What is ramp time?
Ramp time is how long a new seller takes to reach full productivity. Companies define full productivity in different ways, often as the first month or quarter in which a new hire produces at the level of tenured peers. Ramp is shaped by sales cycle length, product complexity, and how much help the new seller gets.
Why it matters to a revenue leader
Every month of ramp is a month of pay without full production, so ramp time sits inside every hiring plan and capacity forecast. In commercial services, long project cycles and technical knowledge can stretch it. Research by Phillip Wiseman, Michael Ahearne and colleagues found that new salespeople onboarded through manager-led field training sold about 23.5% more than peers who went through a centralized program, and the gain grew when managers led fewer people. Zoltners, Sinha and Lorimer also name the supervisor's attention to onboarding and early success as the biggest factor in keeping new hires.
How to calculate it
Ramp time = months from start date to the first period in which the seller's bookings reach the agreed level for tenured peers.
Common mistake: measuring only the hires who stayed, which makes ramp look faster than it is.
Example
Fictitious numbersA fire protection company's tenured sellers book about $100,000 a month. A new hire books $20,000 in month three, $60,000 in month six and $100,000 in month nine. Ramp time is nine months, so a seller hired in April produces far less than a tenured seller in that year's plan.
"What is our real ramp time, counting the hires who left before they ramped?"
