There is no single statewide concrete price that applies equally to Honolulu, Hilo, Kona, Kahului, Līhuʻe or smaller island communities. Concrete cost in Hawaii is shaped by island logistics, mix design, haul distance, order size, truck access, pumping requirements, labor, site preparation and the finish specified for the project. For that reason, a useful Hawaii concrete cost calculator should separate material quantity from local price inputs instead of multiplying square footage by one universal national rate.
Two public data points show why an editable calculator is more realistic. HC&D's Oʻahu ready-mix schedule effective January 1, 2025 listed normal-weight 3,000-psi concrete at $234.00 per cubic yard at the plant. The same schedule showed contractor list delivered prices of about $256.00 per cubic yard in zone 1 and $269.50 in zone 10. Later, a September 2025 Building Industry Hawaii article reported an industry estimate of approximately $350 per cubic yard for ready-mix concrete in Hawaiʻi. Those numbers are not necessarily contradictory: they can reflect different timing, suppliers, mixes, delivery conditions, quote structures and market circumstances.
The cubic-yard price is the most direct material input for ready-mix concrete. One cubic yard equals 27 cubic feet. At a 4-inch slab thickness, one cubic yard theoretically covers about 81 square feet before waste; at 5 inches it covers about 64.8 square feet; at 6 inches it covers about 54 square feet.
Then add delivery, short-load, pumping, overtime, waiting time, taxes or other quote-specific charges separately.
Using the calculator's editable $350 per cubic yard example, 3.5 cubic yards would have a base concrete value of $1,225 before delivery and placement. If the same project receives a supplier quote of $275 per cubic yard, the base material value would be $962.50. That difference is why entering the actual Hawaii quote matters more than relying on a generic national average.
| Order Size | At $275/yd³ | At $350/yd³ | At $400/yd³ | Notes |
|---|---|---|---|---|
| 1 yd³ | $275 | $350 | $400 | Small orders may trigger minimum or short-load fees. |
| 3 yd³ | $825 | $1,050 | $1,200 | Material only. |
| 5 yd³ | $1,375 | $1,750 | $2,000 | Check delivery-zone charges. |
| 10 yd³ | $2,750 | $3,500 | $4,000 | One truck capacity varies by supplier and load rules. |
| 20 yd³ | $5,500 | $7,000 | $8,000 | Large pours require scheduling and placement planning. |
Delivery charges can be a major part of concrete cost in Hawaii, especially for small projects. HC&D's January 2025 Oʻahu schedule stated a minimum delivery of 1.5 cubic yards and required orders below 6 cubic yards to use the plant price plus a minimum delivery charge for the appropriate zone. On the published schedule, those minimum delivery charges ranged from $132 in zone 1 to $213 in zone 10. The schedule also noted that retail sales add $4.00 per cubic yard to schedule delivered prices and Saturday deliveries add $2.00 per cubic yard.
The same schedule allowed unloading time of five minutes per cubic yard or 30 minutes per load, whichever is greater, with excess unloading time charged at $2.00 per minute. These supplier-specific rules show why site readiness matters. If forms are incomplete, access is blocked or the crew cannot place concrete at the truck's pace, waiting-time charges can accumulate while the concrete is already on the clock.
Homeowners often search for concrete cost per square foot in Hawaii, but square-foot pricing can mean two different things. Material-only cost per square foot comes from the cubic-yard price and slab thickness. Installed cost per square foot can also include excavation, base preparation, forms, reinforcement, labor, finishing, pumping, cleanup and contractor overhead.
At 4 inches thick, one cubic yard covers about 81 square feet. A $350/yd³ concrete price therefore represents about $4.32 per square foot of theoretical concrete material before waste and delivery. At 6 inches thick, the same cubic yard covers only 54 square feet, raising the material component to about $6.48 per square foot before waste and delivery.
| Slab Thickness | Coverage per yd³ | Material at $275/yd³ | Material at $350/yd³ | Material at $400/yd³ |
|---|---|---|---|---|
| 3 in | 108 ft² | $2.55/ft² | $3.24/ft² | $3.70/ft² |
| 4 in | 81 ft² | $3.40/ft² | $4.32/ft² | $4.94/ft² |
| 5 in | 64.8 ft² | $4.24/ft² | $5.40/ft² | $6.17/ft² |
| 6 in | 54 ft² | $5.09/ft² | $6.48/ft² | $7.41/ft² |
| 8 in | 40.5 ft² | $6.79/ft² | $8.64/ft² | $9.88/ft² |
Installed pricing is more project-specific. Instead of publishing a misleading single statewide number, the third calculator lets you enter separate local rates for base installation, site prep, reinforcement and decorative finish. This is especially useful when comparing bids because you can normalize each quote to the same project area.
Hawaii construction costs are influenced by the realities of building on islands. Cement, admixtures, equipment parts, reinforcement, form materials and specialty products may depend on marine freight and local inventory. Even when concrete itself is produced locally, the inputs that support batching and construction can be exposed to shipping schedules and import costs. A 2025 Hawaiʻi industry report noted that local suppliers were monitoring international sourcing and tariffs, although the reported tariff effect on ready-mix at that time was relatively small compared with total per-yard pricing.
Labor is another important cost layer. Hawaii's Department of Labor and Industrial Relations published Wage Rate Schedule Bulletin No. 510 on February 16, 2026 for public construction work under Chapter 104. It listed a prevailing total rate of $85.16 per hour for a journeyperson cement finisher, including a $46.83 basic hourly rate and $38.33 fringe rate. That is a public-works prevailing wage benchmark, not a private residential contractor price, but it demonstrates why labor-intensive concrete work can carry a substantial cost in Hawaii.
The examples below use the calculator's $350/yd³ planning material rate, a 10% material allowance and simple arithmetic. They are not contractor bids. Labor, delivery, pumping, reinforcement, grading and permits must be added separately.
| Project | Area | Thickness | Order with 10% | Concrete at $350/yd³ |
|---|---|---|---|---|
| 10 × 10 pad | 100 ft² | 4 in | 1.36 yd³ | ≈ $475 |
| 12 × 20 patio | 240 ft² | 4 in | 3.26 yd³ | ≈ $1,141 |
| 20 × 20 slab | 400 ft² | 4 in | 5.43 yd³ | ≈ $1,901 |
| 20 × 40 driveway | 800 ft² | 5 in | 13.58 yd³ | ≈ $4,753 |
| 24 × 40 slab | 960 ft² | 6 in | 19.56 yd³ | ≈ $6,844 |
Measure actual formed length and width or calculate the shape area.
Use the project design thickness, not a guess based only on price.
Area × thickness in feet gives cubic feet; divide by 27 for cubic yards.
Add a project-appropriate allowance for field variation and ordering.
Apply the supplier quote, delivery, pump, labor, prep and finish costs.
Then multiply by 1 + allowance percentage ÷ 100 to get the planned order quantity.
Not every concrete pour needs the same permit review. The City and County of Honolulu Department of Planning and Permitting states that projects not qualifying for an Instant Online Permit require plans, and certain work involving reinforced-concrete structural members may require stamped plans. Permit fees and other agency approvals can also apply depending on scope, grading, drainage, zoning, wastewater, flood hazard or special management area conditions.
For a structural slab, footing, retaining wall, driveway connection or building addition, verify the requirements with the authority having jurisdiction before assuming the calculator total is the full project cost. Concrete quantity is only one part of a code-compliant project.
Concrete price is only one layer. A realistic estimate adds the site, delivery and placement costs that surround the pour.
Longer haul distance and delivery zones can increase cost and scheduling complexity.
Strength, aggregate, admixtures and special performance requirements affect price.
Steep or tight sites may require pumping, smaller equipment or additional labor.
Stamped, colored, polished or specialty concrete costs more than a basic finish.
Rebar, welded wire reinforcement, dowels, thickened edges, grade beams and complex formwork add both material and labor. Do not assume the concrete price per yard includes these items unless the quote explicitly says so.
Removing an existing slab, hauling debris, excavating unsuitable soil, importing base material and compacting the subgrade can exceed the cost of the concrete itself on difficult sites. Hawaii's volcanic terrain and sloped lots can make preparation highly project-specific.
If the truck cannot discharge directly into the forms, a line pump or boom pump may be needed. Pump minimums, setup time, hose length, cleanup and crew coordination should be included as separate line items in the estimate.
Bagged concrete can be convenient for post holes, small steps, repairs and tiny pads because it avoids ready-mix minimums and truck scheduling. However, as volume grows, mixing dozens of bags becomes labor intensive and the effective material cost per cubic yard can become much higher.
Best for slabs, patios, driveways and larger pours where consistent batching and fast placement matter.
Best for small-volume work when the quantity is manageable and ready-mix delivery is impractical.
Use the Concrete Bags to Cubic Feet calculator to check bag yield, or the Concrete Bags to Cubic Yards calculator when comparing a small ready-mix order with bagged concrete.
For a complete project estimate, combine this Hawaii cost page with the site's quantity and conversion tools. Start with the Concrete Calculator for volume, use the Cubic Feet to Cubic Yards converter when a supplier quotes in yards, and use the Decorative Concrete Calculator for stamped, colored or sealed surfaces. If you are comparing regional budgets, see related location pages such as Concrete Cost in Arizona, Concrete Cost in Colorado and Concrete Cost in Connecticut.
This calculator is designed for budgeting, not quoting. The published examples use public or industry reference points available at the time of this page update. Always request a current supplier and contractor quote for your actual project.
