Accessibility
The answer should be usable on a phone, with a keyboard, or with assistive technology.
Navigate with a keyboard
Use the skip link to reach the page content. Tab moves between labelled fields and controls. The place picker supports search, arrow keys, Enter to choose and Escape to close. Native disclosures open with Enter or Space.
Read the result
Every chart amount also appears as text. Pension accrual is identified with a hatch and an explanation. Estimates have a text label, so colour is not the only way to distinguish them. You can enlarge the page using browser zoom.
Forms and feedback
Money fields accept a decimal comma or point. Invalid edits show an explanation after you leave the field; the previous valid calculation remains visible. Sharing and reporting announce completion or failure.
Limits
This is a review implementation, not a claim of formal accessibility certification. The app requires JavaScript for interactive calculation and sharing; the default example and source content are available as static HTML.
How this is worked out
Can I use the figures without reading the chart?
Yes. The gross salary, deductions and net amount are printed beside the bars. The chart is a visual aid, not the only way to read the answer.
