Concrete Slab Cost: What to Expect in 2026
A concrete slab costs $4–$8 per square foot for a basic pour, or $115–$165 per cubic yard for material. A 10×12 ft patio slab costs roughly $500–$1,000 DIY or $1,500–$3,000 professionally installed.
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 with our concrete calculator.
How Much Does Concrete Cost?
Concrete pricing has two components: the material (ready-mix) and the labor to form, pour, finish, and cure it.
| Component | Cost Range |
|---|---|
| Ready-mix concrete (per cubic yard) | $115–$165 |
| 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, including material and professional labor:
| Project | Typical Size | Thickness | DIY Cost | Installed Cost |
|---|---|---|---|---|
| Patio slab | 10 × 12 ft (120 sq ft) | 4" | $350–$700 | $1,200–$2,400 |
| Shed pad | 10 × 10 ft (100 sq ft) | 4" | $300–$600 | $1,000–$2,000 |
| 1-car garage floor | 12 × 24 ft (288 sq ft) | 4–6" | $800–$1,600 | $2,500–$5,000 |
| 2-car garage floor | 24 × 24 ft (576 sq ft) | 4–6" | $1,600–$3,200 | $5,000–$9,000 |
| Driveway | 12 × 40 ft (480 sq ft) | 4–6" | $1,400–$2,800 | $4,000–$8,000 |
| Sidewalk | 4 × 30 ft (120 sq ft) | 4" | $350–$700 | $1,000–$2,000 |

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
- Minimize the thickness. A 4-inch slab works for most patios and walkways. Only go 5–6 inches for vehicle traffic (garages, driveways).
- 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).
Gravel Base Under Concrete
Every concrete slab needs a compacted gravel base. This provides drainage, prevents frost heaving, and gives the slab a stable foundation:
- Recommended depth: 4 inches of compacted gravel (6 inches in cold climates).
- Best material: Crusher run (#57 stone) — angular pieces that compact tightly.
- 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, place and compact gravel base, lay rebar/mesh.
- Day 2: Pour concrete, screed, float, edge, broom finish.
- Days 3–7: Cure under plastic or wet cure. Do not walk on it for at least 24 hours; no vehicles for 7 days.
- Day 28: Full strength reached. Concrete continues to harden for months, but 28 days is the design benchmark.
