Who operates the site
Calc for Trades is an independently operated website. Calculator logic, worked examples and field guides are maintained by the Calc for Trades Editorial Team. We publish our process openly and do not claim professional credentials that the site does not have.
Built around real tasks
Each calculator starts with familiar US units, sensible defaults and a result that can support an estimate or planning conversation. No account or email is required. Supporting blog field guides explain how to measure, document assumptions and recognize when the calculator is not enough.
Private by design
Calculator inputs are processed in the browser. The current product does not send project measurements to a Calc for Trades database.
Clear about limits
Calc for Trades is a fast reference, not a substitute for plans, permits, current codes, manufacturer instructions or a licensed professional. Safety-sensitive tools state their assumptions and verification requirements.
How content is reviewed
Formulas, default results and worked examples are checked before publication. Material changes receive a new review date, and readers can report possible errors through the Contact page. The full process appears in our Editorial & Review Policy.
Product direction
The initial collection covers measurement, stairs, roofing, concrete and electrical voltage-drop calculations. New tools and guides will be added only when they solve a clear jobsite problem without making the experience harder to use.
