example of investing $10,000 per year for 30 years at 8% interest.

__Example 1: Investing $10,000 for 10 years at 8% interest__: If you invest $10,000 for 10 years at an interest rate of 8%, your investment will grow to $25,937.38. This means you will have earned $15,937.38 in interest over the 10-year period.

__Example 2: Investing $10,000 for 20 years at 8% interest: __If you invest $10,000 for 20 years at an interest rate of 8%, your investment will grow to $48,843.57. This means you will have earned $38,843.57 in interest over the 20-year period.

__Example 3: Investing $10,000 for 30 years at 8% interest__: If you invest $10,000 for 30 years at an interest rate of 8%, your investment will grow to $104,389.74. This means you will have earned $94,389.74 in interest over the 30-year period.

__Example 4: Investing $10,000 for 40 years at 8% interest:__ If you invest $10,000 for 40 years at an interest rate of 8%, your investment will grow to $221,907.12. This means you will have earned $211,907.12 in interest over the 40-year period.

Now, what happens if instead of investing a lump sum of $10,000 one time, you are investing $10,000 every year:

__Example 5: Investing $10,000 per year for 30 years at 8% interest:__ If you invest $10,000 per year for 30 years at an interest rate of 8%, your total investment will be $300,000, and it will grow to $731,938.27. This means you will have earned $431,938.27 in interest over the 30-year period.

As these examples show, the longer you invest your money, the more it has the potential to grow through compound interest. Additionally, by adding regular contributions to your investment, compound interest can grow your money even more. Keep in mind that these are examples, and the actual interest rate will depend on the financial institution and the investment conditions.
