Nifty 50 ETF vs Nifty 50 Index Fund

Both a Nifty 50 ETF and a Nifty 50 Index Fund track the same: India's top 50 companies listed on the NSE (National Stock Exchange). Their returns are largely similar in the long term. Their total cost is also similar. So why does one have to choose? Or, why does a different path exist in the first place?

Let’s understand what Nifty 50 ETF and Nifty 50 Index funds are, how they work, and how they compare across key categories.

What Is a Nifty 50 Index Fund?

A Nifty 50 Index Fund is a mutual fund that completely copies the Nifty 50 index. Each stock is invested in the same proportion as it is in the index and your fund's growth path follows that of the index. You do not need a demat account. Like other mutual funds, you can start a Systematic Investment Plan (SIP) directly through any mutual fund platform or your bank.

Whether you invest a lump sum or through an SIP, you invest at the end-of-day NAV. The price is fixed once a day after markets close.

What Is a Nifty 50 ETF?

A Nifty 50 ETF also tracks the same 50 companies, in the same proportion. However, it trades on the stock exchange like a regular share. You buy and sell it through your demat and trading account, just like you would buy a share of Infosys or Reliance.

The price of an ETF changes throughout the trading day just like that of any share. Therefore, if markets are rising at 11am, you can buy at that exact price (and not the closing NAV).

ETF vs Index Fund - Comparison

Investment Costs: Nifty 50 ETFs vs. Nifty 50 Index Funds

One area where ETFs have an edge is cost. Since they trade on stock exchanges, they are generally cheaper to operate than index funds. For example, the ICICI Prudential Nifty 50 ETF has an expense ratio of around 0.02%, while the SBI Nifty 50 ETF charges about 0.04%. In comparison, popular Nifty 50 index funds often charge between 0.2% and 0.35%, depending on the plan.

At first, the difference may not seem to matter as it is in decimals. However, when you invest a substantial sum for a long tenure, even a cost difference of 0.2% per year can translate into a huge amount over 15 - 20 years, thanks to the power of compounding. That said, ETF investors also incur brokerage and transaction charges whenever they buy or sell units. For investors making small monthly investments, these costs can partly offset the ETF's expense-ratio advantage.

The Tracking Error in Nifty 50 ETFs and Nifty 50 Index Funds

Both ETFs and index funds aim to replicate the Nifty 50, but neither can match the index completely. The gap between a fund's return and the index return is known as tracking error.

Tracking error usually happens because funds hold a small cash balance, face transaction costs or need time to adjust their portfolios when stocks enter or leave the index. As a result, two funds tracking the same index can generate slightly different returns over time.

This is why investors should not look only at the expense ratio. A fund with a marginally higher expense ratio but lower tracking error can sometimes outperform a cheaper fund.

Liquidity of Nifty 50 ETFs and Nifty 50 Index Funds

Index funds are bought and sold with the fund house. Transactions happen at the day's closing NAV. Redemption proceeds usually reach investors within one to three business days.

ETFs, on the other hand, trade on stock exchanges throughout the day. This means investors can buy or sell them instantly during market hours.

However, some ETFs may face a liquidity crunch due to low trading volume. Hence, investors choosing the ETF route should generally prefer large and actively traded Nifty 50 ETFs.

FAQs

Is a Nifty 50 ETF better than a Nifty 50 Index Fund?

Not necessarily better, just different. ETFs have a lower expense ratio and offer real-time pricing. Index funds are simpler, need no demat account, and are easier to automate via SIP. For most beginners, the index fund is the better starting point.

Do I need a demat account to invest in a Nifty 50 Index Fund?

No. You can invest in a Nifty 50 Index Fund directly through any mutual fund platform, your bank, or apps like Upstox.

What is the minimum amount to start investing?

For index funds, you can start a SIP with as little as ₹500 per month. For ETFs, you need to buy at least one unit, which varies by ETF price. For example, UTI Nifty 50 ETF trades around ₹160 per unit as of June 2026.

Which Nifty 50 ETF has the lowest expense ratio?

As of May 2026, the ICICI Prudential Nifty 50 ETF has an expense ratio of just 0.02%, making it one of the cheapest options available. SBI Nifty 50 ETF charges 0.04%.

What is tracking error and why does it matter?

Tracking error is the gap between what the Nifty 50 index actually returned and what your fund or ETF delivered. Even funds tracking the same index can give different returns based on how well they replicate it. Always look for a tracking error below 0.10% for Nifty 50 products.

Can I do a SIP in a Nifty 50 ETF?

Yes, most brokers including Upstox now offer automatic SIP features for ETFs. However, it requires slightly more manual setup compared to a regular index fund SIP.

Are returns from a Nifty 50 ETF and Index Fund taxed the same way?

Yes. Both are treated as equity mutual funds for tax purposes. Gains held for less than one year are taxed at 20% (short-term). Gains held for more than one year are taxed at 12.5% on profits above ₹1.25 lakh per financial year (long-term).
