In-house AI team vs outsourced AI team: what does each really cost?
By Tarannum Khan|Updated
Short answer
On our arithmetic from public data, a median US software developer costs about $194,000 a year with benefits, and a UK employee at the machine learning median about £86,800 with employer costs. A US staffing-agency AI engineer bills $22,400 to $38,400 a month. An offshore senior developer in Asia costs $4,960 to $6,560 a month. In-house pays off when AI work is continuous and central to your product.
Key takeaways
- A median US software developer costs about $194,000 a year once benefits are added, before any recruiting fee.
- A UK employee at the £75,000 machine learning median costs about £86,800 with employer National Insurance and pension.
- Contractors and US staffing agencies cost the most per month. Offshore teams cost the least but need your management time.
- Hiring takes time too: the median technical hire took 40 days from application in published hiring data.
- Many companies keep a small in-house core and add outsourced engineers around it.

| Option | Per month | Per year | Source |
|---|---|---|---|
| US employee: median software developer, with benefits | about $16,200 | about $194,000 | BLS pay, BLS benefits |
| UK employee: machine learning median, with employer NI and pension | about £7,230 | about £86,800 | UK job-market data, GOV.UK |
| UK contractor: AI engineer median day rate, 20 days a month | £12,000 | £144,000 | UK job-market data |
| US staffing agency: AI / ML engineer, 160 hours a month | $22,400 to $38,400 | $268,800 to $460,800 | US staffing rates |
| Offshore: senior developer in Asia, 160 hours a month | $4,960 to $6,560 | $59,520 to $78,720 | 2026 rate survey |

Not like for like. BLS has no AI engineer category, so the US employee figure is the median for all software developers, and AI specialists may cost more. Agency rates include the agency's margin. Employees take paid holidays, while contractors and agencies bill only the days worked.
How we worked out the employee figures. US: the BLS median for software developers is $135,980 (BLS). Wages make up 70% of private-sector employer compensation costs and benefits the other 30% (BLS), which gives about $194,000. UK: the median for permanent machine learning jobs is £75,000 (UK job-market data). Employer National Insurance at 15% above £5,000 adds £10,500 (GOV.UK), and the minimum 3% pension contribution adds about £1,320 (GOV.UK).
When does an in-house AI team make sense?
Hire in-house when AI is the core of your product, the work runs for years, and you can wait two to three months to fill each role. Outsource when you need to start quickly, the workload varies, or you need skills for one project rather than for good.
| Situation | Better fit |
|---|---|
| AI is your core product and your main competitive edge | In-house |
| Steady AI work for years, with time to recruit | In-house |
| You need to start within weeks | Outsourced |
| The workload rises and falls, or it is one project | Outsourced |
| You need a skill you don't have, such as RAG or agent design | Outsourced, or a hybrid |
| You want to keep the know-how but grow faster | Hybrid: an in-house lead with outsourced engineers |
The hybrid model is common. An in-house lead owns the product and the architecture, and outsourced engineers add capacity. If you choose it, make sure the code, prompts and documents live in your own systems from day one, so nothing depends on the vendor.
How do you compare quotes fairly?
Compare the total monthly cost for the same scope, including your own management time and any shift premium. Then compare the terms: named engineers, shared hours, trial period, replacement and IP ownership.
- 1
Write one scope
Give every option the same description of the work, so the quotes are comparable.
- 2
Add every cost
Rate times hours, plus shift premiums, recruiting fees, employer costs and your own management time.
- 3
Check the terms
Named engineers, written shared hours, a trial on real work, replacement terms, and IP assigned to you.
- 4
Test before you commit
Run a short paid trial with an outsourced team, or a probation period with an employee, on real work.
Where does Webify.AI fit?
Webify.AI is an outsourced option, so we have an interest in this comparison. Our AI / LLM engineers cost $6,100 a month on a 160-hour plan, or $45 an hour. We suit companies that want to add AI engineers quickly, or run a hybrid team with their own lead.
- We send two named engineer profiles within 48 hours, and you choose who to interview.
- Two-week trial with the developer you choose. No charge if you stop within the first five working days.
- Hourly plans start at 80 hours a month, so you can begin with one engineer part time.
- We sign your NDA before the first call, the IP in all code is assigned to you, and the work goes into your repositories.
- We are not the right choice if you need people in your office, or a vendor with ISO 27001 or SOC 2. We hold neither.
Frequently asked questions
Is it cheaper to outsource AI development than to hire in-house?
Per month, usually yes, especially offshore. An in-house team can cost less over several years if the work is steady and people stay. Count recruiting, employer costs and your own management time on both sides.
How much does an AI engineer cost per year in the US?
BLS has no AI engineer category. The median software developer earned $135,980, which comes to about $194,000 a year with benefits on BLS's 70/30 split of wages and benefits. AI specialists may cost more.
How much does an AI engineer cost per year in the UK?
The median for permanent machine learning jobs is £75,000. With employer National Insurance and the minimum pension contribution, that is about £86,800. AI engineer contractors charge a median £600 a day.
How long does it take to hire an AI engineer?
Expect several weeks for a permanent hire. In published hiring data, the median technical hire took 40 days from application and 76 days from opening the job, before any notice period. Outsourced teams can usually start sooner.
Can we start with one outsourced engineer part time?
With us, yes. Hourly plans start at 80 hours a month. Other vendors set their own minimums, so ask before you compare prices.
