IT Decision Guide · 2026
The question isn't which is cheaper on paper — it's which provides the coverage your business actually needs at a cost you can justify. Here's the decision framework that answers that for your specific situation.
For companies under 75 users, an MSP almost always provides more coverage per dollar than in-house IT. Between 75–200 users, it depends heavily on complexity and compliance requirements. Above 200 users, a hybrid model — an internal IT director + MSP execution — typically outperforms either pure option. The deciding factor is rarely cost alone.
Most cost comparisons between MSP and in-house IT undercount what an internal IT person actually costs. The fully-loaded cost includes more than salary:
| Cost Component | Annual Cost (US Median) |
|---|---|
| Base salary (IT generalist, 3–7 years experience) | $75,000–$95,000 |
| Payroll taxes (employer share, ~8%) | $6,000–$7,600 |
| Benefits (health, dental, vision) | $8,000–$14,000 |
| 401k match (3%) | $2,250–$2,850 |
| Training and certifications | $2,000–$5,000 |
| Equipment (laptop, peripherals, software) | $3,000–$5,000 |
| Recruiter fee (amortized over 2-year tenure) | $5,000–$10,000 |
| Total fully-loaded cost | $101,250–$139,450 |
At 50 users, this translates to $169–$232 per user per month — before accounting for PTO coverage, after-hours incidents, and the specialized skills your IT generalist doesn't have.
An IT generalist can handle the day-to-day efficiently: helpdesk tickets, device management, onboarding, vendor coordination. But no single person has deep expertise across every domain a modern business IT environment requires:
| Domain | In-House Generalist | MSP Team |
|---|---|---|
| Helpdesk / day-to-day support | ✓ Strong | ✓ Strong (shared pool) |
| Network infrastructure | Basic to moderate | ✓ Specialist available |
| Cybersecurity / EDR / SOC | Limited (not their specialty) | ✓ Dedicated security team |
| Compliance (HIPAA, CMMC, SOC 2) | Rarely their background | ✓ Compliance specialists |
| After-hours / weekend coverage | On-call (burns out fast) | ✓ 24/7 coverage |
| Knowledge continuity if person leaves | ✗ Key-person risk | ✓ Team-based documentation |
| Vendor-specific platform expertise | Varies | Varies (ask specifically) |
| Scalability during growth | Breaks at capacity | ✓ Scales with contracts |
The most underestimated risk of single-person in-house IT is not the cost — it's the fragility. When your IT person is out:
According to SerenIT's 2026 benchmarks, the average IT staff tenure at companies under 100 employees is 2.3 years. The average transition period when an in-house IT person leaves is 3.2 months of degraded IT coverage. For a 50-person business, that transition risk alone can justify the premium of a managed service over in-house staff.
In-house IT is the right choice when:
An MSP is typically the better choice when:
For companies between 75–300 users, the hybrid model often outperforms either pure option: an internal IT director or manager who provides strategic direction, vendor management, and institutional knowledge — supported by an MSP for execution, security operations, and specialized skills.
This structure works because it separates the roles that genuinely require embedded employees (strategy, business alignment, vendor accountability) from the roles that benefit from scale and specialization (security monitoring, helpdesk depth, compliance expertise).
Use these questions to clarify which model fits:
1. What's your user count and is it stable or growing? Under 50 users: MSP. 50–150 with stable growth: MSP or hybrid. 150+ with rapid growth: hybrid or in-house.
2. Do you have compliance requirements beyond standard baseline security? If yes (HIPAA, CMMC, FINRA, FTC Safeguards), a specialist MSP or hybrid model almost always outperforms a generalist in-house hire.
3. How would you handle a critical IT failure at 11pm on a Friday? If you don't have a good answer, your current model has a gap — whether in-house or MSP.
4. What happens to IT if your current person leaves? If the answer is "we'd be in serious trouble," that's key-person dependency — a structural risk that should influence your model decision.
At what company size does in-house IT make more sense than an MSP?
There's no universal threshold, but the inflection point for most businesses is around 75–150 users with complex, specialized environments. Below that, an MSP almost always provides more coverage per dollar. Above 200 users with significant compliance obligations, a hybrid model typically outperforms either pure option.
What does an in-house IT person actually cost?
A fully-loaded in-house IT generalist costs $101,000–$139,000 per year in most US markets (salary, taxes, benefits, training, equipment, recruiting). This covers one person who works 40 hours per week — with no coverage for nights, weekends, illness, or vacation.
Can I switch from in-house IT to an MSP without disrupting my business?
Yes, with proper planning. The key is documentation: before your in-house person transitions out, ensure all credentials, configurations, vendor contacts, and infrastructure documentation are captured and transferred to the incoming MSP. A 4–8 week parallel overlap period is standard practice for a clean transition.
What's the real risk of relying on a single in-house IT person?
Key-person dependency: when your IT person is sick, on vacation, or gives notice, your entire IT function degrades. Secondary risks include knowledge concentration, skill ceiling limitations, and no after-hours coverage without burning out the individual.
