Estimate topsoil volume, approximate weight, dynamic coverage, bags, extra material, and optional material cost for lawns, gardens, raised beds, and landscaping.
Area multiplied by finished soil depth gives base volume. CalcRocket normalizes dimensions to meters and calculates one canonical cubic-meter result.
The selected extra or settlement allowance is applied once to base volume. Estimated mass is then derived from recommended volume and the editable density.
volume = length × width × depth × quantityvolume = π × (diameter ÷ 2)² × depth × quantityvolume = area × depth × quantitybase volume × (1 + extra % ÷ 100)recommended volume × densityone cubic yard or cubic meter ÷ depthceiling(recommended volume ÷ bag volume)A 20 ft × 10 ft bed at 6 in depth uses 100 ft³ or 3.703704 yd³. With 5% extra it uses 105 ft³ or 3.888889 yd³. At 75 lb/ft³, estimated weight is 7,875 lb or 3.9375 short tons.
A known 500 ft² area at 4 in depth uses about 166.6667 ft³ or 6.17284 yd³. With 5% extra it uses about 6.48148 yd³.
A 40 m² area at 10 cm depth uses 4 m³. With 5% extra and 1,200 kg/m³ density, it uses 4.2 m³ and weighs an estimated 5,040 kg or 5.04 tonnes.
Depth is normalized automatically, including inches or centimeters. Presets are conveniences, not universal recommendations.
Moisture, organic matter, soil composition, and compaction affect bulk density. Replace the editable example with supplier information.
The extra/settlement field can cover handling or settling without silently stacking separate multipliers.
One cubic yard equals exactly 27 cubic feet. Converting depth before multiplying is essential: 4 inches is one-third of a foot.
Topsoil density can change substantially with moisture, organic content, texture, blending, and compaction. Weight results are estimates based on the density entered.
Coverage is generated dynamically. One cubic yard covers 108 ft² at 3 inches; one cubic meter covers 20 m² at 5 centimeters.
Bag estimates use the volume printed on the selected product and round purchase count upward. No universal bag size or bag weight is assumed.
Optional cost can use cubic yards, cubic meters, short tons, metric tonnes, or whole bags. It excludes delivery, spreading, grading, labor, tax, and equipment.
Enter the area shape, dimensions or known area, finished depth, quantity, extra allowance, and editable density.
Calculate cubic feet using compatible dimensions and divide by 27, or let CalcRocket normalize the measurements.
There are exactly 27 cubic feet in one cubic yard.
Coverage depends on depth. The calculator generates coverage from the selected depth rather than using a universal value.
It depends on density, which varies with moisture, composition, and compaction. Use supplier density when possible.
Moisture, organic matter, clay or sand content, blending, and compaction all affect bulk density.
Use rectangular mode: multiply inside length by width by fill depth.
Enter the finished depth appropriate for your specific plants, site, and project guidance.
You may use the editable extra/settlement allowance; the appropriate value depends on the soil and project.
Enable bags, enter the product's bag volume, and the recommended volume is divided by it and rounded upward.
Volume is multiplied by the editable density and then converted to short tons or metric tonnes.
No. Optional pricing is material-only.
