United States calculator
Deck Building Cost Calculator
Estimate the cost to build a new deck. Adjust the deck size, decking material, whether it's ground-level or raised, and whether you add perimeter railing and a stair run to see an itemized low–high range for your project.

Deck Building Cost by state: typical ranges
Each range applies that state's labor index to the labor-share line items of the default project; materials stay at national prices. Select a state for its full local breakdown and calculator.

Common questions
How much does it cost to build a deck?
A new deck typically runs about $30–$60 per square foot installed, so a mid-grade 320 sq ft deck with railing lands around $8,000–$13,000. Pressure-treated pine is the budget option, while capped composite and PVC sit at the top. Use the calculator above for a range matched to your size, material, and features.
Is composite decking worth it over pressure-treated wood?
Composite and PVC cost more up front — often 30–50% above pressure-treated — but need almost no maintenance: no annual staining or sealing. Pressure-treated pine is cheapest to install but has the highest upkeep. Pick the material that matches your budget and how much maintenance you want.
Does a raised deck cost more than a ground-level deck?
Yes. A raised or elevated deck needs taller posts, more beams, deeper footings, and usually stairs and guard railing, which add framing material and labor. Toggle 'Raised / elevated deck' and 'Include a stair run' to fold that extra structure into the estimate.
