Is My Concrete Quote Fair?

Enter the price on your quote and the slab it is for. We place it against our 2026 range for the same size, thickness, steel and finish in your state, with the extras your quote includes, and against what other readers in your state were quoted for the same kind and size of slab.

Check a concrete quote

Start with your state and the price. The slab defaults to a 20 x 20 ft, 4-inch patio with wire mesh; change it to match the quote.
Is this a quote or the final bill?

The slab on the quote

400 sq ft, 4.94 cu yd of concrete before waste

Does the price include…

Breaking out and removing an old slab?
Digging out and hauling away soil?
A concrete pump (truck cannot reach)?
A building permit?

Choose your state and enter the price to place your quote against the range below and against other readers’ quotes.

Our range for this slab: $2,180 to $8,190

  • Slab: 4 inches, 3,000 PSI, wire mesh, plain broom, on a 4-inch crushed-stone base$2,180 to $5,620
  • Break out and remove an old slab (not sure: top of the range only)+$0 to $1,220
  • Dig out and load soil for haul-off (not sure: top of the range only)+$0 to $980
  • Concrete pump (not sure: top of the range only)+$0 to $370
  • Building permit (fees are set by your city or county)not priced

Crew priced at national BLS wages until you choose a state. Concrete, stone and steel at published national prices. Removal from eight contractors’ bids to the Village of River Forest, IL (Dec 2025), which are municipal unit prices without a small-job minimum, so one homeowner job often prices above them. Pump at Supreme Concrete’s published rate (Los Angeles). Dig-out excludes landfill fees and trucking. Every source and date.

Quotes from other readers

How this works

Choose your state above to see what other readers there were quoted for a slab like yours.

Reader figures are volunteered and unverified. People who think a quote is unusual may be more likely to share it, so read them beside our range, not instead of it.

Choose your state and enter the price to add your quote for other readers.

How the quote check works: what your price is compared with, when reader quotes show, what we refuse and hold, and how this site makes money.

Extras you say are in the quote (removal, dig-out, pump) are added to the range; extras you are not sure about widen only its top. Permits are not priced. A stamped, exposed-aggregate or stained quote gets no verdict until we have a published source for the finish premium. Once 30 or more readers in your state have shared quotes for the same slab, your price is placed against the middle 80% of theirs instead. Every source, date, limit and rule: how the quote check works.

Method / How We Price

How We Price a Slab

Every installed price on this site comes from one model: published ready-mix and materials prices, plus crew hours priced at Bureau of Labor Statistics wages, plus overhead and margin. The low figure uses the lowest published input and our lowest assumption at every step; the high figure uses the highest. The crew hours, overage and margin are our own estimates, not published figures, and are listed below so you can check them against your quote. Worked example: a 20 x 20 ft (400 sq ft) slab (4-inch, 3,000 PSI, wire mesh, broom finish, 4-inch stone base).

LineLowTypicalHighBasis
Ready-mix concrete$659$754$8964.94 cu yd plus 5 to 10% overage, at published per-yard prices
Delivery and small-load charges$0$35$419Per-truck charges from the same price lists (10 yd per truck)
Crushed-stone base$261$325$4434 in compacted crusher run
Reinforcement$96$96$966x6 10-gauge mesh panels, lapped
Form lumber$30$45$61Perimeter boards, shared across reuses
Crew labour$770$1,332$2,101Crew hours x BLS wages x employer costs
Overhead and margin$363$776$1,60620% to 40% on direct cost
Installed total$2,180$3,360$5,620Rounded to the nearest $10

Not included: excavation and soil haul-off, removing an old slab, permits, pumping, decorative finishes and sealing. Totals are national; the calculators’ state option swaps in that state’s BLS wages and leaves concrete and materials at the published lists.

Published inputs (read 13 October 2026)

Our assumptions (estimates, not published figures)

  • Crew: half cement masons, half laborers.
  • Setup per job: 8 to 16 crew hours (layout, stripping, cleanup).
  • Per 100 sq ft: 4-inch 4 to 7 crew hours, 6-inch 5 to 8.5, 8-inch 6 to 10; add 0.5 to 1 for mesh or 1.5 to 2.5 for rebar.
  • Concrete overage 5% to 10%; base stone ordered at 1.2x its compacted volume; form boards charged at half to all of their price.
  • Overhead and margin 20% to 40% of direct cost.
  • 6-inch and thicker slabs use 4,000 PSI mix; thinner slabs 3,000 PSI.

Quote Check FAQ

Compare it with a range for the same slab and the same scope: the size, thickness, steel and finish, and whether the price includes removing an old slab, digging out, a pump or a permit. The check above does that against our cost model, and once readers in your state have shared quotes for the same kind and size of slab it shows those too. The strongest check is still a second written quote for the same slab with the same line items.
