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) × 1.55.
Truckloads = cubic yards (with waste) ÷ truck capacity.
Total cost = cubic yards (with waste) × price per cubic yard + delivery.
Material assumptions
- Road base density: about 1.55 tons per cubic yard.
- Standard driveway depth: 6 inches compacted.
- Class-2 base compacts 20–25% from loose volume.
