ETFs versus index funds: choice driven by preference, not cost

An analysis of passive investing says investors must first pick a benchmark index, then choose between an exchange-traded fund and an index fund. The median base expense ratio is 0.15% for index funds against 0.08% for ETFs, but ETFs also attract demat charges, SEBI turnover fees, brokerage and exchange transaction fees including GST. At a price of Rs 61, a Rs 10,000 SIP buys 163 units, leaving Rs 57 unused. Index funds allot fractional units. ETF sale proceeds are credited the next day; index funds take at least two days.

Analysts’ view opinion

AI Economic Analyst

An ETF's base expense ratio (0.08%) is indeed lower than an index fund's (0.15%), but once demat charges, brokerage, SEBI turnover fees, exchange transaction fees and GST are added, much of that saving erodes. The number that matters to an investor is total cost of ownership, not the headline expense ratio. Hence the article's core point: the choice is driven more by preference — especially how fast you need your cash — than by cost.

A gap of 0.07 percentage points may not survive fixed transaction charges on small SIP amounts, though it works better in favour of ETFs at larger ticket sizes.
Because ETFs allot only whole units, a ₹10,000 SIP at ₹61 leaves ₹57 idle — small, but a recurring drag of uninvested money every month.
Index funds allot fractional units, so the entire SIP amount goes to work and the extra transaction charges do not arise.
ETF sale proceeds reach the bank the next day versus at least two days for index funds — an advantage for those who value immediate liquidity, and largely irrelevant for long-horizon goals.
On who gains from the frictions: the ETF route shares revenue with brokers, exchanges and the exchequer (GST, turnover fees), while the index fund route concentrates cost in the fund house's fee.

What to watch — Watch whether rising passive adoption pushes expense ratios and brokerage charges lower still, and how clearly transaction costs are disclosed to retail investors.

The story does not quantify what the additional ETF charges add up to in percentage terms, nor does it compare tracking error or realised returns, so it does not establish which option delivers the better net outcome.

The brief

Context

Passive investing involves tracking a benchmark index rather than picking stocks. An investor must first select the benchmark index and then choose the vehicle on that index — an exchange-traded fund (ETF), which trades on the stock exchange through a trading and demat account, or an index fund, which is bought and redeemed like a mutual fund. This analysis argues that for goal-based investing the choice between the two is driven more by investor preference than by cost, since the ETF's lower expense ratio is offset by transaction charges and the inability to buy fractional units.

Key facts

The median base expense ratio (BER) is 0.15% for an index fund against 0.08% for an ETF, making the ETF cheaper on that measure alone.
ETF investing attracts additional costs: demat charges, SEBI turnover fees, brokerage commission and exchange transaction fees, including GST.
Illustration in the source: at an ETF price of Rs 61, a Rs 10,000 SIP buys 163 units, leaving Rs 57 idle in the trading account.
Index funds can allot fractional units, so the entire SIP amount is invested and the other transaction charges are not incurred.
ETFs can be sold in real time in the market, with money credited to the bank account the next day; index fund sale proceeds take at least two days.
An ETF SIP must be set up through a trading account, and can be set up with market protection so the order is not executed far above the last traded price.
If an ETF SIP is set for a number of units, the amount debited each month varies; if set for an amount, a residual sum remains uninvested.
The recommended benchmark is the large-cap index or the broadest investable index for institutional investors in that market.

Who has a stake

Retail investors doing goal-based investing — Face a trade-off between the ETF's lower expense ratio and its transaction charges, residual uninvested cash and need for a trading account.
Index fund investors — Get fractional units and full deployment of the SIP amount, but pay a higher median BER (0.15%) and wait at least two days for sale proceeds.
ETF investors — Gain real-time selling and next-day credit of proceeds, but bear demat charges, brokerage, SEBI turnover fees and exchange transaction fees with GST.
SEBI — Levies turnover fees on exchange transactions, a component of the total cost of holding ETFs.
Brokers and exchanges — Earn brokerage commission and exchange transaction fees from ETF SIPs and trades.

Why it matters

Passive funds are increasingly used for long-horizon, goal-based savings, and headline expense ratios are the most advertised comparison point. The analysis shows that the visible cost gap of 7 basis points can be neutralised by demat, brokerage, SEBI and exchange charges and by cash left idle because ETFs cannot be bought in fractions. For an ordinary investor, the deciding factors become liquidity preference, convenience and settlement speed rather than cost.

UPSC angle

Prelims pointers

Base expense ratio (median): index fund 0.15%, ETF 0.08%.
ETFs are bought and sold on the exchange through a trading and demat account; index funds are transacted with the fund house.
ETFs cannot be bought in fractional units; index funds can allot fractional units.
Settlement: ETF sale proceeds credited next day; index fund proceeds take at least two days.
ETF transaction costs include SEBI turnover fees, brokerage commission and exchange transaction fees, plus GST.
The NSE 500 Index includes mid-cap and small-cap stocks, exposing investors to momentum crash risk.

Mains framing

The article frames passive fund selection as a two-stage decision: first the benchmark, then the vehicle. On the benchmark, the source cautions that the broadest investable index such as the NSE 500 includes mid-cap and small-cap stocks that can crash regardless of the market's direction — a momentum crash — making it somewhat risky for goal-based investments, so a large-cap index is preferred. On the vehicle, the ETF's median base expense ratio of 0.08% appears cheaper than the index fund's 0.15%, but the comparison is incomplete: an ETF SIP runs through a trading account and attracts demat charges, SEBI turnover fees, brokerage and exchange transaction fees with GST, while the inability to buy fractional units leaves cash idle — Rs 57 on a Rs 10,000 SIP at a price of Rs 61. Index funds deploy the whole instalment and avoid those charges. The offsetting advantage of ETFs is liquidity: real-time selling with next-day credit against at least two days for index funds. The way forward for an investor, per the source, is to treat the decision as one of preference — trading convenience and settlement speed versus full deployment and simplicity — rather than as a pure cost comparison.

Key terms

Exchange-traded fund (ETF): A passive fund whose units trade on the stock exchange in real time, requiring a trading and demat account.
Index fund: A passive mutual fund tracking a benchmark index, which can allot fractional units and avoids exchange transaction charges.
Base expense ratio (BER): The recurring cost of running the fund; median 0.15% for index funds versus 0.08% for ETFs.
Systematic investment plan (SIP): Regular periodic investing; for an ETF it is set up via the trading account, either for a fixed amount or a fixed number of units.
Market protection (on an ETF SIP): An order condition ensuring the purchase is not executed at a price significantly above the last traded price.
Momentum crash: A fall in mid-cap and small-cap stocks that can occur regardless of the overall market's direction.

Practice questions

Compare ETFs and index funds as vehicles for goal-based passive investing, using cost, unit allotment and liquidity as criteria.
"For passive investors, the expense ratio is an incomplete measure of cost." Discuss with reference to ETF transaction charges and fractional unit allotment.
Why may the broadest investable index be less suitable than a large-cap index for goal-based investments? Explain with reference to momentum crash risk.
