Why earning 'interest on interest' is called compound interest???
Why is 'Interest on Interest' Called Compound Interest? Compound interest refers to the interest earned not only on the initial principal but also on the interest that accumulates over previous periods. In simpler terms, it’s "interest on interest." This compounding effect causes the investment to grow at a faster rate compared to simple interest, which is calculated only on the original principal amount. Example: Compound Interest vs. Simple Interest Let’s take an example to illustrate this. Suppose you invest $100 at an interest rate of 10% per year for 3 years. Compound Interest : In year 1, you earn $10, making your total $110. In year 2, you earn 10% on $110, which gives you $121. In year 3, you earn 10% on $121, which totals $133.1. So, the total amount after 3 years would be $133.1, where the extra $3.1 is the "interest on interest." Simple Interest : If you use simple interest, you earn $10 each year based on the original $100 principal. After 3 year...
