Construction quantities. Made simple.

Every material calculator will tell you a volume. MaterialQuant tells you what to order — waste included, rounded to a quantity your supplier can batch, with the bag counts, truckloads and cost worked out.

Calculators

Concrete Calculator — Slabs, footings, walls, columns, stairs, post holes and more. Add several pours to one project and get a single consolidated order.
Gravel Calculator — Multiple areas, multiple material layers. Works back from the finished compacted depth to the loose tonnage to order, with sourced density ranges.
Landscaping Calculator — Mulch, topsoil, grass seed and sod from one set of measured beds and lawns. Measure an area once and every material reads it.
Hardscaping Calculator — Pavers with their base and sand, retaining-wall block and caps, and pool shell, finish and coping — from one set of measured areas, wall runs and pools.
Interior Calculator — Paint, drywall and wallpaper from shared rooms and openings. Plan containers, sheets, finishing supplies and patterned wallpaper rolls.
Cubic Yard Calculator — Any shape, any units, straight to cubic yards. The fast one — for when you know the measurements and just need the volume.

Straight to one material

Each of these opens the same workspace with one material already selected — useful when you know exactly what you are buying:

What makes these different

One project, many pours. A driveway, its footings and a run of post holes come off the same truck, so they should be one order — not three separate calculations you add up yourself.
Waste is applied, not merely advised. Most calculators print "add 10%" next to a number that does not include it.
Order quantities, not just volumes. Rounded up to what the plant can actually batch, and a possible short-load charge flagged before it surprises you.
Ranges where reality is a range. Material density varies. We show the band and name the source rather than inventing a third decimal place.
Results that leave the page. Copy the order sheet, print it, or share a link that reopens with every figure intact.

How the numbers are derived

Bag yields come from manufacturers' technical data sheets, densities from recognised engineering conventions, delivery practice from NRMCA. Other calculator sites are used to cross-check our arithmetic and never as a source. Every constant, with its citation and its uncertainty, is listed on the methodology page.
