What is an Index Fund?
An Index Fund is a mutual fund that exactly copies a market index like the Nifty 50 or Sensex. If Reliance has an 8% weight in Nifty 50, the index fund also holds 8% in Reliance. No fund manager judgment — just copy-paste. That's why the cost is very low.
The impact of expense ratio
Active Fund: 1–2% expense ratio per year. Index Fund: 0.1–0.2% expense ratio per year. ₹10 lakh invested for 20 years: Active fund (1.5% expense): ~₹45 lakh. Index fund (0.2% expense): ~₹60 lakh. A difference of ₹15 lakh — just from fees! In compounding, fees matter a lot.
Are index funds really better?
According to the SPIVA India Report, over 10 years, 80%+ of actively managed Large Cap funds underperform the Nifty 50 Index. Paying extra fees for an active fund manager usually doesn't pay off — in most cases, an index fund delivers better results.
