How to Price a Concrete Driveway per Square Foot: The Math

Here is how to price a concrete driveway per square foot so the number holds up on pour day. Measure the slab and apron as separate shapes, turn square feet and thickness into cubic yards, price the concrete delivered, then add base, steel, forms, finish, removal and labor. The per square foot rate is the last line.

Measure the driveway as separate shapes

A driveway is rarely one rectangle. Measure the main slab, the apron at the street and any pad or walk as their own shapes, because each can carry a different thickness and finish. Length times width gives each shape's square feet.

1. 1Step 1: Wheel the main slab: length from the garage slab to the apron, width at the widest point, a second width if it flares.
2. 2Step 2: Measure the apron on its own; many towns require it thicker than the rest.
3. 3Step 3: Note the drop from garage to street. Concrete Network, citing the Portland Cement Association, puts the minimum fall at 1/8 inch per foot away from the house, so a flat lot may need grading.
4. 4Step 4: Photograph the old surface, the soil at the edges and the access from the street; those decide removal, base and the pump.

How many yards of concrete for a driveway

The formula is the one on Concrete Network's calculator page: length times width times thickness, all in feet, gives cubic feet; divide by 27 for cubic yards. Inches become feet when you divide by 12, so a 4 inch slab is 0.333 feet thick.

Never order the exact amount. The same page says to include a margin of safety and gives a budget rule of thumb: add a quarter inch to the slab thickness, so a 4 inch slab goes into the formula at 4.25 inches. A short truck costs a second delivery fee and a cold joint across the drive.

Four inch vs six inch concrete driveway

Concrete Network's driveway essentials say to place concrete at a minimum thickness of 4 inches, and that going to 5 inches adds roughly 20 percent to the concrete cost while raising load capacity by nearly 50 percent, a figure it credits to the Tennessee Concrete Association. Its thickness page says 4 inches is enough for passenger vehicles, a large RV calls for 5 or 6 inches, and many municipalities require a 5 or 6 inch apron. Quote both when the customer parks a truck or trailer.

Base, steel, forms and joints

Concrete Network's thickness page says contractors typically install a well graded, compacted gravel subbase and that local codes commonly call for a 4 inch minimum slab on one. Its essentials guide gives a depth only for expansive soils: 2 to 8 inches of crushed rock. Price the base as tons of stone at your supplier's price plus the hours to spread and compact it.

Rebar or wire mesh for a driveway

The rule in the same guide: wire mesh for driveways 4 to 5 inches thick, rebar for 5 inches or more, bars about 12 inches apart with blocks under the steel to hold it centered. It also says reinforcement will not prevent cracks; it holds them together, which is worth a sentence on the quote. Steel is cheap next to concrete: Ernest Maier, a Maryland building supplier, lists #4 rebar at $0.51 per foot in 20 foot sticks, $10.20 a stick, and Kuhlman Corporation lists a 20 foot #4 grade 60 bar at $14.96. Count the sticks from the grid; price mesh by the roll at your supplier's figure.

Forms are your lumber, stakes and the hours to set and strip them, priced per linear foot of edge. Control joints come at a maximum spacing of 10 feet on a 4 inch slab, one quarter of the thickness deep, with isolation joints at the sidewalk and the garage slab. The American Concrete Institute's FAQ on saw cuts says cuts typically fall within 4 to 12 hours after placing, sooner in hot weather: a return trip on pour day, so put it in the labor hours.

Concrete price per yard, delivery and the short load fee

Your supplier's quote is the number that goes on the estimate. For a published reference, Fixr's concrete delivery survey, a homeowner cost guide updated January 31, 2025, lists $125 to $133 per cubic yard before delivery, a standard 10 cubic yard truck, $55 to $65 delivery per full load, a short load fee of $15 to $17 per cubic yard under a full truck, and a waiting fee averaging $75 an hour when the pour runs long.

Ask the plant for its minimum, its short load fee and any fuel charge, then write the strength on the quote. Bagged mix is for a patch: the same Maryland supplier lists a bag of Quikrete Concrete Mix at $6.95, and a driveway takes hundreds.

Labor by the hour, then the finish

Price the crew in hours before you price the slab in square feet. O*NET, the US Department of Labor's occupation database, reports a median wage of $27.41 an hour for cement masons and concrete finishers, $57,020 a year, from 2025 Bureau of Labor Statistics data. Add payroll taxes, insurance and the truck, then multiply by the hours: removal if there is one, a day for base and forms, the pour and finish, and the return for saw cuts and stripping.

The finish sets the hours and the market band. Concrete Network's guide describes the plain sequence: screed, float before bleed water builds, then a broom for traction. Exposed aggregate adds a retarder and a wash the next morning; stamping adds mats, release and a crew that can keep up with the set. Fixr's driveway survey, updated January 31, 2025, prices plain at $6 to $8 per square foot, broom finished and exposed aggregate at $8 to $12, and stamped at $12 to $18. Concrete Network also says to start curing right after finishing and keep cars off for at least a week; price the compound and put the week in the quote.

Removal, access and the pump

An old slab is its own job. Fixr's survey puts breaking up and hauling away old concrete at $1 to $4 per square foot depending on depth and reinforcement. Dump fees come from your landfill's schedule; Larimer County, Colorado, for example, charges $40 per cubic yard for rubble plus a state surcharge, and broken concrete takes more room in the truck than it did in the ground. If the truck cannot back to the forms, a line pump and operator go on the quote at the pump company's hourly rate and minimum.

Writing the quote and getting paid in stages

Show the arithmetic: one line per shape with its square feet, thickness and finish, then base, steel, removal and the pump as their own lines (writing a service quote customers approve covers the wording). Concrete is bought before it is poured, so ask for a deposit and bill the rest when the slab is down. Check your state's cap: Maryland's home improvement deposit section says a person may not receive a deposit of more than one third of the contract price. How much deposit a contractor should ask for lists other states, and billing a job in stages covers the draw after the pour.

Good to know: This is general information, not legal advice. Deposit caps and contract rules differ by state and change; read the current statute or ask your licensing board before you rely on it.

In MakeHay, a quote carries line items in your own units, so the slab goes in per square foot, the forms per linear foot and the pump as a flat item; the free satellite tool traces the existing drive before the site visit, and a saved measurement fills a quote line. A deposit on the quote is collected when the customer approves and signs online, and the balance can be billed in stages after the pour. Good, better and best, such as 4 inch broom, 5 inch broom and 5 inch exposed aggregate, go out as packages on one quote.

The customer sees each shape, thickness and finish as its own line before approving.
