Contact Center Shrinkage: Full Guide for 2025

If you manage a contact center, you’ve probably noticed that not everyone is available all the time—even when they’re scheduled to be. It happens more often than we’d like, and it affects everything from staffing to performance. That’s where understanding shrinkage really starts to matter.

What is Contact Center Shrinkage?

Contact center shrinkage is basically the time when agents are scheduled to work but, for whatever reason, aren’t actually available to take calls or chats. Could be breaks, training, sick leave, meetings—you name it.

So even though they’re technically on the clock, they’re not helping customers at that moment. And yeah, that would add up.

Keeping track of contact center shrinkage helps with planning ahead, avoiding last-minute staffing issues, and making sure customers aren’t stuck waiting around forever.

Understanding Shrinkage in Detail

In simple terms, shrinkage in a contact center is the time agents are unavailable to take calls, even though they’re scheduled. To manage it properly, it’s important to break it down.

There are two main types of shrinkage in BPO—Planned and Unplanned.

1. Planned shrinkage

Planned shrinkage includes things you can predict, like breaks, training sessions, coaching, or team meetings. These are built into the schedule, so you usually know when they’re happening.

2. Unplanned shrinkage 

Unplanned shrinkage is the trickier part. This includes unexpected absences, sick leaves, logging in late, long wrap times, or even technical issues like system outages. These can throw off staffing if not accounted for.

Shrinkage vs Attrition

Now, a lot of people mix up contact center shrinkage and attrition, but they’re not the same. Shrinkage is short-term and temporary—people are still employed but just unavailable. Attrition means people have actually left the company, and their positions need to be refilled.

Understanding these differences helps in tracking agent availability more accurately and improving overall workforce planning. Keeping shrinkage in your contact center under control goes a long way in hitting service levels without burning out your team.

Calculating Contact Center Shrinkage

To manage your team better, you need to know how to calculate contact center shrinkage. It’s not as complicated as it sounds.

Here’s the basic formula:

Shrinkage (%) = [Total Unavailable Time / Total Scheduled Time] × 100

shrinkage and attrition formula in BPO

Let’s say an agent is scheduled for 8 hours but spends 2 hours in training, meetings, or on break. That’s 2 hours of shrinkage.

(2 / 8) × 100 = 25% shrinkage

You can use this same formula for an entire team by adding up the total unavailable time for all agents and dividing it by the total scheduled time.

Knowing your contact center shrinkage percentage helps you plan better. It tells you how many extra agents you need to meet your service levels, even when some team members aren’t available. It’s a small formula with a big impact.

Benchmarks and Industry Standards

Understanding contact center shrinkage is one thing—knowing how your numbers stack up is another. So, what’s “normal” when it comes to shrinkage?

Contact Center Shrinkage Standards Across Industries

Across industries, shrinkage rates usually fall between 30% and 35%, but it really depends on your business type. For example, BPOs with complex operations may see higher shrinkage due to training and client meetings, while e-commerce support centers might have lower numbers thanks to fewer internal sessions.

Here’s a rough benchmark by industry:

1. Retail/E-commerce contact centers: 25%–30%

2. Healthcare support teams: 30%–35%

3. Tech/BPO contact centers: 35%–40%

A shrinkage rate under 30% is generally considered healthy. Anything consistently above 40% might point to deeper issues—like poor scheduling, excessive meetings, or high absenteeism.

Comparing Shrinkage Rates with Yours

To compare your shrinkage rates, start tracking daily and weekly trends. Use a call center shrinkage calculator and compare your numbers to industry reports or peer benchmarks. Just make sure you’re comparing with centers that are similar in size, region, and support type.

By regularly reviewing benchmarks, you’ll know when to adjust schedules, improve workforce planning, or address any red flags in your operations.

Managing and Reducing Contact Center Shrinkage

Managing contact center shrinkage isn’t about eliminating it completely—it’s about understanding and minimizing it. Here’s how to do that effectively:

1. Track it Regularly

The first step is to measure shrinkage consistently. Use a simple contact center shrinkage formula weekly or bi-weekly. Tracking metrics helps you spot trends early—like if shrinkage peaks on certain days or during specific shifts. Data is your friend here.

2. Improve Scheduling

One of the biggest reasons for planned shrinkage is poor scheduling. If everyone’s in training or on break at the same time, you’ll see major drops in coverage. Spread out activities like coaching sessions, meetings, and breaks so there’s always enough staff available to handle calls.

3. Use WFM Tools

Workforce Management (WFM) software can simplify your life. These tools help forecast demand, automate shift planning, and ensure optimal staffing. When used well, they can drastically reduce both planned and unplanned shrinkage.

4. Find the Root Causes

Unplanned shrinkage often hides bigger problems. Maybe agents are disengaged, burned out, or confused about expectations. Or maybe there are tech issues delaying login times. Talk to your team. Understand what’s really going on and fix it at the source instead of just covering it up.

5. Offer Flexibility

Everyone works differently. Giving agents a say in their schedules—like preferred shifts or remote options—can reduce no-shows and last-minute leaves. A little flexibility shows trust and can improve overall attendance.

6. Use ConvoZen.AI for Real-Time Insights

ConvoZen.AI helps identify early signs of shrinkage through dashboards, reports, and behavior trends. You can spot when agent productivity dips or when certain shifts have frequent no-shows—before it becomes a bigger issue. It’s like having a smart assistant that watches out for your team.
