The Real Comparison

Bags look cheap per bag, but per cubic yard the picture changes fast. Multiply your full volume before comparing.

Cost per Cubic Yard

MethodTypical per cu yd (incl. materials)
Ready-mix (delivery permitting)Lower per cubic yard for medium+ pours
80 lb bags (~0.6 cu ft each)Higher per cubic yard once labor and seams are counted
Self-mix (sack + sand + stone)Between, depending on your local prices

When to Use Bags

  • Small pours under a cubic yard.
  • Sites a delivery truck can't reach.
  • Pours you must stage in separate batches.

When to Order Ready-Mix

  • Slabs over a cubic yard or so.
  • A driveway, garage floor or larger footing.
  • Any pour with limited labor — a truck saves hours.

Final Check

Run your cubic yards through the concrete calculator with your local bag and delivery prices to see the real break-even point.
