Cubic Yard Calculator

About Cubic Yard Calculator

Cubic Yard Calculator is a free online tool for homeowners, landscapers and contractors who need to estimate how much soil, gravel, mulch, sand, concrete or asphalt to order. Users enter the length, width and depth of one or more areas in feet, inches, yards, centimeters or meters, and the tool converts them into cubic yards, cubic feet and cubic meters.

The calculator adds a default 10 percent waste allowance, which can be changed to match a project or supplier advice. It also handles circles, triangles and repeated identical areas, and it can estimate weight, bag counts and cost once a material and density are chosen. Results update live as measurements change, and the calculations run in the browser.

What sets it apart is the set of supporting guidance: a coverage table by depth, worked examples, notes on bag yields and a checklist for talking to suppliers. It is built for quick planning, and its estimates are meant to be confirmed with suppliers before ordering.
