Cost Calculators for Software Projects
In brief
What range the cost calculators show before a quote
Cost calculators for software projects show a first range before you invest, covering app development, web work, AI integration, and legacy modernization. Use is free and without obligation, with no registration. The figure depends on scope, complexity, and quality requirements. It draws on more than 250 delivered projects and current market prices.
- A dedicated calculator per project type
- A range, not a fixed-price quote
- A result within a few minutes
- Scope agreed before a proposal
- Grants checked in a separate calculator
- Inputs stay on this page
A fixed quote follows once the scope is clear. Book a consultation or open cost calculators by category.
Ranges use Groenewold IT Solutions project data; industry framing: Bitkom (2025).
Next steps before you calculate
Choose your project type, answer a few questions, and get a range. For context before you dial in numbers, see our topics overview and technology comparisons. For complex projects, start with our discovery workshop cost calculator. Besides cost, timing matters: see our realistic project durations for app, ERP, custom software and AI projects with phases and influencing factors. Project budgets and billing models are explained transparently on the pricing page. Prepare your scope with the requirements specification generator, or use the digital maturity check to prioritize the next step.
For existing systems, use the legacy risk assessment and the software audit checklist. Assess integration projects with the integration readiness check, then generate a phased plan with the migration roadmap generator.
Define new initiatives with the API requirements generator and the software budget finder. The make-or-buy decision assistant evaluates sourcing options, while the cloud readiness check assesses the technical starting point.

Indexable sample calculations
Realistic static scenarios with assumptions and budget ranges for internal planning and stakeholder alignment.
Typical project scenarios with budget ranges
Each scenario documents assumptions, scope and an indicative budget band — useful for comparing your own project against a realistic mid-market baseline before you open a calculator.
- What does a customer portal with ERP and SSO cost? (EUR 49,000 – 101,500, assumptions documented)
- What does a cross-platform app with offline sync cost? (EUR 32,200 – 73,500, assumptions documented)
- What does on-prem to Azure with cutover cost? (EUR 54,600 – 127,400, assumptions documented)
- What does a pentest including retest cost? (EUR 11,200 – 30,100, assumptions documented)
- What does Odoo with 6 modules and migration cost? (EUR 38,500 – 82,600, assumptions documented)

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 German software agency founded in 2010, 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 use approved planning assumptions from our project and pricing models.
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?
Each category hub keeps its own calculator, so an app range is not reused for ERP or legacy work. How close that range sits to a later quote depends on how clearly the scope is described in the call.

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, review AI chatbot costs and pricing factors, 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).

FAQ
Software Cost Calculators
Accuracy & Next Steps
How accurate are the cost calculators?
They give a first orientation based on typical project sizes.
For a precise quote we need a short briefing; we then provide a transparent estimate.
What is included in the estimates?
Development, testing, project management and documentation.
Hosting, licences and ongoing support are quoted separately if required.
Can we get funding for our project?
Often yes.
We have a funding calculator and can advise on grants for digitalisation and R&D; we support applications where it makes sense.
Do you offer fixed-price projects?
Yes, for well-defined scope.
For evolving requirements we work in phases with transparent pricing per phase.

Software costs: calculators and consulting
Which cost calculator to open first
Four checks: the project, one short answer, no second figure, and the next step. The euro bands stay on the calculator pages.
1. Match the project
Software, integration, AI, operations or funding. Each area has its own calculators.
2. Read the short answer
The lead band appears once on the calculator page. The overview does not repeat it.
3. Do not mix bands
A shop frame and an ERP frame are different projects. They are not added.
4. A call instead of an average
If two calculators fit, the intro call sets the scope. An average of both is not an estimate.
