How much an admin hire really costs
Between salary, Social Security, absenteeism and turnover, the real cost is 174 % of the gross. A full breakdown — and an alternative.
If you search "how much does an admin hire cost," the quick answer is: between €15,600 and €25,500 gross per year, depending on experience and region. The average salary for an administrative assistant in Spain is €17,500.
But that number isn't what it costs. It's what they earn. What it actually costs is a different figure — considerably higher, less visible, and with components most business owners never include in the calculation.
The salary of an admin hire is the visible part of the cost. The invisible part is nearly as large.
What the payslip says — and what it doesn't
Let's take a concrete example: €18,000 gross per year. 14 payments of €1,286. That's what the payslip says.
What the company pays that the payslip doesn't show: Social Security contributions of ~32 %. Common contingencies (23.6 %), unemployment (5.5 %), FOGASA (0.2 %), training (0.6 %), MEI (0.67 %), workplace accidents (~1.5 %). Total: €5,760 per year. The direct cost to the company is €23,760 — already 32 % more than the gross salary.
It's not a secret. But many business owners searching "how much does an admin hire cost" have never done this math.
For every euro of salary, the company pays 32 additional cents in Social Security. An €18,000 admin hire costs the company €23,760 before turning on the computer.
The costs nobody budgets for
Absenteeism — 22 days per year on average
Spain has the highest absenteeism rate in the EU, worsening 4.6 times faster than the European average. In 2024, the average Spanish worker missed 22 days per year — excluding holidays and public holidays. For a 3-person company, that means your only admin person is absent for nearly a month each year.
Holidays + public holidays — 36 days
22 working days of holiday plus 14 national, regional and local public holidays. Combined with absenteeism: around 58 days per year — 23 % of the working calendar — paid and not worked.
Turnover — a new person every two years
Turnover in administrative services is 49.6 %. Statistically, your admin hire will change companies every two years. And replacing them costs the equivalent of 100 % of their annual salary: recruitment, onboarding, and months of reduced productivity.
Workspace
Space, computer, software, supplies: between €2,700 and €6,400 per year depending on location.
49.6 % turnover in administrative services means that, statistically, you start from scratch every two years. And starting from scratch isn't free.
The full picture
| Item | Annual cost |
|---|---|
| Gross salary | €18,000 |
| Social Security (~32 %) | €5,760 |
| Direct absenteeism | ~€1,600 |
| Workspace + equipment + software | ~€3,000 |
| Recruitment (amortized over 2 years) | ~€1,000 |
| Onboarding / reduced productivity | ~€1,500 |
| Management overhead | ~€500 |
| Actual total | ~€31,360 |
The salary was €18,000. The real cost is €31,360 — 174 % of the gross. And that's without collective agreement extras, bonuses or benefits. For a half-time position: €15,000-16,000 per year in real terms, because many fixed costs don't scale linearly.
Who it makes sense for — and who it doesn't
1-3 people, under €300K revenue. Rarely justifiable. The owner absorbs the admin or pays an external accountant. The norm: spending 5-10 hours per week on it personally.
4-8 people, €300K-1M revenue. The pain point. Admin consumes 15-25 hours per week. It's often done by "whoever can" or a family member. The cost of having no one is real, but the cost of hiring is disproportionate.
9+ people, over €1M. Usually justifiable. The volume of invoices, suppliers and employees makes a dedicated person necessary — or several.
The reality of the Spanish business landscape: 81.6 % of companies have 2 or fewer employees — 2.7 million businesses. For them, hiring an admin means doubling or tripling the headcount.
For most Spanish businesses, hiring an admin isn't adding a resource. It's doubling the team.
Another way to access the function
Naia doesn't replace a person. It gives access to a function that most businesses can't afford.
If you don't have an admin team — and 85.8 % of Spanish freelancers have no employees — Naia is a way to start delegating that work for €300 per year. No Social Security. No holidays. No sick leave. No turnover. Fully auditable, available 24/7, with no commitment beyond the month you pay for.
If you already have a team, Naia doesn't replace them — it amplifies them. The lower-value tasks — recording received invoices, matching payments, preparing documentation for the accountant — Naia handles those. Your team focuses on what people do better than any system: relationships, judgment, negotiation, context.
It's not a question of person versus machine. It's a question of access to a function that today, for most businesses, is out of reach.
The alternative to an admin hire isn't a cheaper person. It's the admin function existing without needing a dedicated person.
