What Is Rupee Cost Averaging and How Does It Work?

A Systematic Investment Plan (SIP) is one of India’s most popular investment modes. This is due to its capability to beat inflation and offer considerable returns in the long term. One of the most common benefits of SIPs is ‘Rupee Cost Averaging’, which allows investors to profit from market volatility. 

The following sections will cover the concept of rupee cost averaging, its characteristics, benefits, uses and working principles.

What Is an SIP (Systematic Investment Plan)?

Before learning about rupee cost averaging, it is essential to know what an SIP is and what it has to offer to an investor.

An SIP (Systematic Investment Plan) is an investment method that enables an individual to invest money in small quantities periodically in mutual funds. This happens via recurring payments. The payment intervals may be weekly, monthly, quarterly, semi-annually or annually.

In an SIP, the payments are spread throughout the investment tenure. Therefore, one does not require a lump sum of money to invest in SIPs. As a result, they are an excellent option for people with low-risk appetites and long-term investment goals.

One can start SIPs from as low as ₹500 per month. This makes them a feasible investment option for those who cannot afford to invest via a lump sum. In addition, regular payments help instil a sense of financial responsibility in the investors.

Next, we will discuss rupee cost averaging in SIPs.

Concept of Rupee Cost Averaging

Rupee Cost Averaging is a concept based on averaging the cost at which an investor buys units in a mutual fund scheme. More so, it helps make a profit by balancing out the market risks.

When investing via SIPs, a fixed sum of money is invested irrespective of the fund’s NAV per unit – the lower the NAV, the more the number of units purchased and vice versa.

Since the performances of mutual funds are reliant upon the equity markets, they are subject to volatility and risk. Therefore, it is vital for individuals to remain invested even throughout market downfalls to reap the benefits of rupee cost averaging.

Rupee Cost Averaging is based on time commitment and not investment frequency. This means if an investor is able to remain invested throughout a long tenure, they will be able to gain significant wealth.

How Does Rupee Cost Averaging Work?

The working principle of rupee cost averaging is simple. When an investor invests a fixed amount of money at regular intervals, they receive more fund units when the fund’s NAV is low and less when it is high.

SIPs gain significant advantages from rupee cost averaging. Due to the consistent investments made, the investor ends up buying more units at lesser prices and fewer units at higher prices. This helps in reducing the average cost per unit over the investment tenure. Hence, the average unit cost will be less than the average unit sale price.

For a better understanding of how rupee cost averaging works, let us refer to the example provided below.

Suppose an investor decides to put a sum of ₹4,000 each month in an SIP for a tenure of 6 months. The units allocated would be:

MonthSIP AmountNAV per UnitNumber of Units Allocated
January 2022₹4,000₹5671.42
February 2022₹4,000₹9641.67
March 2022₹4,000₹8447.62
April 2022₹4,000₹6858.82
May 2022₹4,000₹8050
June 2022₹4,000₹6066.67
Months: 6Total: ₹24,000Average NAV per unit: ₹71.38Total: 336.20

From the above table, we can see that the total investment is ₹24,000, with the total number of NAV units purchased being 336.30. Hence, the average NAV unit price is ₹71.38.

If the entire amount were invested in February 2022, the number of units bought would be 250, which is significantly less than 336.20.

Hence, rupee cost averaging is crucial in balancing out market fluctuations during the investment tenure. This makes it a cost-effective way of investing in mutual funds.

Uses of Rupee Cost Averaging

The following are some additional uses of rupee cost averaging:

  • In dividend reinvestment plans, rupee cost averaging helps in the calculation of the particular amount one must invest over a time period.
  • It works well both in volatile markets and bull markets.
  • Rupee cost averaging behaves as a safety net against market volatility in equity investments.

Are SIPs Helpful in Bull and Bear Markets?

The concept of rupee cost averaging works best in volatile markets as it helps to minimise losses. Moreover, as SIP investments ensure that you purchase fewer units in bull markets, you end up buying fund units at a lower average price. 

In bull markets, the price of a stock continuously increases over a time period. However, even during such times, there may be short temporary downturns. Investing in small amounts during these downturns helps in reducing aggregate costs.

Rupee cost averaging is really useful during such downturns as it makes you purchase less when prices are high and more when prices reduce.

Final Word

Investing in SIPs offers the benefit of rupee cost averaging, which creates financial discipline in your life. It helps in reducing speculations and automates the investing process. The returns gained from investing this way are achieved with less effort and more consistency. It is a necessary tool in unpredictable markets.
