“Staff augmentation is cheaper than hiring.” You hear it in every pitch deck. Sometimes it is true. Often it is not. And the reason has less to do with recruiting fees or benefits than most people think.

So I did the arithmetic with public numbers only: what a full-time developer really costs an employer in the US and in Germany, per hour they actually work. From that you can compute a single number that settles the question for your own case: the break-even rate, the highest hourly rate an outside specialist can cost before hiring becomes the cheaper option.

There are no market rates in this article and no provider names. Agency rates vary too much, and I found no published rate survey with a clear method. Instead you get a calculation you can repeat with the quotes on your own desk. Nothing here is legal or tax advice.

Key takeaways

• A salary is not the cost. In US private industry, employers pay about 28 to 29 cents in benefits on top of every dollar of salary, according to the Bureau of Labor Statistics (June 2026). In Germany, Destatis puts non-wage labour costs at 29 euros on every 100 euros of gross pay (2025).
• A median US software developer costs about $95 per hour actually worked. That is my calculation from the BLS median wage ($135,980, May 2025) and the BLS employer cost data. In Germany, an hour worked in the information and communication sector cost employers €58.50 on average in 2025.
• Recruiting fees barely move the result. SHRM’s 2025 benchmark puts the average cost per hire at $5,475 for non-executive roles. Spread over one year of work, that adds about $3 per hour.
• Utilisation decides it. If you only have real work for half of a new hire’s hours, every useful hour costs twice as much. At 50 percent, the break-even rate climbs from about $98 to about $197 an hour.
• Augmentation tends to win for short, uncertain or specialist work. Hiring tends to win for long-running core work that keeps a person busy, and for knowledge you cannot afford to lose.
• AI shifts the inputs, not the logic. The evidence on how much faster coding agents make developers is still unsettled. What AI clearly adds is a new kind of short, specialist project, and a new reason to keep knowledge in-house.

What a full-time hire really costs

Start with the United States. The Bureau of Labor Statistics measures what employers pay per hour worked in its Employer Costs for Employee Compensation survey. For June 2026, private industry employers paid an average of $46.89 per hour worked: $32.82 in wages and $14.07 in benefits.

For the occupational group that includes software developers, “management, professional, and related”, the numbers are higher: $78.88 per hour worked, of which $54.06 is wages. Paid leave adds $7.37, insurance $5.87, legally required benefits such as Social Security and unemployment insurance $5.07, supplemental pay such as bonuses $3.59, and retirement $2.92.

Two things follow from those figures.

• The load factor. A salary pays for hours worked and for paid leave. Everything else is on top. For this group, that “everything else” adds about 28 percent (+28%): $78.88 divided by $61.43 (wages plus paid leave) is 1.28.
• The hours. Paid leave is about 12% of salary-type pay in the same data; the other 88% pays for hours actually worked. So of 2,080 paid hours a year (52 weeks × 40 hours = 2080), a typical professional actually works about 1,830.

Now take a software developer at the US median wage, which the BLS put at $135,980 in May 2025 (about $136K). Multiply by 1.28 and the employer’s annual cost is about $174,600 (roughly $175K). Divide by 1,830 hours actually worked ($175K ÷ 1,830): about $95 per hour.

Germany measures it slightly differently, but the result is strikingly similar. Destatis reports that employers paid €29 in non-wage labour costs for every €100 of gross earnings in 2025. That is +29% on top of gross pay, next to +28% in the US example. An hour of work cost employers €45.00 on average across industry and services, about 29 percent more than the EU average of €34.90. In the information and communication sector, it was €58.50 per hour worked, up from €49.00 in 2020. That figure already includes holiday pay and the employer’s social contributions, so it is directly comparable with the $95.

Careful with the comparison: the German figure is a sector average across all jobs in IT and telecoms, not just developers. The US figure is for one occupation at its median. Use each as a starting point, not as a salary benchmark.

The worked calculation

Here is the core of it. Every input is either a published figure or an assumption I mark as one.

Step 1: cost per hour actually worked. About $95 for a median US developer (published BLS figures, my calculation). Germany, information and communication sector: €58.50 (Destatis).

Step 2: add the cost of hiring. SHRM’s 2025 benchmarking survey, with 2,371 member organisations, puts the average cost per hire for non-executive roles at $5,475. That covers agency and advertising fees, job boards, referral bonuses, travel, relocation and recruiter pay. The median is much lower, $1,200, because a few expensive hires pull the average up. These are all roles, not only tech roles. Using the higher average, and assuming the person stays one year, the hiring cost adds ≈ $3/hour (+$3 per hour worked), and the cost rises to about $98 per hour worked. Over three years it is about $96.

Step 3: ask how much of that time you really need. This is the assumption that matters most, and only you can fill it in. I call it utilisation: the share of a new hire’s working hours for which you have valuable work that needs their skills.

Step 4: divide. The break-even rate is the cost per hour worked divided by utilisation.

Read it like this. If you have a full year of work for a developer, an outside specialist is only cheaper on the invoice if the all-in hourly rate stays below about $98. If you only have 6 months of real work but a new hire would stay on the payroll for 12 months, every useful hour costs twice as much (×2), and the break-even rate is about $197: at any all-in rate < $197 per hour, augmentation is the cheaper option.

What the table leaves out, on purpose:

• Costs that hit both sides, such as onboarding, laptops, software licences and the manager’s time. If you expect them to differ, add them where they belong.
• The 44 days. SHRM’s median time to fill a non-executive role in 2025 was 44 calendar days, from opening the requisition to the accepted offer; at the largest organisations it was 61. Work that waits has a cost the table cannot see. If a project cannot wait six weeks, that may matter more than the hourly rate.
• Notice periods and severance. Ending employment has its own rules and costs, especially in Germany. They make a short-term hire even more expensive.

When staff augmentation is the cheaper choice

The calculation points to four situations:

1. Short projects. A migration, a security review, a launch. When the work ends, a hire’s cost does not.
2. Uncertain demand. If you do not know whether the product will need two engineers or six next year, flexible capacity protects you against hiring for a peak that never comes.
3. Rare skills for a limited time. A specialist you need for three months, such as for an AI integration, a database migration or a compliance project, would sit underused afterwards.
4. Speed. If the work has to start now and a hire takes a month and a half to land, the delay has a price of its own.

When it is not

The same arithmetic also shows where the pitch breaks down:

• Long-running core work at full utilisation. Then the break-even rate is about $96 to $98 an hour in the US example. An agency’s rate has to cover its own worker’s pay and benefits, its sales costs, the weeks its people sit between projects, and its margin. That makes it hard for an all-in rate to stay below the cost of your own employee.
• Knowledge drain. Every time an external person leaves, what they learned about your systems can leave with them. Documentation and handover cost time that never shows up on a rate card.
• Management effort. External people still need direction, code review and context. Your senior staff’s time is the hidden currency here.
• Quality and continuity. Rotating people on long-lived systems tends to produce code that nobody feels responsible for. That is a cost that arrives later.

Many teams end up with a mix: a permanent core that owns the systems and the knowledge, plus flexible capacity for peaks and specialist projects. The calculation helps decide where that line should run.

How AI changes the equation

AI changes the inputs of the calculation, not its logic. Three effects are worth separating.

Smaller core teams, maybe. If coding agents make each developer much faster, the same work needs fewer people, and the question of who to add shrinks. But the measured evidence is still thin. In a randomised controlled trial published in July 2025, the research group METR found that 16 experienced open-source developers took 19% longer on 246 real tasks when they were allowed to use AI tools of early 2025, even though they believed they had been 20 percent faster. In February 2026, METR reported that its follow-up study with 57 developers and more than 800 tasks could not produce a reliable number: 30 to 50 percent of developers said they skipped tasks they did not want to do without AI. METR now thinks developers are “likely” more sped up than in early 2025, but calls its data “only very weak evidence” for the size. Anyone who promises you exact savings from coding agents is ahead of the data.

New specialist work. Connecting AI models to company data, building agent workflows, setting up evaluation and guardrails: much of this is project work with a clear start and end. That is exactly the profile where augmentation tends to win.

More reason to keep knowledge inside. When an outside expert builds your AI workflows and leaves, the know-how about prompts, data access and failure modes leaves too. The more central AI becomes to how your company works, the more that part looks like core work. I wrote earlier about where AI coding pays off and where the money burns; the same measurement discipline applies here.

The legal line: talk to an expert

Staff augmentation sits close to two legal questions that this article cannot answer for you.

• In Germany, lending workers to another company falls under the Temporary Agency Work Act (Arbeitnehmerüberlassungsgesetz, AÜG). Among other things, § 1 (1b) generally limits the deployment of the same temporary worker at the same client to 18 consecutive months. Separately, freelancers who work like employees raise the question of bogus self-employment (Scheinselbstständigkeit); the Deutsche Rentenversicherung offers a formal status check.
• In the US, the IRS and the Department of Labor each apply their own tests to decide whether a worker is an employee or an independent contractor, and misclassification can be costly.

Which rules apply to your arrangement depends on the contract and on how the work is actually done. Ask an employment lawyer or a tax adviser before you sign. This article is not legal or tax advice.

What this means for businesses

• Calculate your own break-even rate before you talk to providers. Your salary level, your benefits and an honest utilisation estimate are all you need. Then compare the quotes you get against that number, not against a gut feeling.
• Be honest about utilisation. Most bad decisions in this area come from assuming a new hire will be fully busy, or that an external person needs no management.
• Decide what is core. Systems you will run for years, and the knowledge about them, are usually worth owning. Peaks and specialist projects are usually worth renting.
• Plan the handover from day one. If you bring in outside specialists, make documentation and knowledge transfer part of the work, not an afterthought.

What this means for tech workers

• The full cost of your job is higher than your salary. That is why an hourly rate as a contractor needs to be well above “salary divided by hours” to come out even.
• Specialist, project-shaped skills are where flexible work pays. AI integration is one such skill today.
• Permanent roles keep their value where knowledge matters. The people who understand how a company’s systems really work are the hardest to rent.

The limits of this calculation

• It is a model, not a quote. The US example uses one occupation at its median wage; the German figure is a sector average. Your numbers will differ.
• The load factor is an average. Benefits vary a lot between employers, and the BLS figure covers a broad occupational group, not developers alone.
• SHRM’s figures cover all non-executive roles in its member survey (unweighted). Tech hires may cost more or less.
• Utilisation is the big assumption, and it is yours to make.
• No agency rates. I found no published rate survey with a clear method, so I did not use any.
• AI productivity is not settled. The METR results are the best controlled evidence I found, and even METR says its newest data is weak.
