Editorial Policy

How we research, explain, check, and correct calculator pages.

Last reviewed: October 2026

What each guide is meant to do

A MiniCalculators guide should help a reader understand the calculation, not simply produce a number. We explain the inputs, formula or method, units, a worked example, practical uses, common mistakes, and the limits of the result. Wording is written for the calculator at hand rather than copied between topics.

Sources and formulas

We prefer primary or official references when they are available, including government agencies, standards bodies, universities, and original technical publications. Some everyday conversions and established mathematical formulas are also checked against reputable reference material. A source link supports the explanation; it does not mean that the source endorses MiniCalculators.

How pages are checked

We compare the written formula with the calculator's implemented method and use worked examples to check expected outputs. Automated checks also look for missing guide sections, broken page structure, duplicate metadata, and calculator pages that cannot be rendered. We review reported errors and update a page when its formula, wording, source, or implementation needs correction.

Health and financial topics

These calculators provide educational estimates. A formula cannot account for every personal circumstance, local rule, fee, clinical finding, or professional judgment. Health tools do not diagnose or recommend treatment, and financial tools do not provide financial, tax, or legal advice. Important decisions should be checked with a suitably qualified professional.

Corrections

If a result, formula, explanation, or source appears wrong, email support@minicalculators.com. Include the page URL, the inputs used, and what you expected to see. Clear reports make it easier to reproduce and correct a problem.
