What does building a website cost in 2025? The honest overview

The question "what does building a website cost?" produces an alarmingly wide range of answers on Google. One provider charges €500, another €50,000 — and both claim to deliver the best work. That makes budgeting for a website difficult, especially if you don't deal with digital projects on a daily basis.

The reality is more nuanced than most overviews show. The price of a website depends on what it needs to do, for whom, and how long it needs to last. Below we set out the three main categories — with honest price ranges, an explanation of what is in that price, and an answer to the question that actually matters: when is more expensive worth it?

The three price categories

Category 1: Brochure site (€2,000 – €8,000)

A brochure site is exactly what the name says: a digital business card. Five to ten pages, a contact form, perhaps a blog. No user accounts, no complex logic, no connections with external systems.

In this segment you as a client supply the content yourself, the agency works with an existing theme or template system (WordPress, Webflow, Squarespace), and customisation is limited to visual adjustments and copy work.

What you get for this budget:

  • Responsive design (works on mobile and desktop)
  • Basic search engine optimisation
  • Contact form and optionally a newsletter integration
  • Standard CMS so you can adjust content yourself
  • Delivery within four to eight weeks

Where it falls short: A template always has limitations. If your brand is strongly visual, or if your website needs a specific user flow, you will run into the constraints of the theme. The cheaper quotes in this segment also rarely include ongoing development, hosting management, or SEO services. Budget for those as separate costs.

Category 2: Custom business website (€8,000 – €25,000)

This is the segment for companies where the website is a serious commercial instrument. No more template, but a design aligned with the brand identity, a structure built from user goals, and a technical foundation that can grow.

In this range the agency spends time on a discovery phase: what does the visitor want to achieve, which path leads them to conversion, what content is needed for that? This is followed by wireframes, design, development, and a test and review round before going live.

What this segment adds:

  • Custom UX design, tailored to your target audience
  • Performance optimisation (load time, Core Web Vitals)
  • More advanced SEO structure (schema markup, technical audit)
  • Integrations with tools like HubSpot, Salesforce, Mailchimp or a custom CRM
  • Multiple revision rounds and an acceptance test before going live

For a growing SME, a B2B service provider, or a scale-up that wants to be found seriously, this is the segment with the most value per euro.

Category 3: Custom web application (€25,000 – €80,000+)

Here you leave the territory of "website" and enter that of "software". A custom web application has its own logic: users can log in, data is stored and processed, there are connections with other systems, and there is a backend that the world doesn't see but that drives everything.

Examples: a client portal where clients view their files, a configurator where users assemble products and immediately receive a quote, or an internal tool that automates manual processes.

In this segment, the distinction between "having a website built" and "having software built" has largely disappeared. The budget goes towards architecture design, backend development, API integrations, security audits, and extensive testing.

What is actually in that price?

A common mistake is comparing quotes based only on the final amount. Two quotes of €15,000 can differ radically in what they include.

Discovery and strategy — Good agencies never start building straight away. They spend two to four weeks understanding your target audience, your competitive position, and your conversion goals. This costs time, and therefore money — but without this, a website is built on assumptions.

UX and design — The difference between a usable website and a beautiful website that doesn't convert lies in UX research. How does a new visitor navigate? Where do people drop off? A good UX phase costs €2,000–€8,000 depending on complexity, and almost always delivers more than it costs.

Development and technology — Here is where the largest part of the budget sits. Including frontend (what you see), backend (what processes data), hosting setup, and security settings.

Content and SEO — Not every quote includes copywriting. If you supply the texts yourself, that saves budget — but don't underestimate the time investment. A carefully written services page ranks measurably better in Google than a generic text.

Testing and going live — Professional agencies plan a separate testing phase. Cross-browser, mobile, load time, forms, integrations. This prevents problems from only surfacing after going live.

The hidden costs after going live

A website is not a one-off purchase. What to expect after delivery:

Hosting and domain: €10–€200 per month, depending on complexity and traffic volume.

Maintenance and updates: For a WordPress site, expect €50–€200 per month for plugin updates, security patches, and small adjustments. A custom application needs a separate maintenance contract.

Further development: Once the website is live, the first requests for changes arrive. Expect €2,000–€10,000 per year in further development if the website plays a serious role in your business operations.

SEO and content: A technically good website is the starting point, not the final destination. Structural investment in content and link building determines whether you are actually found.

When is a more expensive website the right choice?

The choice for a higher budget is justified when the website plays a direct role in acquiring or serving customers. A few honest checks:

  • Are you currently losing leads because your website isn't convincing? Then investing in a professional website is almost always profitable.
  • Is your website the primary sales tool? Then a template with limitations is structurally more expensive than a custom approach that you can develop further.
  • Does the website need to integrate with other systems? Then the cheaper segment is in any case technically unsuitable.
  • Do you have a strong brand you want to project? Templates always have a ceiling when it comes to brand experience.

The cheapest website is rarely the cheapest solution in the long run. A poorly built site costs more in maintenance, delivers less result, and needs to be replaced sooner.

How to read a quote properly

Not every quote is equal, even if the final amount is the same. Pay attention to:

  • Specification per phase: a good quote shows how many hours are estimated per phase, not just the total amount.
  • What is included and what is not: copywriting, hosting, SEO, training — is this in the quote or are they separate items?
  • Who builds it: does the agency do the work themselves, or is it outsourced to an offshore team?
  • What are the payment terms: payment in phases based on delivered milestones is the norm at serious agencies.
  • Who owns the code and design: upon delivery, everything must be yours.

Having a website built is an investment in your digital presence. Do it right the first time, and you will benefit from it for years.
