Concrete Slab Cost in New York
Quick answer: a 4-inch concrete slab in New York costs about $8.00 – $14.50 per sq ft installed, 20% above the U.S. average. A 12 × 12 ft patio runs about $1,290 – $2,230, a 24 × 24 ft garage floor $4,940 – $8,630 and a 20 × 40 ft driveway $6,790 – $11,890.
New York has two price levels. Statewide our model puts concrete well above the national average, and the New York City metro higher still, among the most expensive places in the country to pour a slab. Upstate, the bigger factor is winter: freeze-thaw cycles and road salt decide how long a slab lasts.

4-inch slabs unless shown. Installed: forms, broom finish and labor, up to vapor barrier, #4 rebar and contractor overhead and profit. DIY: concrete (ready-mix or 80-lb bags, whichever is cheaper) and forms, up to vapor barrier and rebar. Excavation, gravel base and permits are extra.
Metro Areas
Prices in the biggest metro areas differ from the state as a whole, mainly because of labor costs.
| Area | Factor | Slab per sq ft | 12 × 12 patio | 24 × 24 garage | 20 × 40 driveway |
|---|---|---|---|---|---|
| New York (statewide) | 1.20 | $8.00 – $14.50 | $1,290 – $2,230 | $4,940 – $8,630 | $6,790 – $11,890 |
| New York City metro, NY | 1.35 | $8.50 – $16.00 | $1,410 – $2,420 | $5,460 – $9,440 | $7,510 – $13,020 |
Building a Slab in New York
| Weathering (IRC) | Severe statewide. |
|---|---|
| Concrete strength | 4,000 PSI air-entrained (5-7% air) for driveways and anything that sees de-icing salt; 3,500 PSI air-entrained is the code minimum for outdoor slabs and garage floors. 4,000 PSI ready-mix runs about $172 – $216 per yd³ here. |
| Frost depth | Usually 36 to 48 in; most of upstate uses 42 to 48 in. Your town's code sets the exact depth. |
| Soil | Glacial till with stones, rock close to the surface in many areas, and clay in some valleys. Rock removal can add a lot to excavation. |
| Pouring season | May to October. Late-fall pours need hot water in the mix, insulated blankets and time to gain strength before the first hard freeze. |
- In New York City, work on the public sidewalk or a driveway curb cut needs city permits, which add cost and lead time; a backyard patio usually does not.
- Keep de-icing salt off new concrete for its first winter, and seal outdoor slabs once they have cured.
- Slabs on rocky upstate lots may need a breaker or a thicker gravel base to level out; get the excavation priced separately.
Frost depths and permit rules are set by your city or county; check with the local building department before you dig. A permit for a small residential slab or driveway typically costs about $50 – $350.

Picking a location sets the ready-mix, excavation and labor rates below to that area's typical level. You can still type your own local prices afterwards. Slab prices by state.
Closer spacing uses more steel and raises the rebar cost.
Not charged when bagged concrete is selected.
A scaled plan of your slab: rebar grid at the spacing you chose, support chairs about every 3 to 4 ft, and the recommended control-joint saw cuts (2.5 times the thickness in inches, in feet, capped at 15 ft). It redraws as you change the inputs.
| Scope Item / Material Description | Amount |
|---|
Enter the total your contractor quoted. We compare it with a benchmark for the same slab and scope you set in the calculator: materials at your entered prices plus labor at the regional standard rate, before any overhead or profit. Make sure the calculator scope (base, rebar, finish, pump, demolition) matches what the bid includes.
Optional: enter the bid's line items to see where the markup sits
Enter the forecast for pour day. The check follows ACI 306R (cold weather) and ACI 305R (hot weather) and estimates the surface evaporation rate that drives plastic shrinkage cracking.
How These Prices Are Worked Out
These are modelled prices, not quotes collected from New York contractors. Each project is priced with the same line items as the slab cost calculator at national unit prices, then New York's location factor of 1.20 is applied to ready-mix concrete and labor, as the calculator does when you pick New York. Bagged concrete, forms, rebar and the delivery fee stay at national prices. The factors are approximate, set by our editors to reflect typical construction cost differences between states; the full method is in the 2026 concrete price report.

About $8.00 to $14.50 per sq ft installed for a 4-inch slab with forms, a broom finish and labor, 20% above the national average. A 12 x 12 ft patio runs about $1,290 to $2,230 and a 24 x 24 ft garage floor (5 in) about $4,940 to $8,630. Excavation, gravel and permits are extra.
A 20 x 40 ft driveway, 5 inches thick with rebar and a broom finish, costs about $6,790 to $11,890 installed in New York ($8.00 to $15.00 per sq ft). Removing an old driveway and the street apron are extra.
About $162 to $192 per cubic yard for 3,000 PSI ready-mix before delivery fees, and about $172 to $216 for 4,000 PSI. Small loads add a short-load fee of $80 to $200 or more.
In the New York City area our model puts 3,000 PSI ready-mix at about $182 to $216 per cubic yard before delivery, and a 4-inch slab at about $8.50 to $16.00 per sq ft installed, 35% above the U.S. average. A 12 x 12 ft patio runs about $1,410 to $2,420 and a 20 x 40 ft driveway about $7,510 to $13,020.
4,000 PSI air-entrained concrete, with about 5-7% air, because New York driveways see both freeze-thaw cycles and de-icing salt. 3,500 PSI air-entrained is the building code minimum for exposed slabs in severe weathering areas.
