The Rep Ramp Rate Formula
The ramp rate formula converts expected attainment by month-on-book into a projected revenue contribution for each new hire. Build the curve by pulling historical attainment data from your CRM, grouped by month-on-book for a cohort of closed-out reps.``` Expected Monthly Contribution = Full Quota × Ramp Attainment % (for that month-on-book) ```
If a rep's full-ramp quota is $100,000 per month and your ramp curve shows 30% expected attainment in month two, that rep is expected to contribute $30,000 in month two.
Building the Ramp Curve
| Month on Book | Typical Expected Attainment | Notes |
|---|---|---|
| Month 1 | 0% to 10% | Training, onboarding, pipeline building |
| Month 2 | 20% to 35% | First deals entering late stage |
| Month 3 | 40% to 55% | Early closes from initial pipeline |
| Month 4 | 60% to 75% | Pipeline volume reaches steady state |
| Month 5+ | 80% to 100%+ | Approaching full productivity |
Actual vs. Expected Ramp
Track the gap between expected and actual ramp attainment by cohort. A rep consistently below the expected ramp curve by month three is a coaching signal. A cohort consistently below expected attainment is a hiring, onboarding, or territory signal.
``` Ramp Variance = Actual Attainment % - Expected Attainment % ```
Positive variance means the rep is ramping faster than the model predicts. Negative variance triggers review of territory quality, pipeline sourcing, or onboarding gaps.
Ramp Rate in Capacity Models
When building a sales capacity planning model, every new hire slot must be weighted by their ramp curve, not their full quota. A rep hired in Q1 may contribute only 20% to 50% of their annual quota in the year of hire, depending on the ramp curve and hire date.
This feeds directly into attrition-adjusted capacity calculations. If you are also losing reps, you are simultaneously losing their full productivity and replacing it with ramping productivity. The net capacity effect is significantly larger than headcount numbers alone suggest.
The quota ramp schedule formalizes this expectation operationally so that reps, managers, and finance share the same productivity assumptions.
Frequently Asked Questions
How do you calculate sales rep ramp rate?
Establish a ramp curve by tracking actual quota attainment for each new hire by month-on-book, then average across a cohort of reps to produce expected attainment at each month. For example, if reps in their third month average 40% of full quota, month 3 expected attainment is 40%.
What is the difference between ramp period and time-to-full-productivity?
The ramp period is the defined window during which a rep is on a reduced or graduated quota. Time-to-full-productivity is the actual observed point at which a rep consistently hits full quota. These often differ, and the gap is important: a 90-day ramp period does not mean reps are productive on day 91.
How does ramp rate affect sales capacity planning?
New hires do not contribute their full quota in the hiring period or often the quarter after. In a capacity model, you must weight each new hire's contribution by their expected ramp attainment by month-on-book. Ignoring ramp leads to over-counting productive capacity and missing revenue targets.
