What does an accessible website cost?

An accessible website costs more than a website without accessibility requirements. An audit often starts in the low four-figure range; the implementation depends on whether accessibility is planned from the start or built into an existing website afterwards.

Accessibility is not a plugin switched on at the end. It affects structure, contrast, keyboard operation, forms, error messages, alternative texts, language, focus handling and technical semantics. The earlier these points are planned in, the less has to be repaired afterwards.

Why accessibility causes extra costs

Additional costs arise from:

• reviewing design, colours, contrast and font sizes
• semantic HTML structure and sensible headings
• keyboard operation and visible focus states
• understandable form labels and error messages
• alternative texts for images and media
• testing with tools, browsers and assistive technologies
• editorial work on understandable content

This work is technically relevant, not just legally. An accessible website is usable by more people and reduces friction in important processes such as inquiry, purchase or application. The matching service page is accessibility.

Retrofit or plan from the start

Planning accessibility from the start is usually cheaper than retrofitting. In a new build, components, colours, forms and templates can be built to fit directly. In an existing site, errors first have to be found, priorities set and technical limits checked.

Retrofitting becomes more expensive when the website depends heavily on page builders, old themes, hard-to-access plugins or external widgets. In that case, a focused relaunch can be more economical than many individual corrections.

What a BFSG audit costs

A BFSG- or WCAG-oriented audit often costs in the low to mid four-figure range, depending on scope. The effort rises with the number of templates, forms, interactive elements, shop steps and third-party functions. These figures are common market reference values and not a fixed offer.

An audit should not just deliver lists of errors. What helps is a prioritised evaluation: which barriers block central uses? What can be fixed quickly? Which points belong in design, development or editing?

Separate the cost question from the obligation question

Whether a website is legally affected is answered in its own question, Is my website subject to the BFSG?. The general website calculation is in the article What does a professional website cost?.

For many companies, accessibility is worthwhile even without an immediate obligation: fewer exclusions, better usability, more robust forms and clearer content.
