The only number you fully control
A fund's return depends on markets and managers. Its expense ratio depends on a decision you make once, at purchase. That asymmetry is why cost deserves more attention than it gets: the fee is certain, the outperformance it buys is not.
The expense ratio is deducted from the NAV daily — management fees, registrar, custodian, audit, and in regular plans, the distributor's commission. You never receive a bill, which is precisely why the cost feels like zero and compounds like it isn't.
The mechanics of the drag
Say a fund earns 12% gross and charges 1%. Your money compounds at 11%. That one point does not cost "1% of returns" — it costs 1% of your whole balance, every year:
- Year 1 on ₹10 lakh: about ₹10,000.
- Year 15, when the corpus has tripled: about ₹30,000 — that year alone.
- Summed and compounded across the whole journey, the calculator above shows it routinely reaching 10–15% of the final corpus.
The intuition worth keeping: the fee grows with your wealth, whether or not the service improves.
SEBI's caps, and the spread inside them
SEBI caps total expense ratios on a slab by fund size — larger funds must charge less per rupee. Within the caps, the spread is wide: a direct Nifty 50 index fund at 0.15% and a regular sectoral fund at 2.3% differ by a factor of fifteen. Every NYVO fund page prints the exact figure with its as-of date under Key facts.
Three practical rules
- Compare within a category. A 0.9% flexi cap fund against a 0.2% index fund is a strategy choice, not just a cost one; a 0.9% flexi cap against a 1.4% flexi cap is nearly pure cost.
- Direct over regular, always — same fund, lower fee. The difference is a commission, not a service. See the Direct vs Regular calculator.
- Judge fees against the hurdle. A fund charging 1% more must beat its cheaper twin by 1% a year, every year, forever. Few do.
