The verdict in three sentences
Since 2025-2026, any company above 250M EUR revenue (and many players under the European Accessibility Act) must make its digital services WCAG 2.1 AA compliant. An initial audit costs 2,500 to 6,000 EUR (approx. USD 2,700-6,500), and remediation adds 10-20% to the development budget. Fines can reach 50,000 EUR and carry a serious reputational risk.
What the law really requires
Accessibility is more than a badge. You need a published accessibility statement, a multi-year plan, a displayed compliance rate and a contact mechanism. The WCAG 2.1 AA standard has 50 success criteria (106 test criteria under RGAA). Here are the cost items by target level.
| Compliance level | Scope | Audit cost (EUR) | Remediation cost (EUR) |
|---|---|---|---|
| Initial audit only | Full criteria diagnostic | 2,500 - 6,000 | - |
| Partial compliance (~75%) | Priority fixes | 3,000 | 6,000 - 12,000 |
| Full AA compliance | All blocking criteria | 5,000 | 12,000 - 25,000 |
| Accessibility + ongoing upkeep | AA + annual audits | 5,000 + 2,500/yr | 15,000 - 30,000 |
The criteria that fail most often
Some criteria appear systematically in audits and concentrate most of the fixes. Anticipating them at the design stage avoids retrofitting that costs 2-3 times more.
| Key criterion | Frequency of failures | Fix effort |
|---|---|---|
| Insufficient color contrast | Very high | Low to medium |
| Image text alternatives | High | Medium |
| Full keyboard navigation | High | High |
| Labeled forms | Medium | Medium |
| Consistent heading structure | Medium | Low |
| Correct ARIA components | Medium | High |

Claire, CFO of a retail group (310M EUR revenue), must bring its corporate site into compliance. Initial audit at 5,000 EUR, then full AA remediation at 18,000 EUR, i.e. 23,000 EUR in year one, plus 2,500 EUR/year upkeep. Against a 50,000 EUR fine risk and the potential loss of public tenders requiring accessibility, the investment is defensive as much as ethical: it secures roughly 8% of revenue tied to compliance-conditional contracts.
FAQ
Is my company subject to the obligation? Companies above 250M EUR revenue and many e-commerce, banking, transport and telecom players are targeted by the European Accessibility Act. When in doubt, a 1,500 EUR pre-diagnostic settles the question.
What does a WCAG 2.1 AA audit cost? Between 2,500 and 6,000 EUR depending on the number of pages and components assessed. A 30-50 page site sits around 4,000 EUR.
What is the risk of non-compliance? Financial penalties up to 50,000 EUR, exclusion from certain tenders and reputational risk. The cost of compliance stays far below the cost of the risk.
Is it better to build accessibility in from the start? Yes: designed upfront, accessibility adds 10-15% to the budget. Retrofitted on an existing site, it can cost 2-3 times more.
Do we need an audit every year? To maintain compliance as the site evolves, an annual audit at around 2,500 EUR is recommended, complemented by continuous automated checks.
