Web accessibility costs vary enormously depending on approach: a widget subscription typically runs from free or a few dollars a month up to a few hundred dollars monthly depending on site size, while a proper manual audit is usually a separate engagement priced from a few thousand dollars for a small site into six figures for a large, complex enterprise property. There’s no single “accessibility costs $X” answer, because the real cost depends on which combination of tools and services you actually need.

That range is wide enough to be frustrating if you’re trying to budget precisely, but it’s wide for a legitimate reason: a five-page brochure site and a multi-region e-commerce platform are not remotely the same scope of work, even though both technically fall under “web accessibility.” The rest of this guide breaks the cost down by category so you can place your own situation somewhere on that spectrum rather than anchoring on a single headline number.

Widget and overlay pricing

Widgets are almost always priced as an ongoing subscription tied to site size, traffic, or number of domains, rather than a one-time fee. UserWay offers a free tier aimed at very small sites, with paid tiers unlocking more automated checks. Accessi+ positions itself specifically as a low-cost, low-friction option for small business sites. Wawsome offers a free trial period before moving to paid subscription tiers, with pricing that requires a separate subscription per subdomain. EqualWeb spans a particularly wide pricing range, from small single-site plans up to large enterprise, multi-domain agreements, reflecting how differently the same core product can be priced depending on who’s buying it.

The pattern across the category: entry-level widget pricing is genuinely accessible to small businesses, but the free or cheapest tiers tend to cover a narrower slice of functionality (basic display adjustments, limited automated remediation) than the paid tiers built for larger or more compliance-sensitive customers.

Manual audit and remediation pricing

Manual audits don’t follow a simple pricing formula the way widgets do, because the cost scales with how many pages, templates, and user flows need to be tested, and how deep the testing goes (automated-tool-assisted review versus full manual testing with actual assistive technology users). A small marketing site with a handful of page templates might be a few thousand dollars for a focused audit. A large e-commerce platform or a complex enterprise application with dozens of unique flows can run substantially higher, especially once you add remediation (someone actually fixing the code, not just reporting on it) rather than just an audit report.

It’s worth distinguishing between an audit and remediation as separate line items, since vendors sometimes bundle them and sometimes don’t. An audit alone gets you a report; remediation is the actual development work of implementing the fixes it identifies. If a quote seems unusually low for a full audit-and-fix engagement, it’s worth confirming exactly which of the two you’re actually being quoted for, since a report with no implementation help doesn’t move the needle on your site’s actual accessibility until someone does something with it.

Vendors like EqualWeb offer manual remediation as a distinct paid service alongside their widget, letting a business layer deeper work on top of a lower base cost. Allyant, which focuses specifically on large-scale document and PDF remediation for enterprises and government agencies, prices its engagements per document volume or project scope, reflecting how specialized and labor-intensive that particular category of work is.

What drives the cost up or down

A few factors matter more than which specific vendor you pick. Site complexity is the biggest one: a static informational site is a fundamentally different scope than an e-commerce checkout flow with custom components, dynamic filtering, and a multi-step form. Existing code quality matters too, since a site with a strong accessible foundation from the start needs far less remediation work than one with years of ad-hoc, inaccessible components layered on top of each other. And how many standards you need to satisfy at once (WCAG 2.1 AA alone versus WCAG plus EN 301 549 plus a formal VPAT for procurement) changes the scope of documentation required, which is its own cost driver separate from the technical fixes.

Ongoing maintenance is a cost category that’s easy to underbudget for. A site that passes an audit today doesn’t stay compliant automatically as new pages, product listings, or marketing campaigns get published; each new piece of content can reintroduce the same kinds of issues that were just fixed. Budgeting for some recurring monitoring or a periodic re-check, rather than treating the initial audit as a one-time expense, tends to be cheaper over a multi-year horizon than letting the gap widen again and paying for a second full remediation project later.

Free and low-cost starting points

For businesses with genuinely minimal budget, it’s worth being clear-eyed about what free actually covers. UserWay’s free tier and similar entry-level offerings from other vendors typically give a small site basic display adjustments and some automated checks, which is a real improvement over nothing, but it’s not equivalent to a paid tier’s fuller automated remediation, let alone a manual audit. A free trial period, like the one Wawsome offers before its paid tiers begin, is useful for evaluating a tool’s fit before committing budget, but it’s a trial window rather than a long-term free option. Treat free and low-cost tools as a genuine first step worth taking, not as a finish line.

The cost of doing nothing

It’s worth weighing accessibility spend against the cost of skipping it, even though there’s no single tidy figure that captures this. On the EU side, EAA non-compliance carries reported maximum fines ranging from roughly €60,000 to around €900,000 depending on the member state, plus the possibility of product withdrawal or a market ban. On the US side, ADA-related demand letters and litigation carry their own legal costs regardless of outcome. And the underlying problem these figures point to is genuinely widespread: the 2026 WebAIM Million report found 95.9% of home pages had at least one detectable WCAG failure, meaning most businesses that haven’t budgeted for accessibility work are carrying real exposure whether or not they’ve been contacted about it yet.

A practical way to budget

Rather than picking a number out of the air, start by getting a scoped quote for a manual audit of your actual site, then decide how much of the resulting fix list you can absorb with in-house development time versus paying a vendor to implement. Layer a widget subscription on top for ongoing display adjustments and monitoring, not as a substitute for the audit findings.

Treat the first year’s budget as necessarily higher than subsequent years, since most of the structural remediation work is front-loaded once you actually address a backlog of existing issues. A site that’s been running for several years without any accessibility attention typically needs a larger initial push than a newer site built with at least some accessibility consideration from the start; year two and beyond usually settles into a lower, steadier cost focused on monitoring and catching new issues as content gets added, rather than repeating a full remediation project.
