The true cost of a system administrator

Note on salary data: The figures below are based on the French job market (2024-2026). In France, employer contributions add approximately 45% on top of gross salary. While exact numbers vary by country, the cost ratio between hiring in-house vs outsourcing remains comparable internationally.

Average sysadmin salaries in France (2024-2026)

Level Gross salary/year Employer contributions (~45%) Total employer cost
Junior (0-2 years) 38,000 EUR +17,100 EUR 55,100 EUR
Mid-level (3-5 years) 50,000 EUR +22,500 EUR 72,500 EUR
Senior (5-8 years) 65,000 EUR +29,250 EUR 94,250 EUR
Expert / Lead (8+ years) 75,000 EUR +33,750 EUR 108,750 EUR

Hidden costs of hiring

Recruitment: 3,000 to 10,000 EUR (agency fees, job ads, time spent)
Training: 2,000 to 5,000 EUR/year (certifications, courses)
Tools & licences: 1,000 to 3,000 EUR/year (software, subscriptions)
Turnover: 6-9 months of salary if they leave (very common in IT)

In France, a senior sysadmin costs approximately:

~7,900 EUR / month

(94,250 EUR / 12 months, excluding hidden costs)

And 24x7 on-call support? That costs extra!

A salaried sysadmin works 35-40 hours/week. Who responds at night? On weekends? On public holidays?

For reliable 24x7 on-call support in-house:

  • -- 4 people minimum in rotation (to cover leave, sick days)
  • -- On-call compensation: ~3,500 EUR/month (see the detailed breakdown)
  • -- Total: ~11,400 EUR/month for one sysadmin + on-call coverage

Our managed services include 24x7x365 on-call support in the package.

Managed Services vs 1 Full-Time Sysadmin

Comparison basis: 1 senior sysadmin = 7,900 EUR/month (140h/month capacity)

Package Hours included Monthly price vs 1 FTE
1 server 1h/month 150 EUR -98%
5-server pack 2h/month 600 EUR -92%
10-server pack 3h/month 900 EUR -89%
20-server pack 5h/month 1,600 EUR -80%

All packages include:

  • -- 24x7x365 on-call, 4h response time SLA
  • -- Monitoring & alerting
  • -- Security updates

Additional hours:

  • -- 120 EUR/h (billed per half-hour)
  • -- Pooled across your fleet

In practice:

Unless you run a highly technical stack, 5h/month for 20 servers is generally more than enough.

You handle the "build"? We cover the 24x7.

Already have a sysadmin who designs architecture and manages projects during the day? Combine 1 FTE (7,900 EUR) + outsourced on-call (3,450 EUR) = 11,350 EUR/month for 140h of capacity + 24x7 coverage.

Fleet on-call, 4h response time SLA

3,450 EUR/month - 24x7x365 coverage

Fleet on-call, 1h response time SLA

6,000 EUR/month - Guaranteed intervention within 1h

The real calculation

20-server pack (1,600 EUR): Still cheaper than one FTE (7,900 EUR), even with only 5h included. Need more hours? Even at 20h/month extra (2,400 EUR), you stay at 4,000 EUR -- half the cost of a full-time hire.

100% in-house 24x7? You need 4 sysadmins = 4 x 7,900 EUR = 31,600 EUR/month for 640h of capacity. Do you really need that much?

Beyond cost: other advantages

Multidisciplinary team

A single sysadmin cannot master everything. With managed services, you get access to a complete team (systems, networking, security, databases).

Guaranteed availability

No holidays, no sick leave, no surprise resignations. Managed services ensure permanent service continuity.

Instant scalability

Need to add 5 servers? No need to hire. Managed services scale with your growth without delay.

No single point of failure

No more "bus factor". If your sysadmin leaves, they take their knowledge with them. With us, documentation and procedures are shared across the team.
