The Best Index Funds in India for 2026 (And How to Pick One)
Compare top index funds in India for 2026 by expense ratio, tracking error, and AUM to find the best fit for your portfolio.
You’ve probably already plugged your numbers into the calculator above and seen something that made you sit up a little straighter. Good. Now let’s talk about where that money should actually go.
Index funds have gone from a niche idea to mainstream in India over the last five years — and for most salaried investors, they’re genuinely the smartest starting point. Not because they’re exciting, but because they’re hard to mess up.
What You’re Actually Buying
When you invest in an index fund, you’re buying a tiny slice of every company in a specific index — say, the Nifty 50, which tracks India’s 50 largest publicly listed companies. The fund doesn’t have a manager trying to pick winners. It just mirrors the index, automatically.
That simplicity is the whole point. It keeps costs low, removes human error, and historically, it beats most actively managed funds over a 10–15 year horizon in India.
The One Number That Matters Most: Expense Ratio
Before anything else, check the expense ratio. This is the annual fee the fund house charges to manage your money — expressed as a percentage of your total investment. It gets deducted automatically, so you never “see” it leave your account, which is exactly why people ignore it.
But here’s why you shouldn’t. Say you’re earning ₹70,000 a month in Bangalore and investing ₹14,000 monthly in a Nifty 50 index fund. Over 20 years, assuming 12% CAGR (that’s Compound Annual Growth Rate — the average yearly return if growth compounded on itself), your corpus would be roughly ₹1.4 crore.
Now run the same numbers with a fund charging 0.10% expense ratio versus one charging 0.50%. That 0.40% difference silently costs you around ₹8–10 lakh over two decades. Same market. Same discipline. Just a worse fund.
| Fund | Expense Ratio | 20-Year Corpus (₹14,000/month SIP, 12% CAGR) |
|---|---|---|
| UTI Nifty 50 Direct | 0.18% | ~₹1.38 crore |
| HDFC Index Fund Nifty 50 Direct | 0.20% | ~₹1.37 crore |
| SBI Nifty Index Fund Direct | 0.20% | ~₹1.37 crore |
| A higher-cost active fund | 1.50% | ~₹1.18 crore |
The difference between the top three is negligible. The difference between any of them and a 1.5% expense ratio fund is significant enough to matter to your actual retirement.
Which Index Should You Track?
This is where people overthink it. For someone building their first or primary equity investment, Nifty 50 is the answer. It covers large-cap companies across sectors — Reliance, TCS, HDFC Bank, Infosys — and it’s the most liquid, most researched, and most cost-efficient index to track in India.
Once you’ve got a foundation there, Nifty Next 50 is a worthwhile addition. It covers the next tier of large companies — businesses that aren’t quite Nifty 50 yet but often graduate into it. Historically, it’s been more volatile but has delivered slightly higher returns over long periods.
If you want to capture the whole market in one go, the Nifty 500 or total market index funds do that. UTI and Motilal Oswal both offer these at reasonable expense ratios.
Avoid getting pulled into thematic index funds — tech indices, ESG indices, consumption indices — until the basics are sorted. They’re fine products, but they’re a second-layer decision, not a foundation.
The Funds Worth Your Attention in 2026
Three options that consistently score well on expense ratio, tracking error (how closely the fund actually mirrors its index — a smaller gap is better), and fund house reliability:
- UTI Nifty 50 Index Fund – Direct Plan: Long track record, tight tracking, expense ratio around 0.18%. A solid default choice.
- HDFC Index Fund Nifty 50 – Direct Plan: Backed by one of India’s largest AMCs, expense ratio around 0.20%, and widely available on Zerodha, Groww, and Kuvera.
- Motilal Oswal Nifty 500 Index Fund – Direct Plan: If you want broader market exposure beyond just the top 50, this is the cleanest option. Expense ratio around 0.20%.
Always choose the Direct Plan, not the Regular Plan. Regular plans include a distributor commission baked in — typically 0.5–1% extra per year — which adds up to a significant drag over time. On Zerodha Coin, Groww, or Kuvera, you automatically get the direct plan.
What to Actually Do Next
If you’ve done the SIP calculator exercise and have a monthly number in mind, set up a SIP — Systematic Investment Plan, meaning a fixed monthly auto-debit into the fund — directly through Kuvera or Groww. It takes about 15 minutes. Pick the UTI or HDFC Nifty 50 Direct plan to start, set it to auto-debit on your salary date, and leave it alone.
You can use our SIP calculator at /tools/sip-calculator/ to model what happens when you increase your SIP by 10% each year as your salary grows — it changes the final number more than almost any fund-selection decision will.
The best index fund is the one you actually stay invested in for 15 years. Pick one of the three above, start this week, and revisit the question in five years.
Frequently Asked Questions
Which is the best index fund for beginners in India?
UTI Nifty 50 Index Fund – Direct Plan is the most practical starting point. It has a low expense ratio of around 0.18%, a strong track record, and is available on all major platforms including Groww, Kuvera, and Zerodha Coin.
What is a good expense ratio for an index fund in India?
Anything at or below 0.25% is competitive for Nifty 50 index funds in India. If a fund is charging above 0.50% and calling itself an index fund, there’s no good reason to pick it over cheaper alternatives tracking the same index.
Is Nifty 50 index fund safe?
It’s equity — so the value goes up and down with the market, and short-term dips of 20–30% are normal and have happened multiple times historically. Over 10+ year periods, the Nifty 50 has never delivered a negative return. The risk is real; the time horizon is what manages it.
Should I invest in Nifty 50 or Nifty Next 50?
Start with Nifty 50. Once you have at least ₹2–3 lakh accumulated there, adding a Nifty Next 50 fund makes sense for a bit more growth potential at the cost of higher short-term volatility. Don’t split a small corpus across multiple funds — concentration early, diversification later.
Can I invest in index funds through SIP on Zerodha?
Yes — through Zerodha Coin, you can invest in direct plan mutual funds including all major index funds via SIP. There’s no transaction fee on mutual fund purchases through Coin, and you get the full direct plan benefit without a distributor commission eating into your returns.
