A concrete price calculator is different from a concrete cost calculator in one way that matters: the cost calculator multiplies yards by a price you already have, and the price calculator is for the person who does not yet have it. The price per yard a supplier quotes is built from the mix, the strength, the admixtures, the delivery distance and the load size, and the delivered price of a pour adds charges that never appear in the per-yard figure: a short-load charge under the truck's minimum, waiting time on site, a pump, a Saturday. This page sets out what the price is made of, works a 6.6 yard pour at this site's example price of $150 a yard, and says what to ask the plant. The concrete calculator on this site prices any pour from the figure you get.
What the price per yard is made of
The base price is for a standard mix at a stated strength delivered within a stated radius. Strength moves it: a higher design strength uses more cement per yard and costs more. Admixtures move it: air entrainment for freeze-thaw, a retarder for a hot day, a water reducer for a pump mix, fiber. Aggregate moves it: a small-stone mix for a thin slab or a pumped pour. Distance moves it: plants price by zone. So the first question to the plant is not what is your price but what is your price for this mix, this strength, this address, and a written quote names all four. The Census Bureau's construction spending series, linked below, is a reference for the direction of construction prices nationally, not a substitute for the plant's own quote.
The charges that sit outside the per-yard price
A truck has a minimum load, and an order under it pays a short-load charge per yard short. Waiting time is charged after a stated free period on site, so a form not ready when the truck arrives costs money by the minute. A pump is a separate hire with its own minimum. Weekend or after-hours delivery carries a surcharge. A returned load, concrete ordered and not placed, is charged and sometimes charged extra for disposal. None of these is in the $150 a yard, and a price calculator that stops at yards times price has priced the concrete and not the pour. The worked pour below adds each one where it applies.
The worked pour: 6.6 yards delivered
The pad on this site's concrete pad calculator takes 6.6 yards with waste. At the example price of $150 a yard the concrete is $990. If the plant's minimum load is larger than the order, the short-load charge applies to the yards short; if the pad is behind a house with no chute access, a pump adds its hire; if the crew is two people and the truck waits past the free period, waiting time adds per minute. A realistic delivered figure for a small pad is therefore the $990 plus one or two of those lines, and the plant's quote sheet says which. The free concrete calculator on this site takes the price per yard and the charges you enter and prints the delivered price of the pour.
What to ask, and keeping the quote against the job
Ask for the price per yard for the mix and strength the job needs, delivered to the address; the minimum load and the short-load charge; the free waiting time and the rate after it; the pump price if one is needed; the surcharges for the day and hour. Write the answers on the estimate's concrete line, because the price on the estimate is the price that has to survive to the invoice. DrawScheduleWorks Pro keeps the quoted line beside the ticket and the invoice so the difference is visible when it happens. The construction standard for concrete work, linked below, governs the placing side; the price side is the plant's sheet and the questions above.
Questions people ask about concrete price calculator
How is the price of concrete per yard set?
By the mix and strength, the admixtures, the aggregate size, and the delivery zone, quoted by the plant for a stated address. Ask for the price for this mix, this strength, this address, in writing.
What charges are added to the per-yard price?
A short-load charge under the truck's minimum, waiting time past the free period, a pump hire, weekend or after-hours surcharges, and a charge for a returned load. None of them is in the per-yard figure.
What does a 6.6 yard pour cost?
At this site's example price of $150 a yard, $990 of concrete, plus whichever charges apply to the site and the day. The concrete calculator on this site prices a pour from your own supplier's figures.
