SIP works on the basic concept of regularity of investments. It works like a recurring investment of a specified amount, which gets debited directly from an investor’s bank account at select intervals.
Once the investor pays the SIP amount, the mutual fund house allocates you with a certain number of units of the scheme you have chosen to invest in, depending upon the scheme’s Net Asset Value (NAV) for the day. With every SIP installment, the investor gains additional units of the scheme.
Since, every time the scheme units are bought at different rates, therefore, with the same SIP amount invested at regular intervals, the investor’s money buys him/her fewer units of the mutual fund scheme during rising markets and more units during declining markets.
Thus, a SIP enables you to lower the average cost of your investment and reduce the risk of your investment by spreading your purchase price over time. This is known as rupee cost averaging.
Moreover, a SIP enables you to regularly increase your investment amount by a fixed amount and get the benefit of compounding as you earn returns on the returns generated by your investment. This is called power of compounding.
