About YourCalc

What Is YourCalc?

A free library of 100+ professional-grade calculators spanning finance, health, engineering, law, gaming, audio, and more. Built for accuracy. Built to last.

YourCalc is a product of KnotStranded LLC, an independent software and digital product studio based in Camarillo, California. KnotStranded builds practical tools for real people — no VC funding, no growth hacks, just useful software.

Why We Built It

Most calculator sites are outdated or untrustworthy. We use cited, verified formulas: IRS brackets for tax tools, WHO standards for health metrics, Cockcroft-Gault for clinical dosing, verified engineering standards. Every formula is sourced and tested.

Who Uses YourCalc

We serve a broad audience from financial professionals running quick scenarios to small business owners calculating payroll and tax implications. Students verify homework, engineers validate load calculations, and medical professionals screen patients. If you need an accurate calculation done right, YourCalc is here for you.

Our Philosophy

Transparent formulas. Client-side only. Permanent free access. Mobile-first. No accounts. No data collection. No paywalls.
