Understanding the concept of compound interest is often described as the “eighth wonder of the world.” Unlike simple interest, which is calculated only on the principal amount, compound interest is calculated on the principal plus the accumulated interest from previous periods. In short, it is your money making more money.

How It Works: The Snowball Effect
The true magic of compounding lies in time. When you reinvest your earnings, your investment base grows. In the beginning, the progress might seem slow, but as the years pass, the growth becomes exponential. This is known in the financial world as the “Snowball Effect.”
For example, consider a monthly contribution of $200 in an index fund with an average annual return of 8%.
•. After 10 years, you would have approximately $36,000.
•. After 30 years, that same $200 a month could grow to over $290,000
