How to calculate deck board material cost
This calculator finds the total material cost for deck boards by multiplying the number of boards needed by the cost per board — a straightforward budgeting step once you know your board count from a quantity calculation.
How the calculation works
Material cost = Deck board quantity × Cost per deck board unit. Simple multiplication of quantity by unit price, giving the material subtotal before labor, fasteners, or other decking hardware.
Example
120 deck boards needed, at $28 per board (a mid-range composite decking price point): Material cost = 120 × $28 = $3,360.
Frequently asked questions
Does this include fasteners and framing lumber?
No — this calculates only the cost of the deck boards themselves. Joists, beams, posts, and fasteners (screws or hidden clips) are separate costs to budget on top of this figure.
How much do deck boards typically cost?
This varies enormously by material — pressure-treated lumber is typically the least expensive, followed by basic composite, with premium composite and PVC decking costing considerably more per board. Check current pricing for your specific chosen material.

Pro Tips for Deck Board Material Cost
- Get your board quantity from a proper deck-board quantity calculation first (based on deck area and board coverage), then use that figure here for the cost total.
- Composite, PVC, and pressure-treated lumber all have significantly different price points — make sure the per-board cost reflects the actual material you're pricing.
- This figure covers board material only — fasteners, joists, framing lumber, and labor are separate costs to add for a full project budget.
Common Deck Board Material Cost Mistakes to Avoid
- Using a board quantity that doesn't already include a waste allowance, which will understate the true material cost once cutting waste is factored in.
- Forgetting that this total is boards only — treating it as the full decking project cost without adding framing, fasteners, and labor.
