Concrete Cost Calculator
Estimate ready-mix concrete quantity and material cost using your slab dimensions, local price per cubic yard and delivery charge.
Project and price
Estimate
This is a material-planning estimate, not a contractor quote. Taxes, pumping, reinforcement, base preparation, forms, labor and other project costs are not included unless you add them separately.
How the concrete cost estimate works
The calculator first estimates cubic yards after waste. It multiplies that quantity by the price you enter per cubic yard, then adds the delivery or short-load charge you provide.
Use a local quoted price
Concrete pricing and delivery rules vary by location, supplier, mix design and order size. Replace the default price with a current local quote before using the result for budgeting.
What is not included?
Excavation, gravel base, reinforcement, forms, finishing, pumping, permits, taxes and labor can materially change the full installed cost. This calculator focuses on ready-mix material and the delivery charge you enter.
Concrete planning guide
Concrete cost planning combines volume with local material or delivery pricing, so the result is a budget estimate rather than a contractor quote. Ready-mix rates, short-load fees, delivery distance, bag prices, taxes and site access vary by location; compare the calculated quantity with current local quotes before committing to a pour.
Turning the estimate into an order
Calculate the base requirement first, then convert it into the supplier’s orderable cubic-yard quantity. Before ordering, verify quoted price per cubic yard, short-load charges, delivery fees and the specified mix. Round only at the final purchasing step so intermediate rounding does not quietly inflate the estimate.
What changes the field quantity
Concrete invoices can include more than the base material rate. Small-load minimums, fuel or environmental fees, waiting time, additives and weekend delivery can materially change the total.
Handling a non-rectangular project
Estimate every footing, slab and thickened section separately, combine the cubic yards, then request a supplier quote using that total and the required mix specification.
Mistakes worth checking
- Treating the posted per-yard rate as the delivered total
- Ignoring short-load or minimum-load charges
- Leaving thickened edges out of slab volume
- Comparing quotes with different strength or additive requirements
Order-size and thickness decision check
Compare the calculated ready-mix volume with a practical whole-yard quote, bagged-mix yield, and a thicker slab. These are alternatives for planning, not recommendations for structural thickness.
Whole-yard ordering is an illustration only: many suppliers accept fractional-yard quantities, impose minimums, or charge short-load fees. Bag yield varies by product and conditions. Confirm required thickness and reinforcement with project documents and local rules.
Concrete cost by cubic yard: worked examples
If you are comparing a supplier quote with a project estimate, it helps to see the math at common order sizes. The examples below use an illustrative $150 per cubic yard material rate before delivery, tax, pumping, additives or short-load charges. Replace $150 with the price quoted in your area.
| Ready-mix quantity | Material at $150/yd³ | What to verify |
|---|---|---|
| 1 yd³ | $150 | Small orders may trigger minimum or short-load fees |
| 5 yd³ | $750 | Confirm delivery and mix specification |
| 10 yd³ | $1,500 | Check truck capacity and pour schedule |
| 14 yd³ | $2,100 | A project may require more than one truck |
| 20 yd³ | $3,000 | Coordinate multiple loads and placement time |
These are arithmetic examples, not market-price claims. A delivered quote can be materially different.
Example: estimating 14 cubic yards
At an entered price of $150 per cubic yard, 14 yd³ of concrete produces a $2,100 material subtotal. If your supplier quotes a $225 delivery or small-load charge, the calculator would show $2,325 before taxes and any project costs not entered. This is why two projects with the same concrete volume can have different delivered totals.
Why “price per cubic yard” is not the whole invoice
A useful quote comparison separates the base ready-mix rate from order-size minimums, delivery distance, waiting time, mix upgrades, fiber or other admixtures, pumping and taxes. Ask suppliers whether each item is included or added separately so you compare like with like.
When bags may make more sense than ready-mix
For a very small repair, bagged concrete may avoid truck minimums but requires mixing and handling. For larger pours, ready-mix can reduce mixing labor and improve placement speed. Use the quantity result first, then compare the complete delivered or bagged-material cost for your actual project.
Concrete cost FAQ
Why is there a delivery charge field?
Suppliers may apply delivery, minimum-order or short-load charges. Enter the amount from your supplier if applicable.
Does this estimate labor?
No. Labor and installation costs vary widely and are intentionally excluded.
Should I use the default $150 per cubic yard?
No. It is only an editable starting value. Use a current local supplier price for a meaningful budget estimate.
Worked project example: Concrete patio: comparing a thin slab with a thicker pour
A homeowner is planning a 12 ft × 18 ft rectangular patio. At 4 in thick, the geometric volume is 72 ft³, or about 2.67 yd³ before waste. A 10% allowance raises that to about 2.93 yd³. If the supplier sells whole cubic yards, an order of 3 yd³ is a starting point, subject to the supplier’s minimum load and site conditions.
What changes when the assumption changes?
At 5 in thick, the same footprint needs 90 ft³, or 3.33 yd³ before waste. With 10% allowance it becomes about 3.67 yd³, so whole-yard ordering may increase from 3 to 4 yd³. That one-inch design change can change the delivery tier, not just the calculated volume.
Before you purchase
Do not select slab thickness from this example alone. Soil, reinforcement, loads, frost exposure and local requirements can change the specification.
