How to calculate concrete bag count
This calculator finds how many bags of concrete mix are needed for a project by dividing the total concrete volume by the yield of a single bag.
How the calculation works
Bag count = Total volume ÷ Yield per bag. Common 80 lb bags yield about 0.6 cubic feet each; 60 lb bags yield about 0.45 cubic feet.
Example
A project needing 12 cubic feet of concrete, using 80 lb bags (0.6 cu ft yield each): Bag count = 12 ÷ 0.6 = 20 bags.

Pro Tips for Concrete Bag Count
- Confirm the yield printed on your specific bag product, since it varies by bag weight and mix formulation.
- For anything beyond a small project, ready-mix delivery is usually more economical and less labor-intensive than mixing many individual bags.
Common Concrete Bag Count Mistakes to Avoid
- Using a generic bag yield instead of the actual figure printed on your specific product's packaging.
