Rebar, forms, pump, base, removal, permits, etc.
Plan for Kansas City, St. Louis, Springfield, Columbia and surrounding Missouri markets.
Use your actual local ready-mix quote rather than relying on a fixed statewide average.
Model small-order surcharges separately from the base concrete rate.
Add placement, finish, reinforcement, pumping and other job-specific costs.
For early planning, current 2026 references for concrete cost in Missouri place ready-mix material in the Kansas City and St. Louis markets around $130 to $200 per cubic yard. That is a useful budgeting band, but it is not a supplier quote. Actual prices can move below or above the range based on the batch plant, haul distance, PSI, admixtures, order size, seasonal demand and fees.

Missouri also has local supplier and small-batch options. For example, Kansas City-area U-cart pricing can be much higher on a per-yard basis because it is sold in small quantities, while normal full-truck ready-mix pricing uses a different delivery model. Compare like with like when evaluating quotes.
For a material-only estimate, calculate the cubic yards, add a waste allowance and multiply by your supplier's per-yard rate. Then add any known fixed delivery or project charges.
Use the first calculator above for this calculation.
For a rectangular slab:
Add 5–10% waste or the allowance appropriate to your project.
The table below uses a $165/yd³ planning rate and 10% waste to show how the math works. Replace that rate with your Missouri supplier quote for a useful estimate.
| Slab Size | Thickness | Base Yards | With 10% Waste | Material @ $165/yd³ |
|---|---|---|---|---|
| 10 × 10 ft | 4 in | 1.23 yd³ | 1.36 yd³ | $224 |
| 12 × 12 ft | 4 in | 1.78 yd³ | 1.96 yd³ | $323 |
| 12 × 20 ft | 4 in | 2.96 yd³ | 3.26 yd³ | $538 |
| 20 × 20 ft | 4 in | 4.94 yd³ | 5.43 yd³ | $896 |
| 20 × 24 ft | 4 in | 5.93 yd³ | 6.52 yd³ | $1,076 |
| 24 × 24 ft | 4 in | 7.11 yd³ | 7.82 yd³ | $1,291 |
Ready-mix is time-sensitive and expensive to haul. A job near a plant may have a different delivered cost from a rural location or an address reached through congested metro traffic. The exact plant-to-site distance can matter more than a statewide average.
Higher PSI, air entrainment, fibers, accelerators, retarders, pump mixes and specialty specifications can change the price. Missouri's freeze-thaw exposure also means exterior concrete often requires attention to durability and air entrainment where specified by the project or applicable standards.
Small orders may carry short-load or minimum-load charges. National 2026 guides commonly show small-order premiums around $40–$60 per cubic yard, while individual suppliers may charge a flat minimum instead. Enter the supplier's actual policy in the calculator.
If a truck cannot reach the placement area, you may need a line pump, boom pump, buggy or additional labor. Pump mobilization can be a major cost on small pours.
Excavation, granular base, compaction, vapor barrier, reinforcing steel, welded wire, thickened edges and drainage are outside the basic ready-mix price. Installed contractor bids often include some or all of these items.
Broom finish, smooth trowel, exposed aggregate, colored concrete, stamped patterns and polishing require different labor, materials and timing. Decorative concrete can substantially increase installed cost even if the cubic-yard material rate stays the same.
A small patio, footing, pad or repair may need only a few yards. The base concrete price alone can make a small job look cheap, but truck utilization and dispatch costs often create a surcharge.
At the calculator's $165/yd³ placeholder, a 4-yard order costs $660 in base material. If you model a $50/yd³ short-load surcharge, that adds $200 and produces an estimated $860 before other fees. The effective rate becomes $215 per cubic yard.
Usually priced by cubic yard, with delivery conditions defined by the supplier. This does not automatically include site preparation, forms, reinforcement, pumping, placement or finishing.
Use calculator tabs 1–3 for material and small-order planning.
Installed pricing can include grading, forms, stone base, reinforcement, labor, finishing, cleanup, equipment, overhead and profit. Kansas City and St. Louis cost guides show that labor and site work can be a large share of the total.
Use tab 4 with a local contractor's square-foot rate.
A current 2026 Kansas City foundation-cost guide places ready-mix at roughly $130–$200 per cubic yard and reports forming/pouring/finishing labor around $6.66–$11.55 per square foot for the modeled foundation work. Those figures are planning estimates rather than live supplier quotes, but they show why an installed project cannot be estimated from material price alone.
The Kansas City metro has multiple ready-mix plants on both the Missouri and Kansas sides. Delivery location, bridge/traffic routing, project access and batch-plant availability can all affect the final quote.
A current 2026 St. Louis driveway-cost guide also places ready-mix at about $130–$200 per cubic yard, with labor for forming, pouring and finishing around $5.16–$8.39 per square foot in that model. Another St. Louis patio guide shows installed project totals several times higher than raw ready-mix material because labor and site preparation are included.
St. Louis-area suppliers commonly provide quote forms rather than static public pricing, which is another reason to treat online ranges as planning guidance and request current job-specific numbers.

Driveway cost depends on thickness, reinforcement, subgrade, drainage, demolition, access and finish. Four inches may be common for light residential flatwork, but vehicle loads, weak soils, municipal requirements or design details may call for more. Use the slab calculator for material volume, then obtain an installed quote that clearly states excavation, base, reinforcement, joints and finishing.
Patios and sidewalks often use less concrete than driveways but can have a higher installed cost per square foot because of forming, curves, access and finish complexity. Stamped patterns, integral color, exposed aggregate and decorative borders add labor and materials. If the truck cannot reach the placement area, pumping or wheelbarrow/buggy labor can also increase cost.
Missouri experiences freezing winters and hot summers. Exterior slabs therefore need attention to drainage, base preparation, joints, curing and mix durability. Air-entrained concrete is commonly specified for freeze-thaw exposure, but the correct mix should come from the project specifications, supplier, contractor or engineer.
Do not substitute an online cost assumption for structural or durability requirements. A cheaper mix that does not meet the project specification can be more expensive if the work fails prematurely.
Measure accurately and include an appropriate waste allowance.
Have PSI, slump, air and admixture requirements ready.
Delivery distance and plant location affect the quote.
Short-load, waiting, fuel and after-hours fees matter.
Make sure competing suppliers quote the same mix and service.
This page uses current 2026 local planning ranges but keeps every cost input editable because concrete is quoted locally and changes with mix design, delivery and order size.
