- Summary
- Expense ratio in mutual funds represents the expenses involved in managing and operating a mutual fund scheme, reflected in its NAV.
- A higher expense ratio can reduce returns over time, as expenses reduce the amount available for compounding.
- TER and BER explain different aspects of mutual fund costs, while regulatory BER limits vary across scheme categories and AUM levels.
- Investors can compare expenses by checking the latest TER, plan type, similar schemes and other applicable costs before investing.
When investing in a mutual fund, the returns you see are not the only thing that matters. The fund also has costs to manage investments and run the scheme. These costs are reflected through the expense ratio. Even a small difference in expenses can affect returns over time, especially for long-term investments. Understanding how the expense ratio in mutual funds works, what it covers, and how it affects returns can help investors assess the actual cost of investing in a mutual fund.
What is the Expense Ratio in Mutual Funds?
The expense ratio is a number that signifies the total expenses in proportion to the size of the fund. It is expressed as a percentage indicating the total fees investors must pay to the asset management company besides investing in the fund.
Asset management companies have dedicated fund managers who pool funds from various investors and manage the investment. These expenses are charges for their professional services. Every mutual fund has a different expense ratio, depending on the company’s policies.
The fees charged depend on the fund’s size, with the two being inversely related. A large-sized fund has a lower expense ratio, while a small-sized fund has a higher expense ratio.
How Does Expense Ratio Affect Your Returns?
The expense ratio is deducted from the fund’s assets, so it affects the returns investors receive. The amount is reflected in the fund’s NAV. A higher expense ratio means a larger share of the fund’s assets is used to meet its expenses.
For instance, a fund that earns a gross return of 10% and has an expense ratio of 1% will give return less than 10% after expenses. The actual difference will depend on how the fund’s value changes and how expenses are charged over time.
The impact becomes more noticeable when an investment is held for many years. The money used to cover expenses is no longer invested and therefore does not benefit from future compounding.
However, a lower expense ratio does not automatically mean higher returns. The fund’s investment approach, market performance and level of risk also influence the returns investors ultimately receive.
Types of Expense Ratios Investors Should Know
Investors may come across different ways of discussing expense ratios while comparing mutual funds:
- Total expense ratio (TER): This represents the total expenses charged to investors under the applicable regulatory framework. From 2026, SEBI’s framework defines TER as the sum of BER, applicable brokerage costs, and regulatory and statutory levies.
- Base expense ratio (BER): BER covers the expenses charged within the base limits prescribed under SEBI’s latest update. These include investment and advisory fees, recurring expenses and permitted distribution-related expenses, excluding applicable statutory levies and transaction costs.
- Direct plan expense ratio: Direct plans do not involve distributor commissions, so their expense ratio is generally lower than the corresponding regular plan.
- Regular plan expense ratio: Regular plans include distribution-related expenses and therefore generally have a higher expense ratio than their direct counterparts. Both plans otherwise belong to the same scheme and have the same portfolio and fund manager.
What Is a Good Expense Ratio for Mutual Funds?
There is no single expense ratio that is considered good for every mutual fund. The cost can vary depending on the type of scheme and how it is managed.
For instance, actively managed funds may have higher expenses because they involve ongoing research, portfolio management and security selection. Passive funds generally have simpler management requirements because they track a market index.
The baseline regulatory limits prescribed by SEBI for different mutual fund categories are structured as follows:
| Fund Category | SEBI Base Expense Ratio (BER) Cap |
| Open-Ended Equity-Oriented Schemes | 2.10% to 0.95%, depending on daily net assets |
| Open-Ended Non-Equity Schemes, Including Debt | 1.85% to 0.70%, depending on daily net assets |
| Index Funds & ETFs | Flat 0.90% |
| Fund of Funds (Liquid/Index/ETF) | Flat 0.90% |
| Fund of Funds | Flat 2.10% |
| Other Fund of Funds | Flat 1.85% |
| Close-Ended Equity-Oriented Schemes | Flat 1.00% |
| Close-Ended Non-Equity Schemes | Flat 0.80% |
Hidden Costs and Common Mistakes Investors Make
The expense ratio is disclosed, but investors can still overlook other charges or misunderstand how different costs affect their investment. Some common mistakes and what to check are:
| Cost or Common Mistake | What It Means | What to Check |
| Ignoring exit load | An exit load may apply when units are redeemed within a specified period. It is separate from the expense ratio. | Check the scheme’s current exit load before redeeming units. |
| Comparing only the expense ratio | A lower expense ratio does not automatically mean that a fund will deliver better returns. | Consider the fund’s strategy, risk and performance along with its costs. |
| Overlooking the plan type | Direct and regular plans have different expense ratios. Regular plans include distribution-related costs, while direct plans do not include distributor commissions. | Check whether the scheme is a direct or regular plan before comparing costs. |
| Using an outdated expense ratio | The expense ratio can change, so an older figure may not reflect the current cost of the scheme. | Check the latest disclosed TER before investing or comparing funds. |
| Ignoring transaction-related costs | Under the current framework, TER includes the applicable base expense ratio, brokerage costs, transaction costs and statutory levies. | Look at the latest expense disclosures instead of focusing only on the headline ratio. |
| Comparing unrelated funds | Expense ratios can vary across fund categories and investment strategies. | Compare funds with similar objectives and investment approaches. |
How to Calculate the Expense Ratio in Mutual Funds?
The expense ratio is calculated by comparing a mutual fund’s annual operating expenses with its average assets under management (AUM). The basic formula is:
Expense Ratio = (Annual Operating Expenses ÷ Average AUM) × 100
For example, suppose a mutual fund has annual operating expenses of ₹50 lakh and an average AUM of ₹100 crore.
Expense Ratio = (₹50 lakh ÷ ₹100 crore) × 100
Since ₹100 crore equals ₹10,000 lakh:
Expense Ratio = (₹50 lakh ÷ ₹10,000 lakh) × 100 = 0.50%
So, the fund’s expense ratio is 0.50%. Investors do not usually pay this amount separately. The expenses are accrued on an ongoing basis and are reflected in the scheme’s NAV. When comparing mutual funds, investors generally look at the expense ratio disclosed by the fund house to understand the cost of each scheme.
Components of the Expense Ratio
A mutual fund’s expense ratio covers the annual expenses involved in managing the scheme and carrying out its day-to-day operations. The ratio is expressed as a percentage of the fund’s average assets under management (AUM). Breaking down these expenses gives investors a clearer view of what they are paying for.
Management fees
Management fees are a key component of the expense ratio and cover the cost of managing the fund’s portfolio and making investment decisions. Fund managers use their expertise to select stocks, bonds and other assets based on the fund’s objectives. High-quality management can justify a slightly higher fee if it translates to better performance over time.
Administrative costs
Administrative costs cover the day-to-day expenses involved in operating a mutual fund. These may include record-keeping, accounting, legal services and custodian charges. Such expenses support the fund’s regular operations, compliance requirements and transaction processing, and form part of the overall expense ratio.
How to Check and Compare Expense Ratios Before Investing
Before investing in a mutual fund, check the latest expense ratio instead of relying on an older figure. Under current rules, mutual funds disclose TER on a daily basis, making it easier to check the cost of a scheme before investing.
When comparing expense ratios, consider the following:
| How To Check | What To Compare |
| Check the latest expense ratio | Look at the most recent TER rather than relying on an older figure, as the expense ratio can change over time. |
| Compare funds in the same category | Compare the TER of schemes with similar investment objectives and strategies so that the cost comparison is meaningful. |
| Compare direct and regular plans | Check the expense ratio of the same scheme under both plans. Direct plans generally have a lower TER because they do not include distributor commissions. |
| Check the difference in percentage points | A small difference in TER can add up over a longer investment period. For instance, a 0.50% TER means ₹50 in annual expenses for every ₹10,000 of assets, before considering changes in the investment value. |
| Compare the TER with similar schemes | A fund with a higher or lower TER should be assessed against other schemes with a similar investment approach rather than compared across unrelated categories. |
Final Thoughts
The expense ratio in mutual funds is one part of the overall cost of investing in a mutual fund. Before investing, it is also useful to check the scheme’s latest factsheet and offer documents for changes in expenses, portfolio details and other terms. Reviewing these periodically can help investors keep track of the costs associated with an existing investment.
