Headcount vs Capacity

The Problem

Many sales leaders track headcount when they should be tracking capacity. These are not the same thing.

Headcount = Number of people on the team Capacity = Amount of selling productivity those people can deliver

Why They're Different

Example: Two Teams

Team A:

  • 10 people
  • All fully ramped (9+ months tenure)
  • Producing at 100% capacity

Team B:

  • 10 people
  • 5 fully ramped (100%)
  • 3 at 6 months (60% ramp)
  • 2 just started (10% ramp)

Both teams have the same headcount (10 people), but very different capacity:

TeamHeadcountEffective Capacity
Team A1010.0 RRE
Team B107.0 RRE

Team B has only 70% of Team A's selling capacity despite having the same number of people.

The Ramp Problem

New hires don't produce at full capacity immediately. They go through a ramp period:

Month 1-3:  25% productivity (learning products, processes, territory)
Month 4-6: 60% productivity (building pipeline, closing first deals)
Month 7-9: 85% productivity (hitting stride)
Month 10+: 100% productivity (fully ramped)

During this time, they count as "1 headcount" but contribute less than "1.0 capacity."

Real-World Impact

Scenario: Hitting Headcount Target

Your plan called for 25 reps by end of Q4. You hit that target exactly. Success?

Not necessarily.

If you:

  • Started Q4 with 20 fully ramped reps
  • Lost 5 reps to attrition mid-quarter
  • Hired 10 new reps (5 backfills + 5 net new)

You now have:

  • Headcount: 25 people ✅
  • Capacity: 15 fully ramped + 10 ramping at 25% = 17.5 RRE ❌

You're 30% below target capacity despite hitting headcount target.

When to Use Each Metric

Use Headcount For:

  • Budget planning (salary costs, seat licenses)
  • Org chart reporting (spans of control)
  • Recruiting targets ("hire 10 AEs")
  • Workspace planning (desks, laptops)

Use Capacity For:

  • Quota setting (how much revenue can this team actually produce?)
  • Territory planning (do we have enough coverage?)
  • Capacity planning (are we understaffed or overstaffed?)
  • Performance forecasting (what's realistic attainment?)

Key Principle

"Headcount is who you pay. Capacity is what you get."

If you plan revenue based on headcount without accounting for ramp, you'll consistently miss forecasts.
