Quick Answer: Bagged concrete mix typically runs $5 to $10 per bag as of 2026, with standard 80 lb sack mix at the low end, high strength and fiber reinforced in the middle, and fast set and specialty blends at the top. The price you actually pay moves with mix design, bag weight, strength rating, and the regional market. Use the ranges below as a planning anchor, then pull current quotes from your suppliers for the bid date.
What Drives the Price
Mix design is the biggest single driver. A standard 4000 psi sack mix is the baseline product, it is a blend of Portland cement, sand, aggregate, and just enough chemistry for general purpose work, and it owns the low end of the range. High strength mixes (5000 to 6000 psi) carry a premium because they use more cement and better aggregate gradation, so they land 20 to 40 percent above the standard bag. Fast set mixes (like Quikrete Fast Setting and Rapid Set) use calcium based accelerators and specialty cements that cure in 20 to 45 minutes, which drives the price up another 30 to 60 percent. Specialty blends, crack resistant, fiber reinforced, high early strength, and flowable fill, each add their own premium for the additive package.
Bag weight and yield move the number too. An 80 lb bag yields about 0.6 cubic feet, a 60 lb bag yields about 0.45 cubic feet, and a 40 lb bag yields about 0.3 cubic feet. The 80 lb bag is the cheapest per cubic yard of yield, the 60 lb bag is easier to handle on a ladder or in tight spots, and the 40 lb bag is for repair and small pour work where the premium per yard is worth the convenience. Region and volume round out the drivers. Cement is energy intensive to make, so mill pricing moves with fuel and power costs, and freight from the plant to your market matters because bag mix is heavy and bulky. Volume buyers pull pallet pricing 10 to 25 percent below single bag retail, and a full pallet (typically 40 to 80 bags depending on weight) cuts the per bag price another 5 to 10 percent.
Typical Price Ranges by Type
These ranges cover material only, not labor, and are typical as of 2026. Add $1.50 to $4.00 per bag for mixing and placing on small jobs, less on production pours.
- Standard 4000 psi sack mix (80 lb): $4.50 to $7.00 per bag. Slabs, footings, posts, general purpose work.
- Standard 4000 psi sack mix (60 lb): $4.00 to $6.50 per bag. Same product, smaller yield, easier handling on small pours.
- High strength 5000 to 6000 psi mix: $7.00 to $10.00 per bag. Driveways, garage slabs, structural pours where higher psi is specified.
- Fast setting concrete mix: $8.00 to $12.00 per bag. Post holes, fence and deck posts, repairs where 20 to 45 minute set is needed.
- Crack resistant / fiber reinforced mix: $7.50 to $11.00 per bag. Slabs subject to shrinkage and traffic, with fibers and additives to control cracking.
- High early strength / Rapid Set class: $10.00 to $14.00 per bag. Repairs, DOT work, pours that need to open to traffic in hours.
- Lightweight and repair mixes: $8.00 to $13.00 per bag. Resurfacing, patching, vertical and overhead repair work.
Pallet pricing cuts the per bag price 10 to 25 percent on volume jobs. If your pour runs more than a few bags, ask for the pallet rate, the savings show up fastest on the standard 80 lb line.
How to Calculate the Quantity You Need
Bag mix takeoff is cubic feet of concrete divided by yield per bag. Calculate the pour volume in cubic feet (length times width times depth in feet, or area times thickness), then divide by the yield of your chosen bag: 0.6 CF for an 80 lb bag, 0.45 CF for a 60 lb bag, 0.3 CF for a 40 lb bag. For a 4 inch slab, one 80 lb bag covers about 1.8 square feet, so a 100 SF patio at 4 inches takes about 56 bags (100 / 1.8). Convert to cubic yards by dividing by 27 if your supplier quotes by the yard, which is common on pours above 1 to 2 cubic yards, where ready mix starts to beat bag mix on price.
Apply a 5 percent waste factor for slabs and flatwork, 10 percent for post holes and small pours where over dig and spill are common. Round up to the pallet to avoid partial pallet premiums, and add a separate line for any reinforcing (rebar, wire mesh, fiber) and any admix the spec calls for, because they are not in the bag price. Tie every quantity to the pour schedule on the takeoff sheet so the bid is defensible.
How to Buy Smarter
- Get three supplier quotes on the same mix, strength, and bag weight. Bag mix pricing varies 15 to 30 percent between distributors on identical spec.
- Quote each mix type on its own line. Mixing standard, high strength, and fast set into one line hides the real cost and lets a sub swap to a cheaper mix.
- Buy by the pallet on volume jobs. Single bag retail can be 25 percent above pallet pricing on the same product.
- Lock quotes for 30 to 60 days on longer bids. Bag mix moves with cement, fuel, and seasonal demand, so a stale quote is a losing quote.
- Specify the product by name, strength, and bag weight, not just "bagged concrete." A generic spec lets the low bidder substitute a 4000 psi bag where a 5000 psi was needed.
- Compare to ready mix above 1 to 2 cubic yards. Bag mix wins on small pours and repairs, ready mix wins on larger pours once delivery and minimum load fees are included.
Where Estimators Get It Wrong
The most common mistake is treating all bagged concrete as one line. A fast set bag costs double what a standard 4000 psi bag costs, so a single line with a blended price either overprices the slab or underprices the post work. The second mistake is confusing 60 lb and 80 lb yields. Estimators who assume 0.6 CF per bag on every pour lose money when the crew buys 60 lb bags that yield 0.45 CF. The third is forgetting reinforcing and admix. A slab spec with fiber, wire mesh, or a curing compound adds to the cost, and skipping them in the bid means eating the difference. The fourth is using retail box store pricing for the bid. Box stores carry a narrow selection at retail, while a building supply or masonry yard has pallet pricing 20 to 40 percent lower on the same mix. The fifth is underestimating waste on post holes and small pours. Over dig, spill, and uneven mixing can push waste past 10 percent on fence and deck work, so a 5 percent factor leaves you short.
Putting It Together
Build your bag mix line from the spec up: list each mix type separately, price it by the pallet at the right bag weight, and calculate bags from the pour schedule using real yield at the actual strength. Add reinforcing and admix on their own lines where the spec calls for them. Pull three current quotes and lock them for 30 to 60 days. Bag mix is a small line that leaks big money when it is mispriced, so a clean takeoff and separate lines per mix type are what keep the pour on grade and the margin in.
