Calculator disclaimer

BuildYard calculators are planning tools. They provide estimates based on user inputs, mathematical formulas, and editable assumptions. They are not a substitute for professional judgment or project-specific verification.

No engineering or code approval

Calculator results do not constitute engineering, architecture, surveying, permitting, code review, inspection, safety approval, or any other regulated professional service.

Verify before ordering or building

Always verify field measurements, units, slopes, openings, waste, compaction, overlaps, product dimensions, density, yield, coverage, package quantities, manufacturer instructions, and supplier data.

Material and cost estimates

Material quantities are estimates, not purchase guarantees. Prices are planning inputs, not offers or live quotations.

Safety and regulated work

Use qualified professionals and follow applicable codes, permits, manufacturer instructions, utility-location procedures, and jobsite safety requirements.

Use at your own risk

You are responsible for decisions made using calculator results. Review our Terms of Use and Calculation Methodology.
