How to estimate
- Measure the area you're covering - length × width.
- Pick the grade or material that matches your project.
- Read the estimated installed cost range for your area.
What drives the cost
- Finish - a plain broom-finished slab is cheapest; stamped, stained or exposed-aggregate finishes cost much more.
- Thickness and reinforcement - a 4-inch slab costs less than a 5–6-inch driveway with rebar or wire mesh.
- Sub-base and grading - excavation, a compacted gravel base and forming are most of the labor.
- Slab size and shape - small or oddly shaped pours cost more per ft²; large flat pours are cheaper.
- Access and tear-out - removing an old slab and hard-to-reach sites add cost.
- Local labor and concrete prices - the biggest regional swings.
Average installed cost
| Grade | Per ft² (installed) | Typical |
|---|---|---|
| Plain slab | $5–$10 | 4-inch broom-finished slab |
| Driveway / reinforced | $8–$15 | Thicker, rebar or mesh |
| Stamped / decorative | $12–$28 | Stamped, stained, aggregate |
Ranges are national averages and vary with region, prep and material - a starting point, not a quote.
Frequently asked questions
- How much does a concrete slab cost?
- Installed, a plain concrete slab runs about $5–$10 per square foot (labor + materials); a reinforced driveway $8–$15, and stamped or decorative concrete $12–$28. A 20×20 ft (400 ft²) plain slab lands roughly $2,000–$4,000. Enter your area above.
- How much does a concrete driveway cost?
- Most standard concrete driveways run about $8–$15 per square foot installed. A 576 ft² two-car driveway lands roughly $4,600–$8,600; decorative or stamped finishes can exceed $20 per square foot.
- Why is stamped concrete so much more expensive?
- Stamped and stained concrete need color, release agents, stamping mats and extra finishing labor, so they run $12–$28/ft² versus $5–$10 for a plain broom finish - often double or more.
- Why is this only an estimate?
- Thickness, reinforcement, sub-base, finish, tear-out and local prices all move the cost. Use this national-average range as a starting point, then get local quotes.
