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. 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.
| 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.
