Tradie Construction Calculator
How much concrete and timber
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Sixteen calculators, metric or imperial, no permissions and no sign-in. Concrete, brick, tile, paint, timber, rebar, roof and stairs, with a 3-day free trial on Pro.
On site with a construction calculator instead of a notepad and a guess. Measure where you stand, type it in, and this construction calculator turns it into what you order: cubic metres of concrete, bricks, sheets, litres of paint, bar weight. Sixteen calculators, all metric.
CONCRETE, FOOTINGS AND FILL
The concrete calculator does slabs, columns and cylinders, returns the volume, then splits it into cement, sand and aggregate with a bag count for the mix you pick (1:2:4, 1:1.5:3, 1:3:6). Strip and pad footings get a screen, and the gravel screen turns fill volume into weight.
BRICK, TILE AND PAINT
The brick calculator works from wall length and height, brick size, mortar joint and wastage, and gives brick count plus mortar volume. The tile calculator does floors and splashbacks with grout gap and waste. The paint calculator takes several walls at once, deducts doors and windows, applies coats and coverage, and returns litres.
ROOF, TIMBER AND STEEL
The roofing calculator gives roof area, pitch angle and rafter length for gable and hip roofs. The timber calculator turns thickness, width, length and quantity into board feet and total volume with wastage - what you want when pricing a pack. The rebar calculator sets out one-way or two-way mats. As a carpentry calculator it does stairs too.
BEFORE THE POUR, BEFORE THE HARDWARE RUN
On a slab just set out, a builder calculator in your pocket beats a guess: measure, tap, and the volume is there before the truck is booked. On the way to the trade counter it is a construction materials calculator, so the order is written before you walk in. Estimating at the kitchen table, the cost estimate screen prices a material result from a unit rate you enter.
WHY THIS ONE AND NOT ANOTHER BUILDING CALCULATOR
Most results here do one thing: a concrete calculator, or a tile calculator, nothing else. This is a roofing calculator, a carpentry calculator and a masonry tool in one app, one unit setting, one history. As a builder calculator it stays out of the way: no account, no sign-in, and it opens with no signal. Six are free forever - concrete, area, volume, brick, unit converter and feet and inches - so a building calculator this plain beats a spreadsheet. Pro adds the other ten plus cost estimate, 3-day free trial.
