Concrete Estimator

Enter element dimensions, rebar size, and mix design to get concrete volume in CY, rebar weight, formwork area, and a complete cost estimate.

Concrete Elements

CY Conversion

1 CY = 27 cubic feet

4" slab: 1 CY per 81 SF

6" slab: 1 CY per 54 SF

8" slab: 1 CY per 40.5 SF

Always order 5–8% extra
