Rs 15,000 SIP Vs Rs 2 Lakh Lump Sum: Which Investment Route Can Build A Rs 2 Crore Corpus Faster?

For many investors, building a corpus of Rs 2 crore represents a significant financial milestone. Such an amount can help fund major life goals, including retirement planning, children's higher education or creating long-term financial security. Mutual funds remain a popular choice for pursuing these objectives, with investors typically choosing between regular investments through a Systematic Investment Plan (SIP) or making a one-time lump sum investment. A comparison based on an assumed annual return of 12% highlights how these two approaches differ in terms of time, investment amount and wealth creation.

Two Different Paths To Long-Term Wealth

Although both SIPs and lump sum investments are designed to generate long-term returns, they work in fundamentally different ways.

A Systematic Investment Plan allows investors to invest a fixed amount at regular intervals, most commonly every month. According to investment experts, this approach encourages financial discipline and helps spread investments across different market conditions. It also makes mutual fund investing accessible without requiring a large amount upfront.


A lump sum investment, by contrast, involves investing a sizeable amount in a single transaction. The entire amount starts compounding immediately, but the investment's performance is more dependent on market conditions prevailing at the time of investment.

The Role Of Compounding

Compounding is one of the biggest drivers of long-term wealth creation .


According to financial planners, returns generated during the investment period are reinvested, allowing future returns to be earned not only on the original investment but also on the accumulated gains. The longer money remains invested, the greater the impact of compounding.

For this comparison, an annual return of 12% has been assumed, a figure commonly used for long-term mutual fund illustrations. However, actual returns can vary depending on market performance.

How A Rs 15,000 Monthly SIP Performs

Consider an investor contributing Rs 15,000 every month through a mutual fund SIP.

At an assumed annual return of 12%, maintaining this investment consistently for around 23 years can potentially build a corpus of approximately Rs 2 crore.


During this period:

  • Monthly investment: Rs 15,000
  • Investment period: 23 years
  • Total amount invested: Rs 41.4 lakh
  • Estimated wealth created through returns: Around Rs 1.59 crore
  • Estimated maturity value: Around Rs 2 crore
The illustration demonstrates how disciplined monthly investing, combined with the long-term effect of compounding, can generate a corpus significantly larger than the total amount invested.

What Happens With A Rs 2 Lakh Lump Sum?

Now consider a one-time investment of Rs 2 lakh invested at the same assumed annual return of 12%.

Without any further contributions, the investment is projected to grow to approximately Rs 2.08 crore over about 41 years.

The estimated figures are:


  • Initial investment: Rs 2 lakh
  • Investment period: 41 years
  • Estimated returns: Around Rs 2.06 crore
  • Estimated maturity value: Around Rs 2.08 crore
Unlike the SIP, this strategy depends entirely on the long-term growth of the original investment, since no additional money is invested after the initial contribution.

Why Does The SIP Reach The Target Earlier?

At first glance, it may seem surprising that a monthly SIP reaches the Rs 2 crore milestone much sooner despite starting with a much smaller investment.

According to experts, the explanation lies in the regular addition of fresh capital. Every monthly SIP instalment increases the total invested amount, while the earlier contributions continue earning returns over many years.

Although each SIP instalment receives a different investment horizon, the combined effect of continuous investing and compounding enables the corpus to grow more rapidly than a relatively small lump sum left to compound on its own.

The lump sum investment benefits from having the entire amount invested from the very beginning, but without further contributions, it takes considerably longer to reach the same financial goal.
