Concrete Wall Footing Calculator

Estimate concrete for a continuous wall footing or strip footing. Calculate footing volume, bags, material cost, gravel base, wall projection, and a simple soil bearing check.

Wall footing
Used in the saved report.
Controls result display.
Use 1 for one continuous wall line. Enter at least 1 run.
Length along the wall line. Enter a length greater than 0.
Total bottom width of the strip footing. Enter a width greater than 0.
Concrete thickness of the footing. Enter a depth greater than 0.
Used for projection per side. Enter a wall thickness greater than 0.
Use 0 if no gravel base is needed. Gravel depth cannot be negative.
Use 5–15% for most pours. Waste cannot be negative.
Usually use volume with waste.
Optional material-only estimate. Cost cannot be negative.
For a simple soil bearing check. Load cannot be negative.
Used only when wall load is entered. Enter a soil value greater than 0.

Formula used
Footing volume = Length × Width × Depth × Runs

All dimensions are converted to feet before concrete volume is calculated.
