What Is This Calculator Used For?
This tool estimates the cost of ready-mix concrete for any poured slab project — driveways, patios, foundations, sidewalks, parking lots, and warehouse floors. It converts your slab dimensions into cubic yards, applies your specified waste factor, and calculates material cost at your local batch-plant price.
Ready-mix concrete (also called transit-mix or truck-mix) is concrete batched at a central plant and delivered by drum truck in its mixed state. It's the standard material for virtually all residential and commercial concrete pours in the United States. Unlike site-mixed concrete, the mix design is precisely controlled at the plant and tested to meet PSI specifications before it leaves the drum.
Use this calculator before meeting with a contractor or calling a batch plant so you arrive with an accurate quantity figure and a realistic budget range. It does not include labor, forming, rebar, or finishing — those are separate line items in a contractor quote.
How to Use This Calculator
- 1
Select your slab type
Choose from Driveway, Patio, Foundation Slab, Sidewalk, Parking Lot, or Warehouse Floor. Each preset fills in the industry-standard thickness. Select Custom to enter any thickness manually.
- 2
Enter your dimensions
Enter the length and width of your slab in feet. For irregular shapes, break the area into rectangles, run the calculator separately for each, and add the results. Adjust the thickness (in inches) to match your spec — 4" is standard residential, 6" for vehicle loads.
- 3
Enter your local concrete price
Call your nearest batch plant for a current price per cubic yard. In Lakeland, FL, expect $130–$160/yd³ in 2025. If you don't have a quote yet, the $145 default is a reasonable Central Florida estimate.
- 4
Set your waste factor
Leave at 10% for standard rectangular pours. Increase to 12–15% for curved or irregular forms or uneven subgrades. The calculator rounds your order up to the nearest quarter yard automatically.
- 5
Add delivery and short-load fees
If your order is under 5 yd³, the short-load fee is automatically included in the total. Add any pump truck fee if you can't access the pour location by chute. These are fixed fees — they don't scale with volume.
Example Calculation
A homeowner in Lakeland, FL wants to pour a new two-car driveway that is 20 feet wide by 40 feet long at 4 inches thick. The local batch plant quotes $148/yd³. Here's how the math works:
| Step | Calculation | Result |
|---|---|---|
| Cubic feet | 20 ft × 40 ft × (4 in ÷ 12) | 266.7 ft³ |
| Raw cubic yards | 266.7 ÷ 27 | 9.88 yd³ |
| Add 10% waste | 9.88 × 1.10 | 10.87 yd³ |
| Round to nearest ¼ yd | — | 11.00 yd³ |
| Material cost | 11.00 × $148 | $1,628 |
| Short-load fee | 11 yd³ ≥ 5 yd³ — not applied | $0 |
| Estimated total | — | $1,628 |
This covers concrete material only. Total installed cost for this driveway (labor, forming, rebar, finishing, sealer) would typically run $4,800–$8,800 in Lakeland at $6–$11/sq ft for labor and materials combined, with concrete representing roughly 20–30% of the total project cost.
Tips for Ordering Ready-Mix Concrete
Always order slightly more
Running short mid-pour is one of the most expensive mistakes in concrete work. A second truck dispatch incurs full delivery charges. The 10% waste buffer in this calculator is a minimum — for complex pours, use 12–15%.
Confirm your mix design before ordering
Specify PSI strength (3,000 for patios, 3,500–4,000 for driveways and structural), slump (4–5" for most residential pours), and any additives — fiber, accelerators, water reducers — before the truck leaves the plant.
Know your truck turnaround time
Ready-mix has a finite workability window — typically 90 minutes from the time water contacts cement. Have all forms set, rebar in place, and your crew ready before the truck arrives. A delayed truck waiting on your site may charge standby time ($50–$100/hr).
Schedule around Florida weather
Pour in the early morning in summer to avoid afternoon thunderstorms and peak heat. Concrete placed above 90°F sets faster and is harder to finish. Most experienced Florida contractors start pours at 6–7 AM in summer months.
Ask about fiber reinforcement
Polypropylene or steel fiber added at the plant ($8–$20/yd³) reduces plastic shrinkage cracking and can sometimes replace wire mesh. It's a common upgrade on Florida residential pours where controlling early cracking is important.
Get the batch ticket at delivery
The batch ticket is your proof of mix design — it lists water/cement ratio, admixtures, load size, and batch time. Keep it for your records, especially on permitted work where inspectors may request documentation.
Factors Driving Ready-Mix Concrete Pricing in 2025
Concrete pricing isn't uniform — it shifts with commodity markets, regional supply, and project specifications. Understanding what drives the number helps you evaluate quotes intelligently.
Cement costs
Portland cement (roughly 15% of concrete by weight) is the primary commodity driver. Cement prices are tied to energy costs at kilns and import/export dynamics. Florida imports significant cement, making it sensitive to logistics costs.
Diesel / fuel surcharges
Every ready-mix batch plant in Florida adds a fuel surcharge that tracks diesel prices. When diesel spikes, expect a corresponding per-yard surcharge of $3–$12. Ask your plant to separate this from the base price.
Aggregate supply
Sand and gravel prices vary by region. Central Florida's geology means most aggregate is trucked or railed in from quarries in other counties, adding transportation cost to every yard.
Mix design and admixtures
Higher PSI mixes use more cement per yard — a 5,000 PSI mix costs $15–$30/yd³ more than a standard 3,000 PSI mix. Admixtures like water reducers, accelerators, set retarders, and fiber reinforcement each add $5–$25/yd³.
Delivery distance
Most plants include delivery within 10–15 miles in the base price. Beyond that, expect a per-mile surcharge of $2–$5/mile each way. Rural Polk County projects may incur significant distance charges.
Market demand
During construction booms, plants run at full capacity and prices firm. During slower periods, you can sometimes negotiate. Q1 (January–March) is typically the most competitive season in Florida.
Itemizing Your Concrete Delivery Costs
A concrete invoice from a ready-mix plant typically includes several line items beyond the base per-yard price. Here's what to look for and typical ranges for Central Florida in 2025:
| Line Item | Typical Range (FL, 2025) | Notes |
|---|---|---|
| Base concrete price | $125–$175 / yd³ | Varies by mix design and plant |
| Fuel surcharge | $5–$15 / yd³ | Tracks diesel index |
| Short-load fee | $50–$150 flat | Applied if order < 5–7 yd³ |
| Delivery / mileage | $2–$5 / mile over zone | Varies by plant's free-zone radius |
| Saturday / after-hours | $50–$200 flat | Not all plants offer weekend delivery |
| Pump truck (separate contractor) | $400–$900 flat | Plus per-yard placement fee |
| Fiber reinforcement | $8–$20 / yd³ | Polypropylene or steel micro-fiber |
| Accelerator (cold-weather set) | $10–$20 / yd³ | Rarely needed in FL |
| Set retarder (hot-weather) | $8–$15 / yd³ | Common in FL summer pours |
| Standby / waiting time | $50–$100 / hr | After ~5–10 min grace period |
Estimating Concrete for a New Patio
Patios are one of the most common residential ready-mix applications. Here are pre-calculated estimates for common patio sizes at standard 4-inch thickness, using $145/yd³ with a 10% waste factor. These are material costs only.
| Patio Size | Sq Ft | Cubic Yards (with 10% waste) | Material Cost Est. |
|---|---|---|---|
| 10 × 10 ft | 100 sq ft | 1.5 yd³ | $218 + short-load fee |
| 12 × 16 ft | 192 sq ft | 2.75 yd³ | $399 + short-load fee |
| 16 × 20 ft | 320 sq ft | 4.5 yd³ | $653 + short-load fee |
| 20 × 20 ft | 400 sq ft | 5.75 yd³ | $834 |
| 20 × 30 ft | 600 sq ft | 8.5 yd³ | $1,233 |
| 24 × 36 ft | 864 sq ft | 12.25 yd³ | $1,776 |
Orders under 5 yd³ will incur a short-load fee from most plants. For the 10×10 through 16×20 sizes above, factor in $75–$150 for short-load. Use the calculator above to adjust for your exact local price and current fuel surcharges.
Key Standards for Concrete Mixes and Delivery
Ready-mix concrete in the United States is governed by two primary standards that define what you're buying and how it must be delivered.
ASTM C94 — Standard Specification for Ready-Mixed Concrete
ASTM C94 governs mix proportioning, discharge requirements, testing, and delivery of ready-mix concrete. Key provisions relevant to homeowners: concrete must be discharged within 90 minutes of mixing or before 300 drum revolutions, whichever comes first. Slump must be tested at delivery if requested. The batch ticket provided by the driver must show mix design, load size, and batch time.
ACI 301 — Specifications for Structural Concrete
ACI 301 is the American Concrete Institute's specification used by engineers and contractors for structural concrete work. It defines strength requirements, water/cement ratios, admissible admixtures, and testing frequency. Residential work typically references simpler building code requirements (Florida Building Code Section 1905), which align with ACI 318 for structural elements.
NRMCA — National Ready Mixed Concrete Association
The NRMCA publishes pricing and production data quarterly. Their Concrete in Practice (CIP) sheets are free resources covering common concrete topics — slump, air entrainment, hot weather, and cold weather concreting. The NRMCA also certifies ready-mix plants under their Plant Certification Program, which verifies batch equipment calibration and quality systems.
Florida Building Code — Concrete Requirements
Florida's Building Code (based on IBC) requires a minimum 3,000 PSI for most residential structural concrete and 3,500 PSI in high-velocity hurricane zones. For non-structural flatwork (driveways, patios, sidewalks), no minimum PSI is mandated by the FBC, but contractors commonly use 3,000–3,500 PSI for durability in Florida's climate.
Industry Benchmarks for Concrete Pricing
Use these national and regional benchmarks to evaluate quotes. Regional variation is significant — Florida prices run 5–15% above national averages due to import dependence and hurricane demand cycles.

Ready Mix Concrete Cost FAQ
How much does ready-mix concrete cost per cubic yard in Florida in 2025?+
Ready-mix concrete in Florida ranges from $125 to $175 per cubic yard in 2025, with a regional average near $145/yd³. Polk County plants (serving Lakeland, Bartow, and Winter Haven) run $130–$160/yd³ depending on mix design, fiber additives, and delivery distance. Prices fluctuate with diesel and cement commodity costs.
What is a cubic yard of concrete and how much does it cover?+
One cubic yard of concrete is 27 cubic feet (3 ft × 3 ft × 3 ft). At 4 inches thick, one cubic yard covers 81 square feet. At 6 inches thick it covers 54 square feet. Use the calculator above to convert your exact dimensions — most batch plants sell in 0.25-yard increments.
What is a short-load fee and when does it apply?+
A short-load fee is a surcharge charged by ready-mix plants when your order falls below their minimum profitable load — typically 5 to 7 cubic yards. The fee ($50–$150) compensates the plant for dispatching a truck that isn't loaded to capacity. Small patios, walkways, and steps almost always trigger a short-load charge. Batching your own concrete with bags is sometimes cheaper for orders under 1 yard.
What waste factor should I use for my concrete estimate?+
Use a 10% waste factor for standard rectangular slabs with straight forms. Increase to 12–15% for curved forms, complex shapes, or sites with uneven subgrades. Decrease to 7–8% only for simple, level pours where your formwork is precise and verified. Ordering short on concrete — requiring a second truck dispatch — costs far more than the 10% buffer.
What PSI concrete mix should I order for a residential driveway?+
Residential driveways in Florida should use a minimum 3,000 PSI mix (ASTM C94 standard). Many contractors specify 3,500 PSI for driveways subject to vehicle traffic in Florida's heat and moisture cycles. Patios can use 3,000 PSI. Foundations and structural elements typically require 4,000 PSI or higher per local code. Always confirm the specified PSI with your contractor before ordering.
Does the calculator include labor and installation costs?+
No — this calculator covers material costs only (concrete + short-load + optional delivery/pump fees). Total installed cost for a poured concrete project also includes excavation, grading, forming materials, rebar or wire mesh, finishing labor, curing compound, and sealer. In Lakeland, FL, installed concrete runs $8–$18/sq ft for driveways and patios — see our cost guides for full project estimates.
When should I rent a concrete pump vs. use chute delivery?+
Use a pump when the pour location is more than 18–20 feet from where the truck can park, when elevation changes make chute delivery impractical, or when you're pouring a large area and need faster placement to avoid cold joints. Pump rental typically adds $400–$900 to the job. Chute delivery is free and works fine for most residential driveways and patios with good truck access.
