Transparently Calculate Software Development Costs

Software project costs are hard to estimate. Many factors play a role: complexity, scope, technology, and integrations. Our interactive cost calculators give you a first realistic estimate – no hidden costs, no surprises, and no obligation.

As a software agency from Germany with over 25 years of experience, we know how important cost transparency is. Many companies hesitate to take the first step because they cannot assess the financial impact. Our calculators provide clarity. They are based on real projects and current market prices.

What Factors Influence Software Costs?

Every project is unique. The main cost drivers are:

  • Scope and complexity: A simple landing page costs less than a full ERP system. More features and business logic mean higher effort.
  • Design: Standard templates cost less than custom UI/UX. For a strong brand, custom design is often worth it.
  • Technology: Your choice of language, framework and infrastructure affects both build and running costs.
  • Integrations: Links to ERP, CRM, payment or APIs add effort but are often essential.
  • Quality: Higher security, performance and test coverage mean more effort but pay off long term.

Why Are Our Cost Calculators Accurate?

Our calculators are based on over two decades of project experience. We have delivered hundreds of projects – from simple websites to complex enterprise apps. That experience feeds directly into our models. The typical difference between calculator result and final quote is about 20–30%. It depends on how detailed your requirements are when we talk.

Who Are the Cost Calculators For?

They are for decision-makers in mid-sized companies, startups and enterprises who need a first budget idea. Whether you want to develop a mobile app, plan a web application, integrate AI or modernise legacy systems, our calculators give you a clear starting point.

One-Time vs. Ongoing Costs

When you budget, separate one-time development costs from ongoing costs. One-time covers conception, design, development, testing and go-live. After launch you have hosting, domain, SSL, maintenance and updates, and possibly licences. Our calculators include both so you can estimate total cost of ownership (TCO).

Next Step: From Calculator to Quote

After using a calculator you get an initial price range. For a binding quote we offer a free initial consultation. We discuss your requirements, answer questions and find the best solution. The consultation is free and without obligation.
