Review Policy

Before any new page is published it is reviewed for:

• Mathematical accuracy — the implemented formula matches the one stated on the page, and produces correct results across at least three test cases.
• Source quality — every factual claim ties back to a source listed in our Sources & Methodology page.
• Clarity — a reader without background in the topic can understand what the calculator does and how to use the result.
• Accessibility — semantic HTML, keyboard navigation, screen-reader labels, and sufficient contrast.

Pages don't stop being reviewed after launch:

• Calculators are re-validated at least every 12 months, or sooner whenever a dependency or upstream rate changes.
• Articles are re-read every 12 months for factual drift and updated where the underlying topic has evolved.
• Time-sensitive pages (tax years, statutory rates, currency thresholds) are reviewed at the start of each applicable period.

Reviews are conducted by Calcxo editors with relevant subject expertise. For specialized topics (tax, regulated health metrics, advanced finance) we consult external experts and credit them on the page where appropriate. No author reviews their own work for publication.

Reader reports, formula changes, regulatory updates, and unexpected analytics signals (e.g. an unusually high bounce rate on a result page) all trigger an immediate re-review outside the normal cadence.

If a review uncovers an error, the page is corrected as soon as the fix is verified, the Last updated date changes, and a short note describing the correction is appended to the page when results were affected. To report an issue, email corrections@calcxo.com.
