Compound interest has significant influence in wealth creation and it maximizes the potential of money overtime. It can be defined as the interest you earn on the money that you have saved and on the interest you have earned over a saving period. Simple interest on the other hand is interest that is only calculated on the principal amount, and the interest earned remains fixed. Compound interest operates uniquely across various segments of society, with the greatest benefits accruing to the Investors.

Investors can leverage compound interest to accumulate substantial wealth by consistently reinvesting earnings. Thus, resulting in an exponential growth in their portfolios and significant financial gains. Compound interest also helps mitigate the rising cost of living caused by inflation. As the prices rise, the returns from compounded investments can outperform inflation and therefore preserve purchasing power. Investors tend to opt for longer investment periods and can greatly benefit from compounding over longer time horizons.  

The primary advantage of compound interest is that it accelerates wealth growth. Unlike simple interest, compound interest considers the accumulated interest which results in higher returns. However, when it comes to borrowing, simple interest offers a significant advantage to borrowers. It keeps the total cost of borrowing lower compared to compound interest and the interest remains constant, resulting in a more predictable repayment schedule. With regards to investing, for long-term investments, compound interest significantly outperforms simple interest and this concept is illustrated in the graph below;

In the initial five years, the interest may appear modest, but after eight years, the true effect of compounding becomes evident. At that point, you’ll witness a significant upward shift in the compound interest curve. It is important to note that the simple interest curve increases at a constant rate and the compound interest curve at an increasing rate. Compound interest is more prominent in savings accounts, investments and financial markets. Whereas simple interest is commonly used for straightforward loans and financial transactions such as car loans and Certificates of Deposit (e.g., Government Bonds).

Understanding these concepts will enable you to make informed financial decisions. To fully benefit from compounding investments, be patient and consistent in reinvesting in order to build and sustain wealth.
