Do your agents spend too much time on each interaction? Or, on the contrary, do they rush through exchanges to get things done quickly?AHT is the indicator that allows you to find the right balance.

In this guide, learn everything there is to know about AHT: its definition, how to calculate and interpret it, and above all, how to optimize it without sacrificing quality.

AHT: definition

AHT (Average Handle Time) measures the average time an agent spends handling a customer interaction, from start to finish.

AHT generally includes:

  • Talk time: duration of direct communication with the customer
  • Hold time: moments when the customer is put on hold
  • After-call work (wrap-up): notes, CRM updates, etc.

This is a key indicator in contact centers because it directly impacts costs, processing capacity, and customer experience.

How to calculate AHT

The standard formula is:

AHT = (Talk time + Hold time + After-call time) / Number of interactions

Calculation example

In one day, an agent handles 40 calls with:

  • Total talk time: 200 minutes
  • Total waiting time: 20 minutes
  • Total post-call time: 60 minutes

AHT = (200 + 20 + 60) / 40 = 7 minutes

The average processing time is 7 minutes per call.

What is a good AHT?

The "ideal" AHT varies greatly depending on:

  • The sector: technical support vs. e-commerce vs. banking
  • The channel: phone vs. chat vs. email
  • Complexity: simple question vs. technical problem

Indicative benchmarks per channel:

CanalAverage AHTTypical range
Phone6 minutes4-10 min
Live chat8 minutes5-12 min
Email15 minutes10-25 min

Important: Do not blindly compare yourself to benchmarks. Your optimal AHT depends on your specific context.

AHT: friend or foe of quality?

This is THE question that divides customer service managers.

The risk of becoming obsessed with HAT

Pushing agents to reduce their AHT can have adverse effects:

  • Incomplete responses that generate reminders
  • Customers who feel like we want to get rid of them
  • Agent stress and turnover
  • Decrease in first contact resolution rate

AHT as an indicator, not as a target

AHT should be a diagnostic indicator, not a goal in itself. High AHT may indicate:

  • Training issues
  • Tools that are not very user-friendly
  • Overly complex processes
  • Lack of access to information

Rather than saying "reduce AHT," identify and address these root causes.

How to optimize AHT intelligently

1. Improve access to information

An agent who spends two minutes searching for information causes the AHT to skyrocket. Solutions:

  • Well-structured and easily searchable knowledge base
  • 360° customer view in CRM
  • Contextual response suggestions by AI

2. Automate post-call work

Wrap-up time can account for 20-30% of AHT. Reduce it with:

  • Automatic conversation summaries
  • Automatic ticket categorization
  • Pre-filled note templates

3. Train on conversational effectiveness

Simple techniques save time:

  • Ask the right questions from the outset
  • Structure the exchange (introduction, diagnosis, solution, confirmation)
  • Avoid digressions

4. Use AI as your co-pilot

AI can suggest responses in real time, reducing research and writing time.

That's what Klark does: provide agents with contextual and accurate answers instantly, reducing AHT while maintaining quality.

5. Identify outliers

Analyze interactions with abnormally high AHT:

  • Is this a specific type of request?
  • An agent who needs training?
  • A recurring problem that deserves a lasting solution?

AHT per channel: specific features

Phone

Telephone AHT is the most closely scrutinized because it is the most expensive channel. Focus on reducing hold time and wrap-up time.

Cat

AHT chat can be misleading because an agent often handles several conversations simultaneously. Also measure "concurrent chats" to get a realistic view.

Email

Email AHT is less critical because there is no real-time customer wait time. Focus instead on overall response time.

AHT and other KPIs: finding the right balance

AHT must be analyzed in parallel with other indicators:

KPIRelationship with the AHT
FCRPotential tension (speed vs. quality)
CSATAn AHT that is too short can have a negative impact.
Cost per contactDirect correlation
Occupancy rateHigh AHT reduces capacity

The goal is to find the "sweet spot": an optimized AHT that does not sacrifice customer satisfaction.

Mistakes to avoid

Mistake #1: Making it a rigid individual goal

"You have to be there in 5 minutes" creates stress and counterproductive behavior.

Mistake #2: Ignoring variability

The average AHT hides different realities. A simple question takes 2 minutes, a technical problem 15. That's normal.

Mistake #3: Not segmenting

Analyze AHT by request type, channel, and complexity level. The overall figure is not enough.

Mistake #4: Comparing different channels

A 15-minute email AHT is not comparable to a 6-minute phone AHT.

Frequently asked questions about AHT

What is a good AHT?

It depends! On the phone, 5-7 minutes is often a good target. But the important thing is the trend and the correlation with quality.

How can AHT be reduced without compromising quality?

Automate what can be automated (wrap-up, information search), train on efficiency, and use AI as an assistant.

Does AHT include the time the customer waits before being assisted?

No, "queue wait time" is a separate metric. AHT starts when the agent takes the interaction.

Should AHT be displayed to agents in real time?

Controversial. It can help raise awareness or create stress. Use with caution.

Conclusion: AHT for efficiency

AHT (Average Handle Time) is a powerful indicator, but one that must be used with caution. It should never become an end in itself at the expense of the customer experience.

The keys to optimized AHT:

  • Use it as a diagnostic indicator, not as a strict target.
  • Automate wrap-up and access to information
  • Train your agents in conversational effectiveness
  • Analyze by segment, not just overall
  • Always balance with quality (FCR, CSAT)
