Index vs Active Fund: Which Grows Your ₹5K SIP More?

Choosing between an index fund and an active large-cap fund is one of the most common investing dilemmas. One is cheap and predictable, the other aims to beat the market — but rarely does consistently. Here is what you need to know before investing.

Here's what happened: Index funds like UTI Nifty 50 simply mirror the Nifty 50 basket, keeping costs ultra-low — expense ratios often below 0.20% per year.. Actively managed large-cap funds employ fund managers who pick stocks trying to beat the Nifty 50, but charge higher fees (0.9–1.5% expense ratio).. SEBI data shows over 70% of active large-cap funds failed to beat their benchmark index consistently over a rolling 5-year period..

What you should do: Compare expense ratios on MF Central or Value Research — even a 1% fee difference erodes ₹3–4 lakh on a ₹10K/month SIP over 15 years.. Check your existing large-cap fund's 5-year and 10-year rolling returns against the Nifty 50 TRI benchmark before adding more money.. If you are a first-time investor or have less than ₹5,000/month to invest, start with a Nifty 50 index fund — lower cost, lower stress..

Always compare active funds against the Total Returns Index (TRI), not the plain Nifty 50 Price Index — TRI includes dividends and sets a much tougher benchmark most active funds quietly avoid mentioning.
