📐 Formula
💡 Practical Example
50 ft long × 12 ft wide driveway with 4 inches of #57 Crushed Stone and 10% waste factor: Gross Volume = × 1.10 = 8.15 cu yds. Total Weight = 8.15 × 1.40 = 11.41 tons (22,820 lbs -- 1 dump truckload).
📖 About Driveway Gravel & Crushed Stone Volume & Tonnage Calculator
Driveway gravel estimation requires factoring in subgrade settlement and compaction loss (typically 10% extra). Standard residential gravel driveways require 4 to 6 inches of total aggregate depth.
To use the Driveway Gravel & Crushed Stone Volume & Tonnage Calculator, enter your Driveway Length, Driveway Width, Desired Gravel Layer Depth and other values. The calculator instantly computes Volume in Cubic Yards, Total Weight in Tons and more. Results update in real time as you change any input — no submit button needed.
How to Use This Calculator
Enter your Driveway Length (e.g. 50 in ft), Driveway Width (e.g. 12 in ft), Desired Gravel Layer Depth (e.g. 4.0 in inches), Gravel / Aggregate Type Density — choose from #57 Crushed Stone (1.40 tons/cu yd -- Standard Base & Surface), Pea Gravel (1.35 tons/cu yd -- Decorative Top Coat), Crusher Run / Dense Grade (1.50 tons/cu yd -- Heavy Compacted Base), and Compaction & Waste Safety Factor (e.g. 10 in %). Measure twice before entering dimensions — small measurement errors scale up significantly in material estimates.
The Formula
Cubic Yards = (Length ft × Width ft × Depth ft) ÷ 27
Gross Volume (cu yds) = Cubic Yards × (1 + Waste Factor %)
Total Weight (tons) = Gross Volume (cu yds) × Material Density (tons/cu yd)
Dump Truckloads = Ceil[ Total Weight (tons) ÷ 12 tons per truckload ]
Worked Example
50 ft long × 12 ft wide driveway with 4 inches of #57 Crushed Stone and 10% waste factor:
Gross Volume = 1.10 = 8.15 cu yds.
Total Weight = 8.15 × 1.40 = 11.41 tons (22,820 lbs -- 1 dump truckload).
Understanding Your Result
Construction estimates are starting points — site conditions, material specifications, and local code requirements will affect final quantities and costs. Always obtain at least three contractor bids for major projects. Local building departments can confirm permit requirements and inspection milestones. Add waste factors appropriate to the material type and complexity: 10% for simple rectangular shapes, 15–20% for complex geometries or custom cuts.
