For projects under 1.5 yards, bagged concrete is almost always cheaper than ready-mix delivery (which charges short-load fees of $75–$200 below 3 yards).
Cubic Yards vs Cubic Feet vs Bags
1 cubic yard = 27 cubic feet. Picture a cube 3 feet on each side. That's a yard. It's the standard unit ready-mix suppliers use because it's how trucks are measured (a typical drum holds 9–11 yards).
1 cubic yard ≈ 45 bags of 80 lb concrete (each yields ~0.60 cu ft). Or about 60 bags of 60 lb (each yields ~0.45 cu ft). Or 90 bags of 40 lb (each yields ~0.30 cu ft).
When to order by the yard (ready-mix): 3+ cubic yards. The savings versus bags is significant once you hit a full delivery, and you save many hours of mixing labor.
When to order by the bag: Under 1 cubic yard, or for projects in tight spaces a truck can't reach (back yards, narrow side gates, tight side-yard footings). For 1–3 yards, run the cost both ways before deciding.
Ready-Mix vs Bags: The Real Break-Even
Bags every time. Ready-mix has a short-load fee of $75–$200 below 3 yards. 45 bags of 80lb at $6 each = $270 — far cheaper than the minimum delivery charge plus concrete cost.
Ready-mix wins on labor. Mixing 135+ bags by hand takes hours and wears you out before the pour begins. A standard truck load (9 yards) at $150/yard delivered costs $1,350 — vs 405 bags at $6 = $2,430 in materials alone before labor.
How Ready-Mix Concrete Delivery Works
A standard ready-mix truck carries 8–10 cubic yards. Most residential pours need 3–8 yards. Always order 10% more than your calculated amount — you cannot call for a second delivery mid-pour without a serious cold joint problem.
Ordering less than 3 yards typically triggers a short-load fee of $75–$200. If you need 2 yards, buying bags may be cheaper than paying the short-load surcharge. Use our calculator to compare options.
Trucks typically allow 7–10 minutes per yard for unloading. After that, overtime charges of $1–$3 per minute apply. Have your crew and tools ready before the truck arrives. Never let the driver wait.
Standard residential slab: 3,000 PSI. Driveway or garage floor: 3,500–4,000 PSI. Footings and foundations: 3,000–4,000 PSI. The higher the PSI the stronger and more expensive the mix. Specify PSI when you call — not all plants use the same default.
🚛 Truck Payload Reality Check
| 2026 Truck | Max Payload | Concrete Capacity | Bag Capacity (80lb) |
|---|---|---|---|
| Toyota Tacoma (standard) | 1,521 lbs | ~0.38 cu yd | ~18 bags |
| Toyota Tacoma (i-FORCE MAX) | 1,705 lbs | ~0.42 cu yd | ~21 bags |
| Ford F-150 (PowerBoost Hybrid) | 1,740 lbs | ~0.43 cu yd | ~21 bags |
| Ford F-150 (5.0L V8) | 2,235 lbs | ~0.55 cu yd | ~27 bags |
| Ford F-150 (3.5L EcoBoost) | 2,440 lbs | ~0.61 cu yd | ~30 bags |
| 3/4-ton (F-250, Silverado 2500) | 3,500+ lbs | ~0.87 cu yd | ~43 bags |
*Payload values from 2026 manufacturer specs. Your actual payload is on the door-jamb sticker. Add accessories (toolbox, bedliner) and that number drops 100-300 lbs. A driver and passenger count against payload too.
If your project needs more than 1 cubic yard (4,000 lbs), pickup-truck delivery requires multiple trips. For 2+ cubic yards, ready-mix delivery is almost always cheaper than the gas, time, and suspension wear of multiple bag runs. Most ready-mix trucks deliver 8-10 yards in one trip.
