The cost to build a deck in 2025 varies widely depending on size, materials, design complexity, and labor. Here are key points to consider:
- Average Cost : The national average cost to build a deck is around $7,300 to $8,200, with most homeowners spending between approximately $4,300 and $12,600
- Cost per Square Foot : Typical costs range from $30 to $60 per square foot. The lower end corresponds to basic materials and simple designs, while the higher end includes high-end lumber, second-story decks, or custom designs
- Size Examples and Costs :
- 10x10 ft (100 sq ft): $4,000 to $6,000
- 12x12 ft (144 sq ft): $5,760 to $8,640
- 14x20 ft (280 sq ft): $11,200 to $16,800
- 20x20 ft (400 sq ft): $16,000 to $24,000
These ranges reflect material and labor costs combined
- Labor Costs : Labor typically accounts for about 40% of the total cost. Labor rates usually range from $15 to $40 per square foot depending on complexity and location
- Material Costs : Materials can range from $2 to $45 per square foot. Pressure-treated wood is the most affordable, while exotic woods, composite, and PVC decking are more expensive but more durable
- Additional Costs : Building a deck can increase home insurance and property taxes. Multi-level or raised decks cost more due to added complexity
- Return on Investment (ROI) : Decks typically offer a 40% to 52% ROI, making them a valuable home improvement
In summary, a basic small deck might cost around $3,000 to $6,000, while larger or more elaborate decks can exceed $20,000. Planning according to size, materials, and labor will help you budget effectively.
