When it comes to building wealth, few financial principles are as powerful as compound interest. Regardless if you are investing for retirement; saving for your child’s education; or growing your money, the ability to understand compound interest will dramatically change your financial future. Compound interest is critical to understanding smart financial literacy because it allows your money to grow exponentially over time, especially when done with the correct interest rates and strategies.
In this blog, we are going to take a closer look at what compound interest is, how it works, and most importantly, why it works for you. Along with that, we will give you the necessary tool to use its power to maximize long-term savings and make educated financial investing decisions.

Meaning, compound interest is more than just your initial deposit growing. Compared to simple interest which is calculated only on your initial deposit, compound interest allows for your money to grow at a growing rate.
Suppose you planted a tree. With compound interest, your tree grows the same number of fruit each year. But with compound interest, the fruit will produce new trees—and the new trees will grow more fruit. Your orchard grows over time, all due to compounding.
