Call center cost per call represents the cost incurred in conducting operations for a single customer call in a particular period of time. The formula used in the computation is dividing the call center cost by the number of calls handled.
The metric allows companies to determine the cost incurred in hiring personnel, use of technology, efficiency, and outsourcing. Nevertheless, the cost per call being low does not mean it is advantageous. Reducing costs without considering accuracy, client satisfaction, and employee satisfaction increases repeat calls.
What Is Call Center Cost per Call?
The cost per call is a financial performance measure that highlights the total amount of money that is spent by a firm to process one call.
Costs may include salaries of employees, benefits, software, telecoms systems, training, management, quality control, facilities, and many others.
The measurement can be applied for:
- An entire call center
- A specific client or campaign
- Inbound customer support
- Outbound sales calls
- Technical support
- A particular department
- A selected reporting period
Businesses should define which expenses and call types are included before comparing results. Otherwise, two teams may report different costs even when their operations are similar.
How Do You Calculate Cost per Call?
The basic cost-per-call formula is:
Cost per Call = Total Call Center Operating Costs ÷ Total Calls Handled
For example, suppose a call center spends $60,000 during a month and handles 20,000 calls.
Cost per Call = $60,000 ÷ 20,000 = $3
The average cost is therefore $3 per handled call.
Businesses should use completed or meaningfully handled calls rather than every dial attempt. Abandoned inbound calls, unanswered outbound calls, and automated interactions may need separate reporting.
The original Dazonn Assist guide also presents cost per call as a way to understand operational spending and identify opportunities for greater efficiency.
Which Costs Should Be Included?
An accurate calculation should include direct and indirect expenses connected to call handling.
| Cost Category | Common Examples |
|---|---|
| Employee costs | Salaries, incentives, benefits and overtime |
| Management costs | Supervisors, team leaders and operations managers |
| Technology | CRM, dialler, helpdesk and call-recording software |
| Telecommunication | Phone lines, internet and usage charges |
| Training | Onboarding, refresher training and coaching |
| Quality assurance | Call monitoring, audits and calibration |
| Facilities | Office rent, utilities, equipment and maintenance |
| Recruitment | Hiring, assessments and background checks |
| Support functions | IT, workforce management and reporting |
| Outsourcing fees | Provider charges and account-management costs |
Businesses should avoid including some costs for one period and excluding them from another. A consistent calculation method is necessary for meaningful trend analysis.
What Factors Affect Call Center Cost per Call?
Cost per call varies according to the type of work, service level, and operating model.
Average handling time
Longer calls generally require more agent time and increase cost. However, complex billing, complaint or technical calls naturally take longer than simple information requests.
Agent compensation
Salaries, benefits, incentives and overtime often represent a major part of call center spending. Costs can vary by location, required expertise and operating hours.
Call complexity
Technical troubleshooting, regulated processes and sensitive customer concerns usually require more training and longer handling times.
Call volume
Higher volumes may reduce the average cost when existing systems and management resources can support additional calls. Sudden demand increases, however, may require overtime or temporary staffing.
First-call resolution
When customers must call repeatedly about the same issue, the business pays for several interactions instead of one complete resolution.
Technology and integration
Disconnected systems make agents search for information or enter the same data multiple times. Integrated tools can reduce avoidable administrative work.
Staffing accuracy
Understaffing creates long queues and overtime. Overstaffing increases idle time. Both can raise the effective cost of each call.
How Do Inbound and Outbound Call Costs Differ?
Inbound and outbound calls need to be recorded independently as well because both have their own individual purposes.
The main job of Inbound call center services is handling customer queries, complaints, orders, and requests in a systematic manner.
Outbound calls are nothing but starting up business-related calls such as sales calls and appointment calls.
| Support Channel | General Expectation |
|---|---|
| Live chat | Near-immediate response |
| Phone | Answered while the customer remains in the queue |
| Social messaging | Usually faster than email |
| May range from minutes to several business hours | |
| Support tickets | Based on priority and agreed service levels |
An outbound campaign with many unanswered calls may appear inexpensive per dial but costly per meaningful conversation. Businesses should therefore calculate cost per contact, qualified lead or conversion when those measures better reflect the campaign objective.
Why Can a Low Cost per Call Be Misleading?
A falling cost per call may look positive while service quality is declining.
For example, a business may reduce average handling time by encouraging agents to end calls quickly. This can increase repeat contacts, complaints, and escalations when customers do not receive complete answers.
Low costs may also hide:
- Poor first-call resolution
- High employee turnover
- Inadequate training
- Low customer satisfaction
- Incorrect information
- Unresolved technical issues
- Excessive use of transfers
- Missed follow-ups
Call center services cover inbound, outbound, email, chat, and technical interactions, each with different workflows and success measures. Comparing all of them through one cost figure can produce inaccurate conclusions.
How Can Businesses Reduce Cost per Call?
Cost reduction should focus on removing avoidable work rather than weakening customer support.
Improve call routing
Use IVR options, customer information, and skill-based routing to direct calls to the appropriate agent. Better routing can reduce transfers and repeated explanations.
Increase first-call resolution
Provide agents with accurate knowledge resources, suitable system access and clear decision-making authority. Resolving the complete issue can prevent additional calls.
Improve workforce planning
Analyse demand by hour, day and season. Schedule employees according to expected call volume while maintaining flexibility for unexpected peaks.
Simplify agent workflows
Reduce duplicate data entry and unnecessary approval steps. Agents should be able to access customer history, ticket details, and approved guidance from connected systems.
Use self-service for simple requests
Customers may prefer automated options for order tracking, account balances, appointment confirmations, and basic information. A clear path to human support should remain available.
Strengthen training
Effective onboarding and regular coaching can reduce errors, transfers and avoidable escalations. Training should focus on real customer situations rather than scripts alone.
Review repeat-contact reasons
Identify why customers call more than once. Common causes may include incomplete resolutions, unclear instructions, delayed actions or poor coordination between departments.
For complex product and software issues, structured technical support services use ticket categorisation, support levels and documented escalation processes. These controls can help prevent unsuitable transfers and repeated troubleshooting.
Should a Business Outsource Call Center Operations?
Outsourcing may change the cost structure by replacing some recruitment, facilities, technology and supervision expenses with a provider fee.
It may be useful when a business:
- Needs extended operating hours
- Has changing call volumes
- Lacks internal call center expertise
- Wants to avoid building new infrastructure
- Needs a dedicated or flexible support team
- Is expanding into additional regions
However, the quoted price should not be evaluated alone. Businesses should review what the fee includes, such as training, management, quality monitoring, reporting, technology and after-hours coverage.
An outsourcing arrangement can still produce poor value when the scope is unclear, agents receive limited training, or the provider is measured only on call volume.
Which Metrics Should Be Tracked with Cost per Call?
Cost per call should be reviewed alongside operational and customer-experience metrics.
Useful measurements include:
- First-call resolution
- Average handling time
- Customer satisfaction
- Call abandonment rate
- Transfer rate
- Quality assurance score
- Repeat contact rate
- Agent occupancy
- Schedule adherence
- Cost per resolved issue
Cost per resolved issue can be more useful than cost per call because it accounts for repeat interactions.
For outbound operations, businesses may also track cost per contact, appointment, qualified lead, and completed sale.
Build a Cost-Efficient Call Center Without Reducing Quality
The cost per call for a call center becomes valuable where it enables managers to have insights into the use of money and reasons behind increasing operational expenses.
Businesses need to measure the metric continuously and segregate various types of calls and then correlate the cost with resolution quality and customer experience. It is not necessary to try to reduce the duration and cost of every call.
A sustainable way of doing business includes eliminating redundant transfer calls, redundant contact attempts, agent idle time, and unnecessary manual labor.
