Abandonment Rate

Definição

Abandonment rate is the percentage of customers who leave a support queue — hanging up a call or closing a chat — before ever reaching an agent.

How to calculate it

The formula is: (abandoned contacts ÷ total contacts offered) × 100. If 2,000 people entered the queue and 200 left before connecting, the abandonment rate is 10%.

Many teams exclude very short abandons (customers who drop within a few seconds, often misdials) to avoid overstating the problem. Abandonment tracks closely with wait time — the longer the queue, the more people give up.

Why it matters

Abandonment is a direct symptom of understaffing or long waits, and every abandoned contact is a customer who didn't get help — and may just contact again later, inflating volume. Reducing wait time through better staffing, callbacks, or deflecting routine contacts to automation is the usual fix.

Perguntas frequentes

What is a good abandonment rate?

Many contact centers aim to keep it under 5–8%, though acceptable levels depend on channel and customer expectations. The trend matters more than the absolute number — a rising rate signals queues are getting too long.

What causes a high abandonment rate?

Usually long wait times from understaffing or volume spikes. Customers leave the queue rather than keep waiting, so it moves in step with average speed of answer and service level.
