Site information
Accessibility
The site aims to provide readable, keyboard-accessible and responsive content with clear headings, labels, focus states, sufficient contrast and print-friendly checklists.
Calculator design
Fields use visible labels, results are announced through live regions, and calculations do not require dragging or precise pointer movement. The tools remain usable at common zoom levels and on small screens.
Known limitations
Complex tables, browser printing, advertising and third-party content may behave differently across devices and assistive technologies.
Feedback
Accessibility barriers may be reported through the restricted contact channel. Include the page address, the barrier encountered and the browser or assistive technology when practical.
