What is Call Abandonment Rate?


Understanding Call Abandonment Rate in Contact Centres

The Call Abandonment Rate is a crucial metric in contact centre operations that measures the percentage of incoming calls terminated by the caller before they reach an agent. This metric provides insights into customer patience, satisfaction, and potential issues within the call handling process.


How to Calculate Call Abandonment Rate

The Call Abandonment Rate is a crucial metric in contact centres that measures the percentage of incoming calls where the caller hangs up before speaking to an agent. This rate helps identify potential issues with long wait times, system inefficiencies, or inadequate staffing.

To calculate the Call Abandonment Rate, use the following formula:

For example, if a contact centre receives 1,000 calls in a day and 100 of those calls are abandoned before reaching an agent, the Call Abandonment Rate would be calculated as follows:

This metric is essential for understanding customer patience and satisfaction levels. A high abandonment rate often indicates that customers are experiencing long wait times, leading to frustration and hang-ups. By monitoring and managing this rate, contact centres can implement strategies to reduce wait times, such as optimizing staffing levels, improving call routing, or offering callback options.


Factors Contributing to High Call Abandonment Rates


  1. Long Wait Times: If customers have to wait too long before their calls are answered, they are more likely to hang up.
  2. Complicated IVR Systems: Complex or difficult-to-navigate interactive voice response (IVR) systems can frustrate callers, leading to higher abandonment rates.
  3. Insufficient Staffing: Inadequate staffing levels during peak times can result in longer wait times and increased call abandonment.
  4. Technical Issues: Problems with the phone system, such as dropped calls or poor call quality, can lead to higher abandonment rates.


Impact of High Call Abandonment Rates


  1. Customer Dissatisfaction: High abandonment rates often correlate with low customer satisfaction, as customers become frustrated when they cannot reach an agent.
  2. Lost Revenue Opportunities: Abandoned calls may represent missed sales opportunities or unresolved customer issues, which can impact revenue.
  3. Negative Brand Perception: Consistently high abandonment rates can damage a company’s reputation, as customers may perceive the business as inefficient or unresponsive.


Strategies to Reduce Call Abandonment Rates


  1. Optimize Staffing Levels: Ensure that there are enough agents available during peak times to handle the volume of incoming calls efficiently.
  2. Improve IVR Design: Simplify IVR menus to make them more user-friendly and reduce the time customers spend navigating options.
  3. Offer Callbacks: Provide an option for customers to request a callback instead of waiting on hold. This can significantly reduce frustration and abandonment.
  4. Enhance Training: Train agents to handle calls more efficiently, reducing the overall wait time for customers.
  5. Monitor and Analyze Data: Regularly monitor call abandonment metrics and analyze patterns to identify and address the root causes of high abandonment rates.



The Call Abandonment Rate is a vital performance indicator in contact centres, reflecting customer satisfaction and operational efficiency. By closely monitoring and addressing the factors that contribute to call abandonment, contact centres can improve customer experiences, reduce lost revenue opportunities, and enhance their overall service quality. Implementing strategies such as optimizing staffing levels, simplifying IVR systems, offering callbacks, and providing comprehensive agent training can significantly reduce call abandonment rates and contribute to the success of the contact centre.
