What it means
A contact centre's largest cost is people, and the number of people it needs depends on how many contacts arrive and how long each one takes. Average handle time is the second of those.
If a centre receives 10,000 calls a day and each takes an average of six minutes including wrap-up, it needs 1,000 agent-hours of handling time a day; at five minutes, 833. The difference across a year is many thousands of hours and several full-time positions.
That arithmetic is why AHT is watched so closely, and why it is often the first target when a centre's costs are under pressure. The components of AHT each have their own drivers.
Talk time depends on the complexity of the enquiry, the agent's skill and the quality of the systems and information available to them. Hold time depends on how often agents need to consult someone or look something up.
Wrap-up time depends on the logging and follow-up the process demands and how well the systems support it. Reducing AHT sustainably means improving those drivers: better knowledge bases, simpler systems, clearer processes, more authority for agents to resolve issues, fewer transfers.
Reducing it by pressuring agents to end calls faster produces the opposite: unresolved issues, repeat calls, escalations and lower satisfaction. For that reason AHT is read alongside first contact resolution (the share of issues resolved without a repeat contact), customer satisfaction scores and repeat contact rates.
A centre that cuts AHT by 10% while first contact resolution falls from 80% to 70% has not become more efficient; it has moved the work to a second call. The best-run centres treat AHT as an output of good process design rather than a target for agents, and they use it to plan staffing rather than to police individuals.
AHT varies by contact type, channel and customer segment, so the average across a whole centre hides more than it shows. Analysis by call reason and by agent identifies the handful of processes that consume most of the time and the training gaps that lengthen calls for some agents but not others.
In practice
Real-world examples.
Example
A bank's call centre reports AHT of 4.5 minutes for balance enquiries and 14 minutes for disputed transactions, and staffs each queue separately.
Example
An online retailer's chat support runs an AHT of 9 minutes because agents handle two or three chats at once; it measures concurrent handling capacity rather than raw AHT.
Example
A software company's technical support team has an AHT of 22 minutes and a first contact resolution of 91%, and its management resists pressure to cut the time because the resolution rate is what customers value.
Think of it
“AHT shows how long customer service interactions typically take-the time cost per customer contact.
Formula
Calculation
Average Handle Time = (Total Talk Time + Total Hold Time + Total Wrap-up Time) / Number of Contacts Handled
Agents Required (simplified) = (Contacts per period x AHT) / (Available agent time per period x Target occupancy)
Worked example. A telecoms support centre handled 24,000 calls in a week. Total talk time was 108,000 minutes, total hold time 9,600 minutes, and total wrap-up time 26,400 minutes.
- AHT = (108,000 + 9,600 + 26,400) / 24,000 = 144,000 / 24,000 = 6.0 minutes
Staffing: agents work 37.5 hours a week, of which about 30 hours (1,800 minutes) are available for handling after breaks, training and meetings. The centre targets 85% occupancy (the share of available time actually spent handling, the rest being brief idle periods between calls that are needed to answer promptly).
- Handling minutes required = 24,000 x 6.0 = 144,000
- Agents required = 144,000 / (1,800 x 85%) = 144,000 / 1,530 = 94 agents
If AHT falls to 5.4 minutes through better systems (a 10% reduction), handling minutes fall to 129,600 and agents required to 85, a saving of 9 positions, or about $400,000 a year at a fully loaded cost of $45,000 each.
Quality check: the centre's first contact resolution is 78%, so about 5,280 of the 24,000 calls are repeat contacts about issues not resolved the first time. If improving resolution to 85% removed 1,680 repeat calls a week, the reduction in volume would save more agent time than a 10% AHT cut, and improve satisfaction at the same time. Wrap-up analysis shows agents spend 1.1 minutes per call on manual logging that a system change could automate, which would cut AHT to 4.9 minutes without shortening a single conversation.Case study
Seen in the real world.
An insurance company's claims call centre set agents a target AHT of 5 minutes, displayed on wallboards, with bonuses tied to it. AHT fell from 6.5 to 5.1 minutes within three months and the centre's manager was congratulated. Over the same period, repeat calls rose from 15% to 27% of volume, complaints doubled, and mystery shopping found agents ending calls before customers had finished asking questions and transferring anything complicated to a specialist queue with a 20-minute wait.
Total call volume rose 12%, more than cancelling the handling time saved, and the specialist team had to be expanded. A new head of operations removed AHT from the agent scorecard, replaced it with first contact resolution and customer satisfaction, and used AHT only for forecasting and for identifying process problems.
AHT drifted back up to 6.0 minutes; repeat calls fell to 11%; total handling time across the centre fell 8%; and the specialist queue shrank by half. The head of operations' summary was that the centre had been paying agents to make customers call twice.
Watch out
Common mistakes.
- Setting AHT as an agent target. It drives rushed calls, unresolved issues and repeat contacts.
- Reading the centre-wide average without breaking it down by contact type and agent. The average hides where the time goes.
- Measuring AHT without first contact resolution alongside it. Shorter calls that do not resolve the issue are more expensive, not less.
Questions
People also ask.
What is a good average handle time?
It depends entirely on the contact type: two to four minutes for simple transactions, ten to twenty for complex technical or claims work. Benchmark against similar queues, not across industries.
Should hold time and wrap-up time be included?
Yes. Both consume agent time and both are targets for process improvement. Excluding them understates the true cost per contact.
How can AHT be reduced without harming service?
By improving knowledge systems, simplifying screens and processes, giving agents authority to resolve issues, automating wrap-up logging and reducing transfers. Each shortens calls by removing waste rather than conversation.
