Concrete Slab Cost by State: 20×20 Patio $2,990 to $4,510
A 20×20 concrete patio (4-inch, wire mesh, 4-inch stone base) typically costs $2,990 in Alabama and $4,510 in Hawaii, against $3,360 nationally, when the crew is paid each state’s BLS wages (May 2025, read October 2026). Concrete and materials are priced the same everywhere, so the spread is labour. Find your state below.

Every row is the same slab: 20×20 ft, 4 inches of 3,000 PSI ready-mix, wire mesh, 4-inch crushed-stone base, broom finish, forms, overhead and margin. Only the crew wage changes: half cement masons (47-2051) and half construction laborers (47-2061) at the state’s 25th percentile, median and 75th percentile hourly wages, times the BLS employer-cost burden for construction. The index is the state’s cement-mason median divided by the US median of $27.41. Wages: BLS OEWS May 2025 state file, read 14 October 2026.
Where We Have a State’s Own Ready-Mix Price
Ready-mix plants rarely publish prices. The four that do, and that our model uses, are in four states. Outside them, ask a local plant for its per-yard price, its small-load charge and its delivery charge before you compare quotes.
| Supplier | Where | 3,000 PSI per cu yd | 4,000 PSI per cu yd |
|---|---|---|---|
| Supreme Concrete | Los Angeles, CA | $127.05 | $132.00 |
| Minimix Concrete | Pequannock, NJ | $136.00 | $142.00 |
| Gehring Construction & Ready-Mix | Columbus, NE | $148.00 | $156.00 |
| Scenic City Ready Mix | Tennessee | $165.00 | $175.00 |
Why Your Local Quote Can Differ From Your State Row
- Metro wages. BLS state medians average cities and rural areas together; a crew in a large metro is usually paid more than the state median.
- Distance from the plant. Delivery charges grow with distance. Gehring, in Nebraska, publishes no mileage charge within 20 miles and a per-mile charge beyond it.
- Frost and soil. Cold-climate codes and poor soil can call for a deeper base or thicker slab. Our row assumes a 4-inch base.
- Permits. Fees are set by each city or county. Check yours; our rows include none.
For a quote you already have, the quote checker uses the same state wages at your size and spec.
How We Price a Slab
Every installed price on this site comes from one model: published ready-mix and materials prices, plus crew hours priced at Bureau of Labor Statistics wages, plus overhead and margin. The low figure uses the lowest published input and our lowest assumption at every step; the high figure uses the highest. The crew hours, overage and margin are our own estimates, not published figures, and are listed below so you can check them against your quote. Worked example: a 20 x 20 ft patio (national wages) (4-inch, 3,000 PSI, wire mesh, broom finish, 4-inch stone base).
| Line | Low | Typical | High | Basis |
|---|---|---|---|---|
| Ready-mix concrete | $659 | $754 | $896 | 4.94 cu yd plus 5 to 10% overage, at published per-yard prices |
| Delivery and small-load charges | $0 | $35 | $419 | Per-truck charges from the same price lists (10 yd per truck) |
| Crushed-stone base | $261 | $325 | $443 | 4 in compacted crusher run |
| Reinforcement | $96 | $96 | $96 | 6x6 10-gauge mesh panels, lapped |
| Form lumber | $30 | $45 | $61 | Perimeter boards, shared across reuses |
| Crew labour | $770 | $1,332 | $2,101 | Crew hours x BLS wages x employer costs |
| Overhead and margin | $363 | $776 | $1,606 | 20% to 40% on direct cost |
| Installed total | $2,180 | $3,360 | $5,620 | Rounded to the nearest $10 |
Not included: excavation and soil haul-off, removing an old slab, permits, pumping, decorative finishes and sealing. Totals are national; the calculators’ state option swaps in that state’s BLS wages and leaves concrete and materials at the published lists.
Published inputs (read 13 October 2026)
- Ready-mix, per cubic yard: 3,000 PSI $127.05 to $165.00, 4,000 PSI $132.00 to $175.00, from Supreme Concrete (Los Angeles, CA), Minimix Concrete (Pequannock, NJ), Gehring Construction & Ready-Mix (Columbus, NE, list dated 2026-01-01), Scenic City Ready Mix (Tennessee, list dated 2024-08-03).
- Small orders and trucks: short-load charge $50 under 4 yd (Gehring) or $100 at 5 yd or less, plus $100 more at 2 yd or less (Scenic City); per truck, no charge within 20 miles (Gehring), a $35 surcharge (Scenic City), or $363.88 Zone A delivery plus a $55 environmental fee (Supreme).
- Crushed-stone base: $44.00 to $74.75 per cubic yard from D & L Supply (Central New York, $44.00/yd), JMJ Companies (Lynchburg, VA, $39.50/ton), Golden Landscaping Supply (Cumming, GA, $50.00/ton), Yard Works Landscape Supply (Fort Mill, SC, $74.75/yd); per-ton prices converted at 2,450 lb per yard.
- Steel, forms, poly: #4 rebar 20 ft $8.99, 6x6 10-gauge mesh 4x8 panel $6.99, 2x6x12 $14.32, 2x4x16 $12.13, 6-mil poly 8 ft 4 in x 100 ft $59.99, rebar chair $0.33 (Menards online prices; Home Depot and Lowe’s pages could not be read that day). That works out to $0.24 per sq ft for mesh and $0.74 per sq ft for a rebar grid, materials only.
- Wages: BLS OEWS 47-2051 cement masons (May 2025) 25th percentile $22.60, median $27.41, 75th $32.15 an hour; 47-2061 construction laborers $18.57, $22.66, $28.72. Employer costs from BLS ECEC June 2026, construction industry ($51.96 total compensation per $36.13 of wages, x1.44): a crew hour costs $29.60 to $43.77.
Our assumptions (estimates, not published figures)
- Crew: half cement masons, half laborers.
- Setup per job: 8 to 16 crew hours (layout, stripping, cleanup).
- Per 100 sq ft: 4-inch 4 to 7 crew hours, 6-inch 5 to 8.5, 8-inch 6 to 10; add 0.5 to 1 for mesh or 1.5 to 2.5 for rebar.
- Concrete overage 5% to 10%; base stone ordered at 1.2x its compacted volume; form boards charged at half to all of their price.
- Overhead and margin 20% to 40% of direct cost.
- 6-inch and thicker slabs use 4,000 PSI mix; thinner slabs 3,000 PSI.
