Corrections Policy

Accuracy matters—and so does correcting mistakes clearly.

At 365Calcs, we aim to provide reliable calculators supported by appropriate formulas, clear assumptions, and understandable explanations.

Despite careful testing, an error, outdated value, or unclear explanation may occasionally appear. This policy explains how issues can be reported, reviewed, and corrected.

What can be reported?

You can report any issue affecting the accuracy or interpretation of our content, including:

  • Incorrect formulas or results
  • Unit conversion or rounding errors
  • Outdated reference values
  • Missing or unclear assumptions
  • Misleading explanations
  • Broken calculator functionality
  • Incorrect links or factual information

How to report an issue

Please use our reporting form and provide as much relevant information as possible:

  • The calculator's name or URL
  • The values and units entered
  • The result received
  • The result expected
  • A description of the possible issue
  • Any supporting formula or clear explanation

Please do not include confidential, medical, financial, or otherwise sensitive personal information.

Report an issue

How reports are reviewed

When we receive a report, we attempt to reproduce the issue using the information provided.

Depending on the report, we may:

  • Review the formula and calculation logic
  • Recalculate the result independently
  • Test unit conversions and rounding
  • Compare the method with recognized guidance
  • Review assumptions, labels, and explanations
  • Test additional values and edge cases

Different results do not always indicate an error. Calculators may use different formulas, assumptions, standards, or rounding methods. In these cases, we may clarify the method used instead of changing the calculation.

How corrections are prioritized

Issues are prioritized according to their potential impact.

Errors affecting health, safety, finance, legal obligations, or a significant number of users receive greater priority. Problems that materially change a result are also prioritized over cosmetic or formatting issues.

When an error is confirmed

We correct the affected formula, value, conversion, explanation, or interface and test the updated calculator before publication.

For material corrections, we may display:

  • The date of the correction
  • A short explanation of what changed
  • Whether previous results may have been affected
  • Any updated formula, assumption, or supporting evidence

Minor changes that do not affect a calculator's result—such as spelling, formatting, clearer labels, or updated links—may be made without a formal correction notice.

Updates are not always corrections

Some calculators rely on standards, regulations, recommendations, or reference values that change over time.

Updating a calculator to reflect new information does not necessarily mean the previous version contained an error. Where relevant, the calculator page may display its latest review or update date.

Our commitment

We do not knowingly leave confirmed calculation errors unresolved.

When a meaningful issue is identified, our goal is to investigate it carefully, correct it promptly, test the updated version, and explain material changes when appropriate.

Your feedback helps us make 365Calcs more reliable for everyone.
