How Does Rupee Cost Averaging Benefit Mutual Fund Investors?

07 Aug 2019

If you have been investing in equity mutual funds through a systematic investment plan (SIP), then you would have surely heard of a concept called rupee cost averaging (RCA). For example, if you spread your investments across 12 time periods in a year, then you are likely to catch lower price points; this will reduce your overall cost of holding the fund.

RCA benefits equity fund investors in four different ways.

It reduces your overall cost of holding in volatile markets

One can argue that you are better off investing in lumpsum amounts in a perpetual bull market and hold on to them. However, two problems arise here: Firstly, nobody knows the bottom; hence, the question ‘where to buy?’. Secondly, bull markets generally last for 2-3 years in a span of 10, but you need to continue investing throughout this 10-year-period. The example below will illustrate how RCA works in your favor.

As can be seen in the above table, the lumpsum investor is sitting on a loss at the end of the year, while the SIP investor acquired more units during the year due to the power of RCA. That is how RCA makes volatility work in favor of the SIP investor.

SIP instills investing discipline

In the long run, investing is less about great stock selection and more about discipline. The longer you successfully invest a fixed amount on a regular basis, the more wealth you are going to create over a longer period. The table below captures how the wealth ratio goes up drastically by maintaining disciplined investing over a longer period of time.

The power of discipline in investing is a result of RCA. As the time frame of this discipline increases, you can see the wealth ratio also going up substantially.

It saves you from having to time the market

It is not only hard to time the market and even more impossible to do so on a constant basis. Anyone who says that he can catch the tops and the bottoms of the market is either a God or a liar. What RCA does is that it saves you the hassle of trying to find the bottom and the top of the market. It has also been observed that market timing does not really add too much value to your returns over longer periods of time. Instead, if you continue to invest in equities in a disciplined manner, then the impact on your wealth is going to be much greater. That is what RCA helps you to achieve.

At a more practical level, the reason RCA works is that it synchronizes with your inflows. Hence, you are not forced to terminate your SIPs in the middle. This is one of the most important reasons why RCA is successful!

    This article claims RJio was given a "Backdoor Entry" into the 4G Based Voice Routing. The peculiar aspect is without the Voice License, Rjio would have been a mere ISP. With the license, it is now a holistic communications service provider, with ability to exponentially scale the bouquet of products. The events indicate it was meticulously planned way before the auctions because the auctions were clear on the agenda: 4G for internet only.
