The Crushed Stone Calculator estimates how much material you need for a landscaping, driveway, or construction project — in tons, cubic yards, and cubic feet. Enter your project's length, width, and depth, then select a material type (crushed stone, gravel, rock, or sand) to get the tons needed and total volume. Add an optional price per ton or cubic yard to see your estimated material cost.

To calculate crushed stone needed, multiply length × width × depth, then convert to cubic yards by dividing by 27. Finally, multiply by the material density (typically 1.7 tons per cubic yard for crushed stone).
Crushed stone is mechanically broken rock with angular edges, while gravel consists of naturally weathered rock fragments with rounded edges. Crushed stone compacts better and is preferred for driveways and foundations.
For residential driveways, crushed stone depth should be 2-4 inches for light traffic and 4-6 inches for heavier vehicles. Commercial applications may require 6-8 inches or more.
¾ inch crushed stone is most commonly used for driveways as it provides good drainage and compaction. Smaller sizes like ¼ inch work well for top dressing and pedestrian areas.
Crushed stone typically costs $20-50 per ton, depending on the type of stone, location, and quantity purchased. Delivery fees may add $50-150 to your total cost.
Crushed stone is typically sold by the ton (weight), but some suppliers also sell by cubic yard (volume). Our calculator provides both measurements to help you compare prices and place orders accurately.
