App Cost Calculator
Mobile App Development Cost Calculator (Europe 2026)
Stop guessing. Get a realistic estimate based on verified agency rates from 14 countries—not random algorithms.
Most online calculators are lead-generation black boxes. This tool uses verified 2026 hourly rates from European agencies to show you exactly where every Euro goes.
Project Scope
Scope is the #1 cost driver. Number of screens correlates directly with design and development hours.
Each screen requires design (€200–400) and development (€600–800).
Having Figma files ready saves 18–25% (skips design phase).

Where Do These Numbers Come From?
Based on Verified 2026 Rate Cards
No random algorithms. These estimates are based on real rate cards tracked across Western Europe (Avg: €85–€130/hr) and Eastern Europe (Avg: €45–€75/hr).
The "Hidden" Costs Are Included
Most founders forget that building the app is only 60% of the cost. Our calculator includes the critical phases others skip: Discovery & Research (15%), Project Management (15%), and QA & Testing (10%).
These figures are estimates only. Actual costs depend on your specific requirements, agency selection, and project complexity. For a detailed breakdown of cost factors, read our full mobile app pricing guide →
Western vs. Eastern Europe: The Quality Myth
You'll notice a €30,000+ difference between hiring in the UK/Germany versus Poland/Romania. Does cheaper mean worse quality? Generally, no.
The price gap is economic, not technical. You are paying for London's cost of living, not better code. Senior talent in Warsaw delivers the same quality for 50% less.
Hire locally (UK/DE/NL) if:
You need onsite collaboration, legally complex contracts, or culturally specific design nuances.
Hire nearshore (PL/RO/UA) if:
You want the same code quality for 40% less and are comfortable working in English over Zoom.
Frequently Asked Questions
How much does it cost to build a mobile app in Europe?
A simple app (10-15 screens) costs €25,000-€60,000 in Western Europe or €15,000-€35,000 in Eastern Europe. Complex apps (25-50+ screens) range from €80,000-€180,000 in Western Europe or €45,000-€100,000 in Eastern Europe.
Why is app development cheaper in Poland than the UK?
The price difference is purely economic (cost of living, office space, salaries)—not quality. Senior developers in Warsaw and London have identical technical skills. A 500-hour project costs ~€56,000 in London vs ~€27,500 in Warsaw, saving 51%.
What factors affect mobile app development cost?
The main cost factors are: number of screens/features, platform choice (iOS, Android, or cross-platform), backend complexity, third-party integrations (payments, maps, analytics), industry regulations, and agency location.
How long does it take to build a mobile app?
A simple app takes 2-4 months, a medium-complexity app takes 4-6 months, and complex enterprise apps take 6-12+ months. Timeline depends on scope, team size, and feedback speed.
Should I hire a local agency or outsource to Eastern Europe?
Hire locally if you need in-person workshops or culturally-specific design. Hire nearshore (Poland, Czech Republic, Portugal) if you want 40-50% savings and are comfortable working remotely.
