SEBI Total Expense Ratio caps: equity vs debt, the slab structure, and the brokerage carve-in

Today's pre-open is structural, not tactical. Before the bell rings on Dalal Street, every investor running a Systematic Investment Plan or sitting on a corpus of mutual fund units should understand the architecture that quietly governs how much of their gross return the asset manager keeps each year. SEBI's Total Expense Ratio (TER) cap under Regulation 52 of the SEBI (Mutual Funds) Regulations 1996 - last amended on 29 May 2024 - is the single most consequential number for any long-horizon SIP investor. Two schemes tracking the same Nifty 50 universe can deliver materially different terminal wealth simply because one charges 0.20% and the other 1.00%. Over a 20-year horizon, that 80-basis-point gap compounds into roughly a one-fifth difference in corpus.

This morning's note unpacks the slab structure, the equity-versus-debt differential, the brokerage carve-in introduced in June 2023, and what every investor running a SIP or lumpsum projection should check before the next contribution debits the bank account.

Market Snapshot

The TER an Indian mutual fund is permitted to charge is not a single number - it is a tapering staircase that gets cheaper as the scheme gathers assets. SEBI rewrote the framework in September 2018 and the simplified slabs have been in force ever since. The equity schedule below is the canonical reference for every actively managed equity fund domiciled in India.

Debt schemes sit a flat 25 basis points below the equity cap at every step of the staircase. Index funds and exchange-traded funds - including the explosion of Nifty 50, Nifty Next 50, and Sensex trackers that have arrived on Dalal Street since 2020 - face a hard 1.00% ceiling regardless of AUM. Equity Fund of Funds (FoF) schemes may charge up to 2.25%, and a Direct plan must always cost less than the Regular plan of the same scheme by the full distributor commission that the AMC would otherwise pay out.

This is not optional. The slab structure is enshrined in subordinate legislation under the SEBI Act 1992, and any AMC charging beyond the permitted TER is exposed to enforcement action by SEBI's Investment Management Department.

What Moved Yesterday

The TER trajectory has been a slow grind downward, and listed asset management company stocks have repeatedly priced this in. Three regulatory events deserve recall this morning.

First, the September 2018 simplification consolidated what was previously a dual structure - a base TER plus an additional 20-basis-point charge for exit-load credit - into a single tapering schedule. AMCs lost the cushion of that additional 20 bps overnight, and broker-dealer commission economics tightened from the same date. The largest fund houses saw an immediate 8 to 12% compression in revenue yield on their equity book.

Second, SEBI circular SEBI/HO/IMD/IMD-II/DOF3/P/CIR/2023/108 dated 28 June 2023 brought brokerage and transaction costs inside the TER cap. Until then, brokerage on cash-market trades and on futures-and-options transactions was a pass-through borne by the scheme over and above the disclosed TER. The 2023 circular ruled that any brokerage above 12 basis points for cash-market trades and 5 basis points for derivatives must be charged within the TER. The squeeze fell hardest on fund houses that ran high-turnover strategies - small-cap and mid-cap schemes with annual portfolio turnover above 80% effectively lost 10 to 18 basis points of revenue yield from this single circular.

Third, the additional B-30 incentive of 5 basis points - applicable to inflows mobilised from beyond the top 30 cities and long used to push mutual fund penetration into tier-2 and tier-3 India - was withdrawn. Distributors in smaller cities saw commission economics weaken, while AMCs lost a permitted tool to grow geographically. The withdrawal is one structural reason listed AMC valuations re-rated lower through 2023 and early 2024.

These three episodes form the backdrop for any AMC equity-research note today. The direction of travel is clear: TER compression is a multi-year theme, not a one-off shock.

What to Watch Today

Three watch-items deserve a place on the pre-open monitor.

One - TER consultation drift. SEBI has periodically floated discussion papers proposing further reform to the TER framework, including a possible move to a performance-linked TER or unified slabs across equity and debt. Any fresh consultation paper would compress AMC profitability further. Investors should monitor sebi.gov.in's "Reports for Public Comments" tab. A consultation note that proposes capping the equity Direct plan at, say, 75 basis points would cut listed AMC EPS by a high single-digit percentage on a full-year basis.

Two - Direct plan migration. The Direct plan, mandated by SEBI in January 2013, must cost strictly less than the Regular plan by the full trail commission. The gap typically runs 60 to 120 basis points for an equity scheme and 30 to 60 basis points for a debt scheme. Investors still parked in a Regular plan are paying a recurring fee with no service trade-off if they do not actively use a distributor. Switching is treated as a redemption-and-fresh-purchase for capital gains purposes, so the migration needs to be timed thoughtfully around the 12-month long-term capital gains holding period - a 12.5% LTCG rate applies above Rs 1.25 lakh of gains in FY 2025-26 under the post-23-July-2024 Budget regime.

Three - AUM concentration effects. A scheme that crosses Rs 50,000 crore in AUM hits the 1.05% equity floor permanently. The largest five flexi-cap and large-cap schemes in India have already crossed this threshold. New SIP inflows into these schemes face the lowest TER possible under the regulation. A smaller scheme in the same category sitting at, say, Rs 1,000 crore of AUM is permitted to charge close to the 2.25% upper slab - a 120-basis-point gap that compounds enormously over a 20-year horizon. A simple step-up SIP projection that ignores TER differentials will overstate terminal wealth by 15 to 20% over 20 years.

The slab structure also matters for new-fund-offer (NFO) economics. A fresh equity NFO that gathers Rs 300 crore at launch operates entirely in the steepest 2.25% slab, which is why the front-end expense figure in an NFO factsheet often looks high in year one. As the scheme's AUM grows past Rs 500 crore, the weighted-average TER tapers automatically.

The weighted figures above assume the AMC charges the maximum permitted at each slab. The TER actually charged is lower for almost every large scheme and is disclosed monthly on the AMC's own website and on amfiindia.com under "Investor Corner > Total Expense Ratio (TER)."

Practical takeaways for the investor

The intellectual framework for any SIP investor is to treat TER as the certain headwind against an uncertain expected return. Whatever you assume the Nifty 500 will compound at over 20 years, subtract the TER and then subtract another 15 to 25 basis points for tracking error if it is an index fund. A 12% gross compound becomes 11.0% net for a Regular equity scheme charging 1.00%, and roughly 11.8% net for a Direct equivalent charging 0.20%. The 80-basis-point Direct-versus-Regular wedge translates to about 18% additional terminal wealth on a Rs 25,000 monthly SIP run over 25 years - material enough to justify a one-time migration even after accounting for the LTCG impact on the switch.

Index fund and ETF investors enjoy the regulatory 1.00% cap, but the better-managed passive houses charge 5 to 20 basis points for vanilla Nifty 50 and Sensex trackers. Choosing the cheapest tracker within the largest, most liquid scheme is the single most reliable way to maximise long-run wealth in a passive allocation.

For debt scheme investors, the 25-basis-point lower cap across slabs makes the cost differential even more material in proportional terms because gross debt returns are lower to begin with. A debt fund charging 1.20% TER against a benchmark yielding 7.50% loses 16% of its gross return to expenses - a much steeper proportional drag than the equivalent equity scenario. The Direct plan, once again, becomes the default rational choice for the cost-aware investor.

The final practical step is annual housekeeping. Pull the scheme's monthly factsheet on the first weekend of every calendar quarter, note the disclosed TER for both Direct and Regular plans, and verify that nothing has drifted. Any TER increase mid-year must be communicated to unitholders under SEBI's disclosure norms. If a scheme you hold has crept above the slab consistent with its AUM bucket, raise the query with the AMC's investor service desk; it has a regulatory obligation to respond within prescribed timelines under the SEBI (Mutual Funds) Regulations 1996.

FAQ

What is the maximum Total Expense Ratio a SEBI-regulated equity mutual fund can charge?

Under Regulation 52 of the SEBI (Mutual Funds) Regulations 1996, an actively managed equity scheme can charge up to 2.25% on the first Rs 500 crore of AUM, tapering down through the slab structure to 1.05% once the scheme crosses Rs 50,000 crore of AUM. Index funds and ETFs are capped at a hard 1.00% regardless of AUM.

How is the TER for a debt mutual fund different from an equity scheme?

The debt schedule mirrors the equity schedule but every slab is exactly 25 basis points lower. The first Rs 500 crore bucket is capped at 2.00% (versus 2.25% for equity), and the floor for very large debt schemes works out to 0.80%. The 25-basis-point differential reflects the lower research and trading intensity SEBI assumes for fixed-income management.

Are brokerage and transaction costs charged on top of the TER?

Not since 28 June 2023. SEBI circular SEBI/HO/IMD/IMD-II/DOF3/P/CIR/2023/108 brought brokerage and transaction costs inside the TER cap. Any brokerage above 12 basis points for cash-market trades or 5 basis points for derivatives must be absorbed within the disclosed TER, not billed additionally to the scheme. This was a meaningful tightening for high-turnover small-cap and mid-cap strategies.

Why is a Direct plan always cheaper than a Regular plan?

SEBI requires the Direct plan TER to be lower than the Regular plan TER by the full distributor commission the AMC would otherwise pay. The Direct plan structure was introduced with effect from 1 January 2013. The differential typically runs 60 to 120 basis points for an equity scheme and 30 to 60 basis points for a debt scheme - the difference compounds materially over a multi-decade SIP horizon.

What was the B-30 city incentive and is it still in force?

Until its withdrawal, AMCs were permitted to charge an additional 5 basis points on inflows mobilised from beyond the top 30 cities, designed to subsidise distribution costs in smaller markets. SEBI withdrew this incentive as part of the broader TER simplification, removing a structural revenue lever for AMCs while simplifying TER disclosure for investors. The withdrawal was one driver of the AMC valuation re-rating through 2023.

How do I check the current TER charged by a scheme I own?

Every AMC publishes the current scheme TER monthly on its website and aggregates it on amfiindia.com under "Investor Corner > Total Expense Ratio (TER)." The TER is also disclosed in the half-yearly portfolio statement, in the scheme's monthly factsheet, and in the Scheme Information Document. Always compare the Direct and Regular plan TER side by side for the same scheme code.

Does a higher TER guarantee underperformance?

Not in any single year - a skilled active manager can outpace the benchmark even after paying a 1.75% TER. But over 10-year and 20-year windows, the SPIVA India scorecard consistently shows that the median active large-cap fund underperforms its benchmark, and the higher-TER funds underperform more decisively. TER is a certain drag; alpha is uncertain. That asymmetry is the single most important reason fee-aware investors increasingly anchor their core equity allocation to low-cost index funds and reserve active exposure for narrower opportunity sets.
