How to Use This Calculator

Enter footing width (ft) and footing depth (ft) from the structural engineer's foundation design.
Enter sign face area (sqft) for wind load context.
Review concrete volume (yd3), rebar (lbs), and estimated foundation cost.
Add anchor bolt cost and concrete forming materials to the foundation estimate.
Pylon foundations must be engineered for wind load -- always use a licensed engineer for structures over 20 ft.
