Every mutual fund and ETF charges a fee for managing your money. It is called the expense ratio, or total expense ratio (TER), and it is shown as a percentage per year: for example 0.5% or 1.8%. Because it is small and never appears as a bill, many investors ignore it. Over long periods it can make a large difference to what you end up with. This guide explains what the expense ratio covers, how it is charged, why direct plans cost less, and how to compare it properly.
What the expense ratio covers
A fund has running costs, which are paid out of the money it manages:
- The management fee paid to the asset management company (AMC) for choosing and managing investments.
- Distribution costs, including commission to distributors who sell regular plans.
- Administration: registrar, custodian, audit, legal and marketing costs.
- Some trading costs and taxes, within limits set by SEBI.
SEBI sets maximum expense ratios for each type of fund. The limit falls as a fund grows, and index funds and ETFs have lower limits than actively managed equity funds. The limits have been revised over the years, so check the current figures on SEBI or AMFI. Every fund publishes its actual expense ratio, and changes it within these limits.
How it is charged: daily, from the NAV
You never pay the expense ratio separately. The fund deducts it from its assets every day, in tiny slices: an expense ratio of 1% a year is roughly 1% ÷ 365 of the fund's value each day. The NAV (net asset value per unit) published each evening is already after this deduction.
Your return ≈ return of the fund's holdings − expense ratio
So if a fund's shares gained 12% in a year and its expense ratio was 1.5%, investors received roughly 10.5%. The returns you see in fund fact sheets and on the mutual funds page are already net of expenses.
Direct plans vs regular plans
Every mutual fund scheme has two versions with the same portfolio and the same fund manager:
- Regular plan: bought through a distributor or adviser who receives a commission. The commission is built into a higher expense ratio.
- Direct plan: bought directly from the AMC or through platforms offering direct plans. No commission, so a lower expense ratio.
The gap is often in the range of half a percent to over one percent a year for equity funds. Because the two plans hold identical investments, the direct plan's NAV gradually pulls ahead. Whether a regular plan is worth it depends on the value of the advice and service you receive from your distributor.
A worked example: what 1% costs
Suppose you invest a lump sum of ₹10,00,000 for 20 years, and the fund's holdings earn 12% a year before costs. Compare two expense ratios:
| Expense ratio | Net return a year | Value after 20 years |
|---|---|---|
| 0.5% (for example a direct plan) | 11.5% | about ₹88.2 lakh |
| 1.5% (for example a regular plan) | 10.5% | about ₹73.7 lakh |
The 1% yearly difference costs about ₹14.5 lakh after 20 years, more than the amount originally invested. The reason is compounding: each year's fee also removes the future growth that money would have earned. The same effect applies to a SIP. These are illustrations; real returns vary and are not guaranteed.
Expense ratios of ETFs and index funds
Funds that simply track an index, such as a NIFTY 50 index fund or ETF, do not need expensive research, so their expense ratios are usually much lower than active funds. ETFs are often the cheapest, but you also pay brokerage and the bid-ask spread when buying and selling them on the exchange (see ETF vs mutual fund). For passive funds, also check the tracking error: a cheap fund that tracks its index badly may still lose to a slightly costlier one that tracks it closely.
Context: where fund money goes
Mutual funds are among the domestic institutional investors (DIIs) whose net buying and selling NSE publishes each evening. Here are the latest figures:
Look at the DII column. Behind those large daily numbers are millions of investors paying expense ratios on their holdings. Small percentage differences, multiplied across lakhs of crores of assets, add up to large sums for fund houses, which is why SEBI regulates them closely.
How to use the expense ratio when choosing a fund
- Compare like with like. Compare an equity fund's expense ratio with other funds of the same category, not with a debt fund or an ETF.
- Look at returns after costs. A slightly costlier active fund is only worth it if it consistently beats cheaper alternatives after its fees, which many do not over long periods.
- Check for changes. Funds can change their expense ratio within SEBI limits and must disclose it. Check the latest figure in the fund's documents or on the AMC website.
- Remember other charges. An exit load (a fee for selling within a set period) and taxes are separate from the expense ratio.
Where to find a fund's expense ratio
Fund houses must publish the current expense ratio of every plan of every scheme on their websites, and AMFI collects the figures in one place. The monthly factsheet also shows it, along with the fund's size, portfolio and returns. When an AMC plans to raise a scheme's expense ratio, it has to disclose the change in advance. The mutual funds page lets you look up schemes and compare their figures in one place.
When you read the number, check three things: that it is for the plan you actually hold (direct or regular), that it is the latest figure rather than last year's, and whether the fund is an active or index fund. A 1.2% expense ratio is ordinary for an actively managed direct equity fund but would be very high for a NIFTY 50 index fund.
A quick way to turn the percentage into rupees: multiply your investment by the expense ratio. On ₹5,00,000 at 0.8%, the fund takes about ₹4,000 a year, a little every day. As your investment grows, the rupee amount grows with it, even though the percentage stays the same. On ₹50 lakh, the same 0.8% is ₹40,000 a year.
Common mistakes
- Ignoring it because it looks small. 1% a year is not small over 20 years.
- Choosing only on the lowest expense ratio. Category, risk, tracking and fund quality matter too.
- Thinking the fee is charged once a year. It is taken daily and is already in the NAV.
- Not knowing which plan you hold. Check your account statement: the plan name says "Direct" or "Regular".
