Editorial Policy

Quantus publishes calculators and explanatory analysis. Both are held to the same standard: show the arithmetic, state the assumptions, and say where the model stops being reliable.

• No result, ranking or recommendation is influenced by a commercial arrangement.
• No calculator output is withheld, delayed or degraded to collect contact details.
• Every quantitative claim on the site is either produced by a tested calculation module or attributed to a named source.
• Uncertainty is stated as uncertainty. Where a figure depends on an assumption, the assumption is exposed as an input.
• Structured data describes only what is visible on the page. No review, rating or claim is marked up that a reader cannot see.

Calculator content is written alongside the calculation module it documents. The formula shown on a page is the formula the module implements, and the worked example is generated by running the tool rather than typed from memory.

Articles are written to explain a specific piece of mathematics with a distinct purpose. Where two pieces would cover the same ground, they are merged rather than published as near-duplicates. No article is written to occupy a keyword it does not genuinely address.

Content is original. Quantus does not copy structure, wording, layout or examples from other calculator sites, and does not paraphrase competitor copy as a substitute for explaining a concept properly.

Melissa Roiatti is the editor of Quantus Tools & Intelligence and the named author of the calculator documentation and the written analysis on this site. Pages carry that attribution visibly, not only in their structured data.

Ugo Candido, MBA, reviews that content before a page is dated as reviewed, checking that the rules, definitions and limitations a page asserts match the sources it cites.

A page shows the date its review was actually carried out. That date is written by hand rather than taken from the build clock, and it is kept separate from the page's updated date: confirming that a page is still correct is a different claim from changing it.

Every calculator must pass its automated tests before it can ship: a known mathematical case, a zero-rate case, a single-period case, an invalid-input case, a boundary case and a rounding check.

Every page must also pass two content gates. The internal-link validator checks that contextual links resolve to real pages and meet the site's linking rules. The content validator checks that each calculator page carries a unique title, a primary keyword, a quantitative table, a methodology section, a worked example, stated assumptions and limitations.

A page that fails either gate does not publish. Both checks run from the command line and both are part of the build routine.

Errors are treated as defects rather than as editorial disagreements. A wrong calculation is fixed in the module, and a test that fails without the fix is added so it cannot regress.

When a figure changes, every page quoting it is updated in the same change. Worked examples are regenerated rather than adjusted by hand, so a page's prose and its calculator cannot drift apart.

If you find a number that does not reproduce, write to editorial@quantus.tool with the inputs you used.

Each page carries an updated date in the site registry, and the sitemap reports that date rather than the date of the most recent build. A rebuild does not claim that content changed.

Pages are revisited when the underlying calculation changes, when a cited source publishes new data, or when a rule the calculator describes is amended.

Commercial placements are configured in a file that no calculation module imports. It is structurally impossible for a placement to alter a result, an ordering or a recommendation, because the calculation layer has no access to it.

Placements may only appear after a result and its interpretation, never before, and never in a position that interrupts reading a number. Any partner must be named and the relationship disclosed at the point of the placement.

The affiliate disclosure page sets out the current position in full.

Quantus publishes general educational content. It is not investment, tax, legal or insurance advice, and it does not account for personal circumstances.

Calculators that touch tax or insurance carry a contextual disclaimer stating that plainly, because those are the areas where a general model is most likely to be mistaken for personal guidance.
