If you go by what several online finance experts claim, Albert Einstein supposedly said, \u2018Compound interest is the eighth wonder of the world. He who understands it earns it; he who doesn\u2019t pays it.\u2019 Now whether or not Einstein actually said it, this statement is quite true. <\/p>\n\n\n\n

Understanding the basics of compound interest and its importance when it comes to your investment journey is just as crucial as knowing the secret ingredient that makes a recipe stand out. So let\u2019s dive in.<\/p>\n\n\n\n

What is compound interest? <\/strong><\/h2>\n\n\n\n

You can think of compound interest as \u2018interest on interest\u2019, or your money making more money for you. That\u2019s because compound interest is what you get when your initial interest gets added to your principal, so that subsequently, you get to earn interest not just on your initial principal amount but also on the interest that that principal amount has earned. <\/p>\n\n\n\n

For instance, say you parked \u20b920,000 in a savings account with a 5% interest rate per annum, compounded annually. At the end of the first year, you would earn \u20b91,000 on your principal. Now, in the second year, due to compound interest, you would earn 5% not on the initial \u20b920,000 but on your new balance of \u20b921,000. In fact, if you were to leave \u20b920,000 in such a savings account for 30 years without ever adding another rupee to it, you would still end up with around \u20b986,000. <\/p>\n\n\n\n

Money growing at an accelerated rate <\/strong><\/h2>\n\n\n\n

With compound interest, your money keeps growing at an exponentially increasing rate. Compound interest works as a catalyst, increasing the earning potential of your invested amount. To really understand its power, let\u2019s compare it with simple interest. <\/p>\n\n\n\n

With simple interest, only your initially invested amount earns interest, not the returns earned on it. So, carrying on with the above example, if \u20b920,000 earned simple interest of 5%, at the end of 30 years, you would end up with \u20b950,000. The difference of about \u20b936,000 is the result of the magic of compounding. <\/p>\n\n\n\n

The formula for compound interest <\/strong><\/h2>\n\n\n\n

Let\u2019s take a look at the mathematical formula for compound interest. <\/p>\n\n\n\n

Compound interest = P(1 + r\/n)nt<\/sup> <\/p>\n\n\n\n

Here, P is the principal amount or the initially invested amount. The annual rate of interest is r,  n is the compounding frequency, and t is the number of years the principal is invested for. <\/p>\n\n\n\n

You can use online compound interest calculators to understand how large of a corpus you can build by investing in different securities with different rates of returns. Such calculators are free to use, give accurate estimations, and only take a few seconds. There is no need for tedious manual calculations.<\/p>\n\n\n\n

Compound interest frequency <\/strong><\/h2>\n\n\n\n

The compound interest frequency can differ for different investment and loan products. It can be daily, monthly, quarterly, semi-annual, or annual. The frequency or the compound interest periods do matter because the more frequently interest is compounded, the more your money can grow over time. <\/p>\n\n\n\n

Thus, essentially, the higher the compound interest frequency, the greater the interest you\u2019ll earn. <\/p>\n\n\n\n

The earlier you begin, the better it is <\/strong><\/h2>\n\n\n\n

You might\u2019ve noticed that the compound interest formula has a time component. The longer you keep your money invested, the greater the power of compounding. <\/p>\n\n\n\n

Let\u2019s say you begin a systematic investment plan at age 27 and invest \u20b95,000 a month in a fund with an estimated 8% return per annum.  By the time you turn 62, your corpus will have grown to about \u20b91 crore. Over those 35 years, the total amount you will have invested will be only around \u20b921 lakh, while the rest will be the returns. <\/p>\n\n\n\n

But if you waited 10 years and began investing in the same SIP at the age of 37, by the time you turned 62, you would end up with a corpus of only about \u20b946 lakh. This means a delay of 10 years in starting your investment can reduce its value by more than half! And that\u2019s why the best time to begin saving and investing for your financial goals is right now. <\/p>\n\n\n\n
