Use the standard formula: active handle time plus ACW divided by resolved tickets. Then split where time is spent: conversation, hold, writing, documentation, or handoff. That keeps AHT from becoming a speed target without quality control.
Start with the full AHT formula
Use active handle time plus after-call work divided by resolved tickets. This keeps documentation, wrap-up, and follow-up work inside the calculation.
- Split conversation time, hold time, and ACW when possible.
- Compare the same channels and case types.
- Use the same time window as your staffing data.
Use the example calculation as a sanity check
With 5,400 active minutes, 900 ACW minutes, and 700 resolved tickets, the output is 9.0 minutes AHT. If your result looks extreme, check scope before changing targets.
- Make sure ACW is not counted twice.
- Keep escalated tickets separate.
- Label peak weeks before comparing them with normal weeks.
Read benchmarks by channel, not as one hard rule
A lower AHT is only healthy when first contact resolution, reopen rate, and CSAT stay stable. Use benchmarks as diagnostic signals, not agent pressure.
- Order-status questions should not be compared with complaints.
- Chat, email, and voice each need their own baseline.
- Tie AHT decisions to quality metrics.
Avoid the classic AHT math mistake
Do not average separate AHT averages across agents or queues. Add all handle time and ACW first, then divide by the total resolved tickets. Otherwise a small queue gets the same weight as your largest support flow.
- Use weighted totals when you combine queues.
- Keep admin tasks separate if they are not customer interactions.
- Label escalations so they do not distort normal AHT.
Turn AHT into capacity impact
The calculator shows how many hours a 10% lower AHT would free in the ticket set you entered. Use that to choose between AI draft replies, better routing, or staffing changes.
- High ACW: improve draft replies and documentation.
- High active time: improve knowledge, context, and macros.
- Low buffer: check staffing and occupancy.
