What Is Average Handle Time (AHT)?
Published
Average handle time, almost always shortened to AHT, is one of the most widely used measures in call centers. It shows how long, on average, it takes to deal with a customer contact from start to finish. AHT is used for planning, performance reviews, and comparing teams. It's also one of the most misunderstood metrics, because a lower number isn't always a better one.
The Definition
Average handle time is the average total time spent on each call, including:
- Talk time, the time spent speaking with the customer.
- Hold time, the time the customer spends on hold during the call.
- After-call work, the time spent completing tasks after the call ends, such as writing notes or updating records.
How to Calculate AHT
The standard formula is:
AHT = (Total talk time + Total hold time + Total after-call work) ÷ Number of calls handled
For example, imagine an agent handles 40 calls in a day, with:
- 160 minutes of talk time
- 20 minutes of hold time
- 60 minutes of after-call work
Total handling time is 240 minutes. Divided by 40 calls, the AHT is 6 minutes per call.
AHT can be calculated for an individual, a team, a type of call, or the whole operation, and over any period, such as a day, week, or month.
AHT and Talk Time Aren't the Same
People sometimes use AHT and talk time interchangeably, but they're different. Talk time covers only the conversation. AHT includes holds and after-call work too. An agent with short talk time but long after-call work may have a higher AHT than a colleague who talks longer but completes notes quickly.
Looking at each part separately often reveals more than AHT alone. For example, high hold time might point to difficulty finding information, while high after-call work might point to complicated systems.
Why AHT Matters
Planning staff numbers
AHT is essential for workforce planning. To work out how many people are needed, planners combine expected call volume with AHT. If AHT rises, more people are needed to handle the same number of calls.
Understanding workload
AHT shows how much effort different types of calls require. Billing questions might take four minutes on average, while technical issues might take twelve.
Spotting problems
Sudden changes in AHT can signal issues, such as a confusing new product, a system slowing down, or a process that's become more complicated.
Coaching
Comparing an individual's AHT with similar colleagues can help identify where coaching might help, such as using systems more efficiently or structuring calls more clearly.
What Affects AHT
Many factors influence handle time, including:
- Call complexity. Some issues simply take longer to solve.
- Experience. New agents usually take longer while they learn.
- Systems. Slow or difficult systems add time.
- Knowledge resources. Clear, easy-to-search information shortens calls.
- Processes. Lengthy verification steps or approvals increase handle time.
- Customer needs. Some customers need more explanation or reassurance.
- Call mix. If AI or self-service handles simpler requests, the calls left for people are often harder, which can raise AHT.
The Problem With Chasing a Lower AHT
Because shorter calls mean fewer staff are needed, it can be tempting to push AHT down as far as possible. But this can backfire.
Rushed calls. Agents under pressure to keep calls short may cut explanations short or skip steps.
Unresolved issues. Customers whose problems aren't fully solved call back, which increases total workload and frustrates customers.
Poor customer experience. Customers can tell when they're being hurried.
Gaming. Agents may transfer difficult calls, end calls prematurely, or delay notes until later to keep their AHT low.
Stress. Strict AHT targets can add pressure and contribute to burnout.
A slightly longer call that fully solves the problem is almost always better than a short call that leads to another call later.
Using AHT Wisely
AHT is most useful when it's:
- Read alongside other measures, such as first call resolution, quality scores, and customer satisfaction.
- Compared fairly, looking at similar call types and experience levels.
- Used to understand, not just judge, by listening to calls to see why handle times differ.
- Reduced in the right ways, by improving systems, knowledge, processes, and training, rather than pressuring people to talk faster.
Healthy Ways to Improve AHT
- Make information easier to find, so agents spend less time searching.
- Simplify processes and remove unnecessary steps.
- Improve systems that are slow or require repetitive data entry.
- Use AI tools to write call summaries, reducing after-call work.
- Train agents on common call types and efficient call structure.
- Route callers to the right person first time, avoiding transfers.
A Measure of Effort, Not Success
Average handle time tells a business how long calls take. It doesn't tell it whether those calls went well. Used thoughtfully, AHT is invaluable for planning and spotting problems. Used as a target on its own, it can push people toward quick calls rather than good ones. The best call centers treat AHT as one piece of the picture, always read alongside whether customers actually got the help they needed.
