Managed IT vs. an in-house IT person: which costs less?

For most small and midsize businesses, managed IT costs less than a full-time IT hire, and it covers more.

The comparison is rarely salary vs. a monthly fee. The true cost of an in-house IT person includes benefits, tools, training, and the gaps one person cannot cover. The true value of managed IT depends on what the agreement actually includes. Here is how to compare them fairly.

What an in-house IT hire really costs

• Salary. The median annual wage for network and computer systems administrators was $99,130 in May 2025, according to the U.S. Bureau of Labor Statistics. Experienced administrators in competitive markets earn more.
• Benefits and payroll costs. In private industry, benefits make up about 30% of total compensation (BLS, June 2026), which adds roughly 43% on top of wages. That brings a median IT administrator to about $140,000 a year.
• Tools. Monitoring, remote support, patching, backup, endpoint security, and ticketing software all cost money. A single company pays list price for tools that a managed provider spreads across many clients.
• Training and certifications. Microsoft 365, security, and networking change constantly. Keeping one person current takes time and budget.
• Recruiting and turnover. Hiring takes months, and when your only IT person leaves, much of what they know about your systems leaves with them unless it was documented.

What one person cannot cover

• Nights, weekends, vacations, and sick days. Attacks and outages do not wait for business hours. One employee cannot provide 24/7 monitoring and response.
• Every specialty. Help desk, Microsoft 365, networking and Wi-Fi, cybersecurity, compliance, and vendor management are different skill sets. Most generalists are strong in some and thin in others.
• A second set of eyes. A single administrator often has unchecked access to everything. That is a security risk of its own, especially if the relationship ends badly.

What managed IT typically includes

A managed IT agreement usually covers a team instead of a person, for a predictable monthly fee that scales with your headcount:

• Help desk support for your employees
• 24/7 monitoring of devices and systems
• Patch management and software updates
• Security tools, such as endpoint protection, email security, and identity monitoring
• Backup and recovery
• Onboarding and offboarding of employees and devices
• Documentation of your environment, so knowledge is not locked in one person’s head
• Strategic planning, such as budgets, hardware lifecycle, and technology roadmaps

What is included varies widely between providers, which is why comparing quotes line by line matters.

When in-house IT makes sense

An in-house IT person can be the right choice when:

• You have enough employees and devices to keep a full-time person busy every day
• You need someone physically on site for frequent hands-on work, such as labs, production floors, or specialized equipment
• You run custom or industry-specific systems that need daily care from someone who knows your business deeply

Even then, many organizations pair their internal IT staff with a managed provider. This is called co-managed IT: your IT person handles day-to-day and on-site needs, while the provider supplies 24/7 monitoring, security tools, specialized skills, and backup coverage.

How to compare a managed IT quote with a hire

Ask each provider:

1. What exactly is included in the monthly fee, and what is billed separately?
2. What are the response times, and are they in the contract?
3. Is cybersecurity included, or is it an add-on?
4. Is support available after hours, and is monitoring truly 24/7?
5. Is there an onboarding fee?
6. What is the contract length, and what happens if we leave?
7. Will we own our documentation and administrator credentials?

Then compare the total against the fully loaded cost of a hire, not just the salary.
