Rs 5,000 Monthly SIP Vs Rs 5 Lakh Lump Sum: Which Mutual Fund Investment Can Build A Bigger Corpus In 10 Years?

Newspoint
Choosing between a systematic investment plan (SIP) and a lump sum investment is a common dilemma for mutual fund investors. While one approach spreads contributions across several months, the other puts the entire amount into the market at once. Both strategies have different advantages, depending on an investor's financial position and market conditions.

But which approach could create a bigger corpus over 10 years? A comparison of a Rs 5,000 monthly SIP and a Rs 5 lakh one-time investment offers some useful insights.

SIP Vs Lump Sum: Understanding The Two Investment Methods

Before comparing potential returns, investors should understand how these two mutual fund investment methods work.


A SIP allows individuals to invest a predetermined amount at regular intervals, usually every month. Investors can start with relatively small contributions and increase their investments as their income grows.

For example, someone investing Rs 5,000 every month will gradually build a mutual fund portfolio without needing a large amount of money at the beginning.


One of the main advantages of this approach is rupee cost averaging. Since investments happen at different market levels, investors purchase more mutual fund units when prices are lower and fewer units when prices are higher.

This can help reduce the impact of market timing on the average purchase cost. However, it does not eliminate market risk or guarantee positive returns.

A lump sum investment follows a different approach. Here, the investor puts the entire available amount into a mutual fund in one transaction.

For instance, an individual with Rs 5 lakh in savings can invest the entire amount at once rather than distributing it over several months.


The full investment gets market exposure immediately. This can be advantageous when markets rise over the investment period, as the entire amount participates in the growth from the beginning.

However, an immediate market decline can also affect the entire investment. Consequently, the timing of entry can have a considerable influence on the final outcome.

Rs 5,000 Monthly SIP For 10 Years: How Much Can You Accumulate?

A monthly SIP can help investors develop a disciplined approach towards long-term investing. Even a relatively small contribution can grow into a substantial amount when maintained over several years.

Consider an investor who puts Rs 5,000 into a mutual fund every month for 10 years, assuming an annualised return of 12%.

The estimated investment calculation is as follows:


  • Monthly SIP: Rs 5,000
  • Investment duration: 10 years
  • Assumed annual return: 12%
  • Total amount invested: Rs 6,00,000
  • Estimated capital gains: Rs 5,61,695
  • Estimated final corpus: Rs 11,61,695
Under these assumptions, the investor contributes Rs 6 lakh over 120 months. The remaining amount represents the estimated growth generated by the investment.

The advantage of this approach is that investors do not need to arrange a substantial amount at the beginning. They can invest according to their monthly income and financial commitments.

However, SIP returns are not fixed. The actual corpus will depend on market performance, the mutual fund scheme selected and the timing of individual instalments.

Rs 5 Lakh Lump Sum For 10 Years: What Could Be The Final Value?

Investors who already have a substantial amount available may consider putting it into a mutual fund through a one-time investment.

Suppose an individual invests Rs 5 lakh in a mutual fund and remains invested for 10 years, assuming the same annualised return of 12%.


The estimated calculation would look like this:

  • Initial investment: Rs 5,00,000
  • Investment duration: 10 years
  • Assumed annual return: 12%
  • Total amount invested: Rs 5,00,000
  • Estimated capital gains: Rs 10,52,924
  • Estimated final corpus: Rs 15,52,924
At the assumed rate of return, the investment could grow to approximately Rs 15.53 lakh after a decade.

The entire principal receives market exposure from the beginning, allowing the investment to benefit from compounding throughout the 10-year period.

This is one reason lump sum investing can produce a higher corpus when markets perform favourably over the investment horizon.

However, the outcome can be different if the investor enters the market just before a prolonged downturn. Since the entire amount is invested at once, an early decline can have a significant impact on the portfolio.


SIP Vs Lump Sum: Comparing The Estimated Returns

The above calculations show that the Rs 5 lakh lump sum investment could accumulate a larger amount than the Rs 5,000 monthly SIP under the assumed return conditions.

However, there is an important difference that investors should not overlook.

The SIP investor contributes Rs 6 lakh over 10 years, whereas the lump sum investor puts in only Rs 5 lakh. Therefore, these are not equal-investment comparisons.

The lump sum calculation also assumes that the entire Rs 5 lakh remains invested for the full decade. In the SIP calculation, money enters the market gradually, meaning every instalment has a different investment period.

ParticularsMonthly SIPLump Sum
Investment amountRs 5,000 monthlyRs 5 lakh once
Investment period10 years10 years
Total contributionRs 6 lakhRs 5 lakh
Assumed annual return12%12%
Estimated final corpusRs 11.62 lakhRs 15.53 lakh
The difference in the final corpus is therefore influenced by both the investment method and the timing at which money enters the market.


To make a fair comparison, investors should also compare the two methods using the same total investment amount and clearly defined investment dates.

Which Investment Strategy Should You Choose?

There is no universal answer to whether SIP or lump sum investing is better. The appropriate option depends on how much money an individual has available, their investment experience and their ability to tolerate market fluctuations.

According to financial experts, SIPs can be suitable for salaried individuals and investors who prefer to invest smaller amounts regularly. They also help establish a consistent investment habit without requiring a large initial contribution.

Lump sum investing may appeal to individuals who already have surplus funds and a sufficiently long investment horizon. However, they should be comfortable with the possibility of short-term market volatility.

Investors who have a large amount available but are uncomfortable investing everything at once can also consider deploying their money gradually. The decision should take into account their financial goals, risk tolerance and investment strategy.

It is equally important to select a mutual fund based on its investment objective, portfolio composition, risk profile and suitability rather than choosing a scheme simply because it has delivered impressive historical returns.

Do Not Assume 12% Returns Are Guaranteed

The calculations above use an assumed annual return of 12% to illustrate how different investment methods can affect wealth creation.

Mutual funds, particularly equity-oriented schemes, are market-linked products. Their returns fluctuate depending on stock market movements, economic conditions, fund management decisions and other factors.

A fund that generates 12% annualised returns over one period may deliver considerably different results over another. Past performance cannot guarantee similar returns in the future.

Investors should also remember that the estimated figures do not account for applicable taxes and other potential costs.


Before committing money, assess your financial goals, investment horizon and ability to withstand losses. Consulting a qualified financial adviser can also help determine which investment strategy is appropriate for your circumstances.

Ultimately, consistency, suitable asset allocation and a clear understanding of market risks are more important than choosing an investment method solely on the basis of an attractive projected corpus.
