How to Calculate Cost Per Call With the Tool
- Step 1: Choose what you're measuring - Decide whether the calculation is for one agent or a complete team.
- Step 2: Enter the operating cost - Add the total relevant cost for the period you want to analyze.
- Step 3: Enter the calls handled - Add the total number of calls completed during that same period.
- Step 4: Calculate the result - The calculator divides the operating cost by the call volume and displays the average cost per call.
Cost Per Call Formula: How It Works
The calculation uses a simple formula:
Cost Per Call = Total Operating Cost ÷ Total Calls Handled
For useful comparisons, use the same measurement period and cost categories when reviewing different teams or months.
Common Cost Per Call Calculation Errors
- Using mismatched periods: Make sure your operating costs and call count cover the same period.
- Leaving out important costs: Decide which expenses belong in your calculation and apply the same approach each time.
- Counting the wrong calls: Use a consistent definition of handled calls when calculating and comparing results.
- Combining different call types: Technical or complex calls may require more time and resources than simple interactions.
- Comparing unlike teams: Teams differ in staffing levels, workloads, call types, and operating costs.
- Treating lower cost as better performance: A lower cost per call does not automatically mean better customer service.
- Ignoring service quality: Review cost together with customer satisfaction, resolution rates, and other service metrics.
What Can Cost Per Call Tell You?
Cost per call shows the average operating cost associated with handling one phone call.
It can help businesses review:
- Call-handling expenses
- Team operating costs
- Changes in call volume
- Cost trends
- Staffing expenses
- Overall call-handling efficiency
Cost Per Call vs. Cost Per Agent
These metrics provide different views of contact center costs.
Cost Per Call shows the average cost of handling each call.
Cost Per Agent looks at the cost associated with an individual employee during a selected period.
For example, if a contact center spends $40,000 to handle 8,000 calls, its average cost per call is $5.
If the same operation has 20 agents, calculating the cost per agent requires separate information about how labor and other operating costs are assigned.
