Concrete Calculator
Work out how many cubic yards of concrete a slab, patio, or pad needs — with a waste allowance so a short pour never stops the job.
Concrete needed1.36 cubic yards
Or 80 lb bags (small pours)~62 bags
Good to know
- Ready-mix trucks typically have a 1-yard minimum and charge short-load fees under ~4 yards.
- 4 inches suits patios and walkways; driveways usually need 4-5 inches with reinforcement.
- Order 5-10% extra — running short mid-pour creates a cold joint.
