Nifty 50 Vs Nifty 500 Vs Nifty Next 50 Index Funds Explained

Last Reviewed and Updated: 17 Aug 2026

Three Different Slices Of The Same Market

All three of these are stock market indices, not investments in themselves. An index fund is simply a mutual fund built to hold whatever stocks a given index holds, in roughly the same proportion, so that the fund's return tracks the index's return before costs.

Nifty 50 covers the 50 largest companies listed on the NSE by free float market capitalisation, the most liquid, most widely held large companies in the country.

As of September 2025, it represented roughly 54% of the NSE's total free float market capitalisation on its own. Nifty Next 50 covers the next tier, companies ranked 51st to 100th, representing roughly 11% of free float market capitalisation as of March 2026.

These are large, established businesses, not mid caps, often described as candidates to graduate into the Nifty 50 itself at a future rebalancing. Nifty 500 is far broader, covering the top 500 companies and roughly 92% of the NSE's free float market capitalisation as of September 2025, spanning large, mid, and small cap companies in one index.

Index	What It Covers	Share Of NSE Free Float Market Cap
Nifty 50	The 50 largest companies by free float market value	Roughly 54%, as of September 2025
Nifty Next 50	Companies ranked 51st to 100th	Roughly 11%, as of March 2026
Nifty 500	The largest 500 companies, spanning large, mid, and small cap	Roughly 92%, as of September 2025

How Much Each One Actually Diversifies You

Owning 500 stocks sounds like a lot more diversification than owning 50, and by count, it is. By weight, the gap is much smaller than it looks, because all three indices are market cap weighted, meaning the largest companies carry the largest share of the fund regardless of how many total names it holds.

In the Nifty 500 itself, the top 10 stocks alone account for roughly 37.5% of the index. Nifty 50, holding only the very largest companies to begin with, is more concentrated at the top than that, simply because it excludes everything below the 50th largest company rather than diluting that concentration across hundreds of smaller names.

A rough way to see this: Nifty 50 and Nifty Next 50 together account for close to 65% of the NSE's entire free float market capitalisation, and Nifty 500 covers about 92% of it. That means Nifty 50 and Nifty Next 50 combined make up somewhere around seven tenths of the Nifty 500 index by weight. A Nifty 500 fund is not a fundamentally different portfolio from a large cap fund with a long tail attached, it is closer to a large cap fund with a long tail attached.

How Each List Actually Changes Over Time

All three indices are reviewed on the same twice yearly cycle, using six months of data ending January 31 and July 31, with changes implemented some weeks later. For Nifty 50 and Nifty Next 50, a company moving up in size can graduate from Next 50 into Nifty 50 itself, or drop out of Next 50 into the broader market, at either of these reviews.

Nifty 500's eligible universe is defined more mechanically, drawing from the top 800 companies ranked by a combination of market capitalisation and trading turnover, with buffer rules that avoid a stock bouncing in and out of the index on a narrow margin.

What The Returns Actually Looked Like Recently

Treat the figures below as a snapshot, not a forecast, for the reason described at the start of this article. As of early July 2026, Nifty Next 50 index funds had delivered a 3 year CAGR of roughly 18.4% to 18.6%, a wide margin ahead of Nifty 50 index funds, whose leading large funds showed a 3 year CAGR of around 8.8% to 8.9% on almost exactly the same date. Nifty 500 index funds, measured slightly earlier in the year, showed 3 year returns in the area of 16%, sitting between the other two, consistent with an index that blends Nifty 50 and Nifty Next 50 with a broader mid and small cap tail.

Index Fund Category	Approximate 3 Year CAGR	As Of
Nifty 50	Roughly 8.8% to 9.2%	Early July 2026
Nifty Next 50	Roughly 18.4% to 18.6%	Early July 2026
Nifty 500	Roughly 16%	Earlier in 2026, likely to have shifted since

A gap this wide, between the calmest of the three indices and the most volatile, is not evidence that one is better. It is evidence that Next 50 is exactly as volatile as its reputation suggests, in whichever direction the market happens to be moving.

Cost And Tracking

Since the Base Expense Ratio framework took effect in April 2026, passive schemes carry a flat cap of 0.90%, well below what actively managed equity funds are permitted to charge. Actual charges on popular index funds tracking these three indices tend to run considerably below even that cap. As one example, a Nifty 500 index fund's Direct Plan carried an expense ratio of 0.17% as of early July 2026.

Every index fund also carries a tracking difference, the gap between what the fund actually returns and what the index itself returns, driven by fees, cash held for redemptions, and the cost of buying and selling the underlying stocks. In one concrete example from July 2026, a large Nifty 50 index fund returned 8.9% over 3 years against a benchmark return of 9.2%, a tracking difference of roughly 0.3 to 0.4 percentage points a year.

A low expense ratio and a low tracking difference are the two things actually worth comparing between funds tracking the same index, since the underlying stocks held will be nearly identical across providers.

Why Holding All Three Does Not Triple Your Diversification

Because Nifty 500 already contains every Nifty 50 and Nifty Next 50 stock inside it, an investor holding a Nifty 50 fund and a Nifty 500 fund together is already substantially overlapping the same large companies, not stacking three genuinely separate portfolios. Adding a Nifty Next 50 fund on top increases exposure to the 51st to 100th largest companies specifically, which is a real and distinct tilt, but adding a Nifty 500 fund alongside both of the others mostly adds a modest slice of mid and small cap exposure at the cost of holding the same largest stocks three times over.

Which One Fits What Kind Of Investor

Nifty 50 is the simplest starting point and the least volatile of the three, a reasonable single core holding for someone who wants broad Indian large cap exposure in one fund and nothing more complicated. Nifty Next 50 is better understood as a satellite added to a Nifty 50 holding than a replacement for it, given the sharper swings in both directions demonstrated by the return figures above, and is generally suggested for investors comfortable holding through at least 5 to 7 years given that volatility.

Nifty 500 suits an investor who wants one fund covering nearly the entire listed market rather than assembling large, mid, and small cap funds separately, with the honest caveat that it behaves far more like a large cap fund than its 500 stock count might suggest.

Note: Trailing return figures for these three indices move more than most investors expect, even over a few months. One widely cited ranking of Nifty 50 index funds put their 3 year CAGR at roughly 13.7% to 13.8% in a snapshot dated late January 2026. A separate snapshot dated July 2, 2026, less than half a year later, put the leading Nifty 50 index fund's 3 year CAGR at 8.9%, against a benchmark return of 9.2%. Both figures were accurate on the day they were published. Neither should be treated as a stable, ongoing fact about the index.
