Expense ratio is the annual fee a mutual fund charges, expressed as a percentage of assets under management. A 1% expense ratio on a ₹10 lakh investment means ₹10,000 per year flows from you to the fund house — silently, automatically, forever.
The compounding cost
On a 20-year investment of ₹1 lakh growing at 12% per year, a 1% expense ratio reduces your final value by roughly 17% compared to a 0% cost fund. That's not a typo — the gap widens the longer you stay invested, because you're losing not just the fee but the returns that fee would have generated.
Direct vs regular plans
Direct plans skip the distributor commission and typically have expense ratios 0.5% to 1.2% lower than regular plans. Over 25 years, that difference can easily amount to lakhs of rupees on even a modest corpus. If you're comfortable picking funds yourself, direct plans are almost always the better choice.
Active vs passive
Index funds and ETFs charge 0.05% to 0.25% because they simply track a benchmark. Active funds charge 0.8% to 2.5% because they try to beat it. The problem? Over 10+ years, most active funds fail to beat their benchmark after fees. If you're paying a premium, make sure the manager is actually delivering alpha.
What to check
Before you invest, compare the expense ratio against the category average. Anything significantly above average needs to be justified by superior returns. Use our fund explorer to see expense ratios alongside returns.
