How much does a 20x20 concrete driveway cost?

A 20x20 concrete driveway (400 sq ft) costs $3,200–$6,400 for a standard 4-inch broom-finish slab. At $8–$16 per square foot, price varies by region, reinforcement, and finish type. Stamped or colored concrete adds $4–$8 per square foot.

How thick should a concrete driveway be?

Residential driveways need 4 inches minimum for cars and light trucks. For heavy trucks, RVs, or motorhomes, use 5–6 inches. Always use 4,000 PSI concrete with fiber mesh or rebar reinforcement.

Is a concrete driveway cheaper than asphalt?

Asphalt is cheaper upfront ($3–$7/sq ft vs $8–$16/sq ft for concrete), but concrete lasts 30–50 years compared to asphalt's 15–20 years. Over the lifetime, concrete is usually cheaper per year. Concrete also increases home resale value more than asphalt.

What Affects Concrete Driveway Cost

1. Thickness

4 inches: Standard for cars and light trucks — most common
5 inches: Heavy SUVs, work trucks — adds ~20% to material cost
6 inches: RVs, dump trucks, commercial — adds ~40% to material cost

2. Reinforcement

Fiber mesh: $0.50–$1/sq ft — standard, prevents hairline cracks
Wire mesh: $1–$2/sq ft — better crack control
Rebar grid: $2–$4/sq ft — best for heavy loads, required in some codes

3. Site Prep

If your contractor needs to remove old asphalt, grade the site, or bring in fill dirt, add $1–$3/sq ft. Tree stump removal, drainage work, or soil correction adds more.

4. Location & Access

Rural areas cost more (longer concrete truck drive). Tight city lots cost more (pump truck needed). Steep driveways cost more (forms are harder). Expect 10–30% variance by region.

Concrete vs. Asphalt vs. Pavers

Material	Upfront Cost	Lifespan	Maintenance
Concrete	$$$	30–50 years	Seal every 2–3 years
Asphalt	$$	15–20 years	Seal every 2 years, resurfacing
Pavers	$$$$	30+ years	Weed control, releveling
Gravel	$	5–10 years	Add gravel annually

💡 Pro Tip

Get at least 3 contractor quotes. Prices vary wildly — I've seen $6/sq ft and $18/sq ft for identical specs in the same zip code. Check reviews, verify insurance, and ask to see a recent job. The lowest bid is rarely the best value.

DIY vs. Professional

Concrete is one of the few projects where DIY rarely saves money. By the time you rent forms, buy concrete, and factor in the risk of a bad pour (which happens fast — concrete waits for no one), a pro is usually worth it.

DIY material cost: $4–$6/sq ft (concrete, rebar, forms)
Pro installed: $8–$16/sq ft
Your time: 2–3 days vs. 1 day for a crew
Risk: Bad finish, cracks, improper slope for drainage
