Returns measure past performance only and should be one input among many — also weigh expense ratio, risk, fund house track record and how the fund fits your goals. Past performance does not guarantee future results.
Plan an investment in index funds
Understanding index funds
An index fund does not try to beat the market — it copies it. The fund manager simply buys the same stocks in the same proportions as an underlying index such as the NIFTY 50, NIFTY 100 or NIFTY Midcap 150, so your return closely mirrors that index minus a small cost. There is no stock-picking, no fund-manager judgement, and therefore no risk of the manager getting it wrong.
That passive approach is precisely why index funds have grown so fast in India. Because there is no research team to pay for, expense ratios are a fraction of what active funds charge — often 0.1–0.2% versus 1.5–2% — and over a 15- or 20-year holding period that cost difference compounds into a very large sum. SEBI data consistently shows a majority of active large-cap funds failing to beat their benchmark over long periods, which makes matching the index a genuinely competitive outcome.
How to choose between index funds
Tracking error — the metric that actually matters
Since every fund tracking the same index holds the same stocks, returns should be nearly identical. What separates a good index fund from a poor one is tracking error: how far the fund drifts from the index it is copying. Lower is better. A fund with 0.1% tracking error is doing its job well; one with 1%+ is losing you return through poor execution, cash drag or delayed rebalancing. Always compare tracking error before returns.
Expense ratio — but check the direct plan
Expense ratio is deducted from your returns daily, so a 0.2% fund beats a 0.5% fund tracking the identical index, all else equal. Always compare the Direct plan (no distributor commission) rather than the Regular plan — the difference is typically 0.5–1% a year, which over 20 years can cost you a substantial share of your final corpus.
Fund size (AUM) and liquidity
A larger fund can track its index more efficiently and absorb inflows and redemptions without being forced to trade at bad prices. Very small index funds sometimes show higher tracking error for exactly this reason. For ETFs specifically, also check on-exchange trading volume — a thinly traded ETF can force you to buy above or sell below its true NAV.
Which index you are actually buying
This is the decision that determines your risk, far more than which fund house you choose. A NIFTY 50 or NIFTY 100 fund gives you large-cap India — steadier, lower long-run growth. A NIFTY Midcap 150 fund is materially more volatile with deeper drawdowns. A NIFTY 500 fund gives you the broadest exposure in one holding. Decide the index first, then pick the cheapest, lowest-tracking-error fund following it.
Ignore short-term return differences between identical funds
If two funds track the same index and one shows a slightly higher 1-year return, that gap is almost always tracking noise, not skill. Chasing it is pointless. Persistent low tracking error and low cost are the only durable advantages an index fund can offer.
Frequently Asked Questions
Which is the best index funds in 2026?
By 3-year CAGR, UTI Nifty 500 Value 50 Index Fund currently tops this list with +27.59%. Rankings are based on past NAV performance and refresh daily — they are not a recommendation.
How are these funds ranked?
Funds are ranked purely by their 3-year CAGR, computed from AMFI NAV history for the Direct-Growth plan. We rank over the longest period the available history supports and extend toward longer 1-, 3- and 5-year windows as more NAV data is collected. Past performance does not guarantee future results.
Are these Direct or Regular plans?
All returns shown are for the Direct-Growth plan, which carries no distributor commission and therefore has a lower expense ratio and typically higher long-term returns than the Regular plan.
What is an index fund?
An index fund is a mutual fund that passively replicates a market index — it buys the same stocks in the same weights as, say, the NIFTY 50 — so its return tracks that index minus a small expense ratio. There is no active stock selection, which keeps costs very low.
Which index fund is best in India?
Because all funds tracking the same index hold the same stocks, "best" comes down to which index you want exposure to, then the lowest expense ratio and lowest tracking error among funds following it. A NIFTY 50 or NIFTY 100 fund is the common starting point for large-cap exposure; a Midcap 150 fund adds growth potential with materially higher volatility. This page ranks funds by past return — use it alongside expense ratio and tracking error, not on its own.
Are index funds better than active mutual funds?
They are cheaper and more predictable: you get the index return minus a small cost, with no risk of manager underperformance. Studies consistently show most active large-cap funds fail to beat their benchmark over long periods after fees. Active funds can still outperform, particularly in mid- and small-cap segments, but you take on manager risk to find out.
What is tracking error in an index fund?
Tracking error measures how much a fund's return deviates from the index it is meant to replicate. Lower is better — it means the fund is copying the index accurately. It is the single most useful quality metric when comparing index funds, since all of them hold the same underlying stocks.
Is a SIP a good way to invest in index funds?
Yes — a monthly SIP in an index fund is one of the most widely recommended long-term strategies in India because it combines low cost, broad diversification and rupee-cost averaging. It suits investors with a horizon of five years or more who want market returns without picking stocks or managers.
Do index funds pay dividends?
Index funds are usually held in the Growth option, where any dividends received from the underlying stocks are reinvested into the fund and reflected in the NAV rather than paid out to you. IDCW variants exist but are generally less tax-efficient for long-term investors.
Returns are computed from AMFI NAV history for the Direct-Growth plan and rank past performance only. This is not investment advice — mutual fund investments are subject to market risks; read all scheme-related documents carefully.
