Measure finished dimensions
Use the final formed or laid-out dimensions whenever possible. Field measurements usually beat drawing assumptions.

Topsoil Calculator planning notes
Topsoil Calculator results are for material planning. Confirm actual dimensions, product yield, and site requirements before ordering.
Add a practical waste margin
Waste covers uneven base, cuts, spillage, and small field changes. The right margin depends on the project and material.
How to use it
Keep the estimate tied to field measurements
Measure area
Use the finished length and width or total square footage of the material area.
Enter depth
Use compacted or installed depth, not loose pile height, when planning coverage.
Check local density
Tons are approximate because moisture and supplier source change material weight.

FAQ
Concrete estimating questions
How does the topsoil calculator work?
Enter area and depth, then the calculator converts volume into cubic yards and an approximate tonnage using common material density assumptions.
Should I add extra material?
Yes. Add a small allowance for compaction, uneven grade, spreading loss, and field measurement variation.
Why are tons approximate?
Material weight changes with moisture, gradation, compaction, and supplier source. Use supplier scale weights for final ordering.
