Construction Calc for Mac

All-in-one jobsite calculator

Construction Calc is a versatile calculator built for people who work with building measurements every day — from builders and architects to tradespeople and contractors — and other specialists who need precise, job-related math. It’s also available as a fully functional, free option for anyone who wants a dependable calculator app.

Arithmetic and measurement capabilities

• Multiply, divide, add and subtract with standard calculator functions
• Work directly in feet, fractional inches and plain inches for fast, accurate measurement math
• Use it as a regular calculator whenever you need straightforward arithmetic, not just construction-specific calculations

Accuracy, fraction reduction, and memory controls

Construction Calc automatically rounds answers to the precision you choose and reduces fractional values to their lowest terms for clean results. The built-in memory tools let you store and manage intermediate values easily.

• Recall saved values, set a new memory value, add to memory, clear memory and subtract from memory
• Automatic rounding to user-selected precision for consistent outputs
• Fraction simplification so measurements display in standard, reduced form

Estimate materials and speed up takeoffs

Save time and money by using the app to quickly estimate quantities and dimensions for common building tasks. It’s useful for calculating areas, lengths and counts for a wide range of materials and components.

• Drywall, crown moulding, concrete, asphalt, drop-ceiling panels and balusters
• Instant calculations for areas, linear footage, quantities and simple angles
• Faster takeoffs mean fewer trips to suppliers and less waste on the jobsite

Portable, simple, and ready to use

Because it runs on your phone, you can leave bulky calculators behind and carry all the functions in one device. The interface is straightforward: enter numbers and get precise answers immediately, with no lengthy manuals or complex setup required.
