Quick answer
How Many Bags of Concrete Are in a Yard?
A cubic yard of concrete equals about 60 bags of 60-pound pre-mix or 45 bags of 80-pound pre-mix.
Quick answer
How Many Bags Are in a Pallet of Concrete?
A standard pallet of 80 lb concrete bags holds 42 bags (3,360 lbs). A 60 lb pallet holds 56 bags. A 40 lb pallet holds 80 bags.
Quick answer
How Much Does a Bag of Concrete Cover?
An 80 lb bag of concrete makes 0.6 cubic feet of mixed concrete. A 60 lb bag yields 0.45 cu ft; a 40 lb bag, 0.3 cu ft.
Quick answer
How Much Does Concrete Cost?
Ready-mix concrete costs $125–$175 per cubic yard delivered in 2026. Installed (with labor and prep) costs run $8–$12 per square foot for a standard residential slab.
Quick answer
How Many Concrete Blocks Are on a Pallet?
A standard pallet of 8×8×16 concrete blocks (CMU) holds 90 to 110 blocks. Smaller 4×8×16 blocks come 144 per pallet; 12×8×16 blocks come 60 per pallet.
Quick answer
How Many Bags of Concrete for a Fence Post?
A standard 4×4 fence post set in a 10-inch diameter, 30-inch deep hole takes about 1.5 cubic feet of concrete — 1.5 bags of 80 lb or 2 bags of 60 lb pre-mix. Always round up.
Quick answer
How Many Bags of Concrete for a 10×10 Slab?
A 10×10 ft × 4 in slab takes 1.23 cubic yards (33.3 ft³) — 56 bags of 80 lb pre-mix or 74 bags of 60 lb. At this volume, a short-load ready-mix delivery is roughly the same total cost as bagged but saves 8 hours of mixing.
Quick answer

FAQ
Frequently asked
Start with the general Concrete Calculator for any rectangular pour. Use the Slab, Pad, Floor, or Footing calculator when you want defaults tuned for that project type (slab thickness, footing depth below frost line, pad reinforcement, etc.).
A cubic yard equals roughly 60 bags of 60 lb pre-mix or 45 bags of 80 lb pre-mix. Above 1 yd³ ready-mix delivery is almost always cheaper than bagging — see the breakeven on each calculator.
