How Much Does a Senior Engineer in Romania Really Cost Compared to the UK, Germany and US?

Hiring a senior engineer in the wrong market can cost a company tens of thousands of euros more every year.

And that is before you calculate what happens when the role stays vacant for 75 days.

For a CFO, that changes the question.

It is not simply, “How much does a senior developer earn in Romania?”

The better question is:

“What will this engineer actually cost my company compared with an equivalent hire in the UK, Germany or the US?”

That calculation includes salary, employer payroll costs, benefits, infrastructure and the cost of waiting for the position to be filled.

Using BrainSource’s 2026 cost model, a senior engineer costs an estimated €69,985 per year in Romania, compared with €113,500 in the UK, €112,400 in Germany and €180,000 in the US.

That puts the modeled annual saving at €43,515 per engineer versus the UK, €42,415 versus Germany and €110,015 versus the US.

That is the nearshore business case in its simplest form.

But the interesting part is what happens when you stop looking at one hire.

Start With the Fully Loaded Cost

Salary comparisons are useful for recruitment.

They are not enough for finance.

If a company pays a senior engineer €90,000 in Germany, the company’s cost is not simply €90,000. Employer social-security contributions and other employment costs sit on top of the salary.

The same applies in the UK, where the standard employer National Insurance rate for 2026–27 is 15% above the relevant secondary threshold.

The US has its own employer payroll costs and benefits structure.

Romania has a different cost profile. BrainSource’s current 2026 model uses a 2.25% employer CAM contribution on Romanian CIM salaries and adds a standard health-and-perks allowance to arrive at total employer outlay.

That gives us a more useful comparison.

BrainSource 2026 modeled assumptions. Actual employer costs vary by employee, compensation package, location, benefits and local tax circumstances.

The difference is significant.

A Romanian senior engineer in this model costs €43,515 less per year than the UK equivalent.

Against Germany, the difference is €42,415.

Against the US, it is €110,015.

That works out to approximately 38% lower modeled employer cost than the UK, 38% lower than Germany and 61% lower than the US.

This is why a proper nearshore engineering cost comparison should start with total employer cost rather than advertised salary.

What Does That Mean for a Five-Person Team?

One engineer is useful for illustrating the difference.

A team is where the financial impact starts becoming difficult to ignore.

Take five senior engineers.

At the BrainSource modeled cost, five Romanian engineers would cost approximately €349,925 per year.

The same five-person team would cost approximately €567,500 in the UK, €562,000 in Germany and €900,000 in the US.

The Romanian team therefore represents a modeled saving of more than €200,000 a year against both the UK and Germany, and more than half a million euros against the US.

That is no longer a salary optimisation exercise.

It is a workforce strategy decision.

Ten Engineers Changes the Conversation

Now double the team.

Ten senior engineers in Romania would cost approximately €699,850 per year under the same assumptions.

The UK team would cost €1.135 million.

Germany would cost €1.124 million.

The US would cost €1.8 million.

At ten engineers, the difference between Romania and the US reaches €1.1 million per year under this model.

Against Germany, it is more than €424,000.

Against the UK, more than €435,000.

This is the point where the word nearshoring starts to mean something very different to a CFO than it does to a recruiter.

It is not just about finding a developer for less.

It is about deciding where the company’s engineering budget creates the most capacity.

But Salary Arbitrage Is Only Half the Story

There is another cost that does not appear in the salary column.

The empty seat.

BrainSource’s ROI model currently uses 75 days as the default internal DIY time-to-fill assumption and compares that with a 21-day fast-track hiring scenario.

That matters because an approved position does not create engineering output.

An engineer does.

Until someone is hired, the company is carrying the need for the role without getting the capacity the role was supposed to provide.

We can calculate the annualised cost of those 75 days.

Using 365 days in a year:

75 ÷ 365 = 20.55% of a year.

Apply that to each market’s modeled annual employer cost.

For Romania:

€69,985 × 20.55% = approximately €14,380.

For the UK:

€113,500 × 20.55% = approximately €23,322.

For Germany:

€112,400 × 20.55% = approximately €23,096.

For the US:

€180,000 × 20.55% = approximately €36,986.

There is an important distinction here.

These figures do not mean a company literally loses €14,380, €23,322 or €36,986 in salary during a vacancy. The company is not paying the unfilled employee.

They represent the portion of the annual employment budget associated with 75 days of capacity that has not yet been hired.

The actual cost of vacancy can be higher because the missing engineer may be delaying projects, increasing workload for existing staff, pushing back product releases or preventing revenue-generating work from starting.

That is where the vacancy calculator becomes more valuable than a simple salary calculator.

The Cost of Vacancy Is Not Just Payroll

Imagine a company needs a senior backend engineer to finish a critical product feature.

The hiring manager opens the position.

Recruiting starts.

Candidates are sourced.

Interviews happen.

Technical assessments are completed.

Offers are negotiated.

And 75 days later, the person finally starts.

The company may not have spent an extra €20,000 on salary during those 75 days.

But the engineering work that person was supposed to perform still has to happen.

Someone else may absorb it.

A project may move.

A launch may be delayed.

An existing engineer may spend two weeks working on something outside their planned priorities.

A manager may spend hours interviewing instead of running the team.

Those costs are much harder to see in a finance report.

They are still costs.

That is why the strongest nearshore business case combines direct arbitrage with hiring friction.

Romania vs Germany: What Does the Difference Actually Buy?

Let’s take the German comparison because it is one of the clearest examples.

The modeled annual cost is:

Germany: €112,400

Romania: €69,985

Difference:

€42,415 per senior engineer per year.

For five engineers:

€212,075.

For ten:

€424,150.

That means a company building a ten-person senior engineering team could have more than €400,000 of modeled annual cost difference between the two locations.

The important word is modeled.

The exact result for a real company will change according to salaries, benefits, location, employment structure and the seniority of the people being hired.

But the exercise shows CFOs what they should be calculating.

Not “What does a Romanian developer make?”

“What does my engineering capacity cost in each market?”

Romania vs the UK: Employer Costs Matter

The UK comparison tells a similar story.

The modeled annual cost is €113,500 in the UK versus €69,985 in Romania.

That produces a difference of:

€43,515 per senior engineer.

For ten engineers, that becomes:

€435,150 per year.

The UK’s employer National Insurance burden is one reason gross salary cannot be used as the final comparison. From April 2026, the standard employer Class 1 rate is 15% above the applicable secondary threshold.

That does not mean every UK employee generates exactly 15% additional cost. Thresholds, employee categories and other employment costs matter.

It does mean that comparing a Romanian salary directly with a UK salary without considering employer-side costs produces an incomplete calculation.

Romania vs the US: Where the Gap Gets Large

The US produces the biggest difference in this model.

The modeled annual employer cost for a senior engineer is €180,000.

Romania:

€69,985.

Difference:

€110,015 per engineer.

For ten engineers:

€1,100,150 per year.

That is a seven-figure annual difference.

Again, this is not a promise that every company will save €1.1 million by moving ten engineering roles to Romania.

It is the result of one defined set of assumptions.

Change the salary.

Change the benefits.

Change the seniority.

Change the hiring model.

The answer changes.

That is precisely why companies should model their own numbers rather than copy somebody else’s benchmark.

What Happens When You Add Infrastructure?

People often remember salary and forget everything around salary.

An engineering employee may require a laptop, software licences, security tools, workspace, equipment replacement, travel, benefits and other operating expenses.

Those costs are relatively small compared with compensation, but they still belong in the model.

BrainSource’s current comparison therefore includes a standard health-and-perks load rather than treating gross salary as the complete employer cost. The model uses €2,500 for Romania, €5,000 for the UK, €3,500 for Germany and €15,000 for the US.

That is a better way to think about the problem.

The CFO does not approve “€66,000 salary.”

The CFO approves a total employment budget.

The 75-Day Problem Becomes Bigger With Every Hire

There is another reason vacancy matters more as teams grow.

One unfilled senior engineer is one problem.

Ten unfilled positions are a capacity problem.

If a company is trying to build a ten-person engineering team and each role takes 75 days to fill, the organisation is not dealing with one vacancy.

It is managing a pipeline of missing engineering capacity.

The timing of those vacancies matters.

A team that eventually reaches ten engineers but takes months to get there does not have the same delivery capacity as a team that reaches ten engineers quickly.

This is where hiring velocity becomes part of the financial model.

The question changes from:

“How much does this engineer cost?”

to:

“How quickly can we turn this engineering budget into productive capacity?”

The CFO Calculation Should Look Like This

A useful nearshore engineering cost comparison should combine the direct and indirect numbers.

Start with the annual compensation.

Add mandatory employer costs.

Add benefits and infrastructure.

Calculate the total annual employer outlay.

Then calculate the cost associated with the vacancy period.

Finally, compare the result against the alternative market.

That gives you something much more useful than a salary table.

It gives you a business case.

Ten-Engineer Business Case

The final published version of this table should be exported directly from the SalCal ROI output, using the same assumptions shown in the article.

This Is Where SalCal Becomes More Than a Salary Calculator

A salary calculator tells you what someone earns.

A CFO needs to know what the hiring decision costs.

SalCal’s ROI model is designed around that broader question. It lets you enter the domestic salary, Romanian hiring budget, employer costs and the internal DIY time-to-fill assumption, with 75 days currently set as the default. It then separates direct arbitrage from frictional costs such as vacancy and recruitment.

That matters because your business is not BrainSource’s benchmark.

Maybe your German senior engineer costs €125,000.

Maybe your UK package is £130,000.

Maybe your US role includes significant equity.

Maybe your Romanian candidate expects €6,500.

Maybe your company takes 90 days to hire.

Those numbers produce a different answer.

And that is exactly what the calculator should do.

Final Thoughts

There is a lazy version of the nearshore argument:

“Romanian developers are cheaper.”

That is not a CFO argument.

The stronger argument is:

“For the same engineering budget, which market gives us the most productive technical capacity?”

That calculation takes salary out of isolation.

It considers employer costs.

It considers infrastructure.

It considers hiring speed.

It considers the cost of waiting.

And when you scale from one engineer to five or ten, it shows how a relatively modest difference in annual cost can become hundreds of thousands of euros.

Under BrainSource’s current 2026 model, a ten-person senior engineering team costs approximately €699,850 in Romania compared with €1.135 million in the UK, €1.124 million in Germany and €1.8 million in the US.

That is a modeled annual difference of €435,150 against the UK, €424,150 against Germany and €1.1 million against the US.
