Understanding Cost Per Call
What is Cost Per Call (CPC)?
Cost Per Call (CPC) is a marketing and business metric that measures the average expense associated with each phone call received or made as part of a specific activity, like a marketing campaign, a sales initiative, or customer support operations. It helps evaluate the efficiency and cost-effectiveness of these activities.
Cost Per Call Formula
The formula is straightforward:
Cost Per Call = Total Cost / Total Number of Calls
Where:
- Total Cost is the sum of all relevant expenses over a period.
- Total Number of Calls is the count of calls attributed to those expenses over the same period.
Why is CPC Important?
- Measure Marketing ROI: Assess how efficiently marketing campaigns focused on driving phone calls are performing.
- Evaluate Sales Efficiency: Understand the cost of generating leads or closing deals via phone calls.
- Optimize Support Costs: Analyze the expense associated with handling customer inquiries over the phone.
- Budgeting: Helps forecast costs based on expected call volumes.
A lower Cost Per Call generally indicates better efficiency, but it should always be considered alongside the *quality* of those calls (e.g., lead conversion rate, customer issue resolution).
Cost Per Call Examples
See how the calculator works with different scenarios:
Example 1: Simple Marketing Campaign
Scenario: A small business runs an ad campaign specifically asking people to call. Over one month, the campaign cost $1000 and resulted in 200 phone calls.
1. Known Values: Total Cost = $1000, Total Number of Calls = 200.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $1000 / 200 Calls
4. Result: Cost Per Call = $5.00.
Conclusion: Each call from this campaign cost an average of $5.
Example 2: Sales Team Performance
Scenario: A sales team's combined salary, bonuses, and phone expenses for a quarter total $50,000. They made 1500 sales calls during that quarter.
1. Known Values: Total Cost = $50,000, Total Number of Calls = 1500.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $50,000 / 1500 Calls
4. Result: Cost Per Call ≈ $33.33.
Conclusion: The average cost of a sales call for this team is approximately $33.33.
Example 3: Customer Support Line
Scenario: The monthly operational cost for a customer support call center (staff, telecom, software) is $20,000. They handle 4000 customer calls per month.
1. Known Values: Total Cost = $20,000, Total Number of Calls = 4000.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $20,000 / 4000 Calls
4. Result: Cost Per Call = $5.00.
Conclusion: Each customer support call costs the company an average of $5.
Example 4: Local Business Ad
Scenario: A local pizza shop spends $300 on radio ads in a week. They track 75 calls directly from people mentioning the ad.
1. Known Values: Total Cost = $300, Total Number of Calls = 75.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $300 / 75 Calls
4. Result: Cost Per Call = $4.00.
Conclusion: The cost per call from the radio ad is $4.
Example 5: Online Lead Generation
Scenario: An online campaign designed to get users to click a "Call Now" button costs $1500 over a month and results in 125 phone calls.
1. Known Values: Total Cost = $1500, Total Number of Calls = 125.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $1500 / 125 Calls
4. Result: Cost Per Call = $12.00.
Conclusion: Each call generated by this online campaign costs $12.
Example 6: Direct Mail Campaign
Scenario: A company sends out 1000 direct mail pieces costing $0.80 each (total $800). They receive 40 tracked phone calls from the mailing.
1. Known Values: Total Cost = $800, Total Number of Calls = 40.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $800 / 40 Calls
4. Result: Cost Per Call = $20.00.
Conclusion: The direct mail campaign generated calls at an average cost of $20 per call.
Example 7: Comparing Two Channels
Scenario: Channel A cost $2000 and got 100 calls. Channel B cost $3000 and got 120 calls. Calculate CPC for each.
Channel A: Cost = $2000, Calls = 100. CPC = $2000 / 100 = $20.
Channel B: Cost = $3000, Calls = 120. CPC = $3000 / 120 = $25.
Conclusion: Channel A had a lower Cost Per Call ($20) than Channel B ($25), indicating better cost efficiency in generating calls.
Example 8: Zero Calls Received
Scenario: A campaign costs $500 but receives 0 phone calls.
1. Known Values: Total Cost = $500, Total Number of Calls = 0.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $500 / 0 Calls
4. Result: The calculator will show an error for division by zero.
Conclusion: When there are no calls, the Cost Per Call is undefined or infinitely high, indicating complete inefficiency in generating calls from that spend.
Example 9: Very High Call Volume
Scenario: A viral social media post directs users to call a number. The cost for the post is minimal ($50), but it drives 5000 calls.
1. Known Values: Total Cost = $50, Total Number of Calls = 5000.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $50 / 5000 Calls
4. Result: Cost Per Call = $0.01.
Conclusion: A very low Cost Per Call ($0.01) indicates extremely high efficiency in generating calls relative to the cost.
Example 10: Tracking Over Time
Scenario: A campaign runs for two months. Month 1: Cost $800, Calls 150 (CPC = $5.33). Month 2: Cost $1200, Calls 250 (CPC = $4.80). Calculate overall CPC.
1. Known Values (Overall): Total Cost = $800 + $1200 = $2000, Total Number of Calls = 150 + 250 = 400.
2. Formula: Cost Per Call = Total Cost / Total Number of Calls
3. Calculation: $2000 / 400 Calls
4. Result: Cost Per Call = $5.00.
Conclusion: The overall Cost Per Call for the two months is $5.00, showing a slight improvement from Month 1 to Month 2.
Frequently Asked Questions about Cost Per Call
1. What expenses should I include in "Total Cost"?
This depends on what activity you're measuring. For marketing campaigns, include ad spend, agency fees, landing page costs, etc. For sales teams, include salaries, commissions, phone service, CRM costs. For support, include agent wages, telecom costs, software, overhead. Ensure you include *all* relevant costs for the specific activity and time period you're analyzing.
2. How do I accurately count "Total Number of Calls"?
Use call tracking software, unique phone numbers for different campaigns/channels, or CRM logging for outbound calls. It's crucial that the calls counted are directly related to the costs being measured in the same period.
3. Can I have a Cost Per Call of zero?
Only if your Total Cost is zero. If you have a cost greater than zero but zero calls, the CPC is undefined (the calculator will show an error). If both cost and calls are zero, the calculation isn't meaningful.
4. What is considered a "good" Cost Per Call?
There's no universal "good" CPC. It varies greatly by industry, the value of the call (e.g., a sales lead vs. a quick support question), the campaign's goal, and the complexity of the service. The best approach is to compare CPC:
- Across different marketing channels (e.g., radio vs. online ads).
- Over time for the same activity to track performance changes.
- Against your business goals and the potential revenue/value each call brings.
5. How can I reduce my Cost Per Call?
Ways to reduce CPC include:
- Optimizing marketing spend to target more qualified leads.
- Improving ad copy or messaging to attract callers more efficiently.
- Enhancing call handling processes to reduce abandoned calls or misrouted calls.
- Increasing the efficiency of the team making/receiving calls.
- Leveraging lower-cost channels that still deliver call volume.
6. Is Cost Per Call the only metric I should track?
No. CPC is primarily a cost efficiency metric. You should always pair it with quality metrics like:
- Call duration
- Conversion rate (e.g., calls that become leads, sales, or resolved issues)
- Customer satisfaction scores
- Revenue generated per call
7. Can this calculator be used for both inbound and outbound calls?
Yes. As long as you can clearly define and measure the "Total Cost" and the corresponding "Total Number of Calls" (whether incoming or outgoing) for a specific activity or team, the formula and calculator apply.
8. What if I have calls that didn't come from a specific campaign?
For accurate CPC calculation related to a *specific* activity (like a marketing campaign), only include the calls directly attributed to that activity and the costs associated with it. For an overall business CPC, you would include total company costs related to all call handling and the total volume of all relevant calls.
9. Why might my calculated CPC differ from my expectations?
Discrepancies often arise from:
- Missing or incomplete cost data.
- Inaccurate call tracking or counting.
- Calls being misattributed to the wrong source or campaign.
- Using different time periods for cost tracking vs. call counting.
10. Can I use different currencies or units?
Yes, the calculator works with any numerical value. Just ensure that your "Total Cost" is in a consistent currency or unit (e.g., USD, EUR, GBP) and the result will be in that same unit per call.
