ETF Long-Term Investing — Why Tracking Error & Expense Ratio Matter

Exchange-Traded Funds are the lowest-cost, most transparent way to gain index exposure. But over 20+ year horizons, the silent drag of expense ratios and tracking errors compound into surprisingly large wealth differentials. A 0.5% annual drag, compounded for 25 years, costs roughly 12% of final corpus.

The Math

Effective net return = Gross index return − Expense ratio − Tracking error. Apply standard SIP FV formula on the net rate. Tracking error captures the deviation between fund NAV and underlying index — caused by cash drag, securities-lending revenue, sampling, and rebalancing slippage.

What to Look For

Expense ratio < 0.20% for large-cap index ETFs.
Tracking error < 0.30% for liquid benchmarks.
Average daily volume > ₹5 crore to ensure tight bid-ask spreads.

Frequently Asked Questions

What is the difference between ETF and mutual fund?

ETFs trade on the exchange like stocks at real-time prices and typically have far lower expense ratios (0.05-0.20%) vs mutual funds (1.0-2.25%). Mutual funds are bought/sold at end-of-day NAV directly with the AMC and support SIP natively.

What is tracking error?

Tracking error is the annualised standard deviation of the difference between an ETF's return and its benchmark index. Lower is better. Indian ETFs typically show 0.10-0.50% tracking error; anything above 1% suggests poor management.

Are ETFs better than index mutual funds in India?

ETFs win on expense ratio. Index mutual funds win on convenience (auto-SIP, no demat needed, no impact cost). For lump-sum investing choose ETFs; for monthly SIP choose index funds — the bid-ask spread on ETFs erodes small monthly buys.

How are ETF returns taxed?

Equity ETFs follow equity taxation: 20% STCG below 12 months, 12.5% LTCG above 12 months (over ₹1.25 lakh annual). Gold and international ETFs follow debt taxation post-2023 — slab rate regardless of holding period.
