Calculate Volume
Typical: 5-15%
How it Works
Volume = Area × Depth. We calculate volume in ft³ or m³, apply an optional waste factor, and convert to cubic yards or cubic meters. If you provide a soil density, we also estimate metric tonnes.
Example
Area 10×10 ft (100 ft²), Depth 0.5 ft:
- Volume = 100 × 0.5 = 50 ft³
- Adjusted (5% waste) = 52.5 ft³
- = 1.95 cu yd

Tips & Notes
- Add a waste factor (5–15%) to account for compaction and spillage.
- Soil density varies; use a local supplier's value for accurate tonnage estimates.
- Use the preset buttons for common project sizes.
