Who we are
CalculatorCorp Editorial Team maintains a large library of practical calculators across finance, maths, science, construction, and health & fitness. The site is developed and edited by Dan Dadović, with help on infrastructure from Ivan Todorović and formal reviews by independent subject-matter experts.
For topics that can affect health or finances (YMYL), we show a clear Reviewed by line with the expert’s name and credential. Meet them here: /reviewers/
Team & roles
Dan Dadović — Founder & Editor
- Digital publishing — Commercial Director at Ezoic (since 2022; at Ezoic since 2017). Built and led top-performing business development teams and helped set up office-level best practices for sustainable growth.
- Calculator methodology — Writes specs for every tool (formulas, units, rounding, edge cases). Keeps “How it works” sections honest and the change log tidy.
- Process & automation — Builds WordPress MU-plugins and WP-CLI jobs for schema, internal linking, sitemaps, and QA checks so pages stay fast and consistent.
- Academic collaboration — Previously at the University of Zagreb’s FOI (2013–2017) working closely with industry. Now coordinates FOI experts as independent reviewers on YMYL topics.
Ivan Todorović — Infrastructure & Production (Makerspace Varaždin)
- Reliability — Handles build/deploy, versioning and rollbacks, uptime monitoring, and page-speed hygiene for our self-contained HTML/JS calculators.
- Quality checks — Runs regression tests across calculator bundles, checks accessibility (labels, focus, keyboard paths), and validates JSON-LD.
- Hands-on maker skills — Experience with 3D printing/scanning, CNC, and CO₂ lasers from Makerspace Varaždin informs testing for geometry/measurement tools.
- Community roles — Leadership in EduNorth, VANIMA, and CONNECT International adds structure and accountability to our production workflow.
How we build calculators
- Write the maths first. Equations, variables, units, valid ranges, rounding rules.
- Build & test. Self-contained components with input validation and keyboard-friendly UX.
- Validate outputs. Compare against official tables/standards or published references; record a few edge-case checks.
- Explain it. Every page has a plain-English “How it works”, a worked example, and clear limitations.
- Log changes. We add a one-liner under the byline for any substantive update.
Review & fact-check
YMYL topics (finance, health & fitness, chemistry/biology, construction, electrical power) are reviewed by named experts. Their names, credentials, and links appear on the page.
What reviewers check
- Formula correctness, units, and rounding
- Boundary conditions and “gotchas”
- Sources (authority & recency) and disclaimers

Use of AI
We use AI to draft non-advisory text, refactor code, and generate test cases. Humans specify the maths, ship the code, and review outputs. YMYL pages always get a named expert review. We don’t publish medical or financial advice.
Sources & standards
We cite reputable sources: government guidance (e.g., HMRC, NHS), standards bodies (e.g., IEC, ISO, BSI), and peer-reviewed research. When rules depend on jurisdiction, we say so.
Corrections policy
See something wrong? Email [email protected]. We aim to verify within 3–5 working days and note confirmed fixes in the page’s change log.
Independence & disclosures
Reviewers act in a personal capacity. Affiliations are listed for identification only and don’t imply endorsement. If an affiliate link appears, it never affects a calculator’s maths or result.
