Concrete Slab Cost (2026 Pricing Guide)

Pouring a concrete slab runs $4.00–$12.00 per square foot installed for plain, broom-finished concrete. A standard 12×16 ft patio costs $768–$2,304. Thickness, reinforcement, and finish are the three numbers that move your quote — not the labor.

The honest answer

Concrete is the more durable, more expensive cousin of asphalt. A 4" residential slab over compacted gravel lasts 30+ years if poured correctly. Asphalt under similar conditions lasts 15–20. The catch: concrete costs roughly 1.8–2.2× asphalt per square foot, and concrete cracks are visible forever — asphalt patches blend in.

For indoor or covered slabs (garage floors, basements, sheds), concrete wins by default — asphalt isn't even an option. For outdoor slabs (patios, walkways, driveways), the choice comes down to climate and aesthetics. Concrete holds in hot southern climates where asphalt softens above 90°F. Asphalt flexes in cold freeze-thaw climates where concrete cracks.

Pricing breaks down roughly: 25% concrete material, 20% labor and finishing, 15% base prep and gravel, 12% reinforcement, 10% forms and stakes, 8% disposal and cleanup, 10% contractor margin and overhead. Decorative finishes (stamped, colored, polished) flip this — finish labor becomes 40–60% of the total.

What you actually get at each price tier

State-by-state pricing (per sq ft)

Per-sq-ft installed cost across all 50 states + DC for a standard residential 4" slab with wire mesh and broom finish. Estimates apply Bureau of Labor Statistics Regional Price Parity (2022, all-items) to the national median of $7.00/sq ft. Highest: DC ($8.47), Hawaii ($8.19), California ($8.12). Lowest: Arkansas ($5.95), Mississippi ($5.95), West Virginia ($6.02).

Source: National median $7.00/sq ft × BLS RPP (2022). Standard 4" slab, wire mesh, broom finish. Add 32% for 6", 65% for 8". Add 30–105% for decorative finishes. Verify with 2–3 local quotes.

Five factors that move your quote

1. Square footage. Mostly linear, with one twist: pours under 100 sq ft pay a minimum-load surcharge ($150–$300) because the concrete truck has to come for a tiny order. Small DIY-replacement projects often cost more per-sqft than mid-size patios for this reason.

2. Thickness. 4" is residential standard (patio, walkway). 6" for garage floors and concrete driveways — adds 30–35% in material + reinforcement. 8" for RV pads, heavy equipment, commercial — adds 60–70%. Don't over-spec: a 6" patio is wasted money, but a 4" garage floor will crack from a parked car.

3. Reinforcement. Wire mesh is residential default (+$0.50–$1.00/sq ft). Rebar 3/8" grid on 16" centers (+$0.80–$1.50/sq ft) is required for slabs 6"+ or any structural pour. Skip both only for patios under 80 sq ft — the slab will telegraph hairline cracks over time without it.

4. Finish. Broom (most common) is the baseline price. Smooth trowel adds 5–10%. Exposed aggregate adds 30–35% (looks like pebbles set in surface). Stamped patterns mimicking brick, slate, or flagstone add 65–85%. Integral coloring stacks another 8–12%. Polished concrete (indoor floors) adds 80–95%.

5. Base prep. Existing solid gravel base saves $0.50–$1.50/sq ft. Most residential pours need 4" of new compacted gravel ($1.00–$1.80/sq ft adder). Slabs in poorly-draining soil need vapor barriers and drainage swales — add $300–$1,200 to the project.

Concrete vs asphalt for driveways — the honest comparison

This comes up so often it deserves its own table. We've costed both in detail; here's the head-to-head.

Bottom line: concrete if your climate is hot or you plan to stay 15+ years, asphalt if your climate has hard winters or you're prepping a house for sale within 5 years.

DIY or hire a pro?

Small slabs (under 100 sq ft, shed pads, small landings) are realistic DIY for someone with concrete experience. You'll need form lumber, stakes, a screed, a float, an edger, and ideally a power trowel. Material costs about $4–$6/sq ft if you buy bagged ready-mix from Home Depot. Truck-delivered concrete saves 30% per sq ft but has a 3-yard minimum (about 80 sq ft of 4" slab).

For slabs over 100 sq ft, hire. Working time on concrete is measured in minutes — a botched finish at the 30-minute mark stays botched forever. Crews of 3–4 can pour, screed, float, and finish a 400 sq ft slab in 3 hours; a solo DIY-er with the same area is racing the cure and usually loses.
