Estimate assumptions

Estimates are for planning and ordering only.
Bag counts are rounded up to whole bags.
Ready-mix yards are rounded up to the nearest 0.25 cubic yard.
Default waste is 10%. Increase it for uneven excavation, spillage, or complex forms.
Verify structural work with a contractor, engineer, or supplier before pouring.

Method and assumptions

The chart uses common manufacturer yield values for general concrete mix bags: 40 lb = 0.30 cu ft, 50 lb = 0.375 cu ft, 60 lb = 0.45 cu ft, and 80 lb = 0.60 cu ft.

One cubic yard is 27 cubic feet. Bag counts are rounded up to whole bags, and the waste column adds 10% before rounding.
