Deck Boards Cost

The Deck Boards Cost calculator estimates the cost of deck boards needed to cover an area, subfloor and joists, based on the unit price per square foot.

INSTRUCTIONS:  Choose units and enter the following:

• (L) Floor Length (running with joists)
• (W) Floor Width (spanning across joists)
• (BL) Deck Board Length
• (BW) Deck Board Width
• (UP) Unit Price per Board
• (JS) Joist Spacing 

Deck Board Material Cost (TC): The calculator will estimate the number of deck boards and the total cost in U.S. dollars.   However, this can be automatically converted into numerous other currencies (see list below) via the pull-down menu next to the answer.

The Math / Science

The formula for Deck Board Material Cost is:

TC = nB ⋅ UP

where

• TC = Total Cost of Flooring
• nB = Number of Deck Boards needed 
• UP = Unit Price per Area (e.g., $2.45 per square foot)

Deck Builder Calculator provides estimates for a simple rectangular deck project.  Calculator functions include the following:

• Deck Board Count: Computes the number of decking boards needed for your deck based on the size of the deck and the size of the decking boards.
• Deck Boards Cost: Computes the cost of deck board flooring based on a computed number of deck boards and the price per board.
• Decking Cost Estimate: Estimates the cost of wood board decking based on total area and unit pricing in dollars per square feet.
• Subfloor 4x8 Sheets: Computes the number of 4x8 sheets to cover floor/deck area.
• Subfloor Cost: Computes the cost of 4x8 sheets to cover fool/deck area.
• Deck Joist Count: Computes the number of floor joists needed for a deck.  It returns the number of joists and plate boards, square feet of area and the length of the diagonal.
• Joists on Beams: Computes the number of joists (2x dimensional lumber or i-joists), number of beams, number of joist hangers, and length of plate boards needed for a floor or deck with a span that might require one or more beams.
• Deck Joist Cost: Computes the total cost of the floor joist boards.
• Deck Stain and Sealer: Computes the amount of stain and sealer needed for a deck.
