- Stairs
- Railings
- Fascia boards
- Skirting
Step 5: Review Cost Estimate
The calculator provides an itemized list of:
- Deck boards
- Joists
- Posts and beams
- Fasteners and connectors
- Estimated cost (labor not included)
Deck Calculation Formula (in plain text)
To understand the math behind it, here are the main formulas used:
1. Deck Area Calculation:
pgsqlCopyEditArea (sq ft) = Length (ft) × Width (ft) 2. Number of Deck Boards:
mathematicaCopyEditTotal Deck Boards = Area (sq ft) ÷ Area per Board (sq ft) Example: If a board is 6 inches wide and 12 feet long:
javaCopyEditArea per board = (0.5 ft × 12 ft) = 6 sq ft 3. Joist Calculation:
javaCopyEditJoists Required = (Deck Width in inches ÷ Joist Spacing) + 1 4. Total Cost Estimate:
pgsqlCopyEditCost = (Cost per Board × Total Boards) + (Cost per Joist × Total Joists) + Additional Features Example: 12×16 Deck Estimation
Let’s say you want to build a 12 ft by 16 ft deck using pressure-treated lumber:
- Deck Area: 192 sq ft
- Board size: 6″ × 12′
- Boards needed: 192 ÷ 6 = 32
- Joist spacing: 16 inches = 12 joists (approx.)
- Add railing and stairs
- Estimated cost: Around $1,800 – $2,500 (materials only)
This is just a rough estimate, but it provides a good idea of what to expect.
