Estimate concrete volume for slabs and simple pours.
Quick planning, rough comparisons, and checking whether your assumptions are in the right range before you rely on final quotes or advice.
Review the assumptions below, then compare with related calculators if your decision depends on rates, eligibility, or provider-specific rules.
How this calculator works
- Concrete volume equals length times width times depth.
- A small overage is usually sensible for ordering.
- Depth should be entered in meters.
Worked example
A 5 m by 4 m slab at 0.1 m depth needs 2 cubic meters of concrete.
Important assumptions
- This version handles simple rectangular pours only.
- Ordering waste and compaction are not fully modeled.
