Concrete Footing Calculator
For pad (isolated) footings: enter the dimensions of one footing together with the number of footings, and the total pour quantity is summed directly.

METHOD
Volume per footing
V₁ = L × W × D; total quantity V = V₁ × n.- 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.
