What is footing depth?
Enter the vertical thickness of the concrete pad from the bottom of the footing to the top surface.
Footing Concrete Calculator
Calculate concrete volume for isolated footings by length, width, depth, and quantity.
Footing Concrete Calculator Formula
- Footing Volume
Length × Width × Depth - Total Volume
Single footing volume × Quantity - Wastage Allowance
Total volume × (1 + Wastage ÷ 100) - Supporting Metrics
Convert m³ to ft³ for ordering
Assumptions
- Footings are modelled as rectangular prisms with uniform depth.
- Pedestal, column stub, and reinforcement volume are excluded.
- Wastage covers over-excavation, spillage, and uneven base.
Frequently Asked Questions
How much wastage should I add for footings?
5–10% is typical. Irregular excavation or stepped footings may need more.
Can I calculate strip footings?
For continuous strip footings, use length as the run and width as the strip width.
