Soil Calculator

Calculate soil for rectangles, squares, circles, triangles, trapezoids, borders, and known areas. Add multiple beds as separate sections and sum them into one total. The core formula is Cubic Yards = (Area × Depth in inches) ÷ 324.

Built-in presets for lawn topdressing (1–2"), new lawns and sod (4–6"), garden beds (6–12"), raised beds (12–18"), and grading or fill. A new lawn wants 4–6" of quality topsoil, garden beds run 6–12", and raised beds are typically filled 12–18" deep.

Get results in cubic yards, cubic feet, cubic meters, and short tons. Bulk topsoil runs about 1.0–1.2 tons per cubic yard (roughly 2,000–2,400 lb), while wet or compacted soil runs 20–35% heavier. Convert the same volume into 0.75, 1.0, 1.5, 2.0, and 3.0 cu ft bags — a cubic yard equals 27 cu ft, or about 14 two-cubic-foot bags.

Add a customizable waste factor: 5% for a clean, flat site, 10% for settling and uneven grade, and up to 15% for sloped or irregular beds. Industry practice is to order about 10% over because soil settles and a second delivery costs more than the first yard.

Enter your bulk price per cubic yard or bag price to get an instant project cost. Compare bulk delivery against bagged retail side by side. In 2026, bulk topsoil runs about $12–$60 per cubic yard delivered, with screened topsoil typically $18–$40 per cubic yard, while bagged soil is $2–$5 per bag.

Work in feet, inches, yards, meters, and centimeters. Get output in cubic yards, cubic feet, cubic meters, liters, short tons, and bags. All calculations, coverage figures, truckloads, and cost estimates update automatically. Fully functional offline with no internet required.
