Containment rate is the share of customer interactions fully handled by an automated system, such as an IVR, chatbot, or artificial intelligence (AI) agent, without reaching a human agent. It is one of the most widely used measures of self-service performance in contact centers.
How It’s Calculated
Containment rate is the number of interactions that start and end in the automated channel, divided by the total number of interactions that enter it.
Definitions vary in practice. Some teams count an interaction as contained only if the customer does not call back within a set window. Others count any interaction that does not transfer to an agent, including customers who simply give up. The definition in use changes what the number means.
Containment vs Resolution
Containment measures where an interaction ended. Resolution measures whether the customer’s need was met. The two are often confused, and the gap between them matters.
- A customer who abandons a chatbot in frustration counts as contained, but their issue is not resolved.
- A customer who is contained today but calls back tomorrow often appears as two successful containments, while the actual experience was a failure.
- Optimizing for containment alone can push difficult interactions into cycles of self-service that would be better resolved by a person.
As a result, containment rate is best read alongside resolution, repeat-contact, and customer satisfaction measures rather than on its own.
