Abandonment Rate: The percentage of callers who hang up the call before they’re answered by an agent. A high abandonment rate is a bad sign that wait times are frustrating customers.

Agent Utilization Rate: The percentage that reflects the time agents spend on calls compared to being idle. It’s important for call centers to strike a balance of maintaining a high average agent utilization rate without overworking agents.

Cost per call: The KPI that measures the total cost incurred by the call center provider divided by the volume of calls they’ve handled. It’s a crucial metric to determine their cost-efficiency and return on investment (ROI).

Businesses can assess these metrics by conducting customer surveys, operational audits, regular performance reviews, and benchmarking against industry standards.
