Maintaining an in-house call center can be costly and inefficient. The Hit Rate Solutions ROI Calculator helps businesses compare their current overhead to an outsourcing model and estimate savings when using our inbound call center outsourcing capabilities.
How the Call Center ROI Calculator Works
We estimate your ROI using three core inputs:
- Your current cost structure: Monthly call volume, average handle time, in-house hourly rate, and phone/software spend.
- Your outsourcing scope: The percentage of your call volume you plan to route to Hit Rate Solutions.
- Hourly rate comparison: The difference between your in-house hourly rate and a typical Hit Rate Solutions hourly rate, plus a proportional reduction in phone and software costs.
Step 1: Calculate Your Monthly Call Center Costs
To calculate ROI, you need four core inputs:
- Monthly call volume: Total number of inbound (or outbound) calls handled per month.
- Average Handle Time (AHT): Average minutes per call, including talk time, hold time, and after-call work.
- Fully loaded hourly rate: This is more than just wages. Include base pay, benefits, payroll taxes, paid time off, training, supervision, and attrition costs. In the U.S., fully loaded rates typically range from $18–$28/hour, depending on location.
- Monthly phone & software costs: Include costs for dialers and VoIP systems, CRM licenses, workforce management tools, and QA and reporting platforms.
Step 2: Calculate Total Monthly Labor Hours
Formula:
Monthly Call Volume × AHT (minutes) ÷ 60 = Total Labor Hours
Example:
- 6,500 calls × 4 minutes = 26,000 minutes
- 26,000 ÷ 60 = 433 labor hours
Step 3: Calculate Total Monthly Cost
Example:
- Fully loaded hourly rate: $22
- Labor cost: 433 hours × $22 = $9,533
- Add infrastructure: $2,800 (phone/software)
- Total monthly cost: $12,333
Step 4: Calculate Cost Per Call
Total Monthly Cost ÷ Total Calls = Cost Per Call
- $12,333 ÷ 6,500 = $1.89 per call
Many companies never calculate this — making outsourcing comparisons difficult.
Hidden Costs Most Companies Overlook
Even the formula above doesn't capture everything. Consider adding shrinkage (breaks, meetings, sick time), training ramp time for new agents, hiring and recruitment costs, QA rework and supervision overhead, and turnover replacement costs.
Factoring these in can push your true cost per call up by 25–45% above expectations.
Example Call Center Outsourcing ROI Scenario
Here's a simplified example of the model. To illustrate how it works, let's use a realistic sample configuration.
Imagine a mid-sized business with the following profile:
- 20 in-house agents
- $22/hour in-house rate
- 6,500 monthly calls
- 4-minute average handle time (AHT)
- $2,800/month in phone & software costs
- 50% of call volume outsourced to Hit Rate Solutions at $7/hour
Based on this profile, here's how the numbers break down:
- Labor: 433 hours × $22/hr = $9,533
- Phone/Software: $2,800
- Total: $12,333/month
After outsourcing 50% of call volume, you’ll get:
- In-house labor: 217 hours × $22/hr = $4,774
- Outsourced labor: 217 hours × $7/hr = $1,519
- Phone/Software: $1,400 (50% reduction)
- Total: $7,693/month
- Monthly Savings: $4,640
- Annual ROI: $55,680
This example demonstrates three key benefits of outsourcing inbound call center:
- Lower labor spend: $3,240/month in labor cost reduction by leveraging our $7/hr rate vs. your $22/hr in-house cost.
- Reduced tech overhead: Phone and software costs drop proportionally with outsourced volume, saving an additional $1,400/month.
- Additional capacity: Our specialized agents handle calls more efficiently, giving you room to scale without adding overhead.
Why Outsourcing Improves ROI Beyond Hourly Rates
Smart decision-makers don't outsource just for cheaper labor — they do it for structural efficiency:
- Convert fixed costs into variable costs: Outsourcing enables scalable staffing, allowing capacity to be adjusted without layoffs or hiring cycles.
- Reduce management overhead: Supervisors, QA managers, trainers, and workforce planners are handled by your outsourcing partner.
- Lower infrastructure risk: Licensing, upgrades, IT support, and security compliance are shifted off your balance sheet.
- Handle volume spikes without hiring: Seasonal fluctuations, marketing campaigns, or unexpected surges can be managed seamlessly.
When Call Center Outsourcing Makes Financial Sense
Outsourcing is most effective when call volumes fluctuate, internal cost per call exceeds $1.50–$2.00, attrition rates are high, after-hours coverage is required, rapid scaling is needed, or leadership wants to focus on strategic initiatives.
Most companies start by outsourcing 30%–80% of call volume, including overflow calls, after-hours support, appointment scheduling, lead qualification, and outbound campaigns.
