Work out the cubic yards, truckloads and concrete cost for a slab, footing or wall. The numbers update as you type.
For odd shapes. Replaces length times width.
5 to 10% covers an uneven base and what stays in the chute.
A full mixer carries up to about 10 yards.
Default: the 2025 US average, $179.95 (Concrete Network). Type in your plant’s price.

Worked examples: exact cubic yards, then the yards to order with 5 percent extra, and the number of 10-yard trucks.
| Pour | Size | Yards | Order | Trucks |
|---|---|---|---|---|
| Equipment pad | 10 x 10 ft, 4 in | 1.23 | 1.5 | 1 |
| Shop floor | 30 x 40 ft, 4 in | 14.81 | 16 | 2 |
| Small warehouse | 40 x 60 ft, 6 in | 44.44 | 47 | 5 |
| Warehouse slab | 20,000 sq ft, 6 in | 370.37 | 389 | 39 |
| Continuous footing | 200 ft run, 24 x 12 in | 14.81 | 16 | 2 |
| Foundation wall | 100 ft x 8 ft high, 8 in | 19.75 | 21 | 3 |
The engineer or the project specification sets the thickness. These are the ranges we see most often, and they match our guides to parking lot thickness and warehouse slab thickness, PSI and joints.
| Use | Typical thickness |
|---|---|
| Car parking stalls | 4 to 5 inches |
| Drive lanes with occasional trucks | 5 to 6 inches |
| Truck lanes and loading areas | 6 to 7 inches |
| Truck courts, dock aprons, dumpster pads | 7 to 8 inches or more |
| Warehouse floors | 6 to 8 inches |
The calculator multiplies the yards you order by the price per yard. The default of $180 is close to the 2025 US average of $179.95 a yard reported by Concrete Network. Your plant’s price will differ, so type it in.
The figure leaves out delivery fees, short-load and winter charges, the stone base, reinforcement, forms and labor. Our guide to what a yard of concrete costs in Ohio covers each of those.
We place warehouse floors, industrial slabs, footings, walls and parking lots across Ohio, Indiana, Michigan, West Virginia and Pennsylvania. Send the plans and an estimator replies within 24 hours.
Multiply the length by the width by the thickness, all in feet, and divide by 27. A 40 by 60 foot slab at 6 inches is 40 x 60 x 0.5 = 1,200 cubic feet, or 44.4 cubic yards. Add 5 to 10 percent and round up when you order.
A cubic yard covers 81 square feet at 4 inches thick, 65 at 5 inches, 54 at 6 inches and 40.5 at 8 inches.
Order 5 to 10 percent more than the exact volume. The extra covers a base that is not perfectly flat, forms that bow a little and the concrete left in the chute and pump. Running short in the middle of a pour costs far more than a little left over.
A full mixer truck carries up to about 10 cubic yards. Plants charge a short-load fee when an order is under their minimum, so ask before you order a small load.
No. The calculator prices the concrete only. Concrete Network puts a plain slab, materials and labor, at $6.50 to $10.50 a square foot in 2026, which covers the base, forms, reinforcement, placing and finishing.
