See how BizCalcAtlas formulas, sources, assumptions, tests and review rules are used to build and maintain transparent U.S. business calculators.
Formula hierarchy
Calculator logic follows the audited implementation package in this order: Step 4.6 dynamic-data decisions, Audit 110, Build Specs 110, then Formula Archetypes. Lower-priority material cannot override a higher-priority decision.
Sources and calculations
Definitions favor authoritative U.S. government, standards, or first-party platform sources. Inputs are normalized before calculation, denominators and invalid ranges fail visibly, and results retain full precision until display rounding.
Testing
Every calculator definition is paired with normal and boundary coverage where the audited implementation package provides it. Automated regression checks compare expected outputs and validation states and also verify routes, canonicals, sitemap membership, internal links, structured data, accessibility, privacy, bundle budgets, and release blockers.
Automation, AI, and editorial responsibility
Automation or AI may assist drafting, organization, source grouping, and regression work. It is not treated as an authoritative source and cannot override the audited formula, official rate registry, source hierarchy, or a blocked release decision. MIASIN S.R.O. controls publication, corrections, and release decisions; no named individual expert review is claimed unless a page explicitly identifies one.
Review evidence
Calculator and guide pages show their last-reviewed date, source-review or source-verification date, next scheduled review, and page-specific testing summary. See Sources & References for the source tiers and Corrections Policy for the correction workflow.
Limitations
No calculator predicts demand, guarantees an outcome, or replaces context-specific advice. Dynamic fees can change between scheduled reviews.
