Estimating Premixed Bagged Concrete
For small patios, fence posts, and minor repairs, hauling bulk ready-mix isn't feasible. Bagged concrete (sold in 40 lb, 50 lb, 60 lb, and 80 lb sizes) is mixed on-site. Knowing your precise cubic yard requirements allows you to directly translate the volume into the exact bag count needed at the hardware store.
Core Formula
Bag Count = Total Cubic Yards Required ÷ Yield per Bag (yd³)
Frequently Asked Questions
- How many 80 lb bags make a cubic yard?
- It takes exactly 45 bags of 80 lb concrete to produce one cubic yard of wet concrete (assuming a yield of 0.60 cubic feet per bag).
- How many 60 lb bags make a cubic yard?
- It takes exactly 60 bags of 60 lb concrete to produce one cubic yard (assuming a yield of 0.45 cubic feet per bag).
- Is it cheaper to mix bags or order a truck?
- Bagged concrete is far more expensive per yard. The breakeven point is usually around 1 to 1.5 cubic yards. For projects demanding 2 yards or more, ordering a ready-mix truck is much cheaper.
- How do I mix bagged concrete properly?
- Empty the bags into a wheelbarrow or mechanical mixer, form a crater in the center, and slowly add the instructed amount of water. Mix until it achieves a thick, oatmeal-like consistency without dry clumps.
