Deck Vs Patio Cost Calculator
Compare the cost of building a deck versus a patio from size, material, and complexity. Enter values for instant results with step-by-step formulas.
Formula
Total Cost = (Material Cost x Area) + Labor + Structural + Extras
Material cost per square foot times the total area gives the base material cost. Add labor, structural framing (for decks), grading and base preparation (for patios), railing, and permits for the full project cost.
Worked Examples
Example 1: 300 sqft Composite Deck vs Concrete Patio
Problem: Compare building a 300 sqft composite deck (3ft elevation, 40ft railing) versus a concrete patio. Labor rate $50/hr.
Solution: Deck: Material $6,600 + Framing $2,850 + Railing $1,400 + Labor $2,250 + Permit $300 = $13,400\nPatio: Material $1,800 + Base $1,500 + Labor $1,500 = $4,800\nDifference: $8,600
Result: Deck: $13,400 ($44.67/sqft) | Patio: $4,800 ($16.00/sqft) | Patio saves $8,600
Example 2: 10-Year Total Cost of Ownership
Problem: Same 300 sqft area. Composite deck maintenance $0.50/sqft/yr, concrete patio $0.30/sqft/yr over 10 years.
Solution: Deck maintenance: 300 x $0.50 x 10 = $1,500\nPatio maintenance: 300 x $0.30 x 10 = $900\nDeck 10yr total: $13,400 + $1,500 = $14,900\nPatio 10yr total: $4,800 + $900 = $5,700
Result: 10-Year Total: Deck $14,900 | Patio $5,700 | Patio saves $9,200 over 10 years
Frequently Asked Questions
Is it cheaper to build a deck or a patio?
In most cases a patio is cheaper than a deck to build. A basic concrete patio costs between $6 and $15 per square foot for materials and installation, while a simple pressure-treated wood deck starts around $15 to $25 per square foot and composite decking ranges from $30 to $60 per square foot fully installed. The cost gap widens further when the deck requires elevation above ground level because structural posts, beams, and additional framing add significant expense. However, the comparison is not always straightforward. A high-end flagstone patio with extensive grading and drainage work can approach or exceed the cost of a basic wood deck. Your specific site conditions, including slope, soil type, and drainage requirements, heavily influence the final price.
What are the main cost differences between deck and patio materials?
Deck materials range widely in price: pressure-treated lumber costs $8 to $12 per square foot, cedar runs $14 to $20, composite decking is $22 to $35, and exotic hardwoods like Ipe can reach $30 to $50 per square foot. Patio materials also vary: poured concrete costs $6 to $10 per square foot, concrete pavers range from $10 to $18, stamped concrete is $12 to $20, and natural flagstone runs $15 to $30. Beyond the surface material, decks require structural framing lumber, hardware, and fasteners that add $5 to $15 per square foot depending on height and complexity. Patios require gravel base and compacted sand which typically add $3 to $6 per square foot.
How does elevation affect deck building costs?
Deck elevation is one of the biggest cost multipliers in deck construction. A ground-level deck sitting just inches above the soil may need only minimal framing and no railing, keeping costs similar to a patio. However, as elevation increases, costs rise substantially. At 3 to 4 feet of elevation, you need deeper concrete footings, taller support posts, larger beams, and code-required railings with balusters. A deck at 8 feet or higher may require engineered plans, additional cross-bracing, and stairways. Railings alone can cost $30 to $60 per linear foot installed. Each additional foot of height adds roughly $1 to $3 per square foot to the overall project cost for structural requirements.
