Why Senior Contractors Charge €70-€120 per Hour

by Eric Hanson, Backend Developer at Clean Systems Consulting

The First Reaction

The first time you see it, it feels off.

€90 per hour? €120? For one developer?

It’s natural to compare that to a monthly salary and think: this doesn’t make sense. But that comparison misses the point.

You’re thinking in hours. Senior contractors think in outcomes.


You’re Not Paying for Time

Here’s the shift that changes everything:

You’re not paying for the hours. You’re paying for how few of them are needed.

A senior contractor has already seen the common traps:

  • fragile architecture
  • hidden edge cases
  • scaling issues waiting to happen

So instead of:

  • days of trial and error
  • multiple rewrites
  • “we’ll fix it later” decisions

You get:

  • a clear approach
  • fewer iterations
  • something that actually works in production

Same problem. Less wasted motion.


The Head Chef Effect

Think of a senior contractor like a head chef.

You don’t pay them more because they cook longer.
You pay them because:

  • they know what not to cook
  • they catch mistakes early
  • they keep the kitchen running smoothly

A junior follows the recipe.

A senior knows when the recipe is wrong.


Expensive vs Costly

This is where most teams get it wrong.

A €100/hour contractor feels expensive.
But a cheaper hire can quietly become costly.

Because real cost includes:

  • delays from poor decisions
  • bugs that hit production
  • time spent rewriting weak foundations
  • team members getting blocked

One bad technical decision can erase months of “savings.”

Senior contractors charge more because they reduce those risks upfront.


You’re Also Buying Independence

A senior contractor doesn’t need constant direction.

They:

  • clarify vague requirements
  • challenge unclear thinking
  • make decisions without waiting
  • keep things moving

That independence means:

  • fewer meetings
  • less management overhead
  • faster delivery

And that’s often where the real value shows up.


The Hidden Math Behind the Rate

Contractors don’t get:

  • insurances
  • paid leave
  • bonuses
  • job security
  • company benefits

They also cover things employees often don’t think about:

  • paying their own taxes
  • buying and maintaining their own devices
  • paying for certifications and continuous learning
  • handling downtime between projects

Their rate isn’t just about today—it’s spread across uncertainty, investment, and risk.

In many cases, after all of that, the money a contractor actually takes home isn’t wildly different from a full-time employee.

It just looks higher on paper.


A Better Question to Ask

Instead of asking:

“Why are they so expensive?”

Ask:

“What happens if we don’t hire someone at this level?”

Because delays, rework, and poor decisions usually cost far more than the rate itself.


In the end, €70-€120 per hour isn’t premium pricing.

It’s the price of fewer mistakes, clearer thinking, and faster results.
