Best Time to Start an SIP: A Beginner's Guide

An SIP can help you invest regularly without having to decide when to make each investment. You can start with an amount that fits your budget and increase it as your financial situation changes.

• Start when your finances allow regular investing.
• Choose an amount you can maintain.
• Align your SIP date with your income.
• You do not need to wait for a market correction.
• Match the fund to your goal and risk level.
• Review your SIP when your financial goals change.

The Bajaj Broking website allows you to start an SIP with a minimum amount of Rs. 100 and offers access to 4,000+ mutual fund schemes. The right fund and investment amount depend on your individual circumstances.

You can start an SIP when you have enough regular income to invest after meeting your essential expenses and other financial commitments. You do not need to wait for a particular market level or calendar date.

Starting earlier can give your money more time to remain invested. Over a longer period, returns earned on an investment can also generate further returns. This is commonly referred to as compounding.

However, starting early does not guarantee a profit. Mutual fund returns depend on the performance of the underlying scheme and market conditions.

Starting when your cash flow is stable

Before starting an SIP, look at your monthly income and regular expenses. The amount left after essential spending, debt payments, and other important commitments can help you decide how much you can invest.

Your SIP should be sustainable. Choosing an amount that is too high can make it difficult to continue investing when your expenses increase.

Giving your investment enough time

Your investment horizon matters because different financial goals may need different time frames.

For example, money required in the near term may need a different approach from money being invested for a long-term retirement goal. Consider when you will need the money before selecting a mutual fund.

Starting an SIP involves more than choosing an amount and a date. You should first understand your financial position, goal, investment horizon, and ability to take market risk.

Checking your monthly cash flow

List your regular income and essential expenses. Then identify how much you can invest without affecting your day-to-day financial needs.

For example, if your monthly income is Rs. 50,000 and your essential expenses and other commitments use most of it, starting with a smaller SIP may be more suitable than choosing an amount that leaves little room for unexpected expenses.

Setting a clear financial goal

A goal gives your SIP a purpose. You may be investing for retirement, a child's higher education, a home, or another long-term financial requirement.

Your goal can also help you decide how long you need to stay invested and what level of market risk you may be able to consider.

Considering your investment horizon

Your investment horizon is the length of time you expect to remain invested.

A longer horizon may allow you to stay invested through different market cycles. A shorter horizon gives you less time to recover if the value of your investment falls.

There is no universally correct SIP date. The practical choice is a date that gives you enough money in your bank account after your income is credited.

For example, if your salary is credited on the first day of every month, you could choose an SIP date a few days later. This can help ensure that the required amount is available when the instalment is due.

Aligning the date with your income

Choose an SIP date based on your actual cash flow rather than assuming that one calendar date is best for everyone.

If your income arrives at different times during the month, select a date that fits your regular cash flow pattern.

Avoiding unnecessary delays

You do not need to wait until the end of the month to invest if you already have the money available.

The more important consideration is whether you can maintain the chosen SIP amount regularly.

You do not need to wait for a market correction to start an SIP. Predicting the right market entry point is difficult, and waiting can also delay your investment.

With an SIP, you invest a fixed amount at regular intervals. When prices are lower, the same amount can buy more units. When prices are higher, it buys fewer units. This mechanism is known as rupee-cost averaging.

You can learn more about how this works through mutual fund units.

Understanding rupee-cost averaging

Rupee-cost averaging does not remove market risk or guarantee a profit. It is simply a result of investing a fixed amount at regular intervals across different market prices.

This means you do not have to make a new market-timing decision for every SIP instalment.

Understanding market risk

Mutual fund values can rise or fall with market conditions. An SIP does not protect you from losses if the underlying mutual fund performs poorly.

You should therefore consider the scheme's investment objective, risk level, portfolio, and Riskometer before investing.

The SEBI Riskometer classifies mutual fund schemes as Low, Low to Moderate, Moderate, Moderately High, High, or Very High risk.

Yes. A bonus, inheritance, or other windfall can provide additional money that you may choose to invest. However, you should first consider whether you need the money for immediate expenses, debt repayment, or an emergency fund.

You can also use a part of a windfall to begin or increase an SIP rather than committing the entire amount to regular investments.

If you receive a windfall, you can learn more about windfall and how it may fit into your broader financial plan.

Using a bonus thoughtfully

Suppose you receive a yearly bonus of Rs. 60,000. You could consider your existing financial commitments first and then decide whether some of the money should be invested.

The decision should be based on your financial goal and circumstances rather than simply investing because the money has become available.

Separating lumpsum investing from an SIP

A lumpsum investment means investing a larger amount at one time. An SIP involves investing a fixed amount at regular intervals.

If you receive a large amount, you can consider these as separate investment decisions. Your choice should depend on your goal, time horizon, risk tolerance, and financial needs.

You can use the lumpsum calculator from Bajaj Finance to understand how a lumpsum investment may grow based on the assumptions you enter.

Your financial goal helps determine how long you may need to stay invested and how much you may need to invest.

For example, someone saving for retirement may have a longer investment horizon than someone saving for a goal due in three years. The choice of mutual fund should reflect these differences.

Once you define your goal, you can find a mutual fund that suits you.

Matching the goal with the time horizon

Start by identifying when you expect to need the money. Then consider the type of mutual fund and level of market risk that may be appropriate for that period.

Do not select a fund only because it has delivered strong returns in the past. Past performance does not guarantee future returns.

Considering your risk level

Your ability and willingness to handle fluctuations in the value of your investment are important when selecting a mutual fund.

The Riskometer can help you understand the risk level assigned to a mutual fund scheme. You should also read the scheme-related documents before investing.

Consider Rahul, a 30-year-old salaried employee earning Rs. 50,000 a month. After accounting for his essential expenses and other commitments, he decides that Rs. 5,000 a month is an amount he can invest regularly.

Rahul chooses an SIP because he wants to invest regularly towards a long-term financial goal. He selects a SIP date shortly after his salary is credited so that the required amount is available in his bank account.

The example is illustrative. It does not represent a guaranteed return or suggest that Rs. 5,000 is the right SIP amount for every investor.

What Rahul should review before investing

Rahul should consider:

• His monthly income and expenses.
• His investment goal and target date.
• His investment horizon.
• His ability to handle market fluctuations.
• The mutual fund's investment objective and risk level.
• Whether the SIP amount remains affordable if his expenses increase.

If his financial circumstances change, he can review whether the SIP amount still fits his budget.

Choosing an SIP amount is only one part of the decision. You also need to select a mutual fund that fits your financial goal, investment horizon, and risk level.

The Bajaj Broking website provides access to 4,000+ mutual fund schemes across categories, including equity, debt, hybrid, ELSS, and thematic funds.

Looking at the fund category

Different mutual fund categories invest in different types of assets and can have different levels of risk.

Equity funds generally invest mainly in shares, while debt funds invest in debt and money-market instruments. Hybrid funds combine different asset classes.

Understanding the category can help you narrow your choices before comparing individual schemes.

Checking the Riskometer

The Riskometer gives you an indication of a scheme's risk level. The available categories are Low, Low to Moderate, Moderate, Moderately High, High, and Very High.

Use this information alongside the scheme's objective, portfolio, investment horizon, and your own risk tolerance.

There is no single SIP amount that is suitable for everyone. Your amount should fit your income, expenses, financial goals, existing investments, and other commitments.

The Bajaj Broking website allows you to start an SIP with a minimum amount of Rs. 100.

Instead of choosing an amount based on a general percentage or age-based formula, start with an amount you can realistically maintain.

Starting with an affordable amount

For a beginner, a smaller SIP that can be maintained consistently may be more practical than choosing a larger amount that puts pressure on the monthly budget.

You can review the amount later if your income increases or your financial priorities change.

Estimating your potential investment value

A mutual fund calculator can help you estimate the potential value of your investment based on the amount, period, and assumed rate of return you enter.

These calculations are illustrations. Actual mutual fund returns can be different because market returns cannot be predicted.

An SIP can be a way for beginners to invest regularly in mutual funds. However, an SIP itself does not determine whether a particular mutual fund is suitable for you.

Before investing, understand the scheme's objective, risk level, investment strategy, and the time period for which you may need to stay invested.

You should also complete the required KYC process before investing in mutual funds.

Understanding what an SIP does

An SIP is a method of investing. It does not represent a particular mutual fund category.

You still need to choose the mutual fund scheme in which your SIP instalments will be invested.

Understanding what an SIP does not do

An SIP does not guarantee returns, remove market risk, or ensure that your investment will make a profit.

The value of your investment can fall if the underlying mutual fund's NAV falls.

Yes. An SIP can make a loss because the underlying mutual fund is exposed to market movements.

For example, if you invest Rs. 5,000 through an SIP and the value of the units later falls because of market conditions, your investment value can be lower than the amount you have invested.

Regular investing does not eliminate this risk. It only changes how and when you invest.

Understanding NAV movements

NAV, or Net Asset Value, represents the per-unit value of a mutual fund scheme.

When the NAV changes, the value of your mutual fund units also changes. Your SIP instalment buys units based on the applicable NAV for that transaction.

An SIP and a fixed deposit serve different purposes, so they should not be treated as interchangeable products.

An SIP invests in a mutual fund and is subject to market risk. A fixed deposit generally offers a predetermined interest rate for a specified period, subject to the terms of the deposit.

Your choice should depend on your financial goal, time horizon, need for certainty, and ability to accept investment risk.

Understanding the difference in risk

A mutual fund investment can gain or lose value as markets change. A fixed deposit does not have the same market-linked value fluctuations, although other terms and risks may apply.

The two products should therefore be compared based on their features and your financial requirements rather than expected returns alone.

SIP investing continues to represent a significant part of mutual fund investing in India. According to the Association of Mutual Funds in India (AMFI), SIP contributions during August 2026 were Rs. 32,297 crore. AMFI also reported more than 1,001 lakh contributing SIP accounts for that month.

This data shows the scale of SIP investing, but it does not indicate that an SIP will produce a particular return for an individual investor.
