How the math works
The rep ramps up in a straight line to the full number of new accounts per month. Accounts they start working in a given month turn into revenue once the sales cycle has passed. Won accounts keep paying every month, less the share you lose each month.
Monthly cost is base salary plus benefits and taxes, travel and expenses, and commission on that month's revenue. Hiring and onboarding is charged once, in month one. Profit is revenue times gross margin, minus those costs.
This is a planning tool, not a forecast. Every territory is different, so treat it as a starting point for a real conversation.
