What is call abandonment rate?

Call abandonment rate is the percentage of incoming calls where the caller hangs up before reaching anyone, while ringing, during a phone menu, or on hold. It is calculated by dividing abandoned calls by total incoming calls and multiplying by 100. A high rate usually means callers wait too long or can’t find the right option.

How to measure call abandonment

Most phone systems report abandoned calls directly. Many teams exclude very short abandons, a few seconds, because those are often misdials. Compare the rate by hour of day: abandonment usually clusters at peaks, such as lunch, Monday mornings, or right after a promotion.

The causes are almost always time and friction: long hold queues, menus that don’t fit the caller’s problem, and calls ringing with nobody free. The fixes follow from that: shorter menus or none, a sensible ring time, and an overflow destination that answers instead of queuing.

Illustrative example

Example: a restaurant on Friday evening

A busy restaurant puts callers on hold during the Friday dinner rush while staff seat guests. Its phone report shows many calls abandoned between 6 and 8 p.m., mostly reservation and takeout-hours questions. Sending unanswered calls to an AI assistant after a short ring turns those hold queues into answered calls and booked tables. This scenario is illustrative.

How InsertChat removes hold queues

InsertChat’s AI receptionist answers every call it receives without a hold queue or a keypad menu, because each call gets its own conversation. Use “AI when unanswered” to ring your team for 5 to 60 seconds first, then let the assistant answer.

Calls that end before a conversation starts show up as missed calls in the Today view. See the restaurant setup.

Call abandonment rate: common questions

Plain answers for small businesses

Divide abandoned calls by total incoming calls for the period and multiply by 100. State whether you exclude very short abandons, so the number is comparable over time.

Definitions vary. Many teams count a caller who hangs up at the voicemail greeting as abandoned, since they never reached anyone and left nothing.
