The TER slab that quietly caps your equity fund fee: SEBI's 2.25% to 1.05% sliding scale and what it costs long-term

Most investors compare equity funds on their headline returns and never look at the one number that is deducted from those returns every single day: the Total Expense Ratio (TER). Since 1 April 2019, SEBI has capped that number on a sliding scale that starts at 2.25% and falls to a floor of 1.05% as a scheme grows, under circular SEBI/HO/IMD/DF2/CIR/P/2018/137 dated 22 October 2018. The cap protects you at the top, but the gap that survives inside it — chiefly the 1.0 percentage-point difference between a regular plan and a direct plan of the same fund — is what quietly decides how much of a 15-to-20-year corpus you actually keep.

This piece sets the regular plan against the direct plan of the identical scheme, because that is where SEBI's TER rules bite hardest for an ordinary investor. Both plans hold the same securities and share the same fund manager; the only structural difference is that a regular plan embeds a distribution commission and a direct plan does not. On a Rs 10 lakh holding compounding for two decades, that single line item is worth close to Rs 14 lakh, as the arithmetic below shows.

The framing throughout is "regular plan vs direct plan for long-term equity wealth", because the TER slab is the mechanism and the plan choice is the lever you actually control. You cannot change the slab a fund sits in, but you can choose which side of the commission line you invest from.

How SEBI's TER slabs actually work

SEBI regulates the maximum TER an open-ended equity scheme may charge under Regulation 52 of the SEBI (Mutual Funds) Regulations, 1996, as amended by the 22 October 2018 circular. The cap is tiered by the scheme's daily net assets, so the more money a fund gathers, the lower the percentage it is allowed to levy on the incremental slab. The structure that took effect on 1 April 2019 is set out below.

The slabs are marginal, not flat: a Rs 20,000 crore fund does not charge 1.60% on the whole book, it charges 2.25% on the first Rs 500 crore, 2.00% on the next Rs 250 crore and so on, producing a blended figure below any single slab rate. This is why very large index-tracking and flexi-cap schemes can advertise a headline TER well under 1%, while a young Rs 400 crore fund still sitting entirely in the first slab can charge up to 2.25%.

On top of the slab cap, the 2018 circular allows two named add-ons under Regulation 52(6A): up to 0.30% (30 basis points) of extra TER where a scheme draws at least 30% of gross new inflows, or 15% of its assets, from beyond the top 30 cities (the B-30 incentive), and up to 0.05% for schemes that do not charge an exit load. Goods and Services Tax on the investment management fee sits outside these caps. None of these add-ons change the core point: the slab defines the ceiling, and where a fund sits inside it is largely outside your control.

What you do control is the plan. SEBI made direct plans mandatory for every scheme from 1 January 2013, and a direct plan simply strips out the distribution commission that a regular plan pays to a mutual fund distributor. Because the TER is charged daily and reduces the Net Asset Value, a lower TER compounds into a permanently higher NAV path. The expense ratio is not a one-off fee — it is a recurring drag on every rupee for every year you stay invested.

Side-by-Side Comparison

The two plans are legally the same scheme with the same portfolio, the same benchmark index and the same manager. The distinction is entirely in the cost line, and therefore in the compounding that cost line suppresses.

To see what the gap is worth, take a Rs 10 lakh lump sum and an illustrative gross return of 12% a year used purely to demonstrate the mechanics of cost drag — this is not a forecast, and it is not an AMFI-published return. Assume a regular-plan TER of 1.75% and a direct-plan TER of 0.75%, the 1.0 percentage-point gap the briefing describes. Net returns become 10.25% and 11.25% respectively.

At 20 years the gap is Rs 13.93 lakh, which is 19.8% of the regular-plan corpus and larger than the original Rs 10 lakh invested. The same pattern holds for a monthly SIP: a Rs 10,000 monthly investment at the same 1.0-point gap ends roughly Rs 4.21 lakh apart after 15 years and about Rs 11.20 lakh apart after 20 years. You can reproduce either figure with the lumpsum calculator or the SIP calculator by entering the net return for each plan.

In pure annual-rupee terms, the drag is easy to feel. On a Rs 10 lakh holding, a 2.25% TER costs Rs 22,500 a year, the 1.05% floor costs Rs 10,500, and a 0.75% direct plan costs Rs 7,500 — a Rs 15,000 annual difference between the worst regular slab and a lean direct plan, deducted whether the fund rises or falls that year. Over a working lifetime, that recurring deduction is the single most controllable variable in your equity portfolio.

Tax Treatment

The TER you pay does not change how your gains are taxed, but plan choice interacts with tax in one important way discussed below. First, the rates. Equity-oriented mutual funds are taxed identically for regular and direct plans, under the framework revised by the Union Budget on 23 July 2024.

Long-term gains on listed equity funds are taxed at 12.5% under Section 112A, but only on the amount exceeding Rs 1.25 lakh of such gains in a financial year, and the benefit of indexation is not available on this asset class after 23 July 2024. Short-term gains are taxed at a flat 20% under Section 111A, with no basic-exemption cushion for the gain itself. These rates and provisions are published on the Income Tax Department portal at incometax.gov.in and apply to units of equity funds regardless of whether you bought the regular or direct plan.

There is one tax cost that is specific to switching. Moving from a regular plan to the direct plan of the same scheme is not an administrative toggle; it is a redemption of the regular-plan units followed by a fresh purchase of direct-plan units. That redemption is a taxable transfer, so any gain crystallises then and there — long-term gains above Rs 1.25 lakh at 12.5% under Section 112A, and short-term gains at 20% under Section 111A. An investor sitting on large unrealised gains should therefore weigh the one-time tax on switching against the years of TER saving that follow, rather than assuming the switch is free.

Note also that the higher NAV path of a direct plan means a slightly larger rupee gain to eventually tax — but a larger post-tax corpus in every scenario, because a 12.5% or 20% tax on a bigger number still leaves more than a smaller number left untouched by the same rate. The tax rate is neutral between plans; the after-cost corpus is not.

Who Should Pick Which

The regular-versus-direct decision is not automatically won by the cheaper plan, because the commission inside a regular plan is, in principle, paying for advice and hand-holding. The right choice depends on whether you value that service at more than the 1.0 percentage-point drag it costs — a drag worth Rs 6.27 lakh over 15 years on a Rs 10 lakh holding, as computed above.

Choose the direct plan if you are comfortable selecting and reviewing your own funds, can use tools such as the SIP calculator and lumpsum calculator to model outcomes, and do not need a distributor to place or monitor transactions. Self-directed investors with a 10-year-plus horizon capture the full 1.0-point saving, which is why the 20-year gap reaches Rs 13.93 lakh in the table above. If you want advice, a SEBI-registered investment adviser charging a transparent fee-only rate can sit alongside direct plans, keeping the product cost low while paying separately and visibly for guidance.

Choose the regular plan if you genuinely rely on a distributor to keep you invested through volatility, rebalance, and complete paperwork, and if the value of that behavioural coaching exceeds the drag. Behaviour matters: an investor who panics and redeems a direct-plan holding during a drawdown can lose far more than the 1.0-point TER saved, so the cheapest plan is not the best plan for someone who needs a steadying hand. For ELSS tax-saver funds specifically, the same logic applies, and you can compare post-cost outcomes on the ELSS calculator before deciding.

A middle path suits many investors: start new money in direct plans to stop the drag immediately, and leave legacy regular-plan units with large embedded gains in place until the one-time switching tax under Sections 111A and 112A is outweighed by future savings. This avoids crystallising a 12.5% or 20% tax bill in a single year while still steering fresh contributions to the lower-cost side of SEBI's TER line.

FAQ

What exactly is the Total Expense Ratio?

The TER is the annual percentage of a scheme's assets charged to run the fund — investment management fees, administration, registrar and distribution costs. It is governed by Regulation 52 and capped by SEBI's 22 October 2018 circular at 2.25% falling to 1.05% for equity schemes, and it is deducted daily from the NAV rather than billed separately, so most investors never see it as a line item.

Why is a direct plan's TER lower than a regular plan's?

A direct plan excludes the distribution commission that a regular plan pays to a mutual fund distributor. SEBI mandated direct plans for every scheme from 1 January 2013 for exactly this reason, and the resulting gap is typically around 1.0 percentage point on equity funds — the same 1.0 point that compounds to Rs 6.27 lakh over 15 years on a Rs 10 lakh holding in the arithmetic above.

Do large funds always charge less than small funds?

Not on a flat basis, but the slab structure means a fund's blended TER falls as its assets grow, because incremental money is charged at lower slab rates down to the 1.05% floor above Rs 50,000 crore of daily net assets. A Rs 400 crore fund sitting entirely in the first slab can charge up to 2.25%, whereas a very large scheme blends toward the floor.

Does the TER change how my gains are taxed?

No. Equity fund gains are taxed the same for both plans — 20% short-term under Section 111A and 12.5% long-term above Rs 1.25 lakh under Section 112A, per the rates on incometax.gov.in after 23 July 2024. TER affects the size of your corpus, not the rate applied to its gains, though a lower-cost direct plan leaves a larger after-tax amount in every case.

Is switching from a regular to a direct plan a taxable event?

Yes. A switch is treated as a redemption plus a fresh purchase, so any gain is realised at that point — long-term gains above Rs 1.25 lakh at 12.5% under Section 112A and short-term gains at 20% under Section 111A. Weigh that one-time tax against the years of TER saving before switching a holding that carries large unrealised gains.

What is the B-30 add-on I sometimes see mentioned?

Under Regulation 52(6A), SEBI allows up to 0.30% of additional TER where a scheme draws at least 30% of gross new inflows, or 15% of assets, from investors beyond the top 30 cities. It is an incentive to widen mutual fund penetration and sits on top of the slab cap, alongside a permitted 0.05% for schemes that levy no exit load.

How much does a 1% TER difference really cost over a lifetime?

On a Rs 10 lakh lump sum at an illustrative 12% gross return, a 1.0 percentage-point TER gap costs about Rs 2.51 lakh over 10 years, Rs 6.27 lakh over 15 years and Rs 13.93 lakh over 20 years. On a Rs 10,000 monthly SIP the 20-year gap is roughly Rs 11.20 lakh — figures you can reproduce on the SIP and lumpsum calculators by entering each plan's net return.
