I am a newbie.I have read quite some articles on SIP. I wanted to know how does a person get his money when investing in SIP. For e.x. when a person invests in FD for a year, he knows that he will get his money in a year, when he invests in PPF, after 15 years, he will get the money. Likewise, if I invest money monthly in SIP , then when will I get the money back? Is it paid lumpsum?
