Estimate how many cubic yards of topsoil you need. Each dimension has its own unit selector (in/ft/yd/m).
Topsoil is sold by the cubic yard. Find each area's volume (length x width x depth), divide by 27 for cubic yards, and add about 10% for settling. New beds usually need 4-6 inches; one cubic yard covers about 100 sq ft at 3 inches. Use the unit selector to enter inches, feet, yards or meters.
Use the topsoil calculator for lawns, beds, grading and leveling work. It converts area and depth into cubic yards, then applies a settling allowance and cost per yard.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
