Web Development Costs: Transparent Estimates for Websites and Web Apps

Use our interactive calculator for an initial cost estimate. Whether website, online shop or SaaS – transparent and without obligation.

In brief

One investment frame for web development

The investment frame for web development is EUR 14,875 – 164,063 excl. VAT. Web app, portal and SaaS scope change the extent, not four separate prices.

The upfront cost can be spread over 72 months. Terms are on the software financing page.

How the web-development cost range is built

The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.

  1. 1. Capture inputs

    The calculator records the visible project, volume, complexity and operating parameters selected on this page.

  2. 2. Add fixed components

    Fixed base modules and selected add-ons are added without mixing them with recurring charges.

  3. 3. Apply multipliers

    Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.

  4. 4. Create the range

    The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.

  5. 5. Round and calibrate

    Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.

  6. 6. Classify the result

    The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.

Included

  • Inputs shown in the calculator
  • Calculator-specific base values and factors
  • Displayed one-off and recurring result components

Not included

  • Requirements not selected in the calculator
  • Unknown data migration and third-party licence costs
  • Taxes, legal advice and a binding delivery commitment

Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.

Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.

In-House Development vs. Agency

When does an in-house team make sense, when an agency? An honest comparison:

✓ Agency makes sense for:

  • • Project-based needs (no permanent team required)
  • • Specialized know-how needed (AI, legacy, integrations)
  • • Quick start without recruiting effort
  • • Scalability during project fluctuations

✓ In-house team makes sense for:

  • • Permanent, full-time development needs
  • • Core IP that should stay in-house
  • • Long-term product development
  • • Budget for recruiting, onboarding, management

Frequently asked questions

Web Development Costs

Costs & project types

How much does a web application cost?

Web applications sit in the investment frame EUR 14,875 – 164,063 excl.

VAT. Complexity, design, features and integrations place the project inside that range.

How much does an online shop cost?

E-commerce sits in the same investment frame.

Product count, payment providers and integrations change the scope, not a second list price.

How much does SaaS development cost?

A SaaS scope with tenants and subscriptions stays in the same investment frame.

A focused MVP is the lean end of that range.

How much does a portal or platform cost?

Portals and platforms stay in the same investment frame.

User roles, features and integrations change the position inside it.

Design & scope

Template or custom design?

A template stays at the lean end of the investment frame and is faster to ship.

Custom design uses the upper part of the same range when brand or UX requires it.

How long does web development take?

Web app: 2-4 months.

Portal: 3-6 months. SaaS: 4-12 months.

What is included in the price?

Conception, design, development, testing, basic SEO, deployment.

Optional: hosting, maintenance.

Technology & collaboration

What are the ongoing costs?

Hosting, domain and updates are quoted apart from the project investment frame.

Ongoing care follows the monthly range on the software maintenance calculator.

Which technology is the right one?

React/Next.js for modern web apps, Vue.js for rapid development, Angular for enterprise.

The choice depends on team expertise, scaling requirements and existing infrastructure.

Can we start with an MVP?

Yes, recommended!

An MVP focuses on core features, validates the idea in the market and costs 30-50% less than a full version. Expand iteratively after feedback.

Timeline & ongoing costs

How does the collaboration work?

Agile development in 2-week sprints with regular demos.

You continuously see results, can prioritize and give feedback. Transparent communication via Slack/Teams.

Do I need a custom design?

Not necessarily.

With Tailwind CSS and modern component libraries, we create professional UIs without a separate design budget. Custom design is worthwhile for strong brand identity.

More about web development

Web development: cost estimate

Which inputs move web development

Four checks: content or application, editing, integrations and operations. No second price next to the short answer.

  1. 1. Content or application

    An editorial website and an application with its own transactions are not the same effort.

  2. 2. Fix who edits

    Who maintains copy and media chooses the system. A page builder is a different path from a custom screen.

  3. 3. Count integrations

    Shop, CRM, login and payment each count. Every connection moves the scope.

  4. 4. Plan operations

    Hosting, updates and who maintains the site after launch belong in the estimate.

Typical pricing models (overview)

Comparison: typical pricing models for software and IT projects
ModelWhen it fitsBudget & flexibilityTypical risks
Fixed price (fixed scope)Clearly defined scope, stable requirements, repeatable delivery.Predictable total cost; little room for change without a change order.Scope creep leads to change orders or quality trade-offs.
Time & MaterialDiscovery, legacy, evolving requirements, or close collaboration.Maximum flexibility; budget transparent via hourly or daily rates.Without prioritisation, effort can grow—backlog and reviews matter.
Retainer / maintenance packageOngoing operations, updates, small features, and support.Agreed capacity per month; predictable follow-on cost.Large changes may still need a separate estimate.
Hybrid (milestone + T&M)MVP or phased releases with clear go-lives, then iterate.Core delivery fixed price; extensions on a time-and-materials basis.Define contractually what is in scope vs. extra work.

Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.

What determines the costs, and what comes next?

The ranges shown are indicative. For a binding quote we discuss scope, priorities and funding options in a free intro call. Many digitalization projects qualify for grants – try our funding calculator.

The calculator result for web development is indicative only – a binding budget follows scope alignment, data review, and quality targets.

Plan follow-on costs

  • Operations and maintenance separate from the initial build
  • Internal key users and training
  • Monitoring and support after go-live
