Estimate Ready-Mix, Delivery & Installed Project Cost
Use this Concrete Cost in Maryland calculator to estimate cubic yards, ready-mix material cost, delivery and project extras for slabs, patios, driveways, walkways and other concrete work. Enter your own current Maryland ready-mix supplier or contractor rates for a location-specific budget across Baltimore, Central Maryland, the DC suburbs, Frederick, the Eastern Shore and Western Maryland.
Estimate a slab from dimensions, price a known cubic-yard order, build an installed square-foot budget, or combine multiple concrete sections.
Calculate cubic yards from dimensions, then apply your current ready-mix rate, delivery and project-specific fees.
Example planning value only—replace with a current local quote.
Use this panel when you already know how many cubic yards you plan to order.
Build an installed budget using your own per-square-foot rates for site preparation, concrete placement, reinforcement and finish.
Combine several square-foot sections that use a common thickness, waste factor and ready-mix rate.
The cost of concrete in Maryland is not one fixed statewide number. A ready-mix quote can change with the concrete mix, PSI requirement, distance from the batch plant, total cubic yards, delivery window, truck access, short-load rules and any pump or waiting-time charges. Installed project cost can then add excavation, grading, compacted stone base, forms, reinforcement, placement, finishing, curing, demolition, disposal and contractor labor.
For 2026 planning context, national ready-mix guides place standard delivered concrete broadly around $125 to $195 per cubic yard, with many ordinary projects clustering near the middle of that range before job-specific add-ons. Maryland projects may fall below or above that benchmark depending on the supplier and job. The Maryland Ready Mix Concrete Association represents producers serving the state, but it does not establish one statewide retail price. That is why this calculator keeps the price-per-yard field editable instead of presenting a misleading Maryland average.
For rectangular slabs, begin with surface area and thickness. Convert thickness from inches to feet, multiply area by depth to get cubic feet, divide by 27 to get cubic yards, and then apply the waste allowance. The final material estimate is the order quantity multiplied by your local price per cubic yard.
Example: 20 ft × 15 ft × (4 in ÷ 12) ÷ 27 = about 3.704 yd³ before waste.
Add delivery, short-load, pumping and other quoted charges after calculating the material subtotal.
If you add 10% overage to 3.704 yd³, the planning order becomes approximately 4.074 yd³. At an illustrative rate of $170 per cubic yard, the ready-mix subtotal is about $693 before delivery and other charges. This is only an arithmetic example; use the rate and waste allowance appropriate to your actual job.
These figures help structure a budget, but they are not a Maryland price guarantee. Concrete is a local delivered product, and the effective cost per yard can change substantially when an order is small, the job is far from the plant, the site requires pumping, or the truck has limited discharge access. The calculator therefore separates base ready-mix cost from delivery and project-specific fees.
The table below shows concrete quantity for common slab sizes at 4 inches thick with 10% overage. The cost column uses an illustrative $170 per cubic yard material rate only, before delivery, pumping, labor, reinforcement or other charges. Replace that example rate with your local quote for budgeting.
| Slab Size | Area | Raw yd³ | With 10% Overage | Material @ $170/yd³ |
|---|---|---|---|---|
| 10 × 10 ft | 100 ft² | 1.235 yd³ | 1.358 yd³ | $230.77 |
| 12 × 12 ft | 144 ft² | 1.778 yd³ | 1.956 yd³ | $332.52 |
| 12 × 20 ft | 240 ft² | 2.963 yd³ | 3.259 yd³ | $554.03 |
| 15 × 20 ft | 300 ft² | 3.704 yd³ | 4.074 yd³ | $692.59 |
| 20 × 20 ft | 400 ft² | 4.938 yd³ | 5.432 yd³ | $923.44 |
| 20 × 30 ft | 600 ft² | 7.407 yd³ | 8.148 yd³ | $1,385.16 |
| 24 × 30 ft | 720 ft² | 8.889 yd³ | 9.778 yd³ | $1,662.26 |
| 30 × 30 ft | 900 ft² | 11.111 yd³ | 12.222 yd³ | $2,077.74 |
Concrete is time-sensitive, so haul distance and plant availability can affect delivered pricing.
Small loads may face minimum-order or short-load charges.
Strength, aggregate, air entrainment, fibers and admixtures can change the quote.
Pump service, restricted streets, long hose runs or limited truck access can add cost.
Broom, smooth, exposed aggregate, color or stamped work changes installed labor.
Maryland is compact compared with many states, but concrete markets still differ between the Baltimore region, the Washington suburbs, Annapolis and Anne Arundel County, Frederick, the Eastern Shore and Western Maryland. Traffic, corridor travel, plant proximity and local construction demand can all affect the delivered quote. Because ready-mix has a limited practical delivery window, a nearby plant can be as important as the nominal price per cubic yard.
One Maryland-wide dollar figure can be misleading because the delivered cost reflects local plants, traffic, access and the exact mix. Use the market notes below to identify which questions to ask when collecting quotes rather than treating them as fixed city prices.
The ready-mix price per cubic yard is only one layer of the budget. A homeowner may see a supplier rate and assume that multiplying it by the number of yards gives the complete project price. That calculation covers only the concrete material subtotal if the quote excludes delivery and service fees. Installed concrete can involve demolition of existing pavement, excavation, grading, crushed-rock base, compaction, forms, reinforcement, joints, concrete placement, finishing, curing, cleanup and contractor overhead.
This distinction is why the third calculator panel is based on square-foot line items. Surface-area pricing is often easier for comparing installed proposals, while cubic-yard pricing is better for understanding the ready-mix material component. When reviewing bids, ask whether the quoted number includes base preparation, rebar or mesh, pump service, finish type, sealing, demolition, disposal and permits.
Small concrete projects can have a high effective cost per cubic yard because the truck and dispatch effort does not shrink in proportion to the order. A supplier may apply a short-load or minimum-load charge when an order is below a preferred quantity. Delivery pricing can also vary with distance, zones, fuel, waiting time, Saturday service or other policies. If the truck cannot discharge directly where the concrete is needed, a concrete pump may be required and is commonly priced separately.
Do not guess these charges when a real budget matters. Ask the supplier to identify the base price per cubic yard, delivery charge, minimum-order or short-load policy, environmental or fuel charges, waiting-time terms, and any cancellation rules. If a pump is required, request a separate pump quote and enter it in the calculator's extra-fee field.
Ordering exactly the geometric volume leaves no allowance for variations in excavation depth, uneven subgrade, form movement, spillage or measurement uncertainty. CEMEX's ready-mix calculator guidance recommends adding an additional margin of roughly 10% to 15% as a general rule. That is useful planning guidance, not a mandatory percentage for every job.
Simple, accurately formed slabs on controlled subgrades may need a different allowance than irregular footings, thickened edges or rough excavations. The calculator lets you enter your own percentage so the volume calculation remains transparent. If a structural plan or supplier gives a specific order quantity, use that project-specific requirement.
For residential work, Maryland's Home Improvement Commission (MHIC) licenses and regulates home improvement contractors and salespersons. The state describes home improvement as alteration, remodeling, repair or replacement work on a residence, including individual condominium units. Concrete patios, walks, steps, driveways or repair work may fall within that framework depending on the scope and property type, so homeowners should verify the contractor and the applicable license before signing a contract.
Licensing and permit rules are not identical for every concrete project. New construction, commercial work, public work and specialized scopes can be governed differently, while building, zoning, right-of-way and driveway-apron permits are commonly handled by the local county or municipality. Check the authority having jurisdiction for the project address before excavation or placement rather than assuming a statewide rule covers every Maryland job.
For quantity planning before pricing, use the Concrete Calculator or Square Concrete Calculator. If you are comparing bagged concrete with ready-mix, see the Cubic Yard to Bag Equivalent guide. Decorative projects can use the Stamped Concrete Calculator and Decorative Concrete Calculator. For a state-to-state comparison, you can also review Concrete Cost in California or Concrete Cost in Arizona.
