A distributor has Rs 18,000 crore of AUM earning 0.65% trail, 900 relationship managers costing Rs 9 lakh each a year and Rs 20 crore of other costs. What AUM does each manager need to break even, and what happens if trail is cut by 10 basis points?

Each manager needs about Rs 17.3 crore of assets to break even, against Rs 20 crore today, so the business earns only Rs 16 crore on Rs 117 crore of revenue. A 10 basis point trail cut removes Rs 18 crore of revenue, turns that into a loss of Rs 2 crore and lifts breakeven to about Rs 20.4 crore per manager. Restoring the old profit at the lower trail would mean about 200 fewer managers. A thin margin turns a small fee cut into a loss.

Start with the whole. Rs 18,000 crore at 0.65% is Rs 117 crore of trail. Managers cost 900 x Rs 9 lakh = Rs 81 crore, and other costs are Rs 20 crore, so profit is Rs 16 crore, a margin of 13.7% of revenue. A neighbourhood grocer who keeps two rupees of every fourteen he takes in lives close to the line; one supplier squeezing his margin decides whether he makes money that year. Distribution looks the same: large revenue, almost all of it spent on people.

Put each manager's cost on one line. Salary of Rs 9 lakh plus a share of other costs, Rs 20 crore over 900, about Rs 2.2 lakh, gives Rs 11.2 lakh a year. At 0.65% trail, a manager pays for himself only with about Rs 17.3 crore of client assets. Today the average is Rs 20 crore, so the cushion is under Rs 3 crore per head. Managers with smaller books are being carried by those with larger ones.

Trail falls from 0.65% to 0.55%, a cut of 15% in revenue, to Rs 99 crore. Costs do not move. A profit of Rs 16 crore becomes a loss of Rs 2 crore, and the breakeven book rises to Rs 20.4 crore per manager, above today's Rs 20 crore. The cut is larger in rupees, Rs 18 crore, than the entire profit. That is operating leverage in its plainest form.

Three levers, each with a cost. Fewer managers with larger books: at 0.55% the business breaks even with about 878 managers and needs about 700 to earn the old Rs 16 crore, so restoring profit means losing about 200 people and reassigning their clients, some of whom will leave. A better asset mix: equity schemes pay higher trail than debt, so shifting the book towards equity raises the average rate but also raises revenue's sensitivity to markets. A different model: charging clients a fee for advice instead of relying on commissions changes the regulatory category and the client conversation. The view: the business is too thin to absorb a fee cut without restructuring, and the first job is to rank managers by book size and cost, because the average hides the ones losing money. The limit: costs are not fully fixed, since incentives fall with revenue, so the real loss would be smaller.
