Corrections Policy

How to report an error

If you spot a formula mistake, a broken example, an unclear explanation, or an outdated source reference, please let us know through the Contact page.

What we review

• Incorrect formulas or unit conversions
• Descriptions that do not match the calculator output
• Broken links, missing sections, or rendering problems
• Outdated information or stale references on time-sensitive pages
• High-risk content that should be noindexed or restricted

How corrections are made

Confirmed issues are fixed in the source page or supporting content, and the page's update date is changed when the visible content changes. If a page needs deeper review, we may add a note, remove it from the sitemap, or apply noindex until the issue is resolved.

Important note

We do not claim professional review unless it has actually occurred. For financial, medical, legal, or tax questions, calculator results remain informational estimates only.
