A concrete calculator works out how much concrete a slab, footing or path needs, and how many bags of pre-mix that is. It multiplies length × width × thickness to get the volume — in cubic yards or cubic metres — using consistent units (feet with inch thickness in imperial, metres with centimetre thickness in metric). Set a quantity to size several identical pours at once, add a waste allowance for spillage and over-excavation, choose the bag size, and enter a price per bag for a cost estimate.
Worked example: a 10 × 10 ft slab, 4 inches thick, is 10 × 10 × (4 ÷ 12) = 33.3 cubic feet, about 1.23 cubic yards. Since an 80 lb bag yields roughly 0.6 cubic feet, that is 33.3 ÷ 0.6 ≈ 56 bags — a lot of mixing, which is why ordering ready-mix by the yard is usually cheaper past about a third of a yard.
Use it before pouring a patio, shed base, fence-post footing or path so you order the right amount and neither run short mid-pour nor pay for wasted concrete.

Ndezvipi zvinhu zvakasiyana zvandinofanira kushandisa kuti ndiite imba?
A 10 × 10 ft slab, 4 mu thick is 10 × 10 × (4 ÷ 12) = 33.3 cubic feet, which is about 1.23 cubic yards.
Mabhegi mangani ekongiri ezuva nezuva ezuva?
An 80 lb bag yields roughly 0.6 cubic feet, so a cubic yard (27 cu ft) takes about 45 bags. Ordering ready-mix by the yard is usually cheaper once you pass a third of a cubic yard.
Ndinofanira kuisa extra for waste?
Yeah — a 5-10% chikwereti chinotaura kusvibiswa, zvakasiyana sub-base uye pamusoro-kuchera kuti iwe hauna kutamba pfupi pakati-kupisa. Set it under advanced options and the volume, bags and cost all include it.
Ndezvipi zvipfuyo zvekongiriti zvinoita kuti zvive nekubhururuka kwekubhururuka?
Izvi zvinoenderana nebag size: a cubic yard i 27 cubic feet, saka pa 0.6 cu ft pa 80 lb bag zvinotora pamusoro 45 mabhegi, pa 0.45 cu ft pa 60 lb bag pamusoro 60, uye pa 0.30 cu ft pa 40 lb bag pamusoro 90. The calculator uses the bag size you select.
Kana ndichifanira kukumbira ready-mix sezvandinoda zvivharo?
Mabhegi anokwana makambani madiki kusvika kumazana maviri emamita emamita; kunze kweizvozvo, kusvibiswa kwebasa uye mutengo wechikwata unokwira nekukurumidza, uye chitima chekugadzirira-kutambanudza chinopihwa nechitima chekufambisa chine mutengo wakaderera uye chine basa rakawanda. Vazhinji vatengesi vane huwandu hwakanyanya hwekutakura hwemamita makumi maviri nemaviri emamita emamita.
Ndezvipi zvidimbu zvinokosha kuti zvive nekongiri?
Four inches is standard for patios, walkways and shed bases; driveways and areas taking vehicles are usually 5–6 inches, often with reinforcement. Enter the thickness your project needs — it directly scales the volume and bag count.
