Editorial Policy

Calc Hub keeps calculator pages practical, transparent, and estimate-first.

How formulas are verified

Calculator formulas are implemented from documented assumptions, source references, or standard equations. When a tool depends on tax years, material factors, or reference ranges, the page notes the relevant assumptions.

How calculators are tested

Core formulas are covered by focused unit tests where edge cases matter. Interactive tools are checked for mobile layout, visible results, and route discoverability.

How content is reviewed

Support pages are written to explain what the calculator does, what inputs mean, and where results should be treated as estimates rather than professional advice.

How updates are published

Updates are shipped when formulas, source data, UX issues, or user requests require changes. Major calculator changes are paired with documentation updates under /docs.

Calculator results are for education and planning. Financial, medical, legal, tax, construction, and electrical decisions should be reviewed with qualified professionals when accuracy matters.
