Call Center Staffing: How Many Agents Are Needed in a Contact Center?

Team Culture


In the ever-evolving landscape of customer service, contact centers play a pivotal role in establishing a strong connection between businesses and their clients. Call center staffing is a critical aspect of contact center management, as it directly impacts customer satisfaction, response times, and overall operational efficiency. Striking the right balance between having enough agents to handle incoming inquiries and not overstaffing is a challenge faced by many contact center managers. In this blog post, we will explore the factors to consider when determining how many agents you need in a contact center to ensure optimal performance and customer experience.

Understanding Call Center Workload

Before diving into staffing considerations, it is crucial to understand the workload that the contact center is expected to handle. Analyzing historical call data, peak hours, and anticipated call volumes for specific periods can help you predict incoming traffic patterns and fluctuations. This data-driven approach serves as a foundation for making informed decisions about staffing requirements.

Factors Influencing Staffing Levels

  1. Average Handle Time (AHT): AHT represents the average duration an agent spends on a single customer interaction, including talk time, hold time, and any after-call work. By analyzing AHT, you can determine how much time each agent dedicates to assisting customers, which aids in calculating the number of agents needed to meet service level objectives.
  2. Service Level Objectives (SLOs): SLOs define the percentage of calls that should be answered within a specific time frame, such as 80% of calls answered within 20 seconds. SLOs set the standard for contact center efficiency and directly influence the number of agents required during peak hours to meet these goals.
  3. Forecasted Call Volume: Accurate forecasting of call volumes during various periods (daily, weekly, and seasonally) is crucial for appropriate staffing. Advanced analytics tools can help predict call patterns based on historical data and external factors such as marketing campaigns or public events.
  4. Absenteeism and Attrition: It is essential to account for agent absenteeism and attrition rates when calculating staffing needs. Overstaffing to accommodate these fluctuations can be costly, so striking a balance is necessary.
  5. Skillset and Agent Specialization: Understanding agent skills and their expertise in handling specific types of inquiries can also impact staffing. Specialized agents may be needed for technical support or more complex issues.
  6. Multichannel Support: If your contact center handles interactions through various channels like phone calls, emails, live chat, or social media, you must factor in the appropriate staffing levels for each channel.

Effective Staffing Strategies

  1. Adopting Flexible Scheduling: Implementing flexible work schedules allows you to align agent availability with peak call times, minimizing understaffing and overstaffing issues.
  2. Implementing Real-time Monitoring: Utilize real-time monitoring and reporting tools to adjust staffing levels on the fly based on call volumes and other metrics.
  3. Cross-Training Agents: Cross-train agents to handle multiple tasks and channels to enhance versatility and optimize staffing across different channels.
  4. Outsourcing and Remote Work: Consider outsourcing certain functions or allowing agents to work remotely during peak times to manage high call volumes more efficiently.


In conclusion, determining the appropriate number of agents in a contact center requires a well-informed approach that considers call volume patterns, service level objectives, and agent efficiency. By leveraging historical data and using advanced analytics tools, contact center managers can optimize staffing levels, reduce costs, and ensure excellent customer experiences. Embracing flexibility, continuous monitoring, and agent training can further enhance the efficiency and effectiveness of the contact center, aligning it with the evolving needs of customers and the business. Ultimately, investing time and effort into strategic call center staffing will yield long-term benefits for both the organization and its valued customers.
