Decking Cost Formula
The calculator uses the following standard formula:
Total Cost = Area × (Material Cost + Labor Cost) + Optional Features
Where:
- Area = Length × Width
- Material Cost = cost per square foot
- Labor Cost = installation cost per square foot
- Optional Features = sum of extras like railings, steps, or lighting
This flexible formula allows for a wide range of customization and accuracy.
Example Calculation
Let’s say you’re building a 12 ft × 16 ft cedar wood deck.
Your Inputs:
- Length: 12 ft
- Width: 16 ft
- Material Cost: $25/sq ft (cedar)
- Labor Cost: $12/sq ft
- Extras: Railings = $600, Lighting = $400
Step-by-Step:
- Deck Area: 12 × 16 = 192 sq ft
- Material + Labor Cost: 192 × ($25 + $12) = 192 × $37 = $7,104
- Optional Features: $600 + $400 = $1,000
- Total Cost: $7,104 + $1,000 = $8,104
So, your estimated total cost for the cedar deck is $8,104.
Estimated Costs by Material Type
| Material Type | Average Price per Sq Ft |
|---|---|
| Pressure-treated wood | $15 – $20 |
| Cedar or redwood | $20 – $30 |
| Composite decking | $30 – $45 |
| PVC/Vinyl | $35 – $50 |
| Ipe or hardwood | $40 – $60 |
Prices may vary depending on your region, supplier, and project complexity.
