Either is fine — pick UTI by a hair on TER and tracking
UTI Nifty 50 Index Fund has historically run 2-3 bps cheaper TER and 1-2 bps tighter tracking error. That is a roughly ₹500-1,000 per year advantage on a ₹10L corpus — small but free. If you already SIP into HDFC funds, do not switch on this margin alone; the operational hassle outweighs the spread.
Spec sheet, side by side
The metrics that actually differ
AUM bar normalised by a factor of 500 to fit alongside expense ratio and tracking-error percentages. UTI is roughly 45% larger by AUM as of March 2026.
- You are starting fresh and want the lowest direct-plan TER.
- You value the larger AUM and 25-year track record.
- You SIP through MF Utility, Coin, or Groww — both are listed.
- You will hold for 5+ years — the 15-day exit load is irrelevant.
- You consolidate within HDFC AMC for simplicity.
- You want zero exit load with sub-15-day flexibility.
- You want the lower ₹100 SIP minimum.
- You already use the HDFC MF app for other folios.
What 2 basis points actually does
A ₹10,000 monthly SIP for 25 years compounding at 12% nominal yields roughly ₹1.9 Cr. Drop the expense ratio by 2 bps and the corpus rises by approximately ₹50,000-60,000 over the same horizon — small as a ratio of total wealth, but free money for one folio decision. Drop it by 20 bps (e.g. moving from regular to direct plan) and the same SIP gains roughly ₹5-6 lakh.
The bigger lever is regular vs direct, not UTI vs HDFC. For more on this, our mutual funds hub walks through plan selection, and the SIP calculator models compounding gain.
FAQ
Will the returns differ meaningfully between these two funds?
Both track NIFTY 50 TRI. Over a 5-year horizon the gross returns will be virtually indistinguishable — within 5-10 basis points of each other, which is roughly the tracking error band. The deciding factor is the total expense ratio (TER) and the operational efficiency of cash management. UTI's longer index-fund history has translated into marginally tighter tracking, but the difference is rounding-error level for practical investing.
Which one has lower fees?
Both have direct-plan TERs in the 0.18-0.20% band as of FY26. UTI Nifty 50 Index Fund has historically been a few basis points cheaper, but HDFC has matched aggressively as the index-fund category has commoditised. Always check the AMC website for the latest TER before investing — a 5 bps difference compounds to roughly ₹15,000 over 20 years on a ₹10k monthly SIP, real money but not life-changing.
Does AUM matter for index funds?
Larger AUM is mildly preferred for index funds — it improves the fund's ability to absorb large redemption flows without liquidating positions, which keeps tracking error low. UTI Nifty 50 Index Fund manages roughly ₹23,700 crore, HDFC Index Fund - Nifty 50 Plan around ₹16,300 crore. Both are large enough that AUM is not a meaningful differentiator; below ₹500 crore is when AUM starts mattering.
Should I split my SIP across both funds?
No, that introduces complexity without diversification benefit. Both funds hold the same 50 stocks at near-identical weightings. Splitting just doubles your operational overhead at zero risk improvement. Pick one — usually whichever you can SIP from your existing folio platform with the lowest friction — and stick with it.
