How this calculator works
Calculate concrete volume, wet weight and estimated cement bags for slabs, footings and general pours.
V = L × W × D; order volume = V × (1 + waste%)

Calculate concrete volume, wet weight and estimated cement bags for slabs, footings and general pours.
Calculate concrete volume, wet weight and estimated cement bags for slabs, footings and general pours.
The calculator uses the following core relationship:
Estimating note: Actual material quantities can vary with site conditions, detailing, product dimensions, installation method, and waste.
Calculate concrete volume, wet weight and estimated cement bags for slabs, footings and general pours.
The calculator uses inputs such as Length (m), Width (m), Depth (m), Waste allowance (%), and Concrete density (kg/m³). Use values from your drawings, measurements, product data, or project specifications.
Use outputs such as Concrete volume, Volume incl. waste, Concrete weight, and Cement bags for estimating and cross-checking. Before purchasing or construction, confirm the dimensions, units, waste factors, supplier packaging, and project specifications.
