Estimate your decking material cost.

Use your actual deck dimensions and local board prices to compare stock lengths, estimate fasteners, and see a material cost per square foot. This is a decking-material estimate, not a full installed-deck quote.

What is included

A purchase estimate, not an installed-deck quote.

Decking boards

Uses the stable board-layout engine to compare 12, 16 and 20 ft stock using the prices you enter.

Estimated screws

Uses the current face-screw planning estimate, rounds up to whole fastener packs, and uses the pack size and price you enter.

Your project extras

Optional delivery, hardware, labor, railing, permit and demolition estimates are kept separate from the decking-material total.

Common questions

Deck cost calculator FAQ

Does this include labor?

Labor is not guessed for you. If you already have a labor estimate, you can enter it under Optional project costs and it will be added to the project budget.

Are the board prices live retailer prices?

No. Enter the prices you can actually buy at locally. That keeps the estimate transparent and avoids pretending that a national price is your price.

Does this include framing and railing?

The calculator does not calculate structural framing or railing quantities. If you already know a railing, hardware or other project cost, you can add that amount to the optional budget fields. Structural sizing remains outside this tool.
