What else you'll need
- Rebar or wire mesh — Reinforcement for slabs 4" and thicker
- Form lumber (2×4 or 2×6) — Perimeter boards to contain the pour
- Wood stakes and screws — Hold forms in place every 3–4 ft
- Expansion joint material — Control joints every 8–12 ft on slabs
- Vapor barrier (6 mil poly) — Under interior slabs on grade
- Concrete finishing tools — Bull float, hand float, edger, broom
- Curing compound or plastic sheeting — Keep surface moist for 7 days
Rookie mistakes
These are project-killing errors — not edge cases but patterns that show up on job sites constantly. Each one costs real money or wasted time.
The calculator gives net volume. Add 5–10% for waste before you call the plant — spillage, over-excavated edges, and uneven sub-base all eat into your order. A concrete truck won't come back for 0.3 yards. If you run short mid-pour, you finish with bags at twice the cost per yard, and the cold joint where the two loads met is visible forever.
PSI is strength. Slump is workability — how fluid the mix is when it arrives. A 4,000 PSI mix at 4-inch slump handles very differently than the same PSI at 7-inch slump. Asking the driver to add water to make it "easier to work" drops the strength by 200–500 PSI per gallon added. Tell the plant your PSI spec. Let them control the slump for your conditions.
Dry ground pulls moisture out of the mix before the cement fully hydrates, weakening the bottom inch of the slab — the inch that sits on the sub-base and takes all the load. Wet the base to damp (not standing water) the evening before the pour and again lightly if it dries out before the truck arrives. This costs nothing and prevents surface delamination.
Most ready-mix plants charge $50–$200 when your order falls below their minimum load (typically 5–7 cubic yards). The calculator gives you the material cost at full-load rates — it can't know your plant's minimum. A 2-yard pour that prices out at $280 in material can hit $420 after the short-load charge. Call the plant before you commit to a small-volume order.
Concrete reaches about 70% of its 28-day strength at day 7 and roughly 40–50% at day 1. You can walk on most residential slabs after 24–48 hours. But parking a car on it before day 7 causes surface spalling, and heavy vehicles (delivery truck, loaded trailer) need the full 28 days. If your pour-day temperature is below 50°F, those timelines stretch significantly — use the curing timeline calculator on this page.
The calculator estimates material cost only. A full project adds: form lumber and stakes ($50–$300 for a simple slab), mesh or rebar ($0.15–$0.30/sq ft), pump rental if the truck can't reach the pour location ($200–$600 mobilization plus per-yard), and permits for any structural concrete. On a contractor-poured job, material typically represents 25–40% of the total installed cost — the rest is labor, site prep, and equipment.
Standard residential driveways need at minimum 3,000 PSI; most contractors specify 3,500 PSI in freeze-thaw climates. Using 2,500 PSI saves roughly $2–$5 per yard in material but causes surface scaling and spalling within 3–7 winters in any state that uses road salt. The PSI upgrade on a 10-yard pour costs less than $50. The slab replacement costs $2,500–$6,000.
Pro tips
If you have multiple small projects (post holes + a small slab), schedule them on the same day. One truck with 3 yd³ is cheaper than two trips with 1.5 yd³ each.
Footings must extend below the frost depth per IBC 2024. In northern states, that can mean 36–48 inches deep — significantly more concrete than a standard 12-inch footing.
Concrete reaches about 70% strength at 7 days and 90%+ at 28 days. Driving on it too early causes surface cracking that costs more to repair than waiting.
Below 40°F, hydration stalls. Below 32°F, water in the mix expands as it freezes and ruptures the cement paste permanently — the slab looks fine until it crumbles. ACI 306 requires fresh concrete be kept above 50°F for at least 7 days. Cold-weather options: heat the mix water, use an accelerating admixture, or cover the pour with insulating blankets. If overnight temps will drop below 40°F within a week, postpone the pour.
Most jurisdictions require a building permit for any slab attached to a structure, all driveways, and footings over a certain size. HOA rules may additionally restrict surface materials, drainage direction, or total hardscape coverage on your lot. Applying for a permit after the pour often results in a stop-work order and required demolition. Processing takes 1–4 weeks in most municipalities — start the permit application before you call a contractor or schedule a truck.
Hidden costs beyond the concrete itself
The calculator gives you the material price — the per-yard cost of concrete. A real project adds several line items that never appear in that number.
Site preparation and demolition. The subgrade must be level, compacted, and topped with 4–6 inches of compacted gravel before concrete touches it. On sloped, overgrown, or previously paved sites, grading and demo can match or exceed the material cost. Tree root removal, old slab breakup, and haul-off are separate charges from any contractor.
Forming. Straight rectangular pours use standard 2×4 or 2×6 lumber staked every 3–4 feet — the materials checklist below covers this. Curves, steps, and multi-level slabs require bent hardboard or custom forms, adding labor hours. Most contractors bill forming as its own line item rather than rolling it into the per-yard price.
Concrete pump rental. If the truck can't back up within reach of the pour — backyards behind houses, elevated deck footings, or any pour more than about 60 feet from truck access — you need a line pump or boom pump. Pumping is typically billed as a flat mobilization fee plus a per-yard charge.
Permits and inspection. Most jurisdictions require a building permit for structural concrete: footings, retaining walls, and any slab attached to a habitable structure. Permit fees and required inspection stages vary by municipality — check your local building department before scheduling the pour.
The rule of thumb: material typically represents 25–40% of the total installed cost on a contractor-poured job. Labor, site prep, forming, and equipment make up the rest. The project examples above illustrate this split — on a 10×10 patio, material runs $250–$370 [1] while total installed cost reaches $850–$1,570+. Get at least three itemized bids so every line item is visible before you commit.
Ways to save on this project
DIY vs. hiring a concrete contractor
Material costs the same per yard whether you pour it yourself or a contractor does. The question is whether the labor savings justify the risk and physical effort.
DIY makes sense when:
- The job is under 1 cubic yard (post holes, a small equipment pad, patch repairs) and you're mixing bags by hand
- The site is flat and accessible — a truck can pour directly into forms without a pump
- The work is non-structural (shed pads, landscape edging, garden borders) where cosmetic imperfections don't compromise anything
Hire a pro when:
- The pour exceeds 2–3 yd³ — ready-mix begins to set within 60–90 minutes, and a crew of 3–4 can screed, bull-float, edge, and broom-finish a slab in that window. Working solo, you cannot.
- The concrete is structural (footings, retaining walls, anything bearing a load) — a cold joint, improper grade, or curing failure means breaking it out and re-pouring at full cost
- You want a decorative finish (stamped, exposed aggregate, colored/stained) — these techniques demand precise timing and are not learnable on the first pour
The labor math. Cement masons and concrete finishers earn a national median of $24.14/hour [2]. A typical 3-person crew finishing a residential slab works 4–8 hours, putting direct labor at roughly $290–$580 per job — but contractor pricing includes overhead, equipment, and margin, so the installed labor rate runs $6–$12 per square foot [2]. On a 120 sq ft patio, that's $720–$1,440 in labor alone, on top of $250–$370 in material [1].
The hidden cost of a failed DIY pour. Concrete does not forgive. A cold joint, wrong slope, or premature surface drying means jackhammering the slab, hauling debris to a C&D landfill, and buying the same material again. If you've never finished concrete, start with something small and non-structural — a stepping-stone path or a fence-post footing — before attempting a driveway or walkway.
Frequently Asked Questions
How much does a yard of concrete cost in 2026?
A cubic yard of standard 4,000 PSI ready-mix concrete costs $125–$185 USD [1], depending on your region and the batch plant's distance. If you order below the plant's minimum (typically 5–10 yards), expect a short-load surcharge—the fee varies by supplier, so ask your batch plant.
How many bags of concrete make a yard?
About 45 bags of 80 lb concrete (each yields 0.6 cu ft) or 60 bags of 60 lb concrete (0.45 cu ft each). One cubic yard = 27 cubic feet.
Is it cheaper to mix your own concrete or order a truck?
How much concrete do I need for a 10×10 slab?
A 10×10 ft slab at 4 in (0.33 ft) thick takes about 33 cubic feet (1.22 yd³). Order extra to account for waste and uneven subgrade.
What is a short-load fee?
A surcharge ready-mix plants add when your order falls below their minimum, typically 5–10 yd³. It covers the fixed cost of dispatching a truck for a partial load. The fee varies by supplier—ask your batch plant for their specific charge.
How we source these prices
Concrete prices on this page are derived from the BLS Producer Price Index for Ready-Mix Concrete Manufacturing (series PCU327320327320), published monthly. The current index (400.013, April 2026, base June 1981 = 100) is applied to USGS-documented 1981 base prices to produce the $/yd³ estimate. Ranges reflect regional and grade variance. We check FRED daily; when the index changes, the site rebuilds with the new number.
Three ways to buy concrete — each makes sense at a different project size. Bags let you mix small batches on-site with no minimum order. A ready-mix truck delivers wet concrete in bulk and saves 40–50% per yard on larger pours. Pick the row that matches your volume.
