Editorial Policy

Last reviewed: July 21, 2026

Who creates our content

Articles are published by the Free Calculator Hub Editorial Team. This shared byline does not imply medical, financial, legal, or other professional credentials. We name external reviewers only with permission and accurately state their review scope.

Source standards

We prefer government agencies, standards bodies, original peer-reviewed research, recognized professional organizations, and official technical documentation. Material factual claims should be traceable to a source.

Review dates and updates

We prioritize re-review when formulas, official guidance, laws, rates, or important evidence change. Minor spelling fixes may not change the review date.

High-impact topics

Health, finance, tax, credit, legal, and insurance content receives extra scrutiny. Results are educational estimates, not diagnoses or individualized professional advice.

Commercial independence

Advertising, affiliate relationships, and lead-generation arrangements never determine calculator results or editorial conclusions. Commercial placements must be clearly disclosed.
