Trail commission
The commission an AMC pays a mutual fund distributor as a percentage of the current value of the investments they brought in, calculated daily and paid for as long as the investor stays invested.
In plain language
A mutual fund distributor earns from the AMC, not from the investor. The main — now effectively the only — form that payment takes is trail commission.
It is calculated as a percentage of the net assets attributable to the units sold by that distributor, worked out on daily balances and paid out periodically under the distributor's agreement with the AMC. Two features make it unusual:
- It follows the value of the investment, not the amount mobilised. If the investor put in Rs 10,000 and it has grown to Rs 15,000, trail is paid on Rs 15,000. Distributors benefit when markets rise — and earn less when they fall.
- It has no time limit. Unlike insurance, where an agent's commission runs for a limited number of years, trail commission is paid for as long as the investor's money is held in the fund.
The workbook frames trail as having a second purpose besides paying for mobilisation: to ensure the investor continues to receive regular updates and services from the distributor.
How it works
The daily formula.
Trail commission for the day = AUM × trail commission rate p.a. ÷ 365
The workbook's Table 6.1: a distributor mobilises Rs 10 lakh at an NAV of Rs 10.0000, so 1,00,000 units are allotted, with an assumed trail rate of 1 per cent a year. On 1 August the value is Rs 10,00,000 and the day's trail is Rs 27.40. As the NAV moves — Rs 9.8527 on 22 August gives Rs 26.99; Rs 10.1683 on 27 August gives Rs 27.86 — the daily amount moves with it. The month's total is Rs 853.13. The NAVs are randomly generated, not those of a real scheme.
The regulatory frame.
| Rule | Detail |
|---|---|
| Full trail model | Under the SEBI MF Master Circular of 20 March 2026, AMCs pay only trail commission in all schemes — no upfront commission or upfronting of trail, directly or indirectly, in cash or kind, through sponsorships or any other route |
| Form | Trail commission can be paid only in monetary terms |
| Frequency | Normally monthly or quarterly |
| Self-business | No commission on the distributor's own investments |
| Disclosure | Distributors must disclose to investors all commissions payable from competing schemes of other mutual funds they considered |
| Additional commission | For new individual investors from B-30 cities and new women investors, 1% of first lump sum (min holding one year) or of first-year SIP, capped at Rs 2,000, paid from the 2 bps set aside for investor education — in addition to trail |
| Change of distributor by investor | No commission to either old or new distributor; AMCs may consider paying the new one after a 12-month cooling off period (voluntary cessation of business by the old distributor is an exception) |
Contradictions in the workbook. (1) The Master Circular text bars "upfronting of any trail commission", but section 6.5.3 says "upfronting of trail commission is allowed only in case of SIP inflows". (2) The illustration says the distributor "may have been paid an initial commission" on Rs 10,000, although upfront commission is no longer permitted. (3) Table 6.1 is introduced as the calculation "for the month of July 2019" but its rows are August 2019. For a rule question, answer: trail only, with SIP inflows as the stated exception to upfronting.
The formula
Value of holding on a day = Units attributable to the distributor × NAV that day
Trail for the day = Value × annual trail rate ÷ 365
Trail for a period = Σ daily trail amounts
A worked example
Deepak, a distributor, has brought in Rs 40 lakh of equity fund assets across his clients, at an average trail rate of 0.80 per cent a year. Figures are illustrative.
A normal day.
Trail = 40,00,000 × 0.80% ÷ 365 = Rs 87.67
After a 25 per cent market rise, the same clients' holdings are worth Rs 50 lakh without a rupee of new money:
Trail = 50,00,000 × 0.80% ÷ 365 = Rs 109.59 a day
Over a year that is about Rs 40,000 instead of Rs 32,000. After a 25 per cent fall to Rs 30 lakh, it would be about Rs 24,000. His income moves with his clients' wealth, which aligns his interest with keeping them invested.
What does not earn trail.
- The Rs 6 lakh Deepak invested himself through his own ARN — self-business, no commission.
- A client who, on Deepak's urging, moved Rs 5 lakh of existing folios from another distributor's code to his — neither Deepak nor the old distributor is paid, and the AMC may consider paying Deepak only after 12 months.
What earns extra. A new woman investor in a B-30 town starts a Rs 5,000 monthly SIP through him. First-year SIP total Rs 60,000; 1 per cent is Rs 600, under the Rs 2,000 cap — paid on top of his trail.
Why NISM asks about it
Chapter 6 (Fund Distribution and Channel Management Practices), section 6.5, covers the full trail model, the concept of trail with Table 6.1, self-business, additional commission and transaction charges; section 6.10 covers change of distributor and the cooling off period. Expect a daily-trail computation (AUM × rate ÷ 365), a question on whether trail is based on amount invested or current value, and rule questions on self-business and change of distributor.
Common exam traps
- Trail is on current value (net assets), not on the amount originally mobilised.
- Daily trail = AUM × annual rate ÷ 365.
- Paid for as long as the money stays invested — no time limit, unlike insurance commission.
- Full trail model: no upfront commission, no upfronting of trail, no cash or kind incentives. The workbook separately allows upfronting for SIP inflows.
- No commission on self-business.
- Investor-initiated change of distributor: neither distributor is paid; the new one may be considered after a 12-month cooling off period.
- Additional B-30 / women investor commission is on top of trail, capped at Rs 2,000.
- Transaction charges have been withdrawn.
Where this is taught
Free preparation for NISM Series V-ARelated terms
- Net Asset ValueThe net assets of a mutual fund scheme divided by the number of units outstanding — what one unit of the scheme is worth on a given day, after every liability except the unitholders' own.
- AMFIThe Association of Mutual Funds in India — the association of all registered AMCs, which registers distributors through the ARN and sets codes of conduct, but is neither a regulator nor a self-regulatory organisation.
- Assets under ManagementThe total value of the money a scheme or a fund house manages — the current NAV multiplied by units outstanding — and the base on which the expense ratio is charged.
- Direct and regular plansThe two routes into the same mutual fund scheme: a direct plan with no distributor and a lower expense ratio, and a regular plan that pays distributor commission — same portfolio, separate NAVs.
- Systematic Investment PlanA facility to invest a constant amount into a scheme at regular intervals, which buys more units when the NAV is low and fewer when it is high and so averages the cost of acquisition down.
- Know Your DistributorAMFI's verification process for mutual fund distributors — document verification plus a biometric impression of the right index finger, traditionally at a CAMS Point of Service — completed before ARN registration.
- Total Expense RatioThe all-in annual cost of a mutual fund scheme as a percentage of daily net assets — the base expense ratio plus brokerage, transaction cost and statutory levies — charged to the scheme, not billed to the investor.
- Reverse charge mechanismThe GST rule under which the recipient of a service — not the supplier — pays the tax directly to the government, applied to AMCs paying GST on commissions to unregistered mutual fund distributors.
- Equal trail basisSEBI's rule that a Category III AIF may charge distribution or placement fee only as an equal trail — no upfront fee at all, and paid only out of the manager's own management fee.
- Execution only platformA SEBI-recognised digital platform that carries out subscription, redemption and switch transactions in direct plans of mutual fund schemes only — registered with AMFI (Category 1) or as a stock broker (Category 2).
- AMFI Registration NumberThe registration number AMFI allots to a mutual fund distributor after NISM certification and KYD. It must be quoted on a client's Regular Plan transaction for commission to be paid.
- Full trail modelSEBI's rule that AMCs pay distributors only trail commission in all schemes — no upfront commission and no upfronting of trail, in cash or kind, through sponsorships or any other route.
- Cooling off periodThe 12 months after an investor-initiated change of distributor code in a folio, during which no trail is paid to either distributor; only afterwards may the AMC consider paying the new one.
- Self-businessA distributor's own investment in a scheme they are empanelled to sell — on which no commission is payable, since commission compensates for mobilising someone else's money, not one's own.
- Recurring expensesThe ongoing fees and commissions a mutual fund scheme pays its constituents, charged as a percentage of AUM and deducted before NAV is struck — so higher recurring expenses mean lower investor returns.
