Free concrete cost calculator
What the pour costs, fees and all
Give it a cubic yardage and the prices you were quoted, and this costs the same pour two ways: bags at store price, and ready-mix with the charges that never appear in the price per yard — delivery, the short-load fee, a Saturday, the washout, the pump and the standby minutes past the free unloading time. It works out where the two routes cross over at your own numbers, keeps the contingency on its own line, and supplies no prices of its own.

This page starts from a volume and does no geometry of its own — bring the yardage from the concrete calculator or the slab take-off.
the load size below which plants commonly add a short-load charge: usually somewhere between 3 and 5 yards. It moves with the plant, the season and how far the truck is coming, so put your own plant’s threshold in and the fee below only counts when the load is under it.
Charges that land on the delivery
the unloading time typically allowed before standby starts, around 5 to 7 minutes a yard — so the free time here is worked out from the billed yardage, and only the minutes past it are charged. Terms vary with the supplier's own terms — some allow a flat 30 minutes instead. The pump line is the one people forget: roughly how far from the drum a standard truck chute will place concrete, before a pump or barrows are needed, and everything past that reach is either a pump or a barrow crew.
Work around the concrete
Quantities here are typed, not derived — the two calculators upstream have the perimeter and the area already worked out.

Bags or a truck, at your prices
Enter a price per bag and a price per cubic yard and this compares them properly, fees included. Both boxes are empty on purpose: a concrete price that is right in one county is wrong in the next one, and any figure we printed here would be out of date before you read it.
At 2.5 yd this load is under your 4 yd threshold, so the short-load fee is in the total above. Push the pour over that line — by adding a path, a pad or a thicker edge — and the same fee disappears.
No line has both a quantity and a rate yet, so there is nothing to add up. Fill in what your supplier quoted and the estimate builds itself a line at a time.
How to cost a concrete pour
Volume comes from elsewhere; what happens here is the money.
Bring a volume in from upstream
This page does no measuring at all: it starts from the cubic yardage the shape calculators produce, so that the same pour is not worked out twice in two places and quietly differently. Paste or retype the yardage, and add the finished square footage as well if you want the total reduced to a rate you can set against somebody else's.
Enter what you were actually quoted
Two prices drive everything: what a bag costs at the store today and what your plant charges per cubic yard. Then fill in the charges that live on the ticket rather than in the price — delivery, the short-load fee and the load size it starts under, a Saturday, a washout, a pump. Each is its own field because each is its own negotiation, and a blank field adds nothing rather than a guess.
Read the crossover, then the itemized total
The comparison box gives the cheaper of the two routes at your figures and the yardage where they swap over, which moves with the fees rather than sitting at a fixed number of yards. Underneath, the estimate builds line by line: concrete, every fee that applies, forms, finishing, and the contingency as its own row so the total can be set beside a quote without unpicking it.
Technical specifications
| Starting point | A cubic yardage you bring in — the page asks for no dimensions and derives no geometry |
|---|---|
| Ready-mix billing | Quarter-yard steps with your plant's minimum applied, and the over-billed volume shown separately |
| Delivery charges | Delivery, short-load, Saturday or after-hours, washout and pump or barrow crew, each on its own line |
| Short-load logic | Applied only when the billed load falls under the threshold you set — 4 yd³ by default |
| Standby | Free unloading at 6 minutes per billed cubic yard, then your per-minute rate on the excess |
| Crossover | Walked in quarter-yard steps at your two prices; bags versus truck, fees included |
| Contingency | Its own row at a rate you choose, 10% by default, never folded into the unit rates |
| Prices supplied by us | None — no averages, no regional table, and nothing you type is sent anywhere |
Frequently asked questions
What is a short-load fee?
A surcharge for taking a truck out with less than a full economic load in it, usually applied below somewhere between three and five cubic yards. The plant's cost is the truck and the driver, not the concrete, so a two-yard delivery costs it almost what a nine-yard one does. That is why the fee often gets bigger as the load gets smaller, and why it is worth asking what the threshold is before deciding how much to pour: adding a path or thickening an edge to cross the line can be cheaper than staying under it.
Why is my concrete bill higher than the yards times the price?
Because the price per cubic yard is the price of the material, and the ticket carries everything else. Delivery or haulage, the short-load surcharge, an after-hours or Saturday premium, an environmental or washout charge, a fuel adjustment and standby time all sit outside the rate you were quoted on the phone. On a small residential pour those additions routinely come to as much as the concrete, which is the arithmetic this page exists to make visible before the truck is booked rather than after it leaves.
What is standby time on a ready-mix delivery?
Charged waiting time, once the truck has been on site longer than the free unloading period that comes with the load. Suppliers commonly allow around five to seven minutes per cubic yard, so a three-yard load might arrive with twenty minutes of free time attached, and every minute past that is billed at a per-minute rate. It is the one charge entirely within your control: forms finished, screeds set, a barrow crew ready and a clear path for the truck turn a standby line into nothing.
Is it cheaper to buy bags or order ready-mix concrete?
It depends on the fees, not on a fixed number of yards, which is why this page walks the crossover in quarter-yard steps at your two prices. Bagged material costs several times more per cubic foot than delivered concrete, so the bag column climbs steeply while the truck column starts high and then flattens — the fixed charges are paid whether the drum is full or empty. Where the lines meet is your crossover, and a big short-load fee or a delivery charge pushes it out, sometimes to twice the volume the rule of thumb would suggest.
Does the price per yard include placing and finishing?
No. What arrives is wet concrete at the end of a chute that reaches roughly twelve to eighteen feet from the drum; everything after that is labor. Forming, screeding, floating, troweling, edging, cutting joints and curing are usually quoted per square foot by a finisher, and getting the material to where the chute will not reach is a pump or a barrow crew charged separately again. A quote for supply and a quote for a finished slab are answers to two different questions, and this page keeps them on two different lines.
How much contingency should a concrete job carry?
Ten percent as a starting point, and kept as a visible line rather than folded into the rates. Concrete has few surprises once the hole is open compared with a remodel, but the ones it does have are expensive and quick: a subgrade that turns out soft, a form that bows and takes an extra quarter yard, rain in the window between placing and finishing. A total with the allowance built silently into every rate cannot be compared with a contractor's quote, which is the whole reason for having one.
Why does this calculator not show average concrete prices?
Because a national average would be wrong in most of the country on the day it was published and out of date within a month. Concrete is one of the most local commodities there is: the price is set by how far the plant is from the aggregate, from the cement terminal and from your driveway, and it moves with fuel and with the season. Two quotes twenty miles apart differ more than most people expect, so the fields on this page start empty and stay empty until you fill them with figures somebody has actually offered you.
About what a concrete ticket really contains
The number a plant gives you on the phone is the price of the material, and on a small residential pour it is often barely half of what arrives on the invoice. The rest is the cost of sending a mixer truck to your address and keeping it there: haulage, a surcharge for taking it out part-loaded, a premium for a weekend, a charge for washing the drum out somewhere legal, and waiting time once the free unloading period runs out. None of those scale with how much concrete you buy, which has an odd consequence — the smaller the pour, the larger the share of the bill that has nothing to do with concrete. That is also why the answer to whether to bag it is arithmetic rather than folklore. To get the yardage in the first place, the concrete calculator handles the shapes and the slab calculator produces the take-off, including the form perimeter and finished area this page prices.
Two costs sit outside both columns and get left out of nearly every comparison. The first is your own time: forty bags is a day of mixing and lifting almost two tons, and while that is free in cash terms it is not free, particularly when the pour has to stay continuous to avoid a cold joint. The second is what the concrete does not include — forms and stakes, the labor to place, screed, float and trowel it, the saw cutting afterwards, and the stone base underneath. Those are quoted per linear foot and per square foot by different trades, which is why they are separate rows here rather than hidden in a rate per yard. A supply quote and a finished-slab quote look similar and are not the same product.
The last thing worth doing with a total is dividing it. Reducing every quote to a cost per square foot on the same basis — same thickness, same reinforcement, same finish — is the only way two bids become comparable, and the cost per square foot calculator exists for exactly that step. Keep the contingency visible while you do it: a padded total cannot be checked against anything. The same discipline runs through the other estimating pages here, including the bathroom remodel cost calculator, which prices a room the same way — your rates, itemized, with the allowance as a row you can argue with rather than a multiplier you cannot see.
Where the prices you were quoted stay
Every number on this page is worked out by JavaScript running in the tab you are reading it in. Nothing you type — measurements, quantities, the prices your supplier quoted you — is uploaded, logged or kept, which is also why the calculators carry on working on a site with no signal.
Quoted rates are commercially sensitive, and this page is a deliberately poor place to collect them: there is no account, no saved estimate and no way to send the numbers anywhere. Close the tab and the figures are gone, including from us.
