Editorial and Corrections Policy

Calculator explanations should be written to clarify the formula, assumptions, and limitations rather than to promote a particular financial product.

Material calculation errors, broken links, and misleading descriptions should be corrected when verified. Significant changes should update the technical review date on the affected page.

Advertising and affiliate relationships, when present, should not determine calculator output. Sponsored content should be identified separately from calculator methodology.
