Concrete Driveway Cost Calculator

What a concrete driveway costs per square foot in 2026

A poured concrete driveway runs $6 to $12 a square foot for a plain broom finish in 2026, and $12 to $18 for a stamped, colored or exposed aggregate finish. Those numbers cover the concrete itself plus the forming and finishing labor. They do not cover tearing out the old driveway, fixing the base under it, or handling water, which is where most budgets come apart.

The concrete material alone is a smaller share than most people expect. Ready-mix concrete delivered to a residential job runs about $120 to $180 a cubic yard in 2026 depending on the region and the mix strength. Everything else in the price is labor, equipment, base material and disposal. That is why two driveways of the same size can be thousands of dollars apart.

A two-car driveway is usually 400 to 600 square feet. At the middle of the range that puts a plain replacement in the $6,000 to $9,000 band before tear-out, and higher in coastal and high-cost metro areas. For the technical side of mix design, thickness and jointing, the American Concrete Institute and the National Ready Mixed Concrete Association publish the guidance contractors work from, and your local building department sets the permit rules.

How the total is built: area, thickness and rate

Every driveway price starts the same way: how many square feet, how thick, and what rate the contractor charges per square foot for the finish you picked.

• Area is length times width. A 40 foot long, 16 foot wide driveway is 40 x 16 = 640 square feet.
• Volume is area times thickness, converted to cubic yards because concrete is sold by the yard. A cubic yard is 27 cubic feet, so 640 square feet at 4 inches is 640 x (4 / 12) / 27 = 7.9 cubic yards.
• Waste allowance matters because the subgrade is never perfectly flat. Add 5 percent and the order becomes 7.9 x 1.05 = 8.3 cubic yards, and most contractors round up to a quarter yard when they call the plant.

Concrete weighs about 4,050 pounds a cubic yard, so that 7.9 yard pour is 7.9 x 4,050 = 31,995 pounds of material, or 31,995 / 2,000 = 16 tons, that has to be placed and finished by hand. That weight is the reason labor dominates the price and the reason a 6 inch slab costs more than half again as much as a 4 inch one.

Where the money goes on a 640 square foot job

Here is the full job for the 640 square foot driveway above, priced at the middle of each 2026 range. This is the kind of breakdown worth asking a contractor to match, line for line.

Add the first four lines and the job is 5,760 + 320 + 1,280 + 2,560 = 9,920 dollars, which is 9,920 / 640 = 15.50 dollars a square foot. That total is higher than the $6 to $12 headline rate, and this is the single most common surprise in driveway pricing: the advertised per-square-foot number usually describes the pour, not the project.

The calculator applies a range on top of the subtotal, because two contractors in the same town can be 9,920 x 0.85 = 8,432 dollars and 9,920 x 1.15 = 11,408 dollars apart on identical work. Prices vary enormously by region, so treat every figure here as a planning band and get written bids from local contractors before you commit.

Thickness and reinforcement: two specs that move the price

Thickness is the specification that quietly moves the price, because it costs you twice: more concrete and more labor to place and finish it.

Going from 4 inches to 6 inches on 640 square feet takes the order from 7.9 to 640 x (6 / 12) / 27 = 11.9 cubic yards, which is 11.9 - 7.9 = 4.0 cubic yards more. At $150 a yard delivered that is 4 x 150 = 600 dollars of extra material, and the rest of the surcharge is the extra placing and finishing labor.

Reinforcement is the second lever. Welded wire mesh is standard on residential driveways and adds roughly $0.40 to $0.80 a square foot. A rebar grid on 18 inch centers is stronger and adds about $1.50 to $3.00 a square foot, and it is what you want on expansive clay, on a poorly drained base, or anywhere a loaded truck will park. Neither one keeps a slab from cracking in the wrong place; control joints do that. Joint spacing is normally two to three times the slab thickness in feet, so a 4 inch slab is jointed every 8 to 12 feet.

The line items people forget: tear-out, base and drainage

Ask any contractor which line homeowners forget and the answer is almost always the same three: getting rid of the old slab, building the base under the new one, and moving the water.

• Tear-out and hauling. Breaking up and removing an existing slab runs $3 to $8 a square foot in 2026, including disposal. Dump fees are charged by weight, and concrete is heavy, so a 640 square foot driveway at 4 inches sends about 16 tons to the landfill.
• Base preparation. Excavation, grading and a compacted gravel base run $1 to $3 a square foot. If the soil is clay, if the old base has failed, or if the driveway has settled, that number climbs and the fix has to happen before any concrete is ordered.
• Drainage. Water sitting under or against a slab is what destroys it. A swale, a French drain or a catch basin is a separate line item, typically $500 to $2,000, and skipping it to save money is how a new driveway fails in five years. The EPA green infrastructure guidance covers permeable and drained surfaces that reduce runoff.
• Permits and the apron. Many cities require a permit, and some require the driveway apron where it meets the street to be rebuilt to a public standard. That piece is priced by the city, not the contractor.

These lines are also the ones that change with what the crew finds once the old slab is gone. A good contract says what happens if the base fails, and how much the fix costs per square foot, before work starts.

Size, shape and access: why two same-size jobs differ

Two 640 square foot driveways can be quoted $3,000 apart for reasons that have nothing to do with the concrete.

• Load size. Plants charge a short-load fee under roughly 4 to 5 cubic yards, so a small patio or a narrow walk-up costs more per yard than a full truck.
• Truck access. If the ready-mix truck cannot reach the forms, the concrete has to be pumped or wheelbarrowed. A pump truck is a few hundred dollars for a half day and over $1,000 for a full day.
• Demo access. A bobcat that can drive straight onto the slab is cheap. Hand work behind a fence, or hauling out in small loads, is not.
• Shape. Curves, radii, steps and a widened turnaround mean more forming time and more hand finishing. Straight rectangles are the cheapest square footage you can buy.
• Slope. A driveway that has to be cut into a hill needs excavation and sometimes a retaining edge, and one that sits low needs fill brought in.

Width drives cost more than people expect. A single-car driveway is about 12 feet wide, a two-car is 16 to 24 feet, and going from a 16 foot to a 24 foot two-car driveway on a 40 foot run adds 40 x 8 = 320 square feet, which at $15.50 a square foot installed is 320 x 15.50 = 4,960 dollars.

How to read a contractor quote and what to ask

A quote you can compare is a quote that states the specifications. When you have three bids in hand, check that each one answers the same questions.

• Thickness in inches, written down, not "standard".
• Concrete strength and mix. Residential driveways are commonly 3,000 to 4,000 PSI, and 4,000 PSI with air entrainment is the usual call where the ground freezes.
• Reinforcement, spelled out as welded wire mesh or a rebar grid with the spacing.
• Base depth, usually 4 to 6 inches of compacted gravel.
• Control joint layout and a sealer, plus how the slab will be cured.
• Who pulls the permit and whether the street apron is included.
• A written warranty on cracking and settlement, and what it does and does not cover.

Be careful with a bid that is far below the others. The usual causes are a thinner slab, no base work, no tear-out, or a crew that will be there for a "cash" price with no insurance. Ask what is excluded rather than what is included, and the gap usually explains itself.

When concrete is not the cheapest option

Concrete is not always the cheapest surface, and it is not always the best value either. Compare on cost per year, not cost per job.

• Asphalt runs about $4 to $8 a square foot installed, so 640 square feet at $7 is 640 x 7 = 4,480 dollars. It needs sealcoating every 3 to 5 years and is usually resurfaced sooner than concrete is replaced.
• Gravel runs $1 to $3 a square foot installed and is the cheapest option up front, but it needs regular regrading and refilling.
• Pavers run $10 to $25 a square foot. They cost the most and are the easiest to repair, since a damaged section can be lifted and relaid.

Concrete in the middle lasts a long time when the base is right. Spread 9,920 dollars over 30 years and it is 9,920 / 30 = 330.67 dollars a year. Spread 4,480 dollars of asphalt over 20 years and it is 4,480 / 20 = 224 dollars a year, plus sealcoating along the way. Concrete usually wins on maintenance, asphalt usually wins on the first check you write, and gravel wins if the budget is the only thing that matters.

Every price on this page is a planning range for the United States in 2026. Local labor rates, concrete prices, dump fees and permit rules vary enormously, so treat this as a starting point for conversation and get written bids from licensed local contractors before you sign anything.
