What is Average wait time?

Why is average wait time important for customer experience?

Waiting is one of the most visible forms of customer effort, and long or unpredictable delays increase abandonment and dissatisfaction.

• Shows how quickly customers reach service.
• Highlights queues or periods with insufficient capacity.
• Connects operational delay with abandonment behavior.
• Supports decisions about self-service and callback options.

How Average wait time works

• Timestamp when an eligible contact enters a queue and when service begins or the customer abandons.
• Subtract periods that the metric definition explicitly excludes, such as scheduled callbacks, only if those rules are disclosed.
• Sum eligible waiting time and divide by the corresponding answered or offered contacts.
• Report distributions and abandonment alongside the average because a single mean hides long-tail waits.

Average wait time in action

A contact center reports a 70-second average wait, but its p95 is nine minutes and many callers abandon after two minutes. Adding percentile and abandonment data reveals a serious experience problem that the average alone concealed.

How Average wait time is measured or evaluated

Use a stable formula and representative production data. Track the following measures together:

• average wait time: total eligible queue time divided by the defined contact count
• median, p90, and p95 wait time
• abandonment rate and time to abandonment
• service level: share answered within a target threshold
• callback acceptance and completion rate

Limitations, risks, and common failure modes

• Mixing answered-only and all-offered denominators changes the result.
• Callbacks can make waits look shorter if their delay is excluded without explanation.
• The average can improve while a smaller group experiences extreme waits.
• Transfers between queues may reset clocks and erase customer effort.

Use average wait time as one view of queue performance. Percentiles, abandonment, callbacks, and end-to-end customer delay complete the picture.

Average wait time vs. average speed of answer

Average wait time may include broader queue-delay definitions. Average speed of answer usually measures the time answered contacts wait before an agent answers, often excluding abandoned calls.

What teams should consider when using or implementing Average wait time

• Document when the clock starts, stops, pauses, and resets.
• Keep answered, abandoned, transferred, and callback populations visible.
• Set service targets by urgency and customer promise.
• Measure end-to-end delay across queue transfers.
• Review staffing forecasts against the full wait-time distribution.
