How it's calculated
No black boxes — here is the exact math behind your estimate, so you can check it or adapt it for your own quote.
- 1
Cubic yards = (length × width × depth ÷ 12) ÷ 27 - 2
Tons = cubic yards × 1.4 (crushed stone density) - 3
Cost = tons × price per ton
Worked example
A 20 ft × 10 ft path at 3 inches deep.
