Concrete Bag Calculator
Bags Needed by Size
| Bag Size | Yield | Bags/yd³ | Approx. Price | Best For |
|---|---|---|---|---|
| 40 lb | 0.30 ft³ | 90 bags | ~$4.50 | Small patches, limited mobility |
| 60 lb | 0.45 ft³ | 60 bags | ~$5.98 | Solo work, walkways, fence posts |
| 80 lb | 0.60 ft³ | 45 bags | ~$7.28 | Slabs, driveways — best value |
80 lb bags give the best value per cubic foot but require two hands and a strong back. 60 lb bags are the best balance of cost and manageability — one person can handle them comfortably all day. 40 lb bags are best for tight spaces, seniors, or anyone with back limitations. For large projects, 80 lb bags mean fewer trips and less mixing time.
Quikrete is the most widely available concrete bag brand in North America and offers the broadest product line — standard, fast-setting, high-strength, crack-resistant, and fiber-reinforced formulas. Sakrete is a comparable quality product common in the eastern U.S. Store-brand bags from Home Depot or Lowes are typically the same quality at a lower price. All produce a nominal 3000–4000 PSI mix.
Common Project Bag Count Answers
Buying and Storing Concrete Bags
An 80lb bag yields approximately 0.60 cubic feet of mixed concrete. A 60lb bag yields 0.45 cubic feet. A 40lb bag yields 0.30 cubic feet. These numbers are printed on every bag — always verify before purchasing because manufacturers vary slightly. When buying in quantity, ask for bags from the same production run to avoid color variation in the finished surface.
Store bags flat in a dry location off the ground. Concrete absorbs moisture through paper — bags stored on concrete floors or in humid conditions can partially set inside the bag within days. Always inspect bags for hard lumps before mixing. Return lumpy bags for fresh product — they produce weak concrete with poor workability.
🚛 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.
1:2:4 Mix Ratio — Bag Equivalent
When working from a mix ratio recipe instead of pre-mixed bags, here is what one cubic yard of 1:2:4 mix (2500 PSI) requires in raw materials:
- Portland cement: 6 bags (94 lbs each) — about 564 lbs total
- Sand: 1,170 lbs — about 0.6 cubic yards
- Gravel/aggregate: 1,740 lbs — about 0.9 cubic yards
- Water: 28-32 gallons (0.5 water-cement ratio by weight)
This produces approximately 1 cubic yard of finished 2500 PSI concrete suitable for footings and foundation walls. For a stronger 1:2:3 mix (3000 PSI), use 7 bags of cement instead of 6. Use our Concrete Mix Ratio Calculator for exact quantities of any volume.
