Concrete Footing Calculator
Calculate concrete volume for a strip footing using total length, width, and depth.
Project
Formula
How the result is calculated
Footing volume = total length × width × depth.
Worked example
Check the order logic
Combine separate footing runs as individual sections when their dimensions differ. The final order quantity totals them once.
Assumptions
Waste and supplier rounding stay editable
The launch defaults are 10% waste and upward rounding to 0.25 yd³ or 0.10 m³. Open “Adjust assumptions and costs” to use your supplier’s increment, actual prices, density, truck capacity, or product bag yield.
