Concrete Slab Cost: What to Expect in 2026
A basic installed concrete slab is about $4–$8 per square foot (plain driveway about $6–$8), while ready-mix material alone is about $120–$170 per cubic yard — separate figures. A 10×12 ft patio at 4 inches is roughly $178–$252 in ready-mix material, or about $480–$960 for a basic installed slab.
Concrete is one of the most durable materials you can put down — but it is also one of the most expensive per square foot. Whether you are pouring a patio, shed pad, garage floor, or basketball court, knowing the real cost upfront prevents sticker shock and helps you decide between DIY and hiring a contractor.
This guide covers 2026 pricing for concrete slabs, cost per square foot for different project types, the DIY-vs-pro breakeven, and how to estimate your exact material needs. Use the calculator below, or read on for the full 2026 pricing breakdown.

How Much Does Concrete Cost?
Concrete pricing has two components: the material (ready-mix) and the labor to form, pour, finish, and cure it. As a combined planning figure, a basic installed residential slab is about $4–$8 per square foot, and a plain, basic-finish driveway about $6–$8 per square foot; site preparation, difficult access, thicker slabs, reinforcement, decorative finishes and demolition can increase the total. Keep the categories separate: ready-mix material per cubic yard, material-only totals, and installed price per square foot are not additive.
| Component | Cost Range |
|---|---|
| Ready-mix concrete (per cubic yard) | $120–$170 (broad planning range; supplier, mix, distance and additives can move it) |
| Short-load fee (under 5 yards) | $40–$70 per yard short |
| Concrete pump truck (if needed) | $150–$250/hour |
| Labor (forming + pouring + finishing) | $3–$6 per sq ft |
| Reinforcement (rebar / wire mesh) | $0.15–$0.50 per sq ft |
Cost by Project Type
Here is what typical residential slab projects cost in 2026 — ready-mix material alone (at a 4-inch planning thickness) beside the basic installed price. Thicker slabs, specialty concrete and decorative finishes raise both columns:
| Project | Typical Size | Planning Thickness | Ready-Mix Material | Basic Installed Slab |
|---|---|---|---|---|
| Patio slab | 10 × 12 ft (120 sq ft) | 4" | $178–$252 | $480–$960 |
| Shed pad | 10 × 10 ft (100 sq ft) | 4" | $148–$210 | $400–$800 |
| 1-car garage floor | 12 × 24 ft (288 sq ft) | 4" | $427–$606 | $1,152–$2,304 |
| 2-car garage floor | 24 × 24 ft (576 sq ft) | 4" | $853–$1,209 | $2,304–$4,608 |
| Driveway (plain finish) | 12 × 40 ft (480 sq ft) | 4" | $712–$1,008 | $2,880–$3,840 (at $6–$8/sq ft) |
| Sidewalk | 4 × 30 ft (120 sq ft) | 4" | $178–$252 | $480–$960 |

How to Calculate Concrete Volume
Concrete is ordered in cubic yards. The formula:
Length (ft) × Width (ft) × Thickness (in) ÷ 324 = Cubic Yards
For a 10 × 12 ft patio at 4 inches thick:
10 × 12 × 4 ÷ 324 = 1.48 cubic yards
Always order 5–10% extra. Concrete is one material where running short is genuinely costly — you cannot pause a pour and order more without creating a cold joint.

DIY vs. Hiring a Contractor
Concrete is one of the most labor-intensive DIY projects. Here is a realistic comparison:
| Factor | DIY | Professional |
|---|---|---|
| Material cost | Same | Same (may get bulk discount) |
| Labor | Your time + helpers | $3–$6/sq ft |
| Equipment needed | Forms, screed, float, bull float, edger | Included |
| Finish quality | Variable — concrete is unforgiving | Professional smooth/broom finish |
| Risk | High — no redo if pour goes wrong | Low — warranty / experience |
Ways to Reduce Concrete Costs
- Don't over-build the thickness. Around 4 inches is a common planning thickness for patios and walkways; vehicle areas may justify more depending on loading, soil support and project design.
- Get multiple quotes. Concrete contractor prices vary widely. Get at least 3 written estimates.
- Avoid Saturday pours. Some ready-mix companies charge premium rates for weekend delivery.
- Do your own prep. Excavating, setting forms, and placing gravel base yourself can save $1–$3 per square foot.
- Order the right amount. Use our concrete calculator to avoid over-ordering (wasted money) or under-ordering (cold joints and second truck fees).
- Consider alternatives for some areas. For a patio, pavers can be more budget-friendly for smaller areas and are DIY-friendlier (see our paver patio guide).
Base Under Concrete
Concrete needs stable, uniform support. Base requirements depend on soil conditions, drainage, slab use and local/project requirements. A compacted granular base is commonly used where improved support, drainage or grade correction is needed, but it is not one universal thickness for every slab, and a gravel base alone does not prevent cracking.
- Base depth: Treat it as a planning input — it varies with soil strength, drainage, climate and slab use. Follow your project design or local requirements.
- Material: Angular, compactable granular material is commonly used; the exact material should meet project requirements.
- Cost: Adds $1–$2 per square foot.
Calculate the gravel base separately using our gravel calculator. For details on gravel types and ordering, read our guide on how much gravel you need.
Concrete Finishes & Their Costs
| Finish | Added Cost/sq ft | Description |
|---|---|---|
| Broom finish | $0 | Standard textured, non-slip surface |
| Smooth / troweled | $0–$0.50 | Sleek look, can be slippery when wet |
| Stamped | $3–$8 | Mimics stone, brick, or wood patterns |
| Exposed aggregate | $2–$5 | Surface washed to reveal stone texture |
| Stained / colored | $2–$5 | Integral color or acid stain |
Timeline for a Concrete Pour
- Day 1: Excavate, set forms, prepare and compact the base if your design calls for one, and place any specified reinforcement.
- Day 2: Pour concrete, screed, float, edge, broom finish.
- Days 3–7: Curing — maintaining suitable moisture and temperature so the concrete can keep developing its properties (see ACI's curing FAQ). A seven-day curing period is commonly adequate for normal concrete under conventional conditions, but mix, weather and project requirements can change the method or duration. When the slab can accept foot or vehicle traffic depends on strength development, curing conditions, weather and loading — follow your concrete supplier or contractor's guidance.
- Day 28: 28-day compressive strength is a common testing/reference age; concrete can continue gaining strength beyond that.
Frequently Asked Questions
- How much does a concrete slab cost?
- A basic installed slab is about $4–$8 per sq ft(plain driveway about $6–$8). A basic 10×10 ft (100 sq ft) slab is about $400–$800 installed; small-job minimums, difficult access, site preparation, reinforcement or decorative finishes can push a quote higher. Ready-mix material alone is a separate figure (about $120–$170 per cubic yard).
- How thick should a concrete slab be?
- It depends on the use, loading, soil support and project design. Four-inch and five-inch slabs are common residential examples, not universal requirements. Heavier vehicles, weak soils or project requirements can justify more thickness or structural design, and base requirements depend on soil, drainage and local rules.
- How much does a 10×10 ft slab cost?
- A 100 sq ft slab at 4 inches needs ~1.23 cubic yards of concrete. Ready-mix material alone: about $148–$210. A basic installed slab: about $400–$800, which is not a guaranteed quote and can run higher with small-job minimums, difficult access, site preparation, reinforcement or decorative finishing.
- Can I pour my own concrete slab?
- Yes for small pours under 75 sq ft using bags. For larger pours, order ready-mix. Slabs over 200 sq ft need a truck and 2–3 people to finish before the mix sets.
