In summary
How much does building a custom website cost in 2026?
A B2B custom website with WordPress without a page builder, Lighthouse 95+ performance, native SEO schema, CRO and server-side attribution costs between €8,000 (corporate website, 8-15 pages) and €28,000 (site with blog, CRO landing pages and A/B framework). A WooCommerce ecommerce starts at €18,000. A Next.js headless site from €28,000. Premium maintenance separate from €720/month.
The real cost depends on 4 variables: number of custom templates, content volume to migrate, integrations (CRM, ERP, payment gateway) and languages. Use the calculator to get a realistic range in 60 seconds. Detailed proposal with breakdown + roadmap in 48 h. No commitment.

Website budget truths 2026
Six things your previous agency didn't tell you about the budget.
A "cheap" Elementor site costs 10× in 3 years via technical debt and LCP > 3 s.
60% of the real cost is not design or code. It's strategy, QA and performance engineering.
Post-signature scope changes = 40-80% average cost overrun. A locked-down discovery prevents it.
Lighthouse < 95 on mobile = 25% lead loss via Core Web Vitals. Invisible but expensive.
Without GrowthBook or an A/B framework, post-launch CRO is guessing. Test infra from day 1.
Premium maintenance costs the same as a technical rescue. Invest > repair in a crisis.
