How this calculator works
Enter your shape and dimensions in feet. Add the depth in inches. The calculator multiplies them out and converts to ton, then adds 10% overage for waste — the industry standard for decorative rock.
Cost shown is a US national average ($90 per ton). Regional pricing pages are coming soon.
