According to our concrete slab material estimator, the average minimum cost per square foot of a concrete slab is $1.36 and the maximum is $1.88. By comparison, the price per square foot for a cement slab is $5.50. Just know that even if you do not hire a pro, there are additional costs that come with all concrete slab projects.
Basic, construction-grade concrete costs about $5 to $10 per square foot, including installation. Opting for fancier, decorative versions such as stamped or colored concrete will add several dollars per square foot to the price. Very high-end concrete could cost as much as $15 per square foot.
