60x80 Concrete Slab Cost
For a large 4,800-square-foot footprint, a 60x80 concrete slab needs about 97.78 cubic yardsEstimated at 6 inches with 10% added. Its modeled 2026 national installed range is $36,720–$73,440Estimated.
Installed estimate uses HomeGuide's $6–$12/sq ft national range, February 3, 2026. Quantity uses the dimensions and allowance shown.

How to use this 60x80 calculator
01
Keep or change the footprint
The starting footprint is 60 ft by 80 ft, or 4,800 sq ftEstimated. Either dimension can be changed for a different building plan.
02
Compare thickness
The default 6-inch case is a foundation-budget scenario. Use 4, 5, 6, or 8 inches to see how a large pour responds; a project engineer determines the actual specification.
03
Set the allowance
The preset 10% is applied to volume and bag quantity after the rectangular slab is measured. It does not increase the square footage used for installed pricing.
04
Select the metro
Dallas, Chicago, Seattle, and Atlanta use the same BLS wage adjustment as the other size pages. Keep national when no listed metro is a useful comparison.
60x80 slab calculation formula
The footprint first becomes cubic feet, then yards and bags. Material and installed totals use separate sourced unit prices.
Cubic yards and bags

Concrete slab prices by size
Each row uses a 4-inch slab and the same 10% quantity allowance, so the 60x80 footprint can be compared directly with the four smaller published sizes.

60x80 thickness and reinforcement scenarios by use
At 4,800 square feet, a one-inch thickness change moves a substantial amount of concrete. These are planning comparisons rather than structural instructions.
| Use | Budgeting thickness | Reinforcement allowance | Concrete-only installed model |
|---|---|---|---|
| Metal building, garage, or workshop foundation | 6 in Estimated | Rebar priced separately | $36,720–$73,440 Estimated |
| Large carport or agricultural building | 5 in Estimated | Project-specific | $32,760–$65,520 Estimated |
| Commercial or warehouse floor | 6 in or more Estimated | Rebar priced separately | $36,720–$73,440 at 6 in Estimated |
HomeGuide lists 6 inches for a foundationVerified and says foundations typically use steel rebar, dated February 3, 2026. That supports the page's default estimating category; an engineer and local requirements still determine thickness, reinforcement, and joints.
Concrete quantity and material cost by thickness

Extra costs on a large 60x80 slab
A nearly 100-cubic-yard default pour can add access, sequencing, and reinforcement line items. Unit prices remain separate so they are not counted twice when already included in a bid.
Expansion-joint material
$0.50–$2/LF VerifiedMaterial-only range from HomeGuide, April 3, 2026. Total linear feet depend on the quote's joint layout, so this page does not invent a project total.
Phased-pour deliveries
$55–$65/load VerifiedHomeGuide full-load delivery fee, accessed October 7, 2026. Each additional scheduled load adds that published delivery unit; separate mobilization, joint, and crew costs require quote-specific line items.
Concrete pump
$150–$300/hr VerifiedHomeGuide, accessed October 7, 2026, reports a typical 2–4 hour minimumVerified. Pumping can therefore appear separately from the ready-mix and installed-slab totals.
Rebar upgrade

Also compare base preparation at $1–$3/sq ftVerified, HomeGuide, February 3, 2026—equivalent to $4,800–$14,400Estimated across this footprint. These add-ons may overlap an installed quote, so they should not be blindly added twice.
60x80 slab cost by metro area
The 6-inch model holds the 4,800-square-foot footprint constant and changes only the labor share with BLS May 2025 construction and extraction wages.

|---|---|---|---|---|
| Dallas concrete cost | $27.03/hr Verified | $7.27–$14.55 Estimated | $34,900–$69,820 Estimated | BLS May 2025 model |
| Chicago concrete cost | $40.87/hr Verified | $8.46–$16.92 Estimated | $40,620–$81,240 Estimated | BLS May 2025 model |

What is a 60x80 foundation used for?
A 60x80 footprint contains 4,800 sq ftEstimated. Published building examples position that floor area for multi-bay, agricultural, and light-commercial work.
Multi-bay garage or workshop
Four 20-ft bays VerifiedUniversal Steel says an 80-foot-long building can divide into four 20-foot bays for vehicle, repair, or fabrication work; checked October 7, 2026. Door placement and working clearance still depend on the design.
Metal-building foundation
$36,720–$73,440 EstimatedThe concrete-only 6-inch scenario uses HomeGuide's February 3, 2026 installed benchmark and the disclosed thickness model. It excludes the building shell, engineering, reinforcement, and pumping unless a quote explicitly includes them.
Carport or farm building
4,800 sq ft EstimatedSteel Structures America identifies 60x80 buildings with large equipment storage and farm operations; checked October 7, 2026. The calculator measures concrete, not agricultural layout or structural capacity.
Commercial warehouse floor

DIY material baseline vs. installed price
For this 4,800-square-foot footprint, “DIY” below means ready-mix material only. It is not equivalent to a complete self-performed foundation budget or to an installed contractor scope.
DIY: ready-mix material only
$11,730–$15,640 EstimatedCalculated as 97.78 yd³Estimated multiplied by HomeGuide's $120–$160/yd³Verified, April 3, 2026. Forms, base, reinforcement, equipment, delivery modifiers, finishing, and labor remain outside this card.
Contractor: installed benchmark
$36,720–$73,440 EstimatedThe 4,800 sq ftEstimated footprint uses HomeGuide's $6–$12/sq ft installedVerified national range dated February 3, 2026 and the same 6-inch thickness model used by the calculator.
Modeled difference: $21,080–$61,710Estimated. This subtracts the material-only range from opposite ends of the installed range; it is not a complete DIY budget or promised saving.
What the quantity says: the default scenario represents 97.78 yd³, 4,400 bags, and about 369,600 lbAll estimated. HomeGuide describes full loads as 10 yd³Verified, accessed October 7, 2026, so the volume is approximately 9.78 full truckloadsEstimated.
60x80 concrete slab cost FAQ
How many cubic yards are needed for a 60x80 concrete slab?
A 60x80 slab at 6 inches needs about 97.78 cubic yards with 10% addedEstimated. The 4-, 5-, and 8-inch cases require 65.19, 81.48, and 130.37 yd³Estimated, respectively.
How much does a 60x80 concrete slab cost in 2026?
The 6-inch national installed model is $36,720–$73,440 in 2026Estimated. The separate 4-inch size-table baseline is $28,800–$57,600Estimated; both start with HomeGuide's verified February 3, 2026 rate.
How thick should a 60x80 metal-building foundation be?
This calculator defaults to a 6-inch reinforced-foundation budgeting scenario. HomeGuide lists 6 inches for a foundationVerified and says foundations typically use steel rebar, February 3, 2026. That supports the estimate category, not a project-specific structural specification.
Does a concrete pump cost extra?
It often appears as a separate line item. HomeGuide reports $150–$300 per hourVerified with a typical 2–4 hour minimumVerified; source accessed October 7, 2026. The exact charge depends on the quoted equipment and time.
Can a 60x80 slab be poured in two phases?
Two phases should be priced as separate scheduling and delivery scopes. HomeGuide lists full-load delivery at $55–$65 per loadVerified; source accessed October 7, 2026. The calculator can quantify each phase's volume, but project documents determine joints and structural details.
How do I tell whether a 60x80 quote is reasonable?
Divide the quote total by 4,800 sq ft and compare that rate with the selected metro estimate. Then identify whether base preparation, reinforcement, expansion joints, deliveries, pumping, and finishing are included or separately priced.
