The expense ratio may look like a small percentage on paper, but over time, it plays a big role in shaping your actual returns potential from equity funds. Simply put, it is the annual cost you pay for fund management, operations, and distribution, and it is deducted directly from the fund’s assets. This means your potential returns are always shown after expenses, whether markets are rising or falling.
Over the long term, even a difference of 0.3% to 0.5% can compound into a meaningful gap in wealth. Higher expense ratios quietly reduce the power of compounding, especially for investors holding equity funds for 10, 15, or 20 years. This is why cost-efficient funds often perform better when returns are similar.
That said, a lower expense ratio alone does not guarantee superior performance. Some actively managed funds charge more but justify it through consistent stock selection and risk management. The key is balance. Investors should view the expense ratio as an important filter, not the final decision point, and always assess costs alongside performance, strategy, and long-term consistency.
The expense ratio is basically a fee you pay to the AMC for handling your money and investing it wisely. The AMC collects this fee from all the investors, which they use for their day-to-day expenses like legal fees, fund manager salaries, etc.
But how much does an AMC charge you as an expense ratio, and does it affect your long-term returns on equity? In this blog, we will answer this question and more so you can make informed decisions.
When you invest in a mutual fund, the expense ratio is essentially the annual fee you pay for the fund to manage your money. Think of it as the ongoing cost of hiring someone to look after your funds. It’s expressed as a percentage of your total investment and is deducted from your returns each year. So, a higher expense ratio eats into your returns; a lower one leaves more for you.
But how does it work in practice? Every quarter, the fund house calculates all the costs involved in running the fund (like paying fund managers, administrative work, and marketing) and divides that by the total assets under management. That number becomes part of your total cost as an investor.
Management Fees
This is the core cost you pay the fund house for portfolio management. It covers the salary and expertise of the fund managers who decide what stocks or bonds to buy. Good managers are worth paying for, but you want to ensure you’re not overpaying relative to performance.
Maintenance Fees
These are the day-to-day running costs of the mutual fund. Think of office expenses, accounting, and reporting. They’re small individually, but when bundled over years, they add up to a noticeable chunk.
Brokerage
Whenever the fund buys or sells stocks, brokers execute those trades. The broking cost is part of the expense ratio. SEBI has put limits on how much broking can be charged to keep this component in check.
12B-1 Fee
This fee pays for marketing and selling fund units. It’s more common in older funds. In direct plans, this cost is usually absent, so the expense ratio tends to be lower in direct plans.

SEBI recently revamped how mutual fund costs are regulated in India. Below is a simplified look at the Base Expense Ratio (BER) limits for different types of schemes. “Base” means these caps exclude statutory and regulatory levies like GST, STT and stamp duty, which are charged separately.
| Scheme Type | Old Limit (Inclusive Levies) | New BER Limit (From April 2026) |
| Index Funds / ETFs | 1.00% | 0.90% |
| FoFs – liquid/ETFs | 1.00% | 0.90% |
| FoFs – equity >65% | 2.25% | 2.10% |
| Other FoFs | 2.00% | 1.85% |
| Open-ended equity AUM ≤ ₹500 cr | 2.25% | 2.10% |
| Open-ended equity (various AUM slabs) | 1.75%–1.45% | 1.60%–1.35% |
| Open-ended non-equity AUM ≤ ₹500 cr | 2.00% | 1.85% |
| Open-ended non-equity (various AUM slabs) | 1.50%–1.20% | 1.40%–1.00% |
| AUM > ₹50,000 cr – equity | 1.05% | 0.95% |
| AUM > ₹50,000 cr – non-equity | 0.80% | 0.70% |

Over time, even a seemingly small expense ratio difference can dramatically change your returns. Let’s say two equity funds generate similar gross returns, but one charges 2% and the other 1.5% as an expense ratio. After ten or twenty years, that 0.5% gap compounds and can leave you with significantly less wealth, just like a slow leak in a tyre that eventually leaves you stranded.
Especially in equity mutual funds where you’re aiming for long-term growth, every bit of expense matters because the costs get deducted before you see the final return. That’s why many experienced investors lean towards funds with disciplined cost structures and lower ratios.
But remember, the expense ratio isn’t the only thing that matters. A fund with slightly higher costs but consistently better risk-adjusted returns might still be the better choice.

Lower costs are great, but they don’t automatically guarantee better returns. Here’s the catch: a fund with a lower expense ratio might be taking limited risk, tracking a smaller index, or just underperforming its category.
Also, some niche strategies simply require more expertise and higher operational costs. A very low expense ratio fund might compromise on research quality or risk management depth, which can hurt performance during turbulent markets.
So, while low costs are a smart starting filter, they should be balanced with things like consistency, process, and long-term outcomes.
The expense ratio is one of those things you’ll see on every mutual fund factsheet, yet many investors overlook how deeply it affects potential returns over years. It’s more than just a number; it’s the ongoing price of participation in a fund’s strategy and execution.
SEBI’s recent move to reshape the fee framework makes these costs more transparent and easier to compare. But always remember that a smart investment decision considers both costs and the expected value you get in return. After all, value isn’t just about price; it’s about what you get for what you pay.
