Want the real quote, done for you?
This is a rough number. Vorkeon builds the full concrete quote from one sentence:
- Materials with waste, and crew time from your own pace
- Current prices from building-supply stores near the job
- A clean PDF with your logo that the customer signs on their phone
- Then the invoice, reminders and your crew's hours, in one app
What drives the price of a concrete job
- Thickness. Concrete is bought by volume, so a 6 inch slab uses half again as much as a 4 inch one.
- Base prep. Digging, gravel base and compaction are a big part of the job.
- Reinforcement. Rebar, wire mesh or fiber add material and labor.
- Finish. Broom finish is quick; stamped or colored concrete costs much more.
- Access. If the truck cannot reach, you need a pump or wheelbarrows.
- Short-load fees. Small pours often carry an extra charge from the ready-mix plant.
A worked example
Example only, made-up numbers, not a price guide. A 400 sq ft patio slab, 4 inches thick, is about 5 cubic yards (400 × 0.33 ft ÷ 27, plus a little extra). With material at 3.00 and labor at 4.00 per sq ft: 400 × 7.00 = 2,800. Add 400 for gravel base and 200 for a pump, for 3,400. With 20% markup the quote is 4,080 before sales tax. Concrete prices change by region and season.
What to put in your concrete quote
- Area, thickness and the volume of concrete ordered
- Excavation depth, base material and compaction
- Reinforcement type and spacing
- Finish, control joints and any sealer
- Pump or access costs, and old concrete removal
- Curing time, when the customer can walk or drive on it
Prices vary by region and change over time: use your own supplier prices and labor rates. Updated October 30, 2026.
Concrete quoting questions
How do I turn slab area into concrete volume?
Multiply the area in sq ft by the thickness in feet (4 inches is about 0.33 ft), then divide by 27 to get cubic yards. Order a little extra, often 5 to 10%, for uneven ground and spillage.
Do concrete quotes promise no cracks?
It is wise not to. Concrete can crack even when done right. Explain control joints in the quote and say which cracks are normal and which you would fix.
How do I price a concrete job?
Multiply the slab area by your material and labor cost per square foot, then add your markup to cover overhead and profit. Add tax on top when you send the quote.
What markup should I use?
Use the markup that covers your overhead (vehicle, insurance, tools, office) and leaves the profit you want. Many contractors land between 15% and 35%, but your own costs decide it.
