Bagged vs Ready-Mix Concrete: Which Is Cheaper?

The short answer

Bags win under about 1 to 2 cubic yards; the truck wins above it. Bagged concrete costs roughly $225 to $315 per cubic yard in materials alone (45 eighty-pound bags at $5–$7 each), while ready-mix typically runs $125 to $195 per yard delivered (typical 2026 US) — but small truck orders carry a $50 to $200 short-load fee. Fence posts and small pads: buy bags. A driveway: call the plant. A 12×12 patio at 4 inches (1.78 yards)? That is the gray zone — and this guide settles it.

Cost per cubic yard, head to head

One cubic yard needs 45 eighty-pound bags (27 cu ft ÷ 0.60 cu ft yield per bag). Multiply by your local bag price:

Every bag option costs 1.5× to 2× more per yard than ready-mix in materials alone — and that is before the labor. The only reason bags ever win is the delivery side: no truck minimums, no short-load fees, no scheduling. For a full breakdown of bag counts and yields, see the concrete bag calculator and the guide on how many bags of concrete per cubic yard.

The break-even chart by project size

Rules of thumb that hold across most US markets:

Why does the truck lose at small volumes? The short-load fee: most plants add $50 to $200 to orders under roughly 4 yards, because they are still sending a full mixer and driver for a half-empty drum. A 1-yard order at $160/yard plus a $120 short-load fee is really $280 for that yard — and suddenly bags are competitive again. Always ask the plant for its short-load threshold and its fee before you decide.

The labor math nobody shows you

An 80-lb bag takes roughly 5 minutes to mix, pour, and place by hand with a wheelbarrow mixer — and that is when you are fresh. Eighty bags is 400+ minutes of heavy labor: a full brutal day, with the first batches going off while you are still mixing the last (those are called cold joints, and they are weak points). A ready-mix truck pours a patio in about 20 minutes. Even if bags were the same price as the truck, your back gets a vote.

Quality: the hidden truck advantage

Plant-mixed concrete is batched by weight and computer, so every cubic yard is the same mix — the same strength, the same workability. Hand-mixed batches vary: a splash more water here, a short bag there, and one section of the slab cures weaker than the rest. For footings, structural slabs, and anything an inspector looks at, uniformity alone justifies the truck. For a stepping stone or a mailbox post, nobody cares.

Worked example: a 12 × 12 ft patio at 4 inches

Volume: (12 × 12 × 0.333) / 27 = 1.78 cubic yards. The bag route: 1.78 × 45 = 80 bags of 80-lb mix — at $6 each, $480 in materials plus a full day of mixing, hauling 6,400 lbs of bag weight, and a sore everything. The truck route: 1.78 × $160 = $285, plus a short-load fee of, say, $100 → ~$385 total, poured in 20 minutes with uniform strength. The truck wins this one by about $95 and a weekend. (These are typical 2026 US figures — plug your own bag price and plant quote into the calculator.)

If you go the bag route: rent the mixer

Hand-mixing in a wheelbarrow caps you at that 15-to-25-bag day. An electric drum mixer — typically $40 to $60 a day to rent — roughly doubles your pace and, more importantly, keeps batches consistent: same water, same mix time, same strength. Mix each batch 3 to 5 minutes (undermixed concrete is weak; overmixed concrete loses workability), and pour each batch before the previous one goes off so the layers knit instead of forming cold joints. For anything over about 40 bags, two people is the minimum crew — one mixing, one placing — or the mixer outruns the wheelbarrow and the whole day turns into a race against the set.

What the plant asks when you order

If you go ready-mix, the dispatcher needs four things: the volume in cubic yards (add 5–10% waste — forms are never perfect), the mix strength (4,000 psi is the common residential spec for slabs and driveways; 3,000 psi for footings and fence posts), the slump (4 inches is standard; higher slump is more workable but weaker — never let the driver add water freely on site), and your delivery address and access notes. Schedule the truck for after your forms, rebar, and crew are 100% ready. A mixer that waits on you accrues waiting-time charges, and concrete waits for no one.

When the truck can't reach you

Some sites defeat the mixer: long setbacks, soft ground, or a backyard patio behind the house. Options, in order of cost: have the truck chute it as far as the 12–16 ft chute reaches and wheelbarrow the rest (fine for 1–2 yards); rent a concrete buggy (powered wheelbarrow) for longer hauls; or hire a line pump for big or awkward pours — typically a few hundred dollars, worth it when the alternative is forty wheelbarrow trips. None of these change the bags-vs-truck math, but they are the difference between a plan and a disaster on pour day.

Decision checklist

Go with bags if: the job is under ~1 yard; the site has no truck access; you are doing fence posts or a small repair and want to finish in an afternoon. Go with ready-mix if: the job is over ~2 yards; the slab is structural or inspected; you value your spine. In the gray zone (1–3 yards): call the plant for the delivered price including the short-load fee, price the bags at your store, and be honest about the labor. If the plant number is within a couple hundred dollars of the bag number, the truck wins on time and quality.

Common mistakes

Ordering a full truck for 1 yard. The short-load fee turns cheap concrete expensive — run the all-in number. Mixing bags for a driveway. A 10×20 ft driveway at 4 inches is 2.47 yards: 111 eighty-pound bags. Do not. Forgetting the short-load fee in the comparison, then being surprised at checkout. Underestimating hand-mixing time. Plan on 15 to 25 bags a day, max, with cold joints between days. No backup plan for leftover concrete. Trucks come in whole-yard increments; have a form ready for the overage — a stepping stone, a pad, something.
