Average Handle Time is the mean total time an agent is occupied by a single contact, measured from the moment it connects until they are ready to take the next one. It is the sum of talk time, hold time and after-call work (ACW), divided by the number of contacts handled.
AHT is deliberately broader than talk time. A contact that involves two minutes of conversation, one minute on hold while the agent checks a back-office system, and 45 seconds of wrap-up notes has an AHT of 3 minutes 45 seconds, not two minutes. Any component you leave out understates your workload and understaffs your operation.
It should always be calculated on contacts handled rather than contacts offered. Abandoned contacts consume no handle time, so including them in the denominator quietly deflates the figure.
Why it matters
- AHT and volume are the two inputs that produce workload, so an error here scales directly into your headcount requirement and your budget.
- The breakdown matters more than the total: high talk points at complexity, high hold at systems and knowledge, high ACW at process and tooling. Each is fixed by a different team.
- Using AHT as an individual agent target tends to backfire, it encourages rushed calls, transfers and repeat contacts, damaging first contact resolution.
