Editorial Policy

Content principles

Explanations should be practical, readable, and directly related to the associated tool. We avoid presenting estimates as guarantees.

Sources and formulas

Where a calculation relies on a recognized formula, the guide explains the inputs and assumptions. Time-sensitive rules, rates, and regulations require current authoritative sources before publication.

Corrections

Material errors should be corrected promptly. Significant platform changes are recorded on the changelog page.

Commercial separation

Future sponsored or affiliate content will be clearly disclosed and will not alter calculator results.
