Total lumber costHow lumber pricing works
Lumber is sold three ways, and the same board can cost different amounts depending on which one your yard uses. Board foot (144 cubic inches) is how most hardwood is priced — wider and thicker boards cost more. Linear foot charges by length only, common for trim and dimensional stock. Per piece is the sticker price on softwood like 2×4s. Price each board the way you'll actually be billed, add quantities, and this gives you the project total before you get to the register.
How do you calculate lumber cost?
Per board foot: (thickness × width × length in inches ÷ 144) × price. Per linear foot: length in feet × price. Per piece: the sticker price. Times quantity, summed across every board.
Board foot or per piece — which is cheaper?
Hardwood is usually per board foot; softwood (2×4s, 1×6s) is per piece or per linear foot. Enter the same board both ways and compare — the per-unit options let you see which is cheaper.
