Average Handle Time
Definition
Average handle time (AHT) is the average total time an agent spends on one customer contact, from the moment it is answered to the end of the follow-up work after it. It includes talk time, hold time and after-call work, and it is the main input, with volume, for calculating how many agents a contact center needs.
Also called: AHT, Average handling time, Handle time
Formula
AHT = (Total talk time + Total hold time + Total after-call work time) ÷ Number of contacts handled
- Total talk time
- Time agents spent connected and speaking with customers, including any time in a conference or consult with the customer still on the line.
- Total hold time
- Time customers spent on hold during the call after it was answered. Queue wait before the answer is not included.
- Total after-call work time
- Wrap-up time after the customer disconnects: notes, dispositions, follow-up tasks. Also called ACW or wrap time.
- Number of contacts handled
- Calls (or chats, emails) answered and completed by agents in the period. Abandoned calls are excluded.
Worked example
On Tuesday a team of 12 agents handles 1,050 calls. Total talk time is 4,725 minutes, hold time 630 minutes and after-call work 945 minutes. AHT = (4,725 + 630 + 945) ÷ 1,050 = 6,300 ÷ 1,050 = 6.0 minutes, or 360 seconds. Hold makes up 10% and after-call work 15% of the total, which tells the team leader where to look first.
What AHT includes and why each part matters
AHT is a sum of three parts, and the fix depends on which part is long.
- Talk time is driven by call complexity, agent knowledge and how well the agent controls the conversation.
- Hold time usually means the agent had to look something up or ask someone. High hold points to knowledge gaps, slow systems or a hard-to-search knowledge base. The average hold time page covers it on its own.
- [After-call work](/glossary/after-call-work/) is notes, dispositions and follow-up tasks. Long wrap time often comes from clunky CRM screens or policies requiring duplicate notes.
Always report AHT with its components. An AHT of 360 seconds could be 300 talk, 20 hold and 40 wrap, or 220 talk, 80 hold and 60 wrap. Those are two different problems.
Typical average handle times
AHT varies so much by work type that a single industry average is close to useless. Ranges commonly seen on voice:
- Simple customer service (order status, address changes, basic account questions): about 3 to 5 minutes.
- Billing and account management: about 5 to 8 minutes.
- Financial services and insurance: about 6 to 10 minutes.
- Technical support: about 8 to 15 minutes or more.
- Healthcare member services: often 6 to 10 minutes.
Chat AHT per conversation is usually longer than voice, but agents often run two or three chats at once, so cost per contact can still be lower. Email is typically measured in minutes of handling, not elapsed time.
Your own history by call type, channel and tenure band is the benchmark that matters.
How AHT drives staffing and cost
Workload is volume times handle time. If a center receives 1,000 calls an hour at 360 seconds AHT, that is 360,000 seconds, or 100 hours of work in that hour, before accounting for queueing and shrinkage. An Erlang C calculation then turns that workload into the agent count needed to hit the service level target.
That makes AHT one of the most expensive numbers in the building. A 30-second increase on 1,000 calls an hour adds about 8.3 hours of work per hour, which can mean ten or more extra agents scheduled once shrinkage is included. This is why new-hire classes affect planning so much: an agent in nesting with an AHT 40% above the floor average is a fraction of a full agent in staffing terms.
How to reduce AHT without hurting quality
Cutting AHT by telling agents to go faster is the oldest mistake in the contact center. It moves the time somewhere else, usually into repeat calls. Remove the reasons calls are long instead.
- Break AHT down by call type and component. Find the three call types with the most total handle time and the biggest gap between top and average agents.
- Learn from the fastest good agents. Listen to agents with low AHT and high quality and FCR. They usually have a better navigation path, a sharper discovery question or a clearer explanation. Turn it into training.
- Fix the knowledge base. If agents put customers on hold to search, the knowledge base is the problem. Structure articles around customer questions, not policies.
- Reduce system friction. Single sign-on, fewer screens, pre-populated customer data and auto-generated call summaries cut wrap time directly.
- Route by skill. Calls that reach the right agent the first time avoid transfers and long discovery.
- Coach new agents on call control. Most of the AHT gap for new hires is hesitation and searching. Targeted practice on the top call types in training and nesting closes it faster.
- Remove calls that should not exist. Self-service for simple requests lowers volume but raises AHT on the remaining complex calls. That is a good trade; expect it and explain it.
Common AHT mistakes
- Hard AHT targets for individual agents without quality and resolution alongside. Agents learn to transfer, rush or even disconnect difficult calls.
- Comparing AHT across different call mixes. The agent on the billing queue and the agent on technical support should not share a target.
- Ignoring tenure. New agents will run higher. Set ramped targets during the first months.
- Excluding after-call work to make the number look better. It is real agent time and must be in the staffing math.
- Celebrating AHT drops after self-service launches when they are actually rises. If simple calls move to self-service, the remaining calls are harder and AHT should rise.
Track AHT with the rest of your call center KPIs, always next to first call resolution and quality.
Frequently asked questions
What is the AHT formula?
AHT = (total talk time + total hold time + total after-call work) ÷ number of contacts handled. Calculate it for a period, such as an interval, a day or a month, and by call type for useful comparisons.
What is a good average handle time?
It depends on the work. Simple customer service calls often average 3 to 5 minutes, billing 5 to 8, and technical support 8 to 15 or more. Judge AHT against your own call types and alongside resolution and quality.
How can I reduce AHT in a call center?
Break AHT into talk, hold and wrap by call type, copy the habits of agents who are fast and accurate, improve the knowledge base and systems, route calls to the right skill and coach new agents on call control. Avoid pushing agents to simply go faster.
Does AHT include hold time?
Yes. Standard AHT includes hold time during the call, but not the time a caller waits in queue before an agent answers.
What is the difference between AHT and talk time?
Talk time is only the time spent speaking with the customer. AHT adds hold time and after-call work, so it reflects the full agent time a contact consumes.
Why does AHT matter for staffing?
Required staff depends on contact volume multiplied by handle time. Even small AHT changes on high volume add or remove many hours of work and change how many agents you must schedule.
