How much do concrete slabs cost?

The cost of a concrete slab generally falls between $3 and $10 per square foot, depending on factors like the thickness of the slab and whether frost walls are included or the slab is floating. For a 500- to 1,000-square-foot house, you can expect to pay around $5,318 for your slab. 

When making pricing decisions — such as choosing between a 4-inch, 5-inch or 6-inch slab — factor in what type of furnishings and interior structures you will put in the house.
