- Visualize the data: Use charts and graphs to help users understand the results at a glance.
- Provide actionable insights: Don’t just show numbers—explain what they mean and what actions users can take.
- Make it shareable: Allow users to save or share their calculations via email or social media.
- Ensure accessibility: Follow WCAG guidelines so your calculator can be used by everyone, including those with disabilities.
