Topsoil Calculator

Calculate topsoil for rectangles, squares, circles, triangles, trapezoids, borders, and known areas. Add multiple sections with individual depths and sum them in one total. Formula: Cubic Yards = (Area × Depth in inches) ÷ 324.

Built-in presets for topdressing (0.25–0.5 in), existing garden beds (2 in), new lawns (4–6 in), new garden beds (8 in), and raised beds (10–12 in). Enter any custom depth for complete control.

Get results in cubic yards, cubic feet, and cubic meters for bulk orders. Convert the same volume into bags for 0.75, 1, 1.5, and 2 cu ft sizes. A standard 40 lb bag holds about 0.75 cu ft, with 36 bags per cubic yard.

Estimate weight in short tons using dry and wet topsoil densities. A cubic yard of topsoil weighs roughly 1.0–1.35 tons, depending on moisture. Add a customizable waste factor (5–10%) for settling and uneven grade.

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. Typical topsoil costs $15–$30 per cubic yard in bulk, while bagged runs $2–$6 per 40 lb bag.

Work in feet, inches, yards, meters, and centimeters. Get output in cubic yards, cubic feet, cubic meters, liters, tons, and bags. All calculations, bag counts, and cost estimates update instantly. Fully functional offline.
