Bulk Estimator

Work out how much mulch, gravel, topsoil, sand or asphalt to order — with every density figure sourced and every result given as a range.

Every calculator shows the formula it uses, the density range it assumes and where that number comes from — so you can check the maths yourself.

• Asphalt Calculator

  Enter your area and paving depth to get the tonnage, volume and truckloads you need — with the density we used and where it came from shown underneath.

• Topsoil Calculator

  Enter your area and depth to get cubic yards, short tons and bag counts — and choose whether your soil is loose, in place or compacted, because it changes the weight by up to 60%.

• Crusher Run Calculator

  Work out the tonnage of crusher run or dense-graded aggregate base for a driveway, road or pad — using a density range that two separate state DOTs agree on.

• Paver Base Calculator

  Work out the aggregate for both the compacted base layer and the bedding course under pavers — calculated separately, because they are placed at very different thicknesses.

• Mulch Calculator

  Enter your bed area and the depth of mulch you want. You get cubic yards and bags — and an honest explanation of why no weight is shown.

• Gravel Calculator

  Enter your area and depth to get tonnage, volume, bag counts and truckloads — and choose loose or compacted, because the same gravel weighs 40% more once it is rolled.

• Sand Calculator

  Enter your area and depth to get cubic yards, short tons and bag counts, and choose whether the sand is loose or compacted.

• Compost Calculator

  Enter your area and the depth you want to apply, and get cubic yards, tons and bags — using the compost industry's own published bulk density figures.

• Sod Calculator

  Enter your lawn area to get the number of pallets and rolls you need, including a waste allowance for cuts and edges.

• Fill Dirt Calculator

  Enter the area and how much you need to raise it, and get cubic yards and tons — with the loose and compacted soil densities and their sources.

• Wood Chip Calculator

  Enter your bed area and the depth of mulch you want, and get cubic yards, tons and bags of wood chips.
