The question surfaces at every stage of company growth: should we hire an IT person, or contract a managed service provider? At 15 employees, it feels premature to hire. At 40 employees, the pain of having no dedicated IT is real. At 80 employees, you're wondering if the MSP you hired at 30 employees is still the right fit.
The challenge is that most businesses make this decision based on the most visible number — either the MSP's monthly invoice or the job posting salary. Neither tells you what you need to know. The real comparison is fully loaded MSP cost versus fully loaded in-house cost: salary plus benefits plus training plus tools plus the structural limitations of each model at your specific headcount.
This guide gives you that comparison. We'll cover the true cost of each model at three company sizes (10–50, 50–200, and 200–500 employees), how to analyze the break-even point for your situation, which functions are better outsourced versus kept in-house, and how to evaluate whether a specific MSP is worth the price they're asking. The goal is a decision you can defend with numbers, not just a gut feeling.
Average fully loaded annual cost of a single mid-level IT generalist in a mid-tier US market — including salary ($78K–$88K base), employer taxes, health insurance, 401(k) match, paid time off, and recruiting costs. Most SMBs budget for salary only and are surprised by the 40–55% overhead multiplier. This is the number you need to beat — or match with better coverage — to justify an MSP contract.
What You're Actually Comparing
Before running the numbers, it's worth being precise about what each model actually provides — because the comparison only holds if the scope of services is equivalent.
A managed service provider (MSP) is an outsourced IT department that delivers a defined set of services under a recurring contract. Typical MSP scope for SMBs includes: helpdesk support for end users, endpoint management (laptops, desktops, mobile devices), patch management and software updates, backup monitoring and testing, network monitoring, security alerting, and vendor escalations on your behalf. MSPs staff these services with teams of technicians — you get collective expertise across multiple specialties, not the skill set of a single person.
In-house IT means employing one or more people whose full-time job is managing your technology environment. The scope of what they cover is theoretically everything — helpdesk, infrastructure, vendor management, strategic planning, projects, security — but the practical reality is that one person's capacity and knowledge has hard limits. An IT generalist at 70 employees is handling reactive tickets, keeping the lights on, and not doing much strategic work.
The comparison gets complicated because the two models serve different needs at different scales — and the right answer often isn't binary. A third option exists: the co-managed or hybrid model, where you have an internal IT person working alongside an MSP that handles specific functions. We'll cover this in detail, but keep it in mind as we work through the pure-play comparison.
The True Cost of an In-House IT Hire
The most common mistake SMBs make when evaluating in-house IT is treating base salary as the total cost. It isn't. The fully loaded cost of a US employee — including mandatory employer costs, benefits, and overhead — runs 40–55% above base salary. Here's what that means in practice for IT hires at different experience levels.
IT Salary Ranges by Role and Market
| Role | Mid-tier Market Base | Major Metro Base | Typical Scope |
|---|---|---|---|
| IT Support Specialist | $45,000–$60,000 | $55,000–$75,000 | Helpdesk, tier 1–2, basic endpoint mgmt |
| IT Generalist / Systems Admin | $70,000–$90,000 | $90,000–$120,000 | Full SMB IT: infrastructure, helpdesk, vendor mgmt |
| Senior Sysadmin / IT Manager | $90,000–$115,000 | $115,000–$155,000 | Strategy, team leadership, complex infrastructure |
| IT Director / VP of IT | $110,000–$145,000 | $145,000–$200,000+ | Org-wide strategy, budget ownership, executive alignment |
The Fully Loaded Cost Breakdown
For an IT generalist at $80,000 base salary in a mid-tier US market, here's the actual annual cost to the business:
$80,000 Base Salary — Annual True Cost
| Cost Component | Annual Amount | Notes |
|---|---|---|
| Base salary | $80,000 | Mid-level IT generalist, mid-tier market |
| FICA (employer share) | $6,120 | Social Security (6.2%) + Medicare (1.45%) |
| Health insurance (employer share) | $8,400 | $700/mo employer contribution; varies widely |
| 401(k) employer match | $3,200 | 4% match on full salary |
| Paid time off (15 days) | $4,615 | Salary cost of ~3 weeks of paid leave |
| Training and certifications | $2,500 | Annual training budget; IT roles require ongoing cert maintenance |
| IT tools and licenses | $6,000 | RMM, ticketing system, documentation, security tools |
| Recruiting and onboarding | $4,000 | Amortized over 3-year average tenure |
| Fully Loaded Annual Cost | $114,835 | 44% overhead on base salary |
This model excludes dental/vision, life insurance, unemployment insurance (FUTA/SUTA), and any hardware (laptop, desk, monitors) for the IT person themselves. Full-benefit packages in competitive markets often push this number to $125,000–$135,000.
The other critical limitation of a single in-house hire: they can only be in one place, doing one thing, during business hours. When they're on vacation, sick, or leave for another job, you have a coverage gap. When an issue is outside their expertise — a complex network failure, a security incident, a cloud migration — you either wait for them to learn it or pay for outside help anyway.
The True Cost of an MSP
MSP pricing is less transparent than it should be. The monthly invoice is clear; what's included (and excluded) often isn't until you need something that falls outside scope. Understanding MSP pricing models and typical cost structures helps you compare apples to apples.
MSP Pricing Models
MSPs price their services in three primary ways:
- Per-user pricing ($100–$200/user/month for SMB full management): Covers all services for each employee regardless of how many devices they use. Scales predictably as you hire. Most transparent for budgeting.
- Per-device pricing ($30–$80/device/month): Covers each endpoint — laptop, desktop, server. Can be cheaper than per-user if employees share devices or have simple environments; can be more expensive if employees have multiple devices.
- Flat-rate "all you can eat" ($2,000–$8,000/month for 25–75 users): Fixed monthly fee for all services within a defined scope. Simpler invoicing but scope ambiguity becomes costly — what counts as an "extra" project?
For most SMBs, per-user pricing is the most common and the most straightforward to compare. At $150/user/month (mid-market SMB rate), here's what the annual cost looks like by company size:
| Company Size | MSP @ $100/user/mo | MSP @ $150/user/mo | MSP @ $200/user/mo |
|---|---|---|---|
| 25 employees | $30,000/yr | $45,000/yr | $60,000/yr |
| 50 employees | $60,000/yr | $90,000/yr | $120,000/yr |
| 100 employees | $120,000/yr | $180,000/yr | $240,000/yr |
| 200 employees | $240,000/yr | $360,000/yr | $480,000/yr |
The scope exclusion trap: MSP contracts define covered services, and anything outside scope is billed separately — often at $125–$200/hour. Common exclusions that generate surprise invoices: new equipment setup beyond routine onboarding, office relocations, application migrations, custom scripting, and any "project work" over a defined time threshold (often 2–4 hours). Read the statement of work before you sign, not after you get the first out-of-scope invoice.
Break-Even Analysis by Company Size
The break-even point is where the cost of an MSP equals the fully loaded cost of equivalent in-house coverage. But "equivalent coverage" is the hard part — an MSP brings collective expertise, 24/7 monitoring, and bench depth that one person cannot match. The comparison isn't just cost; it's cost for comparable service quality.
10–50 Employees: MSP Almost Always Wins
At this stage, your IT needs are real but don't justify a full-time hire. The work is episodic — new hire setup, vendor issues, password resets, the occasional outage — not continuous. A full-time IT generalist at this scale spends 40–60% of their time waiting for work that doesn't materialize, and the fully loaded cost of $110,000–$130,000/year is hard to justify against 15–40 hours per month of actual IT demand.
MSP vs In-House IT at 30 Users
| Model | Annual Cost | Coverage Profile | Coverage Gaps |
|---|---|---|---|
| MSP @ $150/user/mo | $54,000 | Helpdesk, endpoint mgmt, patch, backup monitoring, 24/7 alerts | Limited strategic IT; project work billed extra |
| In-house IT generalist | $115,000–$130,000 | Full scope, deep business context, strategic input | Vacation/sick coverage, specialist knowledge gaps, single point of failure |
| Part-time IT contractor | $25,000–$45,000 | Scheduled on-site hours, break-fix, projects | No proactive monitoring, poor availability for urgent issues, no helpdesk |
Verdict: MSP delivers meaningful cost advantage at this stage — typically 50–65% less than a full-time hire with comparable day-to-day coverage. The tradeoff is less institutional knowledge and slower turnaround on complex issues. For most businesses under 40 employees, this is the right tradeoff.
50–200 Employees: The Convergence Zone
This is where the decision gets genuinely complex. At 50–100 employees, your IT demand is substantial enough that a full-time hire is justified — but the MSP still brings coverage advantages that one person cannot replicate. At 100–150 employees, a single generalist is fully utilized and starting to struggle with the breadth of work. At 150–200, you're approaching a point where a two-person in-house team may deliver more value at lower cost than a full-service MSP.
MSP vs In-House IT at 100 Users
| Model | Annual Cost | What You Get |
|---|---|---|
| MSP @ $150/user/mo | $180,000 | Helpdesk team, 24/7 monitoring, patch mgmt, security alerting, specialist escalation bench |
| One IT generalist (fully loaded) | $115,000–$130,000 | Full owner of IT environment; no after-hours coverage, no bench depth, vacation leaves gap |
| One generalist + MSP helpdesk supplement | $145,000–$165,000 | Internal owner for strategy/projects + MSP handles tier 1 volume and after-hours |
| Two-person in-house team | $200,000–$250,000 | Coverage redundancy, deeper ownership, but still limited specialist depth |
Verdict: At 100 employees, a single in-house hire is cheaper than a full-service MSP on paper — but the coverage model is weaker. The co-managed option (one internal person plus supplemental MSP services) often wins on both cost and coverage at this stage.
200–500 Employees: In-House Starts to Win on Economics
At this scale, your IT complexity has grown in ways a standard MSP contract may not handle well: multiple office locations, complex compliance requirements, custom applications, ERP systems, and a growing number of integrations. MSP costs at $150/user/month are running $360,000–$900,000/year — approaching the cost of a small dedicated IT team with significantly more institutional knowledge and business alignment.
MSP vs In-House IT Team at 250 Users
| Model | Annual Cost | Pros | Cons |
|---|---|---|---|
| Full-service MSP @ $150/user/mo | $450,000 | Breadth of specialists, 24/7 coverage, no management overhead | Low business context, project work billed separately, vendor-managed tools |
| In-house team: IT Manager + 2 techs | $320,000–$380,000 | Deep business alignment, strategic input, no scope exclusions | Coverage limits on after-hours and specialist depth; hiring/retention risk |
| In-house IT Manager + MSP for helpdesk/monitoring | $275,000–$330,000 | Best of both: strategic ownership inside, operational coverage outside | Requires clear scope delineation; coordination overhead between teams |
Verdict: At 250 employees, a hybrid model (internal IT lead with MSP for operational services) typically delivers the lowest cost with the strongest coverage profile. A pure MSP at $450K/year is approaching the cost of a strong in-house team, without the business context benefits of dedicated staff.

Take the Free Assessment →The Hybrid Model: What to Outsource vs Keep In-House
The binary framing of "MSP or in-house" misses the most common optimal answer for mid-size businesses: a hybrid model where specific functions are deliberately outsourced while others remain internal. The key is being deliberate about which functions belong where — not arriving at hybrid by accident because the pure-play options didn't work.
Functions Better Handled by an MSP
- Tier 1 helpdesk: Password resets, software installs, connectivity issues, printer problems — high volume, low complexity, best handled by a team with capacity and documented runbooks. An in-house IT person spending 40% of their time on tier 1 tickets is an expensive ticket-closer.
- 24/7 monitoring and alerting: Infrastructure monitoring, security event alerting, backup verification — these need to be continuous and responded to at 2am. MSPs staff for this; individuals can't.
- Patch management and endpoint compliance: Routine, process-driven, benefits from specialized RMM tooling that MSPs amortize across their client base. Doing this well in-house requires tool investment and discipline that small teams often don't maintain consistently.
- Specialist depth on call: Network engineering, security incident response, cloud architecture — work that arises occasionally but requires deep expertise when it does. MSPs staff these specialists; hiring them full-time rarely pencils out below 500 employees.
Functions Better Kept In-House
- IT strategy and planning: Technology decisions need to be made by someone who understands your business goals, not a vendor with a service catalog. Roadmap development, vendor evaluation, and budget planning require business context that external providers rarely develop.
- Application ownership: Your CRM, ERP, custom software, and business-critical integrations need an owner who understands how the business uses them. MSP contracts typically exclude application-specific support beyond basic connectivity.
- Vendor management and negotiation: Someone on your side needs to own vendor relationships, contract renewals, and escalations. When an MSP manages your vendors, their incentives aren't always aligned with your cost optimization goals.
- Security governance: Policies, access control reviews, security awareness training, and compliance reporting should be owned internally. MSPs can execute operational security tasks, but security governance is a leadership function, not a service.
- Executive and board-level IT representation: Technology risk, investment decisions, and digital strategy belong in internal hands. An MSP account manager is not a CISO or CTO equivalent.
The co-managed sweet spot: For companies with 75–300 employees, the most cost-effective model is typically a single internal IT lead (IT Manager or Director level) who owns strategy, vendors, applications, and security governance — paired with an MSP handling tier 1 helpdesk, 24/7 monitoring, patch management, and specialist on-call access. This model typically costs 15–30% less than a pure MSP at equivalent scale while delivering significantly better business alignment. See our guide to choosing a managed IT provider for criteria to evaluate MSPs specifically for co-managed arrangements.
MSP Evaluation Criteria
Not all MSPs are equivalent. The difference between a strong MSP and a weak one at $150/user/month is not visible in the pricing — it's visible in how they handle an incident at 11pm, whether they proactively identify problems before they become outages, and whether their technicians understand your environment after six months or still rely on documentation to answer basic questions.
What to Evaluate Before You Sign
Response and resolution SLAs. A good MSP commits to specific response and resolution times with financial teeth — service credits if SLAs are missed. "Best effort" SLAs without credits are not SLAs. For a standard business, reasonable SLAs are: critical issues (systems down) 15–30 minute response, 4-hour resolution; high (major degradation) 1-hour response, 8-hour resolution; normal (single user affected) 4-hour response, 24-hour resolution.
Technician assignment model. Ask specifically: will we have a dedicated technician or team, or will our tickets go into a general pool? Dedicated technician models develop institutional knowledge about your environment. Pool models mean you explain the same context every time you call. The difference in support quality is significant over a 12-month engagement.
Security stack specifics. Verify what's actually included in the security component of your MSP contract. At minimum, an MSP should be deploying: endpoint detection and response (EDR) on all managed devices, email security filtering, multi-factor authentication enforcement, and security awareness training. "Security is included" often means legacy antivirus only — ask for the specific tool names and coverage scope.
Tooling ownership and portability. MSPs deploy their own RMM (remote monitoring and management) agents, backup software, and sometimes endpoint security tools. When you leave, what happens to your data, configurations, and documentation? The best MSPs provide complete data exports and transition assistance as a contractual commitment. An MSP that stonewalls on this question during the sales process is showing you how the offboarding conversation will go.
Contract terms and exit provisions. As with any vendor contract, the terms you agree to at signing determine your leverage for the next 1–3 years. Push for annual contracts (not multi-year), 30–60 day termination notice (not 90–180 days), a clear definition of what constitutes "project work" versus included services, and a price cap on year-over-year rate increases. See our guide on negotiating IT vendor contracts for exact language to request.
MSP Red Flags: When to Walk Away
The MSP market has a wide quality distribution. These are the warning signs that a specific provider is likely to disappoint:
- Vague SLAs with no financial remedy — "We aim to respond within X hours" is not an SLA. If there's no service credit structure, there's no accountability mechanism.
- Bundled cybersecurity with no specifics — Ask which EDR platform they deploy. If the answer is vague ("we use industry-leading security tools"), that usually means legacy AV. Insist on named products and ask to see a sample security report.
- Proprietary backup and RMM with no portability commitment — Your data and configurations should be yours. Any MSP that refuses to commit in writing to providing your data upon termination is building lock-in by design.
- No dedicated technician on your account — Pool support models are efficient for the MSP; they're frustrating for you. Ask explicitly who will know your environment.
- Auto-renewal clauses with long notice periods — 90-day or 180-day termination notice with auto-renewal is designed to trap you. Annual contracts with 30–60 day notice are reasonable; longer is a red flag.
- All-inclusive pricing with an unusually broad "project work" carve-out — If any work over 2 hours is "project work" billed at $150+/hour, the flat-rate pricing is an illusion. Quantify your typical project volume before signing.
- References that are all small accounts — Ask for references from clients at your size or larger, in your industry if possible. An MSP that exclusively serves 5-person businesses may not have the operational depth for a 100-person environment.
The MSP vs In-House IT Decision Matrix
Use this weighted scoring matrix to evaluate your specific situation. Score each dimension 1–5, multiply by the weight, and sum the totals for each model. The model with the higher weighted score is better suited to your current situation — with the understanding that the right answer changes as you grow.
Score 1–5 for Each Model (5 = Clear Advantage)
| Dimension | Weight | MSP Score (1–5) | In-House Score (1–5) | Scoring Guidance |
|---|---|---|---|---|
| Annual cost at current headcount | 25% | ___ | ___ | Use fully loaded costs from tables above. 5 = 20%+ cheaper; 1 = 20%+ more expensive |
| Coverage breadth required | 20% | ___ | ___ | Score MSP high if you need 24/7 coverage, specialist depth; in-house high if you need deep business context |
| IT complexity and growth trajectory | 15% | ___ | ___ | MSP scales headcount easily; in-house scales knowledge better for complex, custom environments |
| Security and compliance requirements | 15% | ___ | ___ | Score MSP high if security tools and compliance reporting are included; in-house high if you need dedicated security ownership |
| Availability of qualified local IT talent | 10% | ___ | ___ | In-house is harder to score well in tight labor markets; MSP availability is geography-independent |
| Strategic IT leadership needs | 10% | ___ | ___ | In-house wins if you need IT at the leadership table; MSP wins if operations is the primary need |
| Risk tolerance (single point of failure) | 5% | ___ | ___ | MSP eliminates single-person dependency; in-house creates it unless you build a team |
Multiply each score by its weight percentage, then sum. A weighted total above 3.5 for either model represents a clear preference. If the scores are within 0.3 of each other, the co-managed hybrid model is likely worth evaluating — it often threads the needle when neither pure-play option dominates.
Making the Final Call
The numbers matter, but a few structural questions should anchor your decision before you run any spreadsheet:
Are you buying IT operations or IT leadership? MSPs provide operations — tickets resolved, endpoints managed, patches applied. If what you actually need is someone to own your technology strategy, evaluate your vendors, represent IT at leadership meetings, and build the systems that support your growth — a single in-house hire with genuine strategic authority typically delivers more value than an MSP, regardless of cost comparison. If what you need is reliable operations without the management overhead of an employee, MSP wins.
What is your growth rate? If you're planning to double headcount in 18 months, an MSP offers predictable, linear cost scaling. Building an in-house team during rapid growth means recruiting, onboarding, and managing IT staff while everything else is also scaling — a real distraction cost that doesn't show up in salary comparisons.
What does your tech environment look like? Standard cloud-first environments (Microsoft 365, cloud-hosted SaaS, no on-premise servers) are MSP-friendly — the management surface is well-understood, and MSPs have mature tooling for it. Complex legacy environments, custom applications, on-premise infrastructure, or regulated data handling often benefit from the deeper ownership model that in-house staff provides.
Where are you geographically? In major metros with competitive IT labor markets, in-house hiring is expensive and talent retention is difficult. MSPs often represent better value in high-labor-cost markets than the national average suggests. In secondary markets where MSP coverage is thinner and IT labor is more affordable, in-house hiring becomes relatively more attractive.

Frequently Asked Questions
How much does a managed service provider cost per month?
MSP pricing for small and mid-size businesses typically runs $100–$200 per user per month for full managed services — helpdesk, endpoint management, patch management, backup monitoring, and basic security. At $150/user/month, a 50-person company pays $7,500/month ($90,000/year). Some MSPs price per device ($30–$80/device/month) instead of per user. Prices at the high end ($175–$200+) usually include bundled cybersecurity (EDR, email security, security awareness training). Always verify what's in scope — especially whether project work, after-hours support, and application-specific support are included or billed separately.
What is the fully loaded cost of an in-house IT hire?
A mid-level IT generalist in a mid-tier US market commands $70,000–$90,000 in base salary. Add employer-side costs — FICA (7.65%), health insurance, 401(k) match, PTO, training, and tools — and the fully loaded annual cost runs $95,000–$130,000. In major metro markets, add 20–40% to base salary. Most SMBs underestimate this by 30–40% by budgeting only for salary. The fully loaded cost is the right number to use when comparing against an MSP invoice.
At what company size does in-house IT become cheaper than an MSP?
The break-even varies by MSP pricing and labor market, but a general guideline: under 50 employees, an MSP at $100–$150/user/month almost always beats a full-time hire on cost. At 75–100 employees, the costs converge — a single in-house hire may be cost-competitive with an MSP but provides weaker coverage. Above 150 employees, a single in-house generalist typically covers the workload at lower cost than MSP fees, though coverage gaps remain. At 250+ employees, a small in-house team (2–3 people) usually beats MSP pricing while providing better institutional knowledge.
What should be in a managed IT service agreement?
A solid MSP agreement should specify: response and resolution SLAs with financial penalties for misses; a complete list of covered services (and explicit exclusions for project work); the security tools deployed on your behalf (by name, not category); data portability and export rights at termination; a defined account team or dedicated technician; price escalator caps for renewal periods; and termination notice requirements (30–60 days is reasonable; 90+ days is a red flag). Vague "best effort" language in any of these areas is a contract problem, not a minor drafting issue.
What is co-managed IT and when does it make sense?
Co-managed IT pairs an internal IT person with an MSP that handles specific functions — typically tier 1 helpdesk, 24/7 monitoring, and patch management. The internal person owns strategy, vendor management, application support, and complex projects. This model works well for companies with 75–300 employees: you get deep business context from an internal owner plus breadth and coverage from the MSP. It typically costs 15–30% less than a pure MSP at equivalent scale. The key to making it work is clear scope delineation — ambiguity about who handles what creates gaps and finger-pointing during incidents.
