New Delhi: Turning an initial saving of ₹1 lakh into a ₹10 lakh investment corpus may appear challenging, but a combination of a lump-sum investment and disciplined monthly Systematic Investment Plan (SIP) contributions can potentially help investors reach the target over time.
A recent illustration by NDTV Profit shows how the journey could look under different monthly SIP amounts and an assumed annual return of 12%. The calculations demonstrate the role of regular investing and compounding, while also highlighting that mutual fund returns are market-linked and cannot be guaranteed.
The calculation assumes that an investor starts with ₹1 lakh invested upfront and continues with a fixed monthly SIP in a mutual fund. The eventual corpus depends on the amount invested every month, the investment period and the return generated by the underlying fund.
₹5,000 monthly SIP could cross ₹10 lakh in eight years
Under the first illustration, an investor starts with a lump-sum investment of ₹1 lakh and adds ₹5,000 every month through an SIP.
At an assumed annual return of 12%, the investment is projected to reach approximately ₹10.33 lakh after eight years.
The calculation breaks down as follows:
- Initial lump-sum investment: ₹1 lakh
- Monthly SIP: ₹5,000
- Investment period: 8 years
- Total amount invested: ₹5.80 lakh
- Assumed annual return: 12%
- Estimated returns: ₹4.53 lakh
- Estimated final corpus: ₹10.33 lakh
This means the investor would contribute ₹5.80 lakh over the eight-year period, while the remaining ₹4.53 lakh in the illustration would come from investment returns.
The example highlights the impact of staying invested for several years. Rather than depending entirely on the initial ₹1 lakh, the investor continues adding money every month, allowing the growing corpus to potentially benefit from compounding.
₹7,000 SIP can reach the target faster
Increasing the monthly SIP amount can shorten the time required to build the target corpus.
In another illustration, an investor begins with the same ₹1 lakh lump sum but invests ₹7,000 every month.
At an assumed annual return of 12%, the corpus could grow to approximately ₹11.22 lakh in seven years.
The calculation is:
- Initial lump-sum investment: ₹1 lakh
- Monthly SIP: ₹7,000
- Investment period: 7 years
- Total amount invested: ₹6.88 lakh
- Assumed annual return: 12%
- Estimated returns: ₹4.35 lakh
- Estimated final corpus: ₹11.22 lakh
The higher monthly contribution allows the investor to cross the ₹10 lakh milestone approximately a year earlier in this illustration. However, the investor also contributes a larger amount during the period.
Why the starting ₹1 lakh matters
Starting with ₹1 lakh gives the investment a head start because the money is invested from day one.
Instead of beginning the SIP with a zero balance, the investor already has an initial corpus that can potentially generate returns. Monthly contributions then add to that amount and create a larger base for compounding.
However, the initial investment alone is not enough to reach ₹10 lakh quickly. The examples show that disciplined monthly contributions play a major role in building the corpus.
For investors who have already accumulated ₹1 lakh, the key decision is therefore not simply where to invest the money but also how much they can consistently contribute each month without disturbing their regular financial commitments.
12% return is only an assumption
The most important caveat in these calculations is the assumed 12% annual return.
The illustration should not be interpreted as a promise that an equity mutual fund SIP will deliver 12% every year. Equity-oriented investments are market-linked, and returns can fluctuate depending on market conditions.
NDTV Profit also points out that investors may want to examine the same strategy using lower return assumptions. At an assumed annualised return of 8%, the ₹1 lakh starting investment would grow at a slower pace and the monthly SIP would need more time to reach the ₹10 lakh milestone.
This difference becomes increasingly important over longer investment periods. Even a few percentage points of difference in annual returns can materially change the final corpus when compounding works over several years.
SIP amount and investment period both matter
The two illustrations show an important relationship between the monthly contribution and investment period.
With a ₹5,000 monthly SIP, the projected corpus crosses ₹10 lakh in eight years under the 12% assumption. Increasing the monthly investment to ₹7,000 brings the projected corpus to ₹11.22 lakh in seven years.
This does not mean that every investor should simply increase their SIP amount. The appropriate contribution depends on income, expenses, emergency savings, existing investments, financial goals and risk tolerance.
A sustainable SIP that an investor can continue through market ups and downs may be more useful than committing to an amount that becomes difficult to maintain.
Equity, hybrid and debt funds offer different risk levels
SIPs can be used to invest in different categories of mutual funds, including equity, hybrid and debt-oriented funds.
Equity funds generally offer higher long-term return potential than fixed-income products, but they also carry greater market risk. Hybrid funds combine different asset classes, while debt-oriented funds generally focus more on fixed-income securities.
The choice should therefore be based on an investor’s financial goal, time horizon and ability to tolerate fluctuations rather than simply on an assumed return figure.
Compounding rewards consistency
The larger lesson from the ₹1 lakh-to-₹10 lakh illustration is the importance of consistency.
A person does not necessarily need a very large monthly investment to begin building wealth. Starting with an existing corpus and adding a manageable amount every month can create a structured investment habit.
Over time, returns generated on earlier investments can themselves contribute to further growth. This is the basic principle behind compounding.
However, investors should remember that compounding in market-linked investments does not follow a fixed path. Some years can deliver strong returns, while others may see negative or muted performance.
₹10 lakh is a milestone, not an endpoint
For an investor starting with ₹1 lakh, reaching ₹10 lakh can represent an important financial milestone. But the target should be considered within the larger context of financial planning.
Emergency savings, insurance, debt management, retirement planning and other financial goals should not be ignored simply to increase investments.
The SIP illustrations demonstrate what could happen under specific assumptions, but actual results will depend on market performance and the investor’s contribution pattern.
The key takeaway is that time, consistency and disciplined investing can work together to build a larger corpus. Investors should assess their own circumstances and avoid making financial decisions solely on the basis of an assumed return.
