Deck Construction Cost Formula
Transparent mathematical methodology explained in plain English.
Total Deck Cost = Area (Sq Ft) × (Framing Cost/Sq Ft + Surface Decking/Sq Ft + Labor/Sq Ft) + Railings + StairsCalculates total platform square footage and adds costs for joist substructure, deck boards, footings, railing linear feet, and stairway steps.
Variables Explained:
- Deck Dimensions (L × W): Length and width of deck surface in feet.
- Decking Material: Pressure-treated pine, Redwood/Cedar, or Composite (Trex / TimberTech).
- Elevation & Footings: Ground level vs elevated second-story deck.
- Railing Length: Linear feet of perimeter railing required.
16 ft × 20 ft (320 Sq Ft) Composite Deck with 40 Linear Ft of Railing
Itemizing materials and professional carpentry installation.
- Substructure Framing & Concrete Footings: 320 sq ft × $12/sq ft = $3,840.
- Composite Decking Boards & Hidden Fasteners: 320 sq ft × $16/sq ft = $5,120.
- Composite Railing System: 40 linear ft × $45/ft = $1,800.
- Stairway Build & Stringers: $750.
- Professional Labor (320 sq ft × $25/sq ft): $8,000.
- Total Turnkey Cost: $3,840 + $5,120 + $1,800 + $750 + $8,000 = $19,510.

What is the cost difference between wood and composite decking?
Pressure-treated wood costs $25–$45 per sq ft installed and requires annual staining/sealing. Composite decking costs $45–$75+ per sq ft installed but lasts 25–30+ years with virtually zero maintenance.
Do I need a building permit to build a deck?
In most US jurisdictions, any deck attached to the house or higher than 30 inches above grade requires a municipal building permit, engineered footing inspections, and code-compliant railings.
