Concrete Driveway Cost Calculator

Two contractors quoting the same 480 sq ft driveway can land at $3,500 and $7,000 without either one being dishonest. The difference is almost always below the surface — literally. A driveway poured on compacted gravel over undisturbed soil needs minimal prep. A driveway replacing an old cracked slab on expansive clay soil needs demolition ($1-$3/sq ft), grading, and possibly a thicker subbase with geotextile fabric. The concrete itself is the same price in both scenarios.

This calculator separates the five cost layers — concrete, subbase, reinforcement, finish, and labour — so you can see which component drives your specific project. For most standard residential driveways, concrete and labour split the budget roughly 60/40 when you include subbase and reinforcement with materials. The finish type is the optional variable: a broom finish adds nothing to a standard pour, while stamped patterns can add $2,000+ to the same driveway.

Thickness matters more than most homeowners expect. A 4-inch slab handles passenger cars and light trucks (up to about 8,000 lbs gross vehicle weight). If you park an RV, a loaded work truck, or a boat trailer on the driveway, 5-6 inches prevents the stress cracking that sends hairline fractures across thin slabs within a few years. Use the concrete slab weight tool to check the dead load your subgrade needs to support at your chosen thickness.

The three standard driveway finishes serve different budgets and aesthetic goals. All three use the same concrete — the difference is what happens in the 30-60 minutes between pouring and initial set.

Broom finish is the standard for residential driveways. After the concrete is screeded and floated smooth, a stiff-bristled broom is dragged across the surface to create parallel texture lines. This provides traction in rain and snow, costs nothing beyond the base pour, and is the finish most building departments expect when they say "standard concrete driveway." Every municipal sidewalk and most garage floors use broom finish.

Exposed aggregate reveals the stone within the concrete by washing away the surface paste after partial curing. The result is a pebbly, textured surface that provides excellent traction and hides minor stains. The premium ($2-$3/sq ft) covers a surface retarder chemical, pressure washing, and sealing. Exposed aggregate works well in climates with freeze-thaw cycles because the texture prevents the ponding that accelerates surface scaling.

Stamped concrete uses rubber stamps pressed into fresh concrete to replicate the look of brick, slate, flagstone, or tile. After stamping, integral colour or surface-applied stain provides realistic shading. The premium ($3-$6/sq ft) reflects the skilled labour required — stamping is time-sensitive and mistakes cannot be corrected once the concrete begins setting. Stamped driveways need resealing every 2-3 years to maintain colour and protect the stamp pattern from UV and deicing salt damage. For the concrete itself, make sure the mix proportions target 4,000 PSI — stamped surfaces crack more visibly than broom finish if the mix is under-strength.

Every driveway project stacks the same five cost layers. The table below shows typical ranges for each component at March 2026 US national averages. Your local prices vary by region, season, and concrete demand — spring and autumn are peak pouring seasons with higher labour rates in many markets.

Component	Cost Range	Notes
Concrete (4,000 PSI ready-mix)	$155–$170 per cu yd	Delivery fee often included within 10-20 miles of batch plant
Subbase (4 in compacted gravel)	$0.65–$0.85 per sq ft	Includes delivery, spreading, and compaction
Wire mesh (6×6 W1.4)	$0.40–$0.60 per sq ft	Positioned mid-slab on chairs during pour
Rebar grid (#4 @ 18 in o.c.)	$1.00–$1.50 per sq ft	Cut, tied, and chaired on-site; better crack control
Forming and finishing labour	$4.00–$5.00 per sq ft	Includes form setting, pouring, screeding, finishing, curing
Exposed aggregate premium	$2.00–$3.00 per sq ft	Surface retarder + pressure wash + sealer
Stamped finish premium	$3.00–$6.00 per sq ft	Stamps, colour, release agent, sealer, skilled labour
Demolition (if replacing old slab)	$1.00–$3.00 per sq ft	Sawcutting, breaking, hauling — not included in calculator

For driveways over 800 sq ft, most contractors offer volume discounts on labour because the forming-to-pouring ratio improves. A 1,200 sq ft driveway does not cost 2.5 times a 480 sq ft driveway — the forming perimeter grows slower than the area. If your project involves significant excavation, get that quoted separately before the concrete crew arrives.

A well-planned driveway pour avoids the two most expensive problems: a cracked slab from poor subbase prep and a surface that scales from improper finishing or curing.

1. Check local codes and permits. Most jurisdictions require a permit for new driveways or driveway replacements. Common requirements: minimum setback from property lines (typically 3-5 ft), maximum driveway width at the street (often 24 ft), and an approved curb cut. Some HOAs restrict stamped patterns or exposed aggregate colours. Pull the permit before ordering concrete.

2. Prepare the subbase. Remove topsoil and organic material to reach firm, undisturbed soil. Spread 4-6 inches of compacted gravel (crushed limestone or recycled concrete aggregate) as the subbase. Compact in 2-inch lifts with a plate compactor. The subbase distributes the load, provides drainage beneath the slab, and prevents the slab from settling into soft soil. On expansive clay soils, a 6-inch subbase with geotextile fabric separation prevents clay heave from cracking the slab.

3. Set forms and reinforcement. Use 2×4 or 2×6 lumber for edge forms, staked every 3-4 feet and braced plumb. Set forms to maintain a 1-2% slope away from the garage for drainage (1/4 inch per foot). Place wire mesh or rebar on chairs at mid-depth. Plan control joints every 8-12 feet in both directions — concrete cracks, and joints tell it where.

4. Pour and finish. Order 4,000 PSI concrete (standard driveway strength). Start at the far end and work toward the truck. Screed to form height, bull-float to close the surface, then apply the chosen finish. For broom finish, wait until bleed water disappears before brooming. For stamped, timing is critical — stamp when the concrete holds a thumbprint without sticking.

5. Cure for at least 7 days. Apply curing compound or cover with plastic sheeting immediately after finishing. Concrete gains most of its strength in the first week — driving on it before 7 days risks surface damage and reduces long-term durability. The concrete curing time tool adjusts cure schedules for your local temperature and humidity. Keep vehicles off for a full 28 days if temperatures are below 50°F during the cure period.

Pouring 3-inch thickness to save money is the most common driveway failure. A 3-inch slab has roughly half the load capacity of a 4-inch slab (bending strength scales with the square of thickness). A standard sedan weighing 3,500 lbs concentrates that load on four tire patches of roughly 30 square inches each. A 3-inch slab on anything other than perfect subgrade cracks within 1-3 years under normal vehicle loading. The extra inch of concrete costs about $0.50/sq ft — a fraction of the $8-$15/sq ft cost of tearing out and replacing a failed driveway.

Pouring directly on soil without a gravel subbase invites differential settlement. Soil compresses unevenly under load — one section settles 1/4 inch while the adjacent section stays firm, and the slab cracks at the transition. A 4-inch gravel subbase bridges soft spots and distributes point loads over a wider area. It also provides a drainage layer that prevents water from pooling beneath the slab, which is the primary cause of frost heave damage in cold climates.

Using deicing salt on new concrete causes surface scaling — the top layer flakes off in thin sheets, exposing aggregate and creating a rough, pitted surface. New concrete is especially vulnerable in its first winter because it has not yet reached full carbonation depth. Wait at least one full winter before applying salt-based deicers. Use sand for traction instead. After the first year, apply a penetrating silane/siloxane sealer before each winter to protect against salt and freeze-thaw cycling.

Skipping control joints lets the slab decide where to crack — and it always picks the worst spot. Concrete shrinks as it cures, generating tensile stress that exceeds its tensile strength. Control joints are saw-cut or tooled grooves (1/4 of slab depth) that create a weak plane where cracks form invisibly inside the joint. Space them every 8-12 feet in both directions, and always cut a joint where the driveway meets the garage floor or sidewalk.
