Landscape Material Calculator

Estimate bulk landscape material volume, weight, bag equivalents, and wheelbarrow trips.

For uneven ground, spillage, and settling.

How this estimate works

  • Base volume in cubic feet = area in square feet × depth in inches ÷ 12.
  • The selected waste allowance is added to base volume, then volume is divided by 27 for cubic yards.
  • Estimated tons use a typical material density; bag equivalents use 2-cubic-foot bags and trips are rounded up.

Before you begin

  • Density varies with particle size, compaction, moisture, and supplier product; supplier figures control for ordering.
  • The calculator cannot account for slopes, irregular beds, excavation, or local delivery load sizes.
  • Bag equivalents are volume equivalents, not a recommendation to buy bagged material instead of bulk.
