- Each material has a different cost per square foot.
- Select Add-ons
- Choose optional features like:
- Railing (linear footage)
- Stairs
- Lighting
- Custom finish
- These extras affect the final price.
- Choose optional features like:
- View Instant Estimate
- The calculator will generate a total price estimate, including labor and materials.
- Refine or Save

📐 Formula Used in the Calculator
Here’s the plain text formula used to estimate deck costs:
Total Deck Price = (Deck Area × Material Cost per Sq Ft) + Add-ons + Labor Cost
Explanation of Each Component:
- Deck Area = Length × Width
- Material Cost = Material type × Price per sq ft
- Add-ons = Sum of extras like railings, stairs, lighting
- Labor Cost = Fixed rate per square foot or percentage of total cost
Example Formula in Action:
- Length: 20 ft
- Width: 15 ft
- Material (Composite): $30 per sq ft
- Railing (20 linear feet): $25 per ft
- Stairs: $600
- Labor: $10 per sq ft
Step-by-step Calculation:
- Deck area: 20 × 15 = 300 sq ft
- Material cost: 300 × $30 = $9,000
- Railing cost: 20 × $25 = $500
- Stairs: $600
- Labor: 300 × $10 = $3,000
Total Cost = $9,000 + $500 + $600 + $3,000 = $13,100
📊 Example Use Cases
🏡 Homeowner Budgeting
A homeowner planning a backyard transformation uses the calculator to compare pressure-treated wood and composite. The tool shows that while composite has a higher upfront cost, it reduces long-term maintenance expenses — helping make a cost-effective decision.
🧱 Contractor Client Quote
A contractor visits a client and uses the Deck Price Calculator to generate an on-the-spot estimate, boosting trust and streamlining the proposal process.
🧰 DIY Enthusiast
A DIY enthusiast calculates whether building a deck themselves would be cheaper than hiring a contractor. By adjusting the labor cost to $0, they instantly see the difference.
