Soil Calculator

Formula

• Soil planning starts with geometry: area first, then depth, then conversion into volume and cost.
• Core relationship: Soil volume = Area × Depth.
• If needed, convert volume to weight using density: Weight = Volume × Density.
• Input definitions: • Length: used to estimate required soil volume, weight, or cost • Width: used to estimate required soil volume, weight, or cost • Depth: used to estimate required soil volume, weight, or cost • Soil Density: used to estimate required soil volume, weight, or cost • Bag Size: used to estimate required soil volume, weight, or cost • Price per Volume: used to estimate required soil volume, weight, or cost
• Units tip: use consistent units before multiplying; convert depth into the same unit family as area dimensions.
• Budget estimate: Cost = volume price × volume, or mass price × mass when density is known.
• Practical tip: split irregular yards into smaller rectangles, sum their areas, then continue with depth.

Example Soil Estimate

Example workflow: calculate area from site dimensions, multiply by target depth to get soil volume, then convert to weight if density is available. Use your unit price to estimate the full material budget before purchase.
