Crushed Stone Calculator
Estimate crushed stone for driveways, paths, drainage and base layers. Adjust the density to match the aggregate from your supplier and enter a local price per ton if you want a material-cost estimate.
Enter project details
Planning estimate only. Confirm local prices, supplier specifications and site conditions before ordering.
Your estimate
Stone density varies by gradation and moisture. Use your supplier’s tons-per-yard figure and local price for the most useful ordering estimate.

Tell us about your gravel / pea gravel / fill work project. ProjectMetrica uses WiserLeads, the Triares/homeyou lead platform, to check whether a participating buyer is available for your project.
- No purchase is required.
- Availability and matching depend on ZIP code and project details.
- ProjectMetrica may receive compensation for a qualifying accepted request.
The form is submitted to ProjectMetrica first and, when an eligible WiserLeads opportunity is accepted, the required lead data is sent to Triares/homeyou. TrustedForm is used to create a consent certificate for the form session. See the Privacy Policy.
How the crushed stone calculator works
Volume = length × width × depth. Tons = cubic yards × material density. Waste is applied before the weight calculation.
For a better estimate
- Crushed stone density varies by gradation and moisture.
- For compacted bases, account for compaction and final grade.
- Bulk suppliers may quote by ton or cubic yard, so compare using the same unit.

Frequently asked questions
How many tons of crushed stone do I need?+
Calculate the cubic-yard volume and multiply it by the density of the specific aggregate. The calculator performs both steps.
What density should I use?+
Use the supplier’s stated density whenever possible. Aggregate density changes with stone type, gradation and moisture.
Should I add extra material?+
A waste or compaction allowance can help cover grading variation, spillage and settlement.
