TL; DR Summary
- In-house centers cost $2.6–$4.4M annually for 50 agents with mostly fixed expenses regardless of volume
- Outsourcing delivers 43–66% savings ($1.2–$2.1M annually domestic) through variable pricing and eliminated overhead
- Hidden costs exist in both: in-house faces scalability friction, outsourcing introduces quality control challenges and contract lock-in
- Decision depends on support complexity, brand criticality, data sensitivity, and whether the service is core to the competitive advantage
- AI voice agents reduce per-contact costs by 60–80% while handling routine inquiries and freeing humans for complex work
Introduction
Your call center costs keep climbing. Every quarter, the numbers get worse.
Wages, benefits, office space, technology, training, and turnover. The costs add up faster than you can make them better. Then someone brings up outsourcing, and all of a sudden you're evaluating savings against control.
The call center outsourcing cost decision isn't about finding the cheapest option. It's about being aware of what you're truly getting and what you're giving up.
Let's look at the numbers and discover which strategy works best for your business.
What You're Really Paying for In-House Operations
Internal call centers have obvious costs and hidden ones that sneak up on you.
The Labor Bill
Call center agents in the US make between $32,000 and $42,000 a year. With benefits that are 30–40% of the pay, each agent makes $41,600–$58,800.
A 50-agent center hits $2.08–$2.94 million in labor costs alone. That's before anyone answers a single call.
Infrastructure That Scales Painfully
Office space in major markets runs $3,000–$8,000 per employee annually. A center with 50 chairs needs around 7,500 square feet of space.
Then you can add workstations, computers, headsets, and phones for between $1,500 and $3,000 per seat.
Technology Stack That Multiplies
Basic contact center software costs $50–$150 per user monthly. Adding tools for CRM integration, managing your personnel, and keeping an eye on quality will cost you $80 to $250 per seat per month.
For 50 agents, plan to spend between $48,000 and $150,000 a year just on software.
The Turnover Tax
It costs between $3,000 and $6,000 to train a new agent. With an average turnover rate of 30–45% per year, a team of 50 agents loses 15–23 people every year.
Replacement costs hit $45,000–$138,000 just to maintain headcount. That doesn't count lost knowledge or service quality dips.
Management Overhead
Supervisors who have 8 to 12 agents under them make between $45,000 and $65,000 a year, with perks. A 50-agent center needs 6–8 support personnel.
That's another $270,000–$520,000 annually in management costs.
The brutal reality? These costs of in-house call centers stay mostly fixed, whether you're handling 10,000 calls or 50,000 calls monthly.
How Outsourcing Changes the Math
Call center outsourcing cost models shift fixed expenses to variable pricing.
Three Main Pricing Models
Per-minute pricing charges $0.75–$1.50 per minute of talk time. Pay between $75,000 and $150,000 for 100,000 minutes each month.
This scales with volume but gets expensive for longer calls. An 8-minute average means $6–$12 per interaction.
Per-call pricing typically runs $3–$8 per handled call. Basic questions go at the bottom, while technical support goes to the top.
Allocate $30,000 to $80,000 each month for 10,000 calls.
Dedicated agent pricing is the most predictable option:
- Domestic US: $2,000–$3,500 per agent monthly
- Nearshore (Latin America): $800–$1,500 per agent monthly
- Offshore (Philippines, India): $500–$1,200 per agent monthly
The monthly cost of a 50-agent team is between $100,000 and $175,000 domestically or between $25,000 and $60,000 internationally.
What's Included (and What's Not)
Most providers handle recruiting, training, infrastructure, and technology. You're buying outcomes, not managing overhead.
But watch for hidden fees. Setup charges ($5,000–$25,000), minimum commitments, integration costs, and early termination penalties all impact total expense.
Quality monitoring and advanced reporting often cost extra.
Running the Actual Numbers
Let's look at the real expenditures for a 50-agent company that handles 25,000 calls a month.
In-House Annual Costs
- Labor: $2,080,000–$2,940,000
- Management/support: $270,000–$520,000
- Office space: $150,000–$600,000
- Technology: $48,000–$150,000
- Training/turnover: $45,000–$138,000
- Equipment: $30,000–$75,000
Total: $2,623,000–$4,423,000
Outsourced Annual Costs (Domestic)
- Dedicated FTE model: $1,200,000–$2,100,000
- Per-call model at $5 average: $1,500,000
- Per-minute model at $1 average: $1,800,000
Potential savings: $1,123,000–$2,923,000 annually
That's 43–66% cost reduction with domestic outsourcing. Nearshore or offshore options push savings to 60–80%.
But raw numbers don't tell the whole story.
The Hidden Costs Nobody Mentions
Both approaches carry expenses that surprise you later.
In-House Hidden Costs
Management bandwidth gets consumed by HR drama, scheduling conflicts, and performance issues. Your executives spend hours on operations instead of strategy.
Technology debt accumulates. Systems age and require expensive upgrades you didn't budget for.
Scalability creates painful friction. Doubling capacity means doubling everything: space, equipment, hiring pipelines. Ramp-up takes 3–6 months minimum.
Outsourcing Hidden Costs
Knowledge transfer during onboarding takes longer than expected. Process gaps create service inconsistencies.
Quality control becomes harder when agents aren't in your building. You need formal monitoring processes instead of walking the floor.
Contract lock-in creates strategic risk. Most agreements require 12–36 month commitments with steep exit penalties.
The question isn't which approach has fewer hidden costs. It's which ones you're equipped to manage.
When Outsourcing Makes Perfect Sense
Call center outsourcing cost advantages peak under specific conditions.
- Seasonal businesses avoid year-round staffing costs. Retailers ramping up for holidays or tax companies handling January–April surges pay only for capacity when needed.
- Growing companies solve hiring bottlenecks fast. Building a 20-person team takes months. Outsourcing deploys that capacity in weeks.
- Cost-sensitive operations where margins can't support $50–$80 per agent hour find immediate relief at $25–$40 outsourced rates.
- Non-core competency situations make sense, too. If customer service isn't your competitive advantage, why build internal expertise?
When In-House Operations Win
Some scenarios demand internal control regardless of cost advantages.
- High-complexity support requires deep product knowledge that's hard to transfer. Medical device companies or enterprise software providers often keep support internal.
- Brand-critical interactions justify premium costs. Luxury brands or high-touch services need agents who embody brand values authentically.
- Data sensitivity sometimes mandates internal operations. Healthcare (HIPAA), financial services (PII), or defense contractors can't easily outsource.
- Strategic customer insights get lost in outsourcing. Your agents hear feature requests and competitive intelligence daily. In-house teams share that naturally.
- Long-term cost trajectories favor in-house at scale. A 200+ seat operation with mature processes might find internal costs competitive after absorbing setup expenses.
Making Your Decision
The call center outsourcing vs. in-house costs calculation isn't purely mathematical.
Run the numbers honestly. Calculate your true in-house costs, including everything: turnover, management time, technology, and office space.
Then model outsourcing scenarios with realistic volume projections and contract terms.
Assess your operational maturity. Companies with documented processes and clear KPIs transition more successfully. Organizations still figuring out their service model struggle with vendor management.
Consider hybrid approaches. Some businesses outsource after-hours while keeping core hours internal. Others handle tier-1 through providers and retain complex escalations in-house.
Test before committing. A 90-day pilot with 5–10 agents costs $10,000–$35,000 but prevents million-dollar mistakes.
What you should do depends on your business model, how fast you want to expand, and what your strategic goals are.
The AI Alternative That Changes Everything
Traditional comparisons assume human agents handle every interaction. That's changing.
AI answering service solutions reshape the economics entirely. Instead of choosing between $50/hour in-house or $25/hour outsourced agents, businesses deploy AI at $0.10–$0.50 per conversation.
The math shifts when 40–60% of calls get resolved by AI before reaching humans.
Savings compound beyond direct cost reductions. AI handles after-hours without night shift premiums. It scales instantly during spikes without capacity planning. Call quality stays consistent.
This isn't about replacing your entire contact center with robots. It's redesigning workflows so humans focus on complex issues while AI handles routine questions.

Frequently Asked Questions
How much does it cost to outsource a call center?
Dedicated teams from US companies cost $2,000 to $3,500 per agent each month. Nearshore costs 40–60% less, and offshore costs 60–75% less.
The average monthly cost of a 50-agent operation is between $100,000 and $175,000. The cost is between $40,000 and $75,000 nearshore, or between $25,000 and $60,000 offshore.
What is the highest cost in a call center?
Labor dominates both models, representing 60–70% of total expenses. For internal centers, this includes salaries, benefits (30–40% of base), management, and turnover costs.
Even in outsourced models, the per-agent fees you pay primarily compensate provider labor costs.
How to calculate call center outsourcing costs?
Start with monthly call volume and average handle time. Multiply calls by average cost per call ($3–$8) or minutes by per-minute rate ($0.75–$1.50).
For dedicated models, figure out how many agents you need based on volume and service requirements, then multiply that number by the monthly cost per agent ($2,000–$3,500 in the US).
Add setup fees of $5,000 to $25,000 and a 10% to 15% buffer for changes in volume.
