In a 20-workstation company, one hour of IT downtime costs around €1,000 in our example, and almost two thirds of that is lost revenue, not salaries. A morning without the server, internet or email easily exceeds €3,500. We show the calculation step by step, using official data, so you can repeat it with your company’s own figures and decide how much to invest in prevention.
The key figures
- Around €14 per person per hour In pay and employer social security alone, using Statistics Portugal’s (INE) average salary for 2025.
- Around €1,000 per hour In a 20-workstation company, adding salaries, lost revenue and recovery.
- Around €3,560 For a failure at 9:00 am resolved by lunchtime, four hours later.
- More than €7,000 a year If that lost morning happens twice.
And these figures still leave out what is hardest to measure: the client who gave up, the missed deadline and the team sitting idle in front of the screen.
Where the cost of each hour comes from
Downtime hits in three ways, which together give the real cost:
- Salaries without output — people are still paid but cannot work: number of people idle × hourly cost of each.
- Revenue that does not come in — sales, bookings or appointments that do not happen; some is recovered later, some is lost.
- Recovery time — when systems come back, there are emails piling up, work to redo and clients to call back.
An important clarification: an employee’s hourly cost is not the salary divided by the hours. It is everything the company pays in a year — salary, statutory bonuses and employer social security — divided by the hours actually worked.
The cost of one idle person, using INE data
According to INE, average total gross monthly pay per employee in Portugal was €1,694 in 2025, already including bonuses and other irregular components spread across the year. Over 12 months, that is around €20,330 gross.
Adding the employer’s social security contribution (TSU) of 23.75% in most cases, the annual cost reaches around €25,160. With 220 effective working days (excluding weekends, 22 working days of holiday and public holidays) at 8 hours a day, that is 1,760 hours.
Result: €25,160 ÷ 1,760 h = around €14.30 per hour per person. That is the minimum. In offices, clinics and service companies, where salaries are usually above average, the figure rises.
Cost table by company size
Assumptions, in round numbers that are easy to replace:
- Revenue €100,000 per employee per year (use annual revenue ÷ number of people).
- Unrecoverable revenue 50% of what was not done in that hour.
- Recovery 30 minutes per person after systems come back.
- Total outage Nobody can work.
| Workstations | Salary cost (1 h) | Lost revenue (1 h) | Recovery (30 min) | Total per hour |
|---|---|---|---|---|
| 10 | €143 | €284 | €71 | ≈ €500 |
| 20 | €286 | €568 | €143 | ≈ €1,000 |
| 30 | €429 | €852 | €214 | ≈ €1,500 |
| 60 | €858 | €1,705 | €429 | ≈ €3,000 |
Illustrative example. Salary cost based on INE average pay (2025) and employer social security of 23.75%; revenue and recovery are assumptions to adjust.
Costs the table does not show
The example is deliberately conservative. On a bad day, these costs can outweigh all the others:
- Lost data If the cause is a disk failure or an attack and the backup does not work, the outage goes from hours to days.
- Reputation A hotel without network at check-in or a clinic unable to take appointments is noticed by the client immediately.
- Penalties Missed contractual deadlines with your own clients.
- Overtime To catch up.
- Legal obligations Incidents involving personal data may require notification and, in some sectors, fall under the NIS2 directive.

How an MSP reduces the cost of downtime
Detect before it stops
Almost all outages give warning: a disk accumulating errors, a UPS at the end of its battery life, a line dropping packets, a certificate about to expire. With NOC and proactive monitoring, the alert reaches an engineer before it reaches users. The difference is explained in proactive monitoring or reactive support.
Shorten the outage with redundancy
A second internet connection that takes over automatically when the main one drops, backups actually restored in testing, and a written plan of who does what in the first hour. That is what separates 15 minutes from an entire day. See how we design business continuity and disaster recovery.
One accountable party with contracted response times
With response times defined in the contract, the question “who do I call?” is answered before the problem arises. In IT Unlimited managed services, support is remote, on-site and by telephone, with immediate response times. For those who cannot stop out of hours, the Premium 365 tier adds nights, weekends and public holidays, and is the only one with 24/7 support and monitoring.
Real case: Boost Portugal cannot be without internet
Boost Portugal, a tourism activities company operating in Lisbon, Porto, the Douro and Madrid, has DataRoad as its IT partner under an IT Unlimited contract. It sells experiences to tourists on the spot: without internet, it stops selling.
The solution combines internet redundancy with automatic failover, remote monitoring with alerts and availability reports, backups and support for the IP phone system. Read the Boost Portugal case.
Frequently asked questions
How do I calculate the cost of one hour of downtime in my company?
Add the hourly cost of the idle people (annual cost of salary and social security ÷ hours worked), the revenue from that hour that cannot be recovered and the recovery time. Using the INE average, the salary cost is around €14 per person per hour.
What if only one system fails?
Apply the calculation only to the people affected and to the revenue that depends on that system. This is where a lot of cost hides: small, frequent failures that nobody records.
How much does it make sense to invest in prevention?
Compare the annual cost of likely outages with the cost of prevention. Two lost mornings a year already justify monitoring, redundancy and tested backups.
Does DataRoad offer 24/7 support?
24/7 support and monitoring are exclusive to Premium 365. Essential and Premium cover business hours, with immediate response times.
