Sales capacity planning
In short
Sales capacity planning is the process of working out how many sales reps, and how much of their productive time, a company needs to reach a revenue goal. It combines quota, ramp time, attrition, and win rates into a headcount plan.
It works backward from the target. Rather than guessing how many reps to hire, you estimate what each ramped rep can realistically close and determine how many reps, hired by when, the plan requires. It differs from quota setting, which divides the target among reps once capacity is known.
Inputs to the model
- Revenue target: The new bookings the company needs this period.
- Productivity per ramped rep: Average bookings a fully ramped rep closes, from past data.
- Ramp time: Months until a new rep reaches full productivity, and what share they deliver while ramping.
- Attrition: Expected rep turnover and how long seats stay empty.
- Win rate and deal size: Used to check that the pipeline can support the target.
A simple example
Say the target is 5 million. A ramped rep closes about 500,000 a year. The plan needs ten ramped reps. The team has seven ramped reps, and one is likely to leave. Two new hires starting in month three would deliver only part of their potential in year one. The model shows a gap, so you can decide to hire earlier, hire more, or lower the target.
These figures are illustrative; build the model from your own history.
Steps to build a plan
1. Calculate ramped productivity
Use realistic averages, not top performers.
2. Layer in ramp and attrition
Model each hire by start month and the output they provide while ramping.
3. Check the pipeline side
Capacity to close is useless without opportunities. Compare required pipeline with what marketing and SDRs can create.
4. Add a buffer and revisit
Plan for misses, then update quarterly with actuals.
Common mistakes
- Assuming new reps are productive at once: Ramp delays are the most common source of misses.
- Ignoring attrition: Empty seats cut capacity.
- Planning headcount without pipeline: More reps do not create more demand.
- Using best-rep productivity: Averages are safer.
- One-time planning: Update the model as results arrive.
Sales capacity planning FAQs
What is sales capacity planning?
Sales capacity planning is calculating how many productive sales reps a company needs to reach a revenue target. It uses quota, ramp time, attrition, and win rates to decide how many reps to hire and when.
How do you calculate sales capacity?
Multiply the number of ramped reps by their expected productivity, then add partial output from reps still ramping and subtract expected attrition. Compare the total with your revenue target to find any gap and plan hires to close it.
What is the difference between sales capacity planning and quota setting?
Capacity planning decides how many reps you need and when to hire to hit the target. Quota setting then divides the target across reps and territories. Doing capacity planning first keeps individual quotas realistic.
Why does ramp time matter for sales capacity?
New reps contribute little revenue while they learn the product, build pipeline, and finish a full sales cycle. Ignoring ramp makes a plan overstate capacity, so teams that hire late often miss their target.
