How to Invest in SIP A Beginner's Guide
In summary
An SIP is a method of investing a fixed amount at regular intervals in a mutual fund scheme. It can help you invest systematically without requiring a large upfront amount.
There is no single SIP fund that is best for every investor. The right choice depends on the fund category, your investment horizon, risk capacity, portfolio allocation, costs, and the scheme's investment strategy.
- SIPs can be used across equity, debt, hybrid, and ELSS categories.
- Equity SIPs can suit long-term goals but remain exposed to market fluctuations.
- Review performance across multiple periods rather than relying on one-year returns.
- Compare expense ratios, portfolio composition, risk, and fund-management approach.
- Use the SEBI Riskometer as one input when assessing scheme-level risk.
- Review your SIP periodically when your financial goals or circumstances change.
AMFI reported 1,075.32 lakh outstanding SIP accounts and Rs. 32,297 crore in SIP contributions for August 2026.
What is an SIP mutual fund?
An SIP is a method of investing in a selected mutual fund at regular intervals, usually monthly. The amount is used to purchase units at the applicable NAV on each investment date.
The number of units purchased can therefore vary because the NAV changes. This creates rupee-cost averaging over multiple instalments, although it does not protect you from losses or guarantee positive returns.
If you are new to the concept, you can understand the mechanism by reading - How to invest in SIP.
You can also use the SIP calculator from Bajaj Finance to estimate how different investment amounts and periods could affect a projected corpus. The calculation is illustrative and does not predict actual returns.
Which mutual funds can you consider for an SIP?
Instead of treating a particular scheme as universally best, compare funds according to your objective and risk capacity. The following schemes represent different categories that investors may evaluate.
| Mutual fund scheme | Category | Minimum SIP amount* |
|---|---|---|
| HDFC Mid Cap Opportunities Fund | Mid cap | Rs. 100 |
| Kotak Flexicap Fund | Flexi cap | Rs. 100 |
| SBI Large Cap Fund | Large cap | Rs. 500 |
| Nippon India Large Cap Fund | Large cap | Rs. 100 |
| ICICI Prudential ELSS Tax Saver Fund | ELSS | Rs. 500 |
| Aditya Birla Sun Life Large Cap Fund | Large cap | Rs. 100 |
*Minimum SIP amounts can change and may differ by plan or investment route. Check the latest scheme documents before investing.
The schemes above are examples for comparison, not recommendations. A fund's recent return should not be treated as evidence that it will remain among the top performers.

SEBI's August 2026 data covered 46 flexi cap funds, illustrating that investors have multiple schemes to compare within a single category.
How should you choose the best SIP mutual fund?
The selection process should begin with your financial requirement rather than a return ranking.
Match the fund category with your goal
Large-cap, mid-cap, small-cap, flexi-cap, multi-cap, hybrid, debt, and ELSS funds have different mandates and risk characteristics. A fund designed for long-term equity growth may not be appropriate for a goal due in the near term.
Check your investment horizon
Your investment horizon affects how much market volatility you may be able to tolerate. Equity-oriented funds generally require a longer horizon because their values can fluctuate substantially over shorter periods.
Assess your risk capacity
Risk tolerance describes how comfortable you are with fluctuations, while risk capacity considers whether you can financially withstand them. Both matter when selecting an SIP.
The SEBI Riskometer classifies mutual fund risk as Low, Low to Moderate, Moderate, Moderately High, High, or Very High. It is useful for understanding scheme-level risk, but it does not predict returns.
Compare costs
Review the expense ratio and any applicable exit load. Costs reduce the amount of the portfolio that remains invested, so even seemingly small differences can matter over long periods.
Examine the portfolio
Look beyond returns. Review the fund's top holdings, sector allocation, market-cap exposure, portfolio concentration, and consistency with its stated investment objective.
Evaluate performance across periods
Compare returns over multiple periods and against the appropriate benchmark. A fund that performs strongly during one market phase may behave differently during another.
You can use a mutual fund calculator from Bajaj Finance to understand how different assumptions affect an investment projection, rather than using past returns as a forecast.
What are the benefits of investing through an SIP?
SIPs can provide a structured way to invest, particularly when you receive regular income.
- Regular investing: A fixed contribution can make investing part of your financial routine.
- Rupee-cost averaging: Regular purchases mean you buy more units when NAVs are lower and fewer when they are higher.
- Compounding potential: Returns that remain invested can themselves generate returns over time.
- Flexible contributions: Depending on the scheme and platform, you may be able to modify, pause, or stop future instalments.
- Goal-based planning: You can link the SIP amount and investment period to a defined financial objective.
However, an SIP does not make the underlying mutual fund risk-free.
What mistakes should you avoid when choosing an SIP?
Selecting funds purely on recent performance can result in unsuitable portfolio decisions. Other common mistakes include investing without a defined goal, choosing too many overlapping funds, ignoring costs, and stopping investments solely because markets have declined.
You can learn more about SIP mistakes to avoid, particularly if you are reviewing an existing SIP portfolio.
An SIP also should not be confused with a guaranteed-return product. Market movements can cause the value of your investment to fall, including below the amount invested.
How can you invest in an SIP?
First, identify your goal, time horizon, and risk capacity. Then shortlist suitable categories and compare individual schemes using their investment objectives, portfolios, costs, performance history, and Riskometer.
Complete the required KYC process before investing. You can then select the scheme, investment amount, frequency, and payment mandate according to the available options.
The Bajaj Broking website provides access to 4,000+ mutual fund schemes, allowing investors to compare options across categories. The minimum SIP amount can be Rs. 100, subject to the scheme's terms.
For investors increasing their contribution as their income grows, understanding what a step-up SIP can help when designing a longer-term contribution strategy.
You can also use smart SIP to understand another approach to structuring regular mutual fund investments.
What are the Income Tax implications of SIP investments?
An SIP itself does not have a separate tax rate. Tax treatment depends on the underlying mutual fund, the type of gain, and the holding period of the units.
For qualifying equity-oriented mutual fund units, short-term capital gains covered under Section 111A are generally taxed at 20% for transfers on or after 23 July 2024. Qualifying long-term capital gains under Section 112A are taxed at 12.5% on aggregate gains exceeding Rs. 1.25 lakh in a financial year, subject to applicable conditions.
Each SIP instalment has its own acquisition date and holding period. Therefore, when units are redeemed, different instalments may have different tax treatment.
ELSS funds have an additional tax-saving feature subject to applicable Income Tax provisions, including a three-year statutory lock-in for each investment.
How should you review an SIP portfolio?
An SIP does not need to be changed merely because another fund has recently delivered a higher return. Review your portfolio when your financial goal, investment horizon, risk capacity, or income changes.
You can also review whether two funds have substantial portfolio overlap, whether the fund continues to follow its stated strategy, and whether its risk level remains appropriate.
A periodic review can therefore focus on portfolio suitability, rather than trying to predict which fund will be the next top performer.
Conclusion
The best SIP mutual fund is not necessarily the fund with the highest recent return. Selection should begin with your financial goal, investment horizon, risk capacity, and required asset allocation.
Compare suitable schemes using their category, portfolio, investment strategy, costs, performance across market cycles, and Riskometer. Review your SIP periodically, but avoid making decisions based solely on short-term market movements or return rankings.
The SIP calculator from Bajaj Finance can help you model different contribution amounts and periods as part of your planning.

Frequently Asked Questions
Fund selection and portfolio construction
SIP timing and market conditions
Fund monitoring and changes
How many SIP mutual funds should I have in my portfolio?
There is no fixed number that suits every investor. The number should depend on your goals, portfolio size, fund categories, and the degree of overlap between schemes. Adding several funds with similar portfolios may increase complexity without providing meaningful diversification. Focus on complementary exposures and ensure each fund has a clear role in your overall allocation.
Can I invest in more than one SIP at the same time?
Yes. You can run multiple SIPs if they serve different investment objectives or provide genuinely different portfolio exposures. However, multiple SIPs do not automatically create better diversification. Before adding another scheme, compare its holdings, category, investment style, and risk with your existing funds to determine whether it adds something useful to the portfolio.
Should I increase my SIP when markets fall?
Increasing an SIP during a market decline may be suitable for some investors, but it should not be treated as a guaranteed way to improve returns. The decision should consider your cash flow, financial goals, asset allocation, and risk capacity. Avoid increasing contributions solely because you expect markets to recover quickly, as the timing of recovery cannot be predicted reliably.
Is a monthly SIP better than a quarterly SIP?
Neither frequency is universally better. Monthly SIPs can align well with regular salaries and allow investments to be spread across more dates, while quarterly SIPs may suit certain cash-flow patterns. The more important considerations are the total amount invested, suitability of the fund, investment horizon, and ability to maintain contributions consistently.
When should I stop or replace an SIP?
Consider reviewing an SIP when your financial goal changes, the fund's investment approach changes materially, portfolio concentration becomes unsuitable, or the scheme no longer fits your risk capacity or asset allocation. Poor performance over a short period alone may not justify a change. Compare performance across appropriate periods and understand the reason for underperformance before acting.
