How Much Does Concrete Cost in 2026?

The average cost to pour a concrete slab ranges from $4 to $8 per square foot for a basic 4-inch thick installation. This includes the concrete material itself, labor for forming, pouring, and finishing, plus delivery. A typical 20x20 foot patio slab costs between $1,600 and $3,200 at mid-range pricing.

Concrete pricing depends heavily on your project specifications. The mix type affects material costs — standard ready-mix concrete runs about $130 per cubic yard, while high-strength or fiber-reinforced mixes cost $155-$170 per cubic yard. Decorative finishes like stamped concrete can add $8-$12 per square foot beyond the base pour price, making them a significant cost driver for decorative patios and pool decks.

Understanding Concrete Volume

Concrete is sold by the cubic yard. One cubic yard covers 81 square feet at 4 inches thick or 54 square feet at 6 inches thick. Our calculator converts your length, width, and depth measurements into cubic yards automatically, then applies local pricing data to estimate your total project cost. We recommend ordering 5-10% extra to account for spillage and subgrade irregularities.

Reinforcement Options and Their Cost Impact

Reinforcement prevents cracking and extends slab life. Wire mesh ($0.50/sqft) works for patios and walkways. Standard #4 rebar ($0.85/sqft) is recommended for driveways and garage floors where vehicles will be parked. Heavy #5 rebar ($1.25/sqft) suits commercial or heavy-load applications. Fiber reinforcement, mixed directly into the concrete, offers crack resistance without the labor of placing rebar or mesh.
