.NET is the platform of choice for many Polish banks, insurers, manufacturers and companies built around the Microsoft ecosystem. Demand comes both from new cloud applications on Azure and from the long tail of older systems that need to be maintained and modernised. This page sets out what a .NET developer costs in 2026 — as a provider rate and as the developer’s own earnings. All provider rates come from our body leasing rate benchmark for 2026 and are net of VAT.
How much does a .NET developer cost in Poland in 2026?
The table shows what a client pays for a .NET developer through staff augmentation, by seniority. Daily rates assume an eight-hour day; monthly figures assume 160 billable hours. Euro values use 4.30 PLN per EUR.
| Seniority | PLN per hour | PLN per day | EUR per day | PLN per month (160 h) |
|---|---|---|---|---|
| Junior | 90-130 | 720-1,040 | 165-240 | 14,400-20,800 |
| Mid | 130-180 | 1,040-1,440 | 240-335 | 20,800-28,800 |
| Senior | 180-260 | 1,440-2,080 | 335-485 | 28,800-41,600 |
| Lead / principal | 260-350 | 2,080-2,800 | 485-650 | 41,600-56,000 |
.NET sits in the same benchmark band as Java and Python backend development. Where a developer lands within the band depends on the factors described below. On-site work in a large city usually adds 10-15%, and very short engagements of under three months add 15-25%.
How much do .NET developers earn in Poland?
The provider rate and the developer’s pay are two different numbers. The most detailed public source for pay by language is the Bulldogjob IT Community Survey 2025. On employment contracts it reports take-home (net) pay; on B2B, the net amount on the invoice.
- Developers whose main language is C# (all seniority levels): median PLN 21,680 on B2B and PLN 9,000 take-home on employment.
- Senior backend developers (all backend languages): median PLN 25,000 on B2B and PLN 14,000 take-home on employment.
- Mid-level backend developers: median PLN 17,000 on B2B and PLN 9,416 take-home on employment.
The gap between B2B and employment is wide for C#: the B2B median is more than twice the take-home employment median. Part of the explanation is that take-home pay is after tax and social security, while the B2B figure is before them. A take-home salary of PLN 9,000 corresponds to roughly PLN 13,000 gross a month under 2026 tax rules. We explain the conversion in our comparison of B2B and employment net pay.
These are survey medians, not offers. Senior .NET developers with Azure architecture or financial systems experience earn well above them.
Why is the provider rate higher than the developer’s own rate?
A senior .NET developer invoicing PLN 150-170 an hour directly and the same developer placed through a provider at PLN 180-260 an hour are not the same purchase. The provider rate includes:
- Recruitment and vetting — sourcing, technical interviews and reference checks.
- A replacement guarantee — if the developer leaves or does not fit, the provider supplies a replacement.
- Administration — the contract with the specialist, invoicing and compliance.
- The provider’s margin.
The client also pays only for hours worked, with no pay for holidays, sick leave or gaps between projects. We compare this with direct employment and direct B2B in our analysis of total employer cost in Poland in 2026. In that model, a directly hired senior costs about PLN 219 per productive hour.
What pushes a .NET developer’s rate up?
Within each seniority band, the price depends mostly on the ecosystem and the domain:
- Current .NET versions. .NET 10 was released on 11 November 2025 as a long-term support release, supported until November 2028. Senior developers are expected to know modern ASP.NET Core, Entity Framework Core and current C# features.
- Legacy modernisation. Many companies still run applications on the old .NET Framework. Developers who can migrate them to modern .NET without stopping the business are in demand.
- Azure. Production experience with Azure services — App Service, Functions, Service Bus, Azure SQL — is often the deciding factor. Microsoft certifications such as Azure Developer Associate help show it.
- Enterprise domains. Banking, insurance and manufacturing systems bring requirements such as integration with ERP systems, security and audit. Developers who have worked in them are harder to find.
- Leadership. A tech lead or solution architect who can shape the architecture of a .NET platform is priced in the lead band, PLN 260-350 an hour.
How do Polish .NET rates compare with Germany and the UK?
The average hourly rate of an IT freelancer in Germany is EUR 95 (freelancermap Freelancer-Kompass 2025), about EUR 760 for an eight-hour day. A senior .NET developer from Poland through staff augmentation costs EUR 335-485 a day, so the Polish rate is typically 35-55% lower — and the German figure is a direct freelancer rate, without any agency margin.
In the UK, the median contract rate for a senior developer was GBP 525 a day in the six months to 16 January 2026 (IT Jobs Watch), about EUR 610. Against that, the Polish senior rate is roughly 20-45% lower.
What monthly budget should you plan for a .NET team?
A typical team modernising a .NET application — one lead, one senior and two mid-level developers — at the middle of each band costs about:
- Lead: PLN 305 per hour × 160 h = PLN 48,800
- Senior: PLN 220 × 160 h = PLN 35,200
- Two mid-level developers: 2 × PLN 155 × 160 h = PLN 49,600
That is about PLN 133,600 a month, or roughly EUR 31,100. In a modernisation project, the lead’s experience with the old and new platform matters more than the size of the team, because most of the risk lies in migration decisions.
What should a request include to get an accurate .NET quote?
A precise request narrows the rate band and shortens the time to start. Before asking providers for a .NET developer, it is worth writing down:
- The actual scope of work — new development, maintenance or migration, and the parts of the system the developer will own.
- The stack in detail — .NET version, ASP.NET Core or legacy .NET Framework, Entity Framework and Azure services, plus the cloud and CI/CD tools the team uses.
- Domain and constraints — a regulated industry, security requirements, and the languages the developer must work in, such as English or German.
- The working model — remote or on-site, time-zone overlap, the expected start date and the length of the engagement.
- The team around the role — team size, whether there is a tech lead and how technical decisions are made.
The last point matters more than it seems. A senior developer joining a team without a lead often has to take on part of the lead’s work, which moves the right profile — and the rate — upwards. Stating this at the start avoids a mismatch after onboarding.
When is staff augmentation better than hiring a .NET developer directly?
Hiring directly is cheaper per hour if you need the same person for several years and can find them in a reasonable time. Staff augmentation wins when the need is time-limited, urgent or hard to fill — for example, a one-off migration from .NET Framework. In our cost model, the break-even point against a direct B2B contract is about nine months. We compare the two models in B2B contract or body leasing in 2026.
How can you hire a .NET developer through ARDURA Consulting?
We provide .NET developers through staff augmentation: the specialist joins your team, works in your tools and processes, and you are invoiced for hours worked. Before proposing a rate, we check which seniority and profile the role really needs.
Current rate ranges for all roles are on our pricing page, and a broader overview is in our software development rates guide. If you are planning a .NET team, talk to our team.
