Get into the world of compound interest and understand its transformative power. Learn the differences between simple and compound interest, their formulas, and how to leverage them in your financial journey.
You want to see your money increase when you set aside money for a long-term objective like retirement, a child’s college fund, or home ownership. To protect yourself from rising inflation and to turn a profit, you would like to see your initial investment generate attractive interest. While doing so, you are exerting very little effort and reducing your risk exposure. But few investments provide you with that luxury. The principle of compound interest, however, is at the heart of the handful that does. You can save and invest more wisely for the future if you comprehend how it operates.
Compound interest, usually considered to be man’s greatest invention, enables anyone to swiftly increase money while avoiding the consequences of inflation and rising living expenses.

So, what is the life-changing magic of compound interest? How is it determined, too?
In this article, we will discuss what compound interest is, how to leverage money to your advantage, and how compound interest can be used against you.
What Is Compound Interest?
At its core, compound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods on a deposit or loan. It is similar to the saying, interest on interest. Over time, compound interest results in exponential growth. For those who invest or save, it acts as a powerful force, making money grow at an accelerated rate compared to simple interest.
Simple Interest vs. Compound Interest
While both simple and compound interest are methods to calculate returns or expenses on capital, they work differently:
Simple Interest: This is calculated only on the principal amount, or on that portion of the principal amount which remains unpaid. For instance, if you invest ₹10,000 at a simple interest rate of 10% per annum, you’ll earn ₹1,000 every year, irrespective of the tenure.
Compound Interest: This system factors in the interest that accumulates on the principal amount over time. So, if you invest the same ₹10,000 at a compound interest rate of 10% per annum, the interest for the second year will be calculated on ₹11,000 (principal + interest of the previous year), making it ₹1,100.
| Parameter | Simple Interest | Compound Interest |
| Definition | Interest charged for the usage of borrowed funds over a set duration. | Interest that accumulates when principal payment is delayed, added with interest over a duration. |
| Formula | SI = (P × T × R) ⁄ 100 | CI = P(1 + R⁄100)^t − P |
| Return Amount | Offers relatively lower returns. | Generates significantly higher returns. |
| Principal Amount | Remains unchanged throughout the period. | Fluctuates throughout the borrowing term. |
| Growth | Showcases consistent growth. | Exhibits accelerating growth. |
| Interest Charged | Interest applied solely on the initial amount. | Interest applied on both initial sum and accumulated interest. |
Understanding Compound Interest
When you start your savings journey, it is very important compound interest.” What is compound interest? It’s the interest you accumulate on the previously earned interest. Let’s break this down with an example in the Indian context:
Assume you have ₹8,300. If this amount earns an annual interest of 5%, you will have ₹8,715 at the conclusion of year one. Come the end of the second year, your total becomes ₹9,150.75. This includes not only the ₹415 earned from the original deposit but also an additional ₹35.75 earned from the previous year’s interest. Although ₹35.75 might seem small, its impact has grown over the years. Even if you don’t add a single rupee more, in a decade, this amount will exceed ₹13,505. And in 25 years? You’d be looking at nearly ₹28,220, all thanks to the power of compound interest.

Rule of 72: The Indian Investor’s Friend The Rule of 72 is a quick way to guess when your investment will double. Just divide 72 by your interest rate. For example, with a 9% rate, your money will double in about 8 years (since 72 divided by 9 is 8). It’s a useful tool for Indians to check how fast their investment grows. |
Compound Interest Formula
The formula to calculate compound interest is:
The compound interest formula is A = P(1 + r/n)^(nt). Here, A is the final amount, P is the initial sum, r is the yearly interest rate, n tells how often interest is added yearly, and t is the time in years.
Compound Interest Formula Excel
For those who prefer using Excel to calculate compound interest, here’s a simple step:
Formula: =P*(1+r/n)^(n*t)
You can enter the principal amount, rate of interest, number of times it’s compounded, and the time in respective cells and use the formula to get the result.
Simple Interest Formula
Simple Interest is calculated as:
A = P (1 + rt)
A = the total sum after n years, factoring in interest.
P = the starting amount or the initial bill/investment.
r = the yearly interest rate (in decimal form).
t = the duration in years for which the money is kept or owed.
To truly understand the impact, let’s take a hypothetical example:
Rohit invests ₹1,00,000 at a 10% annual interest rate compounded yearly. At the end of the first year, he earns ₹10,000 in interest. In the second year, he earns interest not just on his initial investment, but also on the previous year’s interest. Thus, at the end of the second year, his interest is ₹11,000, making his total ₹1,21,000. This continues, magnifying his returns year after year.
Making Compound Interest Work for You
Start Early:
The principle behind compound interest is that the interest you earn starts earning interest, leading to exponential growth over time. By starting early, you allow more time for this compounding effect to work its magic on your investments. For instance, consider two individuals: one starts investing at 20 and another at 30. Even if the latter invest more money, the former can end up with a larger corpus simply due to the added advantage of those extra ten years of compounding. So, even if your initial investment is modest, the sheer duration can have a transformative impact on the growth of your savings.
Reinvest Dividends:
When you earn dividends or interest from your investments, you typically have two options: you can either withdraw them for immediate consumption or reinvest them back into the market. By choosing to reinvest, you essentially increase the principal amount on which future interest/dividends will be calculated. Over time, this creates a cycle where you earn interest on the interest and dividends on the dividends, supercharging the compounding effect and leading to a snowballing growth of your investments.
Regular Investments:
While it’s beneficial to start early and reinvest dividends, the consistency of investing is another crucial aspect. The Systematic Investment Plan (SIP) is a testament to this principle. Popular in India, SIPs allow investors to invest a predetermined amount regularly, be it monthly or quarterly, into their chosen mutual funds. This not only instils financial discipline but also mitigates the risk associated with market timing, leveraging the benefits of rupee cost averaging. Over a period, regular contributions can substantially increase the investment corpus, especially when combined with the compounding effect.
Research High-Compounding Opportunities:
Not all investment avenues compound interest at the same frequency. Some might offer quarterly compounding, while others might compound it monthly or even daily. The more frequently interest is compounded, the more beneficial it is for the investor. For example, monthly compounding will yield higher returns than annual compounding over the same period. Thus, it’s prudent for investors to scout for investment opportunities where the frequency of compounding is higher, ensuring they maximise their returns over time.
Tips to Make the Maximum of Compounding
Compound interest is a fantastic method for increasing your wealth, but to maximise its potential, you can follow these steps:
- Start early: It’s ideal to begin investing as soon as you start earning money. However, if you haven’t started early, now is still a good time to begin. Compounding is most effective when you start early and maintain long-term investments
- Exercise discipline: To truly harness the power of compounding and achieve your financial objectives, you must stay disciplined in your investments. This means initiating your investment journey and ensuring regular contributions. As demonstrated above, even a slight delay or interruption in investments can significantly affect your ability to leverage compounding
- Embrace patience: Similar to the adage that Rome wasn’t built in a day, your wealth-building journey won’t happen overnight. It’s crucial to recognize that it will take time to accumulate a substantial sum to meet your financial goals. Patience is the linchpin here. There may be moments when personal biases or market fluctuations tempt you to cease regular investments, but this can undermine your objectives.
Compounding Interest Periods
Compounding periods represent the intervals during which interest is added to an account. Interest can compound annually, semi-annually, quarterly, monthly, daily, continuously, or follow any other schedule.
Interest may accrue daily but only gets credited monthly. The moment interest is credited or added to the existing balance marks the point when it begins generating additional interest. Different compounding frequency schedules are commonly applied to various financial instruments:
- Savings accounts and money market accounts often employ a daily compounding schedule at banks
- Certificate of deposit (CD) accounts typically compound interest on a daily or monthly basis
- Series I bonds see interest compounded semiannually, or every six months
- Loans, including student loans, frequently involve monthly compounding, though it may be termed ‘interest capitalisation’
- Credit cards commonly apply daily compounding, which can lead to rapid interest accumulation.
Compounding Period Frequency
Increased frequency of interest compounding benefits the investor or creditor, while for a borrower, it has the opposite effect. The fundamental principle is that the greater the number of compounding periods, the larger the resulting compound interest
This showcases how the number of compounding periods can impact a ₹10,000 loan with a 10% annual interest rate over a ten-year duration.
