Ready-Mix vs Bagged Concrete: Cost, Labor & Decision Guide
Detailed comparison of ready-mix truck delivery versus bagged concrete: costs per cubic yard, short-load fees, labor hours, PSI strength consistency, and project break-even points.
The decision between ready-mix truck delivery and bagged concrete depends on project volume: projects requiring under 1 cubic yard (45 eighty-pound bags) are usually cheaper with bagged concrete, while pours exceeding 1.5 to 2 cubic yards are cheaper, faster, and structurally more consistent with ready-mix concrete.
To determine your volume in cubic yards, use the Concrete Slab Calculator or check the Concrete Bag Yield Chart.
Direct Comparison Overview
| Factor | Bagged Concrete (DIY) | Ready-Mix Delivery (Truck) | Winner by Volume |
|---|---|---|---|
| Material Cost (Per Yard) | $250 – $320 / yd³ | $130 – $185 / yd³ | Ready-Mix (Bulk discount) |
| Short-Load Fees | None | $75 – $150 (if < 4 to 5 yards) | Bagged (< 1.5 yards) |
| Mixing Time (1 Yard) | 2.5 to 4.0 hours (Manual/Drum) | 10 to 20 minutes (Chute pour) | Ready-Mix |
| Physical Effort | High (lifting 3,600 lbs of dry sacks) | Low (direct placement via chute/buggy) | Ready-Mix |
| Strength Consistency | Variable (inconsistent water ratios) | High (automated batch plant ASTM C94) | Ready-Mix |
| Cold Joint Risk | High (slow consecutive batching) | Low (monolithic continuous pour) | Ready-Mix |
| Equipment Needed | Wheelbarrow, drum mixer, hoe | Chutes, wheelbarrows, bull float | Equal |
Detailed Cost Breakdown per Cubic Yard
One cubic yard equals 27 cubic feet. Achieving this volume requires forty-five 80-pound bags or sixty 60-pound bags.
Cost of Bagged Concrete for 1 Cubic Yard
- 45 bags of 80 lb standard mix (e.g., Quikrete/Sakrete at $6.20/bag): $279.00
- Sales tax (average 7%): $19.53
- Pickup truck fuel or store flatbed delivery fee: $45.00 – $79.00
- Electric cement mixer rental (optional, 1 day): $65.00
- Total Investment for 1 Yard: $343.53 – $442.53
Cost of Ready-Mix Concrete for 1 Cubic Yard
- Base concrete rate (4,000 PSI mix, 1 yard): $145.00
- Short-load fee (orders under 4–5 yards): $95.00 – $140.00
- Environmental & fuel surcharge: $25.00 – $40.00
- Total Investment for 1 Yard: $265.00 – $325.00
While ready-mix carries a short-load penalty on a single yard, its total price remains competitive with store-bought bags once delivery and rental mixer fees are factored in. At 3 cubic yards and above, ready-mix is decisively cheaper.
Cost Comparison by Project Size
The table below illustrates total material expenses across common home improvement projects:
| Project Size | Equivalent 80 lb Bags | Total Bagged Cost ($6.20/bag) | Ready-Mix Cost (with Delivery) | Recommended Choice |
|---|---|---|---|---|
| 0.5 Cu Yd (2 fence posts) | 23 bags | $142.60 | $260.00 (Minimum truck run) | Bagged Concrete |
| 1.0 Cu Yd (4′×10′ walkway, 4″) | 45 bags | $279.00 | $295.00 (Includes short-load) | Tie / Bagged |
| 2.0 Cu Yds (12′×12′ patio, 4″) | 90 bags | $558.00 | $360.00 – $410.00 | Ready-Mix |
| 4.0 Cu Yds (20′×20′ patio, 4″) | 180 bags | $1,116.00 | $620.00 – $720.00 | Ready-Mix |
| 7.0 Cu Yds (24′×24′ 2-car garage, 5″) | 315 bags | $1,953.00 | $1,050.00 – $1,200.00 | Ready-Mix |
Structural Quality and Technical Differences
Cost is only one dimension. The structural integrity of the final slab differs substantially between the two methods:
1. Water-Cement Ratio and Strength (f′c)
The ultimate compressive strength of concrete is governed by the water-cement (w/c) ratio. A water-cement ratio between 0.40 and 0.45 yields 4,000+ PSI concrete.
- In ready-mix plants, computer sensors measure moisture in sand and aggregates, adding exact water quantities per ASTM C94 specifications.
- In manual wheelbarrow mixing, DIYers routinely add excess water (soup-like consistency) to make the mix easier to shovel. Adding just one extra gallon of water per sack can reduce 28-day compressive strength by up to 40% and increase surface cracking.
2. Cold Joints
Concrete begins setting within 45 to 90 minutes. When mixing 90 bags in a single wheelbarrow or small 3.5 cu ft drum mixer, batching takes 4 to 6 hours. The first batches stiffen while later batches are placed against them, creating internal fault lines known as cold joints. Ready-mix trucks discharge 5 to 10 cubic yards in 20 minutes, allowing a monolithic pour that cures uniformly.
Decision Matrix: Which Should You Choose?
Choose Bagged Concrete When:
- Total volume is under 1 cubic yard (under 40 to 45 bags). Examples include mailbox posts, fence posts, deck footings, and small equipment pads.
- Access is severely restricted. If your backyard cannot accommodate a concrete truck or a mini-buggy and pumping is cost-prohibitive, bags carried by hand may be the only feasible option.
- Pours are phased over multiple weekends. If you are casting individual footings over weeks rather than in one pour.
Choose Ready-Mix Concrete When:
- Total volume exceeds 1.5 to 2.0 cubic yards. Mixing 90 bags of concrete means moving 7,200 pounds of dry aggregate and adding 400 gallons of water by hand.
- Surface finish and appearance matter. Driveways, garage floors, and decorative stamped patios require uniform color, consistent slump, and uninterrupted troweling.
- Structural engineering specifications apply. Commercial slabs, foundation grade beams, and retaining walls requiring 3,500 to 5,000 PSI certified mix tickets.
Frequently Asked Questions
What is a concrete short-load fee?
Ready-mix dispatchers charge a short-load fee (typically $75 to $150) when ordering less than their minimum batch threshold, usually 4 to 5 cubic yards. This fee covers the cost of sending a 30-ton commercial vehicle to a residential site with a small load.
How long do you have to unload a ready-mix truck?
Standard ready-mix contracts provide 5 to 7 minutes of free unloading time per cubic yard (roughly 30 to 45 minutes for a 5-yard load). Exceeding this window incurs standby detention fees of $2.00 to $3.50 per minute. Have your forms oiled, subbase compacted, and a crew of at least 3 people ready before the truck arrives.
How many 80 lb bags can you mix in a standard wheelbarrow?
A standard 6-cubic-foot contractor wheelbarrow comfortably accommodates one to two 80-pound bags. Attempting to mix three bags causes dry aggregate spillage during hoed mixing.
Can you mix ready-mix and bagged concrete in the same pour?
It is not recommended. Bagged concrete and ready-mix use different aggregate sizes, moisture contents, and cement formulations. If you run short on a ready-mix pour, filling the remainder with bagged concrete often causes noticeable color variations, shrinkage cracks, and a weak cold joint at the interface.
