About TradeCalc
What is TradeCalc?
TradeCalc is a network of trade-specific calculator websites built for construction professionals. Unlike general calculator sites that try to serve everyone, TradeCalc focuses on deep verticals. We cover electricians, HVAC technicians, plumbers, and roofers — each vertical with a full suite of code-referenced calculators.
Why Trade-Specific Calculators?
Tradespeople don't need a generic percentage calculator or a BMI tool. They need voltage drop calculators that reference NEC tables and duct sizing tools that follow ASHRAE standards. General calculator sites offer a handful of construction tools. We build dozens per trade — each with a how-to guide and code references.
Our Mission
Make every calculation on the job site fast, accurate, and free. No app downloads, no subscriptions, no paywalls. Open your phone, pick your trade, and get the answer you need in seconds.
Built for the Job Site
Every calculator on TradeCalc is designed mobile-first. Big buttons, clear inputs, instant results. We know you're using this on a phone with gloves on, not at a desk with a keyboard. That's why we keep things simple and fast.
