In today’s digital world, we are constantly surrounded by stimuli that subtly influence our desires and shape our spending habits. Amid the endless stream of advertisements, social media trends, and product launches, it often becomes difficult to distinguish between our needs and our wants. As a result, many of us end up spending on the latest gadgets or lifestyle purchases simply to keep pace with others. The easy availability of credit has only made such decisions more convenient and frequent.
Unfortunately, in the process of meeting our immediate desires, we often postpone one of the most important financial priorities: investing for our future.
One effective way to overcome this behavioural challenge is through a Systematic Investment Plan (SIP). A SIP automates the investment process by transferring a fixed amount from your bank account into a mutual fund on a date of your choice every month. Since the investment happens automatically, you remove the need to consciously make an investment decision each month, helping you stay disciplined and consistent.
Over time, these small, regular investments can accumulate into a substantial corpus, powered by the twin benefits of disciplined investing and compounding. The beauty of SIPs lies in their simplicity: you can build long-term wealth gradually, often without feeling a significant impact on your monthly cash flows.
Power of compounding through SIPs
| Years | Total Invested | Corpus Growth @ 8% CAGR |
| 10 | 12.0 Lakh | 18.3 Lakh |
| 15 | 18.0 Lakh | 34.6 Lakh |
| 20 | 24.0 Lakh | 59.0 Lakh |
| 25 | 30.0 Lakh | 95.1 Lakh |
| 30 | 36.0 Lakh | 1.49 Crore |
The Real Power of Time
Notice how the growth accelerates:
- First 10 years: Rs 10k SIP grows to Rs 18 lakh
- Next 10 years (20-year total): Corpus jumps to Rs 59 lakh
- Next 10 years (30-year total): Corpus reaches Rs1.49 crore
You invest only 3 times more money over 30 years than 10 years (Rs 36 lakh vs Rs 12 lakh), but the corpus becomes 8 times larger (Rs 1.49 crore vs Rs 18 lakh). That’s compounding at work.
Assuming an 8% annualized return for illustration purposes only, a Rs 10,000 monthly SIP over 30 years may accumulate to approximately Rs 1.5 crore. Actual returns may vary. Under the above illustration, a significant portion of the corpus is attributable to the effect of compounding.
How rupee cost averaging makes SIPs effective
The structure of SIP helps you accumulate more units in equity oriented funds when equity markets fall. Suppose you have a ongoing SIP of Rs 10,000 per month.
| Month | Amount | NAV | Units |
| Jan | 10,000 | 10 | 1000 |
| Feb | 10,000 | 10.1 | 990 |
| March | 10,000 | 9.8 | 1020 |
| April | 10,000 | 9.7 | 1031 |
| May | 10,000 | 9.5 | 1053 |
| 50,000 | 9.82 | 5094 |
Notice something interesting:
- NAV started at Rs 10
- NAV fell to Rs 9.5
- Your average purchase cost became only Rs 9.82
This happened because you bought more units when NAV was lower. You have acquired 5094 units.
- Assume the NAV at the end of May is Rs 9.5.
- Portfolio Value: 5,094 × 9.5 = Rs 48,393. Loss of 1,607, which is -3.21%.
- Even though the latest NAV is down 5% from Rs 10 to Rs 9.5, your portfolio loss is only about 3.2%, because SIP averaged down your purchase cost.
- If NAV recovers to 10.5, you earn 6.97% absolute return. (5094*10.5 = 53,487, 3,487/50,000).
During the accumulation phase, lower NAVs may enable SIP investors to accumulate more units. However, market declines can continue for extended periods and returns are not assured.
- Lower NAV = more units purchased.
- Average acquisition cost comes down.
- When NAV eventually rises, gains can be higher because you own more units.
Flexibility of SIPs for different types of investors
Life comes with a lot of uncertainty and SIP offers SIPs come with a lot of flexibility to suit your goals.
You can modify it in many ways:
- Change the amount
- Change the SIP deduction date
- Pause SIP for few months
- Restart SIP
- Redeem any time, unless it is ELSS (3 year lock in)
- Top-Up SIP: Increase SIP amount every year automatically
- Start multiple SIPs for different goals
Achieving long term goals with SIPs
Goals that are far away may look hard to achieve, but with right planning it can be achievable. For instance, if you wish to save Rs 2 crore for your retirement kitty, which is 20 years away, assuming you are 40 year old, you have to start investing Rs a little over 20,000 per month, assuming a hypothetical annualized return of 12% for illustration purposes only. Actual returns may be higher or lower. You can use a SIP calculator to estimate the investment required to work towards your financial goals.
The math gets interesting if you start a bit early. Suppose if you start saving for this goal from the age of 30, you just have to put in a month SIP of close to Rs 6,000. This shows how time plays a crucial role in your wealth creation journey. Starting early with small amounts snowballs in compounding wealth without any extra burden on your cash flows.
Conclusion
To sum up, SIP offers a host of benefits which include convenience, flexibility, rupee cost averaging and compounding in the long run. You can plan for any goal – short, medium to long term using SIPs in line with your risk appetite. While SIPs help in disciplined investing and may reduce the impact of market volatility through phased investments, they do not eliminate market risk or guarantee positive returns.
Past performance may or may not be sustained in future and is not a guarantee of any future returns. Please note that these calculators are for illustrations only and do not represent actual returns. Mutual Funds do not have a fixed rate of return and it is not possible to predict the rate of return. Mutual Fund investments are subject to market risks, read all scheme related documents carefully. SIP does not assure a profit or protect against loss in declining markets.
