What is compound interest?

The profit earned from investments, deposits, etc., added to the initial principal amount is called "compound interest." Let's take deposits as an example. A deposit earns interest, but the amount of interest included in the deposit is the principal amount, and the next time the interest is calculated, the interest grows.

There is a significant difference between simple interest and compound interest over the long term, and the higher the interest rate, the greater the difference in long-term investment with compound interest. Asset management can take advantage of the effects of compound interest to increase assets favorably. Therefore, it is very important to understand how it works.
