Shrinkage

What is Shrinkage?

Shrinkage refers to the percentage of time employees are unavailable for productive work, typically in call centers or customer service environments. It accounts for all non-working periods such as breaks, training, meetings, and absenteeism, impacting resource planning and customer experience.

Call Center Shrinkage Formula

Shrinkage is calculated as a percentage of total paid hours:
Shrinkage % = (Total Shrinkage Hours / Total Paid Hours) × 100
Where “Total Shrinkage Hours” is every paid hour an agent isn’t available to handle a customer interaction, and “Total Paid Hours” is every hour you pay agents for, whether they’re on a call or not.

Planned vs Unplanned Shrinkage

Shrinkage splits into two categories, and the split matters because one is largely controllable and the other isn’t:

• Planned shrinkage: Known in advance and schedulable, breaks, lunch, training sessions, team meetings, coaching, and scheduled time off.
• Unplanned shrinkage: Unscheduled and harder to forecast, unplanned absenteeism, system outages or downtime, emergency escalations, and excessive after-call work.

A healthy workforce management process schedules around planned shrinkage confidently and builds a buffer for unplanned shrinkage, rather than treating both as the same unpredictable loss.

Shrinkage Category Breakdown

Category	Example	Typical Hours (per 8-hour shift)
Breaks	Short paid breaks (morning/afternoon)	0.25 – 0.5 hrs
Lunch	Meal break	0.5 – 1 hr
Training & coaching	Onboarding, refreshers, 1:1 coaching	0.25 – 0.75 hrs
Team meetings	Huddles, briefings	0.15 – 0.3 hrs
System/technical downtime	Login issues, outages	0.1 – 0.3 hrs
Unplanned absenteeism	Sick leave, no-shows (amortized across the team)	Varies, 0.2 – 0.5 hrs equivalent
After-call work overflow	Wrap-up beyond standard ACW allowance	0.1 – 0.25 hrs

Worked Example: Shrinkage for a 50-Agent Team

Take a 50-agent team, each scheduled for an 8-hour (480-minute) shift, so total paid hours across the team are 50 × 8 = 400 hours per day. Suppose the team’s daily shrinkage adds up to:

• Breaks: 0.4 hrs/agent × 50 = 20 hrs
• Lunch: 0.75 hrs/agent × 50 = 37.5 hrs
• Training & coaching: 0.5 hrs/agent × 50 = 25 hrs
• Team meetings: 0.2 hrs/agent × 50 = 10 hrs
• System downtime: 0.15 hrs/agent × 50 = 7.5 hrs
• Unplanned absenteeism (team-wide equivalent): 12 hrs
• After-call work overflow: 0.15 hrs/agent × 50 = 7.5 hrs

Total shrinkage hours = 20 + 37.5 + 25 + 10 + 7.5 + 12 + 7.5 = 119.5 hours
Shrinkage % = (119.5 / 400) × 100 = 29.9%
At roughly 30% shrinkage, this team needs to schedule for meaningfully more than 50 “headcount-equivalent” hours of coverage to actually staff 400 productive hours, which is exactly what the benchmark below is used for.

2026 Shrinkage Benchmark

Most industry benchmarks put a healthy call center shrinkage rate at 30% to 35% of total paid hours. This is a widely cited rule of thumb rather than a single authoritative study, and the right number for your team depends on shift length, call type, and how much training and coaching your process requires. Shrinkage meaningfully above 35% is usually worth investigating, it often signals scheduling gaps, high absenteeism, or under-resourced training rather than an unavoidable cost of doing business.

A live, interactive version of this calculator would need to be built and embedded on the page itself, since a Word document can’t run one. Use this fill-in-the-blank version in the meantime, following the same 3 inputs any online shrinkage calculator asks for:

Input	Your Number	Formula
Total paid hours (agents × shift hours)	[fill in]	Number of agents × hours per shift
Total shrinkage hours (sum of the category breakdown above)	[fill in]	Add up breaks, lunch, training, meetings, downtime, absenteeism, and ACW overflow
Shrinkage %	[result]	(Total shrinkage hours / Total paid hours) × 100

Key Characteristics of Shrinkage

• Includes non-productive time: Time taken for breaks, training, and meetings that reduces available agent hours.
• Varies by organization: Shrinkage rates fluctuate depending on workforce policies and operational demands.
• Critical for workforce management: Used to calculate accurate staffing requirements and avoid customer wait times.
• Impacts service levels: High shrinkage can lead to understaffing and customer dissatisfaction.

Use Cases of Shrinkage in CX

• Optimizing agent scheduling: Adjusting shifts based on shrinkage to maintain consistent customer support.
• Predicting staffing needs: Forecasting agent availability to meet fluctuating call volumes efficiently.
• Improving customer wait times: Minimizing shrinkage helps ensure faster response and reduced hold periods.
• Analyzing operational efficiency: Identifying areas for process improvements and training to lower shrinkage.

Why Shrinkage Matters

• Enhances workforce accuracy: Precise agent availability planning.
• Improves customer satisfaction: Reduces wait times and service delays.
• Optimizes operational costs: Prevents overstaffing or understaffing scenarios.
• Supports proactive management: Enables better handling of agent productivity gaps.

How to Reduce Unplanned Shrinkage

• Track schedule adherence in real time: Real-time adherence monitoring catches agents drifting off-schedule before it compounds into a shrinkage problem.
• Review call quality, not just headcount: Poor calls drive longer after-call work and repeat contacts, both of which show up as shrinkage. AI-powered call quality analysis helps identify which calls are dragging down ACW time.
• Build absenteeism buffers into forecasts: Rather than treating no-shows as a surprise every time, forecast a realistic absenteeism rate based on historical data and staff slightly above the bare minimum.
• Give managers visibility into shrinkage trends: Shrinkage that’s rising month over month is a signal for whoever owns scheduling. See our call center manager guide for the KPIs that should be on that dashboard
