Beyond the Salary: The Total Cost of Ownership (TCO) Comparison for In-House IT vs. MSP for Mid-Size Businesses

You know you’re spending money on technology. Salaries, software licenses, that server refresh you’ve been postponing. But when your CFO asks for the true number, the total cost of keeping your business connected, secure, and operational, things get murky fast.

The possible problem might arise when you compare salary figures to MSP quotes as if they were the same thing. But managed IT services for business are not always this intuitive in terms of cost and returns. This article compares the cost of TCO and MSP and how to find the best option for your business.

True Cost of In-House IT

Let’s talk about what that IT person costs you.

The Bureau of Labor Statistics pegs the median IT Support Specialist salary at 60,340 USD. A system administrator earns about 90,520, and an Information Security Analyst earns $124,910 on average. However, those are base salary figures only.

Your cost per employee runs 1.25x to 1.4x that base salary when you factor in:

  • Health insurance;
  • Retirement contributions;
  • Payroll taxes;
  • Workers’ compensation;
  • Paid time off.

The Relentless Challenge of Recruitment & Retention

The Society for Human Resource Management puts the average cost per hire at 4,683 USD across industries. Yet, in tech, this figure varies between 15,000 and $30,000 when you include:

  • Recruiter fees or job posting costs;
  • Interview time with your leadership team;
  • The productivity gap during the vacancy;
  • Onboarding and ramp-up time for the replacement.

The IT industry sees a 13% annual turnover rate according to LinkedIn’s 2023 Workforce Report. For small and mid-size businesses, that number climbs higher because you’re competing against enterprise compensation packages with your SMB budget.

But that is not all. CompTIA estimates the average training investment at $1,500 per IT employee annually. Plus, your IT personnel need power, internet, and office space. So, take it into account when calculating the total cost.

An MSP Defined

An MSP (a managed service provider) is in charge of your tech infrastructure. Most often, you pay a subscription fee. The provider monitors your systems around the clock and fixes any vulnerabilities before they cause damage.

MSP Mode of Operation

Here’s why this distinction is critical:

Break-fix IT:

  • You call when something breaks;
  • Billed by the hour;
  • No incentive to prevent problems;
  • Unpredictable costs;
  • Reactive by design.

MSP model:

  • Continuous monitoring and maintenance;
  • Fixed monthly fee;
  • Incentivized to prevent downtime;
  • Predictable costs;
  • Proactive by design.

If you’re evaluating MSPs but thinking in break-fix terms, you’re asking the wrong questions.

The Core Value Proposition of an MSP

You pay the same amount every month. Instead of one generalist, you get a full roster:

  • Security specialists
  • Cloud architects
  • Compliance experts
  • Help desk technicians
  • Strategic IT consultants

Hiring your third IT person takes months and costs thousands. Scaling up MSP support takes a phone call and maybe a contract amendment.

Service Level Agreements define what you’re getting:

  • Quick response times;
  • Resolution timeframes;
  • Uptime guarantees;
  • Escalation procedures.

When something breaks, you know who’s responsible and when it’ll be fixed.

The True Head-to-Head: A Total Cost of Ownership (TCO) Framework

In-House IT (mid-size business):

RoleBase Salary (BLS May 2024)True Cost (1.4x)
IT Support Specialist$60,340$84,476
Systems Administrator$90,520$126,728
Information Security Analyst$124,910$174,874
Total for 3-person group$275,770$386,078

This doesn’t include recruitment, training, or the opportunity costs we discussed.

MSP pricing (mid-size business):

CompTIA’s 2024 Managed Services Trends report shows MSP pricing typically ranges between 100 and 250 USD per user per month.

Company SizeMonthly Cost RangeAnnual Cost Range
50 employees5,000–12,50060,000–150,000
150 employees15,000–37,500180,000–450,000
300 employees30,000–75,000360,000–900,000

The range is wide because pricing depends on:

  • Service complexity
  • Security requirements
  • Compliance needs
  • Infrastructure age
  • Industry regulations

Indirect Costs

Breach costs vary wildly based on:

  • Data type compromised;
  • Industry regulations;
  • Company size;
  • Public relations damage.

MSPs invest in security tools and expertise that would cost you six figures to replicate in-house. They’re implementing:

  • 24/7 security monitoring.
  • Threat intelligence feeds.
  • Vulnerability scanning.
  • Incident response planning.

Your in-house IT person spends 60-70% of their time on reactive tasks. Password resets. Printer issues. Software updates. User training. That leaves 30% for strategic work. Maybe.

MSPs handle the reactive stuff. That frees your internal resources (if you choose co-managed) or your leadership team to focus on technology that drives revenue.

Scalability & Future-Proofing

You’re growing 20% year-over-year. Fantastic. Yet, the same two people are now supporting 20% more users, devices, and complexity.

Options:

  1. Hire another person (3-6 month process, 15,000-30,000 cost per hire);
  2. Overwork your current staff (hello, turnover);
  3. Let IT restrict growth.

MSPs scale with you. You can just adjust the contract. 

The Co-Managed IT Advantage: A Hybrid Solution

Here’s the option nobody talks about enough. You keep your internal IT person. They know your users, your quirks, and your legacy systems.

The MSP provides:

  • After-hours support;
  • Advanced security monitoring;
  • Compliance expertise;
  • Cloud management;
  • Project-based work (migrations, implementations);
  • Backup and disaster recovery.

Your internal person handles day-to-day tasks. The MSP handles specialized, complex, and after-hours needs.

When Co-Managed Works Well:

  • You have industry-specific software or processes.
  • Your internal person knows the quirks of your niche applications. The MSP handles the infrastructure underneath.
  • You want strategic IT input.
  • Your internal person becomes an IT manager focused on business alignment. The MSP executes the technical heavy lifting.
  • You need 24/7 coverage without burning out staff.
  • Your person works normal hours.

The Cost Math on Co-Managed

Instead of a 3-person internal group at $380,366 annually, you might run:

  • 1-2 internal IT staff: 85,134-253,456 
  • MSP co-managed services: 60,000-180,000 (reduced scope)
  • Total: 145,134-433,456

The upper end looks similar to full in-house, but you’re getting after-hours coverage, specialized security expertise, and scalability you wouldn’t have otherwise.

A Decision Framework

Stop thinking about this as “in-house vs. MSP.” Start thinking about it as “what combination delivers the outcomes I need at a cost I can predict?”

Key Considerations

About your business:

  • How dependent is your revenue on IT uptime?
  • How much time does your IT person spend firefighting vs. planning?
  • When was the last security audit?
  • What’s your average response time for critical issues?
  • Do you have documented disaster recovery procedures?
  • What happens if systems are down for 4-24 hours?
  • Are you in a regulated industry?
  • Can you afford a security breach?
  • What’s your backup strategy if your IT person quits tomorrow?
  • How comfortable are you with technology decisions?

The TCO Comparison Worksheet

Calculate your true in-house costs:

  1. Base salaries for required roles (x1.25-1.4 for total compensation);
  2. Recruitment costs (~13% annual turnover);
  3. Add training costs ($1,500 per employee minimum);
  4. Add equipment and workspace costs;
  5. Estimate the opportunity cost of reactive work.

Compare against MSP quotes that include equivalent coverage. The numbers often surprise business owners who’ve only looked at surface-level comparisons.
