How to use the Concrete Foundation Calculator
Select the foundation type first. Then enter the length, width, thickness, height, depth, or pier count for that foundation. The tool converts all units, adds waste, estimates bags, and shows the cost when a price is entered.
Foundation types covered
- Slab foundation
- Strip or continuous footing
- Concrete foundation wall
- Pier foundation
- Concrete block foundation with optional core fill
Concrete foundation cost estimate
The cost result uses the order quantity with waste multiplied by your concrete price per cubic yard. It is a material estimate only. Labor, excavation, formwork, rebar, gravel, pump fees, and local delivery charges can change the final cost.
Important note
This calculator is for estimating concrete volume and material cost. It is not a structural design tool. Confirm foundation size, footing depth, rebar, soil conditions, frost depth, and code needs with a qualified contractor or engineer.
