How to calculate concrete footing volume
This calculator finds the volume of a rectangular concrete footing from its length, width, and depth.
How the calculation works
Volume = Length × Width × Depth, converted to cubic yards by dividing the cubic-foot result by 27.
Example
A footing 20 ft long, 2 ft wide, 1 ft deep: Volume = 20 × 2 × 1 = 40 cubic feet, or 40 ÷ 27 ≈ 1.48 cubic yards.
Frequently asked questions
How is Result calculated?
Result = [Footing cross-section] × [Total length] ÷ 27.

Pro Tips for Concrete Footing Volume
- Confirm footing depth requirements with your structural plans or local code before finalizing dimensions — depth is often the dimension most likely to be under-measured.
- Add a waste allowance (5-10%) for uneven excavation and minor form leakage.
Common Concrete Footing Volume Mistakes to Avoid
- Using the trench width instead of the actual footing width if they differ, which would misstate volume.
