How Many Bags of Concrete Make a Yard?

Bags per yard by bag size

Every bag publishes a yield, which is how much wet concrete it makes. A cubic yard is 27 cubic feet, so bags per yard is 27 divided by the yield.

Those yields are from Quikrete's data sheet for Concrete Mix No. 1101, and Sakrete publishes the same figures for its equivalent product. Flip the chart around and one 80 lb bag makes about 0.022 cubic yards, which is next to nothing. That is why a modest-looking slab turns into a stack of 40 bags.

Notice the last column. Whichever size you buy, a cubic yard of concrete is 3,600 lb of dry mix, because every published yield works out to exactly 0.0075 cubic feet per pound. The bag size changes how many trips you make, not how much you carry.

How many bags on a pallet, and does a pallet make a yard?

Short answer to the second question: no, and it is the most useful thing on this page. Every standard pallet configuration lands between 0.875 and 0.933 cubic yards. You are 7 to 13 percent short, and the error always runs in the expensive direction, because you find out when the truck is gone and the forms are half full.

The counts come from the places that actually sell pallets: Home Depot lists a 42-bag pallet of 80 lb concrete mix and a 56-bag pallet at 60 lb, and Quikrete's own QUIKRETE 5000 page states "60 lb. bags - 56 per pallet, 80 lb. bags - 42 per pallet." Distributor listings for Sakrete, Amerimix, Spec Mix and Basalite use the same counts, so this is not brand-specific.

Why the counts look arbitrary and are not

Run the net weights: 3,200, 3,200, 3,360, 3,360, 3,150. Manufacturers pack to a target pallet weight of roughly 3,200 pounds, not to a target number of bags. The bag count is whatever divides into that. Once you see it, the numbers stop needing to be memorized.

It also explains the commonest error in circulation. You will read that 80 lb bags come 56 to a pallet. They do not, they come 42. Fifty-six is the 60 lb count, and the two get swapped because 42 × 80 and 56 × 60 are both exactly 3,360 lb. Identical pallet, different bags.

The one exception

Lightweight high-yield mixes break the pattern in a useful direction. Sakrete Maximizer comes 35 bags to a pallet rather than 42, because the bags are the same weight but the mix is less dense. Sakrete states it yields 3 sq ft at 4 inches deep, which is 1.0 cubic foot per 80 lb bag against 0.60 for standard mix. So that pallet holds 17 percent fewer bags and makes about 1.3 cubic yards, the only common configuration that clears a yard. If you are buying by the pallet, that difference is worth more than the price per bag.

What a pallet weighs, and whether you can move it

Add the pallet itself, which runs 35 to 60 lb depending on species and moisture, and a full pallet of any bag size is roughly 3,200 to 3,400 lb, about 1.6 tons. That is past the payload rating of essentially every half-ton pickup, and of a diesel three-quarter-ton crew cab, where the engine eats several thousand pounds of the rating. Ford publishes a best-in-class maximum of 2,440 lb for the 2026 F-150, so a pallet is 1.38 times that; a stripped gas F-250 is rated far higher and would carry one. A pallet is a forklift item, not a pickup item, and the practical answer for a homeowner is either delivery or buying bags a few at a time.

Worth knowing that bags per pallet is not standardized by anyone. It is a manufacturer packing decision, which is why Quikrete publishes a count on its mortar, sand mix and 5000 pages and publishes none at all for its flagship Concrete Mix. The pallet footprint is standardized, at 48 by 40 inches, under ANSI MH1; the number of bags on it is not. Check the pallet placard rather than trusting a listing, since even retailer titles get it wrong: one big-box pallet SKU is titled as 64 bags of mortar while the bundle contents on the same page show 56.

Why the yields are what they are

Something worth noticing about the yield column. Multiply each one out: 0.30 × 90 = 27.0. 0.45 × 60 = 27.0. 0.60 × 45 = 27.0. Every published bag yield is an exact divisor of 27 cubic feet, and every data sheet says "approximately."

These are design values, not measurements. That does not make them wrong. Check the density: 80 lb of dry mix plus about 3.5 quarts of water is roughly 87 lb, over 0.60 cubic feet, which works out to about 145 lb per cubic foot, correct for normal weight concrete. The numbers are internally sound. They are just clean by construction rather than by measurement, which is a good reason to buy a spare bag rather than trusting the last one in the count.

The other reason to buy a spare is that the ground takes more than the plan says. Concrete coverage goes through why, including the tolerance that lets a legally graded subgrade sit three quarters of an inch low.

Bags or a ready-mix truck?

This is the real question behind the search, and the honest answer is that the crossover is lower than most people think, and it is set by labor rather than by price.

• Under about half a yard. Bags win outright. No delivery charge, no short-load fee, no minimum, and you mix at your own pace. Fence posts, a small pad, a mailbox.
• Half a yard to a full yard. Genuinely close, and worth pricing both ways.
• Over a yard. The truck almost always wins, on cost and on effort.

Put numbers on it. At typical shelf prices, 45 × 80 lb bags is well over $300 of material before you have mixed anything. The ready-mix industry's own benchmarking puts the average selling price at $160 per cubic yard, and delivered to a house most people pay $125 to $195. The material almost always favors the truck once you pass a yard.

What pushes the crossover back up is the delivery charge and the short-load fee on a small order. Published supplier schedules set the short-load threshold at three to seven yards depending on market, with the fee usually a flat $100 to $300 rather than a per-yard penalty. Ready-mix delivery has the real fee schedules.

And the labor is the part nobody prices. Forty-five bags is most of a day for two people, a rented mixer, and 3,600 lb lifted twice, once into the mixer and once into the forms. Bags also win regardless of arithmetic when access decides it: a back garden a truck cannot reach, or a pour you want to do in stages. How to mix concrete covers doing it properly once you have decided.

One number does not fit every bag

The chart at the top is for standard concrete mix. Change product and the yield moves, sometimes a lot:

• Sand and topping mix yields about 0.66 cubic feet per 80 lb bag rather than 0.60, so a yard is 41 bags rather than 45.
• High-yield lightweight mixes can reach 1.0 cubic foot per 80 lb bag, which takes a yard down to 27 bags.
• Fast-setting mixes are commonly sold in 50 lb bags, so the count changes even when the yield per pound does not.
• Mortar and sand mix are not concrete and are not interchangeable with it for a slab, whatever the bag count says.

Always read the yield printed on the bag you are actually buying. For the brand-specific tables, see Quikrete yield per bag and which Quikrete mix to use.

Estimate your own bag count

Bag counts scale with your exact volume, so the fastest route is to measure the pour and let the concrete bag calculator return the count in each bag size. If the answer comes back over a yard, the concrete yardage calculator gives you the number to hand a supplier instead.
