Editorial policy

Primary sources first

Time-sensitive claims are checked against regulators, public authorities, official statistics or the issuing institution. Secondary summaries are used only for orientation, not as the canonical citation where a primary source exists.

Transparent assumptions

Calculator examples are labelled as examples. Personal offer values, official reference context, derived inputs and user assumptions remain distinguishable. Forecasts are presented as scenarios or ranges.

Review states

Each article has a verification date and review state. News has source publication, effective and validity dates. Material formula changes increment the method version.

Independence

Commercial relationships cannot change formulas, rankings, break-even points or editorial conclusions. Any future partner link must be visibly labelled.
