Deck Material Calculator

Build a full deck materials list — decking, joists, ledger, beams, posts, concrete footings, hardware, railing, and labor — with an itemized bill of materials, U.S. pricing, a cost-by-category chart, and a downloadable PDF.

Quantities use typical residential framing rules and may differ from an engineered plan. Prices use 2024-2025 U.S. figures and vary by region and grade. Confirm spans, footings, and codes with a local pro — for planning purposes only.
