A 400 ft² poured slab — a 20 by 20 patio — costs $2,241 in Mississippi and $3,465 in Alaska, against a national figure of $2,600.
Concrete work is about half labour, and cement mason pay is published for all 51 jurisdictions, so the table below scales only that half and leaves material at national prices.

The thickness question comes first
The figures price a 4-inch slab on grade: a patio, a shed floor, a walkway.
A driveway that will carry a vehicle wants five or six inches with rebar, and that is not a marginal adjustment. The concrete volume rises by a third to a half, the steel and the deeper base come on top, and the labour to place and finish a thicker pour goes up with it.
A quote that looks cheap against this page is very often quoting four inches for a job that needs six. Ask for the thickness, the base depth and the reinforcement in writing.
Concrete is sold by volume; the pour is sold by area
A 4-inch slab uses roughly one cubic yard per 81 ft², so a 400 ft² pour is about five yards.
Two charges catch people on small pours:
- Short-load fees below a full truck, which is typically nine or ten yards.
- Waiting time if the crew is not ready when the truck arrives.
Two identical patios can differ by several hundred dollars purely on whether the truck waited, and neither figure appears in any published cost guide.
Small pours price badly, and there is a reason
Labour is half this job, and on anything under about 300 ft² the fixed costs dominate. Mobilising a crew, setting forms and the truck itself cost nearly the same for 100 ft² as for 300.
That is why the per-foot price on a small slab looks poor, and why adding the walkway you were putting off until next year is usually cheaper done now than done separately later.
Alaska and Hawaii are at the top for a different reason
Most of this table is wages. The top two entries are wages and freight — cement, aggregate and steel all have to arrive, and that shows up in the material half which the model deliberately does not scale.
Treat those two rows as the most conservative in the table rather than the most precise.
What is not in the price
Thickened edges where a load-bearing wall will sit. A vapour barrier under a heated or interior slab. Rebar mats where an engineer specifies them rather than mesh. Saw-cut control joints beyond standard spacing. And any grading or drainage work around the pour, which on a sloping site can rival the slab itself.
