Slab Costs: Should you buy Bags or a Ready-Mix Truck?
When pouring a concrete slab, the single biggest determiner of your project's total cost is the volume of material. This dedicated concrete slab cost calculator automatically cross-references local bag prices against standard ready-mix delivery rates.
The "1 Cubic Yard" Rule of Thumb
- Under 1 Cubic Yard (Small Slabs):
It's almost always cheaper to buy individual 60lb or 80lb bags from a hardware store. A commercial concrete truck will charge excessive short-load fees for anything under their minimum yardage requirement. - Over 1 Cubic Yard (Approx 45 bags of 80lb):
The sheer physical labor of mixing by hand offsets any minute cost savings. A ready-mix truck (averaging $150/yd + delivery) rapidly becomes the vastly superior and vastly cheaper option overall. Use the calculator above to see the precise intersection where a truck becomes recommended.
