Does this account for compaction?
No -- enter the depth you intend after compaction, not the loose (pre-compaction) depth.
Gravel Base Calculator
Gravel base volume from area and compacted depth.
Order — cu yd of gravel base for — sq ft at — in deep.
Area source
Use the active project's Concrete footprint (base under a slab) or override manually.
Chained slab footprint
Run Concrete first with a rectangular pour to prefill gravel base with its footprint.
