Mutual Funds SIP vs Lump Sum: How Rupee Cost Averaging Works and Where It Falls Short
Investors may choose from several ways of investing in the mutual fund schemes, with the Systematic Investment Plans (SIPs) and lump sum investment being two options amongst them. Although the two methods of investments give access to the market linked investment schemes, the way of investing varies in both the cases. Investors have to invest money on a periodic basis in the case of the SIP, but there is investment of large sums at once in the case of lump sum investment.
What is a Mutual Fund SIP?
Under the mutual fund SIP , the investor makes investments in the mutual fund scheme in equal sums at specific intervals. It can be done weekly or even monthly.
As an illustration, an investor may decide to invest ₹3,000 per month in an equity mutual fund scheme. This will be done automatically based on the availability of the bank balance and mandate.
The units acquired will depend on the NAV of the mutual fund scheme on the day of investment.
What is Rupee Cost Averaging?
Rupee cost averaging is a method through which investors purchase mutual fund units at different NAVs over time by investing a fixed amount regularly.
It is one of the key features associated with SIP investments.
Consider the following example:
An investor starts a monthly SIP of ₹2,000 in a mutual fund.
The investor purchases 405 units over four months.
The average purchase cost per unit is approximately ₹19.75, calculated by dividing the total investment of ₹8,000 by 405 units.
In this example, the investor purchases more units when the NAV falls and fewer when it rises. This is how rupee cost averaging works.
However, it does not guarantee profits or protect investors from market losses. The value of the accumulated units can still decline if the fund's underlying investments perform poorly.
How Does Lump Sum Mutual Fund Investment Work?
Under the lump sum investment technique, a large amount is invested in a mutual fund scheme at once.
Suppose an investor has ₹60,000 which he wants to invest in a stock mutual fund scheme.
At the time of investment, let us suppose the NAV was ₹30, so he gets 2,000 units for ₹60,000.
In contrast to the MF SIP, the whole amount will be affected by changes in the market from the date of investment. In case there is an upward movement in the market after the date of investment, it can bring gains for the investor. Conversely, in case there is a downward movement in the market, the investment can lose its value.
Mutual Funds SIP vs Lump Sum: Key Differences
Both methods allow investors to participate in mutual fund schemes, but their investment approaches differ.
The choice depends on the investor's financial position, investment horizon and risk tolerance. Neither method guarantees better returns in every market condition.
Where Does Rupee Cost Averaging Fall Short?
Despite its benefits in timing, rupee cost averaging has some drawbacks.
- It does not protect from market loss: If there is a poor performance of the mutual fund scheme, then the investment value accumulated could fall because of regular investments made in it.
- It does not perform better than lump sum in case of rising markets: In case of rising markets, investing in lump sum could offer more exposure to the market.
- It does not guarantee a lower average cost: The average purchase price depends on NAV movements throughout the investment period.
- It cannot replace fund research: Investing regularly in a poorly performing scheme does not automatically improve its prospects.
Conclusion
SIP and lump sum investments offer different ways to participate in mutual funds. While SIPs support regular investing and rupee cost averaging, lump sum investments provide immediate market exposure. However, neither approach eliminates market risk or guarantees returns. Investors should consider their available funds, financial goals and investment horizon before choosing a method.
