Basic concrete slab cost. I'll base my price on what my actual estimate would be to install a 6 thick concrete slab for one of my customers. Base cost for a 6 thick concrete slab -- $4.00 dollars per square foot --. Take the length of the concrete slab x the width of the slab to get the. total square footage. Multiply the total square footage by 4 (dollars) to get the total price.
The average cost of a concrete slab will be between $5 and $7 dollars per square foot or $135 and $189 per cubic yard.he cost of concrete slabs also needs to include the cost of excavation. A base of gravel that is normally four inches thick is laid after the area is dug and footings are put in place. The cost of gravel is generally $0.79 per square foot.
