Construction Calculator & Cost
How much concrete, tile, paint
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
16 calculators for concrete, drywall, tile, rebar, roofing and stairs. Every result shows its formula. Six are free; Pro adds ten more, cost estimates and no ads.
A construction calculator for the jobsite, not the office. Type in the sizes you already have and this construction calculator gives you quantities you can order — 16 calculators, imperial or metric, offline.
Concrete calculator: length, width and thickness for a slab, column or cylinder, and the concrete calculator returns volume, the cement, sand and gravel split, cement bags and your mix ratio. Before the pour it works as a concrete slab calculator for driveways and pads, and as a cubic yard calculator for the order.
Footing calculator and rebar calculator cover the rest of the pour: the footing calculator sizes strip and pad foundations, and the rebar calculator turns bar size, spacing, cover and lap into bar count, total length and weight.
Drywall calculator, tile calculator and paint calculator handle the finish trades: the drywall calculator returns sheets plus joint compound and tape, the tile calculator gives tile count for your grout gap and waste, and the paint calculator turns walls, deductions and coats into cans.
Roofing calculator and stair calculator do the trigonometry: the roofing calculator handles gable and hip roofs and returns roof area, pitch angle and rafter length, and the stair calculator returns steps, riser, tread, stringer length and angle. Lumber calculator: pick 2x4 to 6x6 or type your own, and the lumber calculator returns board feet with waste.
Ordering ready-mix: the concrete slab calculator settles the size, the cubic yard calculator the order.
In the room with a tape, the square footage calculator covers rectangles, triangles, circles and trapezoids, and that square footage calculator number feeds the tile and paint screens. On a cut list, the feet and inches calculator adds, subtracts, multiplies and divides feet, inches and fractions to sixteenths, and the same feet and inches calculator converts to decimal or metric.
Quoting on the tailgate: this contractor calculator keeps up to 100 recent results in history, and the cost estimator on material results uses unit prices you type in yourself. A contractor calculator is worth carrying only if the cost estimator runs on your prices.
Used as a material estimator it answers what the counter asks — how many, not how big — and this material estimator shows the formula, the waste and the units behind every quantity, which most calculators beside it never do. A construction material calculator has to switch systems as fast as the work does, and this construction material calculator flips imperial to metric on every screen. As a building calculator it runs fully offline, and this building calculator asks for no permissions at all.

No permissions are requested: no camera, no photos, no location. The app measures nothing for you — you type the dimensions in. Results are estimates from your numbers and standard constants, so check your local code, supplier sizes and site conditions before you order or cut.
Pro unlocks the other ten, adds the cost estimator and removes ads after a 3-day free trial. Some features require a subscription.
