Formula, assumptions & limitations

Inputs used: Area (sq ft); Depth (in); Settling allowance (%); Bag size (cu ft); Price per bag ($); Bulk price per cu yd ($).

Method: Area × depth converts to cubic feet, with a settling allowance before bag and bulk conversions.

Compaction and soil blend change actual yield. Delivery, amendment, grading, and labor are excluded.

How this tool works

Area × soil depth produces cubic volume, which is converted to cubic yards and increased by the selected overage.

Limits to know

The geometric loose-volume estimate assumes one uniform depth. Settlement, compaction, amendments, grading, moisture, supplier rounding, and delivery minimums can change actual yield.
