What this calculator does
Enter a required concrete volume in cubic feet or cubic yards to estimate 40 lb, 60 lb, and 80 lb bag counts.
Bag yield assumptions
The estimates use approximate yields of 0.30 cubic feet for 40 lb bags, 0.45 cubic feet for 60 lb bags, and 0.60 cubic feet for 80 lb bags.
How waste works
The selected waste allowance increases the required volume before bag counts are rounded upward to whole bags.
