Bagged vs Ready-Mix Concrete Cost Comparison by Project Size
Bagged concrete is cheaper for anything under 1.5 cubic yards. Ready-mix wins above 2 yards. The crossover is lower than most people expect — a 12×16 patio at 4 inches sits right at the break-even point. For small slabs and footings, skip the truck entirely. For anything driveway-sized, mixing bags yourself costs more in materials and takes a full day of labor.
Before comparing costs below, calculate concrete yardage for a slab to find your exact cubic yardage. For background on how these two options differ beyond cost, see our ready-mix vs bagged concrete comparison.
Quick Reference
| Project Size | Volume | Cheaper Option | Why |
|---|---|---|---|
| Small pad / footing | Under 0.5 yd³ | Bagged | No minimum, no delivery fee |
| Shed base / small patio | 0.5–1.5 yd³ | Bagged | Delivery fees still dominate |
| Medium patio / walkway | 1.5–2 yd³ | Roughly equal | Get a local quote |
| Standard driveway section | 2–5 yd³ | Ready-mix | Per-yard rate drops sharply |
| Full driveway / garage floor | 5+ yd³ | Ready-mix | Always — bagging is impractical |
The Cost Crossover: Where Bagged Stops Winning
The crossover between bagged and ready-mix concrete falls around 1.5–2 cubic yards for most U.S. markets. Below this threshold, ready-mix minimums and delivery fees push the per-yard cost above bagged material. Above it, ready-mix material cost per yard is roughly 30–50% lower.
| Cubic Yards | Approx. Slab Size (4" thick) | Bagged Cost (materials only) | Ready-Mix Cost (delivered) | Cheaper Option |
|---|---|---|---|---|
| 0.5 yd³ | 6×9 ft | $140–200 | $350–500 (minimum charge) | Bagged |
| 1.0 yd³ | 9×12 ft | $280–400 | $350–500 (minimum) | Bagged |
| 1.5 yd³ | 11×15 ft | $420–600 | $380–550 | Roughly equal |
| 2.0 yd³ | 13×17 ft | $560–800 | $400–600 | Ready-mix |
| 3.0 yd³ | 16×20 ft | $840–1,200 | $520–750 | Ready-mix |
| 5.0 yd³ | 20×25 ft | $1,400–2,000 | $700–1,000 | Ready-mix |
| 8.0 yd³ | 26×33 ft | $2,240–3,200 | $1,040–1,440 | Ready-mix |
Regional note: Ready-mix prices vary 20–40% by market. Short-load fees and minimum order thresholds also differ by supplier. Always get a quote before assuming the table above matches your local numbers. Use the concrete cost per square foot guide for regional benchmarks.
Bagged Concrete Cost Breakdown
Bagged concrete pricing is straightforward: you pay retail per bag, plus sales tax. There are no minimums, no delivery fees, and no scheduling constraints.
Standard bag sizes and yields:
| Bag Weight | Yield | Retail Price | Cost per Cu Yd |
|---|---|---|---|
| 40 lb | 0.30 cu ft | $4–6 | $370–550 |
| 60 lb | 0.45 cu ft | $5–8 | $330–520 |
| 80 lb | 0.60 cu ft | $6–9 | $280–420 |
The 80 lb bag is almost always the cheapest per cubic yard. Use 40 or 60 lb bags only when you can't physically handle 80s.
Hidden costs with bagged concrete:
- Mixer rental: $60–90/day for a drum mixer (required for anything over 0.5 yards if you want consistent mix)
- Labor time: 4–8 hours of hard physical work per yard
- Bag disposal: most municipalities charge for concrete bag waste
For a project requiring 1 yard (27 bags × 80 lb), expect to spend 3–4 hours mixing and placing concrete with one helper. See the how many bags guide for an exact bag count for your slab dimensions.
Ready-Mix Concrete Cost Breakdown
Ready-mix pricing has two components: the per-yard rate and any additional charges for small orders, short notice, or remote delivery locations.
Typical ready-mix pricing (2025–2026, national averages):
| Order Size | Per-Yard Rate | Short-Load Fee | Typical Total |
|---|---|---|---|
| Under 1 yd³ | $170–220 | $150–300 | $350–550 |
| 1–3 yd³ | $155–200 | $50–150/partial yd | $350–700 |
| 3–5 yd³ | $140–180 | None or minimal | $450–900 |
| 5–10 yd³ | $130–165 | None | $650–1,650 |
| 10+ yd³ | $120–155 | None | $1,200+ |
Additional charges to ask about:
- Saturday delivery surcharge: $50–100
- Concrete pump rental: $300–600 (required when the truck can't reach the pour site)
- Excess concrete return fee: typically charged if you order significantly more than you pour
- Waiting time fee: $1–3 per minute after the first 5–8 minutes of unloading time
For projects requiring a pump truck, costs shift significantly — see the bagged vs ready-mix vs pump truck guide for a three-way cost comparison.
Project-Size Decision Guide
Under 0.5 cubic yards (small pads, footings, post holes)
Bagged concrete is the clear choice. You can carry 10–15 bags in a standard vehicle, mix by hand in a wheelbarrow, and avoid scheduling headaches. A 4×6 shed footing pad uses about 0.25 yards — roughly 12 bags. Material cost: $70–110.
0.5–1.5 cubic yards (small patios, garden paths, shed bases)
Bagged concrete still wins on cost, but a drum mixer becomes worth renting. At this scale, mixing by hand leads to fatigue-driven errors. Rent a mixer, have a helper, and plan for a full day. Material cost for 1 yard: $280–400 bagged versus $350–500 for a ready-mix minimum.
1.5–3 cubic yards (average patio, small driveway section, walkways)
This is the decision zone. Get a ready-mix quote from a local plant and compare to bagged materials. If the ready-mix quote (including short-load fees) is within $100–150 of bagged material cost, choose ready-mix — the labor savings and quality consistency are worth the difference.
3–8 cubic yards (standard driveway, large patio, garage floor approach)
Ready-mix is almost always the right call. The per-yard rate drops, there are no short-load fees, and bagging this volume requires 6–10+ hours of mixing labor with multiple people. A 20×20 driveway (roughly 5 yards at 4 inches) runs $700–1,000 delivered versus $1,400–2,000 in bagged materials alone — before counting labor or mixer rental. See the DIY vs contractor guide for how labor changes the full cost picture.
Over 8 cubic yards (full driveways, garage floors, large pads)
Always use ready-mix. At this scale, bagging becomes physically impractical and the cost premium is significant. Focus instead on optimizing your ready-mix order: minimize short-load fees by ordering accurately, and have your forms and crew ready before the truck arrives to avoid waiting-time charges.
The True Cost Comparison: Include Labor
Material cost alone understates the bagged concrete premium on medium projects. Include labor when comparing options:
The material tables above make bagged concrete look competitive through 2 yards. Add labor and the picture changes. Concrete is one of the most physically demanding materials to mix by hand — a yard of bagged concrete is 45 bags of 80 lbs. At one yard, that's manageable. At three yards, it's a full day of exhausting work with a helper, and fatigue-driven water-ratio errors are the most common cause of weak DIY concrete.
Labor cost of bagged concrete (per yard mixed):
- Your time: 3–4 hours per yard (valued at any wage rate you choose)
- If hiring labor: $30–60/hour × 3–4 hours per yard = $90–240/yard in labor
At $15/hour personal time value, a 3-yard bagged project adds $135–180 in labor cost. At market wages for a helper, it adds $270–720. In either case, ready-mix starts looking very competitive once projects exceed 2 yards.
Ready-mix labor advantage: A 3-yard pour with ready-mix takes 2–3 hours total for a crew of two (form setup already done). The same 3 yards in bags takes a full day for the same crew.
Key Takeaways
- Bagged wins under 1.5 yards — no minimums, no scheduling, no delivery fees.
- Ready-mix wins over 2 yards — lower per-yard cost, no mixing labor, consistent quality.
- The 1.5–2 yard range is the decision zone — get a local ready-mix quote and compare directly.
- Always factor in labor — on medium projects, mixing labor often exceeds the material cost difference.
- Short-load fees are the key variable — ask your local plant for their minimum order and short-load policy before deciding.
