SIP vs. Lump Sum: Choosing the Right Investment Method

In this article, we will discuss

When it comes to maximising gains from the stock market, there is no beating mutual funds. They facilitate portfolio diversification, exposure to several asset classes and industrial sectors and the benefit of professional management. However, have you thought of the better way to invest in these schemes? Well, there are essentially two ways to do so – SIP and lump sum. But which one should you choose? Find out the differences between them, along with the answer to this question, by reading this blog.

What is SIP?

A Systematic Investment Plan (SIP) is a phased investment method. It allows you to invest in a mutual fund scheme by investing a fixed amount of money, at regular intervals, over a time period of your choice. Given its sheer flexibility, SIPs are one of the most popular mutual funds investment methods. You can start with a SIP amount as low as ₹500 and scale up your investment with time. Now, most schemes allow you to make monthly contributions. However, there are also some which facilitate daily, weekly, quarterly and yearly instalments. Investing via SIPs also serves as a savings plan. It helps create a disciplined investment habit among individuals, enabling them to avail a substantial maturity corpus without putting a strain on their finances.

What is Lump Sum?

As the name suggests, this method allows you to invest a lump sum amount in a mutual fund scheme. This is an excellent tactic for investing money gained from matured FD schemes, policies, bonuses, inheritance and more. You can deposit the entire amount in one mutual fund or multiple schemes of your choice. As per latest news, the Securities and Exchange Board of India (SEBI) has made it mandatory for AMCs to offer mutual funds with a minimum lump sum amount of ₹100. However, this factor may differ across schemes. Additionally, there is no maximum investment threshold.

Advantages of Investing via SIP

Here are some of the advantages of investing in mutual funds via SIPs:

  • Rupee Cost Averaging

One of the biggest advantages of SIPs is rupee cost averaging. It enables you to get more fund units when the prices of the assets in the portfolio are low or bearish. Your investments stay safe even during times of market volatility, enabling you to get stable returns in the long term. Moreover, this nullifies the need for timing the market before starting a mutual fund investment.

  • Flexibility

Apart from choosing your regular investment amount, SIPs also allow you to pause, stop and change your monthly contributions as per your needs. Additionally, if required, you can redeem some of your units and still continue with the plan without affecting your investment goals.

  • Portfolio Diversification

With SIPs, diversifying your portfolio is a walk in the park. You can divide the amount you wish to invest among different types of schemes like – equity, debt, hybrid funds, etc., and enjoy diversification across different sectors and asset classes.

  • Compounded Returns

SIPs are also a great way to avail compounded returns. The interest that you earn gets added to the principal amount, and with a systematic approach of investment, you can gain lucrative compounded returns in the long run.  

  • Suitable for New Investors

If you are new to investing in the stock market, opting for systematic investment plans is an effective way to test out the water before trying something else. Additionally, as most schemes are actively managed by fund managers, you have less chance of incurring losses due to market fluctuations.

Advantages of Lump Sum Investment

These are the benefits of making lump sum investments in mutual funds:

  • Tax Benefits

Lump sum investments are a great choice if you are willing to avail tax benefits. You can deposit your corpus in an Equity Linked Saving Scheme (ELSS) and avail deductions of up to ₹1.5 lakh within a financial year under Section 80C of the Income Tax Act. However, remember that tax-saving schemes come with a 3-year lock-in period.

  • Ideal for Self-Employed Individuals

Self-employed individuals like businessmen or people who offer their services to various clients do not have a regular monthly income. For them, the lump sum investment method can be the better choice. They can make a one-time deposit whenever they feel feasible and plan for the next one as per their investment objective.

  • Useful in Case of Short-Term Debt Funds

If you are planning to invest in short-term debt funds, choosing a lump sum investment may be the better for you. The reason being such schemes have an investment horizon of 1 to 3 years. So, opting for SIPs, in this case, will not yield as great a return as its lump sum counterpart.

Key Differences Between SIP and Lump Sum

To choose between SIP and lump sum, you need to know their key points of difference. They are mentioned in the table below:

Parameters SIP Lump sum 
Market Entry Can be done at any time due to rupee cost averaging benefits. Preferable during bearish markets to get units at a lower cost.
Flexibility More flexible in comparison to lump sum investments as they can be modified as per the investor’s financial condition. Flexibility is not available as it is a one-time investment option.
Volatility Not much responsive to volatility due to rupee cost averaging. Highly responsive to market volatility.

What Should You Consider Before Choosing SIP vs Lump Sum?

Here are some factors which you must keep in mind while choosing between SIP and lump sum:

  • Risk Appetite

Whether you choose SIP or lump sum, both options come with a certain level of risk. In case of SIPs, you can pause your investment and continue with it when you feel that the market is in your favour. However, for a lump sum, once you deposit your money, there is no way to pause the investment other than redeeming it.   

  • Market Conditions at the Time of Withdrawal

The returns that you get from both SIP and lump sum depend on the market conditions at the time of redemption. Due to rupee cost averaging benefits, SIPs can provide you stable returns even in unfavourable market conditions. However, in case the market is favourable, chances of profits are greater in case of lump sum investments.

  • Investment Amount

Determining the investment before going for a systematic investment plan or a lump sum is essential. For SIPs, experts advise selecting an amount which you can pay at regular intervals without fail. Whereas, in case of a lump sum, it is suggestible to allocate a sum which you can afford to lose without straining your overall finances.

About SIP Calculator

When starting a SIP, calculating the monthly instalment amount to meet your expected maturity corpus can be hectic. Thus, to make things easier, consider using a SIP calculator. It is an online tool which can help you determine an estimated value of your total investment depending on your SIP amount. To use it, simply enter your monthly investment amount, tenure and expected return rate. The system will display your total investment amount, estimated returns and the estimated total value of your investment. Now, in case you want to invest via a lump sum amount, you simply need to use the lump sum calculator. Just enter your total investment amount, expected return rate and time period. The platform will display your estimated returns, along with your total investment value.


In a nutshell, SIPs are more suitable for new investors or individuals who do not have that much time to analyse market movements. Its aspect of rupee cost averaging can help you avail stable returns by reducing the effects of volatility. Alternatively, lump sum investment methods are apt for experienced investors who know the ways to time the market in order to book profits.
