Loss Capacity
Definition
Loss Capacity is the total amount of selling capacity that has been lost to attrition (terminations, resignations) and temporary leaves during a measurement period. It represents the revenue-generating potential that departed or absent employees took with them.
Formula
Loss Capacity = Σ (Departed/LOA Employee Annual Quotas)
Includes:
- Voluntary resignations
- Involuntary terminations
- Leaves of absence (LOA)
- Retirements
Excludes:
- Future planned departures (not yet happened)
- Internal transfers (capacity stays in company)
Worked Example: North America East Q4 2025
Departures during Q4 2025:
| Employee | Type | Date | Annual Quota | Capacity Lost |
|---|---|---|---|---|
| Tom | Resignation | Sept 30 | $1.4M | $1.4M |
| John | Resignation | Oct 15 | $1.2M | $1.2M |
| Mike | Termination | Nov 1 | $1.0M | $1.0M |
| Lisa | Resignation | Nov 15 | $1.4M | $1.4M |
| Sarah | LOA (Parental) | Dec 1 | $1.2M | $1.2M (temporary) |
Loss Capacity (Q4) = $1.4M + $1.2M + $1.0M + $1.4M + $1.2M = $6.2M
Note: Sarah's LOA is temporary loss (she's returning), but still counts as Loss Capacity for Q4.
Loss Capacity vs Other Metrics
Loss Capacity vs Attrition Rate
Loss Capacity = Total capacity lost ($6.2M)
Attrition Rate = Loss / Beginning Capacity
Attrition Rate = $6.2M / $11.0M = 56.4%
Difference:
- Loss Capacity: Absolute amount lost
- Attrition Rate: Percentage of starting capacity
Loss Capacity vs Unrecovered Gap
Loss Capacity = $6.2M (what we lost)
Recovered (Backfills) = $0.9M (what we regained)
Unrecovered Gap = $6.2M - $0.9M = $5.3M (what remains lost)
Difference:
- Loss Capacity: Total lost
- Unrecovered Gap: Lost minus recovered
Loss Capacity vs Revenue Impact
Loss Capacity = $6.2M annual quota
Quarterly Impact = $6.2M / 4 = $1.55M per quarter
But actual revenue impact depends on:
- When in quarter they left (mid-quarter = partial loss)
- Their actual attainment % (not 100%)
- Whether backfills were hired
Measuring Loss Capacity
Annual Loss Capacity
Sum all departures across the full year:
Q1 Loss: $2.0M
Q2 Loss: $2.3M
Q3 Loss: $2.5M
Q4 Loss: $6.2M
────────────────
Annual Loss Capacity: $13.0M
Interpretation: Lost $13.0M of annual quota capacity over the year.
Quarterly Loss Capacity
Focus on a single quarter to understand period-specific impact:
Q4 2025 Loss Capacity: $6.2M
Q4 2025 Beginning Capacity: $11.0M
Q4 Attrition Rate: 56.4% (crisis level)
Month-by-Month Loss Tracking
| Month | Departures | Cumulative Loss |
|---|---|---|
| Sept | 1 (Tom) | $1.4M |
| Oct | 1 (John) | $2.6M |
| Nov | 2 (Mike, Lisa) | $5.0M |
| Dec | 1 (Sarah LOA) | $6.2M |
Insight: Loss accelerated in Nov-Dec (holiday season turnover spike)
Types of Loss Capacity
1. Permanent Loss (Attrition)
Voluntary:
- Resignations
- Retirements
- Career changes
Involuntary:
- Performance terminations
- Layoffs
- Restructuring
Impact: Permanent capacity loss, requires backfill to recover
Example:
Tom resigned: $1.4M permanent loss
→ Need to hire backfill to recover
2. Temporary Loss (LOA)
Leave types:
- Parental leave
- Medical leave
- Sabbatical
- Military leave
Impact: Temporary capacity loss, employee returns
Example:
Sarah on 3-month parental leave: $1.2M temporary loss
→ No backfill needed, capacity returns automatically
→ But still impacts Q4 performance
3. Partial Loss (Mid-Period Departures)
When employees leave mid-quarter, capacity loss is prorated:
Example:
John leaves Oct 15 (halfway through Q4)
Annual quota: $1.2M
Q4 quota: $300K
Remaining Q4 capacity lost: ~$150K (half the quarter)
For Loss Capacity tracking: Still count full annual quota ($1.2M), but note actual Q4 impact is lower.
Why Loss Capacity Matters
1. Quantifies Attrition Impact
"We lost 5 people in Q4"
→ How bad is that?
"We lost $6.2M of Loss Capacity in Q4"
→ Much clearer impact
2. Drives Hiring Urgency
Loss Capacity: $6.2M
Average Quota: $1.2M
→ Need to hire 5-6 people to replace lost capacity
→ But with ramp, will take 5-6 months to fully recover
3. Justifies Backfill Budget
To Finance: "We need to hire 5 backfills"
Why? "We lost $6.2M of capacity, need to restore it"
Cost: 5 × $120K salary = $600K investment
ROI: Recover $6.2M revenue potential
4. Reveals Trends
Year-over-year comparison:
| Year | Annual Loss Capacity | Trend |
|---|---|---|
| 2023 | $8.0M | Baseline |
| 2024 | $11.0M | +37.5% worse |
| 2025 | $13.0M | +18% worse |
Insight: Attrition problem is accelerating, need retention initiatives
Tracking Loss Capacity by Segment
By Role
| Role | Loss Capacity | % of Total |
|---|---|---|
| Enterprise AE | $3.8M | 61% |
| Mid-Market AE | $1.8M | 29% |
| SDR | $0.6M | 10% |
Insight: Enterprise AE attrition is disproportionately high
By Manager
| Manager | Loss Capacity | Team Size | Loss Rate |
|---|---|---|---|
| Michael | $4.0M | 6 people | 67% |
| Amanda | $1.2M | 4 people | 30% |
| David | $1.0M | 5 people | 20% |
Insight: Michael's team has critical retention issue
By Reason
| Reason | Loss Capacity | % of Total |
|---|---|---|
| Voluntary (resignation) | $4.0M | 65% |
| Involuntary (termination) | $1.0M | 16% |
| LOA (temporary) | $1.2M | 19% |
Insight: Most loss is voluntary turnover (retention problem, not performance)

Best Practices
1. Track in Real-Time
Update Loss Capacity immediately when:
- Employee gives notice
- Termination occurs
- LOA begins
Don't wait for monthly close.
2. Separate Permanent vs Temporary
Total Loss Capacity: $6.2M
├─ Permanent (attrition): $5.0M
└─ Temporary (LOA): $1.2M
Why: Different responses (backfill vs wait for return)
3. Report Both Annual and Actual Impact
Tom left Oct 15:
Annual Quota: $1.4M (Loss Capacity metric)
Q4 Impact: ~$175K (actual revenue at risk)
4. Compare to Historical Baseline
Current Quarter Loss: $6.2M
Historical Avg (last 4Q): $2.0M
→ 210% above normal (CRISIS)
Common Pitfalls
1. Only Counting Headcount
Mistake: "We lost 5 people"
Better: "We lost $6.2M of capacity (5 people)"
Why: Not all people have equal capacity (quotas vary)
2. Not Tracking LOA Separately
Mistake: Treating LOA same as permanent attrition
Reality: LOA is temporary, employee returns, no backfill needed
3. Forgetting Mid-Period Departures
Mistake: Only counting end-of-quarter headcount
Reality: Someone who left Day 1 has different impact than Day 89
4. Not Segmenting Loss
Mistake: "We lost $6.2M" (no additional context)
Better: "We lost $6.2M: 61% from Enterprise AE, 67% from one manager's team"
Why: Reveals specific problems to address
Loss Capacity in Capacity Planning
Beginning of Quarter (BoQ) to End of Quarter (EoQ) Flow
BoQ Capacity: $11.0M
Less: Loss Capacity: -$6.2M
Plus: Backfills Added: +$0.9M (partial ramp)
─────────────────────────────
EoQ Capacity: $5.7M
Forecasting Future Loss
Use Capacity at Risk to predict next quarter's Loss Capacity:
Q1 2026 BoQ Capacity: $5.7M
Predicted Q1 2026 Loss (13.5% rate): $770K
Plan for: $770K of Loss Capacity in Q1, need 1-2 backfills
