A 1% fee does not cost you 1% — it costs you a quarter of your money
Fees compound exactly the way returns do. Over thirty years, a one percentage point difference removes a startling share of the final corpus.
An expense ratio is quoted as a small annual number, which is precisely why it gets underestimated. It is not deducted once. It comes off every year, from a balance that would otherwise have kept compounding.
What one percentage point does
₹10,000 a month for 30 years, gross return 12%:
| Expense ratio | Net return | Final corpus |
|---|---|---|
| 0.2% | 11.8% | ₹3.32 crore |
| 1.0% | 11.0% | ₹2.83 crore |
| 1.8% | 10.2% | ₹2.41 crore |
The gap between the cheapest and the dearest is roughly ₹91 lakh — on identical contributions, from identical gross performance. That is about 27% of the final corpus, paid out in fees you never saw as a transaction.
Where else the drag hides
- Regular versus direct plans. Distributor commission is baked into the regular plan's expense ratio, typically 0.5 to 1.0 percentage points. Same fund, same manager, same portfolio, different outcome.
- Exit loads. Usually around 1% if you redeem within a year. Harmless if you never do, expensive if you rebalance often.
- Churn. Every redemption is a taxable event. Tax paid early is money permanently removed from the compounding base.
- Cash drag. A fund holding 5% in cash for liquidity earns deposit rates on that slice, not equity returns.
The one place a higher fee can be worth it
If a fund genuinely delivers more than its extra cost, net of that cost, it wins. The difficulty is that you can only identify this in hindsight, and the persistence of outperformance is weak. The cost, by contrast, is known in advance and certain.
Certain cost against uncertain benefit is the whole argument, and it is why low-cost options have won so much of the flow over the last decade.
