Cost Per Call: The Contact Centre KPI That Drives ROI in 2026
Discover how to effectively analyze and reduce your contact centre's cost per call (CPC) while improving service quality using AI-powered hybrid models.

In today's competitive business landscape, contact centres face immense pressure to deliver exceptional customer experiences while operating at peak efficiency. This balancing act poses challenges, yet it's manageable with a strategic approach. The cornerstone of this strategy involves understanding and optimizing operational costs, with one of the most critical yet often misunderstood key performance indicators (KPIs) being the cost per call (CPC).
This article explores the importance of CPC, details how to accurately calculate it, and discusses how this metric can be leveraged to enhance your contact centre's productivity and efficiency. Furthermore, we will investigate how modern solutions, particularly AI-powered hybrid models, can significantly reduce CPC without sacrificing service quality.
What is Cost Per Call (CPC) and Why Does It Matter?
Cost per call is a metric that quantifies the total expense incurred for each call handled by a contact centre. As a leading customer experience platform, Zendesk defines CPC as a measure of "the average cost of each call handled by a call center." This KPI holds paramount importance because it offers a clear perspective on the cost-effectiveness of contact centre operations and serves as a primary driver for strategic resource allocation.
Similarly, Genesys, a global leader in cloud customer experience and contact centre solutions, emphasizes that the CPC metric provides a "critical view into operational effectiveness." By tracking CPC, organizations can establish performance targets, identify overspending, and make informed decisions that positively impact their bottom line.
The True Cost of a Call: More Than Just Salaries
Calculating your CPC is more nuanced than merely dividing total agent salaries by the number of calls. An accurate calculation must encompass a variety of direct, indirect, and variable costs. Voiso, a provider of contact center software, provides a comprehensive breakdown of these cost components:
Cost Category | Cost Drivers | Examples |
Direct Costs | Expenses directly tied to interaction handling | Agent salaries and wages, VoIP/telephony fees, software licenses (CRM, dialer) |
Indirect Costs | Expenses related to support and operational infrastructure | Supervisor and QA team salaries, training and onboarding, office rent and utilities, hardware |
Variable Costs | Expenses that fluctuate with call volume, seasonality, or other factors | Temporary or seasonal staff, multilingual support, compliance and legal oversight |
Taking all these factors into account leads to a more precise and insightful CPC calculation.
Beyond the Basics: A More Granular Approach to Cost Calculation
While calculating an average CPC is a useful starting point, a thorough analysis necessitates a more granular approach. Not all calls possess the same cost profile; a simple password reset incurs different costs than complex technical support inquiries. Consequently, segmenting your CPC by various factors such as:
- Call Type (e.g., sales, support, billing)
- Channel (e.g., voice, chat, email)
- Agent Tier (e.g., junior vs. senior agent)
- Customer Value (e.g., standard vs. VIP customer)
This detailed approach provides a deeper understanding of your cost drivers, enabling more targeted improvements. Furthermore, the industry is moving toward a more outcome-focused "cost per resolution" metric, which considers the complexity and value of each interaction rather than merely the duration.
Industry Benchmarks: How Do You Stack Up?
To assess performance effectively, comparing your CPC to industry benchmarks is invaluable. The 2025 US Contact Center Decision-Makers' Guide from ContactBabel, a leading analyst firm in the contact centre sector, states that the average cost of an inbound call is $7.16. This figure highlights a stark contrast with other channels, revealing that calls typically cost 18% more than emails and 42% more than web chat interactions.
Such benchmarks underscore the necessity of optimizing your voice channel and investigating more cost-efficient alternatives for handling routine inquiries.
How to Reduce Your Cost Per Call (Without Sacrificing Quality)
Reducing CPC doesn't require sacrificing quality or cutting corners. Here are several strategic methods to lower costs while enhancing service:
- Invest in Agent Training: Investing in comprehensive agent training programs translates to increased efficiency and effectiveness, resulting in shorter call durations and greater first-call resolution rates.
- Optimize Your IVR: Crafting a well-designed Interactive Voice Response (IVR) system aids in directing calls to the appropriate agent or department, thereby reducing unnecessary transfers and boosting overall operational efficiency.
- Embrace a Remote or Hybrid Work Model: As noted by Zendesk, remote work can yield significant savings associated with office space and utilities. Exploring the return on investment (ROI) of a hybrid receptionist model that blends AI call handling with live receptionists may further enhance overall efficiency, as discussed here.
- Leverage AI and Automation: The most profound cost savings often stem from implementing AI-powered solutions capable of managing high volumes of routine inquiries, thus liberating human agents for more intricate and high-value interactions.
The Power of AI in Optimizing Contact Centre Costs
AI-driven virtual agents and hybrid contact centre models are spearheading a transformational movement within the industry. Companies like Norango.ai are at the forefront of this innovation, seamlessly combining AI capabilities with human expertise. Their AI receptionists are equipped to manage a significant volume of calls around the clock, addressing inquiries, booking appointments, and capturing leads—all at a fraction of the cost associated with human agents. This hybrid model showcases substantial cost-saving benefits, further elaborated on here.
This hybrid approach maximizes efficiency and cost-effectiveness for routine tasks, while simultaneously leveraging the empathy and problem-solving abilities of human agents for more complex challenges.

Frequently asked questions
What is meant by Cost Per Call (CPC) in a contact centre?
Cost Per Call (CPC) is a metric that quantifies the total expense incurred for each call managed by a contact centre. It includes various cost components associated with direct, indirect, and variable expenses, providing a clear perspective on the cost-effectiveness of operations. By tracking CPC, businesses can set performance objectives, identify inefficiencies, and make informed decisions aimed at enhancing their profitability.
How can companies accurately calculate their Cost Per Call?
To calculate Cost Per Call accurately, companies must consider a range of expenses beyond just agent salaries. This includes direct costs related to call handling, indirect costs linked to operational infrastructure, and variable costs that vary with call volume. A comprehensive approach to cost categorisation allows for a more precise calculation and ultimately a better understanding of how to optimise costs.
Why should companies segment their Cost Per Call analysis?
Segmentation of Cost Per Call analysis is important because not all calls have the same cost attributes. By differentiating costs based on call type, channel, agent tier, and customer value, companies can uncover specific cost drivers. This detailed insight enables more targeted improvements, such as optimising processes for different customer interactions and improving overall efficiency.
What strategies can contact centres implement to reduce their Cost Per Call without impacting service quality?
Contact centres can implement several strategies to lower Cost Per Call while preserving service quality. Investment in agent training enhances efficiency, leading to swifter resolve times.
