Estimate the volume, tons and cost of gravel for a project, with a labor budget. Each dimension has its own unit selector (in/ft/yd/m).
Find each area's volume (length x width x depth, or half that for a wedge, or pi x radius squared for a circle), divide by 27 for cubic yards, then multiply by the material density for tons. Use the unit selector on any field and the material dropdown to set density. The budget planner adds a labor estimate and a line for other project costs.
Use the gravel calculator for driveways, paths, pads, drainage areas and decorative rock beds. It estimates cubic yards, tons, labor hours and total project budget from the dimensions and density you enter.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
