Project Estimate
Target margin is the percentage of the selling price remaining after estimated job costs. It's different from markup.
Your current margin is 11%. Consider raising your price to $7,261 to reach at least 30%.

What belongs in a complete concrete project cost
The calculator above gives you a real number from your own inputs. Here's what typically drives those numbers up or down, so you know what to look for on your specific job.
Project type and use
Structural slabs, driveways, patios and sidewalks all carry different thickness and reinforcement needs, which is the main driver of concrete volume and cost.
Thickness and reinforcement
Both are set by the project's structural requirements (load, soil, code), never guessed by this tool. More of either means more material and labor cost.
Finish
A basic broom or trowel finish is the cheapest baseline. Stamped, colored, exposed-aggregate or polished finishes add material and labor.
Site access
Pours that need a pump truck, or that involve difficult access for delivery trucks, cost more than a straightforward direct-chute pour.
Regional material and labor rates
Ready-mix pricing per yard and crew labor rates vary widely by region. Always price with your own current supplier and labor numbers.
How this calculator works
- 1Area: length × width gives the footprint in square feet.
- 2Volume: area × thickness (converted to feet) gives cubic feet, divided by 27 to get cubic yards.
- 3Order quantity: your allowance percentage is added on top so you don't come up short on pour day, then rounded to whatever increment you choose.
- 4Cost and price: ready-mix, labor, forms, reinforcement and equipment costs are totaled, overhead is added for true cost, and the required price is solved for your target margin.
This calculator estimates quantities and costs from user-entered dimensions, specifications, allowances and prices. It does not provide structural design, engineering or building-code recommendations.
Choose the calculation that matches your next decision
This general calculator starts with one rectangular footprint and adds the job costs you enter. Use it when you want quantity, installation cost and optional contractor pricing in the same calculation. If the next decision is ordering material, comparing suppliers or billing completed work, the focused tools below expose the relevant details without turning every workflow into the same generic estimate.
Quantity first, then procurement
For several rectangular sections, the pour tool shows each net volume and one combined order. Use that final quantity in the ready-mix supply tool. It includes delivery, short-load fees and entered tax; those expenses should appear only once when you move into full job costing.
Supplier comparison is a different calculation
A lower quoted material rate does not necessarily produce a lower order total. Compare equivalent supplier quotes using the same quantity, specifications and delivery terms. The effective rate is total order cost divided by yards ordered, which applies only to the tested order size.
Keep internal costs and customer charges distinct
Material and crew costs are business expenses. A required selling price also accounts for overhead and your chosen margin. Put proposed customer charges in the estimate template, then use the invoice tool to record completed work, tax and received deposits. The free tools do not create an estimate archive.
Worked custom-pour quantity example
Illustrative inputs: 30 ft × 20 ft × 4 in. This sample illustrates a custom rectangular pour. Replace dimensions and every rate with the actual project scope; specialized layouts need their own specified takeoff.
- Net concrete
- 7.407 yd³
- Selected allowance
- 8%
- Order rounded upward to 0.25 yd³
- 8.00 yd³
- Material at illustrative $165/yd³
- $1,320
Material amount excludes delivery, tax, installation and contractor margin. Sample dimensions and prices are not design or local-price guidance.
Next steps for this project
Total separate rectangles before applying order allowance and rounding.
Normalize material rates and fixed fees for the same order.
Price known concrete, forms and specified reinforcement quantities.
Bill agreed customer charges and reconcile deposits and tax.

Frequently asked questions
What project types can I use this for?
Any rectangular concrete pour: slabs, driveways, patios, sidewalks, pads or custom flatwork. For multi-section quantity, use the free Concrete Pour Calculator. Concrete Cost Pro carries multiple sections through full costing and customer estimates.
How much does ready-mix concrete cost per yard?
Request a current supplier quote for your specified mix, quantity and delivery location. Enter its material price per yard here and include delivery or short-load fees once in your other costs. The sample rate is illustrative; the tool does not fetch live prices.
Is this a concrete estimate calculator, a pricing calculator, or just a quantity calculator?
All three: enter dimensions to get concrete quantity, then add your material, labor and equipment costs to turn that quantity into a full project cost estimate and, with Contractor Pricing, a target-margin selling price.
Is this the same as concrete estimating software?
This free calculator handles one-off quantity and cost math. Concrete Cost Pro (sometimes searched as concrete estimator software) adds saved rates, job costing, rate-health tracking, branded estimates and estimate-vs-actual reporting for running an ongoing concrete business.
