Corrections Policy & Log
CalcPlanet calculators are used for real decisions about money, health and projects, so a wrong result matters. This page explains how the CalcPlanet Editorial Team handles reported errors and keeps a dated record of every correction we publish. Policy last updated: 2026-09-30.
What counts as a correction
- A calculator returns a wrong result for valid inputs, or rounds in a misleading way.
- A formula, constant, tax bracket, fee or rate shown on a page is incorrect or out of date.
- A worked example, FAQ answer or guide contains a factual or arithmetic mistake.
- A unit, currency or label is wrong (for example a metric value labeled as imperial).
Typo fixes, layout changes and wording improvements that do not change meaning are not logged as corrections.
How to report an error
Email info@calcplanet.com or use the contact page. Please include the page address, the inputs you entered, the result you saw and the result you expected, plus a source if you have one.
How reports are reviewed and corrected
- Every report is read and the calculation is reproduced with the same inputs.
- The formula is checked against the primary source listed on the page or in our formula sourcing documentation.
- If the page is wrong, the formula or content is fixed, an automated regression test is added where possible, and the page's review date is updated.
- Material corrections are added to the log below with the date, the page and a plain-language summary.
- If the page is correct, we reply explaining the method and the source used.
