CalculatorCorp is a library of practical, transparent calculators across finance, maths, science, construction, and health & fitness. There are 20 categories of various calculators available, with a total of 5000+ of them.
Who runs this site?
Dan Dadović — Founder & Editor
I run CalculatorCorp day-to-day: writing specs for each tool (formulas, units, rounding, edge cases), shipping product updates, and keeping the “How it works” notes and change logs honest.
Before this, I spent years at Ezoic (Commercial Director since 2022; at Ezoic since 2017) building and leading top-performing business development teams and helping standardise publishing operations. Earlier I worked at the University of Zagreb’s FOI, where I developed close ties with academics—many now review our more sensitive (YMYL) topics.
Website is owned by Ivana Pintar.
Ivan Todorović — Infrastructure & Production
Ivan looks after how things run: build/deploy, versioning and rollbacks, uptime monitoring, performance hygiene, and regression tests. His makerspace background (3D printing/scanning, CNC, lasers) is handy for testing geometry and measurement tools and keeping our setup practical and robust.
How CalculatorCorp is different
- We show our work. Every calculator documents its formulas, units, assumptions, and limitations—in plain English.
- We validate outputs. We compare results to official tables/standards or peer-reviewed sources and keep small edge-case checks.
- We keep receipts. Each page has a change log under the byline for any substantive update.
- Experts review YMYL topics. Health/fitness, finance, chemistry/biology, construction, and electrical power tools carry a clear “Reviewed by” line with name and credential.

What’s on the site
5,000+ calculators (as of October 2025) across Biology, Chemistry, Construction, Finance, Food, Games, Health & Fitness, Maths, Physics, Science, Sports, Time, Tools & Converters, and Unit Conversion.
Use of AI
We use AI to help 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. Full details: Editorial & Methodology → Use of AI.
