Premix vs Mixing Your Own
Ready-mix or bags? The right choice depends on your volume, access and how much your time is worth.
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
| Method | Typical 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.
