The principle of compounding returns refers to the process where investment earnings generate their own earnings over time. This concept is fundamental in finance because it illustrates how investments can grow exponentially rather than linearly. When interest or returns are earned on both the initial investment (the principal) and the accumulated interest from prior periods, this leads to an increasing rate of growth.

For example, if you have an investment that yields a 5% return annually, in the first year, you earn 5% on your principal. In the second year, that 5% is calculated on the new total, which includes the original principal plus the interest earned in the first year. This cycle continues, leading to additional interest on the interest earned in previous years, which enhances the total returns over time.

Thus, compounding can significantly increase the wealth generated from investments, especially when left to grow over long periods. The longer the money is invested, the more pronounced the effects of compounding become, making it a powerful investing strategy.
