IQHabUnited States Concrete Concrete Calculator

Concrete calculator

Estimate concrete volume, bags and cost for a slab or footing by area and thickness.

Enter the dimensions and thickness to get volume, bags and a cost range.

How to use it

Choose the shape, enter the dimensions and thickness, pick a mix strength and finish. The tool returns volume in cubic yards, how many 60 lb / 80 lb bags, and an installed cost range by component.

  • 1 cubic yard = 27 cu ft.
  • Ready-mix for large pours; bagged mix for smaller jobs.
  • Order a little extra for waste and sub-grade variance.

Next step

Use the result to plan the pour. Confirm thickness, reinforcement and finish with a contractor before ordering.

These estimates are based on state-level averages, not ZIP-level precision. The final cost varies with your home and local market.
