Tool-first calculator

Concrete cost calculator: slab, driveway, and patio, installed.

Pick the pour, set the dimensions, choose your metro. The calculator prices the installed job from FatBook's v3 cost index, built on BLS trade wages, Craftsman labor hours, tracked material prices, and verified permit fees. It runs the bag and ready-mix math alongside, so you can weigh a DIY pour against a contractor's number before anyone quotes you.

How to read this result
  • The installed figure is the full contracted job for your metro: labor, materials, base prep, forms, finishing, permit, overhead, and a normal margin.
  • The DIY line is material math only. Bags stay practical for patch work and small pads. Ready-mix wins once volume passes a couple of yards, but minimum-load fees bite below three.
  • The gap between the two is what a crew earns: excavation, forms, screeding, finishing, curing, disposal, and the schedule risk they carry.

What a concrete pour costs installed.

National averages for the typical project size of each pour, from the 2026-08-19 release. Every figure is a modeled installed price: Craftsman labor hours priced at BLS metro wages, materials tracked against producer price indices, plus permit, overhead, and normal margin.

Concrete slab cost by metro.

A standard 400 square foot concrete slab averages $5,274 installed nationally. Across the metros FatBook tracks, the same pour runs from $4,638 in Miami to $7,592 in San Francisco. Wages drive most of that spread, which is why the calculator prices labor from BLS data for your metro instead of applying one national number.

What moves a concrete bid.

Thickness sets the volume, and volume sets the truck bill. A 4 inch slab handles foot traffic and cars; parking a truck or an RV usually means 5 to 6 inches and a stronger mix, which raises material cost by a third before labor changes at all. Reinforcement is the next fork: wire mesh is cheap insurance on patios, while driveways and garage slabs justify rebar on chairs. Site access decides how much of the day goes to wheelbarrows. A pump truck adds a few hundred dollars but saves hours when the pour sits behind a fence line. Tear-out is the quiet budget killer, which is why replacement pours in the index run roughly 50 percent over new work of the same size. And small pours pay a short-load fee once the truck rolls for less than three yards, so batching a sidewalk with a patio pour usually beats doing them a month apart.

Concrete cost questions, answered from the data.

How much does a concrete slab cost per square foot?

The index puts an installed slab at about $13.18 per square foot nationally, with the full job ranging $11.88 to $14.59 per square foot by metro and site conditions. That figure covers labor, concrete, forms, base prep, finishing, permit, and normal contractor overhead, so it sits well above bare material math.

How much does a 20x20 concrete slab cost?

A 20 by 20 slab is 400 square feet, which is the typical project size in the index. Installed, it averages $5,274 nationally with a range of $4,751 to $5,837. Pick your metro in the calculator above for the local figure.

How much does DIY save on a concrete pour?

Materials, forms, and base for the typical slab run about $2,089 of the $5,274 installed average. The remaining $3,185 pays for labor ($1,080 of it), overhead, and margin. DIY keeps that difference if you can handle excavation, forms, screeding, and finishing before the truck's clock runs out. Concrete does not offer a second attempt.

How much more does stamped concrete cost?

Stamped concrete runs about 28 percent over a plain broom-finish patio: $7,348 versus $5,721 for the typical project nationally. The premium buys pattern work, color hardener, release agent, and sealing labor.

Does a driveway cost more than a patio?

Per square foot they land close together: about $12.76 for a driveway and $14.30 for a patio, installed. Driveways usually need thicker pours and stronger base prep, while patios spend more on finish. Replacement pours cost roughly half again as much as new work because tear-out and disposal come first.
