Editorial policy

Advertising and partnerships do not influence what we publish or how content is ordered. We choose topics based only on readers' needs and on content quality, and we never present paid content as editorial content.

We verify information before publishing, show the assumptions behind every calculator, display review dates, and acknowledge the limits of our knowledge when an answer is not clear-cut. Our goal is for readers to see how we arrived at every number.

We do not fabricate statistics, sources, testimonials, people or results. Anything we state is verifiable, or is presented explicitly as an estimate or an opinion.

When a mistake is reported, we investigate and take appropriate action within a reasonable time. If an error is confirmed, we correct it clearly and update the review date. You can report errors through the contact page.

Advertising and affiliate links are disabled by default across the site. If they are ever enabled, they will be labeled consistently and clearly, and they will never influence editorial content or recommendations.

We distinguish between what we know as fact and what is a judgment or estimate. Calculations are built on verifiable formulas, while opinions and estimates are presented in explicit language.
