How it's calculated

Area is derived from your shape inputs and converted to sq ft.

Depth is converted to feet; cubic feet = area × depth.

Cubic yards = cubic feet ÷ 27, then × (1 + waste %) × (1 + compaction %).

Estimated tons = cubic yards (with waste) × 2.

Truckloads = cubic yards (with waste) ÷ truck capacity.

Total cost = cubic yards (with waste) × price per cubic yard + delivery.

Material assumptions

  • Concrete density: 2.0 tons per cubic yard.
  • Footing depth must extend below the local frost line.
  • Include a 10% waste factor for spillage and over-excavation.
