Small-cap index funds have had a rough patch. After the sharp run-up in small-cap valuations through 2024 and early 2025, the segment corrected hard, and a lot of the 1-year return numbers you will see below look modest compared to what small-cap investors got used to a couple of years back. That is not a reason to avoid the category. It is a reminder of what small caps actually are and why you should consider them.
A small cap index fund simply tracks an index like the Nifty Smallcap 50 or Nifty Smallcap 250. It is the same as buying the stocks in the same proportion as the index, but without a fund manager trying to pick winners. You get the sector, the returns, and the risk of the small-cap segment as a whole, at a much lower cost than an actively managed small-cap fund.
Below is a rundown of the ten best small-cap index funds in India you can look at right now, along with what actually separates one from another.

Overview of Best Small-Cap Index Funds
1. Nippon India Nifty Smallcap 250 Index Fund
Nippon India has been a familiar name among mutual fund investors for years. This fund extends that presence into passive small-cap investing. It follows the broader index. This makes it suitable for those who prefer diversification instead of relying on a smaller basket of stocks.
2. Motilal Oswal Nifty Smallcap 250 Index Fund
Investors who prefer broad market exposure over a concentrated portfolio may find this a better fit. Since the fund simply follows the index, there is no active stock picking involved. This means that the cost of the fund is very low, and it allows the investors to participate in the overall growth of India’s small-cap segment.
3. ICICI Prudential Nifty Smallcap 250 Index Fund
This is not a new name in the list. It rounds out the list with another passive option tracking the broader small-cap index. Since the underlying benchmark is identical to several peers, investors are generally better off comparing the crucial factors. These include the expense ratio, tracking error, AUM, and ease of investing. ALl these will help you in investing.
4. Axis Nifty Smallcap 50 Index Fund
One thing that stands out here is the focused portfolio. Since it tracks the Nifty Smallcap 50, you’re getting exposure to just 50 companies. This is quite broader as compared to the simple small-cap universe. That concentration can work in your favour during a strong rally, although it also means the fund is likely to witness sharper swings when sentiment turns negative.
5. Aditya Birla Sun Life Nifty Smallcap 50 Index Fund
There isn’t a major strategy difference between this and other funds tracking the same index. The returns will largely depend on how closely the fund mirrors the benchmark and how efficiently it keeps costs under control. If your goal is simply to own the Nifty Smallcap 50 through a passive route, this is another option to compare.
6. Kotak Nifty Smallcap 50 Index Fund
This is the fund that offers the same benchmark exposure. This is where as the investor you would need to pay more attention to the key factors. These include tracking error, expense ratio, and overall fund efficiency rather than expecting a different investment strategy. Over the long run, even small differences in these metrics can make an impact.
7. Edelweiss Nifty Smallcap 250 Index Fund
This is where the approach changes. Instead of limiting itself to 50 stocks, the fund spreads investments across the Nifty Smallcap 250. This allows you to have better exposure to the market and have better growth prospects. The broader diversification doesn’t eliminate risk, but it does reduce the dependence on a handful of companies driving returns.
8. Groww Nifty Smallcap 250 Index Fund
Being a relatively newer offering, this fund doesn’t have the long operating history of some peers. Even so, it gives investors access to the same 250-stock index, making it worth comparing on parameters such as tracking efficiency, costs, and fund size rather than past returns alone.
9. Kotak Nifty Smallcap 250 Index Fund
For investors comparing Kotak’s two small-cap index funds, the key difference comes down to diversification. The 250-stock version spreads risk much more widely, while the 50-stock variant offers a more concentrated bet on the segment.
10. Bandhan Nifty Smallcap 250 Index Fund
Bandhan keeps things uncomplicated with a straightforward index strategy. Rather than trying to outperform the market, the objective is simply to replicate the returns. This is one of the reasons why many investors go ahead with the fund, as it makes it easier to track and trace the fund in the long run.

| Diversification | Lower | Higher |
| Concentration Risk | High | Lower |
| Volatility | Higher | Moderate to High |

| Best For | Investors comfortable with larger swings | Investors looking for a steadier passive investment |
Which Should You Pick?
- Choose Nifty Smallcap 50 if you are comfortable with higher risk. You will get a comparatively conservative portfolio but this will help you in the growth as well. The management will be easier.
- Choose Nifty Smallcap 250 if you prefer broader diversification. If you want to reduce concentration risk while still participating in the long-term growth potential of small-cap stocks.
If you consider this in a very general sense, then Nifty Smallcap 250 is more preferred by the investors as this gives a fair enough and general idea of the market.
What to Actually Check Before Investing
The returns table gets all the attention, but a few other numbers matter just as much, sometimes more, over a long SIP.
- Expense ratio: The difference between 0.14% and 1.07% doesn’t sound like much year to year, but compounded over a decade or two it can shave off a meaningful chunk of your final corpus.
- Exit load and its time window: Some of these funds charge nothing if you exit, others penalise you for leaving within the first week or two weeks. Know this before you invest, not after you try to redeem.
- Fund size: A larger fund tends to track its index more tightly and handle redemptions more smoothly. Very small funds aren’t necessarily bad, but they’re worth a second look.
- Tracking error: How closely does the fund actually follow its underlying index? This isn’t in the table above, but it’s published in every fund’s factsheet and is worth checking before you commit.
Should You Even Be Investing in Small-Cap Index Funds Right Now
Small caps go through long stretches where they simply do nothing, followed by sharp bursts of outperformance that make up for the wait, and then just as sharp a fall. Some of the things to consider while investing are as follows:
- Suitable only if your investment horizon is 5 to 7 years or longer.
- Be prepared for high volatility and sharp market corrections.
- Avoid investing if you need the money in the near term.
- Invest through a SIP to average your purchase cost across market cycles.
- Stay invested during market ups and downs instead of reacting to short-term movements.
- Use a platform like Pocketful to track your SIPs and overall portfolio in one place.
