2026 Planning Tool for the Bluegrass State
Estimate concrete cost in North Carolina for slabs, patios, driveways, garage floors and ready-mix orders. Enter your own local dimensions, concrete price, labor rate, delivery charges and project extras so the estimate reflects your North Carolina supplier or contractor quote instead of relying on one statewide average.
Choose a project type, enter your measurements and adjust every cost input to match your supplier or contractor.
Estimate concrete yardage and a planning budget for a rectangular slab. Tax is applied only to the ready-mix material line in this estimator.
Replace with your North Carolina supplier quote.
North Carolina total rates vary by county; 7.00% is a sample input. Replace it with the rate for the project location and transaction.
Build a driveway estimate with concrete, labor, base preparation, reinforcement, finish upgrades and optional demolition.
Estimate a delivered ready-mix order from the number of cubic yards and your supplier's quoted fees.
Use supplier's fee if the order is below its minimum.
Multiply project area by your own low and high installed price per square foot. The default range is a national planning reference, not a North Carolina quote.
The answer depends on whether you mean the price of ready-mix concrete per cubic yard or the total installed price of a finished slab, patio, driveway or foundation component. Those are very different numbers. Ready-mix is only one line in the budget. A contractor may also price excavation, compacted stone base, forming, reinforcement, placement labor, finishing, joints, curing, mobilization, demolition and cleanup.
For 2026 planning, national concrete pricing guides place ready-mix broadly around the mid-$100s per cubic yard, while installed slab pricing is often discussed on a per-square-foot basis. Concrete Network lists about $6.50 to $10.50 per square foot for a plain poured slab as a national installed planning guide. Ready-mix prices vary substantially by supplier, haul distance, load size, strength and admixtures, so the per-yard field remains fully editable. Those numbers are useful as a benchmark, but they are not a statewide North Carolina price list. Your actual North Carolina bid can land below or above those references depending on supplier distance, order size, project access and finish.
The calculator above therefore starts with editable planning inputs. Replace the sample $175-per-yard ready-mix value with a current quote from a North Carolina producer serving the project address. Replace the labor, base-prep and reinforcement values with contractor numbers from your city or county. This approach is much more useful than treating a single statewide average as a guaranteed price.

Use this table as a budgeting worksheet rather than a quote. The ready-mix and installed ranges are national reference points, while current North Carolina sales and use tax rates come from the North Carolina Department of Revenue. Supplier charges and contractor pricing remain local.
| Cost Item | Planning Reference | How to Use It in North Carolina |
|---|---|---|
| Ready-mix concrete | About $160–$195+ per yd³ national guide | Replace with the delivered quote from your local ready-mix producer. |
| Installed basic concrete | About $6.50–$10.50 per ft² national guide | Use only as a broad comparison; finish, thickness and site conditions matter. |
| North Carolina sales/use tax | 6.75%–8.25% total general rate, depending on county as of July 1, 2026 | Use the rate for the project location and confirm how tax applies to your purchase or real-property contract. |
| Labor | Editable | Enter the contractor's labor/placement rate per square foot. |
| Stone base / grading | Editable | Enter a local site-prep allowance, especially where excavation or drainage work is needed. |
| Reinforcement | Editable | Use your wire-mesh, fiber, rebar or engineered reinforcement allowance. |
| Delivery / short load | Supplier-specific | Ask about minimum-load, fuel, waiting-time and distance charges. |
| Pumping | Project-specific | Add when truck access is limited or the placement plan requires a pump. |
For a slab or driveway, the calculator first converts the dimensions into cubic yards. In U.S. construction estimating, a convenient formula is length in feet × width in feet × thickness in inches ÷ 12 ÷ 27. Dividing by 12 converts inches of thickness to feet, and dividing by 27 converts cubic feet into cubic yards.
Next, the calculator adds the selected waste allowance to the geometric volume. Waste is not a universal fixed percentage. It can cover variations in excavation depth, form movement, spillage and irregular subgrade. A neat formed slab on a controlled base may need a different allowance than a complex placement or irregular excavation.
The ready-mix subtotal is the adjusted cubic-yard quantity multiplied by the price you enter. The estimator then adds a material tax amount, labor, base preparation, reinforcement and flat delivery fees. Optional driveway costs such as demolition and finish premiums are calculated separately so you can see which items are driving the budget.
Consider a 20-foot by 20-foot slab that is 4 inches thick. The area is 400 square feet. The geometric volume is about 4.94 cubic yards. With a 10% waste allowance, the order quantity rises to roughly 5.43 cubic yards.
If you use an illustrative ready-mix input of $175 per cubic yard, the adjusted concrete material subtotal is about $950 before tax and delivery. Using a 7.00% sample material-tax input adds roughly $67. Replace that percentage with the applicable rate for the project location and transaction. If you also enter $3.00 per square foot for labor, $1.25 per square foot for base preparation, $1.00 per square foot for reinforcement and a $150 delivery/flat fee, the planning budget becomes several thousand dollars. The exact result is less important than the method: every line can be replaced with a real local quote.
That same 20 × 20 slab may cost differently in Charlotte, Raleigh, Wilmington or a rural county because ready-mix travel distance, crew availability, grading conditions and minimum-load policies are not uniform statewide. The calculator is designed to make those local differences visible instead of hiding them inside one average.
Concrete cost starts with physical volume, but the final installed price also depends on site preparation, labor, reinforcement, delivery and finishing.
Delivery distance is one of the most important local variables. Ready-mix concrete is time-sensitive, heavy and expensive to haul. A project near a producer in a major metro area may have different transportation economics than a rural placement far from the batch plant. Ask whether the quoted price includes normal delivery, mileage surcharges, fuel adjustments and waiting time.
Order size also matters. Small pours can trigger short-load or minimum-purchase fees because the truck and delivery effort are similar even when you are not ordering a full load. For a tiny pad or repair, bagged concrete may sometimes be more practical; for a multi-yard slab, ready-mix is usually easier to place consistently.
Site access changes labor and equipment. A truck that can discharge close to the forms is different from a backyard pour that requires wheelbarrows, buggies or a pump. Steep grades, narrow streets, overhead lines, soft ground and long hose runs can all affect cost.
Finish and design can move the price considerably. A basic broom finish is not priced like stamped concrete, exposed aggregate, integral color, complex borders or polished work. If you are comparing decorative options, use our Decorative Concrete Calculator or Exposed Aggregate Concrete Calculator to separate volume from finish-related budgeting.
Concrete pricing is local enough that one statewide average can hide meaningful differences. Instead of inventing city-specific prices, this page uses a quote-driven method: ask a nearby ready-mix producer for the delivered price for the specified strength, mix, quantity and address, then enter that number into the calculator.
Large metro demand, traffic, access and scheduling can influence delivery. Mecklenburg's total general sales and use tax rate increased to 8.25% on July 1, 2026; verify transaction-specific treatment.
Compare supplier coverage across the Triangle, truck access, pump requirements and delivery windows. Wake County's listed total general rate is 7.25%.
Urban infill and tight sites can increase placement complexity. Durham is among counties with a 7.50% total general rate.
Use local ready-mix and contractor quotes rather than a Charlotte or Triangle benchmark; haul distance and job size can change effective cost per yard.
Western North Carolina terrain, access and grading can add site-preparation or pumping costs. Buncombe is listed among counties with a 7.00% total general rate.
Coastal projects may involve different site, drainage and exposure considerations. New Hanover is listed among counties with a 7.00% total general rate.
Homeowners often see a concrete price per cubic yard and assume that multiplying that figure by the required yardage gives the whole project cost. It does not. That calculation estimates only the ready-mix material line unless the supplier quote explicitly includes other services.
An installed project can require excavation, stone, compaction, forms, vapor barrier, reinforcement, joints, curing, finishing and cleanup. Driveways may also need demolition and disposal of an old surface. Foundations can require deeper footings, inspection and engineered reinforcement. Decorative patios add finish labor and specialty materials.
When comparing bids, ask each contractor to clarify what is included. A lower per-square-foot number that excludes excavation or reinforcement may not be cheaper than a higher all-inclusive quote. The calculator above is intentionally itemized so you can compare bids on the same basis.
North Carolina does not use one statewide all-in sales-tax percentage for general taxable purchases. NCDOR lists a 4.75% state rate plus applicable local and transit rates. As of July 1, 2026, total general rates shown by NCDOR range from 6.75% in many counties to 8.25% in Mecklenburg County, with 7.00%, 7.25% and 7.50% rates applying in other counties.
Concrete and construction transactions also require attention to who is making the taxable purchase. NCDOR explains that a real-property contractor is generally the consumer of items purchased, installed or applied to fulfill a real-property contract. Because contract structure and sourcing matter, this calculator treats the tax percentage as an editable planning input and applies it only to the ready-mix material subtotal. It is not intended to reproduce a contractor's tax accounting.
If your supplier quote already includes tax, set the tax field to 0 to avoid double counting. For current county rates and real-property-contract guidance, use the NCDOR current sales and use tax rates and NCDOR real property contracts pages.
Concrete cost is not only a dollars-per-yard question. North Carolina stretches from mountain climates to the Piedmont and coast, so drainage, soil, exposure, site access and code requirements can vary meaningfully by project location. A structural footing, retaining element or foundation should not be priced as though it were a simple four-inch patio slab.
Exterior concrete benefits from appropriate subgrade preparation, jointing, curing and mix selection. Coastal exposure, heavy rainfall, mountain freeze-thaw cycles and steep sites can create different design or placement needs. The construction documents and local code official should control structural thickness, strength and reinforcement for regulated work.
If you are calculating slab volume first, use our Concrete Calculator. For equal-sided pads, the Square Concrete Calculator is quicker. After you have yardage, return here to add North Carolina-specific supplier, labor and delivery inputs.

Concrete slabs: garage floors, shed pads, workshop floors and equipment pads are usually easy to model from length, width and thickness. Remember to include thickened edges separately if the design has them.
Patios: a basic patio may be straightforward, but decorative finishing, steps, curves, borders and difficult backyard access can raise labor and material handling. The geometric yardage may be only part of the final price.
Driveways: driveway pricing is sensitive to thickness, subbase, reinforcement, width, demolition and approach geometry. Use the driveway tab to separate these line items.
Footings and walls: calculate each continuous footing, pier or wall segment separately and then combine the cubic yards. Structural dimensions should come from approved plans or professional guidance.
Bagged-concrete jobs: small posts, repairs and tiny pads may be easier to handle with dry mix. Use our Concrete Bags to Cubic Yards converter to compare bag quantities with ready-mix volume.
The safest way to reduce cost is to improve planning, not to arbitrarily remove concrete or reinforcement. Measure carefully so the order is realistic. Coordinate excavation, forms, reinforcement and the pour schedule so the crew is ready when the truck arrives. Delays can create waiting-time charges and placement problems.
Get multiple local quotes using the same project description. Specify the estimated cubic yards, required compressive strength, delivery address, expected pour date, discharge method and whether you need a pump. Ask about short-load fees, Saturday charges, minimum order, environmental or fuel fees and waiting time.
For installed work, compare scopes rather than headline prices. One contractor may include stone base, compacting, mesh and saw-cut joints while another lists them as extras. A detailed written scope makes cost comparisons more meaningful and reduces surprises.
This tool is an estimator, not a contractor bid. It does not inspect soil, determine structural thickness, design reinforcement, verify drainage, calculate permit fees, account for every truck surcharge or predict contractor availability. It also cannot know whether your project requires excavation equipment, pumping, special admixtures, heated or chilled concrete, accelerated schedule work, curb forming or decorative finishing.
Use the result to prepare a budget and to ask better questions. Then obtain local supplier and contractor quotes before ordering or signing a contract. For large, structural or code-sensitive work, use plans prepared or reviewed by appropriately qualified professionals.

Quick answers about concrete prices per yard, slab budgets, North Carolina tax, delivery and local cost differences.
There is no single statewide posted price. National 2026 planning guides place ready-mix broadly in the mid-$100s per cubic yard. Use a current quote from a North Carolina ready-mix producer for the strength, quantity and delivery address you need.
Concrete Network gives a national planning guide of about $6.50 to $10.50 per square foot for materials and labor. North Carolina projects can fall outside that range depending on thickness, access, prep, reinforcement and finish.
North Carolina has a 4.75% state sales and use tax rate plus applicable local and transit rates. Total general rates vary by county; as of July 1, 2026 Mecklenburg is 8.25%. Confirm the project location and transaction before applying a rate.
A 20 ft × 20 ft slab at 4 inches thick is about 4.94 cubic yards before waste. With a 10% allowance, the quantity is about 5.43 cubic yards.
Small orders may trigger short-load or minimum-purchase fees because dispatching and delivering the truck still carries significant fixed cost. Ask the supplier about minimum yardage and short-load charges.
The correct allowance depends on form accuracy, subgrade variation and job conditions. This calculator defaults to 10% as an editable planning input, not a universal requirement.
Yes. The slab and driveway estimators include editable labor-per-square-foot fields along with base preparation, reinforcement and delivery fees.
No. Supplier locations, delivery distance, local demand, contractor schedules, access and tax rates can differ. Use quotes tied to the actual project address.
Only when the placement plan or site access requires one. The ready-mix order tab includes a separate pump/placement fee so you can add an actual quote when needed.
Yes for budgeting uniform concrete volumes. Structural dimensions, reinforcement and frost-protection requirements should come from the applicable plans, code and qualified professionals.
