Ramp-adjusted capacity is the selling capacity a team will actually deliver in a period once new hires are counted at the productivity they will reach during that period rather than at full quota. It converts headcount into productive rep-months, which is the unit a revenue plan can be built on.
What Headcount Plans Miss
A headcount plan says the team ends the year at 24 reps. That statement is true and close to useless for revenue planning, because a rep who started in March and a rep who started in October both count as one head.
The gap is large. A rep hired in month 10 of a 12-month plan delivers almost nothing in that plan year while consuming a full seat of cost. Plans built on ending headcount routinely commit to numbers the team was never staffed to produce, then the miss gets attributed to execution.
Computing the Adjustment
Build the ramp curve from your own closed-won history by hire cohort, then apply it month by month.
A simplified curve shows the mechanic. Your own numbers will differ.
| Month since start | Example productivity | Contribution |
|---|---|---|
| 1 to 2 | 0% | Onboarding and training |
| 3 | 25% | First qualified opportunities created |
| 4 | 50% | Early-stage pipeline building |
| 5 | 75% | First closes land |
| 6+ | 100% | Fully ramped |
Stack It With the Attrition Adjustment
Ramp is the first discount. Attrition is the second. A rep who leaves in month seven takes their remaining productive months out of the plan, and the backfill re-enters the ramp curve at zero. Apply ramp first, then attrition, then the vacancy gap between departure and backfill start. Teams that model only one of the two land consistently high.
Where the Forecast Feels It
ORM decomposes a quarter into deals already in pipeline on day one, deals created and closed inside the quarter, and deals pulled forward from later periods. New reps contribute almost nothing to the second bucket in their first months, because creating and closing inside a single quarter requires the relationships and instincts they are still building.
That is why an unadjusted capacity plan distorts the in-quarter creation assumption specifically. Coverage from carry-over pipeline can look fine while the create-and-close engine is running short. Feed ramp-adjusted capacity into the plan before setting the creation target, and check it against pipeline coverage rather than assuming a headcount number covers it.

Frequently Asked Questions
What is ramp-adjusted capacity?
It is planned selling capacity with each rep weighted by the productivity they will actually deliver during the period. A rep who starts in month two of a four-quarter plan and takes six months to ramp contributes well under one full rep-year of capacity.
How do you calculate ramp-adjusted capacity?
Assign each ramp month a productivity percentage from your own historical ramp curve, sum those percentages across every rep and month in the period, then multiply by full-quota productivity per rep. The result is productive rep-months rather than headcount.
Why do headcount plans overstate capacity?
Because they count a hire as a full seller from the start date. A rep hired in March and a rep hired in October both show as one head in the annual plan, and they deliver very different revenue.
Should ramp adjustment and attrition adjustment both be applied?
Yes, and in that order. Discount new hires for ramp, then discount the ramped population for expected attrition and the vacancy period before a backfill produces. Applying only one of the two consistently overstates the plan.
