Corrections Policy

Accuracy problems should be easy to report and reproducible. SopidoCalc accepts correction reports for formulas, input validation, output formatting, worked examples, sources, accessibility, links and editorial claims.

How to report an issue

Email info@sopidocalc.com or use the contact page. Include the calculator URL, the exact inputs you used, the result you received, the result you expected, and any authoritative reference that helps explain the difference. Do not include passwords or unnecessary sensitive information.

How reports are reviewed

We aim to reproduce the issue first. A calculation defect is checked against the implemented method and, where appropriate, an independent reference. Content issues are checked against the cited or current authoritative source. Broken links and accessibility defects are verified on the affected route and component.

What happens after a confirmed error

The formula, validation rule, source, example or explanation should be corrected at the narrowest appropriate layer, followed by regression testing of the affected calculator family. Material changes to time-sensitive or consequential tools should also trigger a review-date update.

Disagreements and estimates

Two calculators can legitimately disagree when they use different definitions, rounding rules, rate dates or assumptions. If the SopidoCalc method is valid but the distinction is not clear, the page should be improved to explain the difference rather than silently changing the calculation.
