What is a Crushed Stone Calculator?
A crushed stone calculator is a free construction tool that helps you determine the exact amount of crushed stone needed for various projects including driveways, drainage systems, base materials, and landscaping. It calculates volume, weight, and material costs for accurate project planning.
This calculator helps with:
- Volume estimation - Calculate cubic yards of crushed stone required for different applications
- Weight calculation - Convert between cubic yards and tons using stone density
- Cost estimation - Determine material costs based on current stone prices
- Project planning - Plan material orders and truck deliveries accurately
- Compaction factors - Account for settling and compaction in calculations
Stone Calculation Process
Crushed stone calculations involve several key steps to ensure accurate material estimation:
1. Area Measurement
Measure length and width of the area to be covered, then determine required depth.
2. Volume Calculation
Calculate volume using length × width × (depth ÷ 12) to convert inches to feet.
3. Unit Conversion
Convert cubic feet to cubic yards by dividing by 27 for standard ordering units.
4. Weight Calculation
Apply stone density factors to convert volume to weight for transportation planning.
Types of Crushed Stone
Standard Crushed Stone
#57 and #411 limestone or granite for general construction and driveway base applications.
Dense Grade Aggregate
High-density stone for heavy-duty applications requiring excellent compaction and drainage.
Light Weight Stone
Volcanic or expanded shale for landscaping and decorative applications requiring less weight.
Drainage Stone
Clean 3/4" stone for French drains, retaining walls, and areas requiring excellent drainage.

Benefits of Using Crushed Stone Calculator
- • Precise Material Planning: Calculate exact crushed stone requirements before starting projects.
- • Cost Control: Avoid over-purchasing and prevent costly material shortages or excess.
- • Delivery Planning: Estimate truck loads and coordinate delivery schedules efficiently.
- • Project Efficiency: Ensure adequate material for complete project completion.
- • Drainage Optimization: Select appropriate stone types for proper water drainage.
Factors That Affect Your Crushed Stone Requirements
1. Project Application
Different applications require different depths and stone types for optimal performance and drainage.
2. Soil Conditions
Poor drainage or unstable soil may require deeper stone layers and additional base material.
3. Traffic Load
Heavy traffic areas need thicker stone layers and denser, more durable stone types.
4. Compaction & Settling
Account for compaction factors to ensure adequate material after settling occurs.
Frequently Asked Questions (FAQ)
Q: How do I calculate crushed stone volume for my project?
A: Multiply length × width × (depth ÷ 12) to get cubic feet, then divide by 27 to get cubic yards. For example, a 10ft × 12ft area at 4 inches thick: 10 × 12 × (4/12) = 40 ft³ ÷ 27 = 1.48 cubic yards.
Q: What is the difference between cubic yards and tons?
A: Cubic yards measure volume while tons measure weight. Crushed stone weighs 1.4-1.6 tons per cubic yard depending on stone type. The calculator converts between volume and weight automatically.
Q: How much extra crushed stone should I order?
A: Order 5-15% extra to account for waste, settling, and compaction. Areas with poor drainage or heavy traffic may need 10-20% extra. The calculator includes an adjustable extra material percentage.
Q: What type of crushed stone should I use?
A: Use #57 stone for drainage, #411 for compact driveways, 3/4 inch for general applications, and dense grade aggregate for heavy-duty projects requiring excellent compaction.
Q: How do compaction factors affect my calculations?
A: Compaction factors account for stone settling after installation. Most projects require 1.05-1.15 compaction factor. Higher factors may be needed for drainage applications.
Q: What truck capacity should I plan for delivery?
A: Most stone delivery trucks carry 15-25 tons per load. Use the calculator's truck loads estimate to plan deliveries and coordinate with suppliers for multiple loads if needed.
