Expense Ratio Explained: How Fund Charges Silently Eat Your Mutual Fund Returns
The mutual fund's NAV you see on your app is already net of expenses. You never see the deduction — it happens daily, invisibly, before NAV is published. This is why the expense ratio feels theoretical. But compounded over 20 years, a 1% annual expense difference on ₹20,000/month SIP costs you over ₹30 lakh. That is very real money, taken silently.
What Is the Expense Ratio?
The Total Expense Ratio (TER) is the annual cost of running a mutual fund, expressed as a percentage of the fund's average daily assets. It includes:
- Fund management fee (the largest component — fund manager's salary, research team)
- Registrar & transfer agent fees
- Custodian fees
- Audit fees
- Marketing and distribution costs (trail commission in Regular plans)
TER is deducted daily from the fund's NAV before it's published. If a fund earns 12% gross and charges 1.5% TER, investors receive 10.5% net — the difference never appears as a line item anywhere.
SEBI's TER Limits — And Why They Matter
| AUM Slab | Equity Funds Max TER | Debt Funds Max TER |
|---|---|---|
| First ₹500 crore | 2.25% | 2.00% |
| ₹500–₹750 crore | 2.00% | 1.75% |
| ₹750–₹2,000 crore | 1.75% | 1.50% |
| ₹2,000–₹5,000 crore | 1.60% | 1.35% |
| Above ₹50,000 crore | 1.05% | 0.80% |
Larger funds must charge lower TERs — SEBI designed this to pass scale benefits to investors. This is why large-AUM funds from established AMCs often have lower TERs than newer, smaller funds with flashy recent performance.
The 20-Year Compound Cost of 1% Extra TER
| TER | Net Return | Corpus After 20 Years | Lost to Fees |
|---|---|---|---|
| 0.5% (Direct index fund) | 11.5% | ₹1,85,71,000 | — |
| 1.5% (Regular active fund) | 10.5% | ₹1,54,93,000 | ₹30,78,000 |
₹30.78 lakh surrendered to fees over 20 years. This is the cost of not choosing the right plan — and it's the reason index funds + direct plans have become the default recommendation for long-term retail investors.
How to Find a Fund's TER
- SEBI mandates daily TER disclosure on each AMC's website
- Value Research Online → Fund → Expense section shows current TER and historical changes
- Morningstar India also publishes TER history and AMC comparisons
- For index funds, compare TER across AMCs for the same index — Nifty 50 index funds range from 0.10% to 0.50% — there's no justification for the higher-cost versions
FAQ
Does a higher TER mean better fund management?
No. Academic research consistently shows no correlation between higher fees and better risk-adjusted returns in India or globally. The fund manager's skill is what drives returns — and that's captured in CAGR vs benchmark, not in expense ratio. Low-cost index funds often outperform high-expense active funds over 10-year periods.
How is TER different from exit load?
TER is an ongoing annual cost, deducted from NAV daily. Exit load is a one-time charge deducted only when you redeem before a specified period (typically 1 year for equity, 7 days for liquid). Exit loads are typically 1% and are reinvested into the fund — so they don't go to the AMC but instead benefit remaining investors.
Can TER change over time?
Yes. AMCs can change TER within SEBI limits, and they often adjust it as AUM changes. Some AMCs have increased TER on certain schemes — which is why monitoring your fund's TER annually is worthwhile.
