Concrete Driveway Cost Calculator
Estimate concrete driveway cost from size, slab thickness, and your local concrete price.
Shows cubic yards, a 10% waste cushion, and an installed total.
A concrete driveway is priced on two things stacked together: the volume of concrete that fills the slab, and the labor to form, pour, and finish it. This calculator handles the volume math exactly and leaves the prices to you, because concrete and labor rates swing a lot by region and by year.
Start with the slab. Multiply the length by the width to get the area in square feet, then multiply by the thickness in feet to get cubic feet, and divide by 27 to reach cubic yards. Cubic yards are how every ready-mix plant quotes and sells concrete. A typical residential driveway slab is 4 inches thick. Bump it to 5 or 6 inches if trucks, recreational vehicles, or heavy delivery vans will park on it, since the extra inch is cheap insurance against cracking.
The price side is yours to fill in. Enter the delivered concrete price per cubic yard from a local quote, and the tool multiplies it by the volume after adding a 10 percent cushion for spillage, uneven subgrade, and short loads. If you also enter a finishing cost per square foot, you get a fuller installed estimate, not just the raw material.
Two things this number leaves out unless you add them: a compacted gravel base, which most good driveways need under the slab, and steel reinforcement, either rebar or welded wire mesh. Both add cost and both extend the life of the slab. Treat this figure as the number to sanity-check a contractor quote against, not a replacement for one.
