SIP vs Lumpsum: What’s the Difference?

You’ve finally decided to invest in mutual funds. But now the confusing part, should you go with a SIP or invest a lump sum? This is one of the most common questions every beginner faces. Here we will discuss SIP vs Lumpsum.

Now, imagine you would rather pay your phone bill in small monthly amounts (SIP), or pay for the whole year in one shot (Lumpsum)? Both options work, but which one’s better for you? When it comes to investing, choosing between SIP and lump sum can impact how your money grows, how much risk you take, and how easy it is to stay consistent.

What is SIP?

SIP or Systematic Investment Plan allows the investor to invest the fund in a fixed amount at regular intervals, such as weekly, monthly, or quarterly-into a selected mutual fund scheme. 

In simple terms, it’s like ordering a Netflix subscription for your investments. You pay a fixed amount every month, and that money goes into mutual funds.

For example, let’s say Ramesh decides to invest ₹5,000 every month into a mutual fund through SIP.

So, in 1 year:

• He invests ₹5,000 × 12 = ₹60,000.
• But he doesn’t pay it all at once. He spreads it out month by month.

Over time, thanks to compounding and rupee cost averaging, his money grows.

Real-Life Example

Let's take a Scenario,

Scenario
1st scenario	Where, The monthly investment is ₹10,000 The expected return is 12% p.a. The investment timeline is 6 years.
2nd scenario	Where, The monthly investment is ₹10,000 The expected return is 12% p.a. The investment timeline is 12 years.
3rd scenario	Where, The monthly investment is ₹10,000 The expected return is 12% p.a. The investment timeline is 18 years.
4th scenario	Where,  The monthly investment is ₹10,000 The expected return is 12% p.a. The investment timeline is 24 years.

The returns,

• After the 1st 6 years of investment, ₹3,37,570
• 12 years returns, ₹17,82,522
• 18 years returns, ₹54,94,392
• 24 years returns, ₹1,38,46,872

So by investing ₹10,000 monthly(total invested ₹28,80,000) in a very disciplined manner, where the maturity value you have is ₹1,67,26,872, after 24 years.

For better understanding, you can use the SIP calculator to help you understand the magic of compounding.

How Does SIP Work?

Here's how SIP works:

• The money automatically gets deducted from your bank account every month (or week/quarter, depending on what you choose).
• That amount is used to buy units of a mutual fund.
• If the market is down, mutual fund prices (called NAV) are lower, so you get more units.
• If the market is up, NAV is higher, so you get fewer units.

This process is called rupee cost averaging. It simply means you don’t have to worry about timing the market. Over time, the ups and downs balance out your buying price.

Benefits of SIP

Here are the benefits of  SIP:

• Budget-friendly: Start with as low as ₹500/month.
• Disciplined investing: You don’t need to time the market.
• Reduces risk: You invest over time, so market ups and downs average out.
• Easy to automate: Set it and forget it.
• Power of compounding: Returns earn returns.

What is a Lumpsum?

A lumpsum investment involves investing a large amount of funds in one go into a mutual fund scheme. In simple terms, lumpsum means investing a large amount at once.

Imagine you got a Diwali bonus of ₹1,00,000. Instead of letting it sit in your savings account, you invest the full ₹1,00,000 in one go.

Real-Life Example

Let's take a Scenario,

Scenario
1st scenario	Where, The monthly investment is ₹28,80,000 The expected return is 12% p.a. The investment timeline is 6 years.
2nd scenario	Where, The monthly investment is ₹0 The expected return is 12% p.a. The investment timeline is 12 years.
3rd scenario	Where, The monthly investment is ₹0 The expected return is 12% p.a. The investment timeline is 18 years.
4th scenario	Where,  The monthly investment is ₹0 The expected return is 12% p.a. The investment timeline is 24 years.

The returns,

• After the 1st 6 years of investment, ₹56,84,609
• 12 years returns, ₹1,12,20,411
• 18 years returns, ₹2,21,47,101
• 24 years returns, ₹4,37,14,451

So by investing ₹28,80,000 in a very disciplined manner, where the maturity value you have is ₹4,37,14,451, after 24 years.

How Does Lumpsum Work?

Here's how Lumpsum works:

• You invest all the money at once.
• That money is used to buy units based on the NAV (price per unit) on that specific day.
• If the market goes up after you invest, your returns can grow fast.
• But if the market goes down right after, your investment can also drop sharply.

Benefits of a Lumpsum

Here are the benefits of a Lumpsum:

• Good for surplus cash: Ideal when you have a big amount to invest.
• Faster growth if timed well: If the market is low and you invest, gains can be huge.
• One-time effort: No monthly reminders or debits.

Key Difference Between SIP Vs Lumpsum

Here are the key differences between SIP vs Lumpsum:

Which One Should You Choose?

Choose according to your preferences:

Choose SIP If:	Choose Lumpsum If:
You earn monthly (salary, business income)  You’re new to mutual funds. You want to invest small amounts. You’re bad at saving and need structure.	You got a bonus, inheritance, or FD maturity. You understand markets (or are okay with risk). You have a long-term goal, and the market is low.

You can even do both, use SIP for discipline and Lumpsum when you have extra funds.
