A slow leak in your water tank
Expense ratio is like a tiny hole in your water tank. A small hole (0.5%) barely drips. A bigger hole (1.5%) drains noticeably. Over 20 years, that drip becomes a flood of lost wealth.
What is Expense Ratio
The expense ratio is the annual fee charged by the mutual fund. It covers the AMC's management fees, marketing costs, and distributor commissions (for Regular plans).
How It Works
- Deducted daily from the NAV (not as a separate charge)
- A 1.5% annual expense ratio = ~0.004% deducted from NAV each day
- You never "see" the charge — it's reflected in a slightly lower NAV growth
SEBI's Expense Ratio Caps
SEBI limits maximum expense ratios based on fund type and AUM:
| AUM Slab | Max ER (Equity) |
|---|---|
| First ₹500 Cr | 2.25% |
| Next ₹250 Cr | 2.00% |
| Next ₹1,250 Cr | 1.75% |
| Above ₹50,000 Cr | 1.05% |
The Compounding Effect — ₹10,000/month SIP, 12% gross, 20 years
At 0.3% ER (Index): ₹97.3L. At 1.0% ER (Direct): ₹89.2L. At 1.5% ER (Regular): ₹83.7L. At 2.0% ER (High): ₹78.5L. The difference between 0.3% and 2.0% = ₹18.8 lakh lost to fees.
Rule of Thumb
- Index funds: 0.1-0.3% — excellent
- Active Direct plans: 0.5-1.0% — acceptable
- Regular plans: 1.5-2.0% — consider switching to Direct
- Above 2%: Too expensive — almost never justified
Don't Ignore Expense Ratio
A fund that earns 14% but charges 2% gives you 12% net. An index fund earning 12% but charging 0.2% gives you 11.8% net. The "better" active fund only wins by 0.2% — not worth the risk of underperformance.
