Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net wall face = length × height × sections − openings. Volume = net face × wall thickness, followed by the entered allowance.

FAQ
Concrete Retaining Wall Volume Calculator questions
Does this include the retaining-wall footing?+
No. Estimate the footing separately with the wall-footing calculator.
Should both wall faces be counted for concrete?+
No. Concrete volume uses one face area times thickness; two faces are shown only as a formwork guide.
Can this design a retaining wall?+
No. Structural and geotechnical design are outside this material calculation.
