Most businesses run this comparison the wrong way. They set a single IT salary next to a monthly managed services invoice, see the smaller number, and hire. Two years later the math looks nothing like the spreadsheet that justified the decision. The reason is simple. A salary is the one cost of in-house IT that is easy to see, and it is rarely the one that decides the outcome.
This is a question of in-house IT costs vs managed services, and it turns on the costs that never make it onto a job offer. Once you load a hire with benefits, tooling, training, coverage gaps, and the price of the hours one person cannot cover, the combined figure often crosses the line where an MSP would have delivered more capability for less money. The useful question is not which model is cheaper in the abstract. It is knowing when to outsource IT: the point at which in-house IT starts costing your specific business more than managed services would.
When does in-house IT cost more than managed services?
For most organizations under roughly 75 employees, in-house IT costs more than managed services once the full burden of a hire is counted. A single salaried technician carries benefits worth about 40 percent on top of base pay, plus tooling, recruiting, and the unavoidable gaps when one person cannot cover nights, holidays, sick days, and every technical discipline at once. A comprehensive managed services contract typically absorbs all of that for a predictable monthly fee, which is why the crossover almost always favors the outsourced model at the smaller end of the market.
The tipping point shifts with size and complexity. The sections below break down what each model actually costs and where the line sits for a business like yours.
What a single in-house IT hire actually costs
Start with the number everyone quotes: base salary. According to the U.S. Bureau of Labor Statistics, the median annual wage for network and computer systems administrators was $96,800 in May 2024, and the top ten percent earned more than $150,320. An IT manager sits far higher, at a median of $171,200. Those are base wages only.
Now load them. BLS Employer Costs for Employee Compensation data shows benefits and legally required contributions account for close to 30 percent of total compensation in private industry, which works out to roughly 40 percent on top of base pay when you measure it against salary alone. Add the software, monitoring, and security licensing one person needs to do the job, the recruiting and onboarding spend to fill the seat, and the training required to keep skills current. The fully loaded cost of an IT employee lands in the $110,000 to $150,000 range once every expense is added in, well before you have bought a second pair of hands.
And one hire buys exactly one calendar. When that person is on leave, asleep, or out of their depth on a discipline they were never trained for, coverage simply stops.
The hidden costs that never appear on the job offer
This is where the false baseline does its damage. The salary sits on the payroll and the laptop sits in the capex, but the expensive parts of in-house IT live off the books.
- Turnover and replacement: IT roles churn, and every departure restarts recruiting, onboarding, and ramp time while institutional knowledge walks out the door.
- After-hours and on-call coverage: A 2 a.m. server failure either waits until morning, which carries its own cost, or triggers overtime and on-call arrangements that were never in the salary line.
- Coverage gaps: Holidays, sick days, and vacations leave a one-person function with no redundancy.
- The generalist ceiling: Modern IT spans helpdesk, networking, cloud, endpoint management, cybersecurity, and compliance. No single hire is a genuine expert across all of it, and the gaps are exactly where risk accumulates.
- Downtime: Industry estimates commonly place the cost of an outage for a mid-size business in the thousands to well over ten thousand dollars per hour, depending on size and sector. Reactive, single-person IT lengthens both the detection and the recovery window.
- Compliance blind spots: Frameworks such as HIPAA, PCI DSS, and CMMC demand specialized knowledge that most generalist hires do not carry.
Add these together and the reason companies underestimate their in-house spend becomes clear: they compare headline costs when the honest cost of in-house IT vs outsourcing is a full-picture number. The infographic below stacks the visible salary against everything hidden beneath it.
What do managed IT services cost?
Managed services are almost always billed as a fixed recurring fee, which keeps the cost predictable and easy to scale. Across current U.S. pricing guides, the managed IT services cost per user runs $100 to $300 per month. The middle of that band covers monitoring, patching, helpdesk, backup, and a baseline security stack, while the upper end adds 24/7 support, advanced security, and strategic guidance.
What matters is what that single line item replaces. Instead of one generalist, you contract a team: helpdesk technicians, network engineers, security analysts, and compliance specialists, along with the monitoring and security platforms already licensed across the vendor’s client base. A widely cited CompTIA survey found that a large share of businesses reduce their annual IT spend after moving to managed services, and the mechanism is straightforward. The fee is fixed, the coverage does not take vacations, and adding or removing users is a line-item adjustment rather than a hiring cycle.
In-house IT vs managed services, side by side
The table below compares the two models on the factors that actually move the total cost of ownership, not just the sticker price.
Factor | In-House IT | Managed Services |
Cost structure | Salary, benefits, tooling, and overhead | Fixed per-user monthly fee |
Typical cost | About $110,000 to $150,000 fully loaded per hire | About $100 to $300 per user, per month |
Coverage | One person, one calendar | A team, from business hours to 24/7 |
Expertise | Generalist with depth in one or two areas | A bench of specialists across disciplines |
After-hours support | Overtime or on-call, or it waits until morning | Included per contract tier |
Scalability | Requires a new hire | A line-item adjustment |
Turnover risk | Knowledge leaves with the person | Absorbed by the provider |
Security and compliance | Depends on one hire’s skill set | Built-in stack and specialists |
Best fit | 200+ employees or specialized needs | Under ~75 employees or growing SMBs |
At what company size should you outsource IT?
- Under roughly 75 employees: The math rarely favors building internally. One hire cannot cover the full scope, and its total cost usually exceeds a comprehensive managed services contract that delivers more.
- Between 75 and 200 employees: It gets nuanced. Many organizations here land on co-managed IT services, keeping an internal coordinator or small team for business-specific priorities while a provider handles monitoring, security, after-hours coverage, and specialist depth.
- Above roughly 200 employees: An internal team of three to five specialists across different disciplines becomes viable, and in-house teams or co-managed IT services start to make financial and strategic sense.
When in-house IT still makes sense
Managed services are not automatically the answer, and any analysis that claims otherwise is selling something. Building internally is the stronger call when your organization is large enough to staff a genuine multi-disciplinary team, when your technology is core intellectual property you do not want to place with a third party, when you run real-time or highly specialized systems that demand dedicated ownership, or when regulatory requirements favor in-house control. The right model follows your size, complexity, and strategic direction, not a slogan.
How to run the numbers for your own business
To compare the cost of in-house IT vs outsourcing honestly, skip the salary-versus-invoice shortcut. Build the true, all-in cost of the in-house option first: base pay, benefits at roughly 40 percent, tooling and licensing, recruiting, training, and a realistic figure for turnover. Assign a dollar value to an hour of downtime for your business, and account for the coverage gaps a single hire leaves open. Then run the comparison over three years rather than one, because the model that looks cheaper in year one is often the more expensive and riskier choice by year three. If you land in the middle band, price a co-managed arrangement alongside both extremes before you decide.
The businesses that regret this decision are almost always the ones that compared headline numbers instead of full ones. Run the numbers in full for your own headcount, and the point where in-house IT costs more than managed services usually becomes obvious.

Frequently asked questions
When does in-house IT cost more than managed services?
In-house IT usually costs more than managed services for businesses under roughly 75 employees. Once you add benefits of about 40 percent, tooling, recruiting, training, and coverage gaps to a single salary, the fully loaded cost of one hire, around $110,000 to $150,000, typically exceeds a comprehensive managed services contract that delivers more.
Is managed IT cheaper than in-house?
For most small and mid-sized businesses, managed IT is cheaper than in-house. The real comparison is not a salary against an invoice. It is one generalist, loaded with benefits and tools, against an outsourced team of specialists for a fixed monthly fee. Below about 75 employees, that model almost always wins on cost and coverage.
How much do managed IT services cost?
The managed IT services cost per user typically runs $100 to $300 per month in the US, billed as a fixed monthly fee. The middle of that range covers monitoring, patching, helpdesk, backup, and a baseline security stack. The upper end adds 24/7 support, advanced security, and strategic guidance, all for a predictable price.
How much does an in-house IT employee really cost?
The fully loaded cost of an IT employee runs about $110,000 to $150,000 per year. The base salary is only the start. The U.S. Bureau of Labor Statistics puts the median wage for network and systems administrators at $96,800 in May 2024, and benefits, tooling, recruiting, training, and turnover push the real figure much higher.
At what company size should you outsource IT?
Businesses under roughly 75 employees should almost always outsource IT, because one hire cannot cover the full scope for less than a managed contract. Between 75 and 200 employees, a co-managed model often fits best. Above about 200 employees, an internal team of three to five specialists becomes viable.
What are the hidden costs of in-house IT?
The hidden costs of in-house IT include benefits of about 40 percent on top of salary, software and security licensing, recruiting and onboarding, training, and turnover. Add after-hours and on-call coverage, gaps during PTO and sick days, downtime, and compliance risk. These off-the-books costs are why companies underestimate their true in-house spend.
