Compare Nifty 50 and Nifty 500 over identical dates, using the same type of index series. For an investor-oriented comparison, use the total-return index (TRI) for both: it includes dividends, while a price index does not. State the period, return type and data source so readers can reproduce the result.
What Nifty 50 and Nifty 500 represent
Nifty 50: 50 large, liquid companies
NSE Indices describes Nifty 50 as a diversified 50-stock index, calculated using free-float market-capitalization weighting since 26 June 2009. As of 30 March 2026, it represented 53.73% of the free-float market capitalization of stocks listed on NSE. That is a dated coverage snapshot, not a fixed share of the market. NSE Indices: Nifty 50.

Nifty 500: a wider market-cap range
Nifty 500 represents the top 500 companies by full market capitalization and average daily turnover from the eligible universe. NSE Indices reported that it covered 92.04% of NSE-listed stocks’ free-float market capitalization on 30 March 2026. The selection criteria and the coverage statistic use different market-cap concepts: the former describes eligibility and selection, while the latter measures free-float coverage. NSE Indices: Nifty 500.
The provider’s March 2026 broad-market hierarchy places Nifty 50 and Nifty Next 50 under Nifty 100, and Nifty 100, Nifty Midcap 150 and Nifty Smallcap 250 within the Nifty 500 structure. That helps explain the wider range of companies represented by Nifty 500; breadth alone does not determine which index will return more over a particular period.

Choose price return or total return
A price index tracks changes in share prices and excludes ordinary dividend receipts. NSE Indices separately calculates total-return indices, which include indexed dividends reinvested in the index. So a price-return comparison answers how index prices moved; a TRI comparison is the fairer benchmark for an investor whose holdings receive dividends. The provider advises investors in index stocks to benchmark against the total-return index to assess returns against the index. NSE Indices: Total Return Index.
For a benchmark comparison aimed at investors, compare Nifty 50 TRI with Nifty 500 TRI. Do not pair one index’s TRI with the other index’s price series: that would mix dividend-inclusive and price-only returns. If the question is specifically about price movement, compare the two price indices instead. NSE Indices explains its index terminology in its FAQ.
How to make a like-for-like comparison
- Decide what you are measuring. To compare the benchmarks, compare index returns. To assess a fund, compare its NAV total return after fees with the appropriate benchmark TRI; an index’s performance is not the investor’s realized fund return.
- Select the series. Choose price-return series for a price-movement question, or TRI series for an investor-oriented comparison. Use the same type for both indices.
- Set identical dates. Use the same start and end dates and aligned observations. Match the observation frequency and currency as well. State the precise dates; do not imply that a selected window or frequency is mandated by the index provider.
- Retrieve the index values. Use current factsheets or other data documents offered from the official Nifty 50 and Nifty 500 pages. Record the data source and whether the series is a price index or TRI.
- Calculate each return from its own matching series. For a period, cumulative return = (ending index level ÷ starting index level) − 1. For an annualized return over multiple years, annualized return = (ending level ÷ starting level)(1 ÷ number of years) − 1. Apply the formulas separately to each index and state the exact period. The official methodology gives the price-index return relationship; use the matching TRI levels when calculating total returns. NSE Indices: equity-index methodology.
For longer periods, reporting both cumulative and annualized returns can make the comparison easier to interpret. Label which figure is which; they answer different questions.

Keep market coverage separate from performance
The 53.73% Nifty 50 and 92.04% Nifty 500 figures describe free-float market-cap coverage of NSE-listed stocks on 30 March 2026, not returns. NSE Indices also reported that Nifty 50 constituents accounted for 29.24% of total traded value of all NSE stocks over the six months ending March 2026, while Nifty 500 constituents accounted for 84.07%. Those are trading-value shares, not market-cap coverage or investment performance. Nifty 50; Nifty 500.
Coverage and composition provide context for why the indices may behave differently, but they do not establish which performed better over a chosen period. That requires calculating both returns from the same dates and comparable series.

An index is a rules-based benchmark, not an investable product with fees. An ETF or index fund that tracks Nifty 50 or Nifty 500 can deliver a different investor return because of expenses and tracking difference. When comparing an actual fund with a benchmark, use the fund’s NAV total return after fees and the benchmark TRI over the same dates.
