What's the right capacity-planning model for a 50-rep org?
Start with: 50 reps × $300K quota (mid-market) = $15M target. Add 30% for expansion + CSM upsells = $19.5M total target. Plan hires: every $3M new ARR target needs 1 new rep (assuming 18-month payback). Adjust for tenure, region, and expansion capacity.
The capacity formula:
Total Sales Capacity = (# Reps) × (Avg Rep Quota) + (Expansion Quota) + (Upside %)
Example: 50 reps × $300K (mid-market quota) = $15M base. + $5M expansion revenue (CSM/expansion reps) = +$5M. + 20% upside (top 20% of reps close 130% attainment) = +$3M. Total planned capacity = $23M.
If your current ARR is $15M and target is $30M, you need: (30M - 15M) ÷ $300K per rep = 50 new reps over 24 months (not all at once). But expansion picks up 30% of that, so more like 35 net-new sales reps.
Capacity model by role (50-rep org breakdown):
| Role | Headcount | Avg Quota | Total Capacity | Notes |
|---|---|---|---|---|
| AE (New Logo) | 30 | $400K | $12M | Enterprise / mid-market motion |
| AE (SMB) | 10 | $200K | $2M | High-volume, shorter cycle |
| Expansion / CSM | 5 | $600K | $3M | Upsell + cross-sell, longer tenure |
| Director / Manager | 5 | N/A | Oversight | 1 director per 10 AEs |
| TOTAL | 50 | $300K avg | $17M | (Headcount-weighted) |
If you want to reach $25M ARR: add 6–8 AEs + 1 expansion manager. If you want to reach $50M ARR: double down on expansion hiring (move from 5% of team to 15%).
Capacity planning guardrails:
- Ramp time (6 months). A new AE generates 0% of quota in month 1, 25% in month 3, 75% in month 6, 100% by month 9. If you hire 10 AEs in January, don't forecast their full quota until October.
- Productivity curve.
- Tenure 1 year: 80% of quota (getting up to speed, learning deals).
- Tenure 2 years: 100% of quota (dialed in).
- Tenure 3+ years: 115% of quota (deep relationships, efficiency).
- Use this to adjust for team age. A team with 50% tenure <1 year is 10% below capacity.
- Territory design. 1 rep per $300–500K in market opportunity (addressable accounts in territory × ASP). If your territory only has $1M opportunity and you assign a $300K quota rep, they'll struggle.
- Manager bandwidth. 1 manager per 8–10 reps. At 50 reps, you need 5–6 managers. Each manager can coach 6 hours/week (1 on 1s, team coaching, forecasting). If you have 5 managers coaching 10 reps each, that's 5 hours per rep per month—tight but doable.
Hiring plan to go from $15M to $30M (18 months):
| Quarter | ARR Target | New Reps Needed | Total Headcount | Notes |
|---|---|---|---|---|
| Q1 (now) | $16M | 4 AEs | 54 | First wave |
| Q2 | $18M | 4 AEs | 58 | Second wave |
| Q3 | $21M | 5 AEs + 1 Expansion | 64 | Start expansion hiring |
| Q4 | $24M | 4 AEs + 1 Expansion | 69 | Build expansion bench |
| Q1+1 | $27M | 3 AEs + 1 Expansion | 73 | Focus shift to expansion |
| Q2+1 | $30M | 2 AEs + 1 Expansion | 76 | Stabilize |
Capacity check every quarter:
- Is each rep hitting 90%+ of their quota? (If <80%, territory or skill problem.)
- Are new reps ramping to 75% by month 6? (If <50%, hiring or onboarding is broken.)
- Is expansion revenue growing 30%+ YoY? (If <20%, not investing enough in retention.)
- Is ARR-per-employee staying 150K–200K? (If dropping, you're over-hiring relative to growth.)
Action: Build a simple capacity model in Excel. Plug in your current reps, average quota, growth target. That model tells you exactly how many reps to hire and when. Update quarterly. Don't let hiring drift ahead of this plan (it kills efficiency).
