What is SIP?

SIP, meaning “Systematic Investment Plan,” is a process of investing in various mutual fund schemes. The process allows investors to make a fixed periodic investment in a selected mutual fund scheme.

The SIP amount is fixed at the time of making a mutual fund investment. For making any changes in the fixed amount, you need to request your fund manager.

The minimum SIP amount varies from scheme to scheme. The minimum amount is Rs. 500, and there is no upper limit. Hence, you can choose any amount for SIP. But the minimum amount will differ from one mutual fund house to another and from one mutual fund scheme to another.

Systematic Investment Plan is periodic. This means once you have selected the Systematic Investment Plan frequency, the amount will get auto-debited from your bank account at the same time interval.

The SIP periods can be weekly, monthly, or quarterly.

Before choosing any Systematic Investment Plan, you should ensure that you have the fixed amount in your bank account at the selected SIP period.

How SIP Works?

The systematic investment plan works in three stages. This is how it works;

Stage 1 – SIP Mandate

Investors need to give a mandate (authorization to invest via SIPs) to invest in mutual fund schemes.

This can be done online by selecting the “Systematic Investment Plan” option while you are investing. But for the offline method, you need to fill a mandate form and submit it along with the application form.

Also, on the form, you need to indicate your choice for the date (on which the amount will be invested) and the amount.

If done subsequently, then the mandate forms can be submitted online through your mutual fund account.

In the offline method, you need to submit the mandate to the office of the mutual fund house, Karvy, or CAMS.

Stage 2 – Auto Debit/ ECS

When you give a mandate, the fund house auto-debits your bank account for the indicated SIP amount through standing instruction. The funds are then transferred through ECS for investing in a mutual fund scheme.

Likewise, the subsequent investment amounts will also be auto-debited at your indicated SIP interval. This way, you need not worry about missing any payments.

Stage 3 – Allotment of Mutual Fund Units

The SIP amount debited from your bank account is utilized for purchasing mutual fund units. And, you are allotted mutual fund units at the closing NAV of the day of money transfer or realization of the cheque.

Let us understand how Systematic Investment Plans SIP works with the help of an example.

Suppose you start an sip of Rs. 1000 on the 5th of a particular month.

Then Rs. 1000 will be auto-debited from your specified bank account on the 5th of every month and will be utilized in buying units of the mutual fund. Also, the mutual fund units will be purchased at that day’s closing NAV.

With every payment, you will receive units of the particular mutual fund scheme, which will get added to your mutual fund account.

Hence, SIP is like indicating “How Much” and “How Often” you will invest in a mutual fund scheme.

Types of SIP

Apart from regular SIP, mutual fund investors have four different types of SIP for different purposes. The types are as under;

1. Top-up Systematic Investment Plan

Top-up SIP is also known as “Step-up SIP.” SIP Topup helps you increase the installment amount.

You can indicate the amount of increment and when to increase at the time of making mutual fund investment.

For example, while investing in mutual funds, you can decide a SIP amount as low as Rs. 500 for five years without any changes during the course of the fund.

Through the Step-Up SIP option, you can increase the amount being invested every month by 10% or Rs.100.

Step-up SIP is helpful in a situation where you get annual salary hikes and periodic bonuses that can be invested in mutual funds.

Therefore, with an increment in your income, you have the option to invest a higher amount. The SIP Topup plan increases the investment amount at regular intervals.

2. Flexible Systematic Investment Plan

On the other hand, if you have a variable income or surplus investment fund that varies from month to month, then flexible SIP is a better option.

A flexible SIP is also known as “Flexi SIP.” The Flexi SIP gives you the flexibility to vary the investment amount before every SIP installment.

Flexi SIP investors can choose the exact installment amount seven days prior to the SIP installment due date.

However, you need to specify a minimum amount in advance to ensure mutual fund investments.

The best part of the Flexi SIP is that you have the choice to pay different SIP amounts every time. You can decide the amount according to your cash flow before the time of payment. You have the advantage of not being bound to pay a fixed amount every month.

3. Perpetual Systematic Investment Plan

Unlike regular SIP that has a fixed SIP term of say 1, 3, or 5 years, “Perpetual SIP” plans do not have any end date. Perpetual SIP continues forever until you choose to stop or redeem your mutual fund investments.

You can continue with Perpetual SIP till your investment objective is not fulfilled. 

4. Trigger Systematic Investment Plan

Trigger SIP has a unique feature of automatic mutual fund investment/ redemption or action on the occurrence of a certain event.

For example, you can set a Trigger SIP for buying a particular mutual fund scheme when the NAV touches a specific level.

Here trigger action is to buy the mutual fund units, and the trigger event is the specified NAV level.

When you set a Trigger SIP, the system waits for the trigger event to happen. When the event occurs, a buy instruction is generated, and the purchase transaction happens.

Likewise, you can set trigger action for selling units or switching mutual fund investments.

Trigger SIPs can be misused for speculation and are like a double-edged sword. A wrong trigger has the potential to ruin an investment; hence they are discouraged.

Benefits of SIP Investment

1. Planned and Disciplined Investing Approach

A systematic investment plan ensures that you are investing in mutual funds in a planned and regular manner.

The approach helps in developing a habit of saving and disciplined investment that is essential for achieving financial goals and long-term wealth creation. Starting a Systematic Investment Plan allows an investor to invest regularly in the mutual funds (equity schemes) of their choice.

3. Cost Averaging

When you make a SIP investment, you regularly invest in mutual funds (equity schemes) over time, irrespective of market conditions.

When the markets are down, you get more units as compared to when the market is high. In the long run, SIP investment evens out the purchase cost of your mutual fund units. In other words, Sips or systematic investment plans help in rupee cost averaging and reduce cost per unit. 

Rupee cost averaging means when a fixed amount is invested regularly over a period of time through different market cycles, you can get more units when the price is low and fewer units when the price is high. This reduces the average cost per unit of investment in the long run.

4. Low-cost Investment

The investment cost can be as small as Rs. 500 per month.

In Rs 500 you get to invest in government securities, T-bills, shares, and bonds of different companies, which is impossible if you had made an individual investment.
