ETF vs Mutual Fund in India: A Practical Comparison for 2026

ETFs and index mutual funds often hold the same underlying portfolio — say, the Nifty 50. But how you buy them, how much you pay, and how taxes apply differ in important ways. Picking the wrong wrapper for your situation can cost 0.5-1.0% per year — material over a multi-decade horizon.

This is a clean comparison framework, with a recommendation for each common use case.

What each is, technically

Mutual Fund (open-ended)

A pooled investment vehicle managed by an AMC. Investors buy and sell units directly with the AMC at the end-of-day NAV. No exchange involvement. Settlement is T+1 to T+3 depending on fund type.

ETF (Exchange-Traded Fund)

A pooled investment vehicle whose units are listed and traded on a stock exchange like a stock. Investors buy from and sell to other market participants, not the AMC. Price moves throughout the trading day. Settlement is T+1.

Both can hold the same index. The wrapper around the holdings is different.

The cost comparison

Cost element	Index Fund (Mutual Fund)	ETF
TER	0.05-0.50%	0.03-0.20%
Brokerage on entry/exit	₹0	₹0-50 per trade (broker-dependent)
STT on sale	0.001% (equity MF)	0.10% (equity ETF)
GST on brokerage	18% on brokerage	18% on brokerage
Bid-ask spread	0% (NAV-based)	0.05-0.30% per trade
Demat AMC	Not needed	Required (₹300-500/year)

For a ₹10,000 monthly SIP over 10 years (₹12 lakh total invested):

Wrapper	TER (assumed)	Total cost over 10 yrs
Direct index fund (0.10% TER)	0.10%	~₹6,000 (TER only)
ETF (0.05% TER, 120 monthly trades, ₹20 brokerage)	0.05%	~₹3,000 TER + ~₹2,400 brokerage + ~₹1,800 spread = ₹7,200

For monthly ₹10,000 SIPs, the index fund is slightly cheaper despite higher TER — because per-transaction costs of ETF compound 120 times.

For a one-time ₹10 lakh investment held 10 years:

Wrapper	Total cost
Index fund (0.10% TER)	₹10,000 over 10 years
ETF (0.05% TER, 1 buy 1 sell, ₹50 each)	₹5,000 TER + ₹100 brokerage + ₹3,000 spread = ₹8,100

ETF wins on lump sums.

When to choose an ETF

• Lump-sum investing of ₹2 lakh+ at a time
• Annual investments rather than monthly
• You already have a demat account
• You want intraday execution (rare for retail; mostly relevant for institutional or advanced investors)
• You're investing in a niche index that has no mutual fund wrapper (e.g. Nifty Next 50 ETF, Bharat Bond ETF)

When to choose an Index Mutual Fund

• Monthly SIPs of ₹500-50,000
• You don't have or don't want a demat account
• You value operational simplicity (no brokerage, no spreads to think about)
• You want automated investing without worrying about market hours
• You're a beginner just starting equity investing

ETF-specific gotchas

1. Liquidity matters more than TER

The cheapest ETF on paper isn't always the best buy. If an ETF has thin daily volume, the bid-ask spread can be 0.50-2% — wiping out years of TER savings.

For Nifty 50 ETFs: stick to the top 3-4 by AUM (Nippon, ICICI, SBI) — they have tight spreads.

For thematic ETFs: check daily volume on NSE. Below ₹1 crore daily turnover, expect wide spreads.

2. iNAV vs market price

During market open and close (and during volatile sessions), an ETF's market price can diverge from its iNAV (indicative NAV based on the underlying basket). Always check iNAV before placing a market order.

For most ETFs in normal market conditions, the market price tracks iNAV within 0.10-0.20%. But during extreme moves (results announcement on a top holding, market-wide circuit), spreads can widen materially. Use limit orders instead of market orders.

3. Discount/premium to NAV

Some less-liquid ETFs trade at a persistent 0.5-1.5% discount or premium to NAV. This is friction every time you transact. Stick to large, liquid ETFs to avoid.

4. Securities Transaction Tax (STT) on sale

ETFs pay 0.10% STT on the sale value. Mutual fund equity redemptions pay only 0.001% STT. On a ₹10 lakh redemption, that's ₹1,000 vs ₹10 — an 100x difference. For frequent traders, this matters.

Tax treatment — same as the underlying

The wrapper doesn't change taxation. Equity ETFs and equity mutual funds (≥65% equity) follow the same rules:

• STCG (held <12 months): 15%
• LTCG (held ≥12 months): 10% above ₹1L per year (post-2024 budget some changes apply)

Debt ETFs and debt mutual funds (post-April 2023): slab rate, no LTCG benefit.

International ETFs (foreign equity): same as international mutual funds — slab rate.

Gold ETFs: same as gold mutual funds — taxed at slab rate post-2023.

Common ETF use cases in India

Use case	Best ETF
Broad large-cap exposure	Nippon Nifty 50 ETF, ICICI Nifty 50 ETF
Mid-cap exposure	Nippon Nifty Midcap 150 ETF
Next 50 (large-mid cusp)	Nippon Nifty Next 50 ETF
Bank exposure	Nippon Nifty Bank ETF
Gold exposure	Nippon Gold ETF (Gold BeES), SBI Gold ETF
US equity	Motilal Oswal Nasdaq 100 ETF, Mirae Asset NYSE FANG+ ETF
Bonds with target maturity	Bharat Bond ETF (April 2030, 2031, 2033)

Common mistakes

• Doing monthly SIPs in ETFs — per-transaction costs eat up the TER advantage. Use index funds.
• Buying thinly-traded thematic ETFs — bid-ask spread is brutal.
• Using market orders on ETFs at market open/close — iNAV diverges; you may pay 0.50-1.0% above fair value.
• Treating ETFs as identical to mutual funds for tax — STT and other costs differ.
• Holding multiple Nifty 50 ETFs — they're functionally identical. Pick the most liquid one.

What to read next

• Nifty 50 index fund deep dive — the index fund alternative.
• Index funds vs active funds in India — the broader passive case.
• Sovereign Gold Bonds vs Gold ETF — gold-specific comparison.
• Mutual fund expense ratio explained — fee analysis.
• SIP calculator — model long-term outcomes.

ETFs and index mutual funds aren't competing products — they're the same idea wrapped differently. Pick the wrapper that matches your contribution pattern (SIP vs lump sum), check liquidity, and stop optimizing beyond that. The wrapper is a footnote; the discipline of staying invested is the headline.
