Already know the square footage? Convert area and slab thickness into cubic yards, bag quantity and material cost.
The calculator works from geometry, so the first step is measuring the actual concrete dimensions. For a slab, patio or driveway panel, measure finished length and width and enter the planned slab thickness. For a footing, measure total continuous length and use the actual width and depth from the project design. For posts or piers, use the finished diameter and poured height/depth.
After calculating exact volume, compare it with an optional allowance. The allowance is not a mandatory Nevada percentage—it simply gives you a larger planning quantity to compare against the mathematical volume.
Use finished concrete dimensions.
Slab, footing, round post or area.
Use the project-specific concrete thickness.
Enter an Nevada-area supplier quote if desired.
Check permits, plans and field dimensions.
For most rectangular slabs, the concrete quantity formula is straightforward.
Cubic yards = cubic feet ÷ 27.
A 20 × 20 foot slab at 4 inches thick contains about 133.33 cubic feet, or approximately 4.94 cubic yards before an ordering allowance.
| Project | Example Size | Thickness | Approx. Concrete |
|---|---|---|---|
| Small Patio | 10 × 12 ft | 4 in | 1.48 yd³ |
| Patio / Slab | 12 × 20 ft | 4 in | 2.96 yd³ |
| Garage Floor | 20 × 20 ft | 4 in | 4.94 yd³ |
| Driveway Section | 20 × 30 ft | 5 in | 9.26 yd³ |
| Large Slab | 30 × 40 ft | 6 in | 22.22 yd³ |
These are geometric examples only. Actual thickness, reinforcement, base preparation and project design can differ.

Slabs are among the most common concrete projects in Central Nevada, including patios, garage floors, sheds, equipment pads and other flatwork. The slab calculator converts the surface footprint and thickness into concrete volume.
Do not use excavation depth as slab thickness. Excavation can also contain compacted base, drainage layers or other materials. Enter the actual concrete thickness shown on the project plan.
For a dedicated slab page, use the Concrete Slab Calculator. For floor-specific work, use the Concrete Floor Calculator.
For a rectangular patio, multiply length by width to get square footage, then multiply by slab thickness. Irregular patios can be divided into rectangles, circles or other simple shapes and calculated separately.
Use the Concrete Patio Calculator for circular and L-shaped patio geometry.
A driveway estimate should be based on the actual driveway footprint and the specified thickness. If different driveway sections have different thicknesses, calculate each section separately and add the cubic-yard quantities.
Permit, right-of-way and driveway-access requirements can vary by city, county and road authority. Check the local building or engineering department for the property before construction. For statewide building-code information, use the Nevada Department of Commerce Building Codes page.
Continuous strip footings and grade beams are calculated from total length × width × depth. The calculator does not size a footing structurally. Soil conditions, loads, building type and code requirements can affect foundation design, so use dimensions from approved plans or qualified design guidance.
For more detail, use the Concrete Footing Calculator or Concrete Foundation Wall Calculator.
Round concrete posts and piers use the cylinder formula π × radius² × height. If the project includes an enlarged footing at the bottom, calculate that footing separately. For larger structural columns, use the Concrete Column Calculator.
Concrete prices can change by supplier, mix specification, delivery distance, order size and additional service charges. Rather than hard-coding a citywide price, the calculator lets you enter a current local quote per cubic yard.
For sealer quantities after the project is ready for treatment, use the Concrete Sealer Coverage Calculator.
This Nevada concrete calculator can be used for quantity estimates in Las Vegas, Henderson, Reno, North Las Vegas, Sparks, Carson City, Mesquite, Elko and rural projects across the state. The volume formulas are the same everywhere: measure finished concrete geometry, convert thickness correctly and calculate cubic yards.
Local ready-mix prices, delivery zones, minimum-load fees, permits, right-of-way rules and construction practices can vary widely between southern and northern Nevada. Enter your own supplier price in the calculator instead of relying on a statewide average.
Nevada concrete projects—especially in Las Vegas, Henderson and other hot desert areas—can require careful hot-weather planning. High air temperature, low relative humidity, solar radiation and wind can increase evaporation and shorten the time available for placement and finishing. These conditions do not change the geometric cubic-yard calculation, but they can change batching, delivery, placement, finishing and curing procedures.
ACI PRC-305-20: Guide to Hot Weather Concreting discusses practices intended to minimize hot-weather problems, while NRMCA CIP 12: Hot Weather Concreting provides practical field guidance.
For curing schedule planning after placement, use the Concrete Cure Time Calculator.
Nevada exterior concrete should be planned around site drainage, subgrade preparation and the local climate. Southern Nevada can experience intense heat and rapid surface drying, while northern and higher-elevation areas can also experience freezing conditions. The calculator estimates material volume only; it does not design drainage, frost protection, air entrainment, base thickness or reinforcement.
Before ordering ready-mix, verify subgrade elevation, compacted base, forms, reinforcement and access. Uneven excavation or unexpected deeper areas can increase concrete volume even when the nominal slab dimensions have not changed.
Permit and inspection requirements vary by city, county, project type and whether work affects structures, public right-of-way or utilities. Nevada law generally requires compliance with the appropriate city or county building code for local construction, while the Nevada State Public Works Division provides permitting and code-enforcement services for State-owned land.
For private residential or commercial work, check the local building department or public works/engineering department for the project address. For State-owned projects, use the official Nevada State Public Works Division Permitting & Code Enforcement page.
Nevada construction requirements are administered through a combination of state and local jurisdictions. Nevada Revised Statutes require compliance with the appropriate city or county building code for local work, while the State Public Works Division maintains adopted codes for projects under its jurisdiction on State-owned land.
The State Public Works Division's currently posted adopted-code document states that projects submitted after June 30, 2025 must be designed under the newer adopted codes for that jurisdiction. For ordinary private work, verify the exact code edition and local amendments with the city or county that issues the permit.
This Concrete Calculator in Nevada is a material estimator only. It does not determine slab thickness, footing depth, reinforcement, structural capacity or code compliance.
Small repairs and pads may be practical with bagged concrete, while larger slabs, patios and footings can require many bags. The calculator lets you compare approximate bag quantity with ready-mix cubic yards.
Bag yields vary by manufacturer and product. Verify the package yield before purchasing. For larger pours, ready-mix can simplify batching but may include delivery minimums, short-load fees or waiting-time charges.
The exact mathematical quantity assumes uniform thickness, perfect forms and zero placement loss. Real job sites can differ because of uneven base elevations, over-excavation, form tolerance or concrete left in placement equipment.
The calculator's allowance field is optional. Choose the final order based on actual field conditions and supplier guidance.
Concrete is volume, so thickness must be included.
The calculator expects slab thickness in inches and converts it automatically.
Calculate each thickness zone separately.
Add deeper concrete geometry separately.
Enter a current supplier quote instead of relying on an old citywide average.
Check official Nevada permitting information for the exact project scope.
The calculator does not select slab thickness, footing size, reinforcement or concrete strength.
Roadway, bridge, curb, sidewalk and public-infrastructure concrete should follow the applicable agency plans and specifications rather than residential calculator assumptions. Nevada Department of Transportation design and construction resources should be used for NDOT work, together with the project contract documents.
For ordinary private projects, use this calculator for quantity planning and rely on the project designer, local building official and ready-mix supplier for technical requirements.
Concrete quantity comes from finished project dimensions. Weather affects placement and curing procedures, not the basic geometric volume.
Suppose a Nevada residential slab is 12 feet by 20 feet and 4 inches thick. The area is 240 square feet, and the thickness is one-third of a foot.
With a 10% planning allowance, the calculator shows about 3.26 cubic yards.
