Ten people at ₹84.6 lakh each is ₹8.46Cr. Double the team to twenty and the plan assumes ₹17Cr. The arithmetic on the slide is clean. It is also almost never what happens.
Almost nobody on your team produces the average
Rank your team by attainment
Rank every salesperson from highest to lowest attainment and the shape is nearly always the same: three people carry most of the number, and the other seven sit far below. The average of ₹84.6 lakh is real as a statistic and almost meaningless as a planning input, because it is being pulled upward by a small number of outliers.
the actual median
That is what your eleventh hire is statistically likely to do — not the ₹84.6L average the plan was built on. Ten hires at the median produce roughly ₹3.5Cr, not ₹8.46Cr.
Now the part that hurts
Twenty salespeople need two managers, and in most companies those managers come from the top three performers — the very people producing far above the median.
But he'll still sell.
He will. That's the problem.
Selling has deadlines. Coaching does not. So when the month is tight — and the month is always tight — the promoted seller works his own deals instead of developing the seven people below the median who actually need coaching. The company ends up paying for two roles and receiving less than one full role in return.
You end up with a ₹2Cr seller doing ₹1.2Cr, and a manager doing about a third of a manager's job
It compounds from there
The best leads keep routing to him, because he is still the one who closes them. The seven people below the median stay below the median, because the coaching that would move them is competing with — and losing to — his own pipeline every month.
And the specific thing that made him ₹2Cr in the first place — his relationships, his instinct for a room — is precisely what cannot be taught to the seven people now reporting to him. You promoted the least systematic person on the team and asked him to build a system.
The math the founder never runs
This does not mean top performers should never become managers. It means the promotion should be tested against a specific question before it happens: is what makes this person successful a repeatable process, or a personal advantage that dies the moment it stops being exercised directly?
If it's a process
Qualification discipline, a specific way of progressing deals, a negotiation habit — these transfer. This person can genuinely make others better at the job.
If it's a personal advantage
Relationships built over years, instinct, a network only they have access to — these do not transfer through management. The promotion removes their output without replacing it with anything teachable.
Most founders promote on the wrong axis — attainment, not teachability — because attainment is the number on the dashboard and teachability requires actually watching how someone works, not just what they produce.
Then he resigns in year two, and you lose a manager and your best seller in one conversation
That is the actual cost of getting this wrong, and it rarely shows up on the same spreadsheet as the original hiring plan. Before doubling headcount, run the median math on what it will really produce. Before promoting the top performer, test whether what makes them good is something the other seven can actually learn.
