Concrete Volume Calculator
Estimate concrete quantity for any rectangular pour — slabs, footings, beams or walls. Enter length, width and thickness, add a waste allowance, and read off volume in m³ / yd³ plus estimated weight.

CALCULATION
METHOD
Uses the volumetric method:
V = L × W × T; quantity including waste Vtotal = V × (1 + waste%); weight W = Vtotal × ρ.- Volumetric method: volume = cross-sectional area × thickness, the standard basis for concrete quantity take-off.
- Waste allowance and density are empirical values; verify them against the project specification and the approved mix design.
