How Much Does an Accessibility Audit and WCAG Remediation Cost?

Before talking numbers, you need to understand what you are buying. An accessibility audit is a systematic evaluation of your digital product against the Web Content Accessibility Guidelines (WCAG), typically at the 2.1 AA or 2.2 AA conformance level. The deliverable is a detailed report listing every violation, its severity, the specific WCAG criterion it fails, and recommended fixes.

A proper audit combines automated scanning with manual expert testing. Automated tools like axe-core, WAVE, and Lighthouse catch roughly 30% of accessibility issues: missing alt text, low color contrast, empty form labels, broken ARIA attributes. The remaining 70% requires a human expert navigating your product with a screen reader, keyboard-only input, and assistive technologies to evaluate things like logical reading order, focus management in modals, and whether custom components actually work for disabled users.

Most audits also include a sampling strategy. If your product has 500 pages, nobody is testing all 500 individually. Auditors select a representative sample of page templates, user flows (signup, checkout, dashboard, settings), and component types. The sample size directly affects cost. A 10-page audit of a marketing site is a very different engagement than a 60-page audit of a SaaS platform with role-based dashboards, data tables, and interactive charts.

You should also know the difference between a conformance audit and a usability audit. A conformance audit checks boxes against WCAG criteria. A usability audit goes further by involving actual disabled users who test your product and provide qualitative feedback. The usability approach costs more but catches problems that even expert reviewers miss, like confusing workflows that technically pass WCAG but are miserable to use with a screen reader.

Here are the real numbers we have seen across dozens of projects and vendor proposals. These ranges reflect 2030 market pricing from US-based firms, and costs can be 30% to 50% lower with qualified offshore teams.

Automated Scan Only: $0 to $500

Running axe DevTools, WAVE, or Lighthouse across your site is essentially free if you do it yourself. Some vendors offer automated scanning as a service for $200 to $500, which adds a formatted report and prioritized issue list. This is a starting point, not a real audit. It catches surface-level problems but misses the majority of accessibility barriers. Think of it as a smoke test.

Lightweight Manual Audit (10 to 20 Pages): $3,000 to $8,000

This covers a small marketing site or a focused slice of a larger product. An accessibility consultant spends 20 to 40 hours reviewing key page templates, testing with NVDA or VoiceOver, and documenting findings. You get a report with 50 to 150 individual issues, each mapped to a WCAG criterion with a severity rating. Freelance specialists on the lower end, boutique agencies on the higher end.

Comprehensive Audit (30 to 60 Pages): $8,000 to $25,000

This is the standard engagement for a SaaS product or complex web application. The auditor reviews all unique page templates, major user flows, and interactive components. Expect 100 to 300+ documented issues. Firms like Level Access, Deque, and TPGi typically quote in this range. The engagement includes a kickoff call, the audit itself (2 to 4 weeks), a detailed report, and a findings walkthrough session with your team.

Enterprise Audit with User Testing: $20,000 to $50,000+

Large organizations with multiple products, native mobile apps, and complex workflows need broader coverage. This tier often includes testing with disabled users (typically 5 to 8 participants), PDF and document accessibility review, and a remediation roadmap with effort estimates. Some enterprise contracts also bundle training workshops for your design and engineering teams.

One pattern we see repeatedly: companies spend $15,000 on an audit, get a 200-issue report, and then realize they have no budget left for actually fixing anything. Allocate your audit budget at roughly 20% to 30% of your total accessibility investment. The rest goes to remediation.

The audit tells you what is broken. Remediation is the work of fixing it. This is where budgets either stretch or collapse, depending on how your product was built and how severe the violations are.

Quick Wins and Low-Hanging Fruit: $2,000 to $8,000

Many WCAG violations are trivial to fix once identified. Adding alt text to images, increasing color contrast ratios, associating labels with form inputs, adding lang attributes, fixing heading hierarchy. A competent front-end developer can knock out 50 to 80 of these issues in a week or two. If your audit found mostly these types of problems, you are in good shape.

Component-Level Remediation: $10,000 to $40,000

This is the mid-tier work. Custom dropdown menus that lack keyboard support need to be rebuilt with proper ARIA roles, states, and keyboard event handlers. Modal dialogs that do not trap focus require rearchitecting. Data tables missing proper header associations need structural changes. Each broken component takes 4 to 16 hours to fix properly, and most products have 10 to 30 components that need attention. If you are using a component library like Material UI or Chakra UI, some of this work is handled by upgrading to newer versions that ship with better accessibility defaults.

Structural Overhaul: $30,000 to $100,000+

Some products have accessibility problems baked into their architecture. Single-page applications that do not announce route changes to screen readers. Client-side rendering that produces inaccessible DOM structures. Drag-and-drop interfaces with no keyboard alternative. Canvas-based data visualizations with no text fallback. These require significant engineering effort. In the worst cases, entire features need to be rebuilt. We have seen mobile app redesign projects where accessibility remediation accounted for 40% of the total rebuild budget because the original codebase was so deeply inaccessible.

Partial vs. Full Remediation

Many teams adopt a phased approach. Phase 1 fixes all critical and serious violations (WCAG Level A failures and high-impact AA failures) for $10,000 to $25,000. Phase 2 addresses remaining AA violations over the next quarter for another $15,000 to $35,000. This spreads the cost and lets you ship meaningful improvements quickly. Full remediation to WCAG 2.2 AA for a medium-complexity web app typically lands between $25,000 and $75,000 all-in, including the audit.

The platform your product runs on significantly affects both audit and remediation costs. Each platform has its own accessibility APIs, testing tools, and common pitfalls.

Web Applications: $8,000 to $60,000 Total

Web is the most mature platform for accessibility tooling and standards. WCAG was written for the web, and the ecosystem of testing tools (axe, WAVE, Lighthouse, Pa11y) is robust. Most accessibility consultants have deep web expertise. The cost range depends on complexity: a 20-page marketing site on the low end, a full SaaS platform with interactive dashboards on the high end. React, Angular, and Vue applications tend to cost more to remediate than static sites because of their reliance on custom components and client-side routing.

Native Mobile Apps (iOS and Android): $15,000 to $80,000 Total

Mobile accessibility is governed by platform-specific guidelines in addition to WCAG. iOS uses VoiceOver and the UIAccessibility API. Android uses TalkBack and the Accessibility framework. An audit must cover both platforms separately, and remediation requires platform-specific fixes. Mobile apps also have unique challenges: gesture-based interactions need alternatives, touch targets must meet minimum size requirements (48x48 dp on Android, 44x44 pt on iOS), and dynamic content updates need proper accessibility announcements. The pool of consultants with deep mobile accessibility expertise is smaller than for web, which pushes prices higher.

Multi-Platform Products: $25,000 to $120,000+ Total

If you have a responsive web app, an iOS app, and an Android app, you are looking at three separate audit and remediation workstreams. Cross-platform frameworks like React Native and Flutter introduce their own accessibility quirks. React Native's accessibility props do not always map cleanly to native accessibility APIs, which creates issues that only appear on one platform. Budget for platform-specific testing even if you share a codebase.

One cost-saving strategy: if you are planning a UX/UI design overhaul anyway, bundle accessibility remediation into that project. Redesigning components from scratch with accessibility built in is often cheaper than retrofitting an existing inaccessible codebase.

Accessibility is no longer optional in most major markets. The legal pressure is real, and the financial penalties for ignoring it are significant.

ADA in the United States

The Americans with Disabilities Act does not explicitly mention websites, but courts have consistently ruled that digital properties qualify as "places of public accommodation" under Title III. ADA website lawsuits exceeded 4,600 in 2029, up from about 2,300 in 2023. The average settlement for a first-time ADA web accessibility lawsuit ranges from $5,000 to $25,000 for small businesses and $50,000 to $150,000 for larger companies. Repeat offenders face higher penalties. Legal fees alone can run $10,000 to $50,000 even if you settle quickly. Compare that to the $15,000 to $40,000 it costs to proactively audit and fix your site, and the math is obvious.

European Accessibility Act (EAA)

The EAA took effect in June 2025 and applies to any business selling digital products or services in the EU, regardless of where the company is headquartered. It mandates WCAG 2.1 AA compliance for websites, mobile apps, e-commerce platforms, e-books, and banking services. Penalties vary by member state but can reach up to 5% of annual revenue in some jurisdictions. If you sell to European customers, this is not something you can defer.

Section 508 and Government Contracts

Any organization that does business with the US federal government must comply with Section 508, which references WCAG 2.0 AA (and increasingly WCAG 2.1 AA in updated procurement language). Non-compliance can disqualify you from government contracts entirely. For B2B SaaS companies targeting enterprise and government buyers, a VPAT (Voluntary Product Accessibility Statement) documenting your compliance status is a standard procurement requirement.

The trend is clear: every year, more jurisdictions add digital accessibility requirements, enforcement intensifies, and the cost of being caught non-compliant increases. Treating accessibility as a proactive investment rather than a reactive legal expense saves you money in every scenario.

The accessibility market has matured significantly. You have options ranging from free open-source tools to full-service consultancies. Here is how they stack up.

Free and Low-Cost Tools

axe-core by Deque is the open-source engine that powers most accessibility testing tools. It is free, integrates into CI/CD pipelines, and catches about 57% of common WCAG violations automatically. The axe DevTools browser extension adds guided manual testing on top. Free for basic use, $5,000 to $12,000 per year for the enterprise version with issue tracking and reporting.

WAVE by WebAIM is a free browser extension and online tool that provides visual overlays highlighting accessibility issues directly on your page. It is excellent for quick evaluations and for showing non-technical stakeholders what is wrong. The WAVE API for automated scanning starts at $1,000 per year.

Pa11y is an open-source command-line tool and CI runner for automated accessibility testing. It is completely free and works well for teams that want to add accessibility gates to their deployment pipeline without vendor lock-in.

Mid-Range Vendors and Platforms

Siteimprove offers a platform that combines automated scanning with content quality and SEO monitoring. Accessibility plans start around $5,000 to $15,000 per year depending on the number of pages. Good for marketing teams that want a dashboard view of their compliance status.

AudioEye and UserWay sell overlay widgets that attempt to fix accessibility issues on the client side using JavaScript. Pricing ranges from $500 to $5,000 per year. We strongly advise against relying on overlays as your primary compliance strategy. They do not fix underlying code issues, they frequently break page functionality, and several have been named as defendants in accessibility lawsuits. The National Federation of the Blind has publicly opposed overlay products. Use them only as a temporary stopgap while you do proper remediation.

Full-Service Consultancies

Level Access (formerly SSB BART Group) is one of the largest accessibility firms in the US. They offer audits, remediation support, training, and managed monitoring. Enterprise contracts typically start at $30,000 to $50,000 per year. They are thorough but expensive, best suited for organizations with complex compliance needs.

Deque Systems builds axe and also offers consulting services. Their audits are technically rigorous, and their team includes some of the people who write the WCAG specification. Audit engagements start around $15,000. They are a good fit for engineering-driven organizations that want actionable, developer-friendly reports.

TPGi (The Paciello Group, now part of Vispero) has been in accessibility consulting for over 20 years. They are well-known for their expertise in complex enterprise environments, PDF accessibility, and assistive technology compatibility testing. Audit pricing is comparable to Deque.

For startups and mid-market companies, our recommendation is to combine free tools (axe-core in CI, WAVE for spot checks) with a focused engagement from a specialist consultancy for the initial audit and remediation plan. You do not need a $50,000-per-year managed service contract. You need one solid audit, a clear remediation backlog, and internal processes to maintain compliance going forward.

Knowing the cost is only half the picture. You also need to know how long this takes and what happens after the initial push.

Typical Project Timelines

A lightweight audit of a small site takes 1 to 2 weeks. A comprehensive audit of a complex application takes 3 to 6 weeks. Remediation timelines depend entirely on severity and engineering capacity, but a realistic range for most products is 2 to 4 months for Phase 1 (critical and serious issues) and an additional 2 to 3 months for Phase 2 (moderate and minor issues). Do not let a vendor tell you they can audit and fully remediate a 50-page application in two weeks. That is not a serious engagement.

Ongoing Maintenance Costs

Accessibility is not a one-time project. Every new feature, every design update, every content change can introduce new violations. Budget $5,000 to $15,000 per year for ongoing accessibility maintenance. This covers quarterly automated scans, annual manual re-audits of major flows, and developer training. Some teams embed accessibility QA into their sprint process, which adds roughly 10% to 15% to feature development time but prevents the accumulation of accessibility debt.

The most cost-effective approach is building accessibility checks into your CI/CD pipeline. axe-core running in your test suite catches regressions automatically. eslint-plugin-jsx-a11y flags issues at the code level. These tools are free and prevent the cycle of "audit, fix everything, let it degrade, audit again" that burns money year after year.

The ROI Case

Beyond lawsuit avoidance, accessible products perform better across multiple dimensions. Users with disabilities represent over 15% of the global population and control $13 trillion in annual disposable income. Accessible websites tend to have better SEO because search engines parse semantic HTML the same way screen readers do. Keyboard navigability improves power user productivity. Proper color contrast improves readability for everyone, not just visually impaired users.

Companies that have invested in accessibility consistently report higher customer satisfaction scores, lower support ticket volume (because the product is easier to use), and improved conversion rates. Microsoft, Apple, and Google all publish accessibility as a competitive differentiator, not a compliance burden. For a mid-market SaaS company, the math typically works out to a 3x to 5x return on your accessibility investment within the first two years when you factor in avoided legal costs, expanded market reach, and reduced support overhead.

If you are unsure where to start, the most efficient path is a focused audit of your highest-traffic pages and core user flows, followed by phased remediation that tackles critical issues first. You do not need to achieve perfect compliance overnight. You need a plan, a timeline, and forward momentum.
