Systematic Investment Plan' (SIP) is an investment vehicle offered by mutual funds to investors, allowing them to invest small amounts periodically instead of lump sums. The frequency of investment is usually weekly, monthly or quarterly based on the clients.

The strategy claims to free the investors from speculating in volatile markets by Rupee cost averaging. As the investor is getting more units when the price is low and fewer units when the price is high, in the long run, the average cost per unit is supposed to be lower.
