Concrete Cost Estimator

How to use this calculator

1. Enter the pour, either as dimensions or as the cubic yards you were quoted. If you have a number from a supplier, use the volume field and skip the measuring.
2. Open the cost panel and edit the prices. The defaults are national averages and your local plant will not match them.
3. Tick labor only if you want it, and only if you gave dimensions. Finishing labor is priced per square foot, so a volume on its own cannot carry it.
4. Treat the total as a budget, not a quote. The next section is what the total is missing.

If you only need the volume, the yardage calculator is quicker. For a specific project, there are dedicated tools for a slab, a driveway and a pad, plus driveway resurfacing if the old one might be saveable, and a full guide to estimating concrete.

The concrete is the small part

Start here, because it reframes everything else on this page.

A cubic yard covers 324 divided by the thickness in inches in square feet: 81 square feet at 4 inches, 64.8 at 5 inches, 54 at 6 inches. So the price of the concrete per square foot is the price per yard times the thickness divided by 324. At $160 a yard, 4 inches of concrete is about $1.98 per square foot.

Now compare that to what flatwork actually costs installed. Cost aggregators put it at $6 to $12 per square foot. Real contracted prices are higher again: New Jersey DOT paid $2.78 per square foot for 4 inch sidewalk on one contract, and Montana DOT's 2025 averages put 8 inch concrete pavement at $9.80 per square foot on 77,000 square yards of it.

So the concrete itself is roughly 15 to 35 percent of the invoice. Everything else is delivery, labor, base, forms, reinforcement, finishing and disposal. Once you see that, the fees in the next section stop looking like a rip-off and start looking like line items.

What a yard of concrete actually costs

The best figure available comes from the industry's own association rather than from a cost website. NRMCA's Annual Performance Benchmarking Survey, published October 2024 on 2023 data, covers 174 producers representing about a third of all ready-mix delivered in the United States. That is a disclosed sample bigger than every cost aggregator combined.

That $11.57 of additional charges is the single most useful number on this page. It is 7 to 9 percent of a real bill, and the top quartile of producers bills $14.08. Those are the fees the next section itemizes.

For direction rather than level, the Bureau of Labor Statistics keeps a producer price index for ready-mix concrete, series PCU327320327320. It reached 402.65 in August 2026, up 2.28 percent year on year and 27.7 percent since January 2022. The shape matters: it ran hot through 2022 and 2023 (up 6.92 percent in 2023), decelerated in 2024, was essentially flat across the whole of 2025 at up 0.15 percent, and started climbing again in 2026. Anyone telling you concrete prices are still spiking is describing 2022.

What this calculator assumes, and how it compares. The defaults below come from a single pricing file so every calculator on the site agrees with itself. They are national averages reviewed as of 2025, and you should expect your plant to differ:

Our delivered default sits a little under the NRMCA average, which is the honest position for a national figure aimed at small residential pours rather than the full mix of commercial work in that survey. Edit it.

Current supplier price sheets, for comparison: a Houston supplier lists 3,000 psi at $130 to $145 by volume tier, a Los Angeles supplier lists $113.85 to $150.15, and a Northern California supplier lists $162 to $199 by sack count. More on what a yard costs and why in concrete cost per cubic yard.

The fees nobody quotes on the phone

These are not hidden charges. Suppliers publish them on their rate sheets. They just do not come up when you ask what a yard costs.

• Delivery, charged per load and not per yard. One California plant publishes $120 to $350 per load across seven distance zones; another lists $364 to $529 per trip. This is the biggest single reason two quotes differ, and it is a function of how far you are from the batch plant.
• Truck minimum and short load fee. Minimums run 3 to 6 cubic yards. Published short load fees run $50 to $175 per load. A county bid tabulation we found had three bidders quoting $120, $125 and $175 for the same thing.
• Standby or waiting time. You get a free unloading window, typically 5 minutes per cubic yard, then pay by the minute. Two suppliers in different states both publish $2.00 per minute. On a 6 yard load that is 30 free minutes, so a crew that is not ready is burning $120 an hour. A commercial buyer we looked at negotiated a full hour of unload time instead, which tells you how much this is worth.
• Weekend and after hours. One published sheet: Saturday plus $100, Sunday at double the weekday rate.
• Cold weather. Heated water runs $5 to $15 a yard; one county's winter heated load line was $15.50 to $19.00 between 15 November and 15 April.
• Environmental and washout. One supplier publishes a flat $55 per trip environmental fee. Washout charges get mentioned by suppliers but almost nobody publishes a dollar figure, and at least one pumping company advertises that it charges none.
• Late cancellation. Real, published, and priced in advance by sophisticated buyers. One supplier charges for cancellation inside 24 hours.

Short loads and delivery are covered in more detail in ready-mix delivery, and how much fits in a truck explains why the minimum exists.

Why "prices vary by region" is the wrong model

Every cost page says prices vary by region. Here is a better version of that, with a receipt.

A county public works department put ready-mix out to bid in March 2025 and published the tabulation. Same 4,000 psi mix, same month, same buyer, four quadrants of one county:

That is a 1.65 times spread inside a single county. The driver is haul distance from the nearest batch plant, not the state you live in. A state-level price map cannot represent that, and the same plant's own published delivery charge spanning $120 to $350 across seven zones is the mechanism.

So the useful question is not "what does concrete cost in my state," it is "how far am I from the nearest plant, and is there more than one within range." Two quotes is the minimum. Three is better, and the third one is often the cheap one because a different plant is closer than you thought.

There is a second effect worth knowing, and it is about quantity rather than distance. On one New Jersey DOT contract the same bidder, on the same day, was paid $2.78 per square foot for 4 inch sidewalk on 500 square yards and $20.00 per square foot for 6 inch sidewalk on 52 square yards. A 7.2 times spread, driven almost entirely by the quantity. The unit price is a function of how much you are buying, not a property of the material. That is why a small residential pour costs so much more per yard than the numbers contractors quote each other.

Labor, and why it is the part that is inflating

The Bureau of Labor Statistics tracks cement masons and concrete finishers as occupation 47-2051. The median wage is $27.41 an hour, or $57,020 a year, on 2025 data.

Two things make that number more interesting than it looks.

First, prevailing wage work is a different market. California's determination for 43 northern counties, issued August 2025, sets a cement mason at $49.00 basic plus $31.06 in fringe benefits, $80.06 an hour total, rising to $104.56 for overtime and $129.06 on Sunday. That is 2.9 times the national median. If your job is public work, or in a strong union market, the labor line on a private-work cost guide is not close.

Second, labor is outrunning material. The median for this occupation went from $23.22 an hour in 2022 to $27.41 in 2025, up 18 percent in three years, while the ready-mix producer price index rose 7.5 percent over the same period. If you are comparing a quote to a number you remember from a few years ago, the labor is where the difference is.

On what finishing actually costs per square foot, we have to be honest about a gap: no source we could find separates placement labor from finishing labor, and broom finish versus hard trowel is never itemized as two priced lines anywhere. Broom is the unstated baseline in every source. What we can say is that one aggregator puts labor alone at $8 to $18 per square foot, which exceeds another's figure for the entire installed job, and that disagreement is the finding.

When you need a pump, and what it costs

A mixer truck discharges down a chute. If the pour is not within chute reach of where the truck can park, you need a pump, and it is a real line item rather than an upsell.

• Line pump, trailer mounted, pumps at ground level: over 300 feet of horizontal reach, placing 15 to 30 cubic yards an hour. Published rates $150 to $250 an hour.
• Small boom pump, around 85 feet of vertical reach, 80 to 130 cubic yards an hour. $200 to $300 or more an hour.
• Large boom pump, 120 feet and up, over 150 feet vertical, 150 to 200 plus cubic yards an hour.

Minimums typically cover the first 2 to 4 hours. Real totals: under 20 yards runs $600 to $1,000, and a 30 to 50 yard driveway runs $800 to $1,500. One supplier publishes pumping on its own rate sheet as $300 setup plus $13 per cubic yard, which is the cleanest sourced figure we found.

The trade-off is not just convenience, it is finish quality. On a 40 yard pour a line pump is a 1.5 to 2.5 hour placement and a boom pump is about 20 minutes. Concrete does not wait for you, so placement speed decides whether the crew is finishing one slab or fighting three cold joints.

One figure to distrust: we found a "$3 to $5 per cubic yard" pumping number that is inconsistent with everything else by a factor of three to thirteen. Ignore it.

Everything else on a real invoice

Where a state DOT has actually paid for something, that is the number we use, because it is a real contracted price rather than an estimate. These are from Montana, South Dakota and New Jersey DOT unit price reports.

Read those with the quantity in mind. DOT prices benefit from enormous scale, so treat them as a floor rather than a residential price. The quantity effect is visible inside the data: Montana has line items at $1,464 per square yard on 17 square yards, which is pure mobilization cost spread over almost nothing. A price is only meaningful alongside the quantity it was bid on, which is the single most honest thing a cost page can tell you.

For the steel specifically, the rebar calculator will count and weigh it, and a dated retail price snapshot is on that page. For base gravel, the gravel calculator converts a volume into tons.

Two items we previously could not source above content-farm level now have figures, both with a disclosed basis. Vapor barrier: 10 mil meeting ASTM E1745 Class A runs $0.15 to $0.38 per square foot of material across five suppliers, 15 mil $0.22 to $0.67, and non-compliant 6 mil construction poly $0.06; installed, a contractor charges about $0.50. Welded wire mesh installed is $0.83 to $0.98 per square foot on a disclosed 534 square foot basis. Forms are still only published per square foot of contact area, at $4.45 to $5.44, so a per-linear-foot figure remains a derivation rather than data: at 4 inches that is about $1.48 to $1.81 per linear foot of edge, and we label it as ours. Concrete slab cost by size uses it to show forming cost per square foot of slab falling about fivefold from a 10 by 10 to a 40 by 60.

Why the numbers you find online disagree

We collected the headline figures from the five sites that dominate this search, so you can see the problem rather than take our word for it.

What that table shows:

• HomeGuide's ceiling of $147 sits below Thumbtack's floor of $150. Two national figures for the same commodity in the same year, and they do not overlap at all.
• Homewyse's minimum of $10.09 per square foot exceeds both HomeGuide's and Thumbtack's maximums.
• Angi's figure for labor alone exceeds HomeGuide's figure for the entire installed job.
• Thumbtack contradicts itself within a single page. HomeGuide contradicts itself across three.
• HomeGuide's whole per-yard range sits below what NRMCA says producers actually collected three years earlier.
• Only one of the five discloses a sample size. Only one discloses a method.

None of this means those sites are useless. It means a single number from any one of them is not a fact, and that the spread, $110 to $210 per yard and $5 to $18 per square foot, is the honest answer to "what does concrete cost." Our own defaults in the calculator above are national averages too, which is exactly why every one of them is editable.

Estimate, quote and what the law actually says

An estimate is a considered guess. A quote is an offer at a stated price. A bid is a quote in a competitive process. This page produces the first of those three.

Now the part that gets repeated everywhere and is not true. You will read that an estimate is binding within 10 or 15 percent. We looked for the statute and there is none. No state law we could find makes an estimate binding or caps how far a final price may exceed one. Every source for the 10 to 15 percent rule traces back to contractor software marketing, law firm blog posts or paid question-and-answer sites. Some states do regulate automotive repair estimates with a tolerance, and conflating that with construction is probably how the myth spread.

What the law does require is a written contract, and that is stricter than most people expect:

• California: a written contract for home improvement work over $500, the deposit capped at the lesser of $1,000 or 10 percent, and any change to price or scope needs a signed written change order before the work happens.
• Massachusetts: MGL chapter 142A section 2 requires that "every agreement to perform residential contracting services in an amount in excess of one thousand dollars shall be in writing."
• New York: General Business Law section 771 requires a signed writing for every home improvement contract with no dollar threshold at all, plus a payment schedule in dollars and cents and a three business day right to cancel.
• Wisconsin: a written contract whenever any money changes hands before the work is complete, again with no dollar threshold.

The practical version: the protection is not a percentage tolerance on the estimate, it is the written contract and the change order process. Get the total price in writing, get the scope in writing, and get any change in writing before it is built. A number off this page, or off any other calculator, is a sanity check on a quote rather than a substitute for one.

If you are the one writing the estimate, the estimate template covers markup against margin and what your state requires once a customer signs.

Cost by project

Prices shift with the shape of the job, the finish and how much of it there is. Each of these has its own page with figures for that project.

• Slab cost calculator, and what a slab costs at common sizes.
• Concrete driveway cost, concrete versus asphalt if the material is still open, and patio cost.
• Foundation cost, for slab against stem wall against basement, which is the biggest single concrete decision on a house.
• Stamped concrete cost, where the finish costs more than the concrete.
• Concrete floor cost and curbing cost.
• Pad cost calculator for equipment and spa pads.
• Cost per square foot if that is the unit you are working in.

And if you would rather mix it yourself than buy it delivered, the bag calculator counts bags and the mix calculator covers batching from bulk cement, which is cheaper per yard and a great deal more work.

Entry steps are their own problem, because the published cost guides each price a different thing and none of them prices the footing: what concrete steps cost sets the four national ranges against a real precast price list.
