Editorial Methodology

How this site researches and corrects calculators

Authorship and maintenance

Calculator News is maintained by David K..

Public pages are reviewed in the repository, tested where practical, and updated when a formula defect, wording problem, or stale external reference is confirmed.

What gets sourced

  • AI pricing pages link to the provider pricing or model documentation used for the listed rate card.
  • Finance pages cite public sources for externally derived assumptions such as debt-to-income guidelines.
  • Solar pages identify the incentive and methodology assumptions that materially affect the estimate.

Testing and correction process

  1. Confirm the formula or behavior against the page method and the supporting source.
  2. Update the implementation and add or revise automated tests when the bug is deterministic.
  3. Review the surrounding content so the explanation and disclaimer still match the behavior.
  4. Publish the change with a refreshed review date when the page meaningfully changes.

How to report an error

Use the contact page or request form and include the page URL, your inputs, the output you saw, and the reason you think it is wrong.

If the issue depends on a third-party source, include the source link you believe the page should match.
