14 accurate jobsite calculators for concrete, stairs, lumber, roofing and more.
Construction Calculator gives contractors, builders, carpenters, estimators and serious DIY users fast jobsite estimates that show their work. Choose from 14 focused calculators: • Feet, inches, fractions and metric conversion • Stair risers, treads and stringer length • Stud and joist spacing • Square and diagonal layout • Rafters and ridge length • Concrete volume and bag quantities • Board feet and lumber • Rebar grids • Brick, block and mortar • Roofing materials • Drywall and room estimates • Tile and flooring • Paint coverage • Gravel, soil and excavation Built for the jobsite: • Works offline with no account required • Imperial and metric units • Formula, steps and assumptions shown with every result • Favorites for frequent calculations • Recent calculation history stored on your device • Local project folders for organizing estimates • Phone and tablet layouts • Native sharing for results • Light, dark and high-contrast themes Fair monetization: Core calculators remain useful for free. The free version uses one small banner away from calculator inputs and results—never video, interstitial or full-screen ads. An optional one-time Lifetime Pro purchase removes all ads forever. There is no subscription. Privacy by design: Measurements, prices, project names and results remain on your device. No custom backend or account is required. Construction Calculator provides planning estimates only. Confirm quantities, supplier yields, structural requirements, engineering decisions and local building codes before construction.
