How to Calculate

Beam Concrete Formula

Volume = Width × Depth × Length

Multiply the beam width, depth, and length (all in metres) to get the volume in cubic metres. For multiple beams, multiply the single beam volume by the quantity. Add 5–10% waste for formwork tolerances.

Standard beam

230mm × 450mm × 5m = 0.5175 m³

Lintel beam

150mm × 200mm × 2m = 0.06 m³

Multiple beams

Sum individual beam volumes for total concrete.
