The two ways to invest in Mutual Funds are SIP and Lumpsum.
SIP (Systematic Investment Plan)
SIP allows you to invest a fixed sum at regular intervals. SIP is one of the most recommended ways to invest in Mutual Fund schemes as it is convenient. It also helps you average out the cost at which you buy the units of these funds.
When you make a one-time investment, it is called a lump sum. Lumpsum investments are generally done when people have got a big sum of money like bonuses or payments from a sale of an asset.
