Free Gravel, Topsoil & Cubic Yard Calculator

Planning a landscaping, driveway, or construction project? Use Super Soil USA's free material calculator to estimate how much gravel, aggregate, topsoil, road base, decorative rock, or compost you'll need.

How to Calculate Cubic Yards of Gravel, Topsoil or Compost

To estimate how much material your project needs, measure the length and width of the area in feet. Multiply length × width × depth in inches, then divide by 324 to calculate cubic yards. Whether you're installing driveway gravel, spreading topsoil, adding compost or preparing a road base, our free calculator makes estimating materials easy. Actual tons required depend on the material's density and compaction.
