01
What are SIP and lump sum?
A Systematic Investment Plan (SIP) allows you to invest a fixed amount regularly, typically every month, in a mutual fund scheme. A lump sum investment means investing a large amount at once.
Both approaches invest in the same mutual funds. The difference is only in how and when you invest the money.
SIP and lump sum are not different products. They are two ways of investing in mutual funds.
02
How do they work?
SIP
Invest a fixed amount at regular intervals, regardless of market levels.
Lump sum
Invest the entire amount at once and stay invested.
A SIP purchases more units when prices are low and fewer units when prices are high. This is known as rupee cost averaging.
A lump sum investment buys units only once, at the current market price. Your entire investment is exposed to market movements from that point onwards.
SIP averages your purchase cost over time. A lump sum puts all your money to work immediately.

How market conditions can affect the outcome
Put a lump sum in just before a good stretch and it will beat drip-feeding the same money — all of it was working the whole time. Put it in just before a bad one and it will lag, for exactly the same reason.
A SIP gives up both extremes. You will not catch the bottom, and you will not put everything in at the top either.
Neither approach is always better. The outcome depends on how markets perform after you invest.

05
When a SIP may be more suitable
- You have a regular income.
- You do not have a large amount to invest right now.
- You are unsure about short-term market movements.
- You want to build an investment habit.
- You are investing for long-term goals.
06
When a lump sum may be more suitable
- You have a large amount available to invest.
- You are comfortable with short-term market fluctuations.
- You want to invest early and stay invested for the long term.
- You believe markets are reasonably valued.
- You do not need the money in the near term.
07
Can you combine both?
Yes. Many investors use a combination of both approaches.
For example, you may invest a part of a lump sum immediately and the rest through an SIP over the next few months. This is sometimes called a staggered investment approach.
There is no rule that you must choose only one. A combination can also be a sensible option.
