Editorial Policy

Who writes the content

Calculator documentation, guides and examples are written and maintained by the Finance Calculator X editorial team — in practice, the site's operator (see About) supported by systematic verification tooling. We use transparent organizational attribution rather than invented personas: you will never see a fabricated expert, a stock-photo "advisor", fake credentials, or testimonials on this site. If independent professional reviewers join the project, their real names and verifiable qualifications will appear on the pages they review.

Standards every page must meet

• Computed, not estimated. Every numeric example is produced by the same tested calculation library that powers the calculators — never typed from memory. If a page says a loan costs $4,045.54 in interest, that number came out of the engine.
• Specific to its subject. Each calculator's explanation, worked example, FAQ and limitations are written for that calculator. We do not publish near-duplicate pages targeting keyword variations.
• Assumptions visible. Any simplification, convention or rule of thumb is stated on the page where it's used.
• Plain language. Jargon is defined at first use; formulas are explained in words alongside the notation.
• Dated and versioned. Pages display a last-reviewed date and formula version, updated whenever anything material changes.

Advertising independence

The site may display advertising (such as Google AdSense) to fund its operation. Advertising never influences formulas, defaults, results, rankings or editorial content — and ads are visually distinct from calculator functionality and content. We do not currently publish sponsored content or affiliate recommendations; if that ever changes, such content will be clearly labeled.

Because money is a YMYL topic

Financial content can affect people's wellbeing, so we hold it to a higher bar: no guaranteed-outcome claims, no predictions dressed as facts, no product recommendations, no urgency tactics, and explicit boundaries between mathematical results, educational context and anything resembling advice (which we don't provide — see the disclaimer). Where rules differ by country — tax treatment, prepayment rights, deposit insurance — we say so rather than assuming one jurisdiction.

Mistakes

When we get something wrong, we fix it and say so. The corrections policy describes the process, and the contact page is the fastest way to report an issue.
