Whether you’re investing in stocks, mutual funds, fixed deposits, or savings accounts, compound interest can significantly increase your returns. In this guide, you’ll learn how compound interest works, how to calculate it, and why it is often called the “eighth wonder of the world.”<\/p>\n

What Is Compound Interest?<\/h2>\n
Compound interest is the interest earned on both your original investment (principal) and the interest accumulated over previous periods.<\/p>\n
Unlike simple interest, which is calculated only on the principal amount, compound interest allows your money to grow faster because interest earns additional interest over time.<\/p>\n
