What is Abandonment Rate?

Abandonment rate is the percentage of customers who leave a support queue (a chat or call) before ever connecting with an agent. It's a direct symptom of waiting too long: when the queue is slow, customers give up, and every abandoned contact is an unhappy customer and a lost chance to help.

What drives abandonment

Abandonment rises almost in lockstep with wait time. When average speed of answer climbs, more customers run out of patience and drop off. A high abandonment rate is rarely about the customers — it's a staffing or routing signal that people are waiting longer than they're willing to.

How to reduce abandonment

Cut the wait. Staff to your peak volume, route efficiently, and set expectations with queue position or callback options. The most effective lever is answering customers instantly with an AI agent on the front line — many never enter the human queue at all, so there's nothing to abandon.

Formula

Abandonment rate % = (Abandoned contacts ÷ Total inbound contacts) × 100

Example: If 40 of 1,000 chats are abandoned before an agent responds, abandonment rate = 40 ÷ 1,000 × 100 = 4%.

Questions about Abandonment Rate

What's a good abandonment rate?

Lower is better; many support teams aim to keep chat and call abandonment under ~5-8%. The right target depends on channel and staffing — track it against your average speed of answer.

How is abandonment rate related to ASA?

Closely. As average speed of answer rises, abandonment usually rises with it — customers abandon because they're waiting too long. Reducing wait time is the most reliable way to lower abandonment.

Related terms

Average Speed of Answer (ASA)

Average Speed of Answer (ASA) is the average time a customer waits in the queue before their contact is answered by an agent. Most common in chat and phone support, it measures queue wait specifically (not how long the whole interaction takes), and it's a direct driver of abandonment and satisfaction.

First Response Time (FRT)

First Response Time (FRT) is the average time between a customer reaching out and getting the first human (or AI) reply. It's a first impression metric: a fast first response reassures customers their issue is being handled, even if the full resolution takes longer. It strongly influences satisfaction.

Average Handle Time (AHT)

Average Handle Time (AHT) is the average total time it takes to handle a single customer contact — including talk or chat time, any hold time, and the after-contact work like notes and follow-ups. It's a core efficiency metric, but it should never be optimized at the expense of resolution quality.
