Deck Cost Calculator
Calculate total deck project cost including materials, labor, waste, and taxes.
Formula & Explanation
The deck cost calculator estimates the total cost of a deck project. Material Cost = (Deck Area × Material Price) × (1 + Waste%) Labor Cost = Deck Area × Labor Price per Sq Ft Subtotal = Material Cost + Labor Cost + Railing Cost Total Tax = Subtotal × Tax % Total Project Cost = Subtotal + Tax Material costs typically range from $3-6/sqft for pressure-treated wood to $8-15/sqft for composite. Labor costs vary by region: $5-15/sqft is typical for professional installation. Waste allowance of 5-10% accounts for cutting, damage, and materials for repairs.
Assumptions
- •Material price per square foot is for deck boards only (not framing lumber)
- •Labor cost per square foot includes board installation only (not framing)
- •Railing cost is a fixed amount for the entire deck
- •Waste percentage applies to material cost only
- •Tax applies to subtotal (materials + labor)
- •Costs do not include permits, inspections, or structural work
- •Prices are estimates and should be verified with local contractors
- •Regional variations in labor and material costs not accounted for
Example Calculation
A 200 sqft deck project with $8/sqft materials, $5/sqft labor, and $500 railing costs approximately $3,521 including 8% tax.
