How Much Does a 20×20 Concrete Driveway Cost in 2026?

How much does a 20×20 concrete driveway cost in 2026? A standard 20×20 concrete driveway — 400 square feet, the classic two-car size — typically costs $2,400–$4,800 for a plain broom finish installed, $4,800–$8,000 for stamped or decorative concrete, and $3,200–$6,400 all-in for a plain driveway when an old driveway must be removed first. The per-square-foot rate behind those totals is $6–$12 for plain concrete and $12–$20 for stamped concrete, with labor, base preparation, and site conditions deciding where in the range your project lands. This guide breaks down the 20×20 driveway cost by finish, thickness, prep work, and region, so you can check any quote in minutes.

A 20×20 driveway is 400 square feet, enough for two cars side by side with room to open doors. It is one of the most common driveway sizes in the US, which means contractors quote it often and the pricing is well established. The total is simply your square footage times the per-square-foot rate, plus extras — and because the size is fixed at 400 square feet, the finish you choose is the biggest decision you will make. For the full single-car breakdown, see our guide to the 10×20 concrete driveway cost.

How Much Does a 20×20 Concrete Driveway Cost by Finish

Finish is the single biggest cost lever on a 20×20 driveway. The same 400 square feet costs $2,400 plain and $8,000 stamped:

Plain broom finish ($2,400–$4,800) is the standard driveway: concrete is poured, leveled, and brushed with a broom for a slip-resistant texture. It is durable, low-maintenance, and the best value for most homeowners. If your priority is a solid driveway at a fair price, this is it.

Colored concrete ($3,200–$6,000) adds pigment mixed through the whole slab, so the color cannot peel or wear off the surface the way a coating can. It costs $800–$1,200 more than plain on a 20×20 slab and is a good middle ground if you want a warmer look without the stamped price.

Exposed aggregate ($4,000–$7,200) washes away the top cement layer to reveal decorative stone. It looks premium, grips well in wet weather, and hides stains better than plain concrete — but it costs more and the rough surface is harder on bare feet.

Stamped concrete ($4,800–$8,000) is pressed with patterns and colored to mimic stone, brick, or slate. It is the showpiece option, and on a 20×20 driveway it roughly doubles the plain price. The trade-off is maintenance: stamped surfaces need resealing every 2–3 years to keep their color and pattern crisp, and cracks are more visible in a patterned surface.

Thickness matters as much as finish. A residential driveway should be 4 inches thick for passenger cars; 5 inches is recommended if pickup trucks or SUVs use it regularly, and 6 inches for RVs or heavy vehicles. Going from 4 to 5 inches adds roughly 25% more concrete — about $300–$600 on a 20×20 slab — but it significantly extends the driveway’s life under heavier loads. Do not let a contractor thin the slab to win the bid; a 3-inch driveway cracks early and costs far more to replace than the savings were worth.

What the 20×20 Price Includes — and What It Does Not

A typical installed quote includes excavation to depth, a compacted gravel base (usually 4 inches), forming, concrete, pouring, finishing, and basic control joints. These items are often priced separately:

The all-in math for the typical job. Plain broom finish ($2,400–$4,800) + old driveway removal ($600–$1,200) = $3,000–$6,000, and adding basic grading or a first sealing application brings most real projects to the $3,200–$6,400 all-in range in the quick-answer table. If your quote is for new construction on bare ground with no removal, the plain total of $2,400–$4,800 is the number to compare against — do not let a contractor pad it with a removal charge that does not apply.

Site conditions move the price. A flat lot with good access costs the least. A steep lot, a narrow side yard that blocks truck access, soft or clay soil that needs extra base, or tree roots in the pour area can each add several hundred dollars. If one quote is far above the others, ask what site condition they priced that the others did not — and if one quote is far below, ask what they left out, usually base preparation or reinforcement.

20×20 Driveway Cost by Region

Concrete material costs are fairly uniform nationally, so regional differences are almost entirely labor and delivery distance. In cold climates, air-entrained concrete and a deeper base are standard to resist freeze-thaw damage — that is a real cost, not padding, and skipping it shortens the driveway’s life.

Concrete vs Asphalt for a 20×20 Driveway

Concrete costs roughly 20–30% more upfront than asphalt for the same 20×20 slab, but it lasts roughly twice as long and needs no resurfacing. Over 30 years, concrete is usually the cheaper driveway even though it costs more on day one. Asphalt wins only when the upfront budget is the binding constraint, or when a flexible surface is needed over shifting soil.

DIY vs. Hiring a Pro

DIY saves roughly the labor slice — $1,000–$2,500 on a 20×20 slab — but concrete is unforgiving: it sets in hours, finishing mistakes are permanent, and a wrong slope sends water toward your garage instead of the street. Most homeowners are better off hiring a pro for a full 20×20 pour and reserving DIY for small patches and repairs. Whatever you choose, do not drive on a new driveway for at least 7 days, and wait the full 28 days before parking heavy vehicles on it.

Money-Saving Tips

1. Get three quotes on the same basis: same finish, same thickness, same base depth, same removal scope. 2. Confirm thickness and reinforcement in writing. A 4-inch slab with mesh or rebar is the minimum for a driveway that lasts. 3. Choose plain broom finish unless a decorative look is worth roughly double the price to you. 4. Schedule in the off-season. Concrete crews are busiest in spring and summer; late fall scheduling can be cheaper in mild climates. 5. Combine the driveway with other concrete work. A sidewalk or patio poured in the same visit shares delivery and crew costs. 6. Seal on schedule. A $200–$500 sealing every 3–5 years prevents stains and freeze-thaw damage that cost thousands to repair. 7. Fix drainage before pouring. Water pooling under a new slab undermines the base and cracks the concrete — grading first is cheaper than replacing later.

Frequently Asked Questions

How much does a 20×20 concrete driveway cost?

Typically $2,400–$4,800 for a plain broom finish installed (400 square feet), $4,800–$8,000 for stamped concrete, and $3,200–$6,400 all-in for a plain driveway with old driveway removal.

How many square feet is a 20×20 driveway?

400 square feet — 20 feet wide by 20 feet long, the classic two-car driveway size.

How thick should a 20×20 concrete driveway be?

4 inches for passenger cars, 5 inches if pickup trucks or SUVs use it regularly, and 6 inches for RVs or heavy vehicles. Thicker slabs cost more but last significantly longer under heavy loads.

How long does a 20×20 concrete driveway take to install?

The pour itself takes 1–2 days, but the full timeline is 7–10 days: 1–2 days for excavation and base preparation, 1–2 days for forming and pouring, and 5–7 days of curing before light vehicle use. Full concrete strength is reached at 28 days.

Is a concrete driveway cheaper than asphalt?

No — concrete costs about 20–30% more upfront for a 20×20 slab ($2,400–$4,800 plain versus $2,000–$4,000 for asphalt). But concrete lasts 25–50 years versus 15–20 for asphalt and needs no resurfacing, so it is usually cheaper over its full life.

Do I need a permit for a 20×20 concrete driveway?

It varies by city: permits typically cost $50–$300 where required, and some areas require none for a like-for-like replacement. Check with your local building department before pouring.

The Bottom Line

For a 20×20 concrete driveway in 2026, budget $2,400–$4,800 for a plain broom finish, $3,200–$6,000 for colored concrete, and $4,800–$8,000 for stamped concrete — then add $600–$1,200 for old driveway removal if it applies, for an all-in plain project of $3,200–$6,400. Get three quotes on the same finish, thickness, and base depth, confirm reinforcement and removal scope in writing, and remember that the per-square-foot rate is your best check: if the math does not work at $6–$12 per square foot for plain concrete, the quote does not work either.
