Home Depot concrete mix typically costs about $5-$9 per 60-pound bag and $6-$11 per 80-pound bag, with specialty mixes priced higher. A small repair may cost under $50 in materials, while a 10-by-10-foot slab can require roughly $250-$600 in bagged mix before labor, forms, tools, or delivery. Mix type, bag size, project thickness, and local store pricing drive the estimate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 60-lb standard concrete mix | $5 per bag | $7 per bag | $9 per bag | Usually yields about 0.45 cu ft |
| 80-lb standard concrete mix | $6 per bag | $8 per bag | $11 per bag | Usually yields about 0.60 cu ft |
| Fast-setting or specialty mix | $7 per bag | $10 per bag | $18 per bag | Price depends on formula and package size |
| Small DIY project materials | $25 | $100 | $350 | Mix only; excludes tools and site preparation |
| 10-by-10-ft slab, 4 in. thick | $250 | $400 | $600 | About 56-60 80-lb bags, plus waste allowance |

Home Depot concrete mix price by bag size and type
Common-purpose concrete mix is generally the lowest-cost choice for sidewalks, small pads, fence posts, and repairs. A 60-pound bag often sells for about $5-$9, while an 80-pound bag commonly runs $6-$11. The larger bag usually offers a lower cost per cubic foot, but it is heavier to carry and mix.
Fast-setting concrete mix often costs roughly $7-$18 per bag, depending on size and brand. It can be useful for setting posts or completing small repairs quickly, but a faster set leaves less time to place and finish the mix. Mortar mix, sand mix, and concrete repair products are not interchangeable with standard concrete; their prices and intended uses differ.
For routine small pours, budget about $7-$11 per 80-pound bag of standard concrete mix. Specialty products and smaller packages can raise the per-cubic-foot price. Check the package yield rather than comparing only the sticker price, since different bag weights produce different amounts of concrete.
| Mix category | Typical price | Typical yield | Common use |
|---|---|---|---|
| 60-lb standard mix | $5-$9 per bag | About 0.45 cu ft | Small repairs and posts |
| 80-lb standard mix | $6-$11 per bag | About 0.60 cu ft | Small slabs and walkways |
| Fast-setting mix | $7-$18 per bag | About 0.4-0.6 cu ft | Posts and quick repairs |
| Crack or patch product | $8-$30 per package | Varies by product | Surface repair, not full-depth pours |
What bagged concrete quotes include beyond the mix
The concrete bags are only one part of a project estimate. A small pour may also require lumber for forms, stakes, gravel for a base, reinforcement, a mixing tub or wheelbarrow, and finishing tools. Buying tools can make a one-time job notably more expensive than the bag price suggests.
For a basic DIY slab, materials other than concrete can add $40-$250, depending on dimensions and what is already available. A contractor quote may include labor, site preparation, forming, placement, cleanup, and disposal. Professional labor is often billed as a project amount or at roughly $50-$100 per worker-hour, with minimum charges for small jobs.
Ask whether an estimate includes base preparation, reinforcement, forms, delivery, and cleanup. A low quote that covers only concrete placement may not be comparable with a complete installed price.
| Quote item | Typical DIY cost | Typical installed or service cost | Price basis |
|---|---|---|---|
| Concrete mix | $6-$11 | Included or marked up | Per 80-lb bag |
| Forms and stakes | $20-$100 | $50-$250 | Small slab allowance |
| Gravel base | $25-$100 | $100-$400 | Delivery and quantity affect total |
| Reinforcement | $20-$150 | $50-$300 | Mesh or rebar, project dependent |
| Labor | $0 in hired labor | $50-$100 per worker-hour | May include minimum service charge |
| Delivery or disposal | $0-$100 | $50-$300 | Distance, load, and debris dependent |
How bag weight, mix strength, and slab depth change price
Volume is the biggest pricing driver. A 4-inch-thick slab uses about one cubic foot of concrete for every 3 square feet of surface area. For a 100-square-foot slab, that is about 33.3 cubic feet before extra material for uneven ground, spillage, or measurement error. At roughly 0.60 cubic feet per 80-pound bag, the order is around 56 bags; a 5%-10% cushion brings it to about 59-62.
Thickness changes the count proportionally. A 6-inch slab takes 50% more concrete than a 4-inch slab over the same footprint. If the slab needs a higher-strength mix, fiber reinforcement, or a special setting time, the product may cost more per bag. Follow the project design and package instructions rather than choosing strength solely by price.
Calculate cubic feet first, then divide by the bag’s stated yield and add about 5%-10% for waste. For a 4-inch slab, use square footage multiplied by 0.333 to estimate cubic feet; for 6 inches, multiply by 0.5. This estimate does not replace an engineered design for structural or load-bearing work.
Site access can also affect the finished quote. Carrying bags up stairs, moving them through a narrow gate, or hauling them a long distance from a vehicle takes more labor. A remote or uneven work area may require extra base material and more preparation than a level, accessible site.
Three Home Depot bag-mix project budgets by size
These examples use standard 80-pound bags at an estimated $6-$11 each and allow roughly 5%-10% extra mix. They exclude sales tax and assume the site is accessible, the ground needs only ordinary preparation, and no unusual reinforcement or demolition is required.
| Project | Mix estimate | Mix cost | Other likely materials | DIY material total |
|---|---|---|---|---|
| Two fence posts | 4-6 bags | $24-$66 | $10-$40 | $35-$110 |
| 4-by-4-ft pad, 4 in. deep | 10-12 bags | $60-$132 | $40-$140 | $100-$270 |
| 10-by-10-ft slab, 4 in. deep | 59-62 bags | $354-$682 | $100-$400 | $450-$1,080 |
Bagged concrete works best economically when the volume is modest and the work can be completed without a large crew. The 10-by-10-foot example can cost substantially more at the upper end if premium mix, extensive reinforcement, or extensive base work is needed. A hired installer adds labor and may use a different supply method.
Bagged concrete versus ready-mix truck delivery
Bagged mix has a low purchase threshold: buyers can get only the number of bags needed, transport them in stages, and avoid a truck minimum. Its drawback is the time and physical effort required to mix each batch. For a small post, step, or repair, those trade-offs often make bags practical.
Ready-mix concrete is commonly quoted by the cubic yard, with broad delivered pricing around $125-$200 per cubic yard before charges for short loads, difficult access, or special mixes. A truckload may also have a minimum order or delivery fee, so a small pour can carry a disproportionate charge. For larger pours, a local supplier quote is essential because delivery terms vary.
Compare the complete delivered price, not the per-bag price against the truck’s per-yard rate. An 80-pound bag yields about 0.022 cubic yard, so roughly 45 bags make one cubic yard, before waste. At $6-$11 each, that is about $270-$495 in bags alone, making ready-mix potentially cheaper for larger volumes if delivery minimums are manageable.
For work requiring several cubic yards, consistent placement, or a narrow finishing window, ready-mix can reduce mixing labor and improve continuity. For projects below about one cubic yard, bagged mix may avoid fees that outweigh its higher unit cost. Ask suppliers about minimums, waiting time, chute reach, and any short-load surcharge.
How long hand mixing takes and what hired labor adds
One person may spend roughly 5-10 minutes mixing and placing an 80-pound bag, excluding setup, moving the bag, water measurement, and finishing. That makes a 4-by-4-foot pad a manageable multi-batch task for a prepared DIYer; a 10-by-10-foot slab could require several hours of repeated mixing and coordinated placement.
For hired work, a small-job minimum can matter more than the hourly rate. A contractor may charge a few hundred dollars for a short visit, while a more involved slab can carry $500-$2,000 or more in labor depending on excavation, forms, reinforcement, access, and finishing. These are planning ranges, not uniform national rates.
Labor rises quickly when the pour requires many separate batches or must be finished continuously. Before accepting an estimate, clarify the crew size, included work hours, and whether site preparation and cleanup are included. For a slab that is too large to mix and place steadily by hand, a truck delivery or professional crew can prevent delays between batches.
Why concrete mix prices differ by store and region
Home Depot pricing can vary by ZIP code, store inventory, brand, package size, and promotion. Local construction demand and freight costs can affect retail prices, while regional labor rates have an even larger effect on installed totals. A quote in a high-cost metro area may run about 10%-25% above a comparable project in a lower-cost rural market, especially where labor and delivery are involved.
Delivery is also location-specific. Some stores offer local delivery for building materials, but fees depend on distance, order size, vehicle requirements, and access. A small bag order may be cheaper to collect in a suitable vehicle; dozens of 80-pound bags can make delivery worth comparing, even if the fee adds $50-$150 or more.
Use the local store’s current price and delivery quote when budgeting, rather than relying on a national average. Check the price for the exact bag weight and formulation, then compare the total needed quantity. Online listings may show a different price or availability from the nearby store.
How to lower a bagged-concrete budget without cutting quality
Measure the form dimensions carefully and calculate the required volume before buying. A 10%-15% over-order may be sensible where the base is uneven, but excessive extra bags create avoidable expense and heavy returns. Buy a modest allowance based on the actual site rather than rounding the estimate up by several full layers of bags.
Choose standard mix when its specifications suit the project. Fast-setting formulas can save time for isolated posts, but are usually unnecessary for a slab that needs normal placement and finishing time. Compare package yield and price per cubic foot across available bag sizes; a larger bag can lower unit cost if it can be safely handled and fully used.
The most controllable savings usually come from accurate quantity planning, suitable mix selection, and a clear scope. Prepare the area, forms, tools, and water before mixing starts so paid labor is not spent on avoidable delays. For a large pour, compare a delivered ready-mix quote with the total bag, delivery, equipment, and labor expense. Do not reduce required depth, reinforcement, or strength just to lower the estimate.
Request itemized quotes if hiring a contractor, and compare the same dimensions, thickness, finish, base preparation, and cleanup. A lower price may exclude excavation, disposal, or reinforcement. For a small project, also compare tool rental or borrowing with buying tools that may not be used again.
