The calculators on this site provide estimates only for general informational purposes. Actual material needs vary with site conditions, product sizes, compaction, cuts and waste. Always verify quantities with your supplier and confirm design, structural and safety requirements with your local building code and, where appropriate, a licensed professional. References to code (such as typical IRC values) are labeled as typical and may not match your jurisdiction.

The site is provided “as is” without warranties. We are not liable for any loss arising from use of these estimates. Call 811 before you dig.
