An itemized contractor pricing breakdown for concrete slabs, driveways, and patios per square foot—covering excavation, subbase gravel, rebar, labor, and decorative finishes.
Turnkey Installed Flatwork: $6.00 to $12.00 per square foot.
For standard residential flatwork (a 4-inch broom-finished patio, walkway, or driveway), professional installation averages $8.00 to $10.00 per square foot. Stamped or custom stained patterns range from $12.00 to $25.00+ per square foot.

Itemized Cost Breakdown for a Standard 4" Concrete Pour
Homeowners frequently ask why an installed pour costs $8 to $10 per square foot when ready-mix concrete only costs ~$1.85 per square foot in material. The table below itemizes every phase of a professional residential installation:
| Installation Component | Estimated Cost / sq ft | % of Total Cost | What It Covers |
|---|---|---|---|
| Site Prep & Excavation | $1.00 – $2.50 | 15% – 25% | Grading dirt, sod stripping, establishing 1% drainage slope |

| Formwork & Staking | $0.75 – $1.25 | 8% – 12% | 2×4 or 2×6 lumber, corner bracing, expansion joints |
| Reinforcement (Rebar / Mesh) | $0.50 – $1.25 | 6% – 12% | #4 steel rebar grid @ 18" OC elevated on chairs |
| Ready-Mix Concrete Material | $1.50 – $2.50 | 20% – 25% | Delivered 3,500 PSI ready-mix (0.01235 yd³/sq ft) |
| Finishing Labor & Saw Joints | $2.50 – $4.50 | 25% – 35% | Pouring, screeding, bull-floating, edging, broom finish |

Total Installed Project Costs by Common Slab Dimensions
This table calculates realistic turnkey budget ranges across common residential flatwork dimensions (based on a standard 4" broom-finish pour):
| Project Size & Description | Square Footage | Concrete Volume (+10%) | DIY Material Cost | Turnkey Contractor Cost |
|---|---|---|---|---|
| 6 × 6 ft Generator / Utility Pad | 36 sq. ft. | 0.49 yd³ (22 bags) | $180 – $280 | $600 – $950 (Min fee) |

Major Factors That Increase Per-Square-Foot Pricing
1. Site Accessibility & Pumping
If the concrete transit truck cannot back directly up to the forms, concrete must be transported via wheelbarrows or a motorized concrete pump. Boom pump truck rentals add $600 to $1,200 flat (+$1.50 to $2.50/sq ft).
2. Slab Thickness & Structural Loading
Increasing thickness from 4 inches to 6 inches adds 50% more concrete volume and requires heavier #4 rebar, increasing project costs by $1.50 to $3.00 per square foot. See our guide on how thick should a concrete slab be.
3. Old Concrete Demolition & Removal
Tearing out an existing cracked driveway or patio adds $2.00 to $5.00 per square foot for hydraulic breaker labor, dumpster rentals, and landfill recycling fees.
4. Decorative Stamping & Sealing
Stamped patterns require color hardeners, powdered release agents, polyurethane stamp mats, and high-solids solvent acrylic sealers, adding $6.00 to $15.00 per square foot over standard broom finishes.
Frequently Asked Questions About Concrete Cost Per Square Foot
How much does it cost to pour a concrete slab per square foot in 2026?
In 2026, the average cost to have a professional contractor install a standard 4-inch concrete slab with a broom finish ranges from $6.00 to $12.00 per square foot. Decorative finishes (stained, exposed aggregate, or stamped) range from $8.00 to $20.00+ per square foot.
What is the difference between raw material cost and installed cost per square foot?
Raw ready-mix concrete material costs only $1.50 to $2.50 per square foot for a 4-to-5-inch slab ($130 to $180 per cubic yard). The remaining $4.50 to $9.50 per square foot covers excavation, crushed aggregate subbase, formwork lumber, steel rebar reinforcement, pouring labor, screeding, trowel finishing, and saw-cutting control joints.
How much does a 20x20 concrete slab cost to install?
A 20×20 foot concrete slab (400 sq. ft.) typically costs between $2,800 and $4,800 fully installed for a 4-inch patio or light driveway ($7 to $12/sq ft). For a heavy-duty 5-to-6-inch garage floor or RV pad with #4 rebar, expect total installed costs between $3,600 and $5,600.
How much does it cost to remove and replace existing concrete?
Demolishing, breaking up, and hauling away existing concrete flatwork adds $2.00 to $5.00 per square foot to the total project cost. For a 400 sq. ft. driveway replacement, budget an additional $800 to $2,000 for demolition and disposal fees.
Why do small concrete projects cost more per square foot?
Contractors face fixed mobilization costs (transporting skid steers, form lumber, tools, and paying minimum ready-mix truck charges). A 50-to-100 sq. ft. walkway may cost $12 to $18 per square foot due to minimum project fees, whereas a 1,000 sq. ft. commercial pad averages $6 to $8 per square foot.
