Concrete Calculator
Estimate how much concrete you need for slabs, footings, walls, and columns, then see cubic yards, bag counts, and cost in one clear result.
Pick the pour type that matches your job, then compare cubic yards, bags, and cost in one place before you call a supplier or buy bags.
Estimate concrete
Choose the pour type first, then enter the dimensions that match the job.
Main result
Estimated concrete
1.6 yd³
Cubic yards stay primary because they travel best into ready-mix quotes, while metric volume and bag counts remain visible for smaller jobs and double-checks.
Cubic feet
43.2 ft³
Cubic meters
1.22 m³
60 lb bags
96
Rounded to whole bags.
80 lb bags

Useful for fewer bags on smaller pours.
50 lb bags

Before you order
Results include the waste allowance from the advanced section. Bag yield can vary by mix, and larger pours are usually better checked against ready-mix ordering.
