How we write and maintain tool content.

Each calculator page is written to explain what the tool does, what inputs it needs, how to read the result, and when the result should be treated as an estimate. We avoid presenting calculators as professional advice.

Finance, health, education, and developer topics can affect important decisions. For that reason, pages include examples, limitations, disclaimers, and links to related tools or guides where useful.

When errors are found, the affected page should be corrected as soon as practical. Users can report unclear wording, broken pages, or calculation concerns through the Contact page.

New tools and guides should be added only when they provide a clear user benefit and enough supporting explanation to be useful on their own.
