Terms and disclaimer
Use estimates as a starting point
These calculators provide informational estimates based on the measurements and options you supply.
Estimates, not project design
Verify important quantities, specifications, and purchase amounts before relying on a result. The tools do not replace engineering, architectural, trade, safety, or legal advice.
Scope and local requirements
Footing and round-form dimensions are supplied by the user; the site does not determine structurally appropriate dimensions. Building codes, jurisdictional requirements, site conditions, product instructions, and manufacturer yields can vary. Confirm the requirements that apply to your project.
Products and yields
Bagged-concrete yields are nominal reviewed assumptions, not a guarantee for every mix, manufacturer, batch, or job condition. Check the selected product label and allow for project-specific loss only after making an informed decision.
No warranty of project suitability
Useful Figure is provided without a warranty that an estimate is suitable for a particular project. To the extent permitted by applicable law, you remain responsible for how you use a result and for verifying it before acting.
