osits. You plan to invest the same for 10 years. If you choose to go for Bank A, the total amount that you will receive at maturity (10 years) will be 2,36,736 rupees. You will receive an accrued interest of more than the principal itself—1,36,736 rupees.
The same amount, if invested in Bank B, would fetch a final amount of 1,79,085. It means an accrued interest of 79,085 rupees. Now, as you can see, everything being constant, the same amount of principal when invested at two different rates of interest gives you a significant difference in the amount (57,652 rupees) received at the end of maturity. What seemed like a small differential of 3% resulted in a difference of a huge difference of 57,652 rupees, almost 58% more returns of your principal amount. So that’s the power rate of interest holds in compounding.
Period of Investment
Another very important factor in compounding is the period for which you will be investing. In the example above, if the same amount invested in Bank A would have been deposited for 15 years instead of 10, the amount you would have received at maturity is 3,64,248 rupees. The compounding works even quicker after a certain period. The difference in the interest accrued between 5 years (57,652 rupees), 10 years (1,36,736 rupees), and 15 years (2,64,248 rupees) would give you an idea. Hence, the longer your period of investment, the more you would gain from the transaction.
How can Compound Interest Help You?
- If you have a limited or fixed source of income- Compound interest helps a great deal in increasing wealth for people who have a limited or fixed source of income. If you get a fixed salary each month, it is advisable to cut down on your expenses and invest your savings in a recurring deposit bank account. Not only will your principal amount be saved, but your money will increase over time as well. Investing your money at compound interest is the best way to increase your wealth. You can deposit a fixed sum of money each month as a recurring deposit in the bank. The interest keeps on accumulating over the years.
- Increased income in less time- In comparison to simple interest, compound interest is beneficial if you want to gain more income in less time. Since you get an additional interest on both the principal and the amount of interest, your income increases rapidly. Therefore, if you want to gain more in a short amount of time, you should go for a compounded rate of interest rather than simple interest.
- Money keeps growing if you invest it for long periods- If you invest your money at a simple interest rate, it takes years to get it doubled. However, if you invest it at a compounded rate of interest, the money gets doubled sooner. The majority of the people invest their money as fixed deposits in banks for 5 years, 10 years, or even more than that. The interest on your principal for all these years gets accumulated and turns into a huge sum of money. The additional interest on the interest also keeps on growing for years. At the time of maturity, you get almost double the amount of money than your principal amount.
You can invest for a short period too, such as for 2 or 3 years, but it will give you less interest, and your money will not increase with as much speed as it does during a long period of investment. The longer your period of investment is, the more your wealth will increase.
If you want lump-sum money- If you have one bank account, it gets difficult to manage your savings and expenses. To buy an expensive thing such as gold or a car, a lot of people pay the money in installments. Some money as a downpayment is still required. But, how can you make savings if you keep on spending the money? Therefore, it is advisable to invest a fixed amount of money, such as 5,000 rupees, as a recurring deposit in a bank account for some years. At the time of maturity, you will get lump-sum money that you can use to make a down payment or make another investment. People also deposit a large amount of money in banks as fixed deposits. You again compound interest for years on the fixed dep
