Overview
BuildCalc is a free, mobile-friendly construction calculator website that solves instant jobsite math for contractors, builders, and DIYers. No app install, no login required—just load it in a browser and get answers. The site includes interactive calculators organized by trade: excavation, concrete, framing, electrical, roofing, plumbing, rebar, trim carpentry, and unit conversions. All calculations happen client-side in the browser, so results are instant and work offline. A buyer cloning this business can customize calculator precision, add trade-specific tools, or white-label it for their own contracting brand.
