Accessibility Statement

Last updated: January 1, 2025

Our Commitment

TVM Calculator is committed to ensuring digital accessibility for people with disabilities. We continually improve the user experience for everyone and apply relevant accessibility standards to achieve this goal.

Conformance Status

We aim for conformance with the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA. These guidelines explain how to make web content more accessible to people with disabilities. We are partially conformant — some content may not yet fully meet all success criteria as we continue to improve.

Measures Taken

TVM Calculator takes the following measures to ensure accessibility:

  • Semantic HTML — Proper heading hierarchy, landmark regions (main, nav, header, footer), and descriptive labels on all form inputs.
  • Keyboard navigation — All interactive elements are reachable and operable using a keyboard alone. Focus indicators are visible on all focusable elements.
  • Screen reader support — ARIA labels, roles, and live regions are used to communicate dynamic content changes (calculator results, error messages).
  • Color contrast — Text and interactive elements meet or exceed the WCAG 2.1 AA minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.
  • Responsive design — The Site is fully usable on mobile devices, tablets, and desktops at any screen size.
  • No reliance on color alone — Color is never the sole means of conveying information.
  • Text resizing — Content remains readable and functional when text is resized up to 200% without loss of content or functionality.
  • Reduced motion — Animations are kept minimal and non-essential. Users with prefers-reduced-motion enabled will see reduced animations.
  • Language identification — The lang attribute on the <html> element is set correctly for each supported language.
  • Skip to main content — A skip navigation link is available for keyboard users.
  • Error identification — Form errors are clearly described in text and associated with the relevant input via aria-describedby.

Known Limitations

We are aware of the following areas that may not yet fully meet WCAG 2.1 AA:

  • The visualization bar chart currently does not have a text-based data table alternative. We plan to add one in a future update.
  • Third-party advertising content (Google AdSense) may not fully comply with accessibility standards. This is outside our direct control.

Assistive Technologies Tested

We test with the following assistive technologies:

  • NVDA + Chrome (Windows)
  • VoiceOver + Safari (macOS / iOS)
  • TalkBack + Chrome (Android)
  • Keyboard-only navigation (no mouse)
