Concrete & masonry calculators

3 free calculators · instant · nothing you enter is uploaded

Concrete and mortar are mixed to a volume, poured once and cannot be adjusted afterwards, which is why a slab or a post hole is worth calculating rather than guessing. These calculators take the shape and dimensions of a pour and return the volume in cubic feet, cubic yards and the number of bags of a given mix, so you can decide between bags and a delivered load. Brick and block counts work the same way, from wall area, unit size and the mortar joint.
