The managed IT vs in-house IT cost debate comes down to a single question most business owners answer wrong: are you comparing sticker prices, or total costs? The salary of one IT hire looks cheaper than an MSP contract on paper. Add benefits, PTO, turnover, tool licensing, skills gaps, and the hours you personally spend managing an underqualified generalist, and the picture inverts fast.

This article gives you the real numbers — dollar ranges for 50, 100, and 200 employees across both models, a breakdown of every hidden cost in each approach, and a decision framework for figuring out which structure actually fits your business. No vendor spin. No vague recommendations. Just the math.

68%

of SMBs that switched from in-house to managed IT cited unexpected total employment costs — not technology issues — as the primary trigger for the change, according to a 2025 SMB technology operations survey.

Managed IT vs In-House IT Cost Breakdown by Company Size

The comparison below covers full-service managed IT (help desk, security monitoring, patching, backups, and vCIO/strategic guidance) against a fully-loaded in-house IT team sized appropriately for each company size. These are realistic market ranges for the US, not best-case scenarios.

Cost Category Managed IT (MSP) In-House IT
50 Employees
Core IT coverage $45,000–$84,000/yr
$75–$140/user/mo		 $95,000–$135,000/yr
1 IT generalist, fully loaded
Tool licensing Included in MSP fee $8,000–$18,000/yr
RMM, ticketing, backup, EDR
After-hours coverage Included (24/7 monitoring) $5,000–$15,000/yr
On-call stipend or overtime
Recruiting / turnover risk None (MSP absorbs) $10,000–$40,000 per hire cycle
Avg IT turnover: 13% annually
Annual total (Year 1) $45,000–$84,000 $118,000–$208,000
100 Employees
Core IT coverage $84,000–$156,000/yr
$70–$130/user/mo (volume discount)		 $210,000–$290,000/yr
IT manager + 1 help desk technician
Tool licensing Included $14,000–$28,000/yr
After-hours coverage Included $8,000–$20,000/yr
Recruiting / turnover risk None $15,000–$60,000 per hire cycle
Annual total (Year 1) $84,000–$156,000 $247,000–$398,000
200 Employees
Core IT coverage $156,000–$264,000/yr
$65–$110/user/mo (volume discount)		 $380,000–$520,000/yr
IT manager + 2 technicians + security lead
Tool licensing Included $22,000–$45,000/yr
After-hours coverage Included $12,000–$30,000/yr
Recruiting / turnover risk None $20,000–$80,000 per hire cycle
Annual total (Year 1) $156,000–$264,000 $434,000–$675,000

The in-house numbers look large because they are. Salary is only part of it. A $90,000 IT hire costs you $126,000–$144,000 when you include benefits (25–35% loaded), FICA, PTO, and management overhead. Tool licensing adds another $8,000–$18,000. And at 50 employees, one IT generalist is stretched thin — security, networking, help desk, vendor management, and strategic planning all land on the same desk.

Hidden Costs of Managed IT Services

MSP pricing looks clean until you start reading the contract. The monthly per-user fee covers a defined scope — and everything outside that scope is billable at hourly rates that typically run $150–$250/hour.

Out-of-Scope Project Billing

New office setup, major software migrations, firewall replacements, and cloud architecture work are almost never included in a standard MSP agreement. A 50-person office move might generate $8,000–$25,000 in out-of-scope project bills on top of your monthly fee. MSPs are transparent about this — it’s in the contract — but first-time buyers routinely underestimate project frequency. Budget a project contingency of 15–25% of your annual MSP fee.

Response Time Tier Upsells

Base MSP agreements often carry 4–8 hour response time SLAs for non-critical issues. If your business operations can’t absorb a 4-hour wait when a system goes down, you need a premium tier. Expect to pay 20–40% more for sub-1-hour SLAs and 24/7 on-call coverage. Confirm the SLA in writing — “we respond quickly” is not a contractual commitment.

Hardware and Software Markups

MSPs typically markup hardware and software at 10–25% over distributor pricing. A $1,500 laptop through your MSP might run $1,700–$1,875. For companies buying 20+ devices per year, this adds $4,000–$10,000 annually in markup costs. Some MSPs allow you to buy direct if you provide proof of purchase — negotiate this into your contract if hardware volume is material.

Contract Lock-In and Switching Costs

Most MSP agreements run 12–36 months with 30–60 day cancellation notice requirements and early termination fees of 1–3 months of contract value. Switching MSPs also carries a transition cost: migrating documentation, RMM tooling, passwords, and vendor access to a new provider typically costs $5,000–$20,000 in billable migration hours. Don’t sign multi-year deals without a performance review clause.

What to negotiate before signing an MSP contract: Quarterly business reviews (QBRs) with written SLA performance data; hardware buy-direct allowance; a 90-day performance-out clause in year one; and a clear project rate card so out-of-scope billing has no surprises. For a full checklist of vendor contract red flags, see our IT vendor red flags guide.

Hidden Costs of In-House IT

The hidden cost trap with in-house IT is the skills gap. A single IT hire is physically incapable of being expert-level in every domain you need: help desk, networking, security, cloud infrastructure, compliance, vendor management, and strategic planning. You hire one person, assume they cover all of it, and discover the gaps when something breaks.

The Single-Point-of-Failure Problem

One IT person means zero coverage when they’re sick, on vacation, or exit the company. The average IT role has 13% annual turnover. When your IT person leaves, you face 60–90 days of reduced coverage while recruiting, plus $25,000–$75,000 in recruiting fees and lost productivity during transition. Companies that have experienced unexpected IT turnover consistently describe it as one of their most disruptive operational events — disproportionate to the role’s apparent scope.

Tool and Infrastructure Costs

In-house IT teams need the same monitoring, ticketing, endpoint management, and backup tools that MSPs use — you just pay retail instead of the wholesale rates MSPs negotiate. Remote monitoring and management (RMM) software: $1,200–$3,600/year. Endpoint detection and response (EDR): $2,000–$8,000/year for 50 seats. Ticketing system: $600–$2,400/year. Email security: $1,500–$5,000/year. Cloud backup: $2,000–$6,000/year. These tool costs add $8,000–$25,000 per year that never show up in the hiring budget.

Training and Certification Costs

IT certifications expire. Security landscapes evolve. A competent IT hire needs $2,000–$6,000/year in training and certification renewals to stay current. If you don’t fund this, their skills stagnate — and you either keep a deteriorating asset or fund the training that makes them more marketable and increases their likelihood of leaving.

Compliance and Security Exposure

Companies in regulated industries (healthcare, finance, legal) need security expertise that exceeds what a general IT hire brings. A single IT generalist managing HIPAA compliance or SOC 2 readiness is a liability risk. MSPs that specialize in regulated industries include compliance frameworks in their service delivery. The cost of a compliance gap — a breach, a failed audit, a regulatory fine — dwarfs the cost difference between hiring and managed services.

The true cost of in-house IT at 50 employees: $90,000 salary + $27,000 benefits (30%) + $12,000 tools + $4,000 training + $8,000 on-call/overtime = $141,000/year minimum. An MSP covering the same scope costs $45,000–$84,000. The gap funds significant business investment or is simply returned to the bottom line.

Decision Framework: Which Model Is Right for Your Company

The right IT model depends on four factors: company size, complexity, growth trajectory, and regulatory environment. Here’s how to map each to a recommendation.

Choose Managed IT if…
  • You have fewer than 75 employees
  • IT is a support function, not a competitive differentiator
  • You need 24/7 coverage but can’t afford 24/7 staff
  • Your team is distributed or remote-first
  • You’ve had IT turnover in the last 18 months
  • You’re in a regulated industry and need compliance expertise
  • Your infrastructure is predominantly cloud-based
Choose In-House IT if…
  • You have 150+ employees with stable headcount
  • IT is core to your product or operations (tech company, manufacturer)
  • You need on-site presence daily across multiple locations
  • You have complex, proprietary infrastructure that requires institutional knowledge
  • Security and compliance require a dedicated internal resource
  • You need deep business-context integration that an MSP can’t provide

The best answer for companies between 75 and 150 employees is usually a hybrid model: one internal IT director or manager for strategy, vendor relationships, and culture, plus an MSP for tier-1 help desk, 24/7 monitoring, and after-hours coverage. This captures the cost efficiency of managed services while adding the organizational alignment only an internal hire provides.

When to Switch: Managed IT to In-House (or Vice Versa)

The switch from managed to in-house IT is rarely driven by cost alone — it’s usually triggered by a combination of scale, complexity, and control. Here are the signals that indicate it’s time to evaluate a transition:

Frequently Asked Questions

How much does managed IT cost per month?

Managed IT typically costs $75–$200 per user per month for full-service coverage (help desk, security monitoring, patching, backups, and strategic guidance). For a 50-person company that’s $45,000–$120,000 per year. For 100 employees, expect $84,000–$156,000 per year. Per-user costs often decrease at higher volumes as MSPs negotiate bulk rates, so ask for tiered pricing during contract negotiations.

Is it cheaper to hire in-house IT or use a managed IT provider?

For most companies under 75 employees, managed IT is cheaper when you factor in total cost of employment (salary, benefits, PTO, training, turnover). One IT generalist costs $118,000–$160,000 per year fully loaded. An MSP covering the same ground costs $45,000–$84,000 for a 50-person team. In-house becomes more cost-competitive above 100 employees — especially when you need specialized skills that command premium salaries regardless of company size.

What are the hidden costs of in-house IT?

The biggest hidden costs are: (1) single point of failure risk when your IT person is sick, on vacation, or exits; (2) skills gaps — a generalist can’t be expert-level in security, networking, cloud, and help desk simultaneously; (3) recruiting and turnover at 13% average annual rate, costing $25,000–$75,000 per hire cycle; (4) tool licensing adding $8,000–$25,000/year for RMM, ticketing, EDR, and backup; and (5) overtime and on-call that isn’t budgeted in the base salary. For a deeper breakdown, see our hidden IT costs article.

What are the hidden costs of managed IT services?

Managed IT’s hidden costs include out-of-scope project billing at $150–$250/hour (budget 15–25% of annual MSP fee for projects); premium response time SLAs that cost 20–40% more than base contracts; hardware and software markups of 10–25% over retail; contract lock-in with 12–36 month terms and early termination fees; and MSP-to-MSP switching costs of $5,000–$20,000 when you change providers.

At what company size should you hire in-house IT instead of using an MSP?

The inflection point for most companies is 75–100 employees for the first in-house hire and 150–200 employees for a dedicated IT team. Below 75 employees, an MSP almost always delivers better coverage per dollar. Above 150 employees, the cost math often favors an internal team. The best model at 100–150 employees is often a hybrid: one internal IT manager for strategy, plus an MSP for tier-1 help desk and overnight monitoring.

Can you use both managed IT and in-house IT at the same time?

Yes — a hybrid model is common and often optimal for companies between 75 and 200 employees. The typical structure is one internal IT director or manager who handles strategy, vendor relationships, and escalations, while an MSP handles day-to-day help desk, monitoring, patching, and after-hours coverage. The key is a clear scope of work that defines who owns what — ambiguity between internal and external IT creates gaps and finger-pointing.
