Have you ever wondered how a small investment of ₹1,000 can help build a fund worth lakhs over time? One important reason behind this is the Power of Compounding.
Compounding simply means that the returns earned on your investment are reinvested, allowing you to earn returns on those accumulated returns as well. This is why time plays an important role in long-term investing.
What Is the Power of Compounding?
When you keep the interest or earnings from your initial investment invested, you can earn returns on both your original investment and the accumulated earnings.
This process is known as compound growth.
Simple example:
- You invest ₹10,000.
- You earn a 10% return in the first year, increasing your investment value to ₹11,000.
- In the second year, the 10% return is calculated on ₹11,000, not just the original ₹10,000.
- As a result, the amount on which returns are earned keeps increasing over time.
Simple Interest vs Compound Interest
The main difference between simple interest and compound interest is the amount on which interest is calculated.
| Simple Interest | Compound Interest |
|---|---|
| Interest is calculated only on the original principal amount. | Growth is calculated on the principal and accumulated interest. |
| Interest is not reinvested. | Earnings remain invested and can generate further returns. |
| Growth remains comparatively steady. | Growth can accelerate over time. |
According to SEBI’s example, an investment of ₹1 lakh earning an assumed annual return of 10% for 20 years would grow to ₹3 lakh with simple interest. With annual compounding, it could grow to approximately ₹6.72 lakh.
How Much Can a ₹1,000 Monthly SIP Grow Into?
Let’s understand the benefit of compounding through a monthly investment example.
Suppose you invest ₹1,000 every month and assume an average annual return of 8%.
| Details | Amount |
|---|---|
| Monthly investment | ₹1,000 |
| Investment duration | 25 years |
| Total investment | ₹3,00,000 |
| Assumed annual return | 8% |
| Estimated final value | Around ₹9.5 lakh |
AMFI also explains an example of a ₹1,000 monthly investment at an assumed annual return of 8%, which can grow to approximately ₹9.57 lakh over 25 years. The actual result may vary slightly depending on the calculation method and investment timing.
Note: This is only an illustrative calculation. Mutual fund SIP returns are market-linked and are not guaranteed.
How Does Compounding Work in SIP, FD, RD and PPF?
Different investment options in India can offer the benefit of compounding, but they do not all work in the same way.
- Mutual Fund SIP: You purchase mutual fund units at regular intervals. The fund’s value changes according to market performance and its NAV. Returns are not guaranteed.
- Fixed Deposit (FD): Depending on the bank’s terms, interest may be calculated and compounded monthly, quarterly or at another specified interval.
- Recurring Deposit (RD): You deposit a fixed amount every month. For example, a Post Office RD uses quarterly compounding, subject to the applicable scheme rules.
- Public Provident Fund (PPF): PPF interest is compounded annually. The government revises its interest rate from time to time.
What Are the Benefits of Starting Investments Early?
The investment duration is very important in compounding. The longer you allow your investment to grow, the greater the potential benefit of compounding.
Some benefits of starting early include:
- You can start investing with a small amount.
- You get a longer investment period.
- Your earnings get more time to generate further returns.
- It can help you build a fund for long-term goals such as retirement.
SEBI’s investor education material also highlights early investing as an important factor in benefiting from compounding.
How Does Inflation Affect Your Compounding Growth?
Suppose your investment earns an annual return of 8%, but inflation is 6%. The purchasing power of your investment will not increase at the full 8% rate because the prices of goods and services also rise over time.
Therefore, while planning your investments, it is important to understand not only the expected return but also the real return after accounting for inflation.
How Can You Benefit from the Power of Compounding?
If you are a beginner, you can follow these simple habits:
- Start early: Do not wait for the perfect time to begin investing.
- Invest regularly: Decide on a monthly investment amount based on your income and budget.
- Think long term: Choose an investment duration according to your financial goals.
- Reinvest your returns: Instead of withdrawing your earnings, let them remain invested.
- Understand the risks: Learn about the risks and potential returns before choosing an investment option.
Conclusion
You do not always need to make a large investment to benefit from the power of compounding. Regular investing, patience and a longer investment period can play an important role in your wealth creation journey.
However, remember that compounding does not guarantee returns. Actual growth depends on your investment option, returns, risk and investment duration.
