A ready mix concrete calculator estimates how many cubic yards a project needs; the calculator itself is usually free. U.S. buyers typically pay $125-$180 per cubic yard for standard ready-mix concrete, with delivery, short-load fees, site access, and labor affecting the total.

| Concrete per cubic yard | $125 | $150 | $180 | Standard mix, before special fees. |
| Small residential delivery | $500 | $1,200 | $2,500 | Varies with volume, labor, and access. |
| Installed slab | $6 | $10 | $18 | Per sq ft for typical residential work. |
Ready-mix concrete prices for common residential pours
Ready-mix is priced by the cubic yard, but the delivered total also reflects minimum loads and local supplier charges. A full truckload of 8-10 cubic yards may cost about $1,000-$1,800 for concrete and standard delivery, before placing and finishing labor. Smaller orders can cost substantially more per yard.
For an installed, basic 4-inch patio or walkway, a typical budget is $6-$12 per square foot. Reinforcement, excavation, forms, decorative finishes, or difficult access can raise that to $12-$18 or more per square foot. Assumptions: standard 3,000-4,000 PSI mix, normal access, and average U.S. labor rates. Use the calculator’s volume as a starting point, then add roughly 5%-10% for spillage and uneven subgrade.
What concrete, crew, and delivery add to the quote
Concrete supply is only one part of a poured-slab estimate. The table shows common residential ranges; actual charges depend on location, order size, and how much work the contractor includes.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Ready-mix concrete | $125-$180 per cubic yard | Strength, additives, local plant rates. |
| Labor | $50-$100 per worker-hour | Crew size, finishing detail, site conditions. |
| Forms and reinforcement | $1-$4 per sq ft | Lumber, wire mesh, rebar, project shape. |
| Delivery and short-load fees | $50-$300 or more | Distance, minimum load, dispatch policy. |
| Pump or wheelbarrow placement | $150-$900 | Truck reach, access, pour volume. |
Labor is usually estimated from crew hours multiplied by the local hourly rate, plus equipment and preparation. Site preparation, removal of old concrete, and disposal may be quoted separately rather than included in a per-square-foot price.
How slab thickness and order size change calculator results
Concrete volume can be estimated with this formula: square feet × thickness in inches ÷ 324 = cubic yards. A 400-square-foot slab at 4 inches thick needs about 4.94 cubic yards before waste; ordering around 5.2-5.4 yards allows a modest buffer.
Thickness is a major cost driver: increasing a 400-square-foot slab from 4 to 6 inches raises calculated volume from about 4.94 to 7.41 cubic yards, adding roughly $310-$445 at common material rates. Mix strength also matters. A standard 3,000-4,000 PSI mix is common for residential flatwork; higher-strength mixes or air-entrained concrete for freeze-thaw exposure may add about $5-$20 per yard.
Order size can affect the effective price as much as the mix. A supplier may charge a short-load fee of $50-$300 or more when an order falls below its minimum, often around 3-5 cubic yards. Confirm the supplier’s minimum and fee before relying on a calculator’s material total.
Save money by controlling the pour and finish specifications
Accurate measurements reduce overordering, but leaving no waste allowance can lead to an expensive second delivery. Check slab dimensions, thickness, and grade in several spots, then ask the supplier whether its minimum order or short-load charge changes the best quantity to buy.
Compare at least three written estimates using the same square footage, depth, concrete strength, reinforcement, finish, and removal scope. Basic broom finishing generally costs less than stamped or colored concrete, which can add several dollars per square foot. Keep the specification consistent so a lower quote is not simply omitting preparation or finishing work.
Why concrete delivery rates vary by U.S. region
Prices differ with aggregate supply, fuel, labor, and demand. As a broad budgeting adjustment, rural or lower-cost markets may run 5%-15% below national averages, while major coastal metros and high-cost cities can run 10%-30% higher. These are planning ranges, not guaranteed regional quotes.
Remote sites may face extra mileage or limited plant availability, while urban work can incur traffic, parking, and timed-delivery charges. Ask whether the quote includes environmental or fuel surcharges, sales tax where applicable, and waiting time if the crew is not ready when the truck arrives.
Three sample pours show how totals build up
A 10-by-10-foot, 4-inch walkway uses about 1.23 cubic yards before waste. With a short-load charge and simple hand placement, a supply-only order could total $250-$550; a contractor-installed basic walkway may be about $700-$1,400.
A 400-square-foot patio at 4 inches takes about 5.2-5.4 yards with waste. At $130-$175 per yard, concrete is roughly $675-$945; forms, reinforcement, preparation, and finishing can bring an installed quote to about $2,400-$4,800.
A 600-square-foot driveway at 6 inches needs about 11.1 cubic yards before waste, or roughly 11.7-12.2 yards to order. Material may cost $1,520-$2,200; with grading, reinforcement, and finishing, a typical installed range is about $5,400-$10,800. These examples assume straightforward access and do not include major excavation or old-slab removal.
Delivery time, pump charges, and cleanup to price separately
A small crew may spend 4-8 hours on a simple residential slab, while larger or detailed pours can take a full day or longer. The concrete truck may allow only a limited unloading window; delays can trigger waiting charges, so forms, base, and workers should be ready before dispatch.
A pump is useful when trucks cannot reach the pour, but rental and setup can add $150-$900 or more depending on reach and duration. Ask about washout cleanup, overage handling, and disposal of leftover concrete. Get each fee listed separately rather than assuming delivery includes placement and cleanup.
Questions to ask before accepting a ready-mix estimate
Confirm the quoted price per yard, mix strength, included delivery distance, minimum load, and short-load fee. Ask whether taxes, fuel charges, additives, and waiting time are included, and whether the supplier can refund or credit unused material.
For a contractor quote, verify whether excavation, compacted base, forms, reinforcement, placement, finishing, and curing are included. A low price that excludes site preparation may not be comparable to a complete installed estimate. Match the quoted scope to the calculator quantity before comparing totals.
