Concrete, asphalt and masonry calculators

Concrete and masonry calculators for what is poured, laid and paved: the cubic yards, bags, blocks or tons to order for the sizes on your plans.

Concrete calculatorCubic yards of concrete for slabs, footings, columns, steps and post holes.
Asphalt calculatorTons of hot-mix asphalt for a driveway, a path or a patch, from area and thickness.
Concrete block calculatorConcrete blocks, courses and bags of mortar for a wall, drawn in running bond.
Concrete bag calculatorBags of concrete mix, 40, 60 or 80 lb, for a slab, steps or post holes.

Sizes from your plans, quantities from us

Concrete is ordered by the cubic yard or bought by the bag, block by the piece, mortar by the bag and asphalt by the ton. Each calculator starts from the sizes you measured or the ones on your plans, adds the pieces up before it rounds, and answers in the unit you will be quoted in.

None of them chooses a thickness, a footing, a reinforcement or a mix: those come from your plans, your building department or an engineer.
