What Calculated Industries does

Calculated Industries, founded in 1978 and headquartered in Carson City, Nevada, is a privately held manufacturer and marketer of specialty construction calculators, precision measuring tools, and trade-specific mobile applications. The company serves construction professionals (contractors, estimators, framers, carpenters), specialized trades (electricians, plumbers, concrete/HVAC/machinist workers), real estate professionals, and DIY consumers. Its portfolio spans 35+ branded product lines including the flagship Construction Master Pro calculator family, ElectriCalc Pro, Pipe Trades Pro, HeavyCalc Pro, ConcreteCalc Pro, Machinist Calc Pro 2, Qualifier Plus/Real Estate Master (real estate finance), AirShim inflatable pry bars, Blind Mark magnetic drywall locators, AccuMASTER angle/moisture instruments, and DigiRoller Plus III measuring wheels, plus 44+ mobile apps across iOS and Android that mirror the handheld lineup.

The underlying technology rests on proprietary feet-inch-fraction and dimensional-math algorithms developed over four decades, paired with patent-pending mechanical innovations such as the AirShim Pro STEEL steel-plate design and rare-earth magnet-based drywall location systems. In May 2026 the company launched Ask CMPro, a generative-AI assistant integrated into the CMPro app that provides voice- and text-based step-by-step construction-math guidance grounded in the firm's proprietary CMPro corpus and developed by an in-house Carson City engineering team.

Revenue mechanics are dominated by one-time hardware sales (handheld calculators and measuring tools typically priced $25-$100, e.g., Construction Master Pro at $74.95 MSRP, AirShim Pro STEEL at $24.95) supplemented by mobile app one-time purchases and a smaller accessories and parts stream. Go-to-market is product-led and multi-channel: direct e-commerce via calculated.com, national retail through Home Depot, Amazon, Staples, and Menards, plus a U.S. dealer referral and international reseller network. Marketing relies on a YouTube tutorial library, owned social channels (Twitter/X, Facebook, Instagram), live chat and knowledge-base support, and the "Tool Insights Crew" newsletter.

Broad incumbents

• Leica Geosystems: Leica Geosystems produces high-end surveying and measurement instruments (laser distance meters, total stations, laser levels). Comparable to Calculated Industries in digital measuring and layout tools for construction professionals, but at the premium/precision end of the market.
• Milwaukee Tool: Milwaukee Tool is a major power and hand tool brand owned by Techtronic Industries, focused on professional contractors and trades. Comparable to Calculated Industries in targeting the same contractor end customer and adjacent jobsite tool categories.
• Klein Tools: Klein Tools is a leading manufacturer of hand tools for electricians and trades professionals. Comparable to Calculated Industries in serving specialized trades (e.g., ElectriCalc Pro alongside Klein's electrical tools) with a focus on professional-grade durability.
• Casio: Casio is a large incumbent in calculators (scientific, graphing, and specialty) and also sells watches and other electronics. It overlaps with Calculated Industries in the specialty/construction calculator category, though construction is a small slice of Casio's overall portfolio.
• Hilti: Hilti manufactures power tools, fastening systems, and jobsite software/services for construction professionals. Comparable to Calculated Industries in serving professional contractors with productivity-oriented tools and in exploring software/digital workflow layers on top of hardware.
• Stanley Black & Decker: Stanley Black & Decker owns Stanley, DeWalt, Craftsman, and Irwin, covering hand tools, measuring, and layout tools used by contractors. It is comparable to Calculated Industries' measuring and layout tools (DigiRoller, Blind Mark, AccuMASTER) but as part of a much larger portfolio.
• Fluke Corporation: Fluke is a leader in electronic test and measurement instruments (multimeters, clamp meters, thermal imagers) for electrical and industrial professionals. Comparable to Calculated Industries in jobsite measurement instrumentation and in serving electrical contractors.
• Hewlett-Packard (HP): HP is a broad incumbent with calculator products and a large professional/enterprise footprint. It is comparable to Calculated Industries in specialty computing devices but serves a much wider product portfolio beyond construction.
• Bosch (Robert Bosch): Bosch manufactures power tools, measuring tools, and accessories for construction professionals under its professional line. Comparable to Calculated Industries in laser distance measurement (e.g., Laser Dimension Master 130), digital angle/leveling tools, and jobsite workflow tools.
• Texas Instruments: Texas Instruments is a dominant calculator manufacturer (scientific and graphing) with a strong education and professional channel. It is comparable to Calculated Industries in specialty calculator hardware but focuses on academic and scientific rather than construction-specific use cases.
