Defining service level call center and how it works

A service level call center tracks how fast and how well agents answer customer calls. Every job needs metrics to measure how people perform. As a result, teams learn which areas to improve and grow.

One key example is the key performance indicator (KPI) that managers use for call center agents. In short, it shows how efficient a team is. Call centers rank among the biggest users of KPIs today. So these numbers often guide how each agent improves.

One factor inside a KPI is the service level call center metric. Read on as we break down what it means and how it works.

What is a service-level call center?

A service level call center metric measures the share of calls answered well and fast within a set time. In short, it checks both quality and quantity of work for customer service. Most teams track it with KPIs over time. Generally, it includes:

• Percentage of calls answered
• Average time handled
• Average time of response
• Average time of resolution

It also covers other metrics that measure a quality customer experience. For call centers, service level shapes both customer satisfaction and agent output.

In what way? Check how many calls an agent answers using a service level metric. Based on this, you can lift call response, cut wait times, and reduce missed calls. As a result, you offer better service overall.

Hitting the service standard also raises lifetime customer value. In short, fast replies keep people happy. In turn, those people are more likely to come back. These same gains drive strong call center outsourcing results.

What are a service-level call center’s standards and benchmarks?

A strong service level call center needs clear standards and benchmarks. So below are the factors to weigh if you want more productive agents. Each one needs daily tracking to see how it shapes an agent’s efficiency.

Service level

The core standard is often 80/20 or 80/30. In other words, an agent must answer 80% of calls within 20 or 30 seconds.

However, some clients prefer a 90/10 scheme. Still, it varies by team. In fact, it is a great way to build speed and accuracy at once.

Average speed of answer

Speed of answer ties straight to service level. In short, clients want fast answers when they use an interactive voice response.

Average handle time

Another key factor is how long an agent spends on a call. The clock starts when a call hits the queue. It ends only after the agent finishes any after-call work.

After-call work

Right after a caller hangs up, the agent may still write a memo or log details. Depending on the process, this can take under 30 seconds. So agents should wrap up some of these tasks while closing the call.

Abandon rate

It helps to know how many calls drop due to poor staffing. In fact, the abandon rate links straight to how good your workforce management is.

Average time in queue

Managers must watch an agent’s average wait time. If it climbs each day, then the company likely needs more staff.

Occupancy

Every agent should learn to manage their occupancy at work. For example, 75% occupancy in an hour means 45 minutes on calls. The rest goes to short breaks.

Practical tips to reach the service level call center targets

Here are simple ways an agent can meet service level targets. First, reduce attrition. Next, use the right software. Finally, align your KPI goals.

Cut down on attrition

The right staff keeps the business running well. When people feel unhappy, they tend to quit.

As a result, attrition leaves you with less experienced staff. In short, all the time and money spent on hiring and training goes to waste. Agents with strong customer service skills are worth keeping on board.

Use call center software

There is nothing wrong with using tools to boost output. So call center software can help. In fact, it streamlines the work, lifts agent output, and improves results.

Below are the main types of software call centers use.

Automatic call distributor (ACD)

An ACD takes incoming calls and routes them to free agents at once. As a result, it cuts the time to pick up a call. In turn, it lifts service level and customer satisfaction.

Workforce management software (WFM)

A WFM keeps service level on track. It checks agent schedules and flags labor needs in real time.

Time tracking software

Software that tracks time is a key tool. For example, this software that tracks time shows how each agent performs. So it tells you what they do and where their time goes at work.

Align KPI goals

Every role has its own KPI goals. So aligning them is key to hit the service level target. In short, your KPI targets depend on each other and pull in the same direction. Watching your call center metrics keeps them in sync.

How is service level calculated in a call center?

You can calculate a service level call center in several ways. So here are five common formulas.

First formula

This is the first and simplest formula for service level:

Calls answered within threshold / Total calls answered x 100%

Second formula

This one counts all calls and abandoned calls while the threshold was positive:

Total calls answered within threshold + Calls abandoned within threshold / Total calls answered + Total calls abandoned x 100%

Third formula

Unlike the second, this one treats all abandoned calls as negative:

Total calls answered within threshold / Total calls answered + Total calls abandoned x 100%

Fourth formula

Here, it ignores abandoned calls before the threshold. Meanwhile, it treats those before the threshold as negative:

Total calls answered within threshold / Total calls answered + Total calls abandoned after threshold x 100%

Fifth formula

The last formula uses a threshold for short calls. So it counts abandoned calls before the threshold as positive:

Total calls answered within threshold + Calls abandoned within a shorter amount of time than the threshold / Total calls answered + Total calls abandoned x 100%

How to find the right service-level call center?

Service levels vary by field. So every call center sets a KPI that fits its work. In turn, this keeps the workflow productive and on target.

It also helps to classify abandoned calls the right way. In short, you must know if they count as missed or ignored. Because of this, businesses should watch closely, since it shapes agent performance.

The right formula depends on abandoned calls in the time frame. It also depends on whether you treat them as positive or negative. One tip: pick a time interval, since it changes the result. A focus on first call resolution also lifts your numbers.

Next, set how often you check monitoring the performance. Daily checks may not always work. Still, measure often enough to reflect real day-to-day work. Finally, use the right tools. As a result, you gain accuracy and speed.

FAQ about the service level call center

What is a good call center service level?

The classic target is 80/20. In other words, agents answer 80% of calls within 20 seconds. Still, some teams aim higher, such as 90/10.

How do you calculate service level?

The simplest way divides calls answered within the threshold by total calls answered, then times 100%. However, other formulas add abandoned calls. So the right choice depends on your goals.

What affects call center service level?

Staffing, speed of answer, and handle time all play a part. In addition, abandon rate and occupancy shape the final number.

Why does service level matter?

It links straight to customer satisfaction. Fast, steady answers keep people happy. As a result, they stay loyal and come back.

What tools improve service level?

An ACD routes calls fast. Meanwhile, a WFM tool plans staffing, and time tracking shows how agents spend their day. Together, they lift service level.

Key takeaways

• A service level call center metric shows how fast and how well agents answer calls.
• The 80/20 rule is a common benchmark, but targets vary by business.
• Speed of answer, handle time, abandon rate, and occupancy all shape the score.
• The right software and clear KPI goals help teams hit their targets.
• Strong service level drives higher satisfaction and better retention.

To scale a support team the smart way, many firms explore call center services built around these metrics.
