Calculated Industries

We build the most accurate tools in the trade. The ones you’ll find in the hands of the professionals who build our homes and communities. Founded in 1978, Calculated Industries (CI) is a global leader of specialty calculators and measuring tools for the construction industry. From our headquarters in Carson City, Nevada, we design our tools and distribute them across the U.S and internationally. CI has produced dozens of award-winning products over the years. Most recently, Builder magazine readers gave Calculated Industries the #1 Quality Rating for Builder Instruments. It is the third time we have been honored with this top rating. We remain dedicated to our handheld calculators and measuring tools. Our flagship product, the Construction Master calculator has sold over 3 million units since its launch. But in recent years, we’ve also kept up with the demand for app-based tools. And this new market has put our products on the mobile devices of construction professionals and small business owners around the world.
