Convert known concrete volume into bag quantities, truck loads and an editable material-cost estimate.
Concrete prices, truck capacities, short-load fees and delivery charges vary. Use a current Cincinnati-area supplier quote.
Estimate concrete for driveways, patios and garage floors.
Calculate repeated foundation pads and post-support concrete.
Estimate straight concrete walls, curbs and rectangular sections.
Convert volume into bags, trucks and editable current pricing.
A Concrete Calculator in Cincinnati starts with finished concrete dimensions. Measure the actual slab, footing, wall or pad rather than the entire excavation, gravel base or work zone. Select the project type above and enter the dimensions.
The calculator converts cubic feet into cubic yards and applies an optional planning allowance. Small projects can be translated into bag quantities, while larger pours can be checked against truck capacity and current supplier pricing.
Use finished concrete dimensions.
Choose slab, footing, wall or delivery.
Get cubic feet and cubic yards.
Account for normal field variation.
Confirm supplier, permit and inspection requirements.
Rectangular slabs use length × width × thickness. If length and width are measured in feet and thickness is entered in inches, divide thickness by 12 before multiplication.
Use finished dimensions for patios, driveway sections, garage floors and other flatwork.
A 20-foot by 12-foot slab at 4 inches thick covers 240 square feet. Four inches equals approximately 0.333 foot.
The final ready-mix order may need to be rounded to the supplier's accepted increment.
Driveways and patios are often easy to estimate as rectangular sections. If a driveway widens, contains a parking pad or has changes in thickness, calculate each section separately so the total matches the actual concrete footprint.
| Project | Example Size | Thickness | Approx. Exact Volume |
|---|---|---|---|
| Small Patio | 10 × 12 ft | 4 in | 1.48 yd³ |
| Large Patio | 20 × 16 ft | 4 in | 3.95 yd³ |
| Driveway Section | 20 × 10 ft | 5 in | 3.09 yd³ |
| Garage Floor | 20 × 20 ft | 4 in | 4.94 yd³ |
Use the Concrete Slab Calculator for slab-specific estimating and the Rectangular Concrete Calculator for several straight-sided sections.
The Footing & Pad panel estimates square or rectangular footings under posts, columns and other supports. Enter the dimensions of one footing, then multiply by the number of identical footings.
Convert inch-based depth to feet before calculating cubic feet.
Use the Concrete Footing Calculator for dedicated footing geometry. Final footing dimensions and reinforcement should come from the project design.
Straight walls and curbs with constant cross-section can be estimated as rectangular prisms. Multiply total length by height and thickness. Where the dimensions change, calculate each portion separately.
Divide thickness in inches by 12 before multiplying.
Use the Concrete Wall Calculator for wall-specific volume planning.
Small repair areas and isolated pads may be manageable with bagged concrete. Multi-yard slabs can require many bags and mixer cycles, so ready-mix may be more practical for continuous placements.
| Bag Size | Approx. Yield Used | Bags per yd³ |
|---|---|---|
| 40 lb | 0.30 ft³ | About 90 |
| 60 lb | 0.45 ft³ | About 60 |
| 80 lb | 0.60 ft³ | About 45 |
Verify the actual bag yield on the selected product before purchasing.
Mixer-truck capacity varies by producer, vehicle and route. Enter the supplier's usable capacity rather than assuming every truck carries the same volume.
The last load may be partial and may have different pricing or minimum-load charges.
For short-load fees and truck spacing, use the Concrete Delivery Calculator.
Ready-mix concrete cost can change with mix, order size, delivery distance, fuel, minimum-load rules and supplier policies. The calculator therefore leaves the local price field editable rather than hard-coding a Cincinnati price.
Add per-truck delivery fees when applicable. Pumping, labor, reinforcement, finishing and permits are separate.
Concrete work connected to a new building, addition, foundation, structural wall or other regulated construction may require permits and inspections through the City of Cincinnati Department of Buildings & Inspections. The department coordinates permitting operations, plan examination and construction inspections for development in the city.
Cincinnati's Relevant Codes page notes that new versions of the Ohio Building Code, Ohio Mechanical Code, Ohio Plumbing Code and Ohio Electrical Code were adopted and enacted on March 1, 2024. The City's inspection guidance states that each phase of construction must be inspected for conformity with the code, building permit and approved plans.
City guidance says each phase of permitted construction must be inspected to confirm compliance with the code, permit and approved plans. Building Construction Inspections handles field inspections for residential and commercial projects, including soil, framing, plumbing, electrical, HVAC and final stages.
The exact inspection sequence depends on the approved project. Coordinate with the inspector listed on the permit and do not assume that a concrete quantity estimate determines inspection timing. Use the Concrete Pouring Checklist for material and crew preparation, but follow the permit documents for required inspections.
Cincinnati concrete projects can experience freezing winter temperatures, summer heat, storms and repeated freeze-thaw cycles. These conditions do not change the geometric volume calculation, but they can change the placement plan, curing method, protection needs and mix-selection requirements.
For winter work, use the Concrete Cold Weather Calculator. For warm-weather placement, use the Concrete Hot Weather Calculator where applicable. Always follow project specifications and qualified concrete guidance for curing and weather protection.
Foundation work may contain strip footings, isolated pads, foundation walls, piers and slabs. Estimate each geometry separately instead of applying one average thickness to the entire foundation.
Related tools include the Concrete Foundation Calculator, Concrete Pier Calculator, Concrete Rebar Weight Calculator and Concrete Control Joint Calculator.
Cincinnati projects can involve sloped lots, narrow urban streets, tight driveways, retaining-wall locations and restricted truck staging. Before ordering, confirm where the mixer can safely park, whether a pump or conveyor is needed and how quickly the crew can discharge each load.
For larger pours, coordinate delivery spacing so trucks do not arrive faster than the crew can place and finish the concrete. Use the Concrete Delivery Calculator for load planning and the Concrete Mixer Capacity Calculator when working with site-mixed batches.
For concrete design, construction and ready-mix information, consult the American Concrete Institute (ACI) and National Ready Mixed Concrete Association (NRMCA). Final dimensions, thickness, concrete strength, reinforcement and structural details should follow approved project requirements.
Measure the project, calculate cubic yards, add a planning allowance and verify supplier and City requirements.
