Estimate Ready-Mix, Delivery & Installed Project Cost
Use this Concrete Cost in California calculator to estimate cubic yards, ready-mix material cost, delivery and project extras for slabs, patios, driveways, walkways and other concrete work. Enter your own current California supplier or contractor rates for a location-specific budget.
Estimate a slab from dimensions, price a known cubic-yard order, build an installed square-foot budget, or combine multiple concrete sections.
Calculate cubic yards from dimensions, then apply your current ready-mix rate, delivery and project-specific fees.
Example planning value only—replace with a current local quote.
Use this panel when you already know how many cubic yards you plan to order.
Build an installed budget using your own per-square-foot rates for site preparation, concrete placement, reinforcement and finish.
Combine several square-foot sections that use a common thickness, waste factor and ready-mix rate.
The cost of concrete in California depends on more than a single price per cubic yard. A ready-mix quote typically reflects the concrete mix itself, the distance from the batch plant, how many cubic yards are ordered, truck scheduling, and any service charges that apply to the delivery. The installed project price can then add excavation, grading, compacted base, forms, reinforcement, pumping, placing, finishing, curing, demolition and contractor labor.
For a current public reference, a Vacaville-area supplier price list dated April 2026 shows several standard mixes from about $162 to $199 per cubic yard, depending on sack content and strength, before job-specific fees. A broader national concrete pricing guide reports ready-mix commonly around $160 to $195 or more per cubic yard and cites a 2025 national average of $179.95. California jobs can land below, within or above those examples depending on local market and project conditions, so this page intentionally keeps the calculator rate editable.
For rectangular slabs, begin with surface area and thickness. Convert thickness from inches to feet, multiply area by depth to get cubic feet, divide by 27 to get cubic yards, and then apply the waste allowance. The final material estimate is the order quantity multiplied by your local price per cubic yard.
Example: 20 ft × 15 ft × (4 in ÷ 12) ÷ 27 = about 3.704 yd³ before waste.
Add delivery, short-load, pumping and other quoted charges after calculating the material subtotal.
If you add 10% overage to 3.704 yd³, the planning order becomes approximately 4.074 yd³. At an example rate of $180 per cubic yard, the ready-mix subtotal is about $733 before delivery and other charges. This is only an arithmetic example; use the rate and waste allowance appropriate to your actual job.
These figures are useful for understanding the structure of a concrete budget, but they should not be treated as a California price guarantee. Public supplier lists can change, specialty mixes can cost more, and a small order may incur service charges that materially change the effective cost per yard. For this reason, the calculator separates the base ready-mix rate from delivery and other fees.
The table below shows concrete quantity for common slab sizes at 4 inches thick with 10% overage. The cost column uses an illustrative $180 per cubic yard material rate only, before delivery, pumping, labor, reinforcement or other charges. Replace that example rate with your local quote for budgeting.
| Slab Size | Area | Raw yd³ | With 10% Overage | Material @ $180/yd³ |
|---|---|---|---|---|
| 10 × 10 ft | 100 ft² | 1.235 yd³ | 1.358 yd³ | $244.44 |
| 12 × 12 ft | 144 ft² | 1.778 yd³ | 1.956 yd³ | $352.00 |
| 12 × 20 ft | 240 ft² | 2.963 yd³ | 3.259 yd³ | $586.67 |
| 15 × 20 ft | 300 ft² | 3.704 yd³ | 4.074 yd³ | $733.33 |
| 20 × 20 ft | 400 ft² | 4.938 yd³ | 5.432 yd³ | $977.78 |
| 20 × 30 ft | 600 ft² | 7.407 yd³ | 8.148 yd³ | $1,466.67 |
| 24 × 30 ft | 720 ft² | 8.889 yd³ | 9.778 yd³ | $1,760.00 |
| 30 × 30 ft | 900 ft² | 11.111 yd³ | 12.222 yd³ | $2,200.00 |
Plant availability, traffic and local demand can affect delivered pricing.
Small loads may face minimum-order or short-load charges.
Strength, aggregate, admixtures, fibers and specialty performance affect the quote.
Pump service, long hose runs or limited truck access can add cost.
Broom, smooth, exposed aggregate, color or decorative work changes installed labor.
California is a large state with many distinct concrete markets. A project in Los Angeles does not necessarily carry the same delivered rate as one in Sacramento, Fresno, San Diego, the Bay Area or a rural county. CalPortland lists ready-mix plants across California, while CEMEX operates ready-mix service in Northern California and other markets. Proximity to a plant can matter because concrete is time-sensitive and transport is a real part of the delivered cost.
It is tempting to publish one dollar figure for each California city, but that can become inaccurate quickly. Supplier rates change, project access differs, and the mix ordered for a driveway may not be the same as the mix specified for structural work. A better way to use location information is to understand which cost factors are more likely to matter in each market.
The ready-mix price per cubic yard is only one layer of the budget. A homeowner may see a supplier rate and assume that multiplying it by the number of yards gives the complete project price. That calculation covers only the concrete material subtotal if the quote excludes delivery and service fees. Installed concrete can involve demolition of existing pavement, excavation, grading, crushed-rock base, compaction, forms, reinforcement, joints, concrete placement, finishing, curing, cleanup and contractor overhead.
This distinction is why the third calculator panel is based on square-foot line items. Surface-area pricing is often easier for comparing installed proposals, while cubic-yard pricing is better for understanding the ready-mix material component. When reviewing bids, ask whether the quoted number includes base preparation, rebar or mesh, pump service, finish type, sealing, demolition, disposal and permits.
Small concrete projects can have a high effective cost per cubic yard because the truck and dispatch effort does not shrink in proportion to the order. A supplier may apply a short-load or minimum-load charge when an order is below a preferred quantity. Delivery pricing can also vary with distance, zones, fuel, waiting time, Saturday service or other policies. If the truck cannot discharge directly where the concrete is needed, a concrete pump may be required and is commonly priced separately.
Do not guess these charges when a real budget matters. Ask the supplier to identify the base price per cubic yard, delivery charge, minimum-order or short-load policy, environmental or fuel charges, waiting-time terms, and any cancellation rules. If a pump is required, request a separate pump quote and enter it in the calculator's extra-fee field.
Ordering exactly the geometric volume leaves no allowance for variations in excavation depth, uneven subgrade, form movement, spillage or measurement uncertainty. CEMEX's ready-mix calculator guidance recommends adding an additional margin of roughly 10% to 15% as a general rule. That is useful planning guidance, not a mandatory percentage for every job.
Simple, accurately formed slabs on controlled subgrades may need a different allowance than irregular footings, thickened edges or rough excavations. The calculator lets you enter your own percentage so the volume calculation remains transparent. If a structural plan or supplier gives a specific order quantity, use that project-specific requirement.
The California Contractors State License Board identifies a C-8 Concrete Contractor classification for contractors who form, pour, place, finish and install specified concrete work. For hired work, verify the contractor's license status and scope through CSLB. Permit requirements are separate and are administered by the local authority having jurisdiction, so a patio, driveway approach, structural foundation or retaining element may have different requirements depending on the city or county and the exact work involved.
For work submitted in 2026, some local jurisdictions note the transition to the 2025 California Building Standards Code for applications filed on or after January 1, 2026. Always check the current building department rules for the project address rather than assuming a generic online guide covers the permit, structural or inspection requirements.
For quantity planning before pricing, use the Concrete Calculator or Square Concrete Calculator. If you are comparing bagged concrete with ready-mix, see the Cubic Yard to Bag Equivalent guide. Decorative projects can use the Stamped Concrete Calculator and Decorative Concrete Calculator. For a state-to-state comparison, you can also review Concrete Cost in Arizona.
