About

• The honest answer to 'how much does a custom website cost?' is 'it depends', but it depends on a small number of things you can actually quantify. This free web development cost calculator turns those variables into a realistic price range and timeline in under a minute, without the sales call, the pitch deck, or the dreaded 'someone will get back to you within 48 hours.'

• It works for the four projects most people are pricing today: a marketing site, a custom web app, an internal tool, or an integration project. Add the rough number of features, toggle on user accounts, payments, or a custom dashboard, and pick a polish level, MVP, production, or premium. The price range and timeline update live, so you can stress-test a budget before sharing it with anyone else.

• Use this as your sanity check before any agency proposal. If a quote comes in 10× higher than this calculator suggests, ask why. If it comes in 10× lower, ask harder. The numbers reflect what custom web development actually costs in Western Europe right now, not 'it's just a website' wishful thinking.

How much does a custom website cost?

A focused marketing website usually lands between €3,000 and €8,000. A custom web app with login and a couple of dashboards is closer to €15,000–€40,000. A full SaaS MVP, marketplace, or platform typically starts around €25,000 and can go well past €100,000. The calculator above gives a more specific range for what you actually want to build.

How much does a web app cost to build?

Most production-grade web apps with user accounts, payments and a few dashboards land between €15,000 and €50,000. The biggest swings come from how many distinct screens or features you need, whether you want production polish or just an MVP, and whether you need integrations with existing systems.

What makes a web project more expensive?

User accounts, payments, custom dashboards, and integrations with third-party systems are the four biggest cost drivers. After that comes polish: an MVP that 'just works' costs roughly 30% less than a production-grade version with proper design, accessibility, error handling, and edge cases covered. Rush timelines add another 30–40% on top.

Why are agency quotes so different from each other?

Different agencies price for different things: brand-name premiums, dedicated project managers, sales overhead, and how much real engineering time goes into the build. A quote from a 50-person agency and one from an independent specialist can easily differ 3–5× for the same scope. This calculator reflects independent specialist pricing, fair market rate without agency overhead.

Is the timeline realistic?

It's realistic for a focused project with one developer or a small team. Longer projects creep when scope changes mid-build or when stakeholders take days to give feedback. Add a buffer if your organisation is large or if you're not the only decision-maker.

What's not included in the price?

The estimate covers design, development, testing, and launch. It does not include monthly hosting and infrastructure (typically €30–€300/month, see the Solution Blueprint tool), payment processing fees, your domain name, or paid marketing to drive traffic. After the estimate, a 30-minute scoping call works the details into a grounded proposal. That figure can still evolve during the project if the scope or complexity changes.
