Editorial & quality policy

Who publishes kalkuleyt

kalkuleyt is an owner-operated calculator website. There are no invented authors, staff pages, credentials or endorsements, and no article is attributed to a person who does not exist.

How calculators and pages are built

Calculators are built from documented standard formulas or named data sources. The supporting text is written for the specific task: what the tool calculates, how to use it, the formula, a worked example, how to read the result, and the limits. Text is not scraped, copied from competitors or spun from other pages on this site.

How quality is checked

Calculation logic is covered by automated tests, including edge cases such as zero rates and invalid inputs. Pages state their assumptions and limitations, and every calculator page shows its method and sources in the Methodology & data section.

Automated tests are automated tests. The site does not claim medical review, financial review or expert review that has not taken place.

Advertising

The site is funded by display advertising. Ads are placed around the content and are never inserted inside calculator inputs, results or buttons, and they do not influence any result. Commercial or affiliate links, when present, are labelled.

Updates

Pages are updated when a formula, source or explanation changes. The site does not display fabricated publication or “last reviewed” dates. When dynamic data is shown, the source and its date are displayed with the result.

Scope

kalkuleyt provides general information and estimation tools. It is not a law, tax, accounting, medical or financial advisory service.
