Order the right amount of concrete.
Turn a slab, footing or round column into cubic yards, metric volume and bag counts before the mixer arrives.

Concrete quantity calculator
03 Trust the number, not the guess
Read the model card.
Every result carries the version, date and boundary of the assumptions behind it. That keeps a useful planning range from looking like a promise.
Rectangular volume is length × width × depth; round columns use π × radius² × depth. The result is converted to yd³ or m³ and then to selected bag equivalents.
Example: A 12 × 12 ft slab at 4 in is 48 ft³ ÷ 27 = 1.8 yd³ before the allowance; add 10% only after calculating the base volume.
See data sourcesTaxes, permits, access, code, disposal, site conditions and local availability can change a written bid. Use the result to scope the conversation.
Why Renovation Range exists03 Read the result
Concrete volume, without
the guesswork.
Calculate cubic yards, metric volume and common bag equivalents from a slab, footing or round column.
Use the volume formula first.
For a rectangular pour, multiply length × width × depth, then convert the cubic-foot result to cubic yards. For a round column, use the cylinder formula and multiply by the number of columns.
Add a practical waste allowance for uneven forms, spillage and small measurement differences. The result is a planning quantity, so confirm the final mix and order with the supplier.
04 Make the estimate legible
No black box.
Just better context.
A useful estimate does not pretend to be a bid. It gives you a sensible range, names the assumptions, and makes the next conversation less lopsided.
Three numbers beat one.
Low, expected, and high show uncertainty honestly — especially when labor and site conditions vary.
Show your work.
Materials, labor, gates, removal, and permits stay separate, so you can see what changed.
Local is a promise.
We only call a number local when the underlying data is local. Otherwise, we label it a baseline.
05 Before you sign anything
Turn a ballpark
into a better question.
Bring the breakdown with you. A good contractor will be able to tell you which line items are realistic for your property and why.
See the checklist01Is removal and haul-away included?+
Ask whether demolition, loading, disposal fees and final cleanup are included or priced separately. A low quote can move quickly when haul-away is missing.
02What does the labor line cover?+
Have the contractor spell out preparation, installation, equipment, cleanup and the crew’s scope. Compare the same work line by line, not just the final total.
03Are permits, gates, and site conditions scoped?+
Confirm permit responsibility, gate count and hardware, access, grading, drainage, excavation and any conditions that were not visible from the initial measurement.
04What could move this range after the site visit?+
Ask what the contractor still needs to verify: exact quantities, soil, utilities, access, material availability, taxes, disposal and code requirements. Those are the honest range movers.
07 Read the fine print
The short version.
Is this a contractor quote?
No. It is a reference estimate built from the assumptions shown on the page. A site visit and written scope are still the final word.
Why does location change the number?
Labor, material availability, permits, and site conditions vary by market. The model shows the factor and the assumptions so you can pressure-test a quote.
