Trust center

Useful first. Transparent always.

The editorial standard is simple: a tool must help a contractor make a clearer decision even if no one clicks anything afterward.

Independence

Monetization does not change formulas or inflate results. Partners do not receive favorable assumptions, hidden placement, or access to the values entered into a calculator.

Accuracy

Every published calculation has a visible formula, a worked example, bounded inputs, and tested fixtures. Time-sensitive claims require a dated source and scheduled review.

Corrections

Material errors are corrected promptly and recorded in the formula release notes. Reports should identify the calculator, inputs, expected result, and source or reasoning supporting the correction.

AI use

Automation may assist research, drafting, testing, and production. Published formulas, claims, and recommendations remain subject to source checks and human-responsible editorial standards.
