| Delivery & haul-away | $100 | $200 | $400 | Jurisdiction dependent |
| Permits & inspections | $0 | $100 | $400 | Local rules may apply |
| Finishes & edging | $50 | $150 | $400 | broom, trowel, edges |
| Estimated total | $1,400 | $2,850 | $6,350 | Range accounts for thickness, finish, and extras |
Overview Of Costs
Typical cost range for a 10×20 concrete slab totals $1,400-$6,350. The lower end reflects a basic, unreinforced slab with standard finishes, while the high end includes full subgrade prep, reinforcement, and premium finishes. Assumptions include standard 4″ thickness and a typical suburban site. Per-square-foot estimates often range from $7-$32 when including all components.
Cost Breakdown
Costs are broken down into major categories to show where money goes. The table above aggregates materials, labor, equipment, permits, delivery, and extras to provide a complete picture. Subgrade quality and access drive a large portion of the budget.
What Drives Price
Key price drivers for a 10×20 slab include thickness, reinforcement, subgrade conditions, and finish quality. Thicker slabs and reinforced designs significantly raise material and labor costs. Regional labor rates and permit requirements also influence the final price.
Ways To Save
Strategies to reduce cost include selecting a standard 4″ thickness, using basic wire mesh instead of solid rebar, and batching with a local supplier to reduce delivery fees. Scheduling during off-peak times can lower contractor rates.
Regional Price Differences
Prices vary by region due to labor markets and material transport. In general, urban areas may see higher labor costs, while rural areas can have lower delivery fees. Expect a ±15-25% delta between city and rural projects.
Labor, Hours & Rates
Labor for a typical 10×20 slab includes form setup, pouring, finishing, and curing. Typical crews run 2-4 workers for 4-8 hours, with local hourly rates ranging from $60-$110 per hour per crew. Labor efficiency and weather impact final timing and cost.
Additional & Hidden Costs
Hidden items may include asphalt or soil stabilization, drainage considerations, and temporary utilities. Perimeter edges, expansion joints, and curing compounds can add $100-$400. Don’t overlook permit fees or disposal charges when estimating.
