Accessibility Remediation Cost Calculator

An accessibility remediation cost calculator estimates the effort and budget required to fix the accessibility problems on a website, so teams can plan and scope the work before committing to a fixed quote. Rather than counting every individual page, it works at the level of page templates — the reusable layouts (home, product, article, checkout, account) that generate the hundreds or thousands of pages a site actually serves. Because a single template fix propagates across every page built from it, template count is a far better basis for estimating real effort than raw page count.

The model multiplies your number of unique templates by the average number of accessibility issues found per template to get a total issue count. That total is multiplied by the average time it takes a developer to fix one issue — some fixes, like adding alt text or a form label, take minutes, while others, like rebuilding a custom dropdown for full keyboard and screen-reader support, take hours, so the average smooths across the mix. The resulting base hours are then increased by a testing and retest overhead, because real remediation is never write-once: every fix has to be verified with automated tools and manual assistive-technology testing, and a meaningful share of fixes fail retest and need a second pass. Multiplying the adjusted hours by a blended hourly rate produces the total cost, which is also broken down per template so you can prioritize the highest-traffic or highest-risk layouts first.

Two cautions matter. First, this is an estimate of engineering effort, not a compliance guarantee — it makes no claim that the result will satisfy WCAG, the ADA, or the European EN 301 549 standard, all of which require judgment and testing beyond a page count. Second, the input that moves the number most is issues per template, which only a real automated-plus-manual audit can pin down; treat the default as a placeholder until you have audit data. Used with those caveats, the calculator turns an open-ended remediation project into a scoped, defensible budget and timeline you can take to stakeholders.
