Average Handle Time (AHT)
Definition
Average Handle Time (AHT)
Average handle time (AHT) measures the mean duration of a customer contact. It pools talk time, hold time, and after-call work, then divides by the total number of contacts handled in a period. A healthy AHT balances speed with resolution quality; cutting it recklessly hurts customer experience.
Contact center leaders track AHT weekly, monthly, and quarterly. It surfaces training gaps, staffing pinch points, and process friction that pad every interaction.
The metric predates omnichannel support. When phones were the only inbound door, AHT was the shift manager’s compass. Today chat, email, and social sit alongside it — reported next to first-contact resolution (FCR), CSAT, and average speed of answer.
Key takeaways
- AHT = (total talk + total hold + after-call work) ÷ total contacts handled.
- Global voice benchmarks land near six minutes; banking and technical support run 20–40% longer (Talkdesk, 2024).
- Cutting AHT without matching investment in agent training and knowledge bases erodes first-contact resolution.
- Modern AHT reporting spans voice, chat, and email; phone-only dashboards understate real handle load.
- After-call work alone can eat 15–20% of total AHT when CRM forms lag (Cornell ILR, 2023).
How it works
Average handle time measures the full length of a customer contact, then averages that figure across a period. The formula pools three inputs — talk, hold, and after-call work — and divides by contacts handled. Read the trend, not the raw number.
The formula breaks down cleanly:
AHT = (total talk time + total hold time + after-call work) ÷ total contacts
Each input carries a different pressure point:
- Talk time: the live conversation between agent and caller.
- Hold time: any period the caller sits on mute while the agent researches or transfers.
- After-call work (ACW): logging notes, updating the CRM, tagging the disposition code.
- Total contacts: voice calls, chats, or emails counted by your workforce management (WFM) tool.
Global benchmarks put voice AHT near six minutes, but the range is wide. Talkdesk’s 2024 CX report clocked technical support at 8–12 minutes while retail order queries cleared in under three. Cornell University ILR research on call center productivity notes that ACW alone can consume 15–20% of total handle time when knowledge bases lag.
Read AHT honestly by splitting it by channel and complaint type. A five-minute average across voice and email is meaningless if voice sits at eight and email at two. Skills-based automatic call distribution (ACD) and layered interactive voice response (IVR) menus cut wasted transfers, which trims hold time without pressuring agents to rush.
| Channel | Typical AHT (2024) | Main driver |
|---|---|---|
| Voice, retail | 2:30–3:30 | CRM screen-pop, tight script |
| Voice, technical | 8:00–12:00 | Diagnosis, escalation |
| Live chat | 8:00–15:00 | Concurrent conversations |
| 3:00–6:00 | Drafting and review only |
Examples
AHT plays out differently across industries. A bank fielding fraud disputes needs longer conversations to verify identity and resolve chargebacks. An e-commerce shop taking order-status calls can trim AHT under three minutes with the right CRM screen-pop.
Retail account, Manila (2024). A business process outsourcing (BPO) partner serving a US e-commerce retailer cut AHT from 5:40 to 4:10 after deploying skills-based routing and a rebuilt agent script. First-contact resolution held at 82% through the quarter.
Healthcare payer, Cebu. An insurance BPO deliberately raised AHT from 7:20 to 8:50 through 2023 after adding a mandatory eligibility recheck. Complaint call volume fell 30% because fewer members had to call back.
Telecom, US. According to Zendesk’s 2024 CX Trends benchmark, tier-2 technical support handled inside US telecoms averages roughly 10 minutes per contact — against 4 minutes on tier-1 activation calls. The split lets workforce-management teams staff each tier on separate curves.
SaaS live chat. The same 2024 benchmark put chat handle time between 8 and 15 minutes per resolved case, because agents typically juggle two to three concurrent chats. Voice AHT on the same tickets averaged 4:30.
Call parking is another workflow lever some centers use to keep queues moving while an agent researches. Held calls resume with any teammate on the floor rather than waiting for the original agent.

FAQ
What is a good average handle time?
Six minutes is the loose global benchmark for voice contacts, per Talkdesk’s 2024 industry report. But “good” depends on channel and complexity. Technical support, banking, and insurance run 8 to 12 minutes; retail order queries clear in under three.
Does lower AHT always mean better service?
No. Cutting AHT by rushing calls typically drops first-contact resolution and CSAT within a quarter. A stable AHT paired with a rising FCR is the healthier pattern; that signals agents are resolving more, not talking less.
How is AHT different from average speed of answer (ASA)?
ASA measures the caller’s wait before an agent picks up. AHT measures what happens after. Both feed service-level agreements but tackle different bottlenecks — ASA is a staffing problem, AHT is a training-plus-tooling problem.
What counts as after-call work?
Everything the agent does between hanging up and taking the next contact: writing case notes, updating the CRM, tagging the disposition code, sending a follow-up email. Poorly designed forms are the single biggest ACW inflator.
How do you calculate AHT for chat and email?
Same formula, different clock. For chat, handle time starts at the first agent message and ends when the case closes; ACW covers any post-chat notes. Email AHT typically excludes queue wait and only counts active drafting time.
Which tools help contact centers manage AHT?
Modern WFM suites, ACD platforms, and CRM screen-pops all shape AHT. Speech analytics and post-call automation cut ACW; skills-based routing trims hold time. Most centers layer three or four tools rather than betting on a single vendor.
