Expense ratio — the fee that silently costs you lakhs without a single invoice

Every mutual fund charges a fee every year. Most investors have no idea they are paying it. Here is how it works and why 1% makes a life-changing difference.

Key takeaways

✓

Expense ratio = annual fund management fee as % of your investment

✓

Deducted daily from NAV — you never see a separate bill

✓

1% difference over 20 years costs ₹15–₹20 lakh on ₹10,000/month SIP

✓

Index funds charge 0.1–0.2% vs 1–1.5% for active large-cap funds

✓

Direct plans have lower expense ratios than regular plans — always choose direct

The invisible deduction you never noticed

You check your HDFC Flexi Cap Fund statement. Your investment grew from ₹2 lakh to ₹3.4 lakh over 5 years. Looks like a 70% return. But the fund charged you approximately ₹11,000 in expense ratio over those 5 years — silently, daily, as a tiny fraction removed from each day's NAV before it was calculated. You never wrote a cheque. No notification arrived. But the money is gone.

How it actually gets deducted

The expense ratio is quoted as an annual percentage — say 1.5% per year. But it is deducted daily. If the fund has ₹1,000 crore in assets and charges 1.5% annually: • Daily deduction = 1.5% ÷ 365 = 0.0041% per day • On ₹1,000 crore = ₹41 lakh per day removed from the fund's NAV before it is published This is why the NAV you see is already net of charges. You are never billed separately.

Same fund, same stocks — different expense ratio

₹1070L

Index fund: 0.2% TER → 12.8% net return

₹870L

Active fund: 1.5% TER → 11.5% net return

₹10,000/month SIP for 20 years, same 13% gross return. Difference: ₹2 crore

The TER rule of thumb

For large-cap equity: any active fund charging above 1.2% in direct plan is unlikely to generate enough alpha to justify its cost. Consider an index fund instead. For mid/small-cap: up to 1.5% in direct plan is acceptable if the fund has a strong 5-year track record of beating its benchmark. For debt/liquid: above 0.3% in direct plan is expensive — switch to a cheaper option.

How to check a fund's expense ratio

Use our fund explorer

Search any fund here — we show expense ratio, category average, and a red/green flag if it's above or below average.

Check the AMC factsheet

Every AMC publishes a monthly factsheet. The TER (Total Expense Ratio) is disclosed on page 1 for every scheme.

Compare to category average

An expense ratio means nothing in isolation — 1% for a small-cap fund is competitive; 1% for a large-cap fund is expensive.

Recalculate on switch to direct

If you are in a regular plan, check the direct plan TER. The difference × your corpus = money you are giving to distributors annually.
